A self-build mortgage releases funds in stages against the value of work completed, verified by a valuer or the project professional. You usually need site ownership, full planning permission and evidence of a realistic build cost before drawdown begins.
Lenders typically release funds in four to five stages — foundations, wall plate, roofed and plastered, and completion — with a valuation inspection at each. Because money arrives after work is done, you need working capital or a first tranche of your own funds.
Lenders require full planning permission with the appeal period expired, a costed schedule, proof of all-risks insurance and confirmation of the certification route being used.
