How we price Part L work
The fee follows the modelling, not the number of doors. A site of forty houses built from four types costs far less per plot than forty individual designs, because the work is in the distinct types and the site-wide checks rather than in repetition.
Everything is quoted in writing from the drawings before anything is modelled, and the quote says what happens at design stage and what happens at as-built, so the second invoice is never a surprise.
Guide bands are indicative only, and the VAT position is confirmed on the quote. If your scheme does not fit a band — a heat network, a listed conversion, a mixed-use block — send it over and we will price it properly rather than guess.
