About BroadbandBackup

BroadbandBackup is an independent information site about keeping a UK home or small business online when the main broadband line fails. It is written for people without a technical background: anyone who works from home, runs a small firm, relies on a digital landline, or has simply had one outage too many.

What you will find here

• Broadband backup in the UK: the complete guide: why connections fail, what compensation pays, the ways to back up a line and whether you need one.
• 4G and 5G backup broadband: routers, SIMs, data plans, signal checks and real two-year costs.
• Business broadband backup: downtime costs, repair levels, dual-WAN, phones and card payments.
• How to set up automatic failover at home: three setups, detection settings, a test drill, batteries and troubleshooting.
• ISP backup vs DIY vs satellite: provider add-ons brand by brand, DIY kits, Starlink and household verdicts.

What we do not do

• We do not sell broadband, routers or SIMs, and we are not a provider, network or comparison site.
• No provider or manufacturer pays to appear on the site, and we do not recommend particular deals.
• We carry no advertising, affiliate links, sponsored content or tracking.

Accuracy

Every guide shows the date its facts were last checked and lists its sources, mainly the regulator Ofcom, Openreach, the providers' own published terms and established specialist sources. Prices, coverage and rules change, so confirm the details with a provider before you buy. Read more in our editorial policy.

The guides are general information, not legal, financial or technical advice for your particular situation.
