We recently had Matt and his team from Excelsior Heating Services install a Vaillant air source heat pump at our property, along with updating our entire heating system. From start to finish, their service was nothing short of excellent.Matt is exceptionally knowledgeable, guiding us through every step and ensuring we understood our options clearly. The team was punctual, courteous, and highly professional, taking great care to ensure minimal disruption to our home during installation.I highly recommend Matt and the Excelsior Heating Services team to anyone looking for reliable, high-quality heating solutions.

First rate service. I've been very happy with the team's work on the project and also the after care where we had a couple of problems that weren't due to their work.

Recently moved to the area and the previous owner of our Cottage recommended Matt to look after and service the oil boiler. Excellent! Punctual, friendly and did a great service job. Helped us to understand our heating.

I can’t rate this company highly enough. We were recommended to use them. Matt answered our calls promptly and arrived quickly and when he said he would. He is extremely knowledgeable and explained what he needed to do so that I understood. He repaired our system and serviced our boiler. It has taken us years to find a good plumber and I most definitely will use him moving forward.

Worked with Matt and the team for around 12 years at this point on everything from our big refurb to leaky taps. Nothing but good things to say - friendly, efficient, knowledgeable and reliable. Very much recommended 😊
