SOME families are seeing up to 30 per cent of their energy bill “go straight out of the window” because of a lack of insulation, Citizens Advice has warned.

The advisory service said many families will continue to struggle with high energy costs and cold, damp homes despite the recently announced bill freeze due to a lack of investment in basic cost-saving measures like insulation.

The Government’s freeze on energy prices means the average bill will be £2,500 a year from October 1.

However, Citizens Advice said more than a million people living in homes with an energy performance certificate (EPC) rating of F will face an average bill of more than £3,000.

In Flintshire and Wrexham, there are thousands of homes which have been described as "energy crisis hotspots" as they require cavity wall insulation.

Furthermore, draughty and inefficient homes mean they will lose £950 worth of the heat they pay for through the walls, windows and roof, it warned.

Currently, the majority of homes in England and Wales are below this standard, a significant proportion being pre-war buildings.

There are also regional disparities, with people living in Wales, the West Midlands, and Yorkshire and the Humber facing the highest costs, Citizens Advice said.

Almost two thirds (63 per cent) of homes in these areas have EPC ratings below band C.

Households in London and the South East are most likely to be in a better position, but more than 50 per cent of homes in these regions still have poor EPC ratings.

Rich Jones, energy projects manager at Citizens Advice, said: “Most of the people we advise are disabled or have a long-term health condition. One person we’ve spoken to is relying on her son to do her washing by hand to save on electricity.

“She says she’s cold all the time. Several parents have told us their children’s bedrooms are so damp that they’ve given them their room and are now sleeping on the sofa or floor instead.

“Grants, budgeting and benefit checks can only provide some short-term relief. But improving their homes would make a big difference.”

Citizens Advice chief executive Dame Clare Moriarty said: “The Government’s bill freeze puts an emergency stop to terrifying price hikes. Now we need an exit strategy from this energy crisis.

“Bills are going through the roof – literally for people in cold and draughty homes, where heat seeps out when they turn up the thermostat. This is burning through many people’s tight budgets.

“Insulating our homes is the long-term solution that will cut down our bills and reduce our dependence on gas. The government must make it a top priority.”

Since 2009/10 to the end of March 2021, the Welsh Government has invested more than £394m to improve home energy efficiency through the Warm Homes Programme (Nest), benefitting more than 67,100 lower income households.

The programme offers a range of free, impartial advice to all homes in Wales and a package of free home energy efficiency improvements following recommendations of a whole house assessment where the eligibility criteria is met. 

A Welsh Government spokesperson said: "Improving the energy efficiency of homes is the most effective way we can support householders to reduce their energy bills. More than 67,000 lower income homes have benefitted from our £394m Warm Homes programme over the last 10 years and we are currently developing the next phase of the programme.

“This winter, we are expanding our Winter Fuel Support Scheme, which will provide a £200 payment to some 400,000 households to help them pay their energy bills.”
