Insurance for Builders and Building Firms in Wells

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

A builder in Wells is not doing the same job as a builder on a new estate outside Bridgwater. The city's core is dense with listed buildings, the cathedral and its green sit at the centre of everything, and a large share of the domestic and commercial work that comes up is repair, extension and alteration of old fabric rather than clean new-build. None of that is a reason to pay over the odds for insurance — but it is a reason to make sure the policy you buy actually matches the work you do. Apex Insurance Brokers is a Bristol-based broker, and we arrange cover for building firms and sole traders across the UK, including Wells — we don't have an office in the city, and we won't pretend otherwise. What we can do is place the risk properly with insurers who understand heritage work.

Why does damage on a Wells job cost more to put right?

The question that should drive your public liability limit is not "what does a typical claim cost?" but "what would it cost to reinstate the thing I'm working next to?" In a city where the centre is largely listed, the answer is uncomfortable. Damage to a listed building generally has to be made good on a like-for-like basis — matching stone, traditional lime mortars, joinery made to pattern, specialist conservation trades — and the conservation officer, not the loss adjuster, has a say in what "repaired" means. A dropped scaffold pole or a burst pipe that would be a nuisance claim in a 1990s house can become a six-figure reinstatement exercise against medieval or Georgian fabric.

Two practical consequences. First, a £1m public liability limit that looks generous for general domestic work may be thin for a firm regularly working on or beside listed property in Wells; £2m–£5m is worth discussing. Second, check whether your policy carries any restriction or condition around heritage or listed-building work at all — some tradesman policies do, and it's the kind of clause nobody reads until a claim is declined.

Hot works and old buildings: the condition that actually bites

Almost every contractors' policy carries a hot works condition — permits, fire watches, clearing combustibles, keeping extinguishers to hand. In a modern building it's an administrative box to tick. In a timber-framed or thatch-adjacent property in a historic core, it's the condition insurers will examine line by line after a fire, because old buildings burn differently: voids, dry timber, and no fire-stopping between elements. If your work in Wells involves any torch-applied roofing, grinding, soldering or welding on older fabric, follow the permit procedure to the letter and keep the paperwork. Breaching a hot works condition is one of the few reliable ways to turn an insured loss into an uninsured one. Where a specification allows it, pricing the job with cold-applied alternatives removes the exposure entirely — and some heritage clients will insist on that anyway.

What cover does a sole trader in Wells actually need?

Start with what the law requires, which is less than most people assume. If you employ anyone — including casual labour, and in many cases labour-only subcontractors — Employers' Liability insurance is compulsory under the Employers' Liability (Compulsory Insurance) Act 1969, normally at £5m minimum (most policies are written at £10m). Public liability, by contrast, is not a legal requirement. It is, however, a practical one: main contractors, local authorities and the estates teams that manage historic properties will not let you on site without it, and heritage clients in particular often specify minimum limits in the contract. Genuinely self-employed subcontractors working under their own direction usually fall outside the EL requirement, but the employed/self-employed line is drawn on the facts, not the invoice — if you direct someone's work and supply the materials, treat them as an employee for insurance purposes and tell your broker.

Beyond liability: contract works cover for the job itself while it's unfinished, own plant and hired-in plant, and tools. On tools, be honest about overnight storage. Central Wells is a compact medieval street pattern — tight access, limited parking, and often no secure compound on smaller domestic jobs — which in practice means tools living in the van. Most policies exclude or restrict overnight theft from unattended vehicles unless specific conditions are met, so check the wording matches how you actually work rather than how the proposal form assumes you work.

Contract works and the like-for-like problem

Contract works insurance covers the work in progress — if a storm or fire wrecks a half-finished extension, the policy pays to redo it. On heritage jobs the same reinstatement logic applies as with liability: redoing work in traditional materials with specialist labour costs materially more than the contract value might suggest, and lead times on matching stone or purpose-made joinery stretch the period of any delay. Set the contract works sum insured against the realistic cost of reconstruction, not the price you quoted, and if you take on larger alteration contracts, ask whose policy is meant to respond — JCT-style contracts allocate insurance responsibility between employer and contractor differently depending on the option chosen, and on work to existing structures it's frequently the client who must insure the existing building while you insure the new works. Getting that allocation wrong is a classic uninsured gap.

Working around the cathedral and the tourist year

The cathedral green and the streets around it draw visitors year-round, and that pedestrian density is itself an underwriting fact. Scaffolding, deliveries and skips in busy, narrow public spaces raise the frequency end of the public liability risk — slips, strikes from falling objects, damage to parked vehicles — quite apart from the severity end that the listed fabric creates. Licences for scaffolds and skips on the highway typically require evidence of public liability at specified limits, so keep your certificate current and to hand. If a contract requires you to name the client or principal on your policy or waive subrogation, send the wording to your broker before you sign, not after.
