If you're about to rewire, knock through a wall or convert the loft, the survey that matches the job is a refurbishment & demolition (R&D) survey of the areas being worked on. A management survey (often called a "maintenance survey") is designed for living in a building as it is: it is non-intrusive and will not look inside the walls, floors and ceilings your builder is about to open up.
Key takeaways
- Management survey = normal occupation, non-intrusive, produces an asbestos register.
- R&D survey = before work that disturbs the fabric; intrusive, the area must be empty, and it only needs to cover where the works are.
- A non-intrusive survey cannot "confirm" what it can't reach; unsampled or inaccessible areas are presumed to contain asbestos.
- In an owner-occupied home you are not legally responsible for contractors' asbestos risk, but their employers must assess for asbestos (or presume it) before starting work.

What's the difference between a management survey and a refurbishment & demolition survey?
Both are defined in HSE's survey guidance (HSG264). Forums still use the old names: "management survey (Old Type 2)" and "refurbishment survey (Old Type 3)" [1].
| Management survey | Refurbishment & demolition (R&D) survey | |
|---|---|---|
| Purpose | "to allow you, as the dutyholder, to produce an asbestos register" for normal occupation [2] | To "locate and identify ACMs, including those hidden within the building fabric" before works [2] |
| How intrusive? | Minor, non-destructive; areas not accessed are presumed to contain asbestos [2] | "destructive inspection"; the area "must be vacated during the survey" [2] |
| Scope | All accessible rooms, corridors, stairs, loft, etc. [2] | Only the areas affected by the planned work |
| After the survey | Register used to manage materials in place | Surveyor confirms area "fit for reoccupation" [2]; materials found are dealt with before works |
| Ballpark, 3-bed house (2026) | £200–£400 [3] | £350–£600 [3] |

ACM means "asbestos-containing material". In a 1930s–1970s house, typical suspects are Artex or other textured ceilings, vinyl floor tiles, asbestos insulating board (AIB) around boilers, airing cupboards and soffits, and cement garage roofs. HSE notes asbestos can be present in "any building built or refurbished before 2000" [4].
Which asbestos survey do I need for a rewire, knock-through or loft conversion?
| Your project | Survey usually appropriate | Why |
|---|---|---|
| Buying a house, no works planned yet | Management survey (with samples) | Tells you what's there and its condition |
| Full rewire | R&D survey of affected rooms, voids and ceilings | Chasing walls and lifting floorboards disturbs the fabric |
| Knock-through / removing a wall | R&D survey of that wall, adjoining ceilings and floors | Demolition of fabric; textured ceilings are often cut |
| Loft conversion | R&D survey of loft, ceilings below and any boarding or flue | New floor joists, stairs and openings in ceilings |
| New kitchen or bathroom | R&D survey of that room | Floor tiles, boxing-in, panels behind units |
| Replacing a garage roof | R&D survey of the garage (or a sample of the sheets) | Sheets are removed and the roof structure exposed |
| Fitting a smoke alarm or a few shelves | A sample of the specific material, or presume and take precautions | A small, defined disturbance |
One reply on r/HousingUK summed it up: "Before a rewire takes place the contractors are legally obligated to conduct a refurbishment survey... The survey is intrusive and gains access into the fabric of the building" [5]. Strictly, the legal duty is on the contractor's employer to assess or presume (see below), but in practice that usually means an R&D survey.
Mumsnet users worry that the "R/D survey is a very messy job" [6]. It does involve drilling, lifting and opening up, which is why it's best done when the rooms are empty and before decorating, not after.
Quick decision tree
- Will anything be drilled, chased, cut, lifted or knocked down? No → a management survey (if you want one) is enough. Yes → go to 2.
- Is the work limited to one material you can point at (e.g. one ceiling)? Yes → consider a sample of that material. No → go to 3.
- Will several rooms, voids or the loft be opened up? Yes → R&D survey of the work areas, ideally once your plans are fixed.
- Already have a management survey? Keep it: the R&D survey supplements it for the work areas, it doesn't replace it.
Can a management survey 'confirm' asbestos if it's non-intrusive?
This is a common question ("Does it confirm the presence of asbestos even though it is non-invasive?") [7], and the honest answer is: only for what it actually sampled.
