UK household energy bills remain well above pre-2021 levels. Here's how to reduce what you pay.
Understanding Your Bill
Your bill has two parts: a standing charge (~60p/day electricity, ~30p/day gas) and a unit rate (cost per kWh used). Ofgem's price cap limits the maximum rate — not your total bill.
Most Effective Savings
Insulation — Biggest Impact
Loft insulation saves £300+/year. Cavity wall insulation, £250+/year. Draught-proofing, ~£50/year and easy DIY.
Boiler Flow Temperature
Turning your boiler flow temperature from 80°C to 60°C reduces gas consumption by 6–8% with no comfort loss.
Smart Thermostat
Hive, Tado or Nest typically saves £100–150/year.
Key TakeawaySmart meter awareness + insulation + thermostat optimisation can realistically save £400–700/year — more than most tariff switching alone.
