What Mi-Flues does
Mi-Flues Ltd is a UK private limited company (Company No. 3277400) headquartered at Taymin Business Park, Blackpool, Lancashire, that manufactures and distributes chimney, flue, and fireplace products under a portfolio of own brands including Mi-FLEX (flexible liners), Mi-Beam (composite beams), Mi-Flash, Mi-Cowl, Mi-Fire, and Mi-Decking, alongside distributed third-party brands such as TWPro, KC Economy, Sflue, Commercial Flue, Burgerhout, Lacunza, and Vlaze. The company operates 34 trade counters and 4 distribution centers across England, supported by 7 regional sales managers covering the North West, North East, East, Central, South East, South Wales, and South West, plus an e-commerce platform at mi-flues.com serving both trade and domestic customers.
The business manufactures flexible liners, twin wall flues, single wall flues, commercial flues, connecting pipes, cowls, flashings, installation parts, after-care parts, stoves, fireplaces, and an expanding range of outdoor living products including kamado grills, pizza ovens, fire pits, and wood wool firelighters. Recent launches of Mi-Beam composite beams and the Mi-Decking sub-brand indicate active SKU and category extension beyond the original chimney core.
Mi-Flues generates revenue through a multi-channel trade and retail model: trade installers purchase via counter visits or login-based online pricing accounts with regional account management, while domestic consumers buy through the e-commerce site and counters. The company appears family-led, with Andy Zakrzewski as Managing Director and Taylor Zakrzewski as Manufacturing Manager, and operates exclusively within the UK market. No international expansion, AI/ML capability, or enterprise customer concentration is evident in the source material.

Mi-Flues competitors and assessment
Company assessmentDirect peers
- Premier Flues: UK supplier of twin wall flue systems, flexible liners, and chimney cowls to installers and merchants. Direct overlap with Mi-Flues' core flue product categories and trade customer base.
- BPC Ventilation: UK distributor of ventilation, flue, and HVAC products serving trade and installer customers. Comparable as a broadline competitor in flue distribution, twin wall systems, and ventilation ducting.
- Eurostove: UK distributor of European stove brands including Heta, Westfire, and Dik Guerts. Comparable to Mi-Flues' stove distribution and dealer-supply activities, with overlapping trade customer base in England.
- ACR Stoves: UK manufacturer of multifuel and woodburning stoves sold through dealer networks. Directly comparable to Mi-Flues' Mi-Fire and showroom stove categories, serving installers via trade channels.
- Trade Price Flues: UK trade-focused online retailer of flue systems, chimney products, and stove installation accessories. Directly comparable to Mi-Flues' e-commerce and trade pricing model across twin wall flue, liners, and cowls.
- Selkie (Flexible Flue Liners): UK-based manufacturer and supplier of flexible chimney flue liners. Directly comparable to Mi-Flues' Mi-FLEX range, competing on stainless steel flexible liners and chimney lining accessories for the trade and installer market.
- Burgerhout (Convesa): European manufacturer of polypropylene and stainless flue systems including TwinFlex, TwinSafe, and MultiLine ranges. Already distributed by Mi-Flues in the UK, but a direct competitor at brand level across gas boiler flue and ventilation categories.
Emerging players
- FlueCube (Twin Wall Flue Systems): UK specialist in twin wall insulated flue systems and chimney products for installers. Niche competitor to Mi-Flues' TWPro and twin wall categories with partial geographic and SKU overlap.
Broad incumbents
- Worcester Bosch (heating): Major UK boiler and heating appliance manufacturer. Adjacent competitor in the residential heating ecosystem, representing both a buyer of flue components (via specifier relationships) and a strategic threat as heat pumps displace traditional flue-dependent heating.
- Dunster House: UK manufacturer and retailer of garden buildings, log cabins, and outdoor living products including pizza ovens and outdoor heating. Comparable to Mi-Flues' Outdoor Living category expansion (Kamado, pizza ovens, fire pits) at the consumer end.
