Fantastic service!! Had an issue with my boiler, the part was ordered and fitted as quickly as it could be. There turned out to be a further issue and this was rectified on the spot. Price’s were extremely reasonable.
I would highly recommend this company, very genuine, friendly and get the job done. Thank you Graham and Mark 🙂
Have just had my central heating system replaced by these lovely lads. Professional, knowledgeable, trustworthy, clean and tidy and nothing was too much trouble. The job was completed in 2 days. I couldn’t be more pleased so thank you Mark, Graeme and Glen for a brilliant job.
I recently had the pleasure of using Lock & Lindfield for a plumbing job at my house, and I couldn’t be more satisfied with the service I received. From start to finish, my experience was nothing short of exceptional and I wouldn’t hesitate in recommending them to my friends and family. A big shout-out to Mark, he was especially helpful!
Thank you
Prompt with our appointment time. Very knowledgeable and worked out immediately what needed to be fixed. Explained clearly what the solution would be and presented a quotation that was accurate with no extra charges on completion. Always felt comfortable and a trustworthy company to deal with.
I have used Lock & Linfield for many years both for personal works and business works. They help maintain our over 200+ managed properties @ Open House. Anything from broken flushers, drips, and leaks all the way through to full boiler and central heating installations. Always reliable, polite, punctual and fairly priced.
Great company! Use them for all my jobs whether big or small. Neat tidy and great work. Lovely guys and would and do recommend to friends and family
Very efficient, clean service, I use every year and wouldn’t use anyone else.
Very pleased with the work 😊

Mark, Graeme and their very bright apprentice Ryan, were highly professional, completing our new boiler installation with modifications to our heating and hot water system rapidly and efficiently. The installation and pipe runs are now much tidier than before. They gave us a thorough briefing on the new controls which can now be accessed via an app when we’re away from home. As to cleanliness, our carpets were covered in a protective film leaving them spotless and they left the house neat and tidy after each days work. Overall we very highly recommend them.Posted on Google Kellythetraveller DTrustindex verifies that the original source of the review is Google.

I recently had a new boiler installed and my central heating system extended, and I couldn’t be happier with the service. The company did an excellent job from start to finish. Graeme and Mark carried out the work, and despite the job involving quite a bit of disruption, they made the whole process easy and stress-free. They were friendly, knowledgeable, and highly professional throughout. They also took great care in my flat and left everything in great condition after giving the place a thorough tidy at the end of the job. I’m really pleased with the results and wouldn’t hesitate to recommend them to anyone looking for reliable, high-quality heating work. Highly recommended!Posted on Google Brendan GraafTrustindex verifies that the original source of the review is Google. Graeme & Mark provided an all around excellent service with our new boiler installationPosted on Google stephen rosenthalTrustindex verifies that the original source of the review is Google. Thanks to Graeme, Mark & Adrian for replacing our old boiler with a smart new combi boiler and adding another radiator. From start to finish we are very happy with the quality of the work and the care they took over our property, they flushed the system and that along with the new boiler has made a big difference . I would use this company again and recommend it if you are looking for a quality plumbing and heating company.Posted on Google Lauren SmithTrustindex verifies that the original source of the review is Google. Would 100% recommend!! Had a boiler service and a pretty serious fault was found that meant the boiler had to be turned off! (Not ideal with a 1 and 3 year old). Graeme & Mark sent a quote that same day and were back to fix the problem within 1 day!! So quick, tidy and knowledgable! Thank you so so much!! :) Will defiantly use Graeme & Mark again in the future!Posted on Google Emily JaneTrustindex verifies that the original source of the review is Google. Mark, Graeme & Ryan simply amazing from start to finish! Replacing our very old back boiler system, and radiators, they made it seem effortless and left the house cleaner than when they started! Couldn't recommend more, always smiling despite the challenge they had with our property, quick, efficient and organised! Can't thank you enough will be coming to you from now on. Thank you again, for making a stressful job such plain sailing for us! ☺️Posted on Google Mandy FraserTrustindex verifies that the original source of the review is Google. It was an absolute pleasure doing business with these guys. Efficient, quick, professional, personable. From initial site visit/quote to completion within a week. 45 year old boiler stripped out and replaced with a new efficient boiler/heating system with all works completed within 2 days at a reasonable cost. Would highly recommend.
