  • "Save up to £350 on your energy bills, every year! **"

  • "Recently had Solar fitted, and from day one up until install I am pleased with my experience with Effective Home, I've never experienced a virtual survey before and at first I was curious about it, but it was straight forward with no hassle and want to praise the company for doing a great job! "

  • ""I was worried that I was dealing with an "office" hundreds of miles away from me. As it transpired this was not a problem. The negotiations were formal yet friendly. The idea of having a link person who you can contact easily was a great idea. It didn't always work, particularly when I was trying to get dates settled. Once agreed, the scaffolding and solar panel completion went very well, with great guys doing the work.""

  • "From start to finish brilliant. From assessor to fitter. We are very happy with the work - excellent service. They said they were going to do it in a day, and they did. They did not get in the way once."

  • "Above and beyond! The work was done to a high standard. No extra cost, right on the quoted amount. I'm always sceptical about these sort of things, but I'm extremely happy."

  • "They replaced an external oil fired boiler for us - it was the first time we had used them but we would be willing to use them again as they definitely lived up to our expectations."

Types of loft insulation

For uninsulated

Rolls of Knauf mineral wool or earthwool insulation – 270mm thick.

The first layer is laid between the joists – the horizontal beams that make up the floor of the loft – then another layer is laid at right angles to cover the joists and make the insulation up to the required depth.

Top up an
insulated loft

Thinner rolls of Knauf mineral wool or earthwool insulation – 120mm to 270mm.

If your current loft insulation isn’t to the recommended depth, we can top it up to 270mm with an extra 150mm layer of mineral wool. This could save you a further £25 a year on heating bills – ask us for a price.

Pipes, water tank and loft hatch

Insulating between the joists of your loft will keep your house warmer, but not the roof space above.

To prevent cooler air in your insulated loft meaning cold draughts come through the loft hatch, we fit an insulated loft hatch and put strips of draught-excluding material around the hatch edges.

Can all lofts be insulated?

If your loft is easy to access and has no damp or condensation problems, we should be able to insulate it.

What will you do on installation day?

If access is easy and your loft joists are regular, we will install rolls of mineral wool insulation. The first layer is laid between the joists – the horizontal beams that make up the floor of the loft – then another layer is laid at right angles to cover the joists and make the insulation up to the required depth.

Any tanks and pipes that are in the loft would be insulated as part of the install to prevent them from potentially freezing in the future. Also, as part of the installation process, we need to ensure your loft is adequately ventilated. In some cases we might need to add some roof or tile vents and in others where the loft space is already adequately ventilated we would not need to make any adjustments.
