Bit of free advice.....don't go there unless it's a last resort. Treat their field staff like excrement unless you work in the office. Loads of people out for themselves loads of backstabbers and quite a few who are winging it. The operations manager of the gas is a painter and decorator ffs!!! And watch what you say to people most are related to someone, somewhere in the company. What are you going for service and breakdown or installs? Plus you'll pay for the slightest bit of damage for anything and they'll beleive the tenant if they say you've damage something, so you'll be paying.
