What Survey Do I Need for Planning Permission?

Most planning applications in the UK require accurate survey information to show how your proposals relate to the existing site. Submitting drawings based on outdated OS maps or rough measurements is a common cause of delays and refusals. This guide explains which surveys planners expect to see, and when you need a professional land surveyor involved.

What to Look For

• You are submitting a planning application for a new-build, extension or change of use
• Your architect has requested an up-to-date topographical survey before designing
• The site includes level changes, retaining walls or complex boundaries
• Trees, neighbouring buildings or utilities could constrain the design
• The planning authority has asked for accurate existing drawings or sections
• You need to coordinate drainage, access and visibility splays on one plan

How We Diagnose the Problem

For most projects you will need a topographical survey of the site, and measured building surveys of any existing structures that will be altered or tied into. Boundary surveys may also be required where proposed works are close to the property line. The appropriate mix depends on project scale, local authority requirements and design ambition.

How We Fix It

Our survey partners provide planning-ready survey packs with CAD drawings, PDF plots and, where required, 3D models. We coordinate with your architect so the survey captures all essential information in one visit, reducing rework and delays. If you already have planning in place but only rough base drawings, a survey can still de-risk the build phase.
