How much does a loft conversion cost in Nottingham? (2026)

6 min read

A loft conversion is often the best-value way to add a bedroom and value without losing garden space — but the cost depends enormously on the type. Here's an honest 2026 guide to loft conversion costs in Nottingham, broken down by conversion type.

Typical loft conversion costs by type

A Velux (roof-light) conversion, where the existing roof shape stays and you just add windows, floor and a staircase, is the cheapest — usually around £20,000–£35,000 in Nottingham, but only works if you already have enough head height.

A dormer conversion, which builds out a box from the roof to add headroom and floor space, is the most popular and typically runs £35,000–£60,000. A hip-to-gable (often combined with a rear dormer) replaces a sloping side with a vertical gable wall and lands around £45,000–£70,000+.

Add roughly £5,000–£15,000 if you want an en-suite, and remember finishes, fitted wardrobes and high glazing sit on top of the shell cost.

What drives the price

The conversion type and how much the roof structure has to change — Velux keeps the roof, a dormer adds structure, and hip-to-gable rebuilds part of it.

Head height and the existing roof: if there isn't enough height, the job gets much more involved (and occasionally isn't viable without lowering ceilings below). Steel beams, the new staircase and any structural work all add cost.

Building regs, party-wall agreements with neighbours on a terrace or semi, fire-safety requirements (a loft bedroom changes escape rules), and professional fees for drawings and a structural engineer.

Getting an accurate quote

Loft prices vary hugely, so get a builder or loft specialist to assess head height and roof structure on site before quoting — paper estimates without a visit are unreliable. Ask for an itemised, written quote with a stage-payment schedule, and confirm building regs sign-off is included.

Get two or three quotes against the same drawings. Posting the job on Rank My Builder gets it in front of verified local builders with reviews and recent local work you can check.

FAQs

Do I need planning permission for a loft conversion?

Many loft conversions fall under permitted development, but dormers and hip-to-gables have volume limits, and conservation areas and some house types are excluded. Always check with Nottingham City Council or your local planning authority — your builder or architect can advise.

How long does a loft conversion take?

A typical dormer conversion is around 6–10 weeks on site. A simple Velux conversion can be quicker; a hip-to-gable with an en-suite takes longer. Your builder should give you a stage-by-stage schedule up front.
