How to Get a Fair Quote from a Spanish Builder - and Spot an Inflated One
A quote is not a price until you know what it includes
Getting a quote from a builder in Spain is easy. Getting three quotes for the same job that are actually comparing the same thing is considerably harder. One includes IVA, two do not. One includes materials, one is labour only, one is vague enough to cover either interpretation. One covers demolition and making good, the others assume you will sort that yourself.
This is not always deliberate, Spanish building quotes are not standardised and different builders structure them differently. But the lack of a common format is consistently exploited by those who want to look cheaper than they are. Here is how to make sure you are comparing the same thing across every quote you receive, and how to spot the ones that will cost you more in the end.
Always get a minimum of three quotes
Two quotes give you a comparison. Three quotes give you a market. With three written quotes in front of you, you have a genuine sense of what the job should cost, which quote is low and why, and whether the highest quote is genuinely premium or simply overpriced.
For jobs above €2,000, three quotes is the minimum sensible standard. For a full renovation or significant structural work, four or five quotes is not excessive. The time spent getting additional quotes is negligible against the scale of the decision you are making.
Do not use price alone to select between them. A quote that comes in 30 percent below the others deserves scrutiny, not celebration. The next section explains why.
What a proper written quote must include
Before you compare prices, check that every quote you have received contains the following. Any that do not should be sent back for clarification before you consider them further:
- Builder's full company name, registered address, and NIF - if these are missing, the quote is not from a registered business
- A detailed description of the work - specific enough that both parties would agree on what is and is not included. "Bathroom renovation" is not sufficient. "Supply and fit new shower enclosure, retile walls and floor, replace sanitaryware, replumb waste outlets" is.
- Materials specification - what brand or grade of materials, who supplies them, and what happens if specified materials are unavailable
- Labour costs broken out separately from materials - this is the single most important structural element of a quote. Without it you cannot assess where the money is going or query individual line items
- IVA clearly stated - either included in the total or shown as a separate line at the correct rate (21 percent for most building work, 10 percent for certain renovation work on primary residences, ask your builder which rate applies)
- Payment schedule - deposit amount, milestone payments, and final payment on completion
- Start date and estimated completion date
- What is explicitly not included - skips, demolition, making good, permits, professional fees
The reduced IVA rate - something most expats do not know about
Most building work in Spain attracts IVA at the standard rate of 21 percent. However, renovation work carried out on a property that is your primary residence (vivienda habitual) may qualify for a reduced IVA rate of 10 percent, provided the work meets certain conditions set out in Spanish tax law.
The conditions include that the property must have been completed for at least two years, that the work must be a genuine renovation rather than new construction, and that materials supplied by the contractor cannot exceed 40 percent of the total job value.
Not all builders will raise this automatically, some simply charge 21 percent across the board. It is worth asking your builder or a local gestor whether your project qualifies. On a €30,000 renovation, the difference between 10 and 21 percent IVA is €3,300, worth knowing about before you sign anything.
How to spot a quote that is too low
A quote that comes in significantly below the others is not automatically a bargain. There are four common reasons a quote comes in low on the Costa del Sol — and only one of them is good news:
- IVA is not included - add 10 or 21 percent and the quote may no longer look competitive
- Materials are not included - labour-only quotes are legitimate but must be clearly labelled as such. If it is not obvious, ask.
- Lower specification materials - the quote is for cheaper tiles, fittings, or components than the others. Not necessarily a problem if you know about it and accept it, a serious problem if you only find out mid-job.
- The builder intends to charge more later - quoting low to win the job and making up the margin through variations and extras once work has started. This is the most damaging scenario and the hardest to prove without a detailed written contract.
Ask directly about each of these points for any quote that looks notably cheaper. A legitimate builder will have a straightforward answer. Someone quoting low for the wrong reasons will get evasive.
How to spot a quote that is too high
Overpriced quotes are less common than underpriced ones on the Costa del Sol, but they happen, particularly with builders who target expats on the assumption that they do not know local rates and will not push back.
Signs a quote may be inflated:
- Labour rates significantly above the ranges in The SpainTrades Guide cost articles, €70 to €80 per hour for a general builder is reasonable, €120 to €150 per hour is not
- Materials marked up substantially above retail price, it is reasonable for a builder to add a margin on materials they source and supply, but 30 to 40 percent above retail is excessive
- Vague line items that are difficult to query, "miscellaneous works: €2,000" with no further explanation
- Permit costs that seem disproportionate, permit fees in Andalusia are set by the ayuntamiento and are not negotiable, so if permit costs look high, ask for a breakdown
Pushing back on a quote is not rude, it is sensible. Ask for a breakdown of any line item you cannot account for. A professional builder will explain it. If they cannot or will not, that tells you something.
The variation clause, the most important thing in any building contract
Even with a detailed written quote, building work in Spain sometimes throws up surprises. Concealed damp, outdated wiring behind walls, structural issues under floors, problems that were not visible when the quote was prepared and that genuinely cost more to fix.
A variation clause in your contract, agreed before work starts, sets out exactly how additional costs will be handled. It should state that any variation to the agreed price must be presented to you in writing and approved by you before the additional work proceeds. No surprises on the final bill, no "we found a problem so we just got on with it and here is the invoice."
Without a variation clause, every unforeseen problem becomes a negotiation you are having from a weak position, because the work is already done and you are being presented with a bill after the fact.
When the cheapest quote is the right choice
It does happen. Sometimes the lowest quote is from a builder who is simply more efficient, has lower overheads, sources materials better, or has a gap in their schedule that makes your job attractive to price competitively. The point is not to avoid the cheapest quote, it is to understand why it is cheapest before you accept it.
If the lowest quote is fully itemised, includes IVA, specifies materials clearly, comes from a registered and insured builder with good reviews, and the builder gives straight answers to straight questions, it may well be the right choice.
Before you ask for quotes
The easiest way to get fair quotes is to start with builders who are already vetted and reviewed. SpainTrades lists registered, insured builders and tradespeople across Málaga and the Costa del Sol, all reviewed by expat clients after real jobs. Starting with someone whose track record you can already check puts you in a much stronger position before a quote is even requested.
