Ask what a normal viewing can and cannot prove
With permission, run taps, flush toilets, switch ordinary lights on and turn heating controls briefly. This may reveal poor flow, slow drainage or an obvious fault. It cannot show the condition of concealed pipework, test electrical safety or predict how long a boiler will last.
A building survey normally comments on visible age and condition and does not include specialist tests. Read the surveyor’s scope before assuming services are covered. If replacement would affect your decision or budget, arrange the relevant inspection while you can still act on the result.
Read boiler records with a practical eye
Find the boiler and ask its age, fuel, service history and whether any warranty can be transferred. A recent service is helpful, though it is not a promise of future life. Check where the flue ends and whether the heating reaches extensions, loft rooms and bathrooms.
Ask the seller to demonstrate the controller rather than accepting that it is “somewhere in the drawer”. Look at the hot-water arrangement and tank if there is one. For heat pumps or less familiar systems, find out who maintains them, how controls work and whether you can obtain local servicing.
Electrical clues that justify further questions
Look at the consumer unit without removing its cover. Mixed styles of sockets, old switches, many extension leads or untidy additions may indicate work from different periods. Modern-looking equipment does not confirm that the hidden circuits were renewed at the same time.
Ask for recent electrical installation or inspection records and certificates for relevant work. Your conveyancer can request documents, but an electrician judges the installation. If the house is old, heavily altered or relies on electric heating, an Electrical Installation Condition Report may be sensible before exchange. Agree who will pay and make sure the electrician can access the areas that matter.
Water pressure and drainage deserve time
Try more than one tap and ask whether flow changes when another outlet runs. Look beneath sinks for swelling, stains and improvised connections. Around showers and baths, check seals, floors and the ceiling below. A small recurring leak can damage boards and joists without producing a dramatic mark.
Watch whether basins and toilets clear normally. Outside, note inspection covers, gullies and large trees near drain routes. A drainage survey is not necessary for every purchase, but recurring blockages, old pipes, subsidence concerns or building over a drain give it a clear purpose.
Know where supplies enter and how they are stopped
Find the internal water stop tap, gas meter, electricity meter and any oil or LPG storage. Ask whether the stop tap moves freely, but do not force it. In a flat, establish which meters belong to the property and whether any supplies or heating systems are communal.
Private water supplies, septic tanks and shared drainage bring additional maintenance and legal questions. Your conveyancer needs the arrangements in writing, while a suitable specialist may need to inspect physical condition. Check access rights and emptying records instead of assuming a system works simply because the taps run.
Budget from evidence, not the oldest date you hear
An older boiler or consumer unit does not automatically need immediate replacement. Condition, safety, parts availability and suitability matter. Ask a specialist to separate essential work from improvements and future planning. Obtain written estimates for large items, including making good around new pipes or wiring.
Use the findings in the overall purchase decision. Rewiring before decorating is very different from doing it after moving furniture in. If the seller offers to arrange repairs, agree the exact work and evidence required. Sometimes a price adjustment and your own contractor provide clearer control, but discuss the contractual position with your conveyancer before making an agreement.
Ask which manuals, keys, thermostat instructions and service contacts will be left at completion. Photograph settings before changing them. It can take time to understand an unfamiliar heating system in the first cold week. Check whether any smart controls will be reset and transferred to a new account. Include that setup and any subscription in the moving plan.
