Buying a New Build in Spain: What UK Buyers Need to Know (2026)
A British couple I spoke to recently had been watching the Costa del Sol market for two years. When they finally decided to act, they went off-plan on a new development in Estepona. Six months later, they had a snagging list of 43 items, a disputed completion date, and a developer asking for stage payments they hadn’t budgeted for.
None of it was a disaster. But all of it was avoidable with the right preparation.
New builds on the Costa del Sol are selling fast. Developers like Taylor Wimpey España, Neinor Homes, Metrovacesa, and dozens of boutique local firms are delivering thousands of new units a year between Estepona and Sotogrande. For British buyers, the combination of modern finishes, energy efficiency ratings, and developer warranties is genuinely compelling.
But the buying process for a new build differs from a resale in almost every important way. Here is what you need to know before you sign anything.
The Tax Picture Is Completely Different
This is the number one thing that catches buyers off guard.
On a resale property in Andalucía, you pay ITP (Impuesto de Transmisiones Patrimoniales), the transfer tax, currently set at a sliding scale of 7% to 10% depending on price. On a new build, you pay two different taxes instead:
- IVA (VAT): 10% on residential new builds. Charged by the developer and non-negotiable.
- AJD (Actos Jurídicos Documentados): the stamp duty equivalent. In Andalucía this is currently 1.2% of the purchase price.
So on a €400,000 new build, your tax bill looks like this:
| Tax | Rate | Amount |
|---|---|---|
| IVA | 10% | €40,000 |
| AJD | 1.2% | €4,800 |
| Total | €44,800 |
Compare that to the ITP on a €400,000 resale in Andalucía, which sits at around 8% at that price band: €32,000.
New builds cost more in tax. Factor this in when you are building your budget. On top of IVA and AJD, add notary fees, land registry fees, and your lawyer’s fee. Budget an additional 1 to 1.5% for those. For a full worked example of all the buying costs on a Costa del Sol property, see our complete breakdown here.
Off-Plan: What You Are Actually Buying
Most new builds on the Costa del Sol are sold off-plan, meaning you buy before the property is finished, sometimes before construction has started. This is entirely normal. But it comes with a specific set of risks you need to understand.
When you buy off-plan, you sign a private purchase contract (contrato de compraventa) with the developer. At that point, you typically pay:
- A reservation fee: usually €5,000 to €10,000
- A stage payment at contract exchange: commonly 20 to 30% of the purchase price
- Further stage payments during construction (varies by developer)
- The balance on completion, when keys are handed over and any mortgage is drawn down
The critical protection you need: Under Spanish law, specifically Ley 57/1968 (now incorporated into the Building Act), any stage payments made before completion must be held in a ring-fenced bank account and backed by a bank guarantee (aval bancario). If the developer fails to complete or goes insolvent, you can recover every euro you paid.
In practice: always verify the bank guarantee exists before you transfer any stage payment. Your lawyer should obtain this documentation for you. Do not skip this step because the developer seems large or reputable. There are real cases where buyers lost deposits on developments that stalled without proper guarantees in place.
The Payment Structure and Mortgage Timing
Mortgages on off-plan properties work differently from resale mortgages, and this catches British buyers out more than almost anything else.
On a resale, you get your mortgage approved and complete on the same day. On an off-plan, completion may be 18 to 36 months away. Most Spanish lenders will issue a formal mortgage offer only when the property is close to completion, which means:
- You make stage payments from your own funds during construction.
- You apply for a mortgage in the months before the expected completion date.
- You draw the mortgage down on completion day.
The implication: you need to have the stage payment cash available upfront, before your mortgage is in place. Budget for this carefully.
You also need your NIE (the Spanish tax identification number for foreigners) sorted well before you need it. Banks will not open accounts without one, and developers will not let you sign without one. Here is our step-by-step guide to getting your NIE from the UK.
As a British buyer post-Brexit, expect a maximum LTV of around 60 to 70% on a Spanish non-resident mortgage. That means 30 to 40% down from your own funds, plus taxes and fees on top.
