Do I need an architect for planning permission?

Who can prepare and submit a planning application — and whether it has to be an architect.

The short answer

No — you do not need an architect to apply for planning permission. Anyone can submit a planning application through the Planning Portal, including the homeowner. What planning officers actually require are accurate, scaled drawings — typically existing and proposed plans and elevations, a location plan and a site/block plan — plus the application forms and fee. Those drawings can be produced by an architect, architectural technologist, architectural designer, or planning consultant; "architect" is a protected title but the work isn't reserved to architects. Professional help is most worth it where the proposal is contentious, in a conservation area, near neighbours' boundaries, or likely to attract objections — a well-presented application with the right supporting documents has a better chance of approval than rough sketches.

You can technically apply for planning permission yourself, but the quality and accuracy of the drawings matter to the outcome. Here's what a planning application needs, who can prepare it, and when it's worth paying for help.

Planning application basics

What a planning application actually needs

A householder planning application isn't about who you are — it's about whether the documents are complete and accurate. For most house projects the local authority will expect:

You can prepare and submit all of this yourself through the Planning Portal — there's no requirement for an architect, a technologist, or any registered professional to be involved. The catch is that inaccurate or unclear drawings get applications refused or delayed, and a refusal can set you back months.

Permitted development first: before applying, check whether your project even needs planning permission. Many extensions, loft conversions and outbuildings fall under permitted development. If they do, you can often skip a full planning application — though a Lawful Development Certificate is a smart way to prove it for the future.

Who can prepare your application

Several professionals prepare planning drawings, at different price points and with different strengths. For a planning application specifically, the key skill is producing clear, accurate, compliant drawings and presenting the case well — not architectural design flair as such.

When professional help is worth it

For a straightforward, uncontroversial proposal, you can prepare and submit the application yourself or use a low-cost designer to draw it up. Professional help becomes genuinely worthwhile when approval is not a given:

The bottom line: you can get planning permission without ever using an architect, and many homeowners do. But the accuracy of the drawings and the strength of the case affect the outcome, so on anything sensitive or contested it's worth paying someone who prepares these applications regularly. Remember too that planning permission is separate from Building Regulations approval — you'll usually need both, and they're assessed differently.

Frequently asked questions

Can I submit a planning application myself?

Yes. Anyone can submit a householder planning application through the Planning Portal, including the homeowner. You don't need an architect or any registered professional — but you do need accurate, scaled drawings and the correct forms and fee.

What drawings do I need for planning permission?

Typically a location plan, a site or block plan, and existing and proposed plans and elevations, all drawn to scale. Some applications also need a design and access statement. These can be prepared by an architect, technologist, designer or planning consultant.

Is planning permission the same as Building Regulations approval?

No — they're separate. Planning permission is about whether you can build something and what it looks like; Building Regulations are about how it's built safely and to standard. Most extensions and conversions need both, assessed by different teams.
