Loft conversion in Blackwater

Looking for a loft conversion specialist in Blackwater doesn’t need to be complicated. We can help you find checked loft conversion builders and companies who cover your local area.

  • Search our website for loft conversion companies in Blackwater and contact them directly.

  • Try our quick and easy request a quote feature. If you’re short on time, give us the details of your job and we’ll forward these to three loft conversion builders. They’ll then get in touch, either asking for further information or to arrange a quote.

What types of loft conversion are available?

Common loft conversions include:

  • Dormer: Adds extra floor space by extending the roof vertically
  • Velux: Uses roof windows without major structural changes
  • Mansard: Involves steepening one roof slope to maximize space
  • Hip-to-Gable: Converts a sloped roof into a vertical wall to create more space

How much does a loft conversion cost?

The average loft conversion in the UK costs around £40,000, though this depends on the type of conversion, size of the loft, roof structure, and your location.

For example, dormer conversions typically cost around £45,000, while Velux conversions start at about £27,500.

Additional costs may include electrics, flooring, bathrooms, and underfloor heating.

Do I need planning permission?

Not all loft conversions require planning permission. Many conversions fall under permitted development rights.

However, you will need permission if you live in a listed building, a conservation area, or plan to alter the shape or height of your roof.

It’s always worth checking with your local planning authority to be on the safe side.

How long does a loft conversion take?

Timescales vary depending on the type of conversion. As a rough guide:

  • Velux conversions: 4–6 weeks
  • Dormer conversions: 10–12 weeks
  • Mansard conversions: 8–10 weeks
