Gareth, Lorenzo and Daniel are excellent to deal with and very efficient in their work. They fitted and service our boiler and recently replaced taps and a shower for us. This is an outstanding company to deal with because they are quick, clear in their quotations and always do the work well and clean up afterwards. Highly recommended.

I'm truly grateful to Gareth and Dan as always. I had a leak underneath my kitchen sink, whereby my washing machine hose pipe had split. Upon me phoning for help, Dan arrived at my home within 30 minutes. This company cannot be anymore trustworthy, helpful and kind. I honestly can't thank you enough. Highly recommend this company, always goes above and beyond. Thankyou, Louise.

Lorenzo and Dan couldn't have been more helpful with my Tado installation. Dan talked me through the hardware and answered all of my questions!

Rang Gareth with an issue, Daniel came out within a week, sorted problem. Daniel always on time, polite, friendly and knowledgeable. We have used this company for quite a few years now and would not go elsewhere. Make sure these guys are your first port of call. Thank you!

Gareth Williams' firm replaced my 20-year-old Valiant boiler with a new one. Two men and all done in a day. They worked hard, they were polite, and they cleaned up. I picked up the number from trusted traders, and I can say that they are a good firm, and I am really happy with their work.

Gareth Williams Heating Ltd did an excellent job removing our old, non-functional boiler and installing a new one. They guided us in selecting a reliable and efficient brand. I would highly recommend their services to any prospective clients.
