Options to consider in Warwick

Shower room in the loft

Most conversions include a shower room or en-suite. Placing it close to the existing soil stack keeps the waste run short and reliable. Because of the sloping ceilings, the shower goes where the head height is, often within the dormer, while the WC and basin can sit under the lower parts of the roof.

Rear dormer conversion

A box-shaped extension built out from the rear roof slope, with vertical walls and a flat roof, giving full standing height across most of the room. It suits semis and terraces because it adds the most usable space for the money. Under permitted development it must be set back from the eaves and stay within the volume allowance.

Guide prices for Warwick

Expect to budget between £22,000 and £72,000 depending on size and specification in Warwick. A rear dormer with a double bedroom and shower room on a three-bed semi: typically £42,000–£52,000.

Before you book in Warwick

How long does a loft conversion take?

Most take 6–10 weeks on site, with roof-light conversions at the shorter end and hip-to-gable or mansard work at the longer end. Allow time beforehand for drawings, a lawful development certificate or planning decision, and party wall notices, which need two months on a semi or terrace. We plan the start date around those periods so nothing is left waiting.

How do I book a survey in Warwick?

Send the form on this page, use the guide-price tool or call 0800 088 6248 free. We'll ask a few questions about your loft conversion and arrange a time to visit.

Which certificates will I have once the loft is finished?

You'll receive the building control completion certificate, an electrical installation certificate, and your lawful development certificate or planning decision. Manufacturers' guarantee terms for roof windows, roof coverings and other products are set out in your quote. Keep these documents safe, because a buyer's solicitor will ask for them. If you'd like our current insurance details, ask with your quote.

Does Warwick District Council need to approve my loft conversion?

Usually building control, and sometimes planning. Warwick District Council is the planning authority for Warwick; Building Regulations approval comes from its building control team or a registered building control approver. We'll tell you which applies after the survey.
