Your 3-step plan to lower energy bills

We prioritise the highest impact upgrades first, then optimise the rest.

Step 1

Assess

A quick review of your home’s insulation, heating system, controls, and usage patterns to identify where energy is lost.

Step 2

Optimise

Set boiler flow to an efficient temperature, tune controls, switch to suitable tariffs, and tackle draughts and lighting.

Step 3

Upgrade

Plan fabric and system upgrades—loft/wall insulation, smart thermostats, solar PV, heat pumps—supported by available grants.

Top ways to cut home energy costs

Start with quick wins, then move to the bigger, longer-term improvements.

1) Insulation and draught-proofing

  • Loft insulation to the recommended depth where appropriate; top up thin insulation in older homes.
  • Cavity wall insulation if your property type is suitable; consider internal/external options for solid walls.
  • Draught-proof around doors, letterboxes, chimneys not in use, and loft hatches.
  • Insulate hot water cylinders and primary pipework to reduce heat loss.

2) Heating controls that work for you

  • Lower your boiler flow temperature to a comfortable, efficient setting (often around 55–60°C for condensing boilers).
  • Use programmable schedules and thermostatic radiator valves to heat rooms only when needed.
  • Bleed radiators and balance the system to ensure even heat distribution.
  • Service boilers annually for safety and efficiency.

3) Hot water and appliances

  • Set your hot water cylinder thermostat to around 60°C and use timers to avoid overheating water.
  • Choose A-rated appliances when replacing; use eco modes and lower temperature washes.
  • Switch to LED lighting throughout; fit occupancy sensors where suitable.

4) Smart meters and tariffs

  • Request a smart meter to track usage in real time and spot wasted energy.
  • Consider time-of-use tariffs if you can shift demand (e.g., laundry or EV charging off-peak).
  • Review fixed vs. variable tariffs in line with the Ofgem price cap and your risk tolerance.

5) Renewable options

  • Solar PV can offset daytime electricity use; pair with battery storage to increase self-consumption.
  • Heat pumps work best in well-insulated homes with low-temperature heating; check eligibility for grants.

Room-by-room quick wins

Living areas

  • Close curtains at dusk; use thermal linings.
  • Seal floorboard gaps; use rugs on bare floors.
  • Avoid blocking radiators with furniture.

Kitchen

  • Use lids on pans; match hob size to pan.
  • Air-dry when possible; keep fridge seals clean and tight.
  • Only boil the water you need.

Bathroom

  • Fit water-saving shower heads.
  • Use extractor fans efficiently to reduce moisture, not heat.
  • Fix dripping taps to cut hot water waste.

Bedrooms & loft

  • Top up loft insulation and insulate hatch covers.
  • Use TRVs to set lower temperatures for sleeping comfort.
  • Eliminate draughts around windows and eaves storage.

Before you upgrade

  • Review your EPC and previous bills to benchmark use.
  • Prioritise fabric (insulation) before new heating systems.
  • Confirm installer accreditations and warranties.

FAQs: Home energy savings in the UK

Straight answers to the most common questions we hear.

Savings vary by property size, insulation levels, and behaviour. Quick adjustments (flow temperature, schedules, LED lighting, draught-proofing) often deliver noticeable reductions, while insulation and heating upgrades can add significant long-term savings. We’ll estimate ranges for your home during your free check.

For most homes, heating only when needed with correct schedules is more efficient than leaving it on constantly. Well-insulated homes with low-temperature systems may operate efficiently for longer periods. Your property’s insulation and system type determine the best approach—we’ll tailor advice to you.

Many condensing boilers operate most efficiently at lower flow temperatures, often around 55–60°C. Comfort, radiator sizing and hot water needs matter—start at an efficient setting and adjust if rooms don’t reach temperature. Always follow your manufacturer’s guidance.

Smart meters help you understand usage in real time and access more tariff options, including time-of-use. They don’t save energy by themselves, but they make it easier to spot waste and shift usage, which can reduce bills when paired with action.

These programmes support eligible households with insulation and efficiency upgrades. Criteria depend on income, property type and local availability. We’ll check your circumstances and explain what support could apply, then help you take the next steps.

Solar PV suits properties with usable roof space and daytime electricity use; batteries increase self-consumption. Heat pumps perform best in well-insulated homes with low-temperature emitters. We’ll assess your property and advise on suitability, cost and potential support.
