British Gas has issued an urgent winter warning as temperatures across the UK are forecast to drop below freezing, putting tens of thousands of households at risk of losing heating and hot water. The energy giant says at least 54,000 homes may require urgent assistance in the coming days as frozen pipes and boiler faults surge during what is expected to be the coldest spell of the winter so far.
The warning comes as icy conditions spread nationwide, with schools closing in parts of the UK and weather alerts remaining in force.
Why British Gas Is Sounding the Alarm Now
According to British Gas, freezing temperatures dramatically increase the risk of frozen condensate pipes, particularly in modern condensing boilers. When water inside pipes freezes, it expands, causing pressure to build up. This can lead to cracks, leaks, or burst pipes, often leaving households without heating or hot water when temperatures are at their lowest.
Last winter alone, more than 1.2 million customers contacted British Gas engineers to fix heating and boiler issues, and the company expects over 50,000 emergency call-outs this week, making it the busiest period of the season.
Common Boiler Problems During Freezing Weather
British Gas engineers say the most frequent winter issues include:
- Frozen condensate pipes
- Boilers failing to ignite
- Burst or cracked pipework
- Loss of hot water and central heating
Joanna Flowers, a service and repair engineer at British Gas, said frozen pipes are “one of the most common issues we see during cold snaps,” but stressed that quick action can often prevent serious damage.

What To Do If Your Boiler Stops Working
If your heating or hot water suddenly stops working during freezing conditions, British Gas advises households to:
- Check for frozen pipes, especially the condensate pipe outside
- Gently thaw the pipe using hot (not boiling) water
- Place a hot water bottle over the pipe to speed up thawing
- Reset the boiler once thawed
If a pipe has burst, homeowners should turn off the water supply immediately, open taps to drain the system, and contact a qualified engineer.
The Exact Temperature to Set Your Heating
British Gas engineers recommend keeping your heating set to at least 7°C, even when you are not at home. This helps maintain minimal water flow through the system and significantly reduces the risk of frozen pipes.
Many smart thermostats, including Hive, feature built-in Frost Protection, while most radiators have a snowflake symbol setting designed specifically to prevent freezing.
How to Prevent Frozen Pipes This Winter
Experts say prevention is far cheaper than repair. British Gas advises households to:
- Lag exposed pipes with insulation from DIY stores
- Ensure boilers receive regular servicing
- Bleed radiators to improve efficiency
- Seal draughts around doors and windows
- Avoid heating unused rooms unnecessarily
Insulating pipes is described as the single most effective step to prevent costly winter damage.
Financial Help Available for Energy Bills
Households struggling with rising energy costs may be eligible for financial support, including:
- British Gas Energy Trust – up to £2,000 in debt relief
- Household Support Fund – council-issued grants or vouchers
- Cold Weather Payments – £25 for each seven-day cold spell
- Warm Home Discount – £150 off energy bills
Eligibility varies depending on income, benefits, and location.
Why This Warning Matters
With freezing temperatures expected to persist, British Gas says early action could prevent thousands of households from facing emergency repairs, water damage, or prolonged heating outages. Engineers stress that simple steps taken now could save hundreds, or even thousands, of pounds later.
FAQ
Why has British Gas issued a warning this week?
British Gas expects a surge in boiler and heating failures as freezing temperatures increase the risk of frozen and burst pipes across the UK.
How many homes are affected by the British Gas warning?
At least 54,000 households are expected to need help with heating or hot water systems during the cold snap.
What temperature should I set my heating to prevent frozen pipes?
British Gas recommends keeping heating set to a minimum of 7°C, even when you are away from home.
What is a frozen condensate pipe?
It’s a pipe that removes waste water from modern boilers. In freezing weather, it can ice over, causing the boiler to shut down.
What should I do if my boiler stops working in cold weather?
Check for frozen pipes, thaw safely using hot water, reset the boiler, and call an engineer if the issue persists.
How can I stop my pipes from freezing?
Lag exposed pipes, use frost protection settings, seal draughts, and maintain low-level heating during cold spells.
Is financial help available for heating costs?
Yes. Support includes the British Gas Energy Trust, Cold Weather Payments, Warm Home Discount, and council grants.
