Do I need planning permission for my loft conversion?

Planning permission, if required, architectural plans and building regulations are all made easy with Cool Loft Conversions – we will handle the entire process for you.

A loft conversion for your house is considered to be permitted development, not requiring an application for planning permission, subject to the some limits and conditions.

Check with your local planning office or let us organise this for you if your unsure. To summarise:

  • Permitted Development – Since October 2008, planning laws were relaxed and all houses have now got separate permitted development rights for the roof space. This new rule does not apply for flats, some new houses, properties within conservation areas and all listed buildings. Under permitted development you can make alterations such as loft conversions or small extensions or to your home without obtaining planning permission. The rules were updated to reduce red tape and encourage home owners to develop their homes.

  • Building regulations – To guarantee a safe and efficient end result, building regulations approval is required to convert any loft or attic into a liveable space and your home will be inspected by the Building Control Surveyor from your local council. Building regulations are used to ensure that any building or alteration work meets the set standards for the design and construction of buildings, mainly to ensure the health and safety for those living in or around the building. They cover areas such as energy efficiency, lighting, insulation and fire safety. Read more

  • Planning permission – If you are making changes to the external appearance of your house, then you may also need to obtain planning permission. In the UK you will need planning permission  if you want to build on land, or if you want to change the use of land or buildings. The Local Planning Authority (LPA) is responsible for granting planning permission. The LPA is normally your local Borough or District Council who will normally have a website with all of the relevant information and forms.

  • Have you got a party wall agreement with your neighbours? 
    You may be affected by The Party Wall Act 1996 if you live in a terraced or semi-detached property. This ensures your planned changes don’t compromise the strength or soundproofing of the dividing wall. All loft and roof conversions require plans and building regulation approval. From site survey, architectural and structural design, all planning and building regulation applications; everything from planning to completion is all included in your quotation – and we’ll help you through any red tape!

Planning permission is not normally required. However, permission is required where you extend or alter the roof space and it exceeds specified limits and conditions.
