    My go to choice of plumbers/heating engineers in the Lincoln area

    Posted 4 days ago

    Once again excellent work carried out by the team at No1 British Boilers. They are always on time, always ready to explain what they are doing and why and are very cost efficient. They are defiantly the go to heating engineers. I would highly recommend you talk to them first if you have any plumbing/heating issues to deal with.

    New boiler

    Posted 22 November 2025

    Lee was very fast on coming to quote us for a new boiler. Jack was very professional and knowledgeable, he explained what he was going to do and kept me informed through the process. Once new boiler and hive was installed Jack talked me through how to program and use. Would highly recommend. Thank you Sidney and Michelle

    Amazing company

    Posted 21 November 2025

    Highly recommend!!! Enquired for a quote as we had a 22 year old boiler! Had a call within a few hours of enquiry offering to come out same day to quote! The quote was over £400 cheaper than any others we had received and an offer of a better boiler with longer guarantee! We were booked in so quickly for the work to be done! The team were amazing, high standard of work and very respectful of the house, and even stayed late one night to make sure we got our heating back in good time! Communication is great from Lee and we’ve even signed up to their boiler aftercare plan for peace of mind!
