"Jason and his team recently replaced my Nan’s twenty-year-old oil fired central heating system. Right from the outset it was clear Jason is an expert and I had every confidence in his work, which was proven by the thoroughly professional installation he did. Jason replaced the oil tank, which involved making a new concrete base, buried the oil line under the patio and fitted an external Worcester-Bosch oil condensing boiler. Inside the property, Jason replaced every radiator and all of the pipework, there’s no visible damage to décor and all pipework is covered. Aside from it being clear the radiators, boiler and oil tank are new you’d have no idea so much work had just been undertaken. Dealing with Jason and seeing his work you can just tell you’re dealing with someone who does things properly. My Nan now has a completely new heating system that she’s really pleased with. Previously one room in the house was always colder, not anymore and each room now reaches the temperature it should. Jason thought of everything and I wouldn’t hesitate to use Jason in the future and cannot recommend him enough."
