Disclaimer

FeasibilityLab is an independent planning triage tool. It is not a planning consultancy and does not provide professional planning advice.

Results generated by the free tool and guidance documents generated after payment are based on the General Permitted Development Order 2015, the National Planning Policy Framework, the London Plan 2021, and borough-specific Local Plans as at the date of generation. They are not a formal determination by any local planning authority.

Planning is a matter of professional judgement exercised by qualified officers at local planning authorities. The outcome of any planning application or Prior Approval process cannot be guaranteed. FeasibilityLab results and guidance documents give you an informed starting point, not a guarantee of any particular outcome.

Where a result or guidance document identifies that a project falls outside permitted development and requires a planning application, this reflects the rules as understood at the date of generation. Legislation changes. Local plans are reviewed. Article 4 directions are added and removed. You should verify the current position before committing to any works.

FeasibilityLab accepts no liability for loss or damage arising from reliance on a result or guidance document where: the Project Information entered was inaccurate or incomplete; the legislation or policy applicable to the project has changed since the date of generation; or the result falls outside the scope of the tool as described.

For complex or borderline cases, you should seek professional advice from a qualified planning consultant, solicitor, or heritage specialist before proceeding. FeasibilityLab will tell you when this applies.
