Construction Handover Questions Checklist

Establish which parts of the property are being handed to you and which remain under the control of the site team, and write the answer down area by area.

Responsibility for an area is rarely stated out loud, and both parties tend to assume it sits with the other until something happens there.

Write down anything deliberately left for later, such as external work waiting on drier weather, and record it as deferred rather than as missed.

Deferred work that is never labelled as deferred quietly becomes an argument about whether it was ever included at all.

Ask whether any area is not to be used yet and what has to happen before it can be, recording the answer against each area rather than in general.

Where an area is said to be unusable for a technical reason, ask a qualified professional what that reason is rather than assuming it is precautionary.

Note which items left on site belong to you and which are being taken away, including surplus tiles, flooring, paint and offcuts kept for later repairs.

Surplus material matched to what was installed is very difficult to obtain again once the job has been cleared.

Find out what protection is being taken away at handover and what is being left in place, since protective film left on a surface can become difficult to remove.

Protective coverings are removed by whoever is last on site, and anything they leave behind becomes your problem without anyone saying so.

Record the condition of shared areas, boundaries and neighbouring surfaces at the moment the site team leaves, with photographs taken the same day.

Attribution of damage outside the property becomes impossible once access has ended and everybody has moved on to other work.

Ask to be shown how the heating controls are actually operated rather than being handed the literature for them, and take notes in your own words as you watch.

Written instructions describe a range of installations, while the demonstration describes yours, and the difference is usually where the confusion sits.

Ask someone to demonstrate the ventilation and extract equipment, including how any filter is reached, and note where each unit draws from and discharges to.

Ask a qualified professional to demonstrate ventilation equipment and to explain what should not be covered, blocked or adjusted.

Have every operable window, rooflight and external door opened and closed in front of you, and note which key, handle or pole is needed for each one.

Openings high up or awkwardly placed are frequently operated once during the works and then not again until you need them.

Have the hot water arrangement operated in front of you from a cold start, and note what the person doing it touches and in what order.

Do not operate or adjust unfamiliar system components yourself; ask a qualified professional to demonstrate and explain them.

Record a short video of each demonstration with the person narrating what they are doing, since notes taken at handover rarely make sense a long way afterwards.

A narrated video answers the questions you did not know to ask at the time, which is most of them.

Ask what the first thing to look at would be if each system stopped working, and write the answer down while you are calm rather than when you need it.

The obvious first check is obvious only to the person who installed the system, and it is often the most useful sentence they can give you.

Ask to be shown where each incoming service can be isolated, and walk to every point yourself so that you could find it in the dark.

Ask a qualified professional to explain what each isolation point does, and do not operate anything you have not been shown.

Note which isolation point serves which part of the property, since a project often leaves more isolation points than the property originally had.

Extra isolation points are added quietly during works, and an unmapped one is as unhelpful as no isolation point at all.

Ask whether any isolation point has been moved, boxed in or covered during the work, and record where it now sits and how it is reached.

Points that moved during construction are the ones nobody thinks to mention, because the site team has known the new position all along.

Note anything that needs a tool or a key to isolate, ask where that tool is kept, and keep it with the rest of your handover material.

A valve that needs a key you do not have is functionally the same as a valve you cannot reach.

Before the property is ever left empty in cold weather, ask what should be isolated, and record the answer alongside the positions of the relevant points.

What should be isolated or drained varies by installation and must be confirmed with a qualified professional rather than assumed.

Write down what each labelled way in the consumer unit is said to serve, and note any that nobody present can account for.

Do not open, test or alter electrical equipment; record the labelling as it was described to you and raise gaps with a qualified professional.

Bring everything acknowledged as outstanding into one written list, and ask for that list to be confirmed back to you rather than kept in someone else's notebook.

Items held in several places are worked from none of them, and a confirmed list is the only version that survives the end of a project.

Ask what each outstanding item is waiting on, whether weather, material availability or another party, and record the reason beside the item itself.

A reason recorded against an item tells you who to chase, while an item on its own tells you nothing at all.

Agree how return visits are arranged, who will be present and how you will be told in advance that somebody is coming to the property.

