Insulating your flat roof can reduce your roof’s heat loss by around 90% and save you hundreds of pounds a year on your heating bill.
How it works
Roof insulation works by helping your home to retain heat– reducing the amount of fuel you need to burn for heating and reducing your heating bills in the process.
Flat roofs should ideally be insulated from above using insulation boards. These can be attached either on top on your roof’s waterproof covering or between the timber and the weatherproof layer. It’s ideal to do if you are replacing your roof covering, and is actually a legal requirement in this situation. You can get the insulation installed on the underside of your roof instead, but this may cause condensation issues. Both types of insulation should usually be installed by a contractor.

Roof insulation can typically save the average home £180 a year on their heating bills.
- I'd like to make my period home more energy efficient, but will internal wall insulation ruin my original features, and will I lose floor area?
- Internal wall insulation is a fantastic solution for period properties or listed buildings that would require planning permission for any changes made to the outside, or where the owner wants to maintain the authentic exterior appearance of the property. You don't need to worry about losing your original features or significant amounts of floor space, though. Modern internal wall insulation systems are extremely slim, yet ultra-efficient, and lead to minimal loss of usable floor area. Installing internal wall insulation does mean that fittings such as plug sockets and skirting boards need to be repositioned, so you'll need to make sure that any decorative features like cornicing or picture rails are carefully removed and refitted following the installation. Insulating the walls could reduce the annual carbon dioxide emissions associated with your home by around 2 tonnes and save £400 per year on your energy bills.
- Is it true that everyone in the UK is entitled to subsidised insulation?
- Yes, everyone is entitled to a subsidy and some people can even have free installation. Why? Because the UK Government is obligated to reduce greenhouse gas emissions by international environmental agreements. One of the easiest ways to achieve a large reduction in greenhouse gas emissions is through increased home energy efficiency. The Government has stated that cavity wall insulation and loft insulation are the most effective methods which is why they have legislated for power/energy utilities and power companies to provide subsidies.
- I live in a rented property, can I still get my walls and loft insulated?
- Yes, people living in rented property can get their homes insulated, whether you fund it yourself, your landlord funds it or you get it funded through the Green Deal, but you must get the permission of the owner or landlord. There could also be a tax benefit to your landlord if he covers the cost - look at our LESA (Landlord’s Energy Saving Allowance) page to find out more detail.
- What is loft insulation made of?
- Typically, loft insulation is a mineral wool made out of glass or rock fibers. You can also get natural loft insulation made of sheep's wool, hemp or cellulose which will remove the need for protective equipment,
