HMOs and converted flats — a non-domestic duty in a domestic building.
A licensed HMO or a Victorian house converted into flats is a domestic-looking building with a non-domestic duty under Regulation 4 of CAR 2012. Councils increasingly ask for the asbestos register at licence renewal, and insurers query it after any incident.
Overview
What actually matters in hmos & converted flats.
The moment a house becomes a multi-let property, the communal parts — hallways, staircases, shared kitchens, meter cupboards, roof spaces — carry a non-domestic duty to manage asbestos. The landlord (or the freeholder if the property is leased) is legally the dutyholder.
Councils operating selective and additional licensing schemes increasingly ask to see an asbestos register at the point of licence application or renewal. A missing register is not usually grounds for refusal but is a very common inspection finding.
Converted flats typically sit in Victorian, Edwardian or interwar houses — so the pattern of ACMs is the same as the underlying stock, layered onto later communal-area upgrades (fire doors, hardwired smoke alarms, communal Artex ceilings).
Era-by-era context
What was original, and what got added later.
Underlying build (pre-1980)
Original fabric plus mid-century refurbishments — Artex, AIB airing cupboards, cement flues, vinyl tiles.
Conversion works (1980s–2000s)
AIB fire-lining to staircases, communal Artex, cement pipe boxing, textured coatings to soffits.
Ongoing turnover
Void refurbishments, kitchen and bathroom replacements — each cycle risks disturbing previously-managed ACMs.
Typical asbestos locations
Where we find it most in hmos & converted flats.
Communal staircase Artex
Textured coatings on stair ceilings and soffits — safe intact, hazardous when redecorated aggressively.
AIB fire-lining to flat entrance doors and staircases
Added during conversion to meet Building Regs — often behind later plasterboard.
Meter cupboard millboard
Communal electric and gas meter cupboards frequently lined with asbestos millboard.
Airing cupboards inside individual flats
AIB panels around cylinders — landlord duty extends where the airing cupboard is a communal or shared asset.
Kitchen and bathroom vinyls
Void refurbishments repeatedly reveal chrysotile-bearing floor tiles under laminate.
Roof space and dormer fire-lining
Asbestolux or millboard behind timber cladding in loft conversions completed pre-2000.

HMOs & Converted Flats — the questions clients ask us first.
Does an HMO need an asbestos survey by law?
Yes — the communal parts fall under the non-domestic duty to manage in Regulation 4 of CAR 2012. A management survey plus a written plan is the minimum standard of care.
Who is the dutyholder — landlord or freeholder?
Whoever holds the repairing obligation for the communal parts under the lease. In most HMOs that is the operating landlord; in tenanted freeholds with a management company it may be shared.
