Plenty of independent garages start the same way: a good technician gets tired of making money for someone else, finds a unit, and opens the doors. The technical side is the part they already know. The business side, from registering and VAT to insurance, waste and paperwork, is where new owners get caught out. This guide covers both: the official steps, each linked to the GOV.UK page it comes from, and the practical decisions on premises, suppliers, pricing, staff and systems that decide whether the garage is still busy in its third year. It is not legal or tax advice. For anything that depends on your own circumstances, talk to an accountant.
Decide what kind of garage you are building
Before the paperwork, be clear on what you will sell. General servicing and repairs, MOTs, tyres, diagnostics, air conditioning, a specialism in one make or in hybrids and EVs: each needs different equipment, space, skills and suppliers. You do not have to do everything from day one. A tight list of services you can do well, quickly and profitably is easier to market and easier to staff than a long list you do occasionally.
Think about who your customers will be, too. Retail drivers, local trade accounts and fleets want different things, and it is worth deciding early which you are chasing.
Choose a business structure and register
GOV.UK’s guide to setting up a business says most businesses register as a sole trader or limited company, and that the structure you choose can affect the way you pay tax and your legal responsibilities.
- Sole trader. GOV.UK describes this as the simplest business structure to set up and keep records for. You can start trading straight away without registering, but you must register for Self Assessment as a sole trader if you earn more than £1,000 in a tax year. Sole traders have unlimited liability, which GOV.UK explains means you are personally responsible for all of the debts of the business.
- Limited company. A limited company is legally separate from the people who own it, and owners are responsible for business debts only up to the value of their financial investment. You must register the company before you start trading. Directors have extra responsibilities, including keeping company and accounting records and filing accounts and tax returns. GOV.UK notes that directors can hire an accountant to help but remain legally responsible for the company’s records, accounts and performance.
GOV.UK also says you can move from one structure to another, and that it is usually easier to move from sole trader to limited company. Which suits you depends on your income, your risk and your plans, so this is the first conversation to have with an accountant.
VAT registration
GOV.UK’s VAT registration page says you must register if your total taxable turnover for the last 12 months goes over £90,000 (the VAT threshold), or if you expect your taxable turnover to go over £90,000 in the next 30 days. You can also choose to register if your turnover is below that, which GOV.UK calls voluntary registration.
Keep an eye on your rolling 12-month turnover from the start, not just your year-end figures, because the test looks back over the last 12 months at any point. Whether to register voluntarily, and how VAT affects your prices to retail customers, is another question for your accountant. Once you are registered, your invoices need to show more detail: the garage invoice guide sets out what HMRC requires.
Keep records from day one
Both structures have record-keeping duties from the first day of trading. If you are self-employed, GOV.UK says you need to keep records of all sales and income and all business expenses, plus VAT records if you are registered for VAT and PAYE records if you employ people. You must keep them for at least 5 years after the 31 January submission deadline of the relevant tax year. A limited company must keep accounting records including all money received and spent, and keep them for 6 years from the end of the last company financial year they relate to, or longer in some cases.
For a garage, that means every invoice, every supplier bill, every parts receipt and every payment. Set up a separate business bank account and a system that keeps job cards, invoices and payments together from the start. Untangling a year of mixed paperwork at tax time is much harder than doing it properly as you go.
Insurance
If you employ anyone, employers’ liability insurance is not optional. GOV.UK says you must get employers’ liability insurance as soon as you become an employer, to cover you for at least £5 million, from an authorised insurer. There are limited exceptions, for example if you only employ close family members. GOV.UK says you can be fined £2,500 every day you are not properly insured, and you must display your certificate where employees can access it.
Beyond that, GOV.UK’s sole trader and limited company guides tell you to check whether you need business insurance. A garage looks after other people’s cars, works with lifts and hot work, and keeps tools and stock on site, so talk to a specialist motor trade insurance broker about the cover your business needs before you take the first car in.
Premises and equipment
The unit you choose shapes everything that follows: how many bays you can run, whether you can fit a lift or an MOT bay, where customers park, and whether people can find you. Before you sign a lease, check access for recovery trucks, ceiling height for lifts, power supply, and whether the landlord and the local council are happy with vehicle repair on the site. GOV.UK’s sole trader guide notes that if you rent or buy a property, you may have to pay business rates, and that small businesses can apply for a discount.
Buy equipment for the work you will actually do in the first year, not the work you hope to do in five. A good two-post lift, a reliable diagnostic tool, a tyre machine and balancer if you will do tyres, and proper hand tools will carry most new garages. Leasing or financing bigger kit spreads the cost, but adds a monthly payment, so build it into your pricing.
Hazardous waste
Garages produce hazardous waste every day. GOV.UK’s hazardous waste guidance for England lists examples including chemicals such as brake fluid, batteries, and oils such as car oil, and says you must make sure hazardous waste produced or handled by your business causes no harm or damage.
