Why loft quotes vary — and our fixed price policy:
Loft boarding and conversion prices can vary hugely between companies — usually because of differences in loft size, hatch access, existing insulation depth, and whether a raised or standard boarding system is genuinely needed. We explain which of these apply to your loft during the free survey, then agree a fixed price before any work begins. No call-out charge. No surprise extras.

Frequently Asked Questions
All Your Most Common Questions Answered
Cost depends on your loft's current insulation depth, access, and whether it's rolls, boards, or professionally blown insulation. We confirm an exact price after a free survey — there's no charge for the visit and no obligation to proceed.
Loft Insulation is laid flat between and over the joists, on the loft floor — the "cold roof" method, used when the loft stays an unused storage space. Warm Roof Insulation is fitted along the rafters, on the roof slope — the "warm roof" method, required whenever the loft becomes a habitable room, such as with a Velux conversion. They solve different problems and aren't interchangeable.
Often not — many Velux (rooflight) conversions fall under Permitted Development rather than requiring full planning permission. However, this has genuine limits: volume allowances for extensions, conservation area restrictions, and flats or maisonettes are generally excluded from Permitted Development rights. We'll confirm your specific situation during the survey rather than assume.
Not directly, with standard boarding — laying boards straight onto mineral wool insulation compresses it and reduces how well it performs. A raised boarding system lifts the boards above the insulation on a supporting frame, preserving full insulation depth while still giving you usable storage space.

Yes. All loft insulation, boarding, and conversion work comes with a 12-month workmanship guarantee. If anything we've carried out develops a fault within 12 months, we return and repair it at no charge.
