Bolton's housing stock is a real mixed bag, which is exactly why the builder you need in Astley Bridge might not be the right fit for a job in Farnworth or Horwich. You've got rows of Victorian terraces around Deane and Daubhill with solid stone foundations but often dodgy old chimney breasts, plus a good number of 1930s semis out towards Bromley Cross that tend to need cavity wall attention or roof repairs. Then there's the newer estates near Westhoughton and Lostock, where extensions and loft conversions are the more common ask. Add in Bolton's clay-heavy soil in places, which matters when you're talking foundations or an extension footing, and you can see why local knowledge counts for a lot here, not just a general trade certificate.

The builders featured on this page come from public business listings, and we've ranked them by their review rating and how many reviews they've built up over time, with a small boost given to those who have a working website and a contactable phone number. We also read through each business's homepage to check that building work, rather than something adjacent like plastering or roofing alone, is genuinely their main trade. That step keeps unrelated businesses off a page that's meant specifically for builders. Any listing showing as permanently closed gets stripped out automatically, so you're not wasting time ringing round dead numbers. Where you spot a Trust Verified badge next to a business, that firm has gone further and passed our fuller verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. Our How We Verify page sets out exactly what that involves. For any business without the badge, those checks haven't been done by us, so it's worth doing your own homework before you book anyone in.

Before you commit to a builder, ask to see their public liability insurance certificate and, if the job involves anything structural, proof they're familiar with Building Control requirements for Bolton Council. For bigger jobs like extensions or loft conversions, get a written quote that breaks down materials and labour separately, and always get at least two or three quotes so you can spot anyone pricing wildly out of step. Ask for photos of recent, similar jobs nearby, ideally something within a few miles so you know they understand local ground conditions and roof types. It's also worth asking how they handle waste removal and skip hire, since that can quietly add a few hundred pounds to a job if it's not agreed upfront.
How We Select & Rate The Best Builders in Bolton

Ranking is driven primarily by each business's review rating and review count from public business listings, with a small lift given to those showing a working website and phone number. We check every business's homepage to confirm building work is what they primarily offer, which keeps unrelated trades off this page. Listings flagged as permanently closed are removed automatically. Businesses marked Trust Verified have gone further, passing our full 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 complete list. Other businesses haven't been independently verified by us, and appearing on this page isn't an endorsement. Always carry out 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 builder cost in Bolton?
It varies hugely with the job. A small kitchen or bathroom refit might run from £3,000 to £8,000, while a single-storey rear extension in Bolton typically lands somewhere between £25,000 and £45,000 depending on size, finish and whether you're changing drainage or the roofline. A loft conversion with a dormer is often £35,000 to £50,000. Labour-only day rates for a general builder around Bolton tend to sit between £180 and £280, though that shifts with experience and demand. Always get two or three quotes before deciding, since prices for the same job can differ by several thousand pounds between firms.
Do I need planning permission for an extension in Bolton?
Many single-storey rear extensions fall under permitted development if they stay within size limits, generally up to 6 metres for an attached house, but two-storey extensions, anything close to a boundary, or work on a listed building usually needs full planning permission from Bolton Council. It's worth checking with the council's planning portal or asking your builder to confirm before work starts, since building without the right permission can mean costly changes later or trouble selling the house down the line.
How long does a loft conversion or extension take in Bolton?
A straightforward loft conversion usually takes six to eight weeks once it's started, though scaffolding, structural steel work and Velux installation can push that out if there are delays getting materials. A single-storey extension often takes eight to twelve weeks from breaking ground to a finished, decorated space. Weather can slow groundwork in the wetter months, and anything involving party wall agreements with neighbours can add a few weeks upfront before building even begins.
What should be included in a builder's quote?
A proper quote should break down labour, materials, waste removal and any subcontracted work like electrics or plumbing separately, rather than giving one lump figure. It should specify the exact spec of materials, for example brick type, insulation grade, or the make of any windows and doors, so you're comparing like for like between quotes. Ask whether the price includes scaffolding hire, skip hire and making good to neighbouring walls or gardens, since these are common extras that catch people out later.
Should I use a local Bolton builder or a bigger regional firm?
A local builder based in or near Bolton usually knows the area's soil conditions, common house types and the local Building Control team, which can smooth things along. They're also easier to check up on through neighbours or previous customers nearby. Bigger regional firms sometimes have more capacity for large projects or tighter timescales, but can be pricier and less flexible on small tweaks. For most extensions, renovations and loft conversions, a well-reviewed local firm tends to be the more practical choice.
How do I check a builder is right for my job before booking?
Ask to see their public liability insurance certificate and, if relevant, evidence of any trade accreditations for the specific work involved. Request contact details for two or three recent customers, ideally for similar jobs, and actually ring them. Look at how long they've been trading and read through their review history for patterns, not just the star rating. Check whether they're a registered company with Companies House if that matters to you, and get everything, including start dates and payment stages, agreed in writing before any work or deposit changes hands.
