Keystone London - Plumbing & Heating

Keystone installed a new boiler for me last week. Sam the engineer responsible for it did a a great job. Work was done with minimal disruption despite being somewhat a tricky case. After having had a bad experience with two other companies who were not able to solve the problem, i can say was pleasantly surprised by how easily Sam and Dan managed and sorted my case. I highly recommend their services. Great professionals.

Really impressed with Keystone London. Daniel attended promptly on a Saturday morning to replace a failed radiator in a tenanted flat. The quote was clear, fair and honoured exactly as given. The work was carried out smoothly, with no drama, and everything was left tidy. Communication was excellent throughout. Reliable, professional and straightforward to deal with — highly recommended.

I am extremely impressed with the service I received from Keystone. Daniel and Lenny were not only highly knowledgeable but also well-organised and professional throughout the entire process. Their reliability and punctuality truly set them apart, and I am extremely grateful. I’ll be more than happy to have them return. Highly recommend! 🙏

Really pleased we went with Keystone London. I have rarely dealt with more communicative, helpful and professional people. When we were uncertain as to what we would like we were given very useful advice. Thanks to Dan for being so friendly with our excited dogs

Prompt response upon enquiry and competitive pricing, but not compromising quality of service. Boiler replacement enquiry made and scheduled video survey in a couple of hours, even at night, understanding my urgency. Quote and details of installation confirmed in less than an hour. Installation was done 2 days later, leaving a very satisfied customer, me. Daniel is a great guy, very positive attitude and enthusiastic. Had a chat with him casually before the work commenced. He is a very trustworthy engineer that I can rely on.
