Question 1

What is the difference between Grade I and Grade II?

Accepted Answer

Grade I buildings are of exceptional interest and very rare. Grade II* are also highly important. Grade II is the most common type for historic homes, but all require legal consent for changes.

Question 2

How much does a planning consultant cost?

Accepted Answer

Costs depend on how big your project is. As a guide, a site visit might be £500 to £1,500. Managing a full new house application could be £2,000 to £5,000. Ask your professional for a fixed quote.

Question 3

Are building control inspections legally required?

Accepted Answer

Yes, for most structural work or extensions, the law requires these checks. Without them, you will not get a completion certificate. This makes it very hard to sell your home or get insurance in the future.

Question 4

How long does a planning appeal take?

Accepted Answer

It usually takes between 18 and 30 weeks for simple householder cases. Complex projects that need a formal hearing can take a year or more. You can track the progress of your case online.

Question 5

How long does a planning decision usually take?

Accepted Answer

Most councils aim to decide within eight weeks for standard homes. Larger projects can take up to thirteen weeks. A professional helps you avoid delays by submitting perfect paperwork first time.

Question 6

How much does a certificate typically cost?

Accepted Answer

Fees are set by your local council and are usually higher than standard ones. As a guide, expect to pay around £500 to £1,500 for the application. You will also need to pay for any building work needed to show the inspector the structure.

Question 7

Is a Lawful Development Certificate a legal requirement?

Accepted Answer

It is not compulsory to have one, but it is the only way to get a formal legal decision. Most solicitors will demand to see it when you sell the property. Without it, the council could potentially ask you to remove the work.
