Workshop insurance

Workshop insurance is bought to protect the place where value is actually made or repaired — the building, the machinery bolted to its floor, the stock waiting to be worked on, and the liability that comes with people, sparks and moving equipment. Most owners buy it as a single package and assume the numbers on the schedule will hold. Where it goes wrong is rarely the headline cover; it is the detail. Plant and stock values that were set years ago and never revisited, a business-interruption indemnity period too short to rebuild and re-tool, hot-works or security conditions that quietly become unmet, and activities the workshop drifted into that were never declared to the insurer. Each of those turns a valid-looking policy into a disputed or reduced claim. Apex arranges workshop cover placed by a named broker who presents the risk properly and keeps the sums insured honest.

Key covers for a workshop

• Buildings and premises — the workshop structure itself against fire, storm, flood, escape of water, impact and malicious damage, whether you own the freehold or hold a repairing lease that puts the reinstatement obligation on you.
• Contents, plant and machinery — fixed and loose machinery, benches, racking, jigs, fixtures and fittings. Values should reflect current replacement-as-new cost, including installation and commissioning, not the depreciated book figure.
• Stock and materials in trade — raw materials, work in progress and finished goods. Seasonal peaks and customers' goods left on site for repair or fabrication both need to be reflected in the sum insured.
• Business interruption — loss of gross profit and increased cost of working while you rebuild, re-source machinery and win customers back. The indemnity period is the single most important figure to get right.
• Public and products liability — injury to visitors, contractors or the public, and damage caused by goods you have made, repaired or supplied once they leave your control — often £2m–£10m, subject to underwriter assessment.
• Employers' liability — legally required once you employ anyone, including apprentices, casual and labour-only staff common in workshop settings, with the £5m statutory minimum widely written at £10m.
• Tools and portable equipment — hand tools, power tools and test equipment against theft and damage, whether kept on site, in a van or taken to a customer's premises for installation or service work.
• Machinery breakdown and deterioration of stock — sudden mechanical or electrical failure of plant, compressors or refrigeration, plus spoilage of temperature-sensitive stock where breakdown causes the loss.
• Goods in transit — materials, tools and finished work while being carried to and from site or between units, a common gap for makers who deliver or install what they produce.
• Money and glass — cash, floats and takings on the premises and in transit, plus fixed glass and signage where relevant to a trade-counter or retail-facing workshop.

What underwriters focus on

A workshop is rated as a property-and-liability risk with a strong emphasis on fire and theft, and the underwriter is pricing the specific way your premises is built, occupied and secured — not a generic “workshop” label. The first thing they look at is construction. A single-storey brick or steel-frame unit with a non-combustible roof rates very differently from one incorporating composite sandwich-panel insulation; where panels are present, underwriters increasingly ask whether the core is mineral wool or a combustible plastic foam, because that materially changes fire spread and total-loss potential.

Occupancy and process are next. The trade carried on inside — woodworking, metal fabrication, engineering, vehicle repair, upholstery, food production — drives the fire load and the liability exposure. Hot works such as welding, grinding, brazing and cutting are a particular focus, and cover is routinely offered subject to a hot-works permit condition and a fire-watch period after work stops. Spray booths, dust extraction, timber and solvent storage, and any use of LPG or oxy-acetylene all attract closer questioning. Combustible waste and its housekeeping matter more than owners expect, because poor waste control is a recurring cause of avoidable fires.

Security governs the theft rating. Underwriters look at the physical protection of the perimeter and openings — locks to a recognised standard, shutters, grilles — and at any intruder alarm, whether it is monitored, and whether high-value tools and stock are removed to a secure store or held in a safe overnight. Where they impose a minimum-security or alarm-maintenance condition, meeting it becomes part of the contract, not a suggestion.

Sums insured are scrutinised because underinsurance is endemic in this sector. Buildings should be on a full reinstatement basis reflecting current build costs, debris removal, professional fees and any uplift for compliance with current building regulations. Plant and machinery should be replacement-as-new including installation, and stock should reflect true peak values. On business interruption, the underwriter wants an indemnity period long enough to source and commission replacement machinery — often the limiting factor after a serious fire. Finally, claims history, management experience, and how fairly and completely the risk is presented under the Insurance Act 2015 all shape both the terms offered and the premium.

