Buying a Commercial Unit to Convert into a Home in Spain

Ground-floor commercial premises in Spain are often priced well below flats of a similar size, and that gap is what draws investors browsing from the United Kingdom. The idea of turning a shuttered shop or old office into a home sounds straightforward, but it depends entirely on a change-of-use licence that the town hall may or may not grant.

Before transferring any funds from a UK account, it is worth understanding what the conversion actually requires: planning permission, a technical project signed by an architect, and proof that the space meets residential habitability rules. None of this is guaranteed to be quick, and the extra cost sits on top of the renovation budget itself.

Spanish town halls look at specific, technical questions before granting a change of use: minimum ceiling height, natural light and ventilation in habitable rooms, access to the building, and whether the premises can be separated from any shared commercial entrance. A unit that once sold hardware or ran as a bar may fail on light alone, however attractive the price.

This is why Sókerim always arranges a technical check with an architect before a client signs anything, as part of the standard property checks in our buying service. For a managed investment, our own renovation team reviews the same points before we recommend a purchase to a client, not after.

There is no single, fixed timeframe for a change-of-use licence; it depends on the municipality, the building's history, and how complete the technical file is when submitted. Some town halls process straightforward cases in a few months, others take considerably longer, especially where the building has mixed commercial and residential use or sits in a protected zone.

Because this adds time before any renovation work can legally begin, buyers planning a managed investment with Sókerim should treat the licence stage as a separate phase, not an extension of the refurbishment schedule agreed on later.

The architect's project, municipal fees for the licence application, and any structural work needed to meet habitability rules are separate from the renovation budget itself. Across the 19 homes our group has bought, renovated and resold for investor projects since 2022, the median renovation budget has been 22% of the purchase price — but that figure covers refurbishment, not a change-of-use process, which is its own line item when a commercial unit is involved.

Purchase costs follow the usual pattern for resale property in Spain: transfer tax set by the region, notary and land registry fees, and a gestoría to handle paperwork. A lawyer is optional but usual for buyers based in the United Kingdom, partly because of the added complexity a change-of-use case brings.

Whether you buy directly or through our managed investment service, the property is always registered in your own name — Sókerim never pools investors' funds and this is not a collective scheme. From the United Kingdom, a lender assessing your mortgage application will typically ask for recent payslips or a P60, your last filed Self Assessment return, bank statements from the last few months, and evidence of any existing loans or mortgage commitments; the Spanish notary, for their part, will ask for your valid passport and your NIE at signing.

As the United Kingdom is no longer an EU member state, British citizens can stay in Spain for up to 90 days in any 180-day period without a visa; longer stays require a residence permit, and the Spanish Golden Visa for property investors ended on 3 April 2025 and is no longer available as a route to residence.

Once the change of use is registered and the renovation complete, the options are the same as for any home: live in it, rent it out long-term, or apply for a tourist licence where the region and building allow one — many do not, so this should be confirmed before counting on short-let income. Spain and the United Kingdom have a double taxation agreement, and a local tax adviser should confirm exactly how rental income or any future gain must be declared, both to the Spanish tax office through the annual Modelo 210 and to HMRC.

If you later sell as a non-resident, the buyer withholds 3% of the price on account of your Spanish tax, and a separate municipal capital-gains tax on the land value, called plusvalía, also applies. Because transfers run in pounds sterling, it is worth watching exchange-rate movements and conversion costs at both ends of the operation.

Spain is a relatively short flight away from most UK airports, making regular visits to a Spanish property straightforward for owners based in Britain. Many British buyers are drawn to Spain for its climate, coastal lifestyle and established expatriate communities. One practical point to bear in mind is that Spanish inheritance law differs from UK rules, so it is worth taking specific advice on how it may affect the property and one's estate. Currency movements between sterling and the euro can also affect the overall cost of purchase and ongoing expenses.

Spain and the United Kingdom have a double taxation agreement in place, and a local tax adviser should confirm how rental income or gains from Spanish property must be declared and reported to HMRC.

As the United Kingdom is no longer an EU member state, British citizens may stay in Spain for up to 90 days in any 180-day period without a visa, and must apply for a visa or residence permit for longer stays.

Since the United Kingdom uses the pound sterling (GBP) rather than the euro, buyers should factor in exchange-rate movements and currency conversion costs when paying for a property or transferring funds to Spain.
