As a MainPower customer you have the right to quality services, and a safe and reliable supply of electricity at all times.

You can access this service by contacting our Regulatory Manager in the following ways:

  • Phone us on 0800 TellMP (0800 835 567) or 03 311 8300

Our Regulatory Manager will record your complaint and take responsibility for ensuring your complaint is investigated thoroughly and promptly.

If we cannot resolve your complaint immediately, we will keep you informed on progress and aim to have your complaint resolved within a period of 20 days.

If we are unable to resolve your complaint to your satisfaction within 20 days, or an agreed extended period and we have reached ‘deadlock’, you may wish to contact the free, independent resolution service offered by Utilities Disputes Ltd. MainPower is a member of the this scheme.
