This is the unique identifying number for your meter. It should be printed on your gas bill – usually on the first page or the reverse of the first page. The gas MPRN will consist of six to ten numbers and no letters. It differs from the meter serial number printed on the meter itself. If you cannot find it, contact us and we will be able to source it on your behalf.

Gas suppliers are the public face of the gas industry. A major part of their role is to pull together the costs of other parties in the gas supply chain. These third parties play a crucial role in producing and delivering your gas and the majority of their charges are regulated by the energy regulatory body, Ofgem. Suppliers build these infrastructure costs into your prices depending on the type of meter you have, its location and the type of contract you have with them. So these costs can be included in the unit price of your gas, charged separately as a standing charge or being itemised individually. They comprise the following:
1. Energy cost
This is the cost of the gas purchased on the wholesale market to cover your predicted future usage. It is the single biggest component of the unit price and accounts for upwards of 80% of a business’ total bill.
2. Infrastructure costs
These charges are paid by your gas supplier to the various participants in the gas market involved in importing, storing and delivering gas to your premises. They include a capacity charge for reserving capacity in the pipeline, gas store or other piece of infrastructure; fixed charges paid to National Grid or your independent gas transporter (IGT) for use of the network and gas meter; asset charges paid for the upkeep of the gas meter and network; unidentified gas charges to cover costs gas ‘theft’ or leakages from the network; read charges to cover the cost of reading the meter or an AMR charge if a smart meter has been fitted; and finally gas transportation charges. Costs vary by region and meter size and consumption.
3. Cost to serve
Costs incurred by your supplier to service your account. These include the costs of maintaining IT systems; paying the staff that manage your energy accounts; and the risks involved with your predicted consumption versus your actual consumption known as imbalance risk. This typically accounts for only a small part of your total bill, usually around 2%.

TOP is a common provision in larger gas contracts (and some larger electricity contracts) under which, if the end user’s annual purchased volume is less than the annual quantity of usage range specified in the contract, the end user pays for such a shortfall as if the gas had been received.

This is commonly referred to as a shipperless meter and may be due to incorrect or no asset information being recorded with National Grid or your independent gas transporter. This will result in gas being supplied to the premises without the customer being billed for it. Although this may sound attractive, it causes problems because your gas meter will not be maintained and gas transporters view this as theft. Eneco can help in remedying this problem. Send us two photographs of the meter, dated a couple of weeks apart, clearly showing the meter serial number printed on the meter. If the meter reading has moved on it will help us to confirm approximately how much gas is being used on site. We will also need a photo of the yellow Meter Asset Manager (MAM) sticker on the meter.
Contact Eneco to discuss this further and we will arrange supply contracts for your business.
