'I'm an expert - this simple 2-minute loft insulation move could save you £300 in 2025'

An expert has shared how a two-minute insulation hack could help Brits to save £300 in 2025.

Experts at Gaffsy said that as millions of households are putting Christmas decorations back in the loft this week, there is no better time to make sure that the house is properly insulated.

The advice comes as the Met Office issued a yellow weather warning for snow and ice across the UK this week.

According to the experts, checking the loft insulation could save up to £300 annually on energy bills.

It is because if the top of the house isn't properly insulated, you will lose up to 25% of heat through the roof, they warned.

The telltale sign your loft is not properly insulated (that even your neighbours can see) is to look up at your roof from outside your home on a frosty or snowy day.

They said: "If frost or snow covers your roof evenly, that is a sign that your roof is properly insulated.

"If the frost/snow coverage is patchy and sparse, that is usually an indication that heat is escaping through your roof. This could lead to energy loss and higher heating costs."

The experts explained that there are three main ways to check on the quality of your insulation: "The recommended thickness of loft insulation is 270mm. If your insulation falls short of this, it is advised that you add more layers to reach the recommended depth.

"The main things you should look for when checking your roof insulation are mould, moisture and holes. If these signs are present on your insulation, it is advisable to replace it.

"Insulation materials deteriorate over time so if your insulation is more than 20-30 years old, it may need replacing, as newer materials are more efficient."

Oren Kander, senior valuer and director at Gaffsy, said: "Many homeowners don't realise that the condition of their roof on a frosty morning can reveal a lot about their home's energy efficiency.

"Uneven frost or snow melt indicates that heat is escaping, which not only drives up energy bills but also decreases your home's temperature.

"By addressing insulation issues early, you can prevent significant heat loss, improve your home's energy efficiency, and make substantial savings on your heating costs. It's a simple observation that can make a big difference."
