Improve roof insulation
About 25% of a home’s heat escapes through the roof. Adding the recommended loft insulation can cut your bills significantly—up to £380 a year in a detached home.
Install a carbon monoxide alarm
CO risks rise in winter. If you don’t have an alarm, buy one for around £15 (look for EN 50291-1). Make sure boilers and heaters are serviced regularly.
Insulate exposed water pipes
Pipes in lofts or unheated spaces can freeze and burst. Fit inexpensive pipe lagging to prevent damage and costly repairs.
Insulate your hot water tank
A proper hot water tank jacket costs under £20 and can save around £40 a year by keeping water hotter for longer.
Clear your gutters
Blocked gutters cause damp, mould and can crack when water freezes. Clear leaves and debris or use a gutter brush to prevent blockages.
Consider a smart meter
Smart meters help you track energy use in real time and spot waste. They’re free to install—just request one from your supplier.
Bleed your radiators
If radiators are cold at the top, trapped air is stopping them from heating properly. Bleeding them improves efficiency and warmth.
Use heavier curtains and draught excluders
Thick curtains, rugs and door draught stoppers help keep heat in and cold air out. Open curtains during the day to let natural heat in.
Check your boiler
Service your boiler annually and check the pressure before winter. Fixing small issues early can prevent breakdowns and avoid expensive replacements.
Stop heat escaping up the chimney
If you don’t use your fireplace, use a chimney balloon or draught stopper to reduce heat loss and cold drafts.
