Lawful Development Certificate (LDC)
A Lawful Development Certificate is a legal document stating the lawfulness of past, present or future development. You might need a Lawful Development Certificate if you are using a property for a prolonged period of time without planning permission or need to establish that the current use of the building is indeed lawful or if the proposed use of the building is lawful.
There are two types of Lawful Development Certificate – Certificates of Lawful Existing Use or Development (CLUED or CLEUD) and Certificates of Lawful Proposed Use or Development (CLOPUD)
What is a Lawful Development Certificate?
A Lawful Development Certificate is a legal document issued by the local planning authority (LPA) that is generally used to regularise unauthorised development and prevent enforcement action being taken against any breach of planning policy or conditions. Importantly this is not retrospective planning permission.
The certificate establishes that an existing use, operation or activity named in it is lawful and as such cannot be enforced upon. This might be valuable in the event of selling the property, taking a mortgage on it. A common use might be to obtain a lawful development certificate after erecting an extension built under permitted development to prove that it is legal. Another common case is where a planning condition was never dealt with and so after 4 years action could no longer be taken by the local authority.
It can also be used to establish if a current use of the building is legal. For example to establish if the current use of the building is legal as offices.
The final purpose is whether the proposed use or expansion of the building in the future will be legal and not require any further planning permission. So for example in a conservation area you might apply for a LDC before erecting an extension to ensure that the proposed scheme still falls under permitted development. Refusal does not mean that it is not possible, it just means that planning permission is required. You can also appeal against refusal to issue a LDC.
Timescales – 4 or 10 years?
There are minimum time periods for eligibility depending on the type of development. Generally the period is 10 years for commercial and changes of use except in the case of a single dwelling house and then it is 4 years. The breach of planning must be continuous and current. You must prove the the time limits have been exceeded. This might be rental agreements, council tax, invoices from the works, dated photographs, leases, electoral roll, utility bills, accounts and more….. The more evidence you have the better.
- 4 years for building, engineering, mining or other operations in, on, over or under land, without planning permission. This development becomes immune from enforcement action four years after the operations are substantially completed. This includes the erection of a new building.
- 4 years for a material change of use of a building, or part of a building, to use as a single dwelling-house
- 10 years for all other development, such as a change of use or breach of a planning condition. This includes HMO C4
Examples of 4 or 10 years
This is often confused and therefore it might be best to give a few examples:
- Use of an outbuilding as a separate single dwelling (not as an annexe to the main dwelling) – 4 years
- Construction of a single dwelling (C3) – 4 years
- Use of a building as an HMO (C4) – 10 years
- Commercial use of a barn – 10 years
- Conversion of a building to a single holiday let – 4 years
- Conversion of a commercial building to a single dwelling (C3) – 4 years
Any current use of the building must be visible and in the open. There was a well publicised case of a farmer, Mr. Fidler (no I didn’t make the name up!) who built a large house behind an even larger stack of hay and then failed when he tried to use a lawful development certificate. It is important that you keep your property in open view at all times in order to qualify for a LDC.
Listed Buildings / Conservation Areas
Note that a lawful development certificate cannot be used in situations where breaches of listed building or conservation area controls may be alleged.
