Report Examines How AI Can Improve Energy Savings in UK Telecoms Networks | ISPreview UK

Original article ISPreview UK:Read More

A whitepaper from the Digital Connectivity Forum (DCF), an industry think-tank, has attempted to highlight how AI (Artificial Intelligence) technologies can help the UK telecoms (broadband, mobile etc.) industry reduce emissions, strengthen climate resilience, and meet increasingly demanding regulatory and investor expectations.

The somewhat basic high level overview – ‘AI for Sustainability: Accelerating Net Zero in the UK Telecoms Sector‘ (PDF) – seems unlikely to hold too many surprises for network operators, many of which have already begun adopting so-called AI technologies to help cut energy consumption (e.g. all the major UK mobile operators are doing things in this area – examples here, here and here), get more out of their infrastructure and improve data processing to aid customer support.

NOTE: Often the use “AI” in such networks is just re-branded marketing for modern machine learning algorithms, rather than more sophisticated AI solutions like ChatGPT.

The new report identifies six domains that could benefit from AI, including energy optimisation, customer carbon reporting, upskilling for sustainability literacy, Scope 3 & Supply Chain improvements, sustainability focused decision-making and climate resilience & adaptation. But it also makes several recommendations to help deliver AI results.

Recommendations

  • Governance for Sustainable AI: Establishing cross functional oversight and ethical standards.
  • Developing the right data and technology foundations: Building scalable, trustworthy, and efficient data platforms.
  • Embedding ‘sustainable by design’ within AI development: Embedding ESG principles into AI design and prioritising energy-efficient models.
  • Assessing AI’s environmental impact: Using tools and methodologies to assess and report AI’s footprint.
  • Mitigating AI’s environmental impact: Optimising models, hardware, and infrastructure to reduce energy and carbon intensity.
  • Educating employees on Sustainable AI: Upskilling teams across roles and lifecycle stages to embed sustainability into AI.

Alex Mather, Head of the DCF, said: “AI has a critical role to play in helping the telecoms sector deliver Net Zero, improve resilience and unlock long-term value. This paper makes clear that success depends on a dual approach – using AI to drive sustainability outcomes while ensuring AI itself is deployed responsibly and sustainably. We hope this report provides a practical roadmap for industry leaders and policymakers alike.”

Grain Start Expanding UK Full Fibre Broadband Network in Nuneaton | ISPreview UK

Original article ISPreview UK:Read More

Carlisle-based broadband internet provider Grain, which last year secured a £225m funding boost (here) and has so far built their point-to-point full fibre (FTTP) network to cover 270,000 UK premises (aiming to reach 600,000 in the future), has revealed that they’ve begun to deploy their network across the Warwickshire (England) town of Nuneaton; home to around 88,000 people.

The town itself is already well covered by gigabit-capable broadband from both Virgin Media (inc. nexfibre) and Openreach’s respective full fibre networks. A number of alternative networks have also conducted small deployments in parts of the town, including OFNL (FibreNest), Glide and Hyperoptic. Suffice to say that there may be just enough space in the market for a serious push by another altnet.

NOTE: Grain has so far secured funding deals worth somewhere around £500m via Equitix, Albion Capital, Pinnacle Group, German Landesbank Nord L/B, HPS Investment Partners, LLC etc.

As usual, Grain hasn’t revealed precisely how many premises they intend to cover in the town or when the build will complete, although they do confirm that the roll-out began last month and the first connections are due to go live during Spring 2026.

Recent data from local street works indicates that Grain will be focusing their initial roll-out around the suburb of Stockingford. However, we also noted that another altnet, LightSpeed Broadband, appears to be starting a similarly modest deployment in the north and eastern sides of the town.

Richard Cameron, Grain’s CEO, said: “We’re excited to offer Nuneaton residents an internet service that can keep up with their digital lives.”

Openreach UK Leave Rural Wales Villagers Cut-off from Broadband for 6 Weeks | ISPreview UK

Original article ISPreview UK:Read More

A couple of homes in a remote rural area near the village of Llanelidan in Denbighshire (Wales) have been left without access to broadband and internet-connected TV services for six long weeks. The situation began after some nearby overhead lines (poles) were damaged in an unspecified event on 6th December 2025.

One of the residents, Howard (78), has heart issues and remains concerned that he might be unable to contact the emergency services in the event of a heart attack. The local area does receive a 4G mobile signal, although it’s described as being of a poor quality.

NOTE: Openreach’s national network includes over 4 million poles across the UK, most of which are made of wood and around 9 metres high.

