Why has my NIROC and CCL charge changed on my bill?

Please note that with the beginning of a new obligation period, a new level of NIROC (Northern Ireland Renewable Obligation Commitment) will apply to electricity consumption in Northern Ireland from 1st April 2019.

Renewable Obligation

This charge is itemised as “Renewable Obligation” on your unbundled bill and will increase from 0.874 to 0.927 pence per unit from this date. OFGEM (Office of Gas and Electricity Markets) decides the level of this charge on an annual basis and publishes it on the OFGEM website.

Obligation period
(1st April-31st March)

Buy-out price
(per ROC)

Obligation level for
Northern Ireland (ROCs/MWh)

2018-2019 £47.22 0.185
2019-2020 £48.78 0.190


The price that is charged on your electricity bill is calculated using the following methodology:

The Buy Out Price of £48.78 is multiplied by the obligation level applicable to Northern Ireland: i.e £9.2682 per MW: which in turn equates to 0.927 pence per unit : (divide by a thousand to convert the units to a kilowatt base and multiply by a 100 to convert from pounds to pence)

Taxable Commodity

CCL (Climate Change Levy) is also increasing with the new rates for the various taxable commodities published on the Gov.UK website.

Taxable Commodity

Rate from 1st April 2018

Rate from 1st April 2019

Electricity (pence per kilowatt hour (KWh)) 0.00583 0.00847
Natural Gas (£ per KWh) 0.00203 0.00339

Also note that the percentage discount for holders of a CCA (Climate Change Agreement) will increase from 90% to 93% for Electricity consumption and from 65% to 78% for Natural Gas consumption.
