    "I couldn't ask for a better person to install my new Bosch combi boiler. The installer was incredibly reliable and professional from start to finish. The workmanship was first-class quality, and he went above and beyond with extra touches to ensure everything was perfect from every angle and aspect. Thank you very much for an outstanding job!"

    "My central heating had not been working for some years. Tony patiently considered and inspected every aspect of the system functionality, graciously answered questions, calmly explained all he needed to do and why, in order for the new boiler to work at its best, as he progressively worked and identified various system issues. Tony was totally focussed on making sure everything worked and his insightful solutions resulted in every radiator in the house heating up from top to bottom. Tony completed the necessary paperwork for me to receive a 10 year boiler repair guarantee from the manufacturer. Tony also replaced my bathroom sink taps and was flexible, as he also kindly completed an additional unexpected fix. I am totally happy with all the results. I found Tony to be patient, calmly professional, straightforward, honest, kind, very hard working, totally focussed on giving the customer his best, and totally trustworthy. I highly recommend Tony."

    "After doing a lot of research into what plumber to choose and what company I decided to contact Tony. he initially came round to look at my boiler, and spent time diagnosing and looking at it for me with no charge.he then made recommendations as to what to do. I ended up needing to replace the boiler. Tony supplied and installed a new boiler system as well as doing some additional work. he was very punctual,tidy,polite and happy to awnser all my questions. his work was carried out to a very high standard. 2 days later he gave me a courtesy call just to make sure everything is okay and If I had any further questions. I would recommend Tony to anyone and everyone who needs any type of plumbing work done. 5 stars all the way !! Many thanks AGN PLUMMING AND GAS HEATING"

    "Tony has helped us over multiple callouts, for a variety of issues, from boiler work to the latest problem, which was a blocked sink. He is always punctual, extremely friendly and always explains what needs to be done beforehand, and what he's doing during the work itself. He has also helped us resolve issues without a callout, via the phone, which has saved us money in the past. Having such a trusted plumber makes it very easy to recommend him, as Tony is the epitome of what you want from an expert when you are in need."
