Loft insulation involves installing high‑performance insulating material—typically mineral wool, sheep’s wool or PIR/PUR boards—between and/or over your roof joists to create a continuous thermal barrier. By limiting heat loss through the roof, it helps you maintain a stable indoor temperature and reduces your energy consumption.
Key Benefits of Loft Insulation
•Lower Energy Bills
Well‑insulated lofts can save households up to £370 per year on heating costs by preventing warm air escaping through the roof .
•Improved Comfort
Eliminates cold drafts and keeps rooms directly beneath the loft—such as attic bedrooms—warmer in winter and cooler in summer.
•Condensation & Mould Control
Proper insulation combined with vapour control layers reduces the risk of condensation, damp and mould in roof spaces.
•Quick, Non‑Invasive Installation
Most domestic lofts (around 50 m²) can be fully insulated in as little as one day, with minimal disruption inside the home.
•Environmental Impact
By cutting energy use, you lower your carbon emissions—helping the UK move towards its 2050 net‑zero target.
Under the UK’s Energy Company Obligation (ECO4) scheme (running until 31 March 2026), qualifying households receive full grant funding for loft insulation—including materials, installation and insurance‑backed guarantees .

1.Have an EPC Rating of D, E, F or G.
2.Live in Council Tax Band A–D in England (A–E in Scotland/Wales).
3.Receive a Means‑Tested Benefit, such as:
•Universal Credit, Income‑based Jobseeker’s Allowance, Income Support

Note: Disability‑only benefits are no longer accepted under ECO4—focus is on income‑related support.
Fill out our 2‑minute form to confirm you meet ECO4 criteria.
An MCS‑ or PAS2030‑accredited assessor visits to verify roof type, measure joist spacing and determine optimal insulation depth.
We liaise with your energy supplier to secure full funding for your loft insulation project.
Certified installers lay 270–300 mm of mineral wool or fit rigid boards, ensuring voids are filled and vapour barriers are correctly positioned.
Receive an insurance‑backed guarantee—typically up to 25 years—on both materials and workmanship.

Building Regulations recommend a minimum of 270 mm in new installs; eco‑specialists often fit 300 mm for maximum performance.
No. The process is internal—holes are less than 25 mm diameter and are neatly re‑pointed after installation.
A standard 50 m² loft typically takes 1 day to insulate, weather and access permitting.
No—if you meet ECO4 criteria, all costs are covered. There are no call‑out or admin fees.
Absolutely. ECO4 encourages a whole‑house approach: you may also qualify for cavity/solid wall insulation, boiler upgrades or heating controls under the same scheme.
