Moving House with Mercury - FAQS


Moving is simple online via the My Account section of our website - take a look at our latest move offers when you move online. If you'd rather get in touch via a phone call, you can contact us on 0800 10 18 10.
Business customers please call us on 0800 20 18 20 to move.


To have a more accurate first bill in your new property you can call us with a meter reading once you move in. However this is not required if you have a smart meter installed on the property.

If you are not already a Mercury customer then join Mercury and become a part of our family.


We recommend you give us 5 working days notice before moving house, so we can make your move as seamless as possible.


Yes Mercury can supply both electricity and mains or reticulated gas. However we do not supply bottled LPG.


No, Mercury will not charge you any fees to move your power to a new property. In fact, check out our latest move offers here.


To ensure that we have the right address and can accurately locate your property, it helps to have your meter number or ICP number handy (which can both be found on your meter box). If you are moving into a flat or unit with multiple properties close by, these details will ensure we select the right property.


This is the unique number that identifies your address for energy supply. You can find your ICP number under 'ICP Identifier' on page 2 of your Mercury bill.

It will look something like this:



As long as the power has not been disconnected at your new address, power will be available to use.  Make sure you’ve notified us of your move date and details at your new property before you move. This will help us to ensure that your power is ready to go at your new property by the time you move in.


We will not disconnect the power on the day you move out of the property. Power will be left connected for the next resident to move in. We’ll need a final reading before you vacate the property to ensure that you are only billed for your usage up until the time you vacate the property. If the property remains vacant for a long period of time, then we will likely disconnect the supply.


Rates are based on the location of your property so depending on where you are moving to you may see a change in your bill.


This depends on where you are moving to. In some cases you can take your contract with you to your new property. In other cases your rates may need to be revised and you will be moved off the contract without an early termination fee. Please give our team a call to chat through your situation and be sure to check out our latest move offers here.


Give Mercury a call on 0800 10 18 10 with your meter number or ICP number (which can both be found on your meter box) and we can help you sort this. The property may have been vacant for a period of time and the last provider may have disconnected the supply because of this. Fees may apply to reconnect your supply.


Yes – give us a call on 0800 10 18 10 once you know your move in date and we can carry your account across to the new property. If you have already moved in, give us a call and we will switch your supply across to Mercury.  Take a look at our latest move offers here.


The move out date and final reading should be for the last day that you wish to use power and have access to the property before handover.


If you have a smart meter installed at your property, we will organise a final reading based on the move out dates you have given us. Otherwise your final reading will be estimated unless you supply us with a final meter read for the property. 


You can give us a call on 0800 10 18 10 with a reading, or we can organise for someone to come and take a final meter reading for you (fees apply).
