Listed building consent granted: five assumptions about the conditions, and what the rules say

Consent is not permission to start with no further steps. Listed building consent can carry conditions, some of which ask for details to be approved before the works go ahead. Doing the work without meeting them can be a criminal offence under section 9 of the 1990 Act.

This post takes five common assumptions about a granted consent and sets each against what the law and the official guidance say. It picks up from the worked example of one application, which stopped at the point the decision notice arrives.

Does a granted consent mean you can start straight away?

• The assumption: the decision notice is the green light, so the builder can book a start date.
• What the law says: works must be authorised under section 8 of the 1990 Act, and section 7 bars works that are not. Section 18(2C) confirms that works may begin as soon as consent is granted, but section 9(2) makes it an offence to fail to comply with a condition while carrying out the works.

So the question is not whether consent exists. It is whether every condition that bites before or during the works has been met.

Are conditions only small print?

• The assumption: conditions are standard wording that can be read after the work is under way.
• What the law says: section 17(1) lets a council require particular features to be preserved, damage from the works to be made good afterwards, and in some cases a building to be rebuilt using original materials where practicable. These are real obligations on the person doing the works.

Read the conditions on the decision notice line by line, and read them to your builder as well. The person holding the tools is the one most likely to cause a breach without knowing it.

Should every detail have been settled in the application?

• The assumption: if the council granted consent, it must have approved every detail already.
• What the law says: section 17(2) allows a condition to require specified details to be approved later. The local planning authority normally gives that approval.

Typical later details are samples, joinery profiles or a repair method. Check the wording of each condition for the exact items and for the point at which the council must have approved them.

Can you discharge a condition with a quick email?

• The assumption: a friendly note to the case officer is enough.
• What the guidance says: Planning Practice Guidance on planning conditions says a request to discharge a condition on a planning permission must be made to the local planning authority in writing, with its fee paid when the request is made. It also says the authority must give notice of its decision within eight weeks, or sixteen for development needing environmental impact assessment.

That guidance is written for planning permission, and the page does not mention listed building consent. Ask your own council how it wants discharge requests for a listed building consent made, and what it charges, before you assume the planning permission rules carry across.

Is there no rush once you hold the consent?

• The assumption: the consent will wait until you are ready.
• What the law says: section 18(1) requires every consent to carry a condition that the works begin within three years of the grant, unless the council sets a different period. If a consent is granted without that condition, section 18(2) treats it as if it were there.

Details that need approval take time to prepare and to be considered. Build that time into the programme so the start date is not set by a condition you left until the end.

What if something is found once the work starts?

Opening up an old building often shows something the drawings did not. If the discovery means the approved works would change, stop and talk to the council before carrying on. Section 9(3) gives a defence for urgent works, but it applies only where all four of its tests are met, including written notice to the authority as soon as reasonably practicable.

A short list to work through before the first day on site

1. Read every condition on the decision notice, and mark which ones must be met before work starts.
2. List the details to be approved and the date each is needed.
3. Ask the council how it wants requests made, and whether a fee applies.
4. Send the details in writing and keep a copy of what the council approves.
5. Tell the builder which conditions apply, and give them the approved details.
6. Check the start date against the three-year period, or whatever period your consent states.

Where would a professional help?

A heritage professional can prepare the details a condition asks for in the form a conservation officer expects, and can say whether a change found on site is within the consent. If you want a first read of a building before any of this, HeritageAI's Preliminary Planning and Heritage Appraisal is generated automatically from the details you give and sent by email. It is a starting point, not professional advice, and the Old Posingford sample shows its shape.

The wider rules, from when consent is needed to what happens at a decision, are gathered in our listed building consent guide. If your works are internal, the earlier post on internal works explains how to tell whether consent is needed at all.

It is a good time to be looking after an old building. Skilled repairers, careful owners and clearer tools mean more people can follow the work from decision notice to the final coat of lime.
