Motor Trade Insurance for Small Garages & Repair Shops: What You Actually Need
What Motor Trade Insurance Actually Covers
Motor trade insurance is a specific business policy designed for people who work on customer vehicles. You need it if cars regularly come into your possession for service, repair, modification, or testing—not because your regular car insurance won’t do, but because the law requires it and standard policies explicitly exclude business use on customers’ cars.
The policy covers third-party liability when you’re working on someone else’s car, damage or loss while vehicles are in your care, and your right to drive those cars on the road for demos or test drives. It’s different from standard business liability because it focuses on the vehicles themselves.
Cost Breakdown for 2026
Premiums vary wildly depending on your operation size:
- Solo traders doing valeting or basic work: £700–£1,200 per year
- Small repair workshop with 2–3 staff: £1,800–£2,800 per year
- Multi-bay garage or dealer with stock: £3,000–£6,000+ per year
These are approximate—actual prices depend on your turnover, how many vehicles you handle at once, the types of work you do, and your claims history. Premiums have risen 10–15% since 2024, mainly because repair costs have climbed alongside parts shortages and complex vehicle electronics.
Combined vs. Standalone Policies
You can buy road risk cover alone (the bare minimum), but most small garages choose combined motor trade insurance. This bundles road risks with:
- Business premises cover (fire, theft, weather damage)
- Tools and equipment insurance
- Stock and vehicle cover
- Public liability (covers injury to customers or passersby)
- Employers’ liability (required by law if you have staff)
A single combined policy is usually cheaper than buying pieces separately and means fewer gaps in coverage.
Third Party vs. Comprehensive Road Risk
When insuring the cars themselves, you’ll pick a coverage level:
Third Party Only (TPO): Covers damage you cause to someone else’s property and injury to third parties. Legal minimum but doesn’t protect the customer’s car if you damage it while working. Cheapest option.
Third Party Fire & Theft (TPFT): Same as TPO plus covers theft and fire damage to customer vehicles in your care. Middle ground.
Comprehensive: Covers accidental damage, theft, fire, and vandalism. Most protection but most expensive. Many garages don’t use this because customers are usually responsible for their own vehicle damage.
For a repair shop, TPFT is the practical choice—it covers the risks you actually face.
What to Ask When Getting Quotes
Insurance is individual, so compare quotes from brokers rather than assuming the cheapest will work. When you ring around, have ready:
- Your annual turnover and what you actually do (repairs, mods, valeting, diagnostics)
- How many vehicles you typically have on site
- Number of employees and their roles
- Any claims in the past 3–5 years
- Whether you do bodywork, electrical, or just mechanical
Specialist brokers like Nash Warren, AJG, Howden, and Coversure each have relationships with different underwriters—one might offer better rates for a certain type of work. Don’t just phone one company and accept the first quote.
Reducing Your Premium
A few practical levers:
- Start with a higher excess. Raising your excess from £250 to £500 or £750 can drop the premium by 10–20% if you’re confident you won’t claim for minor damage.
- Limit the number of vehicles in care at once. If your policy says you never have more than 5 cars on site, that’s cheaper than a limit of 20.
- Specify the work you do. A garage that only does MOTs and basic servicing is less risk than one doing engine rebuilds and tuning.
- Pay annually if you can. Monthly payments add interest and admin fees.
Don’t Skimp on Public Liability
This is the one area where cutting corners backfires. Public liability covers you if a customer is injured in your workspace or if your work causes damage later. A single incident—someone slipping and hitting their head, or a repair failure causing an accident weeks later—can cost thousands. Most policies offer £5–£10 million cover for a small additional cost. Take it.
