Overview
- British Gas recommends insulating pipes and water tanks, with foam lagging, tank jackets and insulated tap covers available cheaply at DIY stores.
- Homeowners are told to prioritise exposed runs and colder spaces such as lofts, garages and basements, plus bends, valves and outside taps.
- The companies say frozen water expands and can crack pipes, leading to leaks and potential flooding when the ice thaws.
- British Gas advises keeping rooms between 18°C and 20°C in winter with a minimum indoor temperature of 10°C to avoid frozen pipes.
- Thames Water urges wider readiness: know the stop tap, bleed radiators, fix leaks, clear drains and gutters, and keep an emergency plumber contact, with more details on its website.
