I moved from boost to British Gas purely because boost only offer a "pay as you go" option. it took 2 months i was advised 2 weeks initially. i had to call weekly to progress the move and chase when an engineer would be able to swap the meters. i got passed from department to department. having to repeat my requirements again and again awful company to deal with. promised call backs were never received. the staff were ill equipped to deal with this simple move the call times were horrendous and i spent over 30 minutes on every call i had to make to them and the engineer still didn't come out on the designated date and time totally incompetent
