Every service we price, what each fee includes, and a link to the service page. Every price is the full fee and includes VAT. Council planning application fees are separate and paid to the council. Where a price starts with “from”, it is the fee for the simplest standard case; larger or more complex projects are confirmed as a single fixed fee in writing after a free assessment.

How these prices were set. Prices checked against published London competitor fees on 14 October 2026. We re-check them regularly and update this page when they change.
Council fees are separate. The statutory planning application fee is set nationally, paid to your council and is not part of any price above. See our planning permission cost guide for the current England fees and their source, and read how the five cost drivers work in our planning drawings cost guide.
Tell us about your project and we confirm a fixed, no-obligation fee within one working day, with revisions free until your council decides.
