Millions of homes have an “isolation age” of 1976 or older — costing homeowners hundreds

Less than one in ten UK households have installed insulation in the last 20 years – and homeowners could be paying almost £1,000 a year if they don’t make changes

According to a study, millions of homes have an insulation age of 1976 or older – costing households up to £930 a year if they don’t make changes soon.

Experts analyzing 21 million homes across England and Wales found that over half (58%) only met insulation standards from 1976 or earlier.

As a result, they lose more heat through cavity insulation, double glazing, attic insulation and floor insulation than modern regulations require today.

Around 1.6 million objects (7.5%) have an insulation age of 2002 or younger, and only 4,663 have an insulation age of 2013.

But the average semi-detached homeowner could save up to £285 a year by upgrading their cavity wall insulation and a further £255 by having a well-insulated attic.

Energy bills for these residents could also be reduced by a further £390 a year if they renewed their solid wall insulation.

The study, conducted by EDF in partnership with real estate data platform Sprift, analyzed the current state of home insulation – including the floor, roof, window and wall – against the building codes of homes over various time periods to determine the country’s “age of home insulation”. to calculate “.

It comes after additional research of 2,000 homeowners commissioned by EDF found that only 37% have ever renewed their property’s insulation.

A quarter (25%) didn’t because it was too expensive, while one in five (19%) would rather spend their money on other things.

And 17% don’t know what kind of insulation they would even need.

Philippe Commaret, Managing Director for Customers at EDF, which has announced it will spend an extra £20m this year on energy efficiency measures for fuel-efficient homes, said: “It is surprising that the average insulation age of a home is over 40 years, with so few homes that have installed sufficient insulation to meet modern energy efficiency standards.”

Jade Lewis, Chief Executive of the Sustainable Energy Association, added: “Energy efficiency is a key enabler of our nation’s transition to Net Zero – for too long many UK homes have been poorly insulated and heated.

“These inefficient buildings not only impede our progress toward net-zero, but also our energy security, the health and well-being of our nation, and contribute to energy poverty, which will only increase if we weather the storm of our current energy crisis.

“SEA believes now is the time to invest in healthier buildings, reducing greenhouse gas emissions and lowering their operating costs, and we will continue to support initiatives like EDF’s that make this a reality.”

The study also found that one in five homeowners (21%) has no idea how to insulate buildings to improve their energy efficiency.

However, two-thirds (65%) of those who have thought about or renewed their home’s insulation acknowledge that it helps save on energy bills.

Research conducted via Onepoll also revealed that two-thirds were unaware of the EPC rating of their current property.

But nearly half (43%) have made or considered upgrading the energy efficiency of their home for the good of the planet.

Philippe Commaret added: “As energy prices continue to rise, quality insulation is the most effective way to permanently reduce household bills – but this is often overlooked as installation costs are a significant barrier for many.

“That’s why it’s so important that we work with government and industry to find new ways to insulate more homes as quickly as possible, and that’s why we will support our vulnerable customers to insulate their homes now, before.” the bills will go up again in October.”
