Heating and cooling

Northern Ireland might finally be getting the heat pump grant system it has long lacked – in stark contrast to every other part of the UK and Ireland, where heat pump grants have been available to homeowners for years. More than one third of homes in Northern Ireland are heated with a particularly dirty fuel, heating oil, so decarbonising those homes is a particular challenge. A grant system would require new legislation, however, meaning that it would not come into effect until 2027 at the earliest – and knowing the Northern Irish political system, there is always the chance that major disagreements could get in the way of such legislation. Definitely one to watch, though.
