Insulation upgrades

Loft insulation that keeps heat in and costs down.

One of the simplest ways to improve comfort and reduce wasted heat. We help you choose the right depth, fit it neatly, and advise on funding routes if they apply.

How does loft insulation work?

Heat rises. If the loft is under-insulated, warmth escapes through the roof and your heating has to work harder. A correctly installed layer of insulation helps keep temperatures stable, reduces drafts, and improves comfort.

  • Better temperature consistency across rooms
  • Lower heat loss through the roof
  • Often a quick upgrade with minimal disruption

Benefits of loft insulation

Done properly, loft insulation improves comfort quickly. It can also support healthier homes by reducing cold spots and drafts.

  • Reduced heat loss through the roof
  • Lower running costs by improving efficiency
  • Improved comfort with fewer cold spots
  • Helps protect pipes and tanks in the loft when paired with pipe insulation
  • Supports a lower carbon footprint by reducing wasted energy
Did you know?

Many homes lose a significant amount of heat through the roof if the loft is under-insulated.

Loft insulation fitting

We fit the insulation, then check the details that help it perform properly.

Mineral fibre loft insulation
Mineral fibre insulation

A common and effective approach. We advise on depth and make sure coverage is consistent without blocking airflow where it matters.

Pipe insulation in a loft
Tanks and pipe insulation

We can check exposed pipework and advise on extra protection so heat is not wasted and frost risk is reduced.

Loft ventilation and airflow
Ventilation and airflow

Insulation works best when moisture can still escape correctly. We help you avoid trapped condensation in the loft.

You might qualify for funded upgrades

Depending on your circumstances and property, there may be support available for insulation improvements. Use the eligibility hub to get a clear answer in one place.

Loft insulation FAQs

Straight answers to the common questions.

How do I know if my loft needs more insulation?
If the insulation looks thin, patchy, or uneven, or you can see joists clearly across the loft, it may benefit from a top-up. We can advise based on what is already there.
Will loft insulation cause damp?
Insulation itself does not cause damp, but it can highlight ventilation issues if moisture has nowhere to go. That is why we consider airflow and loft ventilation as part of the advice.
Do you also insulate pipes and tanks?
We can advise on pipe and tank insulation in the loft, especially where heat loss or frost risk is a concern.
Is funding available for loft insulation?
In some cases, yes, depending on eligibility and the scheme route. Use the eligibility hub and we will confirm the best next step for your property.