Return visits are the part of a project everyone assumes will be easy, and they are usually the part that stalls.

Ask which outstanding items need the property empty or a room cleared, so that you can plan around them rather than being asked at short notice.

Items needing disruptive access are the ones most likely to be postponed indefinitely once you have moved back in.

Note who is responsible for each outstanding item where more than one trade is involved, since shared items are the ones that sit untouched.

Where two trades each believe the other is attending to something, nobody attends to it and neither party is being unreasonable.

Record anything you were told would be attended to that does not appear on the written list, and ask for the list to be corrected before you accept it.

The gap between what was said and what was written is where most post handover disagreements begin.

Write down a single named point of contact for the project, and ask who takes that role over if the person named is no longer involved.

Projects change hands quietly, and a contact route that depends on one individual usually breaks without any announcement.

Check which trade installed which system, and whether you contact them directly or always through the main point of contact.

Going direct when you should not, or vice versa, is a common reason a simple request goes unanswered for a long stretch.

Note the contact route for anything urgent when the office is closed, and ask what would be treated as urgent from their side rather than yours.

Both parties usually have a different definition of urgent, and discovering that in the middle of an incident helps nobody.

Ask which parts of the work were carried out by a specialist whose paperwork and support come from them rather than from the main contractor.

Specialist items often have a support route that bypasses everybody you have been dealing with for the whole project.

Record a name against every installed system in your notes, since a system with nobody attached to it becomes an orphan the first time something goes wrong.

Attribution recorded on the day is far easier than reconstruction from memory once the project has ended.

Ask how something noticed later should be raised, and agree that it goes in writing rather than by telephone so that a record exists on both sides.

Written reports create a shared history, which matters far more after handover than it did during the work.

Ask which installed systems generate paperwork of their own, note who issues each one, and tick off what has physically reached you against that list.

Whether any paperwork is owed for a given installation is a question for the qualified professional who carried out the work and for the relevant local authority.

Ask what registration has to be completed for cover on installed equipment, who carries it out, and record the name of whoever told you.

Registration is frequently assumed to have been done by the other party, and the assumption only surfaces when cover is called on.

Find out what actions on your part could affect cover on an installed item, and keep that list somewhere you will actually see it.

Cover conditions are usually reasonable and rarely read, and most of them concern ordinary things owners do without thinking.

Note which paperwork comes from a manufacturer and which from an installer, since the two answer very different questions later on.

Manufacturer material describes the product while installer material describes what happened here, and confusing them wastes time.

Ask what should be sent to your insurer or lender about the completed work, and then confirm the answer with them directly.

Insurance and lending requirements are matters for those organisations and must be confirmed with them rather than settled on site.

Keep a short list of anything you were told would follow, with the name of the person who said it, since an unattributed promise is very hard to pursue afterwards.

The willingness to chase paperwork declines sharply on both sides once the project is over, so the list has to exist now.

Ask what the site team expects to happen as new materials dry and settle, and write it down so that ordinary movement is not mistaken for a fault.

Knowing what was predicted lets you tell the difference between something anticipated and something worth reporting.

Check which surfaces should not be cleaned in the usual way while they are new and what should be used instead, recording the answer surface by surface.

Ask the supplier or the installer what a new surface will tolerate while it is settling, rather than treating it as you would an established finish.

Note what to look at the first time it rains heavily and the first time the heating runs properly, and plan a deliberate walk round for each.

Both events reveal things that are simply invisible in dry, mild conditions, and both tend to happen when nobody is paying attention.

Establish whether anything needs to be operated from time to time in order to keep working, such as a valve or a vent, and record what and where.

Ask a qualified professional to demonstrate anything you are told to operate rather than working it out from written material.

Record any smell, sound or condensation you notice once you are living with the work, noting the conditions and what was running at the time.

Context is what makes an observation useful to somebody who was not there, and it is the part everybody forgets to write down.

Find out what should happen before the property is left empty for a long stretch, and record it now while somebody is still there to be asked.

Advice about an empty property is easy to obtain at handover and surprisingly hard to obtain once the project has closed.
