Hi Matthew, Further to my earlier review. I forgot to mention the contribution of Jason Graham who was instrumental in conveying my first impression of Simply Warmer as a credible & reliable company. Jason was my first point of contact with the company and, in the same manner as the engineer who completed the work, was also very personable and professional throughout our dealings, generating the necessary confidence required before a sale can follow without being in any way pushy. I believe that most of us buy from the person in the first instance and Jason proved that to be true. Peter 22, Stanley Park Litherland L21 9JT
