Before you sign, Spanish consumer rules require a business to give you clear information: who they are, what the work includes, the total price with taxes, how and when it will be carried out, the guarantee and how to complain. A good renovation quote adds detail: itemised tasks with units and quantities, materials included or excluded, exclusions in writing and a process for extras. VAT on home renovation may be charged at a reduced rate if specific conditions are met.
What must a business tell you before you sign?
Spanish consumer law sets out the information a business must provide before a consumer is bound by a contract. The Junta de Andalucía’s consumer service summarises it, and for a renovation the relevant points are:
- The main characteristics of the service — in other words, the scope of the works.
- The identity of the business: name, trading name, full address and telephone.
- The total price including taxes, or how it will be calculated if it cannot be fixed in advance.
- Payment arrangements and the date by which the work will be carried out.
- The legal guarantee and any commercial guarantee offered.
- Whether a right of withdrawal applies and how to exercise it.
- The complaints procedure.
This information must be provided free of charge and at least in Spanish. If you prefer to work in English, ask for both versions and agree which prevails.
What should a renovation quote contain?
A quote — presupuesto — is the backbone of the contract. A reliable one is itemised (por partidas): every task on its own line with a description, a unit of measurement and a quantity. For a renovation, check for:
- Strip-out and debris removal, including how waste leaves the building.
- Each service separately: plumbing, waste, electrics and who carries them out.
- Masonry, plastering and ceilings, measured by area.
- Floors and tiling, stating whether material is included and to what specification.
- Painting, fitting and the final clean.
- Exclusions: permits, technical projects, furniture, appliances, anything not covered.
- Guarantee terms and confirmation of liability insurance.
- A phased plan showing the order of works.
Our own quotes follow this format. How each line affects the total is explained on presupuestoreforma.eu; this guide is about structure, not prices.
Is a quote the same as a contract?
A signed, accepted quote can form the basis of the contract, but on anything larger than a small repair it is sensible to add a short written agreement or a set of conditions that covers what the quote does not. Typical points: the start date and any conditions for it, how materials you supply will be handled, access arrangements, what happens if the job is paused, how extras are agreed and how payment is staged against progress.
Stage payments linked to completed phases are fairer to both sides than large up-front sums. Be cautious of any builder who asks for most of the money before work starts. Pay by bank transfer to the business named on the invoice, and keep every invoice. Our post on red flags when hiring a builder in Spain covers warning signs in more detail.
How should extras and changes be handled?
Changes are normal. You see the room with the walls open and decide to move a doorway; strip-out reveals pipework in worse condition than expected. What causes disputes is not the change but the absence of a record.
A simple rule works: no extra work without a written description and price agreed beforehand. A message by email or WhatsApp with photos, a short description and the cost, and your written reply accepting it, is enough. At the end of the job, all agreed extras should appear as separate lines on the final invoice. That is how we work, and it is worth asking any builder you are considering how they handle it.
Can VAT on a home renovation be charged at a reduced rate?
Spanish VAT law allows a reduced rate for renovation and repair works on dwellings in certain circumstances. According to the Agencia Tributaria’s guidance, one key condition is that the materials supplied by the contractor must not exceed 40 per cent of the taxable base of the job; if they do, the whole job is taxed at the standard rate, and the invoice should reflect the materials cost or confirm the limit is met.
The same guidance states that where the dwelling is let rather than used privately by the owner, the standard rate applies. Other conditions also apply, relating to who receives the works and the age of the building (to be verified with a tax adviser for your situation). Ask any contractor how they will treat VAT on your job and why, before you sign. The VAT rate applied should be visible on the quote itself, not only on the final invoice, so that the total you agree is the total you pay.
What if something goes wrong after signing?
Start with a written complaint to the business describing the problem and what you want done. Most issues — a snag list item, a delayed delivery, a disagreement over an extra — are resolved at this stage when the paperwork is clear.
If not, Andalusia has a formal route. Under Decreto 82/2022, businesses that provide services to consumers in Andalusia must have official complaint forms (hojas de quejas y reclamaciones) available, and an electronic system is being introduced. A complaint filed on the official form goes to the business and can then be taken to the consumer authorities. Municipal consumer information offices (OMIC) can also advise. For our part, the guarantee terms and liability insurance details are in every quote. See also our turnkey renovation page for how responsibility is allocated on our jobs.
