Property expert Phil Spencer has teamed up with Wickes to share five budget-friendly home insulation hacks that could save households up to £108 on their energy bills this winter.
The tips come as a Citizens Advice study from 2026 found that more than 10 million households — equivalent to 37% of people across Britain — are concerned about meeting their energy bills. The study also revealed that 28% of prepayment meter users ran out of gas and electricity in the past year because they could not afford to top up.
Insulate Hot Water Tanks and Pipes
Spencer highlighted that poorly insulated hot water cylinders "waste significant energy." He said: "In fact, homeowners could save a further £45 a year by upgrading from 25mm of insulation to an 80mm jacket." He described this as a "simple, low-cost fix" at around £25 that could "pay for itself within the first year while helping keep heat where it's needed."
Exposed pipes in unheated spaces are another culprit. Spencer warned: "Exposed hot water pipes in lofts, garages and other unheated spaces can lose heat and are vulnerable to freezing during cold snaps. Adding suitable pipe lagging can help reduce heat loss and protect pipework." Wickes stocks pipe insulation from as little as £1.
Cover Chimneys and Use Radiators Correctly
Spencer noted that open chimneys "allow warm air to escape" when a fireplace is not in use. He explained: "According to the Energy Saving Trust, chimney draught-proofing could save around £45 annually." A chimney draught excluder is the recommended solution.
He also stressed the importance of not "heating walls instead of rooms," warning that "radiators positioned against poorly insulated external walls can lose heat through the wall behind them." Fitting reflector panels can "help direct warmth back into the room, potentially saving around £18 annually."
Check Your Loft Hatch
Even a well-insulated loft can lose heat through gaps around its hatch. Spencer advised ensuring it fits snugly, applying appropriate draught-proofing, and insulating the hatch where necessary.
He said: "My advice is to start by looking at where warmth might be escaping and tackle the smaller jobs first. Making a few practical improvements can help keep your home more comfortable during the colder months, without necessarily spending a fortune."
