Builders' Insurance in Bridgwater: Cover for Firms and Sole Traders

Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited · Last reviewed 2026-08-08

Bridgwater is not a quiet market town where a builder's year is all extensions and re-roofs. The Hinkley Point C build has pulled thousands of construction workers, hauliers and specialist trades into the area, and that ripples out into everything — the subcontract packages local firms bid for, the demand for accommodation and refurbishment work in town, even how busy the roads are when you're moving plant. At the same time, the town sits on the edge of the Somerset Levels beside the tidal River Parrett, in a landscape that flooded badly in the winter of 2013–14 and that insurers have long memories about. Neither of those things makes insurance impossible. Both of them change what a sensible policy looks like.

What does Hinkley actually change for a Bridgwater builder?

Even if you never set foot inside the Hinkley Point site itself, the project changes the paperwork. Large infrastructure schemes run on tiered supply chains, and the contracts that flow down those tiers — groundworks, fit-out, welfare units, fencing, logistics — typically arrive with insurance schedules attached. It's common for main contractors on major projects to require public liability limits of £5 million or £10 million before you can even be considered, along with evidence of employers' liability and, for anything with a design element, professional indemnity. If your current policy carries a £1 million or £2 million liability limit because that's what your domestic work needed, you may find the limit — not your price or your workmanship — is what keeps you off the tender list.

Two things are worth checking before you chase that kind of work. First, height and depth limits: many standard tradesman policies restrict work above a certain height or below ground level, and infrastructure-adjacent packages can breach both. Second, the definition of your business activities on the policy schedule. If it says "general building — private dwellings" and you're pouring concrete on a compound for a tier-two contractor, you have a problem on the day you claim, not the day you sign.

The project also feeds the town's ordinary workload. A large incoming workforce needs somewhere to live, which has meant refurbishment, conversion and landlord work for local firms. Conversion work brings its own wrinkles — JCT-style contract conditions, requirements to insure existing structures as well as the new works, and clients who expect certificates before you start.

Building beside the Levels: how flood risk shows up in your cover

Everyone in Bridgwater knows the Levels flood; the question is what that means for a builder's policy rather than a homeowner's. Three places it bites:

Contract works. A half-built extension or a stripped-out ground floor in a low-lying part of town is far more vulnerable to water than a finished building. Contract works cover protects the job itself — materials fixed and unfixed — but on sites in recognised flood risk areas, insurers may apply higher excesses or specific conditions for storm and flood. Know what those are before the works start, not after the Parrett has been over its banks.

Plant and materials storage. Where does your kit sit overnight and over the weekend? A compound or yard on low ground carries a genuine flood exposure for owned and hired-in plant. Hired-in plant is a particular trap: hire agreements usually make you liable for the machine while it's in your care, floodwater included, and continuing hire charges can run while it's being repaired.

The work itself. Flood-hit and flood-risk properties generate work — drying out, reinstatement, resilient repairs, flood doors and barriers, raised electrics. If you're advising a client on how to make a property more resilient, or specifying materials for that purpose, you're edging into design-and-advice territory where professional indemnity cover starts to matter alongside public liability. Get a repair specification wrong on a property that floods again and the claim will come to you.

Sole trader with a labourer on Fridays — do you need employers' liability?

Almost certainly yes. Under the Employers' Liability (Compulsory Insurance) Act 1969, employers' liability insurance is a legal requirement once you have employees — and for insurance purposes, "employees" usually includes labour-only subcontractors: anyone working under your direction, using your materials, paid for their time rather than a fixed price. That catches a lot of Bridgwater sole traders who think of themselves as one-man bands but regularly bring in a mate for second-fix or a labourer for muck-away. Bona fide subcontractors who work to their own methods with their own insurance are treated differently, but you should be collecting evidence of their cover, because main contractors and loss adjusters will ask for it.

Public liability, by contrast, is not required by law. In practice it's required by almost everything else: site rules, subcontract conditions, local authority work, and any client who's thought about what happens if a scaffold board comes down on their car. On a project-driven patch like this one, treat it as the ticket to work.

Tools, vans and a town full of construction traffic

A busy construction economy is good for order books and bad for van locks. Tool theft is a nationwide problem for the trades, and a town with this concentration of site work is exactly where a van full of power tools is worth someone's attention. Check three things on your tools cover: whether theft from an unattended vehicle is covered at all, what the overnight conditions are (many policies exclude theft from a vehicle overnight unless it's in a locked building or secure compound), and whether your sum insured reflects replacement-as-new prices rather than what you paid years ago. If a stolen kit means a lost week's work, consider whether your policy can extend to cover the hire of replacement tools so the job keeps moving.
