Loft insulation

The cheapest measure on almost every plan, and usually the first we recommend. Topping a loft up to 270mm adds real EPC points and noticeably lowers your tenant's heating bills.

What it is

Mineral-wool or equivalent insulation laid between and over the ceiling joists in an accessible loft, brought up to the current recommended depth of around 270mm. If your loft has some old, thin insulation we top it up rather than start again. Where the loft is boarded for storage we raise the boarding on battens so the insulation is not crushed, keeping its performance.

Why it earns its place first

Around a quarter of the heat in an uninsulated home escapes through the roof, so loft insulation is one of the highest points-per-pound measures for reaching EPC C. It is quick to fit, needs no disruption to the tenant beyond loft access, and it is the classic "fabric-first" step the 2030 standard requires before you spend on heating or generation. For most Greater Manchester terraces and semis it is a same-day job.

Which homes suit it

Any property with an accessible pitched loft and less than about 200mm of existing insulation. Homes with a converted loft or room-in-roof need a different approach — see room-in-roof insulation. Damp or condensation issues are dealt with first, and we make sure ventilation and any downlights are handled correctly so you never trade a warmer loft for a moisture problem.

Grants that apply

Loft insulation is covered by the Warm Homes: Local Grant for eligible Greater Manchester tenants, and by ECO4 while it runs (to 31 December 2026). Where it is grant-funded your contribution can be nil on a first property. It is also zero-rated for VAT until 31 March 2027. We check every route on the grants page before you spend.

How we do it

Surveyed and coordinated to PAS 2035, installed by our accredited partner LAMTANS Engineering to PAS 2030 standards, and lodged with TrustMark so it counts on your evidence file and towards the £10,000 cost cap. You get a fixed price from our own book — no contractor mark-up — and it forms part of the plan your free assessment produces.

Not sure how much your loft needs? The free 2030 Compliance Assessment measures it and prices it as part of your whole-property plan.
