The energy tax rates are set by law. For our purposes, the make-up of energy tax differs depending on the type of invoice.

Actual consumption
Energy tax falls into 4 zones. As of 1 January of each calendar year, you start off in the 1st zone, which has the highest energy tax rates. Thereafter, depending on your consumption, you progress through to the 2nd, 3rd and 4th zones, which have progressively lower tax rates. As a result, you pay more tax in January than in December.

Advance payment
Energy tax falls into 4 zones. We use your contracted annual consumption to determine in which tax zones your consumption falls. In your advance payment invoice, you will see 1/12th of your contracted annual consumption per zone. The total amount for the advance payment is based on 1/12th of your contracted annual consumption.

Under certain conditions you can claim a reduction in or exemption from energy tax. You’ll find the necessary declaration forms at the bottom of our homepage.

The advance is 1/12th of your contracted annual consumption.

Do you want to adjust the amount of your advance payment? If you have a valid reason, please mail to klantenservice@gulfgasandpower.nl. We'll check what we can do for you.

The grid operator is responsible for the transport of electricity and gas; maintenance of the pipelines, ducts and cables; and dealing with faults. As a client, you make a contribution to this in the form of transport costs: costs for the transport of energy from the power station to your business premises.

The method of redelivery varies between large and small consumption connections.

Large consumers
We calculate a redelivery rate. If you are going to install your own means of energy generation and not pass this on to us in advance, the redelivery fee is 75% of the delivery rates per kWh.

Small consumers
We apply the netting arrangements. The redelivery fee is equal to the contract price. If the energy you deliver exceeds your energy consumption, then the redelivery fee for this element is 75% of the contract price per kWh.

You may change your payment method. Simply mail: klantenservice@gulfgasandpower.nl.

Please note: if you have a small consumer connection, you pay €2.50 per month with your payment transfer. These charges are deducted from your annual bill in one go.

If your invoice is incorrect mail: klantenservice@gulfgasandpower.nl. We’ll be happy to review it with you.

If your final or annual statement is incorrect, mail: klantenservice@gulfgasandpower.nl. We’ll be happy to review it with you. 

It is unfortunately not possible to pay in installments. 

Electricity
A small consumer has a connection capacity of less than or equal to 3 x 80 amperes. A large consumer has a connection capacity of more than 3 x 80 amperes.

Gas
A small consumer has a maximum of one G25 gas meter that lets through a maximum of 40m3 gas per hour. A large consumer has a gas meter larger than G25 that lets through more than 40m3 gas per hour.

If you have an electricity meter with two counters you pay a lower rate during off-peak hours than during peak hours. Peak hours are 7am to 11pm and off-peak hours are 11pm to 7am. On Saturdays, Sundays and Public Holidays of-peak rate apply all day.

If you have two or more connections at one WOZ (Waardering Onroerende Zaken - Valuation of Property) address, then you only have to pay energy tax once for all connections. To arrange this, simply email your WOZ-verklaring to klantenservice@gulfgasandpower.nl.

Please note: if the energy is supplied by multiple suppliers, you should apply directly to the tax office (Belastingdienst) for a refund.

If you use natural gas as part of the process of growing horticultural products, then you pay the low VAT rate, as well as lower rates of energy tax and renewable energy storage. To arrange this, mail a completed Tuindersverklaring form to klantenservice@gulfgasandpower.nl.

A property with a ‘verblijfsfunctie’ (residential status) is a building that people can occupy and where electricity is consumed. For example, a domestic home or an office. If your property has such a residential staus, you pay less energy tax. This does not apply, for example, to garages, allotments or boat moorings.

Guarantees of Origin (GvOs) are green certificates. These are used as proof that the energy delivered has been generated sustainably.

The ‘Aansluit- en Transportovereenkomst’ (Connection & Transportation Agreement - ATO) is an agreement that the energy supplier, on behalf of the grid operator, makes with you at the moment you sign the supply agreement. The ATO describes your energy connection(s), which the grid operator maintains. For example, it states what your connection capacity is and who you can contact in the event of faults.

Please note: the above applies only to small consumer connections. If you have a large consumer connection, you sign an ATO with the grid operator yourself.
