Free Insulation Grant
Insulation Grants for UK Households
Looking for insulation grants? Funding has now closed, but there are still ways to improve your home, reduce heat loss, and prepare for future support.
Will Free Insulation Grants Return?
While schemes such as ECO4 and GBIS have now closed, insulation is still a key part of the government’s long-term plans to improve energy efficiency across UK homes.
Future support is expected to come through the Warm Homes Plan, a £15 billion programme designed to fund home upgrades over the coming years. This will replace previous schemes and take a broader approach, focusing on improving how homes perform overall rather than funding single measures in isolation.
What the Warm Homes Plan Is Expected to Include
Insulation is expected to remain a central part of the scheme, with support likely to cover:
External or internal wall insulation
Loft and room-in-roof insulation
Cavity wall insulation
Underfloor insulation
The aim is to address the areas where the most heat is lost, helping your home retain warmth more effectively and reduce ongoing energy use.
Who Is Likely to Qualify
Support is expected to be prioritised for:
Homes with EPC ratings of D, E, F or G
Properties that are expensive to heat
Households that may struggle to fund upgrades upfront
Funding could be available up to £15,000 depending on the property and the level of improvement required.
Why Insulation Still Makes Sense Without a Grant
Even without grant funding, insulation remains one of the most effective ways to reduce energy loss in your home. It works immediately, helping your home retain heat and reducing how much your heating system needs to run.
Without insulation, you’re constantly paying to replace heat your home can’t retain. With it, your home starts holding onto that warmth, reducing waste, lowering costs, and improving comfort day after day.
-
1
Reduces Heat Loss at the Source
A significant portion of heat loss happens through the structure of your home:
Up to 25% through the roof
Around 30–35% through walls
Ongoing loss through floors and draughts
Insulation targets these areas directly, stopping heat from escaping and allowing your home to hold onto warmth for longer.
-
2
Cuts Ongoing Energy Costs
By reducing how much heat is lost, insulation lowers the amount of energy needed to keep your home warm.
Most households see savings in the region of £300 to £800 per year, depending on the property and the level of improvement. This saving repeats every year, rather than being a one-off reduction.

3
Reduces Reliance on Your Heating System
Without insulation, your boiler or heating system has to work continuously to replace lost heat.
With insulation in place, your system runs more efficiently:
less frequent heating cycles
lower overall energy demand
reduced wear over time
-
4
Creates a More Consistent Indoor Temperature
Insulation helps stabilise how heat moves through your home, reducing common issues such as:
cold rooms upstairs or downstairs
uneven temperatures between spaces
heat dropping quickly after the heating turns off
The result is a home that feels consistently warm, rather than fluctuating throughout the day.
-
5
Helps Prevent Damp and Condensation Issues
Poor insulation often leads to cold surfaces, which can cause condensation to build up over time. By improving how your home retains heat, insulation reduces the conditions that allow damp and mould to form, helping protect both the property and the indoor environment.
-
6
Improves Energy Efficiency and Property Value
Insulation contributes directly to your home’s EPC rating, which reflects how efficiently it uses energy.
A better EPC rating can:
make the property more attractive to buyers or tenants
support compliance for landlords
reflect lower ongoing running costs
What Insulation Can Be Installed in Your Home
The right type of insulation depends on how your home is built and where heat is being lost. The focus is on targeting the areas that will make the biggest difference, rather than installing everything unnecessarily.
Every property is different, which is why we don’t take a blanket approach. At Elite Energy, we assess where your home is actually losing heat and recommend the insulation that will make the biggest difference, based on your property, your usage, and what feels manageable for your budget.
Loft Insulation
Stops heat escaping through the roof, which is one of the biggest sources of energy loss in most homes. This is often the quickest way to reduce heating use and improve overall warmth.
Room-in-Roof Insulation
Designed for converted loft spaces, this helps retain heat in rooms that would otherwise lose warmth quickly through the roof. Improves comfort in attic bedrooms and upper floors.
Cavity Wall Insulation
Fills the gap within external walls to prevent heat escaping. Helps stabilise indoor temperatures and reduces how quickly rooms cool down once the heating is off.
Internal Wall Insulation
Applied to the inside of solid walls, reducing heat loss in properties without cavity walls. Helps improve how well rooms retain heat, particularly in older homes.
External Wall Insulation
Adds an insulating layer to the outside of the property, significantly reducing heat loss through solid walls. Can deliver a noticeable improvement in overall heat retention across the home.
Underfloor Insulation
Reduces draughts coming up from below and improves comfort across ground-floor rooms. Helps maintain a more consistent temperature, especially during colder months.
