Never let a broken line stop your business
For most businesses, losing internet means losing everything at once — email, cloud apps, VoIP calls and card payments. Backup connectivity removes that single point of failure with a second, independent link that takes over automatically if the primary connection fails.
We design failover to match your risk: a diversely-routed second fibre line for the highest resilience, or cost-effective 4G/5G failover that kicks in within seconds. Automatic switchover means staff and customers barely notice the outage happened.
It all ties into your router or SD-WAN and is monitored 24/7, so if the primary link goes down we're alerted immediately and your business keeps running while we get it fixed. Peace of mind that pays for itself the first time a line goes down.
- Carrier comparison for best price & lead time
- Project-managed install with progress updates
- Router & firewall configured and secured
- Ongoing monitoring and UK-based support

What backup connectivity costs
Automatic 4G/5G failover typically costs from £25 per month including router configuration; a second-line (dual broadband) failover starts from £60, and a resilient dual-carrier setup from £150. Switchover is automatic — most teams never notice the outage.
"From" prices reflect typical carrier pricing across Greater London on 36-month terms; your exact price depends on your postcode and building. Free availability check — quotes usually returned the same working day.
