Your question
Will fitting a meter affect the electrical earthing in my property?
If we fit the meter inside your house, nothing we have done will change the continuity of the earthing or bonding of your electrical system. We will fit a permanent bonding cable around the meter and this must stay in place.
If we have fitted the meter outside your property and your electrical system used the water service pipe as an earth, there may be some effect. You have responsibility for the correct electrical earthing of your property. If you are concerned about this please contact a qualified electrician.
