Despite being the most expensive place to live for property prices, London homes are the most energy efficient and require the least spending on bills, home improvement and energy efficient website Everest has found.
London has the majority of A- and B Energy Performance Certificate (EPCs). Tower Hamlets, Greenwich and City of London topped the chart as the three most energy efficient areas according to the data.
Some 29% of Tower Hamlet properties received an A- or B-rated EPC – which is the highest across the country, followed by Greenwich and City of London with 20% retrospectively. There has been significant investment in London and Tower Hamlets specifically from local governments.
Despite being one of the most economically disadvantaged areas of the UK, Tower Hamlets has been part of The London Plan and London Climate Change Action Plan.
Because of this, Tower Hamlets and areas surrounding the capital have the highest EPC ratings.
When looking outside of London, Dartford (Kent), Uttlesford (Essex), and Basingstoke and Deane (Hampshire) are amongst the top 10 best areas with the most top rated EPCs.
Homes with an A- or B-rated EPC spend on average £1,104 on their energy bills over three years. And those that are benefiting from cheaper bills are situated within or near the capital. However, the data shows that just 19,832 dwellings benefit from an A- or B-rated EPC.
Most dwellings have a D rating that has energy costs, on average, of £3,228 across three years.
There are 6.36 million dwellings in England Wales with an average D-rated EPC. However, the problem lies amongst the lowest rated homes.
Some 1.04 million dwellings across the country received an F- or G-rated EPC making them the least energy efficient houses in England and Wales. Those living within these homes are paying on average £5,743.50 for their energy bills across three years – 3.5 times more than those with an A- or B-rated EPC.
Isles of Scilly, Gwynedd, and Ceredigion are the three worst areas. A huge 35% of properties within the Isles of Scilly received an F- or G-rated EPC – the worst grade possible.
Most properties across the west fringes of the country are not suitable for cavity wall insulation due to the fact they are highly exposed to wind and driven rain. This can cause problems with damp and mould in the walls and affecting the health of homeowners living in the dwelling.
