Why GBIS fit
The property sat in Council Tax band B and the EPC was E 47 — both GBIS qualifying criteria. A loft top-up from 100mm (or in places, bare) to 300mm alone would lift the EPC into the D band, which the scheme pays for without requiring a multi-measure package.
We filed the scheme application within 24 hours of the survey. Scheme approval took 6 working days.
What we installed
27 rolls of 150mm mineral-wool loft insulation, laid perpendicular to the existing 100mm to bring total depth to 300mm. Loft hatch was upgraded with a draught-seal as part of the job. Access to the loft from the interior landing meant no external scaffolding or disruption.
Install team of two arrived at 9am, finished at 12:45pm. Mrs. Hutton made us tea and we hoovered the landing before leaving.
The outcome
Immediate effect: the landing temperature rose 4°C within 48 hours. EPC re-rate two weeks later confirmed E 47 → D 68. Projected annual heating saving: £340, which on her fixed income is a noticeable change.
Paperwork to homeowner: zero. OMEGA handled the GBIS scheme application end-to-end.
“They came in at nine, left by lunch, and the landing was warmer by teatime. The paperwork side was a complete non-issue — OMEGA sorted the grants themselves.”
