10 hidden places to fix in your home to cut heating bill

While the summer brings warmer weather, many people will likely be tempted to forget about potential heating issues.

However, this could be the perfect time to address them before the colder temperatures return in the winter.

Gordon Wallis, at heating oil suppliers Your NRG, says tackling these problems in the summer helps avoid unexpected costs when energy use ramps up again towards the end of the year.

While turning your thermostat down by 1°C can save over £100 a year, Mr Wallis says the first step should be fixing draughts that cause heat loss.

The 10 hidden places you need to fix now to cut your heating bill

Doors (internal and external)

Mr Wallis explains: “Poorly sealed doors let warm air out in winter — and can cause your home to overheat in summer too."

Add draught excluders and weatherstripping to create a tighter seal

Keyholes

While external keyholes are small, they can let in more air than you think, so a simple keyhole cover can block airflow effectively.

Windows

Old and single-glazed windows can let heat through, but silicone sealant or foam tape can seal the edges.

Alternatively, you could upgrade your windows to double-glazing.

Floors and skirting boards

Timber flooring and wall junctions are prone to tiny gaps. Use flexible filler in floorboards and caulk along the base of skirting boards.

Pet doors

Loose or warped flaps can cause constant draughts, so consider upgrading to insulated or magnetic flaps.

Alternatively, you could temporarily block them during colder months if not in use.

Chimneys

Chimneys can act like funnels for cold air, so Mr Wallis advises to use a chimney balloon or a removable draught excluder to block the airflow.

These can also be easily removed when needed.

Recessed lighting

Downlights can create ceiling gaps, so install IC-rated lighting and seal edges with fire-rated caulk to prevent air leakage.

Loft hatches and roof space

Mr Wallis says: "Insulating your loft hatch and sealing gaps in the roof prevents heat escaping in winter and improves comfort all year round."

Pipes and cables

Pipes running through exterior walls often leave draughty gaps. Fill them using expanding foam or silicone sealant.

Ventilation systems

“Extractor fans and air bricks should be fitted with backdraft shutters or vent covers that balance airflow without letting in cold air," Mr Wallis shares.

He added: “Even when the sun’s shining, energy efficiency should be on the agenda.

“What you do now can protect your finances — and keep your home warmer — when winter comes around again.”
