Cambridgeshire

A flat fenland county in the East of England, home to the world-famous University of Cambridge and the scenic River Cam.

What is Planning Permission

Planning permission is a statutory approval required before most building or land-use changes can legally proceed. Granted by the local planning authority, it ensures new development aligns with national planning policy and the local plan. Failing to obtain it can result in enforcement notices and the removal of unapproved structures.

When Do You Need Planning Permission

You need planning permission whenever you intend to build a new home, make a substantial extension, or change how a building is used. Permitted development rights allow some minor works without consent, but these are restricted in conservation areas, AONBs, and on listed buildings. Always check with your local authority first.

Where Can I Get Planning Permission in Cambridgeshire

Planning permission in Cambridgeshire is granted by the relevant local planning authority. You can submit a full planning application through the Planning Portal at planningportal.co.uk, which routes your application to the correct council. Pre-application advice is also available directly from the local authority's planning department before you commit to a full submission.

Planning Permission in Cambridgeshire

Planning permission in Cambridgeshire is administered across multiple authorities: Cambridge City Council covers the city, while six district councils cover the county - South Cambridgeshire, East Cambridgeshire, Fenland, Huntingdonshire, and the newer merged authority. Each authority has its own Local Plan, validation requirements, CIL schedule and design policies.

Cambridge City Council's planning pages provide detailed guidance on the application process for the city area. Full planning applications for new dwellings in Cambridge require a design and access statement that engages with the Cambridge Design Guide, a heritage impact assessment for sites within or adjacent to conservation areas, and a transport assessment or parking statement in line with the council's parking standards. Cambridge City Council has adopted ambitious sustainability standards for new development, and self-builders should familiarise themselves with the council's sustainability checklist which is required to accompany all residential planning applications above a minimum threshold.

The Cambridge Local Plan 2018 is the primary policy framework for the city. Policy 55 (Cambridge vernacular and building materials) and Policy 57 (design of new buildings) are directly relevant to self-build proposals. The Local Plan places strong emphasis on design quality and expects proposals to contribute positively to the character of their immediate setting. Given the historic character of much of Cambridge, this requires careful contextual analysis and a design approach that responds thoughtfully to scale, massing, materials and roofscape.

South Cambridgeshire District Council's planning portal provides access to the adopted Local Plan 2018 and its associated policies. Policy HQ/1 (Design Principles) is the primary design policy for the rural area, requiring development to demonstrate a thorough understanding of local character and to use materials and building forms that are appropriate to the Cambridgeshire village vernacular. The council's Design Guide SPD provides the detailed implementation framework for this policy.

Community Infrastructure Levy in Cambridgeshire varies significantly by authority. Cambridge City Council and South Cambridgeshire District Council both operate CIL schedules, with rates reflecting the high land values of the Greater Cambridge area. Both councils offer the self-build CIL exemption for qualifying applicants. The exemption requires submission of Form 7 (self-build exemption claim) before development commences, followed by a completion declaration. The councils have a Joint CIL team that can advise on rates and the exemption process.

The Greater Cambridge Shared Planning Service, established to jointly administer planning for Cambridge City and South Cambridgeshire, is a material development in the local planning landscape. This shared service is developing a new joint Local Plan - the Greater Cambridge Local Plan - that will replace the existing separate plans for both authorities. The emerging plan is expected to set ambitious policies on sustainability, design quality and biodiversity that will have direct implications for self-builders in both areas.

Flood risk assessment requirements are particularly significant in Cambridgeshire. The Environment Agency and the multiple Internal Drainage Boards that operate across the county must be consulted on any planning application in areas at risk of flooding. Self-builders in Fenland and East Cambridgeshire should expect detailed scrutiny of drainage proposals and may be required to incorporate raised floor levels, flood-resilient construction and sustainable urban drainage systems.

Pre-application advice is strongly recommended across all Cambridgeshire authorities, given the complexity of the planning environment and the high costs associated with abortive applications where fundamental policy barriers exist.
