Business Insurance in Yeovil: Cover for a Helicopter Town

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

Yeovil is one of the few towns in Britain where helicopters still roll off a production line, and they have done for decades — from Westland to the Leonardo Helicopters operation the town is known for today. The supply chain that has grown up around that work — precision machine shops, fabricators, surface-treatment and finishing firms, tooling specialists, calibration labs, hauliers — is what makes the local economy tick. Add a town-centre core built in honey-coloured hamstone, much of it listed or sitting within a conservation area, and you have a place whose insurance questions are genuinely different from the market towns around it. Apex Insurance Brokers Limited is a Bristol-based broker arranging cover for businesses across the UK, including Yeovil. We do not have an office in the town and will not pretend otherwise; what we do have is a clear view of why cover here needs a closer look than a price-comparison form will ever give it.

Does your liability policy actually cover aerospace work?

This is the question that catches Yeovil businesses out more than any other. Many standard commercial combined policies carry an aviation exclusion within the products liability section — wording that removes cover for products intended for use in aircraft. For a machine shop in most towns, that clause is irrelevant. In Yeovil, where a batch of machined components can quite plausibly end up in an airframe or a transmission assembly, it can quietly hollow out the policy you are relying on.

If you supply into the aerospace chain, even at second or third remove, the honest starting point is a conversation about what you make, who buys it and where it goes. Depending on the answers, you may need aviation products liability arranged deliberately, rather than a general products extension that excludes the very work paying your wages. The contractual side matters just as much. Prime contractors and tier-one suppliers flow requirements down the chain: specified minimum liability limits, professional indemnity wherever you carry design responsibility, and increasingly evidence of cyber security and cyber insurance before you are admitted to an approved-supplier list. A broker's job is to make sure the policy you buy matches the contracts you have signed, not just the trade description on the schedule.

One dominant customer: the business interruption problem

Supply-chain economies concentrate risk. If a meaningful share of your turnover traces back, directly or indirectly, to one customer or one site, your business interruption exposure is not only about a fire at your own premises. Ask about customers' and suppliers' extensions on your BI cover, and think hard about the indemnity period: replacing specialist machinery, requalifying processes and winning back approved-supplier status after a major loss takes far longer than a standard twelve months. High-value CNC machinery deserves its own attention too — realistic reinstatement values, breakdown cover, and honest lead times for replacement equipment all belong in the conversation before renewal, not after a claim.

Hamstone looks lovely on a valuation — until you have to rebuild it

The other thing that sets Yeovil apart is what its older buildings are made of. Hamstone, the golden limestone quarried at Ham Hill just outside the town, gives the heritage core its character, and a good number of those buildings are listed or sit within conservation areas. That has a very practical consequence: the sum insured. A hamstone building must generally be reinstated in matching materials using traditional methods — stone from a limited local source, lime mortar, masons who know the material. Rebuild costs therefore bear little relation to market value, and even less to what a standard rebuild calculator suggests. If your sum insured is too low, the average clause lets insurers reduce every claim proportionately, not just a total loss. For owners and tenants of period premises, a professional reinstatement valuation is one of the cheapest pieces of risk management available. And because listed building consent and stone-matching slow repairs down, business interruption indemnity periods on heritage premises should usually run to twenty-four months or more rather than the twelve-month default.

Trades and contractors: what is required, and what is merely expected

If you employ anyone — full-time, part-time, casual or labour-only subcontractors — employers' liability insurance is a legal requirement under the Employers' Liability (Compulsory Insurance) Act 1969, with a minimum limit of £5 million. Public liability, by contrast, is not required by law. In practice it is demanded almost everywhere: local authorities, principal contractors and commercial clients will not let you on site without it, and where secure manufacturing sites are involved, clients may ask for higher limits and documented compliance before contractors get on site. Beyond liability, the usual working realities apply: tools stored in vans overnight (check the theft conditions and any forced-entry requirement), hired-in plant, and contract works cover for jobs that go beyond repair and maintenance.

The rest of the town still needs looking after

Not everything in Yeovil is aerospace or hamstone. Shops, cafés, salons, gyms, offices, vets, landlords and professional practices need the same well-built cover as anywhere else — property, liability, business interruption and, increasingly, cyber, which carries more weight here than in the average town because defence-adjacent supply chains push security expectations onto even the small firms that touch them. Professional firms feel the local shape of things too: accountants advising manufacturing clients and architects specifying repairs to listed hamstone properties carry professional indemnity exposures formed by exactly the features described above. The point of using a broker is that none of this gets handled generically — your cover should reflect what your business actually does, in the town where it does it.
