Woking's a mixed bag when it comes to housing, and that shapes what builders here actually spend their time doing. You've got the Victorian terraces around Maybury and Goldsworth Park, 1930s semis in St John's, and newer estates out towards Horsell and Knaphill where loft conversions and side-return extensions are the bread and butter. Older properties often mean solid brick walls, older drainage runs and the odd surprise once plaster comes off, so a lot of local builders have learned to price in some flexibility for that. Proximity to London also means plenty of homeowners extending rather than moving, given how competitive the property market can be, so single-storey rear extensions and loft conversions with dormer windows are common jobs across the postcode.

The businesses featured on this page were pulled from public business listings and ranked mainly by review rating and how many reviews they've built up, with a small boost given to those showing a working website and phone number. We also checked each business's homepage to confirm building work is genuinely what they do day to day, which stops general handymen or unrelated tradespeople slipping onto a builders list. Any listing flagged as permanently closed gets removed automatically. Where you spot a Trust Verified badge, that business has gone through our fuller verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company details. Our How We Verify page sets out exactly what that involves. For businesses without the badge, those checks haven't been done by us, so it's worth doing them yourself before you commit to anything.

Before hiring, ask to see proof of public liability insurance and, if the job touches gas or electrics, confirmation the relevant tradespeople are Gas Safe registered or NICEIC certified. Get a written quote that breaks down labour, materials and any provisional sums for unknowns like rewiring or structural work. Ask how they handle building regulations sign-off, particularly for extensions or loft conversions, and whether that's included in the price. It's worth getting two or three quotes for anything over a few thousand pounds, not just to compare cost but to see how each builder explains the job and timescales. A big gap between quotes usually means something's been read differently, so ask why.
How We Select & Rate The Best Builders in Woking

Rankings are based on review rating and review count from public business listings, with a small lift given to businesses showing a working website and phone number. We check each business's homepage to confirm building work is what they primarily offer, keeping unrelated trades off the page. Listings flagged as permanently closed are removed automatically. Businesses marked Trust Verified have additionally passed our fuller verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information; see our How We Verify page for the full list. Other businesses haven't been independently verified by us, and appearing here isn't an endorsement. Always do your own checks before hiring.

Recommended and Featured listings are paid placements, so a business's fee affects whether and where it appears. Every other listing is ranked on rating and review count from third-party business listings. How we rank & verify →

Frequently Asked Questions

How much does a builders cost in Woking?
It varies a lot depending on the job. A single-storey rear extension in Woking typically runs from around £1,800 to £2,500 per square metre once you include materials, labour and finishes, so a modest 20 square metre extension might land somewhere between £36,000 and £50,000. Loft conversions with a dormer often start around £40,000 to £55,000 depending on plumbing and roofline changes. Smaller jobs like a new stud wall, rebuilding a garden wall, or fixing brickwork can run from a few hundred pounds to a couple of thousand. Always get two or three written quotes, because prices can differ significantly based on how a builder scopes the job and what allowances they've built in for unexpected issues.
Do I need planning permission for an extension in Woking?
Many single-storey rear extensions fall under permitted development rights, so formal planning permission isn't always needed, but there are limits on size, height and proximity to boundaries. Woking Borough Council's planning department can confirm whether your specific project qualifies, and it's worth checking before any work starts. Even where planning permission isn't required, building regulations approval almost always is, covering things like structural stability, insulation and fire safety. A good builder will know the local rules and can point you towards a planning consultant if your project needs one.
How long does a loft conversion or extension take?
A straightforward loft conversion usually takes six to eight weeks once building regulations approval is in place, though dormer conversions with structural steel work can push towards ten weeks. Single-storey extensions tend to run eight to twelve weeks depending on groundworks and whether you're tying into existing drainage or a stopcock that needs moving. Weather, materials lead times and any changes you make partway through all affect the schedule, so build in some contingency rather than planning around the tightest possible timeline.
Should I pay a deposit before work starts?
A modest deposit, often 5 to 10 percent of the total job value, is normal to secure materials and a start date, but be wary of anyone asking for a large upfront sum before any work has begun. Stage payments tied to completed milestones, such as after groundworks, after the roof goes on, and at practical completion, are a fairer way to structure larger jobs. Get the payment schedule written into your contract so both sides know what triggers each instalment.
What's the difference between a builder and a project manager for a big renovation?
On a large extension or full renovation, some builders act as the main contractor and coordinate electricians, plumbers and plasterers themselves, while others expect you to manage separate trades directly. Clarify this before you sign anything, because it changes both the price and how much of your own time the project will take up. If you're juggling a full-time job, paying slightly more for a builder who manages the whole thing, including scheduling and building control sign-off, often saves a lot of stress.
How do I choose between builders in Woking?
Start by asking to see examples of recent work nearby, ideally jobs similar in scale to yours, and try to visit one in person if the builder agrees. Ask for proof of public liability insurance and, for anything involving gas or electrics, check the relevant tradespeople hold current Gas Safe or NICEIC registration yourself rather than taking it on trust. Look at how long they've been trading and read through their reviews for patterns, not just star ratings, since recurring comments about timekeeping or communication tell you more than a single five-star review. Get a detailed written quote from at least two or three builders, ask how disputes or defects after completion are handled, and check whether they're registered with a trade body like the Federation of Master Builders. Doing this legwork yourself before booking is the best protection you have.
