Detailed Timeline
🇬🇧 Where the UK Stands — March 2026
No masonry heater association exists
EN 15544 adopted as BS EN 15544:2023 but has zero regulatory function
No calculation-based compliance pathway for site-built heaters
No professional qualification or training programme
No government subsidies for masonry heater installation
Defra 2026 consultation does not mention masonry heaters
A handful of builders operate without formal recognition or association
At least 8 companies actively supply, build, or install masonry heaters — Ceramic Stove Co., Eccostove, Cornish Masonry Stoves, StoveMason, Gondwana Green Heat, Beacon Stoves, Moslin Stoves, Tulikivi UK dealers
One HETAS-registered masonry heater builder exists (StoveMason, Scotland) — building to BS EN 15544, member of both MHA and Austrian KOV
BS EN 15544:2023 is already a British Standard — the legal foundation exists
HETAS infrastructure exists — could certify masonry heater builders like it certifies stove installers
UK-manufactured masonry heaters exist — Eccostove (silicon carbide, Studley) and Cornish Masonry Stoves (porcelain, Bodmin) both tested to EN 15250
The French precedent is the proof. France had no masonry heater culture in 2013. Thirteen years later, AFPMA has achieved government recognition, tax code inclusion, professional certification, subsidies, its own research laboratory, custom calculation software, and ~1,000 installations per year. The UK has all the same building blocks — BS EN 15544, a HETAS framework, individual skilled builders, UK manufacturers — but lacks the association to connect them. Everything France achieved started with one thing: artisans organising.
