Mechanics insurance protects your business against damage to customer vehicles, injury claims, tool theft and business interruption. Whether you’re a mobile mechanic working from a van or running a fixed garage with employees, the right cover is essential.
Prices vary widely depending on your business structure, location, staff numbers and the type of work you do. This guide explains typical costs and what affects your premium.
Average Mechanic Insurance Costs
| Type of mechanic | Typical annual cost |
|---|---|
| Mobile mechanic (sole trader) | £1,200 – £2,000 |
| Self-employed mechanic (small garage) | £1,500 – £2,500 |
| Garage with 1-2 staff | £2,000 – £3,500 |
| Larger workshop with multiple staff | £3,000 – £5,000+ |
These are estimates. Your actual premium depends on cover levels, claims history, location and business specifics.
What Does Mechanics Insurance Cover?
A full motor trade policy for mechanics typically includes:
- Road risks insurance: covers you and any named drivers when driving customer vehicles for test drives, collections and deliveries. Available as third party only, third party fire and theft, or comprehensive.
- Public liability: protects against claims if a customer or member of the public is injured or their property is damaged. Cover of £2-5 million is standard.
- Employers’ liability: legally required if you have staff. Provides £10 million cover for employee injury or illness claims.
- Tools and equipment: covers theft or damage to your tools, whether stored at your garage, in your van or at a customer’s location.
- Premises and contents: insures your workshop building (if you own it) and fixtures, stock and equipment inside.
- Business interruption: replaces lost income if you can’t trade after an insured event like a fire or flood.

What Affects the Cost of Mechanic Insurance?
Business Type and Location
Mobile mechanics often pay less because they have no premises to insure, but road risks cover is essential. Fixed garages need buildings insurance, contents cover and often higher public liability limits.
Postcodes with higher vehicle crime or claims history increase premiums. Operating in central London or Birmingham typically costs more than rural areas.
Driver Ages and Licence History
Any driver under 25, or anyone with motoring convictions in the past five years, increases premiums significantly. Insurers assess every person who will drive customer vehicles.
A clean driving licence with five years’ no claims discount can reduce your road risks premium substantially.
Road Risks Cover Level
Comprehensive road risks cover costs more than third party only, but it protects you if a customer’s car is damaged during a test drive or collection. Most garages choose comprehensive because the risk of being personally liable for an expensive repair is too high.
Third party only might save £200-300 annually, but you’re exposed if you damage a £40,000 vehicle.
Value of Tools and Equipment
Diagnostics equipment, ramps, trolley jacks and power tools add up quickly. A mobile mechanic with £5,000 of tools pays less than a garage with £30,000 in equipment and machinery.
Keep an up-to-date inventory with receipts. Under-insuring your tools means you won’t be fully covered if they’re stolen.
Type of Work
Standard servicing and repairs are lower risk. Performance tuning, engine rebuilds, classic car work and MOT testing typically increase premiums because the vehicles are more valuable or the work carries higher liability.
Specialist work on high-value or modified vehicles can add 20-40% to your premium.
Number of Employees
Each additional staff member increases your employers’ liability exposure and overall risk profile. You must have employers’ liability insurance by law if you employ anyone, even part-time.
Adding your first employee typically increases premiums by £300-600 annually.
Claims History
A clean record keeps costs down. Previous claims, especially for damage to customer vehicles or injury, push premiums up for several years.
Even a settled claim stays on your record for five years and can increase renewal premiums by 30-50%.
Mobile Mechanic Insurance Cost
Mobile mechanics working as sole traders typically pay £1,200 to £2,000 per year. This usually covers:
- Road risks (third party or comprehensive)
- Public liability (£2 million minimum)
- Tools in transit (up to an agreed limit, often £5,000-10,000)
- Personal accident cover
You won’t need employers’ liability if you work alone, and premises cover isn’t required if you operate from home without storing significant equipment or stock.
If you’re working from home, check whether you need specific cover in our guide on home-based motor traders.
Self-Employed Mechanic Insurance Cost
Self-employed mechanics operating from a small rented garage or unit can expect to pay £1,500 to £2,500 annually. This includes:
- Road risks cover
- Public liability (£2-5 million)
- Contents insurance for tools and equipment
- Limited premises cover (if you have a lease)
If you take on an apprentice or part-time assistant, you’ll need to add employers’ liability, which increases the premium.
Garage and Repair Workshop Insurance Cost
Established garages with staff typically pay £2,000 to £5,000+ per year. Larger premiums reflect:
- Multiple drivers on the road risks policy
- Higher public liability limits (often £5 million)
- Employers’ liability for all staff
- Full premises and contents cover
- Business interruption insurance
Workshops offering MOT testing, bodywork or performance tuning often sit at the higher end of this range.
Public Liability Insurance for Mechanics
Public liability covers you if a customer or visitor is injured at your garage, or if you damage their property. Minimum cover of £2 million is standard, but many mechanics opt for £5 million.
Typical claims include:
- Customer slips on oil in your workshop
- Tool falls and damages a customer’s vehicle
- Faulty repair causes an accident
Public liability usually costs £200-400 as a standalone policy, but it’s cheaper when bundled into a motor trade package. You can read more about whether public liability is necessary in our article on public liability insurance for motor traders.
Tool Insurance for Mechanics
Tool cover protects your equipment against theft, fire and accidental damage. Most policies cover tools:
- Stored at your garage or workshop
- In your van overnight
- At a customer’s location
- In transit between jobs
Mobile mechanics should check whether overnight van storage is covered. Some insurers require tools to be removed from the van overnight, or apply a lower limit for tools left in an unattended vehicle.
Typical limits range from £5,000 for a mobile mechanic to £30,000+ for a fully equipped garage.
How to Get Cheaper Mechanic Insurance
Improve security
Fit alarms, CCTV, security shutters and a tracked key safe. Insurers reward strong premises security with lower premiums. Storing tools in a locked room within your garage can also reduce costs.
Limit road risks drivers
Only add experienced drivers with clean licences. Removing young or inexperienced drivers from your policy can save hundreds of pounds annually.
Increase your excess
A higher voluntary excess reduces your premium, but make sure you can afford it if you claim. Increasing your excess from £250 to £500 might save £100-150 per year.
Pay annually
Monthly instalments include interest. Paying upfront saves 10-15% on average.
Accurate tool valuations
Don’t over-insure, but make sure your total is realistic. Keep receipts and photographs in case you need to claim.
Use a specialist broker
Motor trade insurers understand your risks better than high-street providers and often offer better terms. They also have access to specialist underwriters who cover mobile mechanics and small garages.
Why You Need Specialist Mechanic Insurance
Standard business insurance and personal car policies don’t cover you when handling customer vehicles. If you damage a customer’s car during a test drive without road risks cover, you’re personally liable for the repair bill.
Public liability and employers’ liability protect your business and personal assets if something goes wrong. Even a minor injury claim can run into tens of thousands of pounds.