However, most of the complaints have been reserved for Openreach, which Howard’s neighbour, Christine Conway, said had failed to provide much information and “just keep saying ‘oh, it’ll be next week’ … It would be helpful if they could keep in touch with us, and say exactly what they’re planning on doing – and when.”

In fairness, Openreach are the underlying network provider, but it’s actually the retail broadband ISP that holds responsibility for keeping customers informed. Sadly, the article on the BBC News makes no mention of which ISPs are involved. The catch is that ISPs sometimes also complain that Openreach doesn’t always provide them with enough information, either.

A spokesperson for Openreach said:

“Part of our overhead network is damaged. However, because of the pole’s location, it requires some extra work. This was delayed while we got permission from the landowner to carry this out. We understand how disruptive it is not having access to broadband, and we’re doing all we can to get people reconnected as soon as possible.”

Openreach has previously informed ISPreview that it can take around 20 days to fix damaged poles, such as after a major storm (it’s unclear if this incident was caused by a storm). But over the years we’ve seen examples where, in rare cases of extreme damage, rural areas have been left to wait for several months before repairs (here, here and here). In urban areas, such issues are more likely to be resolved within hours, rather than days, weeks or even months.

Such long waits can stem from a variety of issues, such as with the need to seek prior permission for tedious traffic management, land access (as above), safety considerations, police investigations, the possible involvement of a power supply company and limited local resources etc. But provided the local homeowners are with a retail ISP that supports Ofcom’s Automatic Compensation scheme, then they could now be in line for a significant payout (full summary); although ISPs sometimes need to be nudged about this.

In the meantime, Openreach said they intend to carry out the repairs tomorrow (14th Jan 2026).

United Infrastructure Win Contract to Maintain Cornerstone’s UK Mobile Masts | ISPreview UK

Original article ISPreview UK:Read More

Mobile infrastructure company Cornerstone (CTIL), which was originally established as part of a UK network sharing agreement between O2 (Virgin Media) and Vodafone (Vantage Towers), has awarded construction company United Infrastructure the contract to maintain their national network of 16,000 telecoms (mast) sites.

The agreement means that United Infrastructure, specifically its ‘Connected’ business, will become the “sole provider” of planned preventative maintenance and reactive repairs across CTIL’s telecoms sites nationwide, including Northern Ireland and the Scottish Highlands and Islands.

As part of the framework, United Infrastructure said they will also work closely with Cornerstone to deliver “greater operational efficiency, enhancing visibility, streamlining reporting and refining milestone tracking” across the network, while not sacrificing any existing standards for health, safety and secure site access across. The company will further aim to create new apprenticeship roles across both field and office-based functions.

Andy Train, Chief Network Officer at Cornerstone, said:

“Safety, resilience, quality and assurance were central to our decision-making. United Infrastructure demonstrated clear alignment with our safety-first culture and the operational discipline required to maintain the UK’s largest passive infrastructure network, enable 5G rollout and enhance future connectivity ambitions.

This framework cements a foundational part of our strategy to maintain and enhance the UK’s critical national infrastructure and is central to how we protect our people, our customers, our partners, our landlords and the communities our sites serve, every day.”

Scott MacGregor, MD of Connected at United Infrastructure, said:

“We are extremely proud to have been selected by Cornerstone as their sole partner for this UK-wide maintenance programme. This framework reflects the strength of our business and our shared commitment to ensuring the reliability, resilience and future-readiness of the nation’s digital infrastructure.

We look forward to working collaboratively with Cornerstone to enhance their network through smarter reporting, streamlined delivery and a focus on sustainable, long-term asset performance.”

The framework for this is currently set to begin in May 2026.

Odido revives €1.1bn IPO plan | Total Telecom

Original article Total Telecom:Read More

News

The move would value the company at around €7 billion

The joint owners of Dutch telco Odido, Apax Partners and Warburg Pincus, are reportedly looking to take the company public, according to reports.

Sources say the move would value the business at around €7 billion, with the initial public offering (IPO) potentially raising €1.1 billion through the share sale.

The launch would come almost a year after the telco’s owners shelved a previous plan for an IPO.

Odido has around 8 million mobile subscribers. It also has around 1 million fixed broadband customers, which it serves via wholesale deals with Open Dutch Fiber, Delta Fiber, Glaspoort, and KPN.

Apax and Warburg were reportedly exploring launching an IPO for Odido in January 2025, having hired Barclays Plc, Goldman Sachs Group Inc. and Morgan Stanley to lead the process. However, this plan ultimately fell through due to market chaos related to US president Donald Trump’s tariff implementation.

