Do I need a MOP agreement?

By law, business consumers with half-hourly electricity supplied meters (sites with a maximum demand of over 100kW) must enter into a meter operator agreement, or MOP contract. You are free to choose any accredited MOP to operate your meters, no matter who supplies your energy.

Our customers choose us because of our dedicated support, industry experience, and end-to-end energy service. This includes integrated data and energy management solutions that enable you to achieve your low-carbon goals.

What is a MOP DCDA?

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 with DCDA solutions.

That means we manage the complete metering, collection and aggregation process in-house. This allows us to maximise the efficiency and accuracy of the data we provide you. Having a consolidated data partner also minimises the billing risks which can arise in the data supply chain.

FAQs about Meter Operator contracts

What is a Meter Operator Agreement/Contract?

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

Can I choose my half-hourly meter operator?

Yes. A meter operator contract is no longer part of the standard supply agreement with your energy supplier. That means you are entitled to choose your own half-hourly MOP based on your specific requirements. There is comes with significant advantages. If you do not appoint a half-hourly meter operator independently, your energy supplier will likely appoint one on your behalf, usually their preferred half-hourly MOP.

How are customers charged for half-hourly MOP services?

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

How do I switch half-hourly Meter Operator Provider?

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

Does a MOP agreement include collection and aggregation of my consumption data?

You are free to choose different companies for half-hourly MOP and DCDA services. However, it is highly advisable to combine this solution in order to reduce issues in 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.
