Your Loft Conversion Project

UK Planning laws were relaxed in October 2008. In most cases any loft conversion will be regarded part of your property's 'Permitted Development Right'. As a result, nearly all loft conversions will only require Building Regulations Approval.

Getting Planning Permission

For further information relating to your 'Permitted Development Rights' visit the interactive house planning portal for loft conversions. If planning permission is a requirement it can take up to 6-8 weeks to get approval. If you are uncertain whether your property has 'Permitted Development Rights; intact or in place, we would recommend that you check with your local council who will be able to advise you. Please note that if your property is in a Trust Area you will also need to obtain Trustee consent which can take between 6 and 8 weeks.

Building Regulations

Building Regulations are specifically concerned with the structural safety of a build. They are linked to the checking and subsequent approval of plans for any construction work awaiting commencement. Building inspectors will visit the site during various stages of the construction to ensure that the build is being completed to the correct specification. Approval can take approximately 6 weeks to obtain.

The complete process, from initial survey to Building Regulation Approval shouldn't take more than 8-12 weeks. Once all approvals have been received, we will liaise with you to agree a start date for work to begin. Please note that if planning permission is required, the start date can be delayed by 6-8 weeks.

Permitted Development Rights - What does not meet the criteria?

  • If your property is in a Conservation Area or is a Listed Building you will need Planning Permission as these do not come under the ‘Permitted Development Rights’ criteria.

  • If your property’s ‘Permitted Development Rights’ have been removed as part of a previous planning application.

  • Verandas, balconies, raised platforms are not classed as ‘Permitted Development’

  • If your loft conversion extension is over 50 cubic metres for a detached and semi-detached property or 40 cubic metres for a terraced house.

  •  Some new housing developments have had their ‘Permitted Development Rights’ removed by the Local Authority when the initial Planning Permission was granted for the development.

  • If your proposal requires any extensions beyond the plane of the front of house if fronting a public highway.
