Roof Loft Insulation

There are many simple yet effective ways to insulate your home, which can significantly reduce heat loss while lowering your heating bills.

Roof & Loft Insulation

Heat rises, and in an uninsulated home, 25% of heat is lost through the roof. Insulating your loft, attic or flat roof is a simple and effective way to reduce heat loss and reduce your heating bills.
Cost (depends on house type): £300 – £400
Saving per year: £200 – £350 per year
Payback: Around 1-2 years.
Loft insulation is easy to install – you can even do it yourself. Even if you already have loft insulation, check its thickness. Adding another layer to bring it up to the recommended 270 mm will save energy and money.

Floor Insulation

Floor insulation works through filling the gaps between the skirting board and the floor. It can reduce the heat loss by 10%-15%.
Cost (depends on house type): £950 – £2,200 (Solid Floor)* £300 – £750 (Suspended Floor)*
Saving per year: £40 – £130 per year
Payback: Around 3-6 years

* Costs can be significantly reduced by doing the work yourself. Gaps and draughts around skirting boards and floors are simple to fix yourself with a tube of sealant bought from any DIY store. Typical costs range from around £80 to £100 if you choose to insulate them yourselves

Older homes are more likely to have suspended timber floors. Timber floors can be insulated by lifting the floorboards and laying mineral wool insulation supported by netting between the joists. Many homes – especially newer ones – will have a ground floor made of solid concrete. This can be insulated when it needs to be replaced, or can have rigid insulation laid on top.You don’t need to insulate the floors of upstairs rooms in your house if they’re above heated spaces (like the living room). But you should think about insulating any floors that are above unheated spaces such as garages, as you could be losing a lot of heat through those

Is your floor suitable?


If you have carpets you have a  99% chance of getting your insulation installed as we can access from the top of the floor rather than having to get underneath the floor .typical void measurement needed is around 200 mm this will allow for a 150mm air flow to continue. All are fitters have carpet pullers to re fit  carpet .

Laminate flooring can depend on void measurement ( gap between the floor ) in most cases we can access through under stairs cupboard or if the flooring is on beading we can take some floor up in chimney alcoves and make access point to install insulation under the floor and then relay laminate . 

Alternative options. if floors cannot be lifted we would cut a small 500mm x 500mm square under neath a couch or somewhere it will not be seen and access suspended areas to install insulation.

Note standard crawl spaces of around 400 mm (16inches) and over have a 90% chance of the job being installed . This is the gap between the top of the floor board and the bottom of the floor .


If you have a basement we will take your ceiling down and install insulation and re  board with a fire proof plaster board . Note if your basement is a heated room you will not qualify for insulation. 


Air flow 

Insulation will only be installed if there is a 150 mm gap from your joist to the floor to allow for ventilation . All  insulation will be fitted to building regulations part l .
