Renovation Survey Preparation Checklist

Note which parts of the property cannot be reached without a key, a ladder or another person present, and arrange for those before the date is agreed.

A loft, a cellar, a shared meter room and a locked outbuilding are the four places most often missed simply because nobody could open them during the visit.

Write down where the loft hatch, meter cupboards, main stopcock and consumer unit are, so the visit is not spent hunting for them.

These are usually the first things asked for, and in many older properties at least one of them has been boxed in or papered over by a previous owner.

Check whether any part of the building is shared, tenanted or occupied by someone else, and note what notice that person may be owed before entry.

Flats, converted houses and annexes often involve someone else's agreement for access to roofs, risers, cellars and communal areas.

Notice and entry obligations vary by tenure and location; ask a qualified professional what applies to your arrangement before making the appointment.

Note whether the rear, side return, flat roof or boundary walls can be reached from your own land, and who controls the ground a ladder would stand on.

External access is often the part of a survey that quietly gets dropped, and the outside of a wall usually explains what is happening inside it.

Record any area you have been told not to enter, such as a fragile roof covering or a floor that someone has already propped, and raise it at the start.

Do not enter or test such an area yourself; describe it and let a qualified professional decide how it should be approached.

Confirm who from your household will be present, and sort out pets, parking and any entry phone or gate code in advance.

In terraced streets and flats, parking and door entry are ordinary reasons a visit starts late and finishes unfinished.

Empty the space under sinks and inside the boiler or cylinder cupboard, since the pipework and connections there are almost always asked about.

These cupboards hide joints, isolation valves and old alterations, and they are among the easiest places to learn something useful about the services.

Move stored boxes away from external walls in the loft and garage so the wall surfaces and roof timbers can actually be seen.

Stored belongings against a wall both hide staining and cause it, so clearing them a little in advance gives a truer picture.

Consider lifting a corner of fitted carpet in a room you already intend to strip, rather than in every room, and note what is underneath.

One deliberate opening in a room that is coming up anyway tells you more than guessing across the whole house, and it gives up nothing you intended to keep.

Photograph anything you intend to cover back up before the visit, and keep the images with the date they were taken.

Dated owner photographs of a floor void, a wall tie or an old repair are often the only record that survives once finishes go back on.

Leave a recent repair unpainted where you can, so it is visible during the visit rather than hidden under fresh decoration.

Fresh paint over a repair invites more questions than it answers, and it can make a settled old defect look like a new one.

Ask in advance whether anything will need opening up, who would carry that out, and who makes good afterwards.

Opening up finishes in older buildings can disturb materials that need specialist handling; ask a qualified professional what should be established before anything is cut into.

Gather any previous survey, valuation or condition report on the property, including whatever you were handed when you bought it.

An earlier report gives a dated baseline, and a defect that was already noted then reads very differently from one that has just appeared.

Find service records for the heating system and any paperwork left behind by earlier installers in the meter cupboard, loft or airing cupboard.

Installers commonly leave a card, a label or a folded sheet near the appliance, and it often names what was fitted and when it was last looked at.

Look for drawings of past alterations, even rough ones, and note which parts of them appear to have been built as drawn.

Drawings frequently differ from what was actually constructed, so flagging your uncertainty is more useful than presenting them as fact.

Retrieve the deeds pack, lease or managing agent pack where the property is leasehold or shares structure or drainage with a neighbour.

Tenure documents can restrict what may be altered and who must be told; ask a qualified professional to read them before your scope is fixed.

Note any paperwork you know exists but cannot find, so it can be requested from the previous owner, the managing agent or the local authority.

Naming the gap early gives time for a request to be answered, which is rarely possible once decisions are already being made.

Note the supply arrangements the property already has, such as what fuel the heating uses and whether drainage appears to be shared.

Supply and drainage arrangements shape what is realistic far more than the finishes do, and they are usually visible on paperwork you already hold.

Write down roughly when each part of the building appears to have been added, and how you know — being unsure is worth recording too.

Different eras of construction behave differently, and the junction between an original wall and a later addition is where problems tend to gather.

List alterations made since you moved in, including who carried them out and whether any paperwork was left behind.

Recent work is the easiest history to reconstruct and the one most likely to be forgotten during a walk-round.

Note anything a previous owner, neighbour or agent told you about the building, and mark it plainly as hearsay rather than as fact.

