📡 The Main UK Business Broadband Providers
When shopping for business broadband you'll encounter network operators (BT Openreach, CityFibre, Virgin Business) and resellers who provision over those networks. Telexico is a reseller with access to both Openreach and CityFibre infrastructure, which gives businesses more choice than going directly to BT or Virgin.

🔌 Openreach vs CityFibre — Does the Network Matter?
Both Openreach and CityFibre build and own the physical fibre. Openreach has the largest UK footprint — around 30m premises passed. CityFibre is building in 285 UK towns with denser infrastructure in covered areas, often resulting in faster engineer response and newer cabinet equipment.
If your premises is in a CityFibre town (check their rollout map), it's worth comparing a CityFibre-provisioned product alongside standard Openreach FTTP — the monthly price is often similar but SLAs can be tighter.
🛡️ What Actually Determines Your Broadband Reliability?
- Infrastructure age: Older copper-to-cabinet (FTTC) connections are more prone to faults than full-fibre FTTP.
- Contention ratio: Business broadband products have lower contention than residential. Check what ratio your provider guarantees.
- Engineer SLA: How quickly does the provider respond to a fault? Next business day is standard; same-day is available on premium products.
- 4G failover: The fastest insurance against downtime. Telexico includes this on all business broadband products.
💷 The Hidden Costs in Business Broadband
- Static IP address: £5–10/month extra with most providers — essential for VoIP and remote access.
- Contract break fees: Typically the remaining months' rental. Read this clause carefully.
- Engineer visit charges: BT charges £120+ for a visit if the fault is deemed to be on your side of the network.
- Annual price rises: Virgin Business and BT apply inflation-linked increases mid-contract.
