Meter Asset Provisions (MAP) charges

This is the cost of the electricity metering on site from the company that owns it, known as the Meter Asset Provider, or MAP.

If a meter wasn’t purchased upfront, or being paid for in any existing Meter Operator (MOP) contracts, then the MAP will charge a monthly rental for the meter. This charge from the metering agent is sent via your customer’s energy supplier, and under most contracts would then be passed on to their customer bill.

Energy suppliers have previously absorbed this cost to avoid passing it on to their customers. However, from 1 April 2021 they will now be applying these charges to customer bills. The amount charged will be based on the invoice received for the customer’s MAPs, and so the exact charge won’t be known until you receive the invoice. For the majority of customers these charges are less than £10 per MPAN per month.

Site Visit charges for manual meter reads

This relates to the cost of the Data Collector (DC) sending an agent out to the meter location to try and arrange for the consumption data from the meter to be downloaded, so it can be used to accurately bill.

Whilst all HH meters should have a method of communicating with it remotely (i.e. a land line or a SIM card), this is not always the case. Sometimes the cost of installing a line is unappealing, or sometimes they stop working. In these cases, the DC have an obligation to try and retrieve consumption data from the meter via weekly manual reads. Those manual reads are much costlier than using the remote communications and regardless of whether an agent was able to successfully download the data or not, any attempt to get to site is a cost to the DC, which will be passed on.

Previously when this happened, suppliers would add a fixed monthly premium to the standard monthly Data Collection charges on a customer’s invoice, to cover the additional work of their DC. However, this method meant that everyone was charged the same regardless of how many site visits they’d needed or the actual cost from their DC. Suppliers want this to be more fair, and so moving forward suppliers will apply this as a separate charge to HH invoices based on any additional costs for each site visit that we’re informed of by their DC.