Second-hand accounts are worth passing on, but presenting them as established fact can send a professional looking in the wrong place.

Record which rooms have changed use over time, such as a garage turned into living space or a bathroom moved to a different floor.

Changes of use usually mean services were rerouted and floors or walls were altered, which is exactly what someone will want to trace.

Note where you believe pipework or cabling was rerouted, and say plainly that it is a guess if that is what it is.

A rough owner sketch of suspected routes saves time even when it turns out to be wrong, because it shows what has been altered.

Describe any past repair you are aware of, such as a wall retied, a roof patched or a floor relaid, and whether you hold any record of it.

Knowing that an area has been repaired before changes how its current condition is read, and old repairs are easy to miss under decoration.

Point out cracks you have watched over time, and say what has changed about them rather than offering a measurement or an explanation.

Whether a crack is stable or moving matters more than its appearance at a single moment, and only you have watched it over time.

Cause and significance of cracking is a structural question; ask a qualified professional to assess it rather than drawing your own conclusion.

Note doors and windows that stick, and whether they stick all year round or only in particular weather.

Seasonal sticking and permanent sticking suggest different things, and the seasonal pattern is something only the household can report.

List rooms that feel cold, draughty or slow to warm up, and note which external walls or unheated spaces they sit against.

Mapping comfort complaints onto the building's outside faces gives a much better starting point than a general complaint about being cold.

Describe smells you notice and exactly where, such as a musty cupboard on an outside wall or a drain smell near a gully, and when they are strongest.

If you ever smell gas or burning, treat it as an urgent matter for the relevant emergency service or supplier rather than a note for a survey visit.

Record noises the building makes, such as pipes knocking when the heating starts or a rattle in wind from one direction, and what sets them off.

Intermittent noises almost never happen during a visit, so the household's account of what triggers them is the only evidence available.

Note where condensation forms first on cold mornings, and whether it appears on the glass, the reveals or the wall surface itself.

Where moisture shows up first, and on which surface, is an observation an owner can make repeatedly and a visitor can make only once.

Agree in writing what the visit covers, what it excludes, and whether concealed elements sit outside its scope.

Almost every dispute about a survey comes down to an expectation about scope that was never written down by either side.

Ask whether the visit is a general overview or focused on the parts you intend to change, and say clearly which of the two you want.

An overview and a focused look at a proposed alteration are different exercises, and asking for the wrong one wastes the visit.

Decide and record the questions you most want answered, and put them in order so the important ones are reached first.

Visits run out of time, and the questions asked at the door tend to be answered while the ones saved for the end are not.

Check what information the visiting professional needs from you beforehand, such as access arrangements, a rough floor sketch or your list of concerns.

Sending the material in advance often changes what gets looked at, because it lets someone arrive already knowing where to start.

Ask what would prompt a suggestion that a further specialist look is needed, and who would be responsible for arranging that.

Further investigation of structure, services, drainage or hazardous materials belongs with appropriately qualified professionals rather than with you.

Note any part of the property you would rather was not disturbed, and raise it before the visit rather than during it.

Fragile decoration, a home office in constant use or a sleeping shift worker are all easier to work around when flagged in advance.

Ask what form the written output takes, whether it includes photographs, and whether its limitations will be stated within it.

A report that names what it did not look at is far more useful than one that quietly leaves those areas out.

Decide who else will need to read it — a co-owner, a lender, a managing agent — and ask whether it may be shared with them.

Reports are often addressed to one party only, and finding that out afterwards can mean the whole exercise has to be repeated.

Write down which findings you intend to act on now and which you are parking, and keep that decision alongside the report itself.

Parked items get forgotten, then rediscovered at the worst moment; recording the decision keeps them retrievable later.

Ask which findings are observations and which are professional opinion, so you can tell the two apart when you reread it.

Owners frequently treat a hedged opinion as a firm finding, which then sends attention and effort towards the wrong part of the building.

Note any suggestion that a different discipline should look at something, and treat it as a separate conversation to arrange rather than a footnote.

Referrals to a structural, drainage, electrical or hazardous materials specialist should be followed up with a suitably qualified professional locally.

Keep the report together with your own dated photographs and walk-round notes, since the two together are far more useful than either alone.

Your notes carry the seasonal and historical detail; the report carries the professional reading of it. Separated, both lose value.
