The initial installation experience in Scotland was a nightmare with shoddy workmanship which was only resolved when I with held payment. Now two years later my annual service is now months overdue. I have phoned and been informed that the service engineer for Scotland has been on long term sick leave and service engineers will be deployed from England but no dates given. Disappointed that this company which were sold to us as professional and had customer care at the forefront of their operation- a) have only one service engineer for Scotland and b)when I phoned to enquire (twice in July/August) when I would have my boiler serviced I was informed that they have been unable to recruit a replacement engineer in Scotland and would dispatch service engineers from England but could not give a date for this. Avoid this company
