The petitioners wished to replace the gas boilers at the Grade I listed church with new gas boilers. The existing gas boilers had been damaged by flooding. An initial request for like-for-like replacement was delayed because it failed to demonstrate “due regard” to the Church of England’s Net Zero Carbon guidance, which is mandatory under the Faculty Jurisdiction Rules. After criticism from the Diocesan Advisory Committee (DAC), the petitioners produced a detailed revised options appraisal assessing a wide range of low-carbon heating solutions. The appraisal concluded that a fully electric system was currently impractical due to inadequate electricity supply and cost, but proposed a phased approach: short-term replacement of gas boilers, followed by medium-term integration of air source heat pumps, and longer-term carbon offsetting. The Chancellor held that the petitioners had now properly engaged with the Net Zero guidance and that immediate heating was necessary for the church’s mission and community use. A faculty was therefore granted, but only on strict conditions: the new gas boilers must be hydrogen-ready, supplied on a green tariff, subject to carbon offsetting, and approved for a limited period of five years to 2030, during which progress towards low-carbon alternatives must be demonstrated.
