How to Read a European Contractor's Quote (and Spot the Padding)
A quote is not a price - it is a description of how the contractor thinks, and where the risk sits. How to read one line by line, why the exclusions and provisional sums matter most, and how to compare three bids that look nothing alike.
A contractor's quote is the most information-dense document you get in a renovation, and the one people skim hardest. It is easy to read a quote as a single number and pick the smallest. But a quote is not a price - it is a description of how the contractor thinks: what they understood about your job, where they see the risk, and how much of the cost they have actually pinned down versus left floating. Read it properly and you catch the padding, the gaps, and the low bid that turns into the expensive one.
This guide is how to read a European quote line by line, what each part is really telling you, and how to compare three bids that look nothing alike. For the money side of the same conversation - deposits, staging and retention - see our guide to structuring contractor payments in Europe.
What a real quote contains
A professional quote is itemised. It breaks the job into stages or trades, shows what is included, and - just as importantly - what is not. A single round number with no breakdown is not a quote; it is an invitation to trust. The more detail a contractor commits to paper, the more they have thought the job through, and the less room there is for a surprise later.
| Element | What it tells you |
|---|---|
| Itemised scope | The contractor understood the job stage by stage, not as a lump guess. |
| Labour and materials split | Where the money goes, and whether the margins are normal. |
| Provisional / prime-cost sums | The parts still estimated - the most likely place for the price to move. |
| Exclusions | What you will pay for separately. This is where overruns hide. |
| Payment schedule | How exposure is staged, and whether it is front-loaded against you. |
| Validity date | How long the price holds before materials or availability reprice it. |
| Legal entity and VAT | Who you are actually contracting with, and whether tax is in or on top. |
Read the exclusions first
Counterintuitively, the most valuable lines in a quote are the ones listing what is not included. Waste removal, making good, scaffolding, permits, connection fees, VAT, materials you are expected to supply - each exclusion is a bill that lands on you later. A quote with a long, honest exclusions list is usually more trustworthy than one with none, because the one with none has simply not told you yet.
Provisional sums are placeholders, not prices
Where a contractor cannot yet know a cost - tiles you have not chosen, a foundation they cannot see until they dig - they insert a provisional or prime-cost sum: an allowance, not a fixed price. These are legitimate, but they are the joints where a quote flexes. Two bids can look far apart only because one used realistic allowances and the other optimistic ones. Ask what each provisional sum assumes, and price the ones that matter - kitchen units, bathroom ware - against real retail before you sign.
Is the margin normal?
A quote is allowed to carry margin - that is how a business survives. As a rough benchmark, expect something like 25 per cent or more on labour, 30 to 50 per cent on materials, and a 10 to 20 per cent uplift on provisional or prime-cost sums. A quote that shows its margin as an honest line item is a better sign than one that hides it: hidden margin does not mean no margin, it means you cannot see where it sits. Our breakdown of bathroom and kitchen pricing goes into these benchmarks in detail.
VAT, and the cash-discount trap
Check whether VAT is included or added on top. Several European countries apply a reduced VAT rate to the renovation of older homes - a real, legal saving that a proper invoice captures. What is not legal is the cash discount: the offer to knock off 'the VAT' for cash. Take it and you lose the reduced-rate invoice, any warranty tied to it, and the entire paper trail you would need if the job goes wrong. The discount is not a gift; it is the quiet removal of your protection.
Comparing three bids like for like
You cannot compare bids until they describe the same job. Line them up by scope: does each include the same works, the same allowances, the same exclusions? Normalise them - add the missing exclusions back into the cheap one - and the gap usually shrinks or reverses. The lowest number is very often the bid that understood the least, and it will find the rest of the cost through variations once you are committed and it is too late to walk.
The red flags, in one place
- A single round-number lump sum with no line-item breakdown.
- No exclusions listed at all - everything is 'included', until it isn't.
- Large provisional or prime-cost sums with no explanation of what they assume.
- VAT not shown, or a cash discount offered in place of a proper invoice.
- A payment schedule front-loaded so you pay well ahead of the work done.
- No validity date, no legal entity, and no VAT number on the document.
- A total far below the other bids, with no explanation you can verify.
Frequently asked questions
What should a contractor's quote include?+
An itemised scope broken into stages, a labour and materials split, any provisional or prime-cost sums clearly marked, a list of exclusions, a payment schedule, a validity date, and the contractor's registered legal entity and VAT number. A single lump sum with no breakdown is not a real quote - it is a number you are asked to trust.
Why is the cheapest quote often the most expensive?+
Because a low headline price is usually an under-scoped one. The cost that was left out - in thin provisional sums or missing exclusions - reappears as variations once you are committed and cannot easily change contractor. Normalise the bids to the same scope before comparing, and the cheapest often is not.
What is a provisional or prime-cost sum?+
An allowance for work whose cost cannot yet be fixed, such as tiles you have not chosen or a foundation not yet exposed. It is an estimate, not a price, so it is the part of a quote most likely to move. Ask what each one assumes and check the big ones against real retail before signing.
Should I accept a cash discount to avoid VAT?+
No. Paying cash to save the VAT loses you the proper invoice, any warranty tied to it, and the paper trail you would need in a dispute. In several countries the renovation of older homes qualifies for a reduced VAT rate anyway, which a legitimate invoice captures.