Now, the global economic environment has somewhat settled, leading Apax and Warburg to reconsider the IPO, which could be initiated as early as this month.

However, anonymous sources with knowledge of the matter speaking to Bloomberg emphasise that no decision has yet been made and the IPO may not proceed.

Odido (then T-Mobile Netherlands) was acquired by investment firms Apax and Warburg for €5.1 billion in 2021. The company was rebranded as Odido in 2023.

Dragon WiFi Offer Temporary Internet Fix for Cornwall UK Areas Hit by Storm | ISPreview UK

Original article ISPreview UK:Read More

Network operator Dragon WiFi, which typically delivers a variety of broadband connectivity solutions across rural parts of South Wales and South West England, has informed the local authorities in Cornwall (England) that they’re willing to help set up temporary wireless internet solutions in areas that may remain disconnected following Storm Goretti.

The offer of assistance came after the local Liberal Democrat MP for St Ives, Andrew George, reported to the commons that he is aware of some areas that remain without working internet access. In response, Dragon WiFi has contacted the local authority in the hope of being able to identify precisely which areas remain offline and then deploying a temporary connectivity solution accordingly.

The proposed short-term solution is a Starlink (satellite backhaul) fed public WiFi Hotspot, which could be deployed from local cafe’s, pubs, village halls or shops – among other places – to help keep people connected until the main service has been restored.

So, while Dragon WiFi would prefer to work alongside the local authority, if anybody else knows of impacted areas within Cornwall, then they’d like to hear from you. “Storm Goretti has been quite destructive down here, but I think that some of the national news may have missed quite how much damage it’s caused,” said Aaron Coward, Dragon WiFi’s South West Business Lead, to ISPreview.

Eutelsat Orders 340 Extra OneWeb LEO Broadband Satellites from Airbus | ISPreview UK

Original article ISPreview UK:Read More

European satellite operator Eutelsat has announced that they’ve ordered a further 340 Low Earth Orbit (LEO) broadband satellites for their global OneWeb network from Airbus Defence and Space. This is on top of the planned 100 satellite extension that was previously procured in Dec 2024 (due to for delivery in late 2026); representing a total network expansion of 440 satellites.

OneWeb, which readers may recall was originally rescued from bankruptcy by the UK government and Bharti Global before later becoming a part of Eutelsat – with concessions (here), currently has 654 small (c.150kg) first generation (GEN1) LEO platforms in space – orbiting at an altitude of 1,200km (c.600 of them for coverage and the rest for redundancy). Plans also exist to “extend the constellation by a further 100 satellites by 2026” (here).

NOTE: Eutelsat has its HQ in Paris, while OneWeb is a subsidiary operating commercially as Eutelsat OneWeb, with its centre of operations remaining in London. BT and others have previously worked with OneWeb on several UK rural broadband trials (here and here).

The news that Eutelsat has now awarded the contract for a further 340 OneWeb satellites to Airbus Defence and Space is not a surprise, since Eutelsat indicated that they intended to add further spacecraft to the constellation in July 2025. But at the time the company hadn’t yet finalised the contract or confirmed who would build them (Airbus is a logical choice given their past involvement with OneWeb).

Crucially, the focus above is on “replacing early batches” of OneWeb’s satellites, which after several years are now said to be “coming to [the] end of operational life“. The availability of the new satellites will thus “assure full operational continuity for customers of the constellation” (LEOs are smaller satellites and only designed to function for a few years before being de-orbited).

However, the new satellites will “integrate technology upgrades“, including advanced digital channelizers, enabling enhanced onboard processing capabilities as well as greater efficiency and flexibility. They will also incorporate optimized architecture designed to maximize long-term operational performance. In addition, Eutelsat intend to use the new batch of satellites to evaluate “opportunities for new business cases, notably through embarkation capabilities for hosted payloads“.

Jean-François Fallacher, Eutelsat CEO, said:

“We are pleased to rely on our long-standing partner, Airbus, for the procurement of these latest satellites. They ensure service continuity for the growing number of our customers and distribution partners benefiting from the unparalleled performance of our ubiquitous, low latency LEO capacity, and enable us to pursue our growth path, building on the 80% topline expansion delivered in 2025.”

OneWeb has previously talked about future GEN2 satellites as including more data capacity (faster broadband speeds), 5G mobile support and, possibly, also the introduction of enhanced navigation and positioning features (GNSS). But it’s currently unclear whether the additions mentioned above will deliver on this, or if they’re more of a mild mid-life upgrade to the existing GEN1 capabilities. Similarly, we don’t yet know if they’ll be placed into a different orbital altitude, which could impact their coverage and performance.

