How to Choose a Renovation Company on the Costa Blanca

To choose a renovation company on the Costa Blanca, start with the essentials: a properly registered business, current insurance and a budget broken down by chapters with clear payment terms. Then look at how it will actually run your project: who your point of contact is, how the trades are coordinated, how you will be kept informed and how well it knows local permits. Price matters, but it should be the last thing you weigh, not the first.

This article sets out what to look for, whichever company you end up working with.

Two ways to organise a renovation

Before assessing firms, it helps to be clear about the model you want.

• Hiring trades and builders yourself. You, or an architect you appoint, find and brief a builder and often separate firms for pools, glazing, joinery or air-conditioning. It can work well if you live locally, speak Spanish and have time to coordinate.
• A managed renovation. One company takes responsibility for the project as a whole: the brief and budget, design direction, the architect and permits where needed, the contractors and specialist trades, site monitoring, reporting and handover. You have one point of contact throughout.

For owners who live abroad, or simply do not want to coordinate several firms across a language barrier, the managed model of renovation project management removes most of that burden. The questions below apply to both, with a few extra ones for managed renovations.

Start with the basics: who they are, legally

A serious company will have no difficulty giving you its full legal details.

• Legal entity and CIF. A company has a CIF (now formally the NIF for companies); a self-employed builder (autónomo) trades under their personal NIF or NIE. Either can be legitimate, but you should know exactly who you are dealing with, and the name on the budget, contract and invoices should be consistent.
• Registered address and invoices with VAT. Proper invoices with IVA are what allow you to document the works, and in some cases apply the reduced 10% rate on qualifying home renovations. A tax adviser confirms whether it applies.
• Social security registration. Workers on site should be registered. It is a reasonable question to ask.
• A clear contractual set-up. Whatever the model, you should receive a written explanation of the contractual arrangements before any work starts, so you know who is responsible for what.

Insurance

Ask to see a current civil liability insurance policy (seguro de responsabilidad civil) and check the cover amount and expiry date. It protects you, your neighbours and the community against damage caused during the works. On larger projects, ask whether there is also insurance covering the works themselves while they are in progress, and whether the contractors working on site are insured.

Evidence of how they work

Photographs are easy to collect. What tells you more is how a company explains its process: how it surveys a property, how it builds a budget, how it schedules the works, what a progress report looks like and how it handles changes. Ask to see a sample report, a sample budget structure or a sample programme. If an established firm offers finished projects to visit, look at the details: tile joints, the junction between floor and wall, how doors close, the finish of the render, the sealant around the bathroom.

Be equally wary of claims you cannot check. A company that is open about what it is, and what it is not, is generally easier to work with.

How they budget

The budget tells you a great deal about how a company works. A good presupuesto is broken down by chapters, for example demolition, structure, masonry, roofing, plumbing, electrics, carpentry, tiling, painting and waste removal, with quantities, unit prices and specifications. It states what is excluded, how long the price is valid, and whether IVA is included.

If you are comparing firms, ask each to price the same document, ideally an architect’s execution project with a bill of quantities. That is the only way to compare like for like. In a managed renovation, look for a budget that also shows design, technical fees, permits and contingency clearly, and explains how costs are controlled as the project moves on. Our article on whether you need an architect in Spain explains when a project is required and what it contains.

One point of contact, and who is on site

Ask who will run your project day to day. Is there a named project manager and a site manager (encargado or jefe de obra)? How often is the site visited? Will the same team stay throughout? A company that is honest about its capacity, and tells you when it can realistically start, is generally more reliable than one that can start tomorrow.

For a villa renovation on the Costa Blanca, where a single project can involve builders, a pool specialist, glazing, joinery, installers and landscaping, it matters a great deal whether one person is accountable for all of it or whether you will be the one coordinating them.

Reporting and communication

Many international owners want to work in English, German, Dutch or French. Check that the person who will communicate with you during the works, not only at the first meeting, speaks your language well enough for technical conversations. Then agree how you will be kept informed:

• a regular written report with dated photographs and short videos;
• video calls at key stages;
• a shared folder for drawings, budgets and decisions;
• immediate notice of anything that affects cost, structure or timeline.

This is particularly important if you are renovating from abroad.

Local permit knowledge

Permits on the Costa Blanca are municipal. Each ayuntamiento applies regional planning law plus its own Plan General, so the same works can need a declaración responsable in one town and a licencia de obra mayor with a technical project in the next. Ask how the company establishes the right procedure for your property, who prepares and signs the technical documents where needed, and how permit timing is built into the programme. Coastal law, communities of owners and summer works restrictions are all worth raising.

Coordination of trades

Almost every renovation involves several trades, such as glazing, pools, specialist joinery or air-conditioning. That is normal. What matters is that someone clearly takes responsibility for coordinating them, that everyone working on site is insured, and that health and safety coordination is in place, which is required when more than one contractor or self-employed tradesperson works on site.

Payment terms

A reasonable payment schedule links payments to completed stages, not to dates. Expect a modest initial payment, then staged payments as milestones are reached, and a retention, often 5%, held until snagging is resolved. Be cautious about any request for a large share of the total before work starts.

Warranties under the LOE

Spain’s Building Act (LOE) sets liability periods for building defects: one year for finishing defects, three years for defects affecting habitability, and ten years for structural defects. Ask how aftercare is handled in practice: who you call, how quickly they respond, and whether the warranty terms are written into the contract.

A summary table

What to look for	Why it matters
Full legal name, CIF or NIF and registered address	You need to know exactly who you are dealing with
Written explanation of the contractual set-up	Makes responsibilities clear before work starts
Current civil liability insurance certificate	Covers damage to your property, neighbours and third parties
Budget broken down by chapters with specifications	Allows fair comparison and limits disputes over scope
One named point of contact and a site manager	Tells you who is accountable day to day
Regular reports with photos and video	Keeps you informed, especially from abroad
Language of day-to-day communication	Avoids misunderstandings on technical decisions
Knowledge of the local permit procedure	Avoids delays and works that cannot be legalised
How trades are coordinated	Clarifies responsibility on site
Payment schedule and retention	Keeps payments in step with progress
Written warranty and aftercare process	Protects you once the works are finished

Red flags

Some warning signs are worth taking seriously:

• requests for cash payments or invoices without IVA;
• a single-line budget with no breakdown;
• pressure to sign quickly or to pay a large advance;
• reluctance to show insurance or explain the contractual set-up;
• advice to skip permits because “nobody checks”;
• a price far below the others with no clear explanation;
• no written contract, or a contract with no timeline or payment milestones;
• claims of experience, awards or reviews that cannot be verified.

Any one of these is a reason to ask more questions. Several together are a reason to walk away. Our article on common renovation mistakes in Spain covers what tends to go wrong when they are ignored.

In short

• Decide first whether you want to coordinate trades yourself or have one company manage the whole renovation.
• Confirm legal identity, insurance and a written contractual set-up before anything else.
• Ask for a chaptered budget against a clear specification, ideally an architect’s bill of quantities.
• Look for one point of contact, regular reporting and genuine local permit knowledge.
• Agree milestone payments with a retention, and a written warranty in line with the LOE.
• Treat cash requests, vague budgets and advice to skip permits as serious red flags.
