Focus Group vs BT Business
Focus Group edges ahead as the more flexible, broader-scoped B2B partner
Independently scored · last reviewed June 2026
Focus Group and BT Business are both credible one-stop B2B technology suppliers, but they occupy different parts of the market and win on very different grounds. BT Business is the UK's incumbent carrier: it owns the Openreach network, runs EE, employs thousands of security specialists, and can deliver connectivity to virtually any UK address with enterprise-grade resilience. If raw network reach and financial scale are your first criteria, BT is hard to argue with. Focus Group, by contrast, is the largest independent challenger in this space. Founded in 2003, it now serves more than 30,000 UK businesses and is backed by private equity firm Hg at roughly a £1bn valuation. It covers the same core bases (connectivity, telephony, IT and cyber) and adds business energy to the mix, giving it a breadth advantage that few rivals can match. Where BT stumbles is on price transparency, support satisfaction and value. Trustpilot scores diverge noticeably (Focus Group ~4.2 versus BT Business ~3.7), and BT's high proportion of 1-star reviews is worth paying attention to. Compare Business Costs scores the matchup 91 to 74 in Focus Group's favour.

Category by category
BT Business owns the Openreach access network and the EE mobile network, giving it unmatched UK coverage and a reliability score of 90 versus Focus Group's 85.
Focus Group's single-supplier model, managed account relationship and stronger support scores give it the edge over BT's mixed service reputation in voice and UC.
BT Business fields thousands of security specialists and enterprise-grade managed security partnerships with Fortinet, Palo Alto and Cisco, making it the stronger option at mid-market and enterprise scale.
Only Focus Group offers business energy, making it the only viable choice for buyers wanting to consolidate energy alongside comms and IT under one supplier.
Which should you choose?
Focus Group is the right call for SMEs and mid-market businesses that want to consolidate telecoms, connectivity, IT, cyber and energy with a single UK supplier under a managed account. Particularly useful for those frustrated by vendor sprawl, or looking for a more responsive alternative to the incumbents.
Full Focus Group review →BT Business suits mid-market to enterprise buyers and public-sector organisations where network resilience, nationwide Openreach reach, EE mobile coverage and large-scale managed security capability genuinely matter more than price or flexibility.
Full BT Business review →Focus Group earns the higher Compare Business Costs score (91 vs 74) through its exceptional category breadth (adding business energy to the usual comms and IT stack), stronger Trustpilot ratings, and a support model better suited to SMEs. BT Business is a legitimate choice for larger organisations where Openreach network reach, EE mobile and enterprise-scale cyber security are non-negotiable. For most UK businesses comparing these two, Focus Group is the more balanced and more flexible pick.
FAQs
How painful is switching from BT Business to Focus Group?
Switching your connectivity involves a standard industry migration process managed through Openreach, so your physical line or fibre circuit does not change, only the supplier billing you for it. Number porting for voice and VoIP is a routine process that Focus Group handles. The practical risk is during any overlap in contract terms: check your BT Business minimum period and any early termination charges before committing, as BT contracts at mid-market and enterprise level can run three to five years.
Which provider is a better fit for a small business with under 20 employees?
Focus Group is generally the stronger fit at this size. Its managed account model, broader product set and better Trustpilot scores point to a more attentive experience for smaller customers. BT Business serves the full market but its differentiation and pricing tend to work better at higher volumes. Very small businesses often report feeling under-served and find BT's support harder to deal with.
Neither publishes prices openly, how do I compare costs?
Both providers are quote-only for most of their B2B products. When requesting quotes, ask each for a like-for-like breakdown: line rental, call bundles, contract length, setup fees and any SLA penalties. Focus Group's weakness flagged on Compare Business Costs is limited public pricing transparency; BT's is premium pricing relative to challengers. Getting itemised quotes from both, then comparing total contract value rather than headline monthly figures, is the only reliable way to assess value for your specific requirement.
