When viewing a property to buy, it is easy to focus on the layout, views and finishes. Its installations often receive attention later, although they influence both the renovation and its budget. The useful question is what information you still need to make a sound decision. A property viewing can identify questions; confirming the condition and capacity of the systems requires a professional review with an agreed scope.
Start with the documents that already exist
Ask the seller for available records of alterations, equipment and servicing. The Spanish Ministry of Consumer Affairs lists basic information buyers can request, including services, installations and the energy certificate. Organise what you receive by system and record which documents could not be found.
The energy certificate helps explain the property's calculated energy performance. As INEGA explains in its building certification guidance, it uses standardised occupancy conditions. It should therefore not be treated as a functional test of every appliance or an exact prediction of your bill. Likewise, having a manual does not demonstrate that equipment has been maintained correctly.
Consider your intended layout
Prepare a simple plan showing what you want to change: the kitchen, bathrooms, bedrooms and technical spaces. An installation may work in the current layout yet need substantial alteration when the points of use move. Ask about proposed pipework, drainage and duct routes, rather than looking only at the final position of an appliance.
For electrical systems, list the equipment you intend to add and where it will be used. A photograph of a closed consumer unit or visible labels can help the professional, but do not open protective covers or handle connections. The number of sockets and the appearance of switches do not establish the condition of concealed circuits. The review should distinguish visual observations from measurements that have actually been taken.
Separate private installations from shared building services
A ventilation outlet, drainage stack or outdoor-unit position may involve common parts of the building. Before assuming that a new kitchen or additional bathroom is feasible, identify what belongs to the individual property and which alterations need coordination with the owners' association and project professionals. An existing arrangement does not automatically authorise every alteration.
Request information about known incidents and planned building works. For a stain, establish when it appeared and whether its origin was investigated; a photograph cannot automatically identify a pipe leak, rainwater ingress or condensation. The initial aim is to define the investigation needed without turning a suspicion into a diagnosis.
Commission a review with specific questions
Instead of requesting a general check that everything is fine, agree what will be examined and what findings you will receive. This checklist helps prepare the visit:
- Address, approximate area, available plans and the intended renovation.
- Equipment you would like to retain, with photographs of accessible identification plates.
- Documented servicing or repairs and any known symptoms.
- Available access to consumer units, inspection openings and technical spaces.
- Requested checks and areas that cannot be inspected.
Ask for the conclusions to distinguish what was observed, what was measured and what remains unverified. If pipework is concealed or a system cannot be operated, the report should state that limitation. An installation review also does not replace structural, planning or legal advice about the purchase.
Turn the findings into renovation decisions
Use the results to create three groups: work needed before occupying the property, work best coordinated with the renovation and improvements that can wait. Give each proposal a scope and note its dependencies. You can then compare installation quotations using the same information, rather than hiding uncertainty within a single total.
If you are considering buying in Málaga, send us plans and photographs to discuss the installation review and renovation. Explain that you are still at the purchase stage and which decisions you need to resolve. This helps define the next step and plan a useful visit with specific objectives.
