Connectivity is now essential to everyday life, and people expect fast, reliable access to global news, social media, voice, music and video. In business, those expectations extend to the workplace, where poor connectivity can quickly affect productivity, customer experience and security.
Reliable and secure connectivity underpins everything from collaboration tools and cloud applications to telephony and customer service. Yet many organisations still rely on connections that are underpowered, inconsistent or lacking resilience.
In this article, we explain what’s changing across the UK, outline what to review in your connectivity strategy in our four-point checklist, and share practical steps to improve performance, resilience and long-term value.
Why connectivity is now business-critical infrastructure
A problem with a single workplace connection can affect multiple people at once. The impact goes far beyond an annoying minor interruption: it can reduce productivity, disrupt customer service, and affect staff experience. In some business environments, the cost is immediate. In retail, an outage may prevent card payments. In education, it can interrupt access to learning platforms and safeguarding systems. In healthcare, it can affect access to patient records and prescribing tools. Across all sectors, outages create disruption.
As organisations move more services to the cloud and replace analogue voice with digital telephony, connectivity becomes more important. Systems that once operated separately now depend on the network. For instance, an office that previously had a local server and a traditional telephone network could still make telephone calls if the email server failed. Now the email server and the phone system are in the cloud, if your connection is slow, overloaded or unavailable, email, voice, collaboration tools and business systems can all be affected at the same time. The options become either a rapid fix or people going home to work, assuming the nature of the work allows it.
UK broadband availability and full-fibre adoption
In its Connected Nations update in Spring 2026, Ofcom addresses the availability, build-out and adoption of fixed-line and wireless networks across the UK and provides a valuable insight into the expanding availability of fibre, mobile (4G/5G) and satellite connectivity.
Drill into the data and looking at business premises and the availability of full fibre, the figures are very encouraging. Just 56% of business premises had access to full fibre in September 2023, and that figure grew to 81% by January 2026, which is approximately 8.5m additional premises in under 18 months. The national picture is encouraging, but availability doesn’t automatically translate into adoption. Many organisations are still using older services, often because of contract cycles, lack of awareness, or uncertainty about what level of performance and resilience they really need. That’s why regular review is important.
The need to regularly review your connectivity requirements
We often see organisations stay on legacy or rolling connectivity contracts and assume that the same service will still be suitable at renewal. In reality, business needs change quickly. More cloud services, more locations, more remote users and more security requirements all place different demands on the network. Connectivity should be reviewed as essential infrastructure, not treated as a last-minute purchase.
Our checklist draws on our vast knowledge and experience and highlights four areas to review regularly so your connectivity continues to support current needs and future growth.
Your connectivity checklist:
-
Know your applications.
Where they sit and how critical they are. This can be harder than it sounds. Include cloud-based platforms, telephony, backups, CCTV, HR, finance and any specialist applications. Map where data is stored, and how data needs to flow between locations, including cloud services remote access and contingencies. And think about which services are most important to day-to-day operations.
- Know how much bandwidth you need and when you need it.
Usage patterns matter. Telephony is a good indicator of connectivity health. An early health warning is that you can hear your customers on the phone, but they might not hear you. If you use a broadband link, then the speed at which you can send data up the line is lower than the speed down the line. If an overnight backup overruns, then it could flood the uplink on a line. High-definition CCTV can also place a load on uplinks. - Know how resilient your connectivity really is.
Review your connectivity, SLAs, outage risks and backup options. Have you considered and accepted the risks of exceptions? If you have a backup connection, is it truly resilient? Or does it share infrastructure with your primary line? We commonly get asked for two broadband lines, one as the primary and the other for backup. In practice, those lines may be delivered from and use common infrastructure, and even the same provider, at the local exchange or even the telephone pole on the street. If one line fails, then the other may too. - Know the cost of disruption.
Compare connectivity costs with the operational and financial impact of downtime. How do your costs of disruption escalate over time? The proportionate costs and impact of distribution increase if you are highly reliant on fewer locations. The more your organisation depends on digital systems, the greater the cost of an outage.
Hard to reach locations
Fibre technologies usually offer the strongest combination of price performance, resilience and long-term value for business sites and remote workers. But it isn’t available everywhere and, while there is large-scale investment in progress, hard-to-reach locations, temporary sites and lower population density areas may still need a mix of technologies, including mobile or satellite, to achieve reliable service.
That’s why it’s useful to think beyond fibre alone. Ofcom’s reporting covers fixed broadband, mobile and satellite because each can play a role in both primary and secondary (resilience) line planning. A well-designed solution often combines different access methods so backup circuits don’t follow the same transmission routes as primary connections.
Bringing your connectivity all together
We regularly review what value we offer. Connectivity and telephony are at the core of everything we do, but both are now highly commoditised. One of our differentiators is our ability to provide you with connectivity from multiple vendors, allowing us to deliver optimum value.
In the UK, fixed line connectivity to premises is dominated by BT Wholesale, which provides services for around 1,400 providers and directly serves 92% of UK premises with copper broadband and two-thirds with full fibre. Additional tier one telecommunications providers have a mix of their own fibre to premises and presence in local exchanges, while alternative network providers (altnets) also have strong fibre presence in specific local areas across the country.
We have our own core network and have network to network interconnects (NNIs) with many tier one and altnet providers. These NNIs extend across fixed line, broadband and mobile connectivity. This means that by choosing us as your network partner, we can look at the location of your sites and provide the best mix of cost, resilience and availability across our single network with a cohesive service. We can advise on, and provide diverse connectivity to sites, addressing many of the geographic restrictions that might otherwise apply. Traffic between sites stays within our network, enhancing performance, whilst also offering all the benefits of direct internet access from each site.
In summary
High speed reliable internet access is now taken for granted due to wide availability for personal use, but organisations often overlook its importance and criticality in delivering higher level application services. The move to cloud services and digital telephony increase the demand for fast and reliable connectivity.
High speed broadband, including full fibre, is now widely available across the UK, and continues to improve. Businesses shouldn’t assume that availability alone guarantees the right level of service, as the right solution depends on your applications, locations, resilience needs and tolerance for downtime. By regularly reviewing applications, bandwidth requirements, connectivity, resilience and the cost of disruption, you can make better decisions about where to invest and how to support future growth
For many organisations, fibre fixed line connectivity provides the best combination of performance and availability but as it isn’t available in all locations with backup connectivity for reliance, using a secondary technology that uses a different route should also be considered. Our network provides direct access from multiple fixed line and mobile providers, helping customers to deliver access, performance and resilience benefits, even in hard-to-reach locations.
