Levelling Up and Regeneration Act 2023 and abolishment of the “4 year rule”

Ed Telepneff examines a key proposal contained in the Levelling Up and Regeneration Act in relation to the time limit for enforcement against breaches of planning control.

Nearly 18 months since the bill was first published, the Levelling-up and Regeneration Bill (LURA) received Royal Assent and became law on 26 October 2023.

As is common with this type of legislation however, most of its provisions won’t come into effect until enabling secondary legislation is in place.

One, not insignificant element of the LURA that had been awaiting such secondary legislation is section 115. On 2 April 2024, the Planning Act 2008 (Commencement No. 8) and Levelling-up and Regeneration Act 2023 (Commencement No. 4 and Transitional Provisions) Regulations 2024 (2024 Regulations) were made, giving effect to Section 115 which from 25 April 2024 will amend 171B of the Town and Country Planning Act 1990 (1990 Act) by simply deleting the word four and replacing it with the word ten.

The effect of this modification will increase the time limit within which breaches of planning control in England can be enforced against for building operations and unauthorised change of use of a building to a dwelling, from 4 years to 10 years. It’s hoped this change in the rules may relieve some pressure on authorities.

The position prior to 25 April 2024

Operational development is wide in its scope and includes building, engineering, and mining, in, on, over or under land. Operational development that is not permitted development, may be subject to enforcement action if it has been carried out without consent. After 4 years from the date that operational development is substantially complete and as long as there has been no deceit or concealment, that development will be immune from enforcement action.

As is the case with operational development, if a use of a building or premises changes to be used as a single dwelling or multiple dwellings, no enforcement action can be taken after 4 years from the date the use began.

Once 4 years has expired and it is no longer possible for enforcement action to be taken, a previously unlawful development will become lawful. As an example, an extension to a property built without planning permission; or a house that was converted to flats without planning permission, will become lawful, if no enforcement action has been commenced within 4 years.

What the LURA changes

The 4-year rule for breaches of planning control will be abolished and the planning enforcement period for all breaches of planning control will rise to 10 years.

So, the extension and the converted flats will have an extra 6 years, within which enforcement action can be taken, before they become lawful. This change will no doubt be of significant concern to any landowners / developers who own land or buildings without planning permission (or certificate of lawfulness) where the development has been carried out within the last 10 years.

Transitional arrangements

The 2024 Regulation include transitional provisions which ensure that the amendments to 171B of the 1990 Act made by section 115 won’t apply to any breaches which occurred (in the case of operational development the date of the breach being the date the operations were substantially completed) before 25 April 2024.
