Matt’s considerable charm is equally matched by the wealth of experience and thoroughness that he brings to the task of reviving flagging central heating systems. He worked unstintingly recently (8:30 a.m. to 5:30 p.m. with hardly a break) to restore our 22 radiator system that had all but given up the ghost. It is now working as quietly and as effectively as it did when it was first installed and I would unhesitatingly recommend his services to anyone with similar central heating problems.
