THS Plumbing & Heating Northampton
Northampton & Northamptonshire · Emergency Plumbing, Boilers & Heating

THS are the standout local plumbing and heating business in Northampton. Established in 2000 and Gas Safe registered (no. 517522), they've built one of the strongest review profiles in the area — their website cites 4.9 out of 5 from 283 Google reviews, which is a remarkable signal for a local trades business. Their website targets emergency plumbing, boiler repair, boiler servicing and central heating across Northampton and surrounding areas including Abington, Kingsthorpe, Duston, Wellingborough, Kettering and Daventry.

Wentworth and Jeffries Plumbing & Heating
Northampton & Northamptonshire · Plumbing, Heating & Gas

Wentworth and Jeffries are a well-rounded Northampton plumbing and heating company with a broad service offer and solid independent credentials. Their website directly targets plumber in Northampton and covers boiler installations, servicing and repairs, central heating, bathroom fitting, gas and heating engineer work, and emergency plumbing. What sets them apart is the combination of Which? Trusted Trader membership and Checkatrade accreditation — both platforms apply their own vetting, so carrying both is a meaningful trust indicator. A family-run feel with a professional finish.

Engas Plumber Northampton
Northampton & Northamptonshire · Gas, Heating & Plumbing

Engas are one of the longest-established Gas Safe registered engineers in Northamptonshire, having traded since 1973. That kind of longevity in a competitive local market is a genuine indicator of consistent quality — businesses don't last 50 years on one-off jobs. Their service offer is particularly strong on the gas and heating side: boiler repairs and installations, gas fire repairs, cooker repairs, water heaters, warm air systems, powerflushing, landlord gas safety certificates and central heating repairs, alongside general plumbing. They're also members of the Chartered Institute of Plumbing and Heating Engineering. The website is functional rather than flashy, but the depth of expertise and institutional trust signals more than compensate.

Steele's Plumbing & Heating
Northampton & surrounds · Domestic & Commercial Plumbing

Steele's are a family-run plumbing and heating business based in Northampton with over 10 years' local experience. They cover domestic and commercial plumbing across Northampton and within a 20–30 mile radius, and carry Checkatrade accreditation as an independent quality signal. Third-party review data shows a rating of 4.89 out of 5 from 47 TrustATrader reviews — a smaller volume than THS, but a consistently high score. Their positioning emphasises reliability and being a trusted local team rather than a large or impersonal operation, which tends to resonate well for the kind of repeat residential plumbing work most homeowners need.

JD Plumbing & Heating
Northampton · Plumbing, Boilers & Central Heating

JD Plumbing & Heating bring 20 years of Northampton plumbing and heating experience to the table, with Gas Safe registration and a clear service focus across domestic plumbing, boilers and central heating. Their website references major boiler brands including Vaillant, Ideal and Worcester, which signals a business comfortable with the full range of residential heating work rather than just basic plumbing. A straightforward, no-fuss local business with genuine local roots and the experience to back it up — a solid fifth-place choice for Northampton homeowners.

Finding a Good Plumber in Northampton

Northampton has a strong pool of independent local plumbers and small heating firms — but quality and credentials vary considerably. The businesses on this list have been selected based on their online reputation, verified reviews, local trading evidence and professional credentials. None of them paid to appear here.

When looking for a plumber in Northampton, always check Gas Safe registration if the work involves a boiler or any gas appliance — this is a legal requirement, not just a quality marker. You can verify any engineer's registration at the official Gas Safe Register website. For general plumbing work, verifiable reviews on platforms like Google, Checkatrade or Which? Trusted Traders are a more reliable guide than a company's own website testimonials.
