Half Hourly Metering

What is Half Hourly Metering?

Half hourly (or HH) metering is a kind of electricity meter. They calculate how much electricity is being used in every half an hour and automatically send a meter reading via a phone connection. They are a bit like a smart meter albeit using older technology. Because the meter is automatically understood, there is no need to take meter readings and will enable accurate energy bills to be delivered. Half hourly meters also help a business to check how much amount of energy they use at different times of the day, helping them become more energy-efficient and reducing expenditure. Half hourly meters also permit a supply to be specifically priced by the supplier who knows exactly how much is being used and when allowing them to create the perfect tariff for the business. This is in stark contrast to the situation with Non-Half Hourly meters which are subject to generic load profiles in order to estimate demand.

What kind of businesses has half-hourly meters?

There are approx 100,000 half-hourly meters in the UK and they are for businesses with high energy usage. They are compulsory for all business electricity customers with a maximum demand of 100 kW or more in any single half-hour period. This is known as a compulsory half hourly meter. Businesses with high demand of more than 70kW can opt to have a half-hourly meter.

How do you know if you have a half-hourly meter?

On your bill, The S number will help you identify if you have a half-hourly meter. If the S number has a ‘00’ in the upper left box, then you have a half-hourly meter

Is half-hourly meter pricing unlike standard pricing?

Yes, whilst the accuracy of your pricing against your actual consumption is increased by virtue of a half-hourly meter, the actual cost of the metering is significantly more expensive than with a ‘standard’ non-half hourly meter. This price differential is mostly insignificant for the heavy energy users that half-hourly meters are aimed at but the consequence is that they are unsuitable for low or medium users.

Can I switch half-hourly business energy tariffs?

Half hourly contract negotiation can be an implicated and complex process, due to constantly fluctuating wholesale market prices, variable supplier hedging strategies and the requirement for detailed demand data. But it is not impossible and throws up some fabulous purchasing opportunities, even more so than with a standard meter.
