As one of the UK’s most trusted MOPs, we are experts in the installation and operation of electricity meters. We can also consolidate your metering activity with high-quality data, enabling you to take full control of your consumption and reduce operational costs.


Accredited meter operators

As a fully Elexon-accredited non-half hourly (NHH) and half-hourly (HH) meter operator (MOPs), we are one of the leading independent electricity metering service providers to the UK industrial, commercial and public sectors. 

By law, customers with half hourly electricity supplied meters (sites with a maximum demand of over 100kW) must enter into a meter operator agreement, or MOP contract. As a meter operator, irrespective of your requirements or portfolio size, we can provide bespoke electricity metering services in the supply, installation, maintenance and operation of your meters, along with an unrivalled customer service.

Data collector and data aggregator

We are one of the few meter operator providers (MOP) in the UK to be a data collector and data aggregator (DCDA) as well. Our fully integrated service combines MOP and DCDA solutions. Managing the complete metering, collection and aggregation process in-house allows us to maximise efficiency and accuracy. This also minimises the billing risk arising from data issues within the supply chain.

Frequently asked questions about Meter Operator contracts

A Meter Operator Contract covers the installation, operation and management of HH electricity meters. A MOP customer contract is required by law for businesses with HH meters with 100kW plus consumption.

Yes. A meter operator contract is no longer part of the standard supply agreement with your energy supplier, so you are therefore entitled to choose your own HH MOP based on your specific requirements. There are significant advantages available by doing this.  If you do not appoint a HH meter operator independently, then your energy supplier will likely appoint one on your behalf, usually their preferred HH MOP.

A MOP contract is a separate agreement that is independent from an electricity supply agreement, so you will be invoiced directly by your HH meter operator for any service charges outlined in the contract. If you have been appointed a HH MOP by your energy supplier, additional costs may be passed through on your supply contract.

If you decide to look for a new meter operator agreement, you should first decide which HH MOP is the best for you based on your requirements. The best way to do this is to discuss your needs with the HH MOP directly. Once you have agreed a contract, a meter installation date or contract start date will have to be coordinated with the energy supplier. If you are public sector company, you can tender for your HH MOP through a framework agreement.

You are free to choose different companies for HH MOP and DCDA services, however it is highly advisable to combine this solution in order to reduce issues within the supply chain, improving the efficiency and accuracy of your data provision. SMS Plc is one of the few UK providers that offer this integrated metering and data service completely under one roof.
