The bulk of insulation grants are awarded to homes that emit the largest amount of carbon. Electric Heated Properties are Preferred.

Detached houses & Electric Heated Properties are given priority at the expense of the smaller ones who usually will not get any insulation due to the cherry picking of installers working on the scheme.

Grants For External / Internal Wall Insulation 



Properties that have a solid walls may be suitable for both internal wall and external wall insulation.

This involves fixing foam or insulated plasterboard to the walls and then rendering / plastering.

As these are both very expensive (£5000 – £12000) the grants are usually awarded to electric properties that save the most carbon.

Saves £490 a year on bills. Average cost £75 -£100 per metre2.

An average semi detached property will cost £8000 – £1000 to insulate.

Gas heated properties are very unlikely to get a grant towards these measures as the funding is very low. However electric heated properties can apply as their carbon savings are very high and in most cases it will be fully funded.



Free Grant For Loft Insulation


Saves you up to £150 per year.

Average cost £15- £20 per roll .   Diy costs around £180 per average loft
Professionally will cost you on average £400- £500

The grant covers the loft insulation material and installation.

To qualify your property must have no loft insulation at all, or the existing must be less than 100mm thickness of loft insulation.



Free Grant For Underfloor Insulation


A small amount of heat is lost whatever floor type you have, be it concrete or suspended wooden floor. Insulating your floors should save you around £50 per year in heat savings. Whilst it is a very small saving, it is very much worthwhile.

·   This involves insulating the space below the flooring and will involve taking up the floor for access.

You don’t need to insulate the floors of upstairs rooms in your house if they’re above heated spaces, such as the living room.

Rooms above unheated garages do need to be insulated.

Rugs and carpets on the floor will also help your feet feel warmer, which might mean you don’t feel the need to put the heating on as much.    Saves you £60 per year

Average cost £15 -£20 per roll   – Diy cost around £100 per room.


Should You Insulate all Floors ?



Old suspended wooden floors can be very draughty and insulating them will save you up to £50 a year on lost heating.

These Timber floors can be insulated by lifting the floorboards and laying mineral wool insulation supported by netting between the joists. Average room will need 3-4 rolls of insulation and cost will be around £15 -£20 per roll depending on thickness.

You can also use foam board such as Kingspan.
Remember to seal  the Gaps and draughts around the  skirting boards and floors too  with a tube of sealant bought from any DIY store.

Wooden floors will have air bricks in your walls, so take care not to block them up. They are needed to help ventilate the space under your floor and stop your floorboards rotting.


Concrete floors


loft insulation

New houses will have a ground floor made of solid concrete.
Solid floors are insulated using rigid insulation foam, which can be fitted either above or below the concrete.
This will raise the level of the floor, so you will need to       Trim doors  down. ·         Move skirting boards and some electrical sockets.
If the concrete is above the insulation it can store heat during the day, which helps to keep the room warm at night. If the insulation is above the concrete the room will heat up more quickly in the morning.

You have to insulate a solid floor when it is replaced in order to comply with building regulations. The finished floor should achieve a U-value of 0.25 W/m2K or less. 



Free Grant For Cavity Wall Insulation



The most popular type of insulation obtained through the ECO grant is cavity wall insulation.

This cavity between the walls is filled with an insulating material (usually rockwool or bead) which serves as a barrier to allowing the heat to escape through the walls.

Cavity wall insulation usually costs around £20 per m2 and you can expect to pay around £1200 for an average semi if you pay privately.


What are Cavity Walls

Houses built from the 1930s onwards usually have a 1 -3 inch cavity in between the outside and inside wall.

Walls were built this way to stop damp from penetrating the house so that any moisture penetration would drop into the cavity harmlessly.

You can easily tell if your home has cavity walls by measuring their width by the windows or doors.

A solid wall will measure below 260 mm and a cavity wall is usually around 300 mm.


Properties Not Suitable For cavity wall insulation

  • timber framed,
  • metal framed
  • stone properties
  • solid wall
  • flats – permission must be sought by all of the adjoining properties that share the cavity walls
