What is BSUoS?

Balancing System Use of System (BSUoS) is a charge included within your unit rate. This charge recovers the costs incurred by National Grid to balance the electricity system. Balancing effectively means ensuring that the total generation output exactly matches the electricity demand requirement, there being no surplus or deficit of generation at any time, to maintain the quality and security of supply.

What is TNUos and DUoS?

Transmission Network Use of System (TNUoS) and Distribution Use of System (DUoS). These charges cover the cost of transporting electricity across the transmission system and the distribution networks to industrial, commercial and domestic customers. Both of these costs are approved by Ofgem under price control frameworks. You can learn more about Non-Energy Costs here

What is VAT?

Value Added Tax (VAT) is a government-imposed tax on the sale of goods and services. There are currently two rates of VAT applicable to energy customers: where supplies are wholly or partly for domestic or charitable non-business use, that part of the supply qualifies for the reduced rate of VAT.

On supplies used solely for business purposes, VAT will usually be charged at the standard rate. Customers with qualifying use will need to submit a VAT Customer Declaration Certificate for each site to advise us what percentage of the supply meets the qualifying criteria set by HM Revenue and Customs (HMRC). Please note that VAT Declaration Certificates are not transferable between suppliers.

You can find more information about VAT here

What is Agreed Capacity?

What is Available Supply Capacity (ASC)?

Maximum Import Capacity (MIC) also known as Agreed Supply Capacity (ASC) refers to the limit of capacity for a site. It is set and charged by the local Distribution Network Operator (DNO), according to the kVA of a premises.

This fee covers investment and maintenance of the electricity network and can also be called the Agreed Service Capacity Charge. Customers pay a fee (per unit), through their suppliers' invoices and are according to the agreed capacity for the site. In theory, maximum demand should not exceed the agreed capacity at any time

What are LECs?

Organisations that pay the Climate Change Levy (CCL) can enter into agreements with suppliers to purchase renewable electricity. The Levy Exemption Certificates (LECs) are evidence of CCL exempt electricity supply generated from qualifying renewable sources. LECs will be redeemed by suppliers to HM Customs and Excise to demonstrate the amount of non-climate change electricity able to be levied that had been supplied to non-domestic customers in the given period.

What is an MPAN?

A MPAN (Meter Point Administration Number) is a 13 figure number provided by the local Distribution company at the time of a new service being installed. It is a unique reference number that provides the industry with the general location of the supply cable in question. It is vital information that should be taken to your supplier to enable the registration process to begin. Once registered to your supplier it will be used to arrange the install of your meter and to successfully update your electricity bill.

What is a Data Collector (DC)?

A Data Collector (DC) is an organisation accredited by the Pool Accreditation Body to carry out Data Collection for Half Hourly (HH) Metering Systems. The DC is appointed by the supplier to retrieve and validate metering data and forward it, by Metering System, to the Data Aggregator. The DC may, in some cases, be appointed by the customer but must always be accredited and contracted to the customer's supplier.

What is a Data Aggregator (DA)?

The agent appointed to aggregate the meter reading data which is received from the Data Collectors (DC) and subsequently forwarded to the Supplier.

You can learn more about DNOs, MOps and DA/DCs in our Metering & Data video.


What is Maximum Demand?

Maximum Demand is the highest peak of usage (kWh) in any Half Hour during a calendar month or between two meter readings measured in either kW or kVA. This value is multiplied by 2 to give the MD on an hourly basis.

I have been advised that my change of supplier transfer was objected to. Why?

Existing suppliers are able to object to a customer leaving for a number of reasons. The most common of these are outstanding debt on an account, or the customer still being under contract. 

Who is responsible for advising the supplier of a move of location?

It is the responsibility of both the outgoing and incoming parties to advise the existing electricity supplier a change has occurred. However, the outgoing party is responsible until a final reading has been obtained/supplied. Find out more.

I have an Agreed Capacity (kVA) for my premise. Why am I being charged for excess availability?

The Agreed Capacity is the limit of capacity which has been agreed with the DNO. However; it is possible to use more than the Agreed Capacity on your property. Should this happen, the excess kVA will be applied to the additional usage. Find out more.
