As freezing temperatures grip the UK this winter, many households worry about rising energy costs. A recent survey of 2,000 consumers shows that nine in 10 fear affording their bills, with two-thirds limiting heat to one room to save money.
Experts at Energy House 2.0, the UK’s leading energy research facility at the University of Salford, conducted an 18-month study on heating systems. Collaborating with property developers, the team tested methods to warm homes efficiently while minimizing costs. Their findings highlight practical steps, from quick fixes to long-term investments, to reduce energy use without major expenses.
The Top Free Method: Lower Your Boiler’s Flow Temperature
The study identifies lowering the boiler’s flow temperature as the most effective no-cost strategy to slash heating bills. This setting controls the water temperature leaving the boiler for radiators, typically ranging from 70°C to 80°C in standard systems.
Researchers found that dropping the temperature from 80°C to 60°C cuts gas consumption for heating by 12%. Combi-boilers perform well at 60°C, providing steady warmth without excessive energy use. While radiators may feel less hot and rooms take slightly longer to heat, well-insulated homes maintain comfort with significant savings.
To adjust, locate the dial or buttons with a radiator symbol on combi-boilers and lower the setting. Consult the manual for specific instructions. This simple change requires no tools or investment.
Ensure Boiler Efficiency with Regular Servicing
The boiler remains a vital home appliance for hot water and heating. Annual servicing ensures safety, upholds warranties, and boosts efficiency. Schedule it in summer to avoid peak winter demand.
If radiators heat unevenly or issues arise, a service costs around £90. Engineers inspect components, filters, flues, and check for leaks or corrosion. They also verify efficiency; even a 5% drop can add £87 to annual bills. Professionals can adjust flow temperatures during visits if needed.
Boost Insulation to Trap Heat
Proper insulation prevents heat loss through walls and roofs, especially in older homes. Pre-1920s properties often lack wall insulation, leading to higher bills. New builds comply with regulations and use up to 65% less energy.
Oliver Novakovic, innovation chief at Barratt Redrow, notes, “The large number of poorly insulated, older homes across the country can cause stress for those living in them as we approach winter.” Official data indicates 60% of English homes have average or better wall insulation, rising to 69% in Scotland and 52% in Wales.
For lofts, mineral wool insulation suits detached homes at about £1,000. It yields £340 annual savings for detached properties and £200 for semi-detached ones. These upgrades pay off over time by retaining warmth.
Seal Draughts for Controlled Ventilation
Draught-proofing targets air leaks without blocking all airflow, which risks condensation and mould in kitchens or bathrooms. Novakovic advises, “Try to locate draughty areas around your home so that you can fix them before the freezing temperatures set in.”
A smoke pencil draught detector, costing under £50, pinpoints leaks easily. Older hardwood doors expand and contract, widening gaps; add draught excluders or gap sealers. Focus on letterboxes, chimneys, doors, windows, and loft hatches.
Weather stripping in foam, rubber, or metal fits window frames simply. For UPVC windows, inspect existing excluders for damage. This maintains ventilation while blocking cold air.
Use Curtains and Blinds to Insulate Windows
Closing curtains or blinds reduces heat loss through windows by 10-30%, particularly in single-glazed older homes. They trap a layer of still air, acting as extra insulation—no special thermal types needed.
The research shows radiators under windows lose more heat as warm air rises and escapes. Curtains mitigate this, cutting draughts and condensation too. As affordable and easy options, they suit homes where full window upgrades aren’t possible.
Explore Efficient Electric Heating Options
With gas boilers phasing out, the study tested electric alternatives like infrared panels, air source heat pumps, underfloor, and skirting heating. Air source heat pumps emerge as efficient, costing £1.84 daily in winter to heat a typical home—better than gas for steady temperatures.
Prevent Frozen Pipes with Insulation
Freezing pipes expand and burst, causing costly repairs. Insulate loft pipes and water tanks to avoid this. Novakovic explains, “Insulating your pipes doesn’t have to be expensive and can be done as a DIY job. You can buy foam pipe insulation, which is inexpensive, though better-quality insulators will set you back more.”
Foam tubes slip over pipes; wraps handle bends. Measure pipes first and avoid flammable materials. These steps protect against winter damage affordably.
The consumer survey underscores widespread adoption of these practices, emphasizing their role in easing winter energy pressures.
