Anyone happy to share how much you want they've paid for a single storey extension in the last 6 months or so?

We're hoping to get a single storey extension, approx 6m x 3m. I'd really appreciate anyone who is willing to share the size and cost of their recent extension with me. (Context being DH is convinced that quotes should be cheaper than we've had, I'm less convinced and feel the (high) quotes are just a reality of the current market). Current quotes sit around £68k mark and we're in a popular area of South Wales.

Approx 95k, 5x3m. Included a new kitchen, downstairs WC, exterior power, knocking together upstairs bathroom & WC to make 1 room and unexpected new electrical works to most of the downstairs.
Outer London

Thank you, can I ask did the £95k include the cost of the new kitchen too? (We'll have to fund one on top the quoted build costs!)

Yes, but not the cost of the new flooring throughout the house

Single storey 6.5m wide x 4m long (2022) peak inflation material costs. Included 4 keylite windows and 8ft bi fold. Gable roof. £45k (West Midlands - local builder)

Watching with interest as we've had quotes of 25-30k for a refresh of our 3.5m2 conservatory!

CatStoleMyChocolate · 07/02/2025 23:18

If that quote is to a plaster finish including VAT but not including decorating, flooring, or the actual kitchen - that sounds about right to me. We paid £75k for about the same size in 2022, Home Counties/East of England. Pre-VAT, it was just over £3k per square metre.

In our case, the kitchen units, appliances, worktops and lights came to about £25k - that was a DIY Kitchens kitchen (solid painted wood) so we could have spent quite a bit more.

Not sure how helpful this is, but we’re in the final stretch of ours (West Midlands). For a roughly 6x5m pitched-roof extension, it’s coming in (including architect’s drawings, structural calcs, drain survey, planning fees, flooring, lighting, heating, kitchen, x4 Velux roof lights, Crittall-style steel French doors and windows, and VAT) around £130k. However… that includes moving the kitchen to the previous rear living room, adding in a downstairs loo, and converting the original small kitchen to a utility and a pantry. So a lot of messy reconfiguration work too. The builders quote (inc VAT) was £72k, which included everything to second fix (bar the flooring, kitchen/pantry/utility/wc fixtures and fittings, and painting), but didn’t include the French doors and windows as we wanted to source those ourselves.

3k per square metre also in South Wales

mummabubs · 08/02/2025 09:58

Thank you everyone who's shared so far, it's really helpful. DH has sent me a CheckATrade article that states the average cost of an extension this year is £48k, but I don't know whether that includes VAT and also I've yet to find a single person who has paid anywhere close to that! 🤷🏻‍♀️

Yup, our quote is exactly as you've guessed. I think it sounds about right too, I guess we'll have to see where other quotes come in at over the next few days.

We would like to make our living room a bedroom and extend out 3m2 to back garden to make a living room.

What do you mean by a refresh?

FriendlyWerewolf · 11/02/2025 21:27

Small extension of kitchen for a utility room, 3x5m. Quotes vary between £35-45k. I think £2.5-3k per sqm is fairly standard these days wherever you are in the country.

ThrillsAndSpills2025 · 11/02/2025 21:34

Also, don't forget if you are budgeting add on at least 10pc for unexpected spend on top of a quote

Gloriousgardener11 · 11/02/2025 21:35

We’ve been quoted 50k for a 3mx3m conservatory, solid roof with two glazed panels.

kitchenplans · 11/02/2025 21:36

2 years ago and SE. 7.5mx2.1m.

Total cost £95k, of which build cost was £65k. Kitchen & utility £15k, flooring £3k, architect and planning £2k

MissAtomicBomb1 · 11/02/2025 22:43

@LindaDawn
Insulated Warm roof with x2 velux, new frames & glass, bifolds, plastering/spotlights.
The price includes a few other bits plus budgeting for new flooring & decorating.
It's pretty much a new conservatory bar keeping the existing dwarf walls.
