The Parochial Church Council ("PCC") wished to replace the oil-fired boiler with a new oil-fired boiler. The Diocesan Advisory Committee considered that the PCC had not had "due regard" to net zero guidance, as required by the Faculty Jurisdiction Rules 2022. Before their petition had been considered by the court, the PCC arranged the installation of the replacement boiler. The PCC subsequently provided the Deputy Chancellor with information about alternative heating systems, which included a quotation for converting the oil-fired boiler to run on hydrotreated vegetable oil ("HVO") at some stage in the future. The Deputy Chancellor, in view of the PCC's declared aim to decarbonise its heating with the development of an eco-friendly heating system within the next 5 years, granted a faculty, subject to (a) the PCC undertaking accredited carbon offsetting, and (b) the faculty limiting the use of the oil-fired boiler until 2028, when any request for an extension would have to be supported by evidence as to whether there had been compliance with the offsetting condition and whether the boiler had by then been converted to HVO.