Developer Guarantees: What the Law Says
All new builds in Spain come with three legally mandated warranty periods. These are minimums set by law, not optional extras:
- 1 year for finishing defects: cosmetic issues, paintwork, tiles, fixtures, joinery
- 3 years for habitability defects: waterproofing failures, insulation, plumbing leaks
- 10 years for structural defects: foundations, load-bearing walls, the structure itself
These protections exist under the Ley de Ordenación de la Edificación (LOE). The developer cannot contract out of them, and they transfer to subsequent owners if you sell.
What this means in practice: if a water pipe buried in a wall fails during year two, the developer pays to fix it. If the roof leaks in year eight, same story. Keep all your completion certificates, contracts, and handover documentation in one place. You will need them if you ever have to make a claim.
Snagging: Your Most Important Job at Handover
Snagging is the process of inspecting your property at the point of handover and formally recording every defect before you accept the keys. It is the single most valuable thing you do on completion day, and it is your legal right under Spanish law.
You sign an acta de entrega (handover document) and anything listed as defective at that moment goes onto the developer’s repair obligation. Once you sign without reservation, it gets harder to pursue minor items.
What to do on handover day:
- Hire an independent snagging inspector. They charge around €200 to €400 for a thorough apartment inspection. Given what is at stake, this is well-spent money.
- Do not sign the handover document until the snagging inspection is complete, or until you have explicitly reserved the right to add items within a short agreed window.
- Check everything: every socket, tap, door hinge, floor tile, window seal, extractor fan, and kitchen appliance. Compare the kitchen and bathroom finishes against the memoria de calidades (materials specification) you were given at sale.
- Get all identified defects in writing, signed by a developer representative.
A snagging list of 20 to 50 minor items on a Costa del Sol new build is completely normal. Serious structural problems at handover are rare. Cosmetic and finishing defects are not.
Choosing a Developer You Can Trust
The Costa del Sol has some excellent developers and some that fall well short. A few checks worth doing before you commit:
Track record. Has the developer completed projects locally before? Ask to see finished developments in the area. If possible, speak to buyers who have already moved in.
Financial backing. Is the developer using a reputable Spanish lender for construction finance? Most credible developers will confirm this. It is a reasonable signal of financial stability.
Materials specification. Get the memoria de calidades in writing at point of sale and keep a copy. If the brochure specifies a particular tile brand or kitchen supplier and you receive something cheaper, you have a documented basis for complaint.
Delivery history. Construction delays on the Costa del Sol are common. Ask about the developer’s track record on delivery dates and build a buffer into your own timeline. Most buyers plan for at least a three to six month delay on the original quoted completion date.

What the Energy Efficiency Rules Mean for You
All new residential builds in Spain must achieve a minimum energy efficiency rating of C (on the A to G scale). In practice, most quality Costa del Sol developers are targeting A or B ratings, which has real financial implications.
Lower energy bills are the obvious benefit. But the energy rating also affects future resale value. As EU regulations around minimum energy standards for property tighten over the coming years, a well-rated new build will be significantly easier to sell than an older property with a poor rating.
If you are comparing a new build to a resale, factor in the likely cost of any energy improvements you would need on an older property. On some older apartments, bringing the insulation, glazing, and systems up to modern standards can add €10,000 to €30,000 to your real acquisition cost.
Is a New Build the Right Choice for You?
A new build makes sense if you want:
- Modern finishes with no renovation cost or risk
- A strong energy efficiency rating and lower running costs
- Legal warranty protection for the first ten years
- The ability to customise finishes at point of sale (on pre-launch purchases)
- A property in a managed community with shared facilities
A resale may suit you better if you want:
- An established community with mature gardens and a known track record
- A faster transaction, with no 18 to 36 month construction wait
- A lower overall tax bill (ITP tends to be cheaper than IVA plus AJD)
- A property in a location where no new developments exist, particularly in more established parts of Marbella or Sotogrande
Neither is universally the right answer. It depends on your priorities, your timeline, and what your budget allows once all the taxes and costs are factored in.