As a business that produces or stores hazardous waste in England, GOV.UK says you must follow these steps as a producer or holder: classify your waste, separate and store hazardous waste safely, use authorised businesses to collect, recycle or dispose of it (checking that waste carriers are registered and waste sites have environmental permits), fill in your parts of the consignment note, and keep records (known as a register) for 3 years at the premises that produced or stored the waste. Scotland, Wales and Northern Ireland have their own rules, linked from the same GOV.UK page. Sort out a registered waste carrier before you open, not after the first drum of used oil is full.
Becoming an MOT testing station
MOTs bring cars through the door on a fixed cycle, which is why many independents want to test. GOV.UK’s guide to setting up an MOT test station says you need suitable premises and approved equipment for the vehicle classes you want to test, and an authorised examiner (AE), which can be an individual, partnership or company authorised by the Driver and Vehicle Standards Agency (DVSA). Before you can carry out MOT testing you also need an MOT business manager in charge of all MOT testing by your business, who must have taken an approved course, and an MOT tester approved for the vehicle classes you want to test.
To apply for authorised examiner status, you send form VT01 to DVSA, and GOV.UK says there is no fee for the application. AE status does not transfer with a business, so if you are buying an existing MOT station, you need to apply for AE status in your own right. Plan the MOT bay, the equipment and the people together, because you need all three before the first test.
Suppliers
Open trade accounts with more than one parts supplier before you need them. Factors compete on price, availability and delivery runs, and having a second account means a missing part is a phone call, not a lost day. Ask about delivery times to your postcode, returns, credit terms and how they handle warranty claims.
For tyres, set up accounts with a wholesaler or two so you can quote and fit without holding a big stock. If you use AutoChain, the GSF integration lets you pick parts in GSF TradeHub from a job’s work line, and they land back on that line with your prices, ready for you to place the order from the job. GroupTyre and Oak Tyres search shows your own trade prices and depot stock by tyre size while you add a tyre to a job, and you place the order with them as usual.
Pricing your work
Underpricing is the classic new-garage mistake: the diary fills up and the bank balance does not. Work out what each hour of labour actually costs you, including rent, rates, insurance, equipment, waste collection, software and your own wage, and price from there rather than from what the garage down the road charges. The guide to setting your garage labour rate walks through it step by step. Decide your parts margin at the same time, and write both down so everyone quotes the same way.
Your first hires
Your first hire changes the business. Before you take anyone on, GOV.UK’s employer steps include registering with HMRC as an employer and setting up PAYE, understanding your workplace pension duties, and getting employers’ liability insurance, as set out on the employers’ liability insurance page.
On the practical side, many owners find the first hire that frees them up is not another technician but someone on the front desk: answering the phone, booking work in, chasing approvals and taking payment. That gives you back hours on the tools. When you do hire technicians, be clear about what you expect in hours booked and invoiced, and check in on it regularly.
Systems: set them up before you are busy
The easiest time to set up proper systems is before the diary is full. A garage management system puts the booking diary, job cards, estimates, invoices, parts and customer reminders in one place, so nothing lives in someone’s head or on the back of an envelope. If you are moving off a paper diary or a spreadsheet, the switching guide covers how to do it without disrupting the workshop. If you are coming from another system, talk to us about bringing your data across when you book a demo.
Marketing from day one
A new garage has no reviews, no regulars and no word of mouth yet, so the first months are about being findable and making every customer count. Claim your Google Business Profile before you open, ask every early customer for a review, make it easy to book, and set up MOT reminders from the first car through the door. The guide on how to get more customers for your garage covers each of those in detail.
Growing to a second site
A second site works when the first runs without you in it every hour of the day. Before you expand, make sure the first site has a manager you trust, prices that make money, and systems that show you what is happening without you standing in the workshop. Then pick the new site for the same reasons as the first: access, visibility, space and a local customer base.
Running two sites on two sets of paper is where things fall apart. With AutoChain’s multi-site add-on, priced per site, you run more than one branch from one account, and the dashboard and analytics can be filtered by site so you can compare branches or focus on one.

How AutoChain supports a new or growing garage
AutoChain is garage management software built for independent UK garages from one bay upwards. Every job is a full record from the first booking to the final invoice: a registration lookup pulls the vehicle details and DVSA MOT history, jobs move through clear statuses on the jobs board, and the invoice is raised from the job with parts and labour carried over. That is the heart of garage job management software, and it builds a history on every car from day one. Invoices are VAT-ready, with credit notes, pay-online links through Stripe and live sync with Xero, QuickBooks Online or Sage Accounting. The dashboard shows revenue from completed work, predicted revenue from scheduled work and jobs by status, and technician analytics compare hours booked with hours invoiced.
The core plan is £69.99/mo + VAT with unlimited employees, no setup fee and a monthly rolling subscription you can cancel anytime. The first month is free on the core plan, with no card needed. See the pricing page for add-ons such as SMS, HaynesPro and multi-site.
