Econoloft constructs all types of loft conversions for homeowners in Sutton and across the UK and with over 150 years of combined experience, we know all the different planning permission requirements. While many attic conversions do not need planning permission, the specifics of your property and project may require approval. As a customer focused loft conversion company, we know that there is no one size fits all solution when it comes to loft extensions, which is why we provide tailored plans for each job, including advice and assistance with planning.

Before starting any work, our loft conversion specialists walk through your project with you and make sure you understand any planning requirements. If necessary, we then help with getting approval and resolving any planning issues.

Whether you just require loft conversion planning advice or full design and build services, Econoloft provides everything you need. Our services include:


  • Tailored advice, planning and designs

  • All trades and services for your conversion

  • Supply and fabrication of steels to precise measurements (we are able to offer this as expert steel suppliers)

  • Full snagging and compliance/safety inspections


While most loft conversions in Sutton do not require planning permission because they fall under permitted development, if your project exceeds certain limits or conditions, you will need prior approval. Furthermore, certain properties will need planning permission, such as listed buildings, flats, maisonettes and houses in conservation areas. As an experienced loft conversion company, we approach every job individually and make sure all necessary applications, permissions and plans are in place for your project.

Will I Need Planning Permission?

Whether or not you need planning permission depends on the specifics of your loft extension and our loft conversion specialists will advise on this. However, to fall within permitted development rights, your project in Sutton must meet the following criteria:


  • Once work is complete, no part of the house can be higher than the existing roof.

  • Attic conversions cannot extend beyond the plane of an existing roof slope that faces a highway.

  • The volume of the resulting roof space must not exceed the volume of the original roof space by more than 40 cubic metres for terraced houses, or 50 cubic metres for other property types.

  • Loft conversions cannot include a veranda, balcony or raised platform.

  • The house is not in a conservation area.

  • The materials used for exterior work must be similar in appearance to the existing building.


It is important to note that this is just a summary of some of the key points, and there are further conditions that apply for your conversion in Sutton to fall within permitted development.

This ensures the greatest chance of gaining planning permission for attic conversions, without unnecessary delays or issues.
