Woefully inadequate. It took British Gas three months and several attempts to 'set up' a direct debit (which, incidentally had been fully operational for many years). Repeated email complaints and requests, coupled with online chats failed to fix the error and I was forced into potential arrears with the prospect of being forcibly transferred to a more expensive prepayment option via their abuse of the legal system. Finally I had to work around their incompetence by settling the bills outside of their direct debit system. No operative had any understanding of the problems they themselves had caused, nor how to rectify them, and the promised telephone call from a 'specialist' never materialized. Repeatedly, emails were responded to with auto response promises of a detailed response from a manager, and again such detailed responses were not forthcoming. Complaints and problems were generally either not addressed, or were summarily dismissed by the operatives against whom the complaints were made. Today I have changed my gas supplier, and received from British Gas a patronizing public response PR exercise expressing their 'sadness' at losing me as customer and asking if they could do more, when a more honest question would be, could they have done less'. Undertrained or underqualified staff, aided and abetted or encouraged by feeble and cowardly management indicate that British Gas has a customer relations model unfit for purpose, which may go some way to explaining their loss of hundreds of thousands of customers over the past few years