However, the mention of “hosted payloads” above is interesting, particularly since this usually reflects third-party instruments or modules that can “piggyback” on the new satellites (i.e. sharing its bus, power, and data systems). This could enable commercial partners to request the addition of specific features ahead of launch, such as 5G or GNSS etc.

Just as a reminder. The UK government last year agreed to commit a further £140m (€163.3) of public investment to help Eutelsat grow and expand this constellation, which gives them a 10.89% share in the business.

Ookla Name Three UK Fastest and O2 Slowest for 5G Mobile Broadband in H2 2025 | ISPreview UK

Original article ISPreview UK:Read More

Network testing giant Ookla, which collects data from consumers via their popular broadband Speedtest.net service, have released their latest Q3-Q4 2025 (H2) study into the speed of 5G based mobile broadband networks across the United Kingdom. The results reveal that Three UK continues to be the fastest provider, while O2 (Virgin Media) was the slowest.

The catch is that mobile broadband performance can be a very difficult thing to pin down because users are always moving through different areas (indoor, outdoor, underground etc.), using different devices with different capabilities and the surrounding environment is ever changeable (weather, trees, buildings etc.). And that’s before we consider the other issues, such as network capacity and varying spectrum use at different cell sites. But these caveats are true for all the operators in this study.

NOTE: The study used data collected from 413,966 samples (users) and 2,367,423 speedtests, conducted across the UK, to identify the best performing 5G mobile operator.

Overall, Three UK once again secured the top spot with a “Speed Score” of 53.46 (down from 55.17 in H1), median average download speeds of 214.02Mbps (down from 227.77Mbps) and median upload speeds of 13.08Mbps (unchanged). The full results below also include some extra figures for all of the major mobile operators.

Just to be clear, Ookla’s Speed Score is produced using data from various metrics, including the 10th, 50th, and 90th percentiles of download and upload throughput and loaded latency. Different aspects of these have different weightings in the final score, for example, download speed is most relevant (70%) to the end result, while upload speed counts for 20% of the weighting and latency just 10%.

Fastest UK 5G Operators by Speed Score – H2 2025 (H1 2025)

1. Three UK – 53.46 (down from 55.17)

2. Vodafone – 43.05 (down from 45.04)

3. EE (BT) – 36.73 (down from 38.46)

4. O2 (Virgin Media) – 30.70 (down from 31.13)

We expect the results for Three UK and Vodafone to slowly change as they bring their respective networks together following the recent merger, but for now Ookla still list them as separate networks.

Starlink Add Grok-powered AI Chatbot to Support Broadband Users on Website | ISPreview UK

Original article ISPreview UK:Read More

The Starlink service from SpaceX, which offers ultrafast broadband speeds to the UK and globally via a massive constellation of satellites in Low Earth Orbit (LEO), appears to have expanded the availability of their Grok-based AI chatbot to support customers on their website. The service was already added for users of their App a few months ago.

The chatbot can be accessed from the “Contact Support” link on the checkout page of the website, which then requires you to enter a few personal details (name, email etc.). After that you’ll be sent an email that includes a link, which opens a page with the new AI “Chat powered by Grok” support service.

NOTE: By the end of 2025 Starlink’s global network had 9 million customers (up from 6m in July 2025). The service had 110,000 customers in the UK as of July 2025 (up from 87,000 in 2024) – mostly in rural areas.

In theory, this should make it easier for customers to get answers to their technical queries without needing to manually search through the service’s mass of technical and legal documents, although we did find that it typically took between c.14-16 seconds to return a response to even basic queries. But take note that the chatbot is restricted to only being able to answer questions about Starlink’s current service (i.e. it won’t respond to queries about unrelated topics).

On the other hand, consumer sentiment toward the use of AI chatbots tends to be quite mixed, with many viewing it as being more of a negative (i.e. a way of reducing the number of actual humans that are available to provide support). On the other hand, if such systems do end up making it quicker and easier for customers to get their issues resolved, then that would still be a positive change.

Starlink currently has around 9,500 satellites in Low Earth Orbit (c.6,000 are v2 / GEN2 variants) – mostly at altitudes of between c.340-525km. Residential customers in the UK usually pay from £55 a month for the ‘Residential Lite’ unlimited data plan (kit price may vary due to different offers), which promises downloads of up to 250Mbps (175Mbps average) and uploads of c.15-35Mbps. Faster packages exist at greater cost, while cheaper, albeit more restrictive (data capped), options also exist for roaming users (e.g. £50 per month for 50 GigaBytes of data).

