"London dominates the leaderboard due to the volume of modern developments, but improving the older housing stock remains a bigger, more complex challenge"
- Hugh Gibbs - Searchland
New analysis from Searchland has identified the parts of Great Britain with the most energy-efficient homes, based on average EPC ratings, with the City of London and Peterborough leading the way.
Searchland reviewed EPC data across all Local Planning Authority areas to find where buyers can minimise both their carbon footprint and household energy costs.
Regeneration projects set the pace
Only three LPAs boast an average EPC rating above C, all of which are major regeneration or new town development zones. They are Ebbsfleet Garden City: Average EPC score of 84/100, rating B, Old Oak and Park Royal (West London): 81/100, rating B, and Queen Elizabeth Olympic Park (East London): 80/100, rating B.
These large-scale developments are setting a new benchmark for energy efficiency, thanks to modern building standards and sustainability targets.
Top 10 energy-efficient non-regeneration areas
Beyond these regeneration hotspots, no LPA has an average rating above C. However, the most energy-efficient established areas are:
City of London and Peterborough (76/100)
Tower Hamlets (75)
Hackney (73)
Westminster, Greenwich, Southwark, Crawley, and Milton Keynes (all 71)
Bath & North East Somerset (70)
All of these locations maintain an average EPC rating of C, making them attractive options for energy-conscious buyers.
Where efficiency meets affordability
Of the top energy-efficient areas, Peterborough offers the most affordable homes, with an average price of £232,299. Other comparatively affordable options include Crawley (£324,823), Milton Keynes (£329,196), and Bath & North East Somerset (£409,166).
Meanwhile, while efficient, London boroughs such as Greenwich, Westminster, and Southwark demand significantly higher property prices, often exceeding £500,000.
The least energy-efficient areas
At the other end of the scale, six LPA areas recorded an average EPC rating of E, including:
Yorkshire Dales National Park (46)
Snowdonia National Park (48)
North York Moors National Park (49)
Exmoor National Park (52)
Na h-Eileanan Siar (53)
Northumberland National Park (53)
These areas typically feature older, protected housing stock where modernisation is limited.
Hugh Gibbs, Co-Founder of Searchland, Comments: “Energy efficiency is being driven by the new-build sector, particularly through major regeneration projects. London dominates the leaderboard due to the volume of modern developments, but improving the older housing stock remains a bigger, more complex challenge. True progress will depend not just on developers but also on the willingness of homeowners to upgrade their properties.”
