About this service

We lay insulation between the ceiling joists and a second layer across them, so the whole loft floor is covered evenly. We keep the edges of the roof clear for air, lag pipes and the tank, and insulate the hatch.

What’s included

  • A look at your loft before we start
  • Insulation between the joists
  • A second layer across the joists
  • The edges of the roof kept clear for airflow
  • Pipes and tank protected from frost
  • An insulated, draught-sealed hatch

We price the job after looking at your loft. You get a written quotation before any work is agreed.

Why the loft first

Warm air rises through the house and collects under the top-floor ceilings. With little insulation above, it passes into the roof space and out. Insulating the loft floor keeps that warmth in the bedrooms and landing, where you feel it.

How we do it

The first layer fills the gaps between the joists. The second runs across them so there are no cold lines of bare timber. We leave a gap at the eaves so air can move under the roof and keep it dry, and we move cables to sit on top.

Your choice of material

Most homes get mineral wool, which is good value and works well. If you’d prefer sheep’s wool or recycled polyester, ask and we’ll include it in your quote.

The process

How it works

  1. Tell us about your home

    The kind of house, what you’d like and your postcode. It takes about a minute.

  2. We take a look

    We check the loft and explain what would make the biggest difference, in plain words.

  3. Your quote in writing

    The work, the material and the price, so you can decide in your own time.

  4. A warmer home

    If you go ahead, we agree a day that suits you and leave the house as we found it.

Loft insulation: your questions answered

How deep will it be?
For mineral wool, around 270 mm is commonly recommended. We’ll say the depth we suggest for your home in the quote.
Will I notice a difference?
Most people notice the upstairs rooms and landing feel warmer and hold their heat better.
How long does it take?
Most lofts are done in a day.
Can I still use the loft for storage?
Yes. A raised floor above the insulation gives you storage without squashing it.
Is the work guaranteed?
Eligible installations come with a guarantee of up to 5 years. Your written quote says whether your job qualifies and what it covers.
