Plumbers & heating engineers
Mostly sourced from the Guernsey Building Trade Employers Association (GBTEA) member directory.
740 Guernsey planning applications now awaiting a decision or recently consented involve this kind of work — an estimated £79,816,000–£127,424,000 of it. A permission is not a building and plenty lapse unbuilt, so read it as consented work rather than work in progress. See what and where.
Danny Hill Plumbing Ltd
GBTEA member, Plumbing & Heating Engineers category.
Datum Ltd
GBTEA member, Plumbing & Heating Engineers category. Email domain (datumph@gmail.com) suggests trading style 'Datum P&H'; unconfirmed.
Dave Brook Ltd
GBTEA member, Plumbing & Heating Engineers category. GBTEA lists no separate website field, though its contact email domain (davebrookltd.co.uk) implies one exists — not independently confirmed live.
Griffin Plumbing and Heating
GBTEA member, Plumbing & Heating Engineers category.
Heat Source Plumbing
GBTEA member, Plumbing & Heating Engineers category.
Infinity Eco Installations
GBTEA member, Plumbing & Heating Engineers category — renewable/eco heating installations (heat pumps etc). Contact email domain (ecoinstallations@infinity.gg) matches the Infinity Group/Infinity Construction Ltd (www.infinity.gg) already listed in builders-developers.json as a builder-developer — appears to be that group's renewables-installation arm, not independently corroborated further.
Mechanical & Electrical Contractors Ltd
GBTEA member in both the Plumbing & Heating Engineers and Electrical Contractors categories — a genuine dual-trade M&E contractor. Also listed in electricians.json; same firm, not a duplicate.
Ozanne Plumbing Ltd
GBTEA member, Plumbing & Heating Engineers category. Shares the surname 'Ozanne' with Duquemin & Ozanne (CI) Ltd (also in this file) but no evidence found linking the two businesses — treat as unrelated pending verification.
Phase Mechanical Contractors Ltd
GBTEA member, Plumbing & Heating Engineers category — mechanical/heating engineering arm of the Phase group. Same phase.gg contact (enquiries@phase.gg) and phone number as Phase Electrical Contractors Limited in electricians.json — one group, two trade divisions.
Priaulx West Ltd
GBTEA member, Plumbing & Heating Engineers category.
Rang's Plumbing & Heating Services Ltd
GBTEA member, Plumbing & Heating Engineers category.
Style Plumbing & Heating Ltd
GBTEA member, Plumbing & Heating Engineers category.
Duquemin & Ozanne (CI) Ltd
GBTEA member, Heating Consultants, Design & Supply category; also a Guernsey Chamber of Commerce member. Local supplier/consultant for plumbing, heating, bathrooms and renewable-energy products (decades of trading in the Bailiwick) rather than a direct installation contractor — listed here as heating-adjacent given the task's plumbing/heating scope.
A1 Gas Plumbing & Heating Ltd
Gas Safe registered heating & gas engineer (contact: Shaun); combi/heat-only boiler installation, radiators, underfloor heating, LPG, landlord gas-safety certificates. Found via web search/business directory, not a GBTEA member — direct fetch of a1gasltd.co.uk failed during research (DNS error), so treat the live-site detail as unconfirmed even though the business itself is well corroborated across directories.
All Aspects Plumbing & Heating Ltd
St Sampson's-based plumbing & heating firm (contact: Jed); approved Saniflo technician. Found via web search/BookLocal.gg listing, not a GBTEA member. Website inferred from contact email domain (Jed@allaspects.gg), not independently loaded.
Guernsey Electricity Limited
The island's statutory electricity generation/distribution utility, but its Contracting division is separately a GBTEA member in the Plumbing & Heating Engineers category (contracting@electricity.gg) and directly employs plumbers as well as electricians, offering installation and repair work to the public (site copy: 'Guernsey's reliable electricians and plumbers... our team'; NICEIC/OFTEC/Guild of Master Craftsmen credentials cited). Same firm also listed in electricians.json for its electrical-contracting role — the two entries describe one company's two trade divisions, not a duplicate.
