Most towns can be insured off a postcode and a trade description. Sherborne can’t, and the reason is visible the moment you walk through the centre: almost everything is built from the same warm hamstone, a great deal of it is listed, and the whole place trades on a heritage core anchored by the abbey and the town’s two castles — the medieval ruin and the later house. That combination changes what a sensible insurance programme looks like, whether you run a shop, a café, a professional practice or a building firm.
This is the question that catches Sherborne businesses out most often. Buildings insurance pays to reinstate your premises — and if your premises is a listed hamstone building, reinstatement does not mean modern blockwork with a rendered finish. It means matching stone, and usually the methods and materials the conservation officer will insist on: lime mortar rather than cement, like-for-like joinery, traditional roof detailing. Listed building consent adds time as well as cost, because you cannot simply start rebuilding the way you could with a modern unit.
The practical consequence is that a sum insured based on a standard rebuild-cost estimate, or worse on market value, is very often too low for a listed hamstone property. If you are underinsured, the “average” condition in most policies lets the insurer reduce every claim payment in proportion — including small ones. For listed premises we generally recommend a professional reinstatement cost assessment rather than an indexed guess, and telling the insurer clearly that the building is listed so the policy is rated and worded for it from the start. Tenants aren’t off the hook either: check what your lease makes you responsible for, particularly shopfronts, glass and internal alterations in an older building.
Business interruption cover pays your lost income while damage is repaired — but only for the indemnity period you chose when you bought the policy. Twelve months is the default, and in Sherborne’s conservation-area core it is frequently not enough. Between listed building consent, sourcing matching hamstone, and finding contractors with genuine conservation experience, a serious fire or escape-of-water loss in an old building can take well over a year to put right. If your indemnity period runs out before the scaffolding comes down, the rest of the loss is yours. For businesses in the historic centre we usually talk about 24 or 36 months, and about basing the sum insured on realistic projected turnover, not last year’s accounts.
There’s a second Sherborne-specific angle: the abbey and the castles bring visitors, and visitor towns have seasons. If your busy months carry the year, an interruption that lands just before them costs far more than the same interruption in a quiet spell. That should shape both your indemnity period and your sum insured — it’s exactly the kind of detail a broker should be pressing you on before renewal, not after a claim.
Public liability insurance is not required by law — unlike employers’ liability, there is no statute compelling you to buy it. In a town whose economy leans on visitors drawn by the abbey and the castles, it is close to essential anyway. Uneven historic floors, steps into old shop units, pavement displays and café tables on narrow streets all put members of the public in close contact with your business, and a single injury claim can run to sums no small firm wants to meet from its own pocket. Landlords, event organisers and commercial leases in the town will usually require evidence of cover in any case, so in practice the question is not whether to carry it but whether your limit — £1m, £2m, £5m or higher — matches what your contracts and your footfall actually demand.
A large share of the building work generated in and around Sherborne is repair, extension and conversion of period hamstone property rather than new build. If you’re a builder, carpenter, roofer or stonemason working on that stock, say so when your policy is arranged. Insurers rate heritage work differently, and the standard exclusions — heat work, depth limits, work on buildings over a certain age or height — bite hardest on exactly this kind of job. Getting hot-works conditions, contract works cover and any height or age restrictions right on day one matters far more here than on a modern housing site. Tool theft from vans is a further live issue for rural Dorset trades covering scattered jobs; check overnight theft conditions and any requirement for forced-entry evidence before you rely on the cover.
And one legal point that applies to every Sherborne employer, heritage or not: if you have staff — including casual, seasonal or part-time help — employers’ liability insurance is compulsory under the Employers’ Liability (Compulsory Insurance) Act 1969. That is the one cover the law requires; most of the rest is driven by your contracts, your lease and your appetite for risk.
Apex Insurance Brokers is based in Bristol and arranges commercial insurance for clients across the UK, Sherborne included — we don’t claim a desk on the high street, and you don’t need us to have one. What you do need is a broker who asks the right questions before placing the risk: Is the building listed? What would matching hamstone reinstatement really cost? How long would consent and specialist repair genuinely take? Which of your contracts demand what liability limits? Those answers, documented properly, are the difference between a policy that responds and one that argues.
