We use proper power flushing machines, not a garden hose and good intentions — the pressure and flow needed to properly clear a system requires the right tools.

What our clients say about our work
“⭐⭐⭐⭐⭐
After weeks of frustration with a leaking toilet that Rightio had supposedly fixed and checked twice, the leak was still there. In desperation, I searched Google and found JB7 Plumbing and Heating.
I rang on Tuesday 30th June at around 2:30pm and spoke to Sam. Luckily, they were able to book me in for 9:00am the following morning. John arrived promptly, quickly diagnosed the problem and explained everything clearly. The fault was a slow fill and a defective fill valve, which was causing the cistern to overflow and create the persistent leak that had been missed previously.
John was kind, friendly, highly experienced and a top-quality tradesman. Thanks to the excellent teamwork of Sam and Mary, communication throughout was outstanding, and the repair was completed by 2:00pm the same day. The work was clean, tidy, efficient and carried out to a very high standard.
The difference compared with the incorrect advice, diagnosis and repair I received elsewhere was remarkable.
What I'm most pleased about is that I've found a local plumber I can genuinely trust. JB7 Plumbing and Heating are transparent, friendly, helpful, provide superb customer service and deliver excellent quality workmanship. I wouldn't hesitate to recommend them and will, definitely use JB7 Plumbing and Heating company again.

I couldn't recommend them highly enough. The quality of their work and customer service was outstanding, and I'll definitely be using them again for any future plumbing needs.”

“Would definitely recommend. John and the team were able to come around late to help switch the heating system on following a house move, and then organised to visit later that week to install a new boiler. They were super friendly and helpful!”

“John from JB7 Plumbing came to my rescue after a complete toilet fiasco.
The week before, I had been ripped off by another plumber who left my toilet loose, poorly secured and leaking – significantly worse than the original broken flush I had paid him to repair.
I posted the job on Checkatrade and JB7 picked it up. John came round, quickly identified the problem, explained exactly what had gone wrong and talked me through the repair. Reassuringly, he stuck to his original quote with no unexpected extras.
Once the work was complete, he gave me a thorough handover and even told me to get back in touch if I experienced any further issues.
John was professional, friendly and courteous throughout.
The toilet is now rock solid, working perfectly and completely leak-free – and all for less than the original cowboy had charged me.
I genuinely cannot recommend JB7 Plumbing highly enough. Brilliant service from John from start to finish.
Thank you!”
