Electricity meters do not tend to make any noise. If you are hearing any humming, ticking or other noises, contact your distributors faults line and they will arrange for someone to attend your property to inspect your meter. If it found that your meter is faulty, it will need to be replaced.
Get in touch with your Distributor, who will attend your property to take a look.
