Brilliant initial installation, very professional & offers peace of mind with 10 Year warranty. Just had my 1st year annual service, received an email reminder on the Wednesday, booked in for the following Tuesday (as requested by myself) & service documentation provided via email whilst technician was on site. Couldn’t recommend Ian & the team highly enough. Great work Smart Plumbing.

Ian and Tom did a fantastic job on our full boiler fitting..a full day of hard work along with great customer care and understanding. They both went out of their way to ensure the work was to the highest standard and above and beyond to source any equipment needed. The price I was quoted I paid and at a fantastic rate. Thankyou so much to both Ian and Tom. To any new customers ...I highly recommend Smart Plumbing as the team to choose for your next boiler!

Smart Plumbing have been great to deal with. Having had my boiler installed by them a year ago, it's recently had its first year service done by them also. I've found them to be very reliable, efficient and trustworthy, which I feel are all important qualities these days. I wouldn't hesitate to recommend them. Excellent!

We contacted Ian after a tenant reported a non-working boiler late on a Friday. Communication was fantastic, the boiler was replaced on the Sunday and all warranty paperwork emailed to our office the next day! Not used Smart Plumbing before this job but will definitely be adding Ian to our contractors list!
