They're also members of the Chartered Institute of Plumbing and Heating Engineering.

How we chose the top 5 plumbers in Northampton
Every business on this page earned its place through independent research. We look at where companies rank organically on Google, the volume and quality of their reviews, ratings and verification across platforms like Checkatrade, Which? Trusted Traders and TrustATrader, relevant trade accreditations, and the kind of word-of-mouth and social proof that's hard to fake. No business can pay to appear in this organic Top 5 — the list is earned and reviewed regularly.
If you're comparing plumbers in Northampton, any of the five above is a sound starting point. We'd still recommend getting more than one quote and confirming current availability and accreditations directly with the business before you book.
Finding a good plumber in Northampton
Northampton has a healthy mix of independent tradespeople and small local firms, and as anywhere, quality varies. Every business on this page earned its place through independent research — online reputation, verified reviews, local trading evidence and professional credentials — and none of them paid to appear.
For any gas or boiler work, always check a plumber is Gas Safe registered — it's a legal requirement, not just a quality mark. For general plumbing, look for verifiable reviews on Google, Checkatrade or Which? Trusted Traders rather than a company's own website alone, and consider an approved contractor on the WaterSafe scheme.
