As digital connectivity becomes increasingly important for business growth and productivity, over one million SMEs across the UK are still thought to be operating without access to full-fibre broadband, which could limit their ability to compete and serve customers effectively.

New analysis of UK broadband coverage data by the Uswitch business broadband experts shows that full-fibre connectivity access varies significantly between local authorities. For example, non-residential full-fibre access is highest at 97.4% in Nottingham and lowest at 8.6% in Harlow, highlighting gaps for local businesses.

Of the UK’s 3.17m SMEs, an estimated 2.16m are estimated to have access to full-fibre broadband. However, this leaves approximately 1.01m SMEs without full-fibre connectivity, meaning nearly one in three businesses could still be relying on slower or less reliable connections.

At the top of the scale, Buckinghamshire has 33,465 SMEs, of which an estimated 16,972 are likely without full-fibre broadband; Cornwall follows with 29,645 SMEs and around 15,453 likely lacking full-fibre access; and North Yorkshire has 37,090 SMEs, approximately 14,941 of which are likely not to have full-fibre connectivity, which could affect productivity and competitiveness.

Nationally, interest in business-specific broadband is surging. Searches for “business broadband comparison UK” are up 400% year on year, “fibre broadband for business” 336%, and “full fibre business broadband” 256%. This suggests that UK businesses are actively seeking faster, more reliable connections, highlighting the importance of addressing remaining infrastructure gaps at the local level.

Max Beckett, Uswitch business broadband expert, shares his top tips for picking the right business broadband, optimising your setup, and keeping your connection running smoothly:

“1. Match speed to business needs: Start by assessing how your team actually uses the internet. There’s no need to overspend on speeds you won’t use, but choosing a plan that’s too slow can quickly impact productivity. Smaller teams will typically need at least 25Mbps download and 3Mbps upload speeds to comfortably handle everyday tasks such as email, file sharing, video calls, and cloud-based software. Larger teams, of ten or more people, are more likely to benefit from a business broadband package of 150Mbps or higher.

“Exact requirements will vary depending on the type of business you run, how reliant you are on real-time connectivity, and the complexity of the tasks your team carries out, so it’s worth reviewing your needs before choosing a package.

“2. Consider the number of employees: Slower packages may be enough for small businesses with only a handful of employees using the internet for basic tasks like online browsing, email, and research. However, as the number of employees and devices grows, and tasks become more complex, the demand for faster broadband increases.

“3. Optimise your setup: Place routers centrally, limit interference, and consider business-grade equipment. Small adjustments can dramatically improve connection quality across your office or remote teams.

“4. Avoid broadband bottlenecks: Use network management tools to monitor, control, and optimise your network, helping identify congestion points and keep your connection running smoothly”.
