Loft insulation

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.

Energy Performance of Houses

The below information illustrates the energy performance of properties in Uk. Energy ratings range from A to G, with A being the most energy efficient and G being the least efficient. The Energy Performance Certificate (EPC) rating factors heavily when attempting to sell your home, as possible buyers will see just how much they're most likely to be paying for their heating bills. House upgrades including insulation help to considerably boost a home's EPC rating.
