Asbestos in London Homes: Survey, Removal and Renovation Safety

Asbestos was used in a wide range of building materials until it was banned in the UK in 1999 (chrysotile/white asbestos) and 1985 (blue and brown asbestos). Common locations in London domestic properties:

• **Most commonly found:**
• •**Artex and textured coatings:** White textured ceiling coatings applied from the 1960s–1990s commonly contained chrysotile (white) asbestos. Heavily textured 'popcorn' ceilings and swirled finishes are the most likely to contain ACMs. Flat Artex-style coatings on ceilings may also contain asbestos.
• •**Floor tiles and adhesive:** Vinyl floor tiles from the 1960s–1980s and the bituminous adhesive used to fix them commonly contain asbestos. Grey/black bitumen adhesive beneath carpet or vinyl is high-risk.
• •**Pipe lagging and boiler insulation:** Lagging on older pipes (pre-1985) and insulation on older boilers may contain crocidolite (blue) or amosite (brown) asbestos — the most hazardous types.
• •**Soffits and fascias:** Some pre-1990 external soffit boards and internal ceiling boards contain asbestos cement.
• •**Roof sheets:** Corrugated asbestos cement sheets on garage roofs and outbuildings. Common on inter-war and post-war London garages.

• **Less commonly found but possible:**
• •Insulating board behind storage heaters and in fire-surrounds
• •Rope seals around boiler doors
• •Sprayed asbestos coating on structural steelwork (rare in domestic properties; more common in commercial)
• •Some older roofing felts

**The key principle:** You cannot identify asbestos by sight. An Artex ceiling or vinyl tile that looks normal may or may not contain asbestos. The only reliable identification is laboratory testing of a sample, carried out as part of an asbestos survey.

Two types of asbestos survey are defined in the HSE guidance (HSG264):

**Management Survey (Type 1 / Domestic Survey):** A non-intrusive survey to identify and assess the condition of reasonably accessible ACMs that may be disturbed during normal occupation and maintenance. The surveyor visually inspects the property and takes samples for laboratory analysis where ACMs are suspected.

Suitable for: properties where you want to understand the asbestos risk profile before starting work, or where low-risk renovation (decorating, floor covering replacement) is planned.

Cost: £150–£350 for a standard London Victorian terrace.

**Refurbishment and Demolition Survey (Type 2 / R&D Survey):** An intrusive survey required before any significant structural, demolition, or refurbishment work. The surveyor accesses all areas that will be disturbed — including above ceilings, behind wall linings, beneath floors, and within service voids. This survey must be completed before stripping-out work begins.

Suitable for: any renovation project involving opening walls, removing ceilings, strip-out, structural works, or demolition.

Cost: £300–£700 for a standard London Victorian terrace (R&D Survey with lab analysis of samples).

• **When you need an asbestos survey:**
• The HSE guidance requires that a Refurbishment and Demolition Survey is carried out before any intrusive renovation work on a pre-2000 property. For a Victorian terrace, this means an R&D Survey before:
• •Loft conversion (roof space works)
• •Extension (demolition of existing rear wall)
• •Full refurbishment (ceiling removal, wall opening)
• •Structural alterations

Your contractor should request the asbestos survey results before pricing and before starting work. A reputable contractor will not begin intrusive work on a pre-2000 property without asbestos information.

Not all asbestos removal requires a licensed contractor. The HSE classifies asbestos work by risk level:

**Licensed work:** Required for the removal of the most hazardous ACMs — pipe lagging, boiler insulation, sprayed coatings, insulating board (AIB), and asbestos cement roofing where the work is not short duration. Must be carried out by an HSE-licensed asbestos removal contractor. A licensed contractor is legally required to notify the HSE and the client's GP of the work, use full PPE and RPE, and provide a clearance certificate after removal.

**Notifiable non-licensed work (NNLW):** Includes removal of lower-risk ACMs where the work is sporadic and low-intensity — for example, minor drilling or cutting of asbestos cement, removal of textured coatings (Artex). NNLW is not licensed but must be notified to the HSE, medical surveillance is required, and records must be kept.

**Non-licensed work:** Low-risk, occasional work with ACMs — such as removing a single asbestos cement roof sheet in good condition. No license required but safe working methods must be followed.

**What happens when asbestos is found during a London renovation:** In most Victorian terrace renovations, the most commonly found ACM is Artex on ceilings. This is low-risk when intact but must be treated carefully during renovation:

• •If the Artex ceiling is being overboarded (new ceiling board fixed below the existing) rather than removed, the risk is low — provided drilling is minimised.
• •If the Artex ceiling is being stripped, the asbestos content must be confirmed by survey. Removal of confirmed asbestos Artex requires either a licensed contractor (for high-risk scenarios) or NNLW procedures (for low-risk removal).
• •In most cases, vinyl floor tiles and adhesive are the higher-risk material — disturbing black bitumen adhesive releases fibres and requires careful management.

• **Cost of asbestos removal in London:**
• •Artex ceiling removal (asbestos-confirmed, single room, NNLW): £400–£900
• •Vinyl tiles and adhesive removal (per room, specialist contractor): £500–£1,500
• •Pipe lagging removal (licensed): £1,500–£4,000 depending on extent
• •Asbestos cement garage roof removal (licensed): £1,200–£3,000
