Part C of Schedule 1 to the Building Regulations 2010 requires that the walls, floors and roof of a building adequately protect the building and the people who use it from harmful effects caused by ground moisture, precipitation, condensation and spillage from sanitary fittings. Approved Document C is the England guidance that sits under it. Scotland's equivalent is mandatory standard 3.4, which requires that a building is designed and constructed so there is no threat to the building or to the health of the occupants from moisture penetration from the ground, with separate guidance for ground-supported concrete floors and for suspended timber floors.

Those rules describe what a new floor must achieve, not what an old one actually does. A solid floor poured before membranes were routine may be passing moisture upwards quietly for years without anyone noticing, because the covering over it was permeable. Glue a timber floor to that slab and the moisture has nowhere to go, so the adhesive lets go and the boards cup. This is why a fitter should be testing the slab rather than looking at it, and why the honest answer to when the floor can be laid over a fresh screed is after a test, not after a fixed number of days.

A suspended timber floor has the opposite failure mode: it depends on air. The Scottish guidance for suspended timber floors expects permanent ventilators in the external walls, and the same principle applies to any ventilated void. Blocking the airbricks with a new patio, a raised bed or a bank of decking starves that void of air, and damp, poorly ventilated timber is how a good new floor is ruined from below. Before boards go down, a fitter should also be checking for movement in the joists, since a floor that bounces will eventually show it in the finish.

HSE's position on age is blunt: asbestos may be part of any commercial or domestic building built or refurbished before the year 2000, and it was widely used in homes until 1999, when it was banned. Under an old timber or tiled floor the candidates are the bitumen adhesives and mastics used to stick blocks and tiles down, and floor tiles themselves, since asbestos was added to PVC and thermoplastic floor tiles, stair nosings, sheet materials and screed materials. If any of that turns up when the carpet comes off, HSE's instruction is to stop work immediately, confirm what the material is or assume it is asbestos, and carry out a risk assessment. HSE also tells householders not to try to repair or remove asbestos materials themselves without training for non-licensed asbestos work.

Fitting a wooden floor is not itself work that needs building control approval in England and Wales, where gov.uk lists the alterations that do, such as replacing a fuse box, installing a bathroom involving plumbing, replacing windows and doors, replacing roof coverings and installing or replacing a heating system. The picture changes if the work becomes structural, for example if joists are cut, notched or replaced, or if a floor is opened up as part of a larger project. Scotland runs a different system entirely: mygov.scot lists building or removing load-bearing walls and other structural elements among the work that needs a building warrant, and a warrant is valid for three years. Northern Ireland works to the Building Regulations (Northern Ireland) 2012 and its own technical booklets. Ask your fitter to say plainly whether anything they propose touches the structure.

Most of the craft in a timber floor is invisible once it is down. Over a slab, the options are a levelling compound to take out undulations, a liquid surface damp-proof membrane where the original protection cannot be relied upon, or a battened or ply deck that lifts the timber clear and gives something to fix into. Over joists, a ply overlay of the right thickness turns a set of springy floorboards into a flat, stable deck. The adhesive matters too, because the manufacturer specifies which products are compatible with their boards and with any membrane, and mixing systems is a common cause of a claim being refused.

Underfloor heating changes the specification rather than ruling timber out. Engineered boards are the usual answer because the cross-laid core moves less as the floor warms and cools, and thinner boards let heat through more readily than thick solid stock. Ask the fitter to confirm in writing that the specific product is approved for use over the specific heating system, and that the commissioning sequence will be followed: the screed brought up and back down before laying, and the floor brought up to temperature gradually afterwards rather than being switched on hard on the first cold morning.

Timber takes up and gives off moisture with the air around it, so a wooden floor in an occupied British home is never completely still. The pattern is predictable: in winter the heating runs, indoor air gets drier, and fine gaps open between boards; in a humid summer the boards take moisture back and the gaps close. A floor that has been acclimatised properly and laid with the correct expansion allowance absorbs that cycle without complaint. One laid tight to the skirting boards in a damp autumn can lift or peak when it expands with nowhere to go.

Two practical habits help. Keep the house at a reasonably steady humidity rather than swinging between a closed-up, heavily heated week and an open-windowed one, and do not let a rush of drying happen just after fitting, which is what tends to happen when a room is redecorated, the heating is turned up and the windows are shut. If a new floor is going in over winter, it is also worth agreeing when the heating will be running during the work, because acclimatising boards in an unheated room and then heating it hard is asking the floor to move twice.

Comparing timber flooring quotes is really comparing what each fitter proposes to do below the boards. One price may cover lifting the old covering, a ply overlay, a moisture test and new skirting boards; another may assume the room is ready and the existing skirting stays. Ask each fitter to state the base preparation, the fixing method, the expansion allowance and who is redecorating afterwards, and the numbers become comparable.

LokalMatch is where that comparison starts. You describe the flooring job once, including the room sizes, whether the floor is solid or suspended timber, the age of the property and anything you already know about what is under the current covering, and matched flooring pros covering your postcode contact you directly. The professionals pay for the requests they receive. LokalMatch does not lay floors, does not set prices and does not vet, rank or recommend any contractor, so the references, insurance and written specification are still yours to check.
