UK Fibre Broadband: Openreach Dominates, But AltNets Fuel Competition & Future Growth
The UK’s full-fibre broadband rollout continues at pace, but a clear dynamic is emerging: Openreach is solidifying its lead, while independent providers – known as altnets – are playing a crucial, and increasingly competitive, role. Recent data reveals a landscape of expanding coverage, regional disparities, and a potential slowdown as network build-outs mature. This article breaks down the current state of UK fibre, what it means for you, and what the future holds.
Openreach’s Expanding Reach
As of the latest surveys, openreach now covers 58% of UK premises with full-fibre, reaching a total of 19.2 million homes and businesses. This represents a significant increase from 52% in March 2025. Their dominance is undeniable, but it doesn’t tell the whole story.
The Rise of AltNets
AltNets, while smaller individually, collectively provide services to just over 43.3% of premises – up from 40.3% previously. These companies are vital, especially in areas where Openreach’s FTTP (Fibre to the Premises) isn’t yet available. They often offer a compelling choice, sometimes with superior service and pricing.
Here’s a look at the leading altnets and their current coverage:
* CityFibre: 13% coverage (4.3 million premises)
* Netomnia/YouFibre/Brsk: 8% coverage (2.6 million premises)
* Nexfibre XGS-PON: 6% coverage (1.8 million premises)
* Virgin Media RFOG: 5% coverage (1.7 million premises)
* Community Fibre: 4% coverage (1.5 million premises)
* Hyperoptic: 4% coverage (1.3 million premises)
* Others: Collectively serve fewer than 1 million premises.
Why So Many AltNets?
The UK boasts a diverse broadband market, with numerous altnets challenging the established players like Openreach and KCom (in Humberside). This competition is good for consumers.It drives innovation, keeps prices in check, and ensures better service quality.
The Overbuild challenge
Interestingly,the rate of full-fibre rollout has slowed slightly. This isn’t necessarily a negative sign, but it’s partly due to “overbuilding.” this means both Openreach and multiple altnets are investing in the same areas. This happens for a few key reasons:
* Virgin Media’s Existing Network: Virgin Media already offers gigabit speeds via its DOCSIS 3.1 network, reducing the immediate need for full-fibre in some areas.
* AltNet Competition: Multiple altnets are vying for market share, leading to parallel infrastructure deployments.
* Openreach Expansion: Openreach is aggressively pursuing its goal of reaching 25 million premises.
Regional Variations in Gigabit Availability
Gigabit availability isn’t uniform across the UK. Here’s a regional breakdown:
* Northern Ireland: 96.9%
* England: 89%
* Scotland: 82.8%
* Wales: 82.3%
These figures highlight the ongoing work needed to bridge the digital divide and ensure consistent access to high-speed broadband across the country.
The Future of UK Fibre: Competition & Investment
The future looks shining for UK fibre, but continued investment and healthy competition are essential. Sebastien Lahtinen, a director at Thinkbroadband.com, points to several positive trends:
* Growing Competition: More altnets are entering the market, increasing consumer choice.
* Wholesale Agreements: More retailers are leveraging wholesale agreements, potentially boosting take-up rates.
* Increased Funding: Investor confidence is crucial for continued rollout.
Why Full-Fibre Matters – Beyond Speed
while the promise of speeds up to 5Gbps is exciting,the real benefit of full-fibre lies in its reliability. You’ll experience:
