Heritage Construction & Site Work Dust Extractors — Bath
Heritage construction & site work — Bath
V-TUF supplies H-Class and M-Class dust extraction to construction sites across Bath and North East Somerset. Bath presents the most consistent and widespread H-Class requirement of any city in the UK — the city's building stock is almost entirely Bath stone, an oolitic limestone that generates respirable crystalline silica during cutting, grinding, drilling, chasing and repointing. Unlike most UK cities where H-Class is required for specific masonry operations, in Bath H-Class is the baseline specification across the entire heritage construction programme. Bath Quays North and South, the University of Bath at Claverton Down, Bath Spa University at Newton Park and the wider residential growth programme generate construction demand. Royal United Hospitals Bath NHS Foundation Trust operates the RUH at Combe Park with active capital works requiring ICRA-compliant H-Class extraction in clinical areas.
V-TUF regularly supplies contractors working across Bath's World Heritage Site, Bath Quays and surrounding Bath and North East Somerset construction sites.

V-TUF MIGHTY HSV — 21L M-Class dust extractor
110V or 240V, H13 HEPA, 99.9% filtration, 21-litre wet/dry, autostart power take-off. M-Class specification for Bath Quays commercial new-build and university campus construction where masonry dust is not the primary COSHH risk. SKU MIGHTYHSV110 / MIGHTYHSV240.
Typical use case — Royal Crescent conservation works, Bath
A specialist heritage contractor undertaking repointing and stone consolidation on a Royal Crescent property runs MIDI H-Class units (240V, sealed filtration) for all Bath stone cutting, grinding and repointing operations — oolitic limestone generates respirable crystalline silica at levels well above the COSHH WEL during any cutting or abrasive operation. H-Class is not optional. Contractor trade account — next-day delivery to BA1 postcode.
Compliance notes for Bath construction and conservation sites
- CDM 2015 Regulation 15(2) — principal contractors must demonstrate dust control planning. In Bath's World Heritage Site, dust control is also typically a listed building consent and planning condition.
- COSHH 2002 — RCS WEL 0.1mg/m³ over an 8-hour TWA. Bath stone (oolitic limestone) contains crystalline silica — H-Class extraction is the legal minimum for all cutting, grinding, drilling and repointing operations across Bath's building stock. M-Class is not sufficient for Bath stone.
- Control of Asbestos Regulations 2012 — H-Class extraction mandatory for any work near or involving asbestos-containing materials in pre-2000 Bath buildings. Whilst Bath's heritage building stock is predominantly stone, pre-2000 non-heritage commercial properties, service infrastructure and modern elements added to Georgian properties during the 20th century frequently contain ACMs in pipe lagging, insulation and fire protection.
- Historic England guidance — conservation work on Bath's Grade I and Grade II* listed buildings requires dust control methods protecting both operatives and the historic fabric. H-Class extraction is the correct specification.
- ICRA — Royal United Hospitals Bath NHS FT — ICRA required for all works inside the RUH at Combe Park. H-Class mandatory for Type C and D work in clinical areas.
- 110V on site — all V-TUF M-Class and H-Class extractors available in 110V CTE.

Choosing the right dust extractor for your Bath site
- Any Bath stone masonry — cutting, grinding, drilling, repointing: MIDI H-Class (H14 HEPA, 99.995%) — H-Class is the legal minimum, not an upgrade
- Internal fit-out and refurbishment — no masonry work: MINI HSV (compact M-Class, tight access) or MIGHTY HSV (21L sustained M-Class)
- Pre-2000 building refurbishment with suspected ACMs: MIDI H-Class mandatory — see Control of Asbestos Regulations 2012 →
- Bath Quays and university new-build programmes: MIGHTY HSV M-Class for general dust; MIDI H-Class for any masonry or concrete cutting phases
- Works inside RUH under ICRA: MIDI H-Class mandatory for Type C and D clinical areas
- 110V site requirement: All three machines available in 110V CTE

Frequently asked questions
Why is H-Class required for all masonry work in Bath when M-Class is sufficient in other cities?
Bath stone is oolitic limestone — it contains crystalline silica. M-Class at H13 HEPA (99.9%) is not sufficient for limestone operations because the respirable crystalline silica fraction passes through at a rate that exceeds the COSHH WEL under sustained cutting, grinding and repointing conditions. H-Class (H14 HEPA, 99.995%) is the only classification that reliably controls silica exposure during Bath stone masonry operations.

Servicing, spares and ongoing support
All V-TUF H-Class and M-Class extractors supported with UK-based spare parts and full servicing. HEPA cartridges and certified disposal bags held for ICRA-compliant use across the RUH estate and for heritage contractor use across Bath's World Heritage Site.
Dust generated by cutting, grinding and drilling on Bath construction and conservation sites must be controlled at source under COSHH 2002. In Bath, oolitic limestone is the dominant building material and H-Class extraction is the legal minimum across virtually all masonry operations. See COSHH Regulations guidance → and M-Class or H-Class extraction guidance → for a full breakdown.
