Can I get free insulation UK 2024?

Yes, if you're on certain benefits or have a low income, you may qualify for free insulation through ECO4 (England, Scotland, Wales) or GBIS (Scotland). Qualifying benefits include Universal Credit, Pension Credit, Child Tax Credit, and others. Private landlords and councils can also apply for properties.

What is the ECO4 scheme UK?

ECO4 is a government scheme requiring large energy suppliers to fund energy efficiency improvements for qualifying households. It runs until 2026 and covers insulation (loft, cavity wall, solid wall), heating upgrades, and other measures. You must be on qualifying benefits or in low-income households.

How much does loft insulation cost UK?

Professional loft insulation costs £400-£600 for a typical semi-detached house. DIY costs £200-£350 for materials. If you qualify for ECO4 or other schemes, it can be free. Loft insulation saves £200-£300/year on heating, so payback is 1-3 years even if paying.

Is cavity wall insulation worth it UK?

Yes — cavity wall insulation typically saves £200-£400/year on heating bills. Cost is £500-£1,500 depending on house size. Payback is 2-5 years. Free through ECO4 if eligible. Most pre-1990s homes with cavity walls benefit significantly. Not suitable for all walls — get professional survey.
