ENERGY MANAGEMENT > METER OPERATOR CONTRACTS

Meter Operator Agreements

MOP contracts are often overlooked, but that is starting to change. As the UK energy market moves towards Market Wide Half Hourly Settlement (MHHS), accurate metering and the contracts behind it are becoming far more important. What was once a background detail is now a key part of managing cost, data accuracy, and overall energy performance.

What Is a MOP Contract and Why Does It Matter More With MHHS?

For many businesses, MOP contracts sit quietly in the background of an energy contract. They are often overlooked, rarely reviewed, and sometimes arranged by the supplier without much visibility. But with Market Wide Half Hourly Settlement, also known as MHHS, metering is becoming much more important.

As the electricity market moves towards more accurate half hourly data, your meter performance, contract setup, and data reliability can have a direct impact on your energy costs.

What Is a MOP Contract?

A MOP contract, or Meter Operator contract, covers the installation, maintenance, and ongoing management of your electricity meter.

It is separate from your electricity supply contract and is usually required for sites with half hourly meters.

If you do not appoint your own MOP, your supplier may appoint one for you. This can often result in higher default charges and less control over your metering arrangements.

What Is MHHS?

Market Wide Half Hourly Settlement is a major reform of the UK electricity market.

In simple terms, MHHS means:

  • Electricity usage will be measured in half hourly intervals across more of the market
  • Billing will rely more heavily on actual consumption data
  • Accurate and reliable metering will become essential
  • Non half hourly sites will move closer to the half hourly model

This means metering can no longer be treated as a background detail. It will play a bigger role in cost control, billing accuracy, and energy management.

Why MOP Contracts Are Becoming More Important

As MHHS rolls out, the role of your meter operator becomes more critical.

Your MOP is responsible for keeping your meter operating correctly. If there are faults, delays, or issues with data quality, this can affect billing, reporting, and overall energy visibility.

MOP, DC and DA services may also become a more visible part of contract costs, rather than being hidden within wider supply rates.

That means businesses need to understand what they are paying for, who is managing their meter, and whether their current agreement is still competitive.

The Risk of Staying on a Default MOP Contract

Many businesses are still on supplier-appointed MOP contracts without realising it.

This can lead to:

  • Higher than necessary charges
  • Limited visibility over metering costs
  • Less control over supplier appointed arrangements
  • Poorer oversight of meter performance
  • Missed opportunities to optimise contract terms

With MHHS placing greater importance on accurate data, default arrangements are becoming harder to ignore.

A Simple Opportunity to Reduce Costs

Reviewing your MOP contract is one of the simpler ways to improve your energy setup.

A MOP contract review can help you:

  • Reduce unnecessary charges
  • Improve meter reliability
  • Gain clearer visibility over metering costs
  • Check whether you are on a default agreement
  • Prepare your site for MHHS
  • Strengthen control over your energy data

For businesses with multiple sites or half hourly meters, the savings and operational benefits can be even greater.
