How long it takes to install insulation will depend on the size of your property. In general, loft and cavity wall insulation can be installed in a day or two. External wall insulation will usually take longer to install. The rep or installer will be able to advise you when quoting for the job how long this will be.

Loft insulation
The natural direction for heat is up and uninsulated lofts will lose a quarter of your home’s heat. This means you’ll be paying out much more than you need to on energy bills and creating more carbon emissions in the process.
With the recommended amount of loft insulation you can slash your bills for 40 years, for little installation costs and a quick payback.
Whether your home is uninsulated, or is in need of a top-up, read more to find out the savings you’ll make with our loft lagging guide.
How much will I save with loft insulation?
Loft insulation is a great way to save money as it’s installed with minimal hassle and payback is as little as two years.
The Energy Saving Trust recommends loft insulation of 270mm in thickness to make the most from its heat saving abilities.
And with this recommended level you’ll be saving up to £175 every year. Considering installation costs range between £100 and £350, payback is achievable in just two years.
With loft insulation retaining heat and reducing bills for 40 years, you’ll see a brilliant return of investment on your purchase.
As well as the financial saving you’ll make, you’ll also be benefitting the environment by reducing your home’s carbon footprint. With the recommended 270mm of lagging you’ll be able to cut emissions by around 720kg a year.
Just topping up your existing loft lagging will help you save more money too, so it’s not just uninsulated properties that will benefit.
Recommended areas to insulate
Insulating your loft will retain heat in the home but will make the area above colder, which could result in pipes and water tanks freezing. This means they need to be insulated.
With cool air in the loft you could find draughts creeping through the loft hatch. This too will need adequate insulation and draught excluding material can be fitted around the frame’s edge.
Loft insulation quotes
Cheap loft insulation is a great way to reduce your bills as most heat loss in your home is through the roof. Lagging helps to retain heat, cutting bills by up to £175 a year.

Loft insulation FAQs
The best type of insulation for your property will depend on the type of walls and any insulation that’s already present. It’s usually a good idea to have some form of wall insulation as well as loft insulation, as this helps to prevent heat loss in both areas.
This depends on the amount of insulation already present in your property. However, adding insulation has been proven to improve the energy efficiency of your home and decrease your heating bills, this is more obvious in older properties or where single glazing is still in situ.
