What Quelfire does
Quelfire is a privately held UK manufacturer of passive fire protection (firestopping) products, founded in 1977 and headquartered at a newly relocated facility in Wardle, Cheshire. The company designs, manufactures, and supplies intumescent-based firestopping solutions that seal service penetrations (pipes, ducts, cables) and linear gaps through fire-rated building assemblies, with products rated up to EI240 (4-hour) fire resistance and complementary acoustic performance. Its product portfolio includes the integrated QuelStop Firestopping System (fire collars, wraps, sleeves, batt, sealants, putty pads, and QF2 fire protection compound), the QuelCast cast-in fire collar for concrete frames, the QuelCoil continuous pipe wrap, the Intufoam linear gap seal, and supporting accessories, all tested as compatible systems to BS EN 1366-3 and BS EN 1366-4 at accredited laboratories. Quelfire maintains one of the largest UK tested-detail libraries (600+ scenarios), refreshed via monthly fire tests, and supports it with the award-winning QuelSelector V5 digital solution finder and BIM/NBS specification outputs.
Quelfire sells primarily to UK trade customers via a multi-channel model: direct account managers, a Shopify-based e-commerce storefront with next-day delivery and quote functionality, and trade merchant/reseller partnerships, supplemented by a credit account program for trade buyers. Pricing is quote-based rather than publicly disclosed. The go-to-market emphasizes early engagement at design stage with architects, main contractors, M&E contractors, firestopping specialists, concrete frame contractors, and merchants, reinforced by free CPD training, monthly public webinars, toolbox talks, and technical support responding within one working day. Compliance is anchored by ISO 9001, CE marking under the Construction Products Regulation, third-party certifications from Warringtonfire and UL Solutions, and Cyber Essentials.
Revenue derives from one-time product sales of firestopping components, bundled with value-added services (technical support, CPD/training, early engagement consultations) provided largely free of charge as specification-influencing activities. The customer base is diversified across residential developers (Bellway, Berkeley Group, St Edward Homes), healthcare (Royal United Hospitals Bath, New Care), education (Unite Students), government (Swindon Borough Council), and preferred-supplier relationships with major contractors including Willmott Dixon and McGoff Group, with recognition through multiple 2025 industry awards (ASFP Marketing Campaign and Digital Innovation of the Year, FSM Campaign of the Year, Willmott Dixon Goods Partner of the Year). Operations remain UK-only and ownership remains concentrated in the Wells family, with no disclosed external institutional investment.

Quelfire competitors and assessment
Company assessmentDirect peers
- FSi (Fire Stopping International): FSi manufactures tested firestopping products (Stopseal, PyroPro, PipeBloc) for service penetrations and linear gap seals, with comparable third-party certifications and a UK specification focus. Direct peer across product categories, customer segments (contractors, merchants), and regulatory positioning.
- Everbuild (Sika): Everbuild (owned by Sika) is a direct peer in fire-resistant sealants (e.g., Firefoam B1, intumescent acrylics) and firestopping accessories, sold through the same UK merchant channel. Highly comparable sealant product range and customer base.
- Sealmaster / Pyroplex: Pyroplex is a direct peer in intumescent firestopping products (fire collars, wraps, sealants) for service penetrations in the UK and Ireland. Comparable product categories, third-party certifications, and customer segments.
- Nullifire: Nullifire (part of Tremco CPG) is a direct competitor in intumescent firestopping and fire-resistant sealants for service penetrations. Highly comparable product portfolio (fire collars, sealants, batts, wraps) and overlapping UK specifier customer base targeting architects and main contractors.
Broad incumbents
- Rockwool: Rockwool is a broad incumbent in stone wool insulation and fire protection, including firestopping products for service penetrations (e.g., FirePro systems). Comparable as a tested-detail library provider with similar third-party certifications, but with much larger scale and broader building product portfolio.
- Promat: Promat (part of Etex Group) is a broad incumbent in passive fire protection offering fire-resistant boards, spray products, and firestopping solutions. Comparable as a wider portfolio passive fire player serving specifiers and contractors, but with significantly broader product scope beyond service penetration sealing.
- Sika UK: Sika is a broad incumbent in construction chemicals, sealants, and firestopping systems (including through Everbuild). Comparable as a fire sealant/sealing device competitor, but with vastly larger global scale and broader product portfolio.
- Hilti: Hilti is a broad incumbent in firestopping and construction fastening, offering CFS Firestop systems (boards, sealants, collars, wraps) for service penetrations with extensive tested detail libraries. Comparable target customers and product categories, with global specification reach and brand recognition.
- Würth (Firestop range): Würth offers a firestopping product range (sealants, collars, wraps) as part of its broader construction consumables portfolio. Comparable products for service penetration sealing, but primarily a merchant-channel multi-category player versus Quelfire's specialist focus.
- 3M Fire Protection: 3M (via the now-separated fire protection business) is a broad incumbent offering firestopping products including wraps, sealants, and tested systems with global reach. Comparable product range and tested detail philosophy, but vastly larger R&D and global distribution.
