How Long Does a Planning Application Take?

Before submission

A measured survey and a set of existing and proposed drawings usually take two to four weeks depending on the designer's workload and how quickly you settle the layout. Additional documents such as a design and access statement, heritage statement, or drainage details add to that.

A pre application enquiry, where one is worth doing, adds several weeks but frequently saves more than it costs on sensitive sites.

Validation

The council checks the submission is complete before the clock starts. A missing document, an unlabelled drawing, an incorrect fee or a site plan at the wrong scale all stop validation, and the application simply sits there until it is corrected.

Validation delays of one to three weeks are common and are almost entirely avoidable with a properly assembled submission.

The determination period

Once validated, a householder application carries an eight week statutory period. Within it, neighbours and consultees are notified, there is a consultation period of around three weeks for comments, the case officer usually visits the site, and a report and decision follow.

Most householder applications are decided by officers under delegated powers. Where an application goes to committee, usually because of the level of objection or a councillor request, it waits for the next meeting and the timeline extends.

What causes overrun

Councils frequently ask for an extension of time rather than refusing an application they have not finished assessing. Agreeing is normally the right move, because the alternative is often a refusal on incomplete information.

Volume of objections requiring assessment · Consultee responses from highways, drainage or conservation · Amendments requested by the case officer mid application · Committee scheduling where the decision is not delegated · Holiday periods and staffing pressure at the authority

After a decision

An approval usually carries conditions, and some are pre commencement conditions that must be discharged before work starts, typically covering materials, drainage details or landscaping. Discharging them is a separate application with its own processing time, commonly several weeks.

Build that into the programme. An approval is not the same as being able to start on Monday.

Planning the build around it

Use the determination period productively: finalise the structural design, obtain quotes, serve party wall notices and get long lead items specified. Do not order made to measure windows against an undecided application.

As a working assumption from first appointment to being able to start on site, allow three to four months for a straightforward householder application, and longer where a protected property or a contentious site is involved.

Frequently asked questions

Is eight weeks guaranteed?

It is the statutory target from validation, not a guarantee. Councils regularly request an agreed extension of time, and refusing that request rarely helps the outcome.

How long is the neighbour consultation?

Usually around three weeks from notification, during which comments can be submitted. Late comments are generally still considered if the decision has not been issued.

Can I speed it up?

Not the statutory period, but you can remove the avoidable delays: a complete validated submission, a pre application discussion on anything sensitive, and prompt responses to the case officer.

How long is permission valid?

Householder permissions are normally valid for three years from the decision, within which the development must be started.
