If you're applying for planning permission for an extension or alteration, the council first checks your application is complete — 'validation' — before the clock on a decision really starts. Getting the drawings and documents right first time avoids weeks of avoidable delay. Here's what a Wirral householder application typically needs.
In short
A householder planning application has to be 'valid' before the council will consider it. That usually means the right form, ownership certificate and fee, a correct location plan, and clear existing and proposed drawings. Missing or inaccurate drawings are a common cause of delay. SC Design prepares the drawings; Wirral validates and decides the application.

A householder application is the route for most home improvements that need permission — extensions, some alterations, and similar works to a single house (not flats). Wirral checks each application against national requirements and its own local validation checklist.
If important information is missing, Wirral cannot register the application as valid — so completeness matters as much as the design.
Typically you'll need the correct application form, a signed ownership certificate, the fee, a location plan, and the other plans required for your proposal.
The exact list depends on the project, which is why it's worth checking the validation checklist before submitting rather than after.
A location plan identifies the site on an up-to-date map at a recognised scale, with the application site outlined in red. If you own other nearby land, that is usually outlined in blue.
Getting the scale, extent and red/blue lines right is a small detail that often trips applications up.
Householder applications usually need existing and proposed drawings — floor plans and elevations that show the property as it is and as you intend it to be. They let the council assess size, appearance and the effect on neighbours.
Common causes of delay are an incorrect location plan, missing existing or proposed drawings, inconsistent measurements, and a description that doesn't match the drawings. We prepare clear, consistent drawings to reduce those validation hold-ups — though the council always validates and decides.
You don't need a full brief or drawings to get started — just your name and one way to contact you. The rest is optional, and you can send more whenever it suits you.
