Avoid Planning Hassle.

1. Proof for Future Buyers & Solicitors
   The certificate is official evidence your extension was lawful.
   Too often, sellers are caught off guard without it — causing at least two months’ delay in the sale, or worst case, the buyer walks away. Why risk it?

2. Protection Against Future Council Disputes
   The certificate is official evidence your extension was lawful.
   Too often, If the council ever questions your build, the certificate is your defense.

3. Avoid Trouble with Neighbours
   Stops awkward disputes or suspicion from neighbours who think you needed planning permission.

4. Clear Record on the Planning Register
   Shows anyone (including future buyers) that your extension is legal.

5. Avoid Future Fees & Hassle
   Doing it now is cheaper and easier than trying to get proof later. With services fees steadily increasing, it’s likely the cheapest it will ever be to get your certificate sorted.

6. Peace of Mind During the Build
   Your builder knows exactly what’s allowed, so there’s no risk of accidentally crossing the line into planning territory.

What’s an LDC (Lawful Development Certificate)?
It’s your council’s written proof your permitted development extension is legal under planning rules. Not a planning application — just official confirmation, recorded for anyone to check.

If it’s Permitted Development, why bother?
Because “permitted” isn’t “proven.” Without an LDC, there’s no record you followed the rules — and that’s when disputes, delays, and extra costs creep in.

Here’s the main reasons why you need an LDC:

FAQ

What’s included in the £1100 package?

Your package covers:

• A site visit to take essential measurements

• OS plan purchase (£30)

• Full set of drawings for your LDC

• The planning fee itself (£350)

• Submission of your application

• Two design revisions

How long will it take?

We’ll carry out your survey within 5 working days of your order. Drawings are issued within 5 working days after the survey — so you’ll have your first issue in under two weeks.

Does the LDC expire?

No — once issued, it’s permanent proof that the work was lawful at the time.

How long does the council take to issue an LDC?

Most councils take up to 8 weeks to process and issue a Lawful Development Certificate.

What if I’ve already built? Does the fee stay the same?

No. While our service fee may remain similar, the council’s planning fee is almost doubled for a Lawful Development Certificate for existing use — so it will cost more than applying before you build.
