Comparing central heating costs

For the vast majority of people, no matter what you use to heat your house you are exposed to a greater or lesser extent on world fuel prices. The fluctuations in these costs will determine whether you find yourself paying an increasing or decreasing amount to keep your home warm.

Earlier this year those households using home heating oil got a huge boost as the cost of crude dropped sharply. The oil price has recovered somewhat but has still not returned to where it was at the start of the ye...

Fall in demand limited size of Power NI price cut

The Electricity Regulator has welcomed the near 5% reduction in Power NI's tariff. The decrease which will come into effect at the start of July will reduce the average household domestic electricity bill by close to £30. However Jenny Pyper says the cut would have been much more significant had it not been for a fall in total electricity demand as a result of Covid-19 which left fixed costs being smeared over a smaller number of units.
