About this service

Loft insulation is laid between and over the ceiling joists to slow heat escaping through the roof. In most pitched-roof homes it is one of the simplest insulation jobs to arrange.

What’s included

  • A check of your loft, access and existing insulation
  • Advice on the right depth and material for your home
  • Insulation laid between and across the joists
  • Eaves kept clear so the roof space can ventilate
  • Loft hatch insulated and draught-proofed where needed
  • A written quotation before anything is agreed

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

Why insulate the loft?

Warm air rises, and in a house with little or no loft insulation a good share of the heat you pay for escapes through the ceiling and out through the roof. Insulating the loft slows that loss, which helps the rooms below stay warmer and the heating work less hard.

How much insulation does a loft need?

For mineral wool, 270mm is the depth commonly recommended for a loft in the UK. Many older homes have far less: a thin layer laid decades ago that has since compressed. Other materials, such as foil-faced products or rigid boards, reach a similar level of insulation at different thicknesses, and we will explain what suits your loft.

What we look at

  • Access – the size and position of the hatch, and whether the loft is safe to work in.
  • Existing insulation – whether it can be topped up or needs taking out first.
  • Ventilation and moisture – signs of condensation, mould or roof leaks, which should be dealt with before new insulation goes in.
  • Wiring and pipes – cables that should not be buried, and water tanks and pipes that need protecting from frost once the loft is colder.
  • Storage – if you use the loft for storage, raised boarding lets you keep the space without squashing the insulation.

How we work

We look at the loft first, in person where it needs it, and send you a written quotation that sets out the material, the depth, everything included and the price. Nothing is agreed until you have that in writing. If you go ahead, we book a date and do the work, leave the loft tidy and take the waste away.

What a well-insulated loft looks like

  1. Insulation between the joists

    The first layer fills the gaps between the ceiling joists, sitting on the ceiling of the rooms below.

  2. A second layer across them

    Laid at right angles over the joists, so the timber isn’t a cold bridge. For mineral wool, 270mm in total is the depth commonly recommended.

  3. Eaves left clear

    A gap at the edges lets air move through the roof space, which stops condensation building up.

  4. Raised boarding for storage

    Boards on supports above the insulation, so you can store things without squashing it.

  5. Insulated, draught-proofed hatch

    The hatch is a hole in the insulation unless it’s insulated and sealed too.

  6. Pipes and tanks protected

    A well-insulated loft is colder, so water pipes and any tank up there need lagging against frost.

The process

How it works

  1. Tell us about your home

    Send your postcode and a few details about the property and what you have noticed in the loft. It takes a couple of minutes and costs nothing.

  2. We get in touch

    We call or email to talk through what you need and arrange a time to look at the loft.

  3. We survey and quote

    We check the loft, in person where it needs it, and send you a written quotation that sets out the work and the price.

  4. You decide

    There is no obligation. If you go ahead, we agree a date with you and carry out the work.

Loft Insulation: your questions answered

Is loft insulation worth it?
In most homes with little or no loft insulation, adding it is one of the more straightforward ways to reduce heat loss. How much difference it makes depends on how much insulation is there now, the type of house and how you heat it. We can tell you what your loft needs.
How long does loft insulation take to install?
A typical loft is usually done in a day or less once the job is booked. Larger lofts, difficult access or removing old insulation first can take longer. We give you a time estimate with your quote.
Is loft insulation guaranteed?
Eligible installations come with a written guarantee of up to 5 years. Whether it applies to your job, how long it runs and what it covers are confirmed in your written quotation. A guarantee covers the insulation work, not existing roof leaks or other problems with the house.
Do I need to empty the loft?
Usually the loft needs to be clear so the floor area can be insulated. If you store things up there, ask us about raised boarding, which lets you keep storage space above the new insulation.
Does it cost anything to enquire?
No. Sending your details is free and there is no obligation to accept any quotation.
Who will contact me?
We will, by phone or email, to talk through what you need and arrange a time to look at the loft.
