Declan is very polite and helpful

Declan is very polite and helpful, reasonably priced and turns up when he says he will. We used him at our old home to urgently inspect a 20+ year old boiler, and has serviced a new boiler within our new home.

Will continue to use in the future!

Reliable and professional

From our first conversation to the end of the work, Declan was professional and reliable. The new boiler was fitted on the scheduled day and his work was of a very high standard. I would absolutely recommend him to anyone looking for an honest and reliable tradesman.

Declan stepped in to finish our bathroom refit and sort out the towel rail for us. He sorted the issues with tiling and has done a great job for us. Highly recommend

Replacement of bygone era 600 x 2000 radiator

Fantastic! Declan completed the replacement of a very old 600mm x 2000mm radiator, which was connected to a dated boiler system. This resulted in some connection anomalies, which Declan resolved with precision. From confirming the upgrade via the online platform, to payment on the completion of the upgrade, the whole process was seamless!

Boiler service and repair

What a fantastic experience. Declin came on time carried out the work with no fuss or mess, he even had to put up with my noisy jack russells.
I would highly recommend him very easy and polite.

Annual Gas Boiler Review

Declan has carried out an annual service on our gas boiler since installing it new in 2020 following an inspection of our 45 year old gas boiler’s failure. Always pleasant and tidy.

New hot water system

Excellent work from start to finish. Declan sourced a pressurised hot water tank and installed it along with new pipework. Also fitted a new shower and taps. Pressure is now fantastic. Declan knows his stuff, is reliable, courteous, tidy and always keeps the customer updated. Highly recommended.
