What is Loft Insulation?

Loft insulation stops up to 25% of your home's heat from escaping through the roof by adding a thick thermal barrier in your loft space. We install 270mm of high-performance mineral wool insulation, the current recommended depth.

Our professional installation takes just 2-3 hours with no mess in your living areas. We work entirely in your loft space, laying insulation between and over joists to create complete thermal coverage. The result is immediate warmth improvement and energy savings of £150+ per year for typical Yorkshire homes.

Why might you need loft insulation?

Many Yorkshire homes built before 2003 have inadequate loft insulation that wastes hundreds of pounds in heating costs every year. Here are the tell-tale signs your loft insulation needs upgrading:

High energy bills even though your home feels adequately heated downstairs

Cold upstairs bedrooms and draughty landings despite heating being on

Existing loft insulation is under 270mm thick (current standard depth)

Condensation, dampness, or mould forming in your loft space

No insulation visible in your loft or just a thin layer between joists

The benefits of loft insulation

Loft insulation delivers the biggest energy efficiency improvement for the lowest cost. Transform your Yorkshire home's comfort and running costs with professional installation.

  • Cavity wall insulation
    After receiving a letter from Northern Retrofit informing me of the government scheme to improve insulation and that it was a free service, I was initially sceptic but decided to look into it further and, after a very pleasant phone conversation, I was assured it was ‘legit’ and went ahead with arranging cavity wall insulation which was carried out efficiently by a couple of very pleasant workers who made sure I had everything in place to keep my property sufficiently insulated also checking whether or not I needed ventilation/extractor fans which they were only too pleased to supply and fit at zero cost to me! Excellent service and I would not hesitate to recommend Northern Retrofit.

  • Room in roof insulation
    From initial contact to completion, the room-in-roof work done by Northern Retrofit on my house was completed to my total satisfaction. The workforce was efficient, friendly, and cooperative throughout the entire process. I would highly recommend this company to anyone considering similar work. One point to note is that, as with any plastering work, dust can get into the air, so it’s important to adequately cover furniture and belongings beforehand.

  • Cavity wall insulation
    Free cavity wall insulation and extractor fan in bathroom fitted quickly and professionally. Small leakage of beads in the cellar which they came back and sorted the same day I rang. No complaints whatsoever, rare to get a worthwhile service for free! Thank you

  • Cavity wall extraction
    First class service from Northern Retrofit. We had our old cavity wall insulation taken out, and replaced with new. We were happy from start to finish, and found them to be both friendly and efficient. A special thanks must be given to Lucy in the office, and Kelby and Elliott who carried out the work. We are very happy with the result, it has made the house so much warmer. Thank you.

Frequently Asked Questions

Frequently Asked Questions

Do I need to clear my loft first?

If your loft is easily accessible and mostly clear, we can work around a few items. We’ll advise ahead of time if anything needs moving.

How thick should loft insulation be?

The recommended depth is 270mm. Many older homes have far less, so a top-up is usually worthwhile.

How long does it take to install?

Most loft insulation jobs take less than half a day. Our team works quickly and leaves everything tidy.

Do you work for councils, housing associations and contractors?

Yes. We deliver loft insulation for councils, housing associations and main contractors, from single properties to larger programmes.

Will loft insulation affect ventilation?

We keep the eaves and roof space ventilated as we install, so the loft stays dry and condensation isn't trapped.

What areas do you cover?

We cover the North East, North West, Yorkshire and the Humber, the East and West Midlands, the East of England and Wales, from our head offices in Beverley and Warrington.