Common claims

Fire from hot works or a grinding operation. Sparks from cutting or grinding ignite nearby stock or dust and the fire spreads through the unit. The buildings and contents sections respond to the physical damage, while business interruption covers the lost gross profit and the increased cost of working from a temporary site — subject to any hot-works permit condition being met.

Break-in and theft of tools and plant. Thieves force a roller shutter overnight and remove power tools, test equipment and portable machinery. The contents and tools sections respond, subject to the security and overnight-storage conditions the underwriter attached — a monitored alarm or high-value items in a locked store are frequently required.

Machinery breakdown and stock spoilage. A compressor or a key CNC machine suffers a sudden electrical failure. Machinery breakdown cover meets the repair, and where the failure spoils temperature-sensitive materials, deterioration-of-stock cover responds. Business interruption can also engage if the outage halts production for a meaningful period.

Escape of water and flood. A burst pipe or a surface-water flood damages stock stored at low level, contaminates finished goods and puts machinery out of use. Buildings and contents respond to the damage, business interruption to the downtime, and the claim often exposes whether stock values and the indemnity period were set realistically.

Public or products liability. A visiting customer trips over trailing leads on the shop floor and is injured, or a component you fabricated fails in service and causes damage after it left your premises. Public liability responds to the first, products liability to the second — the reason both sections matter for a workshop that lets people in and sends work out.

The mistakes that cost you at claim

Underinsurance and the condition of average. This is the most common and most damaging error in workshop insurance. If the buildings, plant or stock sum insured is materially below the true reinstatement value, the average clause allows the insurer to reduce the settlement in the same proportion — so a building insured for half its rebuild cost can see even a partial-loss claim halved. Machinery and stock values set years ago, before inflation in materials and equipment, are a frequent trap. Our free underinsurance check at /underinsurance-check/ is designed to catch exactly this before a loss does.

The wrong indemnity period. Many workshops carry a twelve-month business-interruption indemnity period out of habit. After a serious fire, sourcing, installing and commissioning replacement machinery — and rebuilding a customer base — can take well beyond a year. If the indemnity period runs out before trading recovers, the shortfall falls on the business. Twenty-four or thirty-six months is often more realistic for a plant-dependent operation.

Breached conditions. Cover is routinely written subject to conditions — a hot-works permit and fire watch, an alarm kept in working order and set out of hours, minimum security to doors and windows, safe overnight storage of high-value items. If a condition is not met when the loss happens, the insurer may decline or reduce the claim. These are not paperwork; they are part of the contract you agreed to.

Undeclared activities and changes. Workshops evolve. A firm that started in light assembly takes on welding, adds a spray booth, begins storing customers' vehicles, or opens a second unit — and never tells the insurer. Under the Insurance Act 2015 duty of fair presentation, a material change that is not disclosed can prejudice the whole policy. Telling your broker when the business changes is what keeps the cover intact when you need it.

Compliance and risk considerations

Employers' liability. Under the Employers' Liability (Compulsory Insurance) Act 1969, if you employ anyone — including apprentices and labour-only staff — you must hold employers' liability cover, generally to at least £5m, and display or make available the certificate.

Health and safety duties. The Health and Safety at Work etc. Act 1974 places general duties on you toward employees and others affected by your work. Work equipment is governed by PUWER 1998, and lifting equipment such as hoists, cranes and vehicle lifts by LOLER 1998, which requires thorough examination at set intervals.

Pressure and process plant. Where you operate air compressors, receivers or steam plant, the Pressure Systems Safety Regulations 2000 (PSSR) require a written scheme of examination. Insurers frequently provide the engineering inspection that underpins these duties, and evidence of it supports your machinery cover.

Flammables and the environment. Where solvents, paints, dusts or LPG are present, DSEAR duties on dangerous substances and explosive atmospheres apply. If your process generates or stores waste at a level requiring a permit, the Environment Agency (England) or Natural Resources Wales (Wales) may need to be involved.

Fair presentation. The Insurance Act 2015 requires you to make a fair presentation of the risk. Disclosing your processes, values and any material changes accurately is both a legal duty and the practical foundation of a claim that pays.
