They guided us through the available heat pump grants UK and explained how the Boiler Upgrade Scheme heat pump works. The installation was smooth, and the system has made a noticeable difference in our heating bills. Id definitely recommend MASPER as MCS certified heat pump installers.

My Buckinghamshire house needed a new boiler, and Masper's crew was excellent! They had very competent and effective gas engineers. My new gas boiler was swiftly installed, and before they were done, they made sure everything was in perfect operating order. Additionally, they gave me an EICR certificate, which was really beneficial. Without a doubt, I will give them another call if I ever need heating or plumbing again!

Excellent job by Masper. They have replaced the wiring and connectors between the floors of our house. They opened up the panels, fixed everything and then closed all the openings and repainted everything so I would never have guessed where the job was done. They also fixed my boiler by replacing a pump affected by electrical issues. All done fast and with a great quality
