As energy costs rise, a few smart tweaks—plus a couple of targeted upgrades—can significantly lower your bills without sacrificing comfort.

1. Improve Your Heating Setup
- Lower your boiler’s flow temperature to around 50–55 °C—this can save up to £700 per year.
- Install thermostatic radiator valves (TRVs) and a programmable or smart thermostat to heat rooms individually and only when needed.
- Get an annual boiler service for efficient performance and lasting reliability.
2. Enhance Insulation and Brush Up Draught-Proofing
- Aim for 270 mm of loft insulation; combined with wall insulation, this can save £150–£600 annually.
- Seal gaps around doors, windows, and floors—professional draught-proofing costs around £250 with about £80 annual savings; DIY options offer great value.
3. Install a Smart Meter
- Free to install, smart meters eliminate estimated billing and provide real-time usage data.
- Typical savings: ~3% on electricity and ~2.2% on gas, equating to around £50 per year.
4. Upgrade to Energy-Efficient Appliances & Lighting
- Swap out old appliances for A-rated models to cut electricity usage noticeably.
- Switch all lighting to LEDs—use 75–90% less energy—and add smart or motion-sensing controls to eliminate waste.
5. Cut Phantom Power & Use Smart Plugs
- Devices on standby can account for 9–16% of electricity usage.
- Smart plugs or fully switching off appliances can recoup £50–£100 annually in savings.
6. Optimise Appliance Usage
- Wash clothes at 30 °C and only when full; skip tumble drying—air-dry instead.
- Use lids on pots, short showers (4–5 min), and avoid over-filling kettles to reduce energy use without changing routines.
7. Use Off-Peak & Green Tariffs
- Switch to cheaper or flexible tariffs like Economy 7/10 or agile smart plans—running appliances overnight could save hundreds annually.
- Those with solar PV should secure a Smart Export Guarantee to earn from unused generation.
