Planning permission should not be this hard to understand.

The gap

Navigating planning permission is harder than it should be. National permitted development rules are detailed, while local designations and policies can change the position for a particular property. Finding the right information is one problem. Working out which route is likely to apply is another.

For most small residential projects, hiring a consultant before you know what you need costs more than the answer is worth. Working through it alone is difficult. FeasibilityLab was built to fill that gap.

What FeasibilityLab is

The free planning checker sits between the project idea and the professional process. It applies national planning rules for England to the answers you provide and explains the likely route in plain English. It does not submit applications or replace the professionals a complex project needs.

It gives you a starting point for the next conversation. Local plans, site-specific constraints and council judgement must still be checked separately.

Who we are

FeasibilityLab was built by a practitioner with over ten years of experience in the construction industry. The background spans architectural training and practice, sustainability consultancy, and accredited energy assessment (OCDEA and NDEA), with CEng CIBSE accreditation in progress.

Limits to be aware of

FeasibilityLab does not make applications, represent you, or act on your behalf. It has no affiliation with any local council or planning authority.

The tool applies national rules to the answers you give. It does not assess local plans or automatically verify conservation areas, Article 4 directions, listed status, flood zones or other site-specific constraints. If the case is complex or the stakes are high, verify the position with your local planning authority or a qualified planning consultant before you commit to anything.

Planning is ultimately a matter of professional judgement exercised by local planning officers. FeasibilityLab gives you a well-informed starting point, not a guarantee. The tool is transparent about where uncertainty exists.

Kept up to date

The free checker is maintained as national planning legislation and relevant national policy change. Results are generated from the current checker each time you use it. Because local plans and constraint records are outside its scope, confirm those separately with your local planning authority.
