H2 Property Services provided me am excellent service when my combi boiler was losing pressure. From my initial phone call to their office, they understood the issue I was trying to describe and were able to arrange for a engineer to come the very next morning. When Dave arrived he was polite and professional. He worked thoroughly to find the cause (a small leak). He put in place a temporary fix and identified the part that needed replacing. H2 then followed up, obtaining the part (specific to the make and model of my boiler). I rebooked H2 to return, again Dave was here the next day. I'm very happy with the service I received, and that I now have a go to plumber I'll use in future. Delighted. Thank you H2.
