What are MOA, SDS and ADS? New business energy data roles explained

The UK energy market is changing - again.

For years, businesses with half-hourly meters have had to deal with MOPs, DCs and DAs, all technical terms for people managing your meters and data behind the scenes.

But new rules are coming in that change this setup.

These new roles: MOA, SDS and ADS, will soon be part of every business’s energy landscape, whether you have a single smart meter or multiple sites with complex needs.

Don't know what these terms mean or why they matter? You’re not the only one.

We are here to explain what is changing, why it is happening, and how it affects your business in practical terms.

In this article:

• Learn what MOA, SDS and ADS are.

• Understand the new roles and how they affect your business.

• Discover what your business needs to do to stay on top of the changes.

What is changing?

If you’ve been responsible for energy contracts in the past, you may have come across MOP, DC and DA.

These roles are responsible for installing and maintaining your energy meter as well as collecting and processing the data to make it ready for billing.

If your business has a half-hourly supply, you’re legally required to appoint these roles. Many suppliers offer a default service, but choosing your own can save money and give you more control. These roles have formed the backbone of commercial energy data for years.

So, what's changing? Well, pretty much everything.

The UK is moving to a new process called Market-wide Half-Hourly Settlement (MHHS). This aims to ensure all electricity usage, whether from a smart meter or not, is settled every half hour. It’s part of a wider push to create a more flexible, responsive energy system that better reflects real-time demand.

To make this work, the industry is introducing new roles that replace or combine the old ones.

What is a MOA?

MOA stands for Metering Operations Agent.

This role is similar to the old Meter Operator, but broader. The MOA handles the technical side of your meter setup and makes sure it’s configured correctly to communicate with the data systems. They’re the link between your physical meter and the digital data world it needs to talk to.

What is a SDS?

SDS stands for Smart Data Service.

SDS is a new name for a new kind of data handler. It applies mostly to non-half-hourly meters (for example, smart meters on smaller sites). The SDS takes daily readings and turns them into half-hourly data so they can be used for settlement. In short, they make your smart meter smart enough for the new system.

What is a ADS?

ADS stands for Advanced Data Service.

This is the new role for half-hourly data. It replaces the old DC role for HH meters and includes some of the DA responsibilities. The ADS takes in the half-hourly reads from your meter, validates them, and sends them into the central settlement systems.

In many cases, these roles will be handled by the same type of companies that already act as DCs or DAs today but with updated systems and new responsibilities.

What does it all mean for your business?

If you’re not in the weeds of energy data every day, this might all sound technical. But there are three big reasons to pay attention.

1. You’re going to be affected: The new rules will apply to every business, not just those with traditional half-hourly meters. That includes smart meters, which will need to produce half-hourly data too. Whether you’re a single site or have a national portfolio, your data setup will need to evolve.
2. The supplier’s default might not be best: When these new roles come into force, your supplier will likely appoint someone for you, unless you take control yourself. That might mean paying more than you need to or missing out on better service and visibility.
3. Better data means better decisions: When your usage data is collected and processed accurately, you get clearer insights into how and when you use energy. That can help with everything from budgeting to sustainability reporting. And with the right provider, you can access this data easily, in formats that make sense.

How to prepare

The rollout of MHHS will run until 2027, but businesses are already making moves to get ahead. Here’s what you can do now:

• Check what kind of meter(s) you have and whether they’re currently settled half-hourly.
• Talk to your energy partner or broker about your current DC and DA setup.
• Consider consolidating your data and metering roles under one provider to reduce complexity.
• Ask what’s involved in switching to MOA, SDS or ADS support early, it could make your transition smoother.
• Make sure you have access to your energy data. If you don’t, it’s time to ask why.
