Home Energy Efficiency in the United Kingdom
Cut your energy bills, increase comfort, and lower your carbon footprint with proven upgrades designed for UK homes. From quick wins to whole-home retrofits, our experts make it simple.
Why improve energy efficiency now?
UK households face rising energy costs and increasingly variable weather. Investing in energy efficiency protects your budget, boosts your EPC rating, and makes homes healthier and more comfortable year-round. Whether you own, rent, or manage property, targeted upgrades can reduce wasted heat and deliver measurable savings.
Lower energy bills
Stop heat loss with insulation, efficient heating, and smarter controls. Many households can save hundreds of pounds per year with the right measures.
Improved EPC rating
Raise your property’s EPC score for better comfort and potential valuation benefits. Helpful for future-proofing and regulatory compliance.
Lower carbon footprint
Efficient homes use less energy. Choose insulation, renewables, and low-carbon heating to cut emissions without compromising comfort.
The most effective home upgrades for UK properties
Every home is different. We survey your property fabric, heating system, and usage to identify the best-value upgrades—prioritising insulation and air-tightness before tackling heating and renewables. Here are the measures that deliver consistently strong results in the UK climate:
- Loft and roof insulation – Often the biggest quick win. Top up to recommended depths to reduce heat loss significantly.
- Cavity wall insulation – For suitable properties, fills the gap between walls to retain warmth.
- Solid wall insulation – Internal or external systems for older or solid-wall homes.
- Floor insulation – Insulate suspended timber floors and key thermal bridges.
- High-performance glazing – Double or triple glazing, plus draught-proofing and quality seals.
- Efficient heating – Consider heat pumps, high-efficiency boilers, and zoning for better control.
- Smart controls – Smart thermostats and TRVs avoid overheating rooms and reduce wastage.
- Renewables – Solar PV and battery storage can offset electricity costs and improve EPC ratings.
- Ventilation with heat recovery (MVHR) – Keeps indoor air fresh while retaining heat in highly insulated homes.

What savings can I expect?
Savings depend on your property type, current insulation, and heating system. Typical examples for UK homes:
- Loft insulation top-up: noticeable comfort boost and significant reduction in heat loss.
- Cavity wall insulation: strong payback in suitable properties.
- Smart heating controls: more precise control can cut unnecessary heating time.
- Air source heat pump + insulation: major carbon cuts and stable running costs when designed correctly.
- Solar PV: generates your own electricity, with further benefits when paired with battery storage.
We provide clear estimates during your survey, so you know expected savings, costs, and timescales before you proceed.

Room-by-room tips you can act on today
Whole home
- Draught-proof doors, letterboxes, and loft hatches.
- Use smart schedules and set thermostats to a comfortable but efficient level.
- Seal gaps around pipes and floorboards where safe and appropriate.
Loft & walls
- Check insulation depth in the loft and avoid compressing it with storage.
- Consider cavity or solid wall insulation for significant heat retention.
Heating & hot water
- Bleed radiators and balance your system for even heat distribution.
- Fit thermostatic radiator valves (TRVs) and smart controls.
- Add cylinder insulation and pipe lagging where appropriate.
Windows & doors
- Upgrade to efficient glazing; add secondary glazing in period properties.
- Use quality seals and curtains with thermal lining.
