What should you expect from your energy supplier ?

Power and gas are supplied by companies called suppliers who buy energy on the market and pay network owners to bring it to your meter.
Your first contact will most probably happen on the phone to set up a contract, while your customer service will assist you all along your time as their customer. Your supplier will mail or email you power and gas bills at each term. The supplier may also order your meter to be shut if your bills remain unpaid.

When choosing an energy supplier, you should enquire as to prices and rates, billing options, fees and charges, and customer service quality. If you are unsatisfied with your energy supplier (in terms of billing or customer care, or if you want exclusively renewable energy, for example), you may want to switch to another electricity and/or gas supplier. This requires looking into what offers are available on the energy market and choosing the one that best fits you and your consumption.