UK Broadband Provider G.Network Files Notice to Appoint an Administrator UPDATE | ISPreview UK

Original article ISPreview UK:Read More

Alternative network operator and UK ISP G.Network, which has deployed a gigabit speed full fibre (FTTP) broadband network across parts of London, has followed up last week’s report – that they’d been acquired by distressed debt specialist FitzWalter Capital (here) – by officially filing a Notice of Intention (NoI) to appoint an administrator.

The provider originally aspired to expand their Fibre-to-the-Premises (FTTP) infrastructure to cover 1.3 million premises in London by the end of 2026. But not unlike many other altnets, they’ve since been impacted by an increasingly competitive environment and rising costs (high build costs, high interest rates etc.), which resulted in job cuts and a greater focus on commercialisation instead of new fibre build (here). However, their efforts to commercialise will have faced some pressure from gigabit-capable rivals, such as Hyperoptic, CommunityFibre, Virgin Media (nexfibre) and Openreach (BT) in some of the same areas.

NOTE: G.Network’s latest annual accounts to March 2024 (here) said their “wholly-owned and hard to replicate FTTP ducted network” now covered 416,000 premises, of which 361,000 are said to be “connectable under the Ofcom Connected Nations definition”. But an independent estimate in Sept 2025 put them closer to 255,100 as Ready For Service (here), while reports suggest they’re home to just 25,000 customers.

Despite the challenges, the operator had continued to receive funding from long term equity investor Universities Superannuation Scheme (USS), including £85m in June 2024 (here). The company’s most recent accounts also reported an 85% increase in turnover to £10.2m in FY2024 and a gross profit of £7.3m (up 62%), with total assets of £453m (up from £394m). But they also suffered an operating loss for the year of £52.8m (down from £67.2m) and are estimated (Enders Analysis) to be carrying a net debt of over £300m.

Suffice to say that last week’s reported acquisition by FitzWalter Capital (FWC) made sense for a network that seems to be struggling to find a buyer for consolidation. As James Ratzer, Analyst at New Street Research, said: “Given the company’s losses, it is hard to see an obvious standalone business case. We presume the buyer is a short-term holder and would be keen to sell to another provider as soon as possible.”

The exact approach that FWC intended to take, with respect to tackling the company’s liabilities, didn’t become clear until Monday night when sources pointed ISPreview toward a new legal case (CR-2026-000171). In short, G.Network Communications Limited, via law firm Taylor Wessing LLP, has made a new application in the shape of a “Notice of Intention to appoint an administrator“. According to our sources, Alvarez & Marsal in London will take on the task.

Administration often occurs when a company, such as one that is in financial difficulty, is put into the hands of an administrator. The administrator then decides whether they can help the company to continue running or sell it off for a good price.

Once in administration, the company is often protected from legal action by people or organisations who are owed money (creditors). Administration can also mean that the company may not have to pay all its debts in full, but if deemed necessary, they can still be wound up.

The expectation here is that this may provide a way for FWC to sell the network and its customers to a new owner (consolidation). But it remains to be seen whether this will be a pre-packaged process (i.e. they may already have a new owner – likely a network consolidation partner in mind) or something more long winded.

ISPreview has contacted G.Network for comment and will update as soon as they respond.

UPDATE 10:22am

We’ve just received a statement from Alvarez & Marsal.

Richard Beard, Joint Administrator and MD of Alvarez and Marsal, said:

“G.Network will continue to trade as normal, with its full-fibre network operating as before and services being delivered to existing and new customers across London without interruption.

Our appointment as administrators provides a platform for a restructuring, and we will work closely with the management team to create a sustainable business. We understand that this will be an unsettling time for G.Network’s employees. We appreciate their hard work and will be keeping them updated on the restructuring process.

The Company benefits from a robust network and a strong customer base. We would like to invite any parties interested in acquiring the business to contact us.”

The announcement noted how “G.Network’s capital structure has become unsustainable in recent years and in response, the Company has been exploring options with its stakeholders, including seeking new investors“, which is of course what led to the completion of the sale of its secured debt and equity to affiliates of FitzWalter Capital in early January 2026.

The Joint Administrators state that they’ve “secured sufficient funding for the administration process, which will enable the Company to continue to trade as normal and to connect new customers. They do not anticipate that there will be any adverse impact on customers“. The Joint Administrators will be marketing the business for sale in the “coming weeks“.
