Planning application drawings in Hillingdon

Hillingdon Council validates a householder application against a set list: a location plan at 1:1250 with a red-line boundary, a block plan at 1:500, and existing and proposed floor plans and elevations at 1:100 or 1:50, each with a scale bar and north point. Larger schemes and most conservation-area work also need a design and access statement. If any of these is missing or unscaled the application is returned invalid before it is assessed.

Almost always because the drawing pack is incomplete or wrongly scaled — a missing block plan, an elevation with no scale, no red line on the location plan, no north point. Hillingdon Council checks the pack against its validation list before an officer ever assesses the scheme, so these purely technical gaps cost weeks. Drawing to the checklist from the outset is the simplest way to avoid a return.

Yes. We prepare the full drawing set, lodge it on the Planning Portal on your behalf, pay the Hillingdon Council fee where you prefer us to, and then manage validation and case-officer questions through to the decision. You get the reference number and updates without dealing with the portal or the council yourself.

A householder application is a statutory eight weeks from validation, and a full application eight to thirteen weeks depending on scale. The date that matters is validation, not submission — an invalid pack never starts the clock. Because we draw to Hillingdon Council's checklist the application validates quickly, so the statutory period begins without the delay a returned pack causes.

You do not strictly need a planning application, but scaled existing and proposed drawings are still worth having: a lawful development certificate from Hillingdon Council proves the scheme is permitted development, which lenders and buyers increasingly ask for, and your builder needs the drawings to price and build. In a conservation area such as Old Uxbridge and Harefield Village, permitted-development rights are often removed, so a full application may be needed after all — we confirm which before you commit.

We price each Hillingdon job individually — the scope of the survey and the size of the drawing set vary from a simple rear extension to a whole-house scheme — and send a fixed, no-obligation quote within one working day. It covers the full validation pack with free revisions until Hillingdon Council decides. The Hillingdon Council application fee is separate and paid to the council. Call 020 7864 7245 to start.
