How Long Does a Loft Conversion Take? A Realistic Timeline

One of the most common questions we get asked is: 'How long will my loft conversion take?' The honest answer is that it depends on the type of conversion, the complexity of the project, and whether planning permission is required. Here's a realistic breakdown of what to expect.

Stage 1: Survey and Design (1–3 weeks)

After your free initial survey, we produce structural drawings and, if required, an architectural design. This stage typically takes 1–3 weeks depending on the complexity of the project.

Stage 2: Planning and Building Regulations (4–8 weeks)

If planning permission is required, you'll need to allow 8 weeks for the local authority to process the application. Building Regulations approval typically takes 2–4 weeks. If only Building Regulations are needed (which is the case for most conversions), this stage is much quicker.

Stage 3: Construction (4–12 weeks)

The construction stage varies significantly by conversion type: Velux conversions take 4–6 weeks; rear dormer conversions take 6–8 weeks; hip-to-gable conversions take 8–12 weeks. These timescales assume a standard single-room conversion with a basic ensuite.

What Can Delay a Loft Conversion?

Common causes of delays include: waiting for planning permission, adverse weather during the roof work stage, changes to the specification mid-project, and supply delays for specialist materials. A well-managed project with a clear brief and fixed specification will always complete faster.
