Parts Markup: What Percentage Should a Garage Charge in the UK?
How independent garages price parts, typical markup ranges, when a matrix beats a flat percentage, and how to stay profitable without customers feeling stung.
2026-09-25 · 7 min read
Parts are the quiet half of garage profit. Labour gets all the attention, but the markup on parts often decides whether a job was worth doing — and it is the number customers most often challenge.
Independent garages commonly apply somewhere between 20% and 50% markup on parts, with the percentage usually falling as the part gets more expensive. There is no rule, but there is a logic, and this guide lays it out.
It also covers the conversation every garage knows: 'but I can get it cheaper online.'

Typical parts markup ranges in the UK
Markups vary by garage, supplier terms and part type, but the pattern is consistent: cheap parts carry a high percentage, expensive parts a lower one.
| Part cost (trade) | Typical markup | Why |
|---|---|---|
| Under £10 | 50 – 100%+ | Handling a £3 filter takes the same time as a £300 part |
| £10 – £50 | 40 – 60% | Covers ordering, stocking and warranty risk |
| £50 – £200 | 25 – 40% | Percentage falls as cash value rises |
| £200+ | 15 – 30% | Large parts are priced to stay competitive |
- These are ranges, not rules — your supplier discounts and local competition move them.
- The markup is not pure profit: it funds ordering time, returns, warranty handling and the shelf space for stock.
Why a flat percentage loses money
A flat 30% sounds simple until you price a £4 bulb (earning £1.20 for the hassle of ordering it) or a £900 gearbox (adding £270 a customer will definitely question).
That is why many garages use matrix pricing: a sliding scale where the percentage falls as cost rises. You set the bands once, then every part prices itself consistently — no gut-feel discounting on big jobs, no embarrassing £1.20 lines.
Markup versus margin: get the words right
Markup is what you add to cost: buy at £50, sell at £65, markup is 30%. Margin is profit as a share of the selling price: the same £15 on £65 is a 23% margin.
Mixing the two up is how garages think they are making 30% and bank 23%. When you compare supplier terms or set targets, decide which word you are using and stick to it.
'I can get it cheaper online': the answer that works
Customers can often find the part cheaper. What they cannot buy online is the part being the right one, here today, fitted correctly, and warranted with the job.
Most garages handle it with facts: the price includes sourcing the correct part for their registration, the supplier warranty handled by you, and no comebacks if the internet special turns out to be the wrong side or the wrong spec. Garages that fit customer-supplied parts usually exclude warranty on the whole job — and say so on the estimate, not after.
Keeping parts pricing honest and profitable
- Review supplier prices monthly — trade prices drift up silently while your sell prices stand still.
- Show parts as their own invoice lines: transparency is what makes markup defensible.
- Record parts on the job sheet as they are used, so nothing walks off the shelf unbilled.
- Decide your bands once and apply them to everyone — consistency is what customers call fair.
Garage management software FAQ
What is a typical parts markup for a UK garage?
Commonly between 20% and 50%, with cheaper parts carrying the highest percentages and expensive parts the lowest. Small consumables can be marked up 50–100% because the handling cost dominates, while parts over £200 often sit at 15–30% to stay competitive.
What is the difference between markup and margin?
Markup is the percentage added to the cost price; margin is profit as a percentage of the selling price. Buy at £50 and sell at £65 and the markup is 30% but the margin is 23%. Confusing the two leads garages to overestimate their profit.
Should garages fit customer-supplied parts?
That is a policy decision, but most garages that do it exclude warranty on the job and say so in writing on the estimate. You cannot warrant a part you did not source, and the labour risk stays with you either way — which is why many garages decline customer parts entirely.
What is matrix pricing for parts?
A sliding markup scale where the percentage falls as the part's cost rises — for example 60% under £10, 40% up to £50, 25% up to £200, 15% above. It stops cheap parts being unprofitable and expensive parts being uncompetitive, and it keeps pricing consistent across the team.
Do garages charge VAT on parts?
Yes — if the garage is VAT registered, parts are standard-rated at 20%, applied to the selling price including your markup. The MOT test fee is the well-known exception: it sits outside the scope of VAT.
Bottom line
Set your bands once, review supplier prices monthly, and show parts clearly on the invoice — then markup stops being an argument and starts being a system.
The garages that lose money on parts rarely price too low; they price inconsistently.
