Are there grants for loft or cavity wall insulation in Northern Ireland?
Yes, two live routes in 2026. NISEP, the NI Sustainable Energy Programme, funds loft and cavity wall insulation now, fully funded for qualifying lower-income households with part-funded places on some schemes for everyone else. The NIHE-run Affordable Warmth Scheme covers insulation in the least energy-efficient homes, worth up to £7,500. Loft insulation is called roofspace insulation in much NI scheme paperwork, same measure, same money.
The short version: NISEP funds loft and cavity wall insulation through approved scheme managers right now, with fully funded places for lower-income and vulnerable households and part-funded places on some schemes for everyone else. The Affordable Warmth Scheme, run by the NI Housing Executive, covers insulation in the least energy-efficient homes, worth up to £7,500, and runs until March 2028 while its £150m successor arrives. One naming note: GB sites say loft insulation, NI scheme paperwork says roofspace, plenty of people say the attic. Same measure, same money.
Who qualifies, current income thresholds, why disability benefits have not counted as income under the Affordable Warmth test, how to apply without losing the grant, and the doorstep scams to avoid: all of that lives in our full insulation grants guide below, with a printable version if you prefer paper.
