No aftercare service at all despite nemerous calls and promises! Don't bother with these guys as once the work is done they simply don't care! Just clearly a moneymaking scheme with no customer care at all. My parents who are both in their mid 80s have no control of the heating and its coming on all different times of the day and night and some times impossible to turn off for a few hours! They have been left stressed and in tears! I have told them this and still nothing is done to resolve their bodge installation! If you want aftercare don't bother with Britain Energy!!
