What Is Loft Insulation?

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.

Frequently Asked Questions

How thick should my loft insulation be?

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.
