Standard or raised boarding
Standard boarding lays chipboard directly on the joists. It is the cheapest option. MyJobQuote says raised boarding, which uses legs to lift the boards above the joists, is needed over insulation. That is because boards laid straight on the joists would crush or replace the insulation you need underneath.
Hatch and ladder costs
MyJobQuote (13 October 2026) gives £150 to £400 for a new loft hatch and £150 to £350 for a loft ladder fitted to an existing hatch. Book a Builder (19 February 2025) gives £150 to £400 for a ladder and about £300 to widen a hatch. Ours start from £200 for a hatch and £150 for a ladder.
