Britain's biggest five builder groups get their own detailed guides — but they only build around half of the country's new homes. This page covers the rest of the top 30–50: who builds where, which brands belong to which group, and the snagging rights that apply whoever's name is on the hoarding.
Search by builder or brand name — sub-brands of the big five groups (Redrow, Linden Homes, Charles Church, Ashberry…) point you to the detailed guide for their parent group.
These five groups build roughly half of the UK's new homes — each has a dedicated guide to its brands, aftercare route and warranty.
Large builders delivering thousands of homes a year across multiple regions. Expect a structured customer care team per development and a formal, written snag-reporting route.
London, Birmingham and the South
Apartment-led regeneration specialist — snag your own plot as normal, and report communal-area defects (lobbies, lifts, landscaping) to the managing agent as well as the developer.
England and Wales
One of the UK's largest family-owned housebuilders.
Scotland, northern England and the Midlands
Scotland, the Cotswolds and southern England
Premium, detached-led developments.
North of England, the Midlands and Scotland
Partnerships builder — many sites mix private and affordable homes. Private buyers keep the standard two-year defect rights either way.
Southern England and the Midlands
Scotland, the North East, Yorkshire and the Midlands
North of England and the Midlands
Low-cost homes, often on regenerated brownfield land.
UK-wide
The housing arm of Morgan Sindall Group, frequently building alongside councils and housing associations.
Aberdeen to the South West; founded in the Isle of Man
The Midlands and the South
London and the South East
Builds own-brand schemes plus joint ventures with housing associations.
Buying a flat changes the snagging picture slightly: your two-year defect rights cover your apartment, while communal areas are put right through the building's management company — report defects in both.
London and the South East
London and the Home Counties
Large-scale London riverside developments
On big phased schemes, ongoing construction next door is normal — but noise, dust and damage to your finished home are still reportable.
Strong local builders delivering hundreds to a few thousand homes a year. Aftercare teams are smaller and often more direct — the same written, photographed snag list works even better here.
East Midlands and South Midlands
Cumbria, the North East, North West and southern Scotland
Yorkshire and the East Midlands
North West, South West and the Severn Valley
North West and the Midlands
Yorkshire and the North Midlands
North West, Yorkshire and the South
Part of the Emerson Group.
Suffolk, Norfolk, Essex and Cambridgeshire
Central England, the West and the South West
The warranty structure is the same across the UK — a builder defects period followed by structural cover — so your snag list works identically north of the border and in Wales.
Across Scotland
North Wales, Cheshire and the North West
Retirement apartments are usually leasehold with a house manager on site — but the developer is still responsible for defects in your apartment during the builder warranty period. Communal snags go through the management team.

Can't find your builder? You're still covered.
Your snagging rights come from your warranty and contract, not your builder's size — the two-year defect period and the reporting playbook below apply to every UK new build.
Regions, brands and group structures change over time — your reservation agreement, completion pack and warranty documents are always the source of truth for your home.
New-build snagging rights don't scale with the size of the builder. Whether your home came from a FTSE-listed group or a two-site regional firm, the same framework of deadlines decides whether defects get fixed at the builder's expense:
Chips, scratches, dents and cracked glass are easiest to dispute before furniture has been through the door. Inspect early — ideally in the empty house — and report cosmetic damage in writing within about 7 days of completion.
For two years from legal completion, the builder — whichever name is on the hoarding — is responsible for putting right defects caused by faulty workmanship or materials, at no cost to you. Keep one running, dated, photographed list.
After the builder period, your warranty provider (NHBC, Premier Guarantee, LABC, Checkmate, ICW or similar — your completion pack names yours) insures against major structural defects to year ten.
Aftercare teams differ; the process that gets snags fixed doesn't. Five steps, whoever your builder is:
Your reservation agreement and completion pack name the customer care contact for your development, your warranty provider and policy number. Note them before you need them.
Walk the home room by room — our free snagging checklist covers what to look for — before the removals van arrives if you can. Photograph everything, even the small stuff.
One itemised, dated, photographed list sent by email beats a dozen doorstep conversations with the site manager. Every later chase and escalation is built on this paper trail.
Builders registered with the New Homes Quality Code are expected to resolve reported snags within around 30 calendar days. Tick off what gets fixed; chase what doesn't, in writing.
If your builder is NHQC-registered, the New Homes Ombudsman Service is free. If not, your warranty provider runs its own dispute resolution service. Both expect exactly the evidence trail you built in steps 2–4.
For the inspection itself, work through our room-by-room snagging checklist, follow the completion-day plan for the first week, and see the new-build warranty guide for how your cover changes across the ten years.
SnagBoss walks you through your home room by room, attaches a photo to every defect, and produces the dated, professional report that any builder's customer care team acts on.
