About Phillip
Phillip Halliday is the founder and sole trader behind CH4 Gas Plumbing & Installation — a name built on more than two and a half decades of honest, skilled work across Northern Ireland.
Phillip completed a formal 3½ year plumbing apprenticeship, earning a thorough grounding in every aspect of the trade before working independently. That foundation, combined with over 25 years of hands-on experience, means you're getting one of the most knowledgeable plumbers in the area.
Based in Carrickfergus, Phillip primarily serves the local area — delivering faster response times, genuine familiarity with local housing stock, and the kind of personal service you won't get from a larger company.
Every job is treated the same: upfront pricing, clean workmanship, and no surprise bills. Phillip's reputation has been built one satisfied customer at a time.
A full 3½ year plumbing apprenticeship — properly trained from day one, not just self-taught.
Legally registered to work on gas appliances and pipework. Reg. No. 229117 — verifiable at GasSafeRegister.co.uk
Over a quarter century of real-world plumbing and gas work. There are very few problems Phillip hasn't solved before.
Carrickfergus is home. Phillip knows the area, the properties, and the people — and that makes a real difference.
