Winter always brings a rise in energy use - and with that, a rise in energy bills. As heating engineers, we see firsthand how small changes can make a big difference to both comfort and cost. With a bit of planning and a few simple habits, you can keep your home warm without wasting energy.
Here are our top energy-saving tips for winter, based on what we recommend to our customers every day:
Service Your Boiler Before the Peak of Winter
A boiler that’s struggling will burn more energy to produce the same amount of heat.
A quick annual service ensures:
Better efficiency
Fewer breakdowns
Lower energy usage
Safer operation
A well-maintained boiler can save £££ over the winter
Bleed Your Radiators for Better Heat Output
If your radiators feel cold at the top but warm at the bottom, they may be full of trapped air.
This means your boiler works harder for less heat.
Bleeding your radiators:
improves heat distribution
reduces energy waste
keeps your home warmer, faster
It’s a simple job that makes a big difference.
Turn Down the Thermostat — Even by 1°C
Lowering your thermostat by just 1 degree can save up to 10% on heating costs.
Most homes stay perfectly comfortable around 18–19°C with proper insulation and warm clothing.
Try reducing it slightly and see how it feels - small changes add up.
Use Thermostatic Radiator Valves (TRVs)
Not every room needs the same temperature.
TRVs help regulate each radiator independently, meaning you can:
lower heat in unused rooms
keep bedrooms cooler
direct warmth where you actually need it
This avoids heating the whole home unnecessarily
Keep the Heat In – Insulation Is Key
Good insulation stops warm air escaping and reduces the strain on your heating system.
Check:
loft insulation
pipe lagging
draughty doors
leaky windows
cold spots around floors
Even simple fixes like draught excluders and thermal curtains help retain heat.
Make the Most of Timer Controls
Rather than having your heating on constantly, use a timer to match your routine:
warm the house just before you wake up
reduce heat while you're out
turn it down at night
Heating your home when you need it is far more energy-efficient.
Keep Internal Doors Shut
Rooms heat faster - and stay warm longer - when warm air is contained.
Closing doors, especially in larger or open-plan homes, helps your boiler work less and save more energy.
Don’t Block Radiators
Furniture pushed up against radiators absorbs heat instead of letting it circulate.
Move:
sofas
curtains
beds
cabinets
so the warm air can fill the room properly.
Use Your Boiler’s Eco Settings
Modern boilers often have an eco mode designed to reduce energy use without compromising comfort.
If your boiler has this option, it’s worth switching it on for more efficient performance.
Upgrade an Inefficient Boiler
If your boiler is old, noisy, or constantly breaking down, upgrading can drastically reduce your bills.
Newer boilers are:
more efficient
safer
cheaper to run
better for the environment
It’s an investment that pays back quickly in energy savings
Keeping your home warm over winter shouldn’t mean overspending. With a combination of good habits, proper maintenance, and smart use of heating controls, you can enjoy a comfortable home while keeping your energy bills under control.
