Need a plumber in Northampton you can trust? THS Plumbing & Heating has served NN1–NN5 for over 25 years. From leaky taps in Abington to burst pipes in Kingsthorpe — we're your local experts.
With over 25 years serving Northampton, THS Plumbing & Heating has built a reputation as the most reliable plumber in Northampton. Our Gas Safe registered engineers (Reg. 517522) work across all NN postcodes — from NN1 Abington to NN5 Duston — delivering fast, clean, and fairly priced plumbing, every time.
We know Northampton homes inside out — from Victorian terraces in the town centre to new builds in Upton and Stanton Cross. That's why homeowners and landlords trust us for same-day repairs. Whether it's a dripping tap in Kingsthorpe, a burst pipe in Weston Favell, or a full boiler replacement in East Hunsbury, we're just one call away.
Book before 12pm and we'll aim to be with you the same day across NN1–NN5. No hidden call-out fees. Transparent quotes before we start. Our 283+ five-star Google reviews speak for themselves — from emergency leak fixes in Far Cotton to planned boiler upgrades in Bellinge.
Northampton's mix of historic semis in St James and Spinney Hill, modern apartments in Sixfields, and executive new builds in Upton demands a plumber who adapts to any system. THS engineers carry specialist tools for older lead pipes and the latest diagnostic tech for smart heating setups.
This versatility means we resolve radiator imbalances in Bellinge or pressure issues in Spinney Hill without guesswork or repeat visits. Landlords managing buy-to-lets across NN3 rely on our rapid turnaround — a single call schedules a full system health check, from boiler efficiency tests to pipe insulation assessments.
Homeowners in Far Cotton appreciate the same detail: we spot small corrosion risks before they become major leaks. Our vans carry 65% of common spares — thermostats, valves, pumps — so most jobs finish in one visit. For rarer parts, we source locally within hours, not days.