- HSE: "The only way to confirm if a suspect material contains asbestos fibres is to obtain and analyse a sample of it" [2]. A management survey can sample accessible materials, such as a ceiling or floor tile, and that result is a confirmation.
- What it cannot do is confirm or rule out materials it didn't reach, such as inside a stud wall, under floorboards or behind boxing. Those areas must be "presumed to contain asbestos" [2].
- Experience alone doesn't confirm anything. A surveyor who claims to recognise asbestos by sight is giving an opinion; as one forum reply put it, "Only a sample can confirm if it actually is asbestos" [8].
So if your RICS Level 3 survey says "almost certainly contains asbestos" and you plan works, a management survey will tell you about the visible Artex and floor tiles, but your builder will still need the hidden areas checked before opening them up.
Who is legally responsible: me as the homeowner, or my builder?
This is where people get confused, partly because the site's own guides use the word "dutyholder".
- Owner-occupied houses. HSE says: "In owner-occupied domestic properties, the owners are not legally responsible for risks to contractors from asbestos" [9]. The "duty to manage" in regulation 4 applies to non-domestic premises and to "the shared parts of some domestic premises" [9], such as communal hallways in a block of flats.
- Your builder, electrician or plasterer. Under the Control of Asbestos Regulations 2012 (CAR 2012), regulation 5, an employer "must not undertake work in demolition, maintenance or any other work" that could expose workers unless they have made "a suitable and sufficient assessment" of whether asbestos is present, or, if in doubt, they assume it is present and that it "is not chrysotile alone" [10]. Assuming asbestos means pricing in full precautions, so a survey can save money.
- Domestic clients and CDM. On construction projects for homeowners, client duties are largely passed to the contractor; one forum reply notes that "CDM duties are off-loaded on to the builder/contractor for domestic clients" [1]. Check the current position on HSE's CDM pages.
- Landlords. Rented homes raise separate questions. A health and safety forum reply suggested that "If any of your works are intrusive in nature, you would need to undertake a suitable R & D survey" [11]. Take advice specific to your tenancy and property.
Being "not legally responsible" doesn't mean it isn't your problem: it's your family living in the dust. Commissioning the R&D survey yourself also means you control who does it. Peers recommend an independent surveyor, "not one by a firm that also does removals" [1].
How do I choose a surveyor for an R&D survey?
- A survey organisation accredited by UKAS to ISO/IEC 17020, which HSE "strongly recommends" [12]; check the UKAS register.
- Samples analysed by a lab accredited to ISO/IEC 17025 [12].
- If the firm isn't accredited, ask for the individual surveyor's qualifications (e.g. the BOHS P402 certificate) and references, as HSE suggests making "reasonable enquiries" [12].
- A brief that names the exact rooms and works. Our brief tool helps you write one.
FAQ
Do I need a management or refurbishment survey before a rewire? A rewire disturbs walls, floors and ceilings, so the appropriate survey is a refurbishment survey of the affected areas. A management survey won't look inside the fabric.
Is a "maintenance survey" the same as a management survey? Yes, "maintenance survey" is a common informal name. The HSE term is management survey; the old name was Type 2.
Does a non-intrusive survey confirm asbestos? It confirms only materials that were sampled and lab-tested. Areas it couldn't access are presumed to contain asbestos until inspected [2].
Do I need a survey for a knock-through in a 1960s semi? If the wall, ceiling or floor around it could contain asbestos, your builder must assess or presume it before starting [10]. An R&D survey of that area is the usual way to do that.
Is the R&D survey messy? It is intrusive, so expect holes, lifted boards and small areas opened up; the area must be vacated and declared fit for reoccupation afterwards [2]. Do it before decorating.
As a homeowner, am I legally obliged to get a survey? HSE says owner-occupiers aren't legally responsible for contractors' asbestos risk [9]. The duty to assess falls on the contractor's employer, who may ask you for a survey or price as if asbestos is present.
Should I go straight to removal instead of a second survey? Not without knowing what and where the asbestos is. HSE says materials in good condition are often best left in place [9]; an R&D survey tells you what actually has to come out for your works.
