Tools for London homeowners
Free, interactive tools to help you plan a London home project. They give cautious, educational guidance — not a determination — and always point you to a property-specific conversation.
Planning drawings package finder
Enter your address and the works you are considering to see the right drawings or planning package — from a £395 starter review to fixed-fee planning drawings, Licence to Alter and listed/conservation support.
Open toolWhat will a planning application cost?
Estimate the two costs people muddle — the statutory fee paid to the council and Planning Portal, and our fixed fee for the drawings — for extensions, lofts, flats and listed buildings.
Open toolWhat drawings do I need?
Choose your project type to see the drawings and stages a London home project usually involves, and the services most relevant to it.
Open toolDo I need planning permission?
Answer three questions for a cautious, plain-English sense of the planning permission or consents your project is likely to involve.
Open toolPrefer to just ask?
Send us the property address, type and a short description of the work, and we will advise on the drawings, approvals and consultant input your project will need.
