Before refurbishment or demolition

Do I need an asbestos survey before building work?

Usually the question isn't whether the building might contain asbestos, but which materials the work will actually disturb. This page sets out what different projects typically involve, and which survey tends to follow.

What decides the survey scope

Asbestos was used in UK construction products until 1999, so buildings from before 2000 may contain it in places that only become relevant once the fabric is opened up. The starting point is the proposed work: which rooms are affected, what is being removed, and which walls, ceilings, floors and service routes will be cut into. A survey scoped to that work gives the contractor the information they need without paying for areas nobody is going to touch.

Where intrusive work is planned, a Refurbishment & Demolition Survey of the affected areas is the usual scope. Where only one or two materials are in question — a ceiling finish or a floor covering, for example — sampling and laboratory analysis may be enough. A Management Survey is for occupied buildings that are staying as they are, and is not designed to cover works.

This page is general guidance. Requirements differ between buildings and projects, so we confirm the appropriate scope with you before anything is booked.

Common projects and what they disturb

Kitchen replacement

Stripping out a kitchen usually means removing units and splashbacks, lifting flooring, cutting into walls and ceilings and altering gas, water and electrical services. The scope of a survey should follow that work rather than the room label.

Typically considered

  • Textured coatings on ceilings and, occasionally, walls
  • Vinyl or thermoplastic floor tiles and the black bitumen adhesive beneath them
  • Boarding behind or above units, and boxing around service routes
  • Panels or pads historically used beneath sinks and around boilers
  • Wall and ceiling substrates opened up for new pipework or cabling

Bathroom refurbishment

Bathrooms are small but intrusive projects: tiling is removed, boxing is opened, ceilings are altered for extraction and lighting, and soil and supply pipework is re-routed.

Typically considered

  • Ceilings, including textured finishes and any boarded false ceiling
  • Boxing and panelling concealing pipework and cisterns
  • Floor coverings and adhesives beneath them
  • Wall linings disturbed by new fittings or re-routed services

Loft conversion

A conversion opens the roof void, alters ceilings below and takes new services through the structure. Materials in a roof space are often undisturbed until this point.

Typically considered

  • Existing insulation and any debris within the void
  • Water tanks, flues and pipe insulation in the loft
  • Ceilings below the void, including textured coatings
  • Soffits, fascias and roofing products where the roofline is altered
  • Penetrations formed for new cables, pipework and ventilation

House extension

Most extension risk sits at the junction between the existing building and the new structure, where the original fabric is cut, opened or removed.

Typically considered

  • The existing external wall where openings are formed
  • Ceilings and floors affected at the connection
  • Soffits, fascias, gutters and any outbuilding or garage being removed
  • Service routes diverted through the existing property

Knocking through or removing a wall

Removing a wall disturbs the wall itself and everything fixed to or running through it. Whether a survey is appropriate depends on the construction and age of the building and what is being removed — not on the wall alone.

Typically considered

  • Wall linings and any board finish
  • Ceilings either side of the opening, which are usually cut back
  • Floor finishes at the threshold
  • Cables, pipework and any boxing running within the wall

Rewiring

A full rewire is one of the most widely distributed intrusive jobs in a property: chases are cut, ceilings are drilled, risers and voids are opened and old fittings are removed across every room.

Typically considered

  • Chased and drilled walls and ceilings across the whole property
  • Boxing, risers and service cupboards opened for cable routes
  • Ceiling voids and loft spaces used to run cabling
  • Older electrical equipment, panels and backing boards removed as part of the works

Plumbing and heating work

Boiler replacements, new heating circuits and bathroom re-plumbing all cut into building fabric even where the visible work looks limited.

Typically considered

  • Pipe insulation on existing runs, particularly in older systems
  • Flues, boiler cupboards and the linings around them
  • Floors lifted and joists notched for new pipework
  • Boxing and duct routes opened between floors

Ceiling replacement or over-boarding

Ceilings are one of the most common reasons a survey is arranged, because the finish itself may be the material in question.

Typically considered

  • Textured coatings, which cannot be identified by appearance alone
  • Board finishes and any suspended or false ceiling system
  • The ceiling void, insulation and services above
  • Boxing around beams and service runs

Garage conversion

Attached and detached garages frequently use different materials from the house. A conversion typically removes or alters the roof, ceiling and internal linings.

Typically considered

  • Roof sheets, including corrugated cement products
  • Ceiling linings and any internal boarding
  • Panels to walls, doors and gable ends
  • Soffits, gutters and downpipes altered as part of the works

None of the materials listed above necessarily contains asbestos. Appearance alone cannot confirm it — laboratory analysis of a sample is the only reliable answer. Our material identification guides explain where each product was historically used.

Asbestos surveys before building work — questions we're asked

My builder has asked for an asbestos survey — what do they actually need?

In most cases the contractor needs asbestos information covering the areas and materials the work will disturb, so they can plan the job and brief their operatives. That is normally a Refurbishment & Demolition Survey scoped to the works, though a smaller job affecting one material may only need sampling and analysis. Send us the scope of works and we will confirm what is appropriate.

Does every property built before 2000 need an asbestos survey?

No. Asbestos was widely used in UK buildings until it was banned in 1999, so a pre-2000 building may contain asbestos, but the requirement depends on the circumstances. The Control of Asbestos Regulations 2012 place a duty to manage asbestos on those responsible for non-domestic premises, and separately require that asbestos is identified before work that may disturb it. Whether a survey is appropriate depends on the building, the proposed work and any information already available.

Can building work start before the survey is done?

Where intrusive work could disturb materials that have not been identified, the sensible sequence is to establish what is present first — the results may change the method, the programme or the cost. We can usually work to a start date if you tell us when the contractor is due on site.

Is a management survey enough before refurbishment?

Usually not. A management survey records materials that can be seen and reached without breaking into the fabric, so it is designed for occupied buildings rather than for works. Where walls, ceilings, floors or services will be opened, an intrusive survey of those areas is normally the appropriate scope.

Do I need the whole property surveyed, or only the rooms being worked on?

The survey should match the work. If a single kitchen is being replaced, the scope can be limited to that area and the services affected. If a whole-house refurbishment or rewire is planned, the scope needs to follow it. We agree the boundaries with you in writing before the visit.

What if we have already started and uncovered something?

Stop work in that area, keep people away from it and avoid disturbing it further. Send us a photograph and a description and we will advise on sampling or a survey of the affected area.

How much does a survey before building work cost?

Refurbishment surveys start from £400 and demolition scopes from £500, with the final figure depending on the size of the property and the extent of the works. Guide prices for every survey type are on our cost page.

Do you carry out the removal work as well?

No. Elements Surveying Group is an independent asbestos consultancy and does not sell asbestos removal, so the findings and recommendations in a report carry no commercial incentive to generate removal work.
