Half Hourly and Multi-Site Procurement

Obtaining prices for commercial half hourly (HH) electricity requires specialist knowledge of the energy market to manage the supplier procurement process. The procedure is different from smaller businesses maximum demand meters because the data used is accurate rather than estimated.

Half Hourly Meters

Half hourly metering is mandatory for businesses with peak loads of electricity in excess of 100kW. These types of meters provide accurate consumption data for billing purposes by automatically reading the device every 30 minutes.

Non Daily Metered (NDM) gas users can also have an Automated Meter Reading device (AMR) fitted to transmit usage data automatically. Some gas and electricity suppliers, such as CNG and Gazprom, insist that your meter has an AMR installed.

How Do I Obtain Competitive Prices?

Using our efficient and unique methodology ensures you receive the lowest possible electricity tariff for your properties. Multiple sites under one agreement together with half hourly electricity meters can't obtain automatic quotes.

The Half Hourly Procurement Process

These types of meters consequently require traditional negotiation methods. The tendering process works as follows:

  1. Call our dedicated team on 0800 002 9822 or enter your details on our pricing page.
  2. We'll ask you to complete a Data Release Letter that enables us to obtain your current consumption data for the past year.
  3. Using this information, we ask each energy company to bid for your contract.
  4. Our relationships, together with specialist "group buy" or "basket" pricing, enables us to beat other brokers by up to 10%.
  5. Select your preferred option to conclude the process. We'll process the necessary paperwork to update your contracts.

Tender pricing is usually only valid for 24 hours, so the process is fluid but time critical.

Multi-Site Tendering

If you own more than one building, we bundle these together during the procurement to leverage your buying power and maximise discounts.

Total consumption and efficiency audits can also be arranged to ensure you have the right class of meter installed. Changing meters takes advantage of differences in day, night and weekend tariffs.

What Data do I Need for Renewal Quotes?

Your consumption data is collected and stored by your current provider. You can usually only access the information once you've provided a letter of authority by yourselves on company headed paper.

This data, together with your building address with postal code, is sufficient to obtain the latest electricity prices. Not all power companies will bid on your contract, but the majority will offer competitive quotes.

Accurate Consumption and Energy Management Software

There are two main features and benefits of these meters.

Automated Meter Readings

Firstly, your consumption data used to calculate your bill is always 100% accurate because of the automated readings collected.

Energy Management

The second more important advantage concerns management information and analysis. Software programs allow you to import the raw data collected to analyse trends and produce energy management reports. You'll be able to check and monitor consumption for any cost centre or premises you manage.

Today's advanced software packages can create alarms if usage is over a certain threshold. You can highlight variances against historical trends from the information produced. Most companies save an additional 10% on an annual basis by using these advanced analytical tools.

New P272 Legislation


A change to the entire business energy market is underway to move all users to HH meters over the coming years. The migration starts with those businesses using 05, 06, 07, and 08 meter numbers. Smaller businesses with 03 and 04 profile classes are set to migrate at a later date.

The regulator Ofgem initiated the P272 legislation change to manage the Balancing and Settlement Code of the electricity used. Currently, prices are based upon the yearly usage rather than the time of the demand placed.

Current P272 Timetable

The migration timetable is as follows:

  • Project start date 5th November 2015.
  • Any meter with a profile class of 05, 06, 07, or 08 is migrated with a Change of Measurement Class (CoMC) to a HH settlement when their contract renews.
  • All companies using this class of meter must be changed by 1st April 2017.

What are the Benefits of Changing?

Once moved to HH settlement, your consumption data is transmitted to your provider every 30 minutes. Like all current HH electricity meters, you'll also get access to the data yourself to perform trend and analytical research. The data can help manage the consumption of your business over time.

Are there any Drawbacks or Risks?

Much like contract renewal, the risks of doing nothing have the greatest consequences. You should compare prices from different providers while proactively managing the change of HH settlement.

Taking Control of the Migration

Although all companies with a profile class (PC) between 05 to 08 are using Automated Meter Reading (AMR) type meters since April 2014, the settlement is not on a HH basis. The meter is unlikely to change physically with all HH settlement changes configured remotely.

You may want to appoint a Meter Operator (MOP), Data Aggregator (DA), or a Data Collector (DC) to manage the process. If you don't, your electricity provider appoints one on your behalf. All these agent services must have regulatory approval. You should notify your electricity supplier of any contracts you have in place.

Assigning a Meter Operator Contract

Half hourly electricity meterAll HH meters require a Meter Operator agreement to install and maintain the service.

These organisations can also provide management software to collect and analyse your usage data. You can use the default services from your supplier or appoint one yourself.
