The church's oil-fired heating boiler, installed 35 years previously, had come to the end of its working life and spare parts were no longer available. The churchwardens sought permission to replace the boiler with a new gas boiler. The Diocesan Advisory Committee expressed its disappointment that the church had not opted for a more environmentally friendly heating system. The Chancellor granted a faculty, being satisfied that the petitioners had considered the Church of England's 'Net Zero Roadmap' and the Church Building Council's guidance, and that the petitioners had also considered several alternative options, which had been discounted for various reasons, including costs, aesthetic considerations, and the potential impact of the different proposed solutions on the fabric and special character of the Grade I listed building. The Chancellor made it a condition of the faculty (inter alia) that so far as was practicable, gas supplied under a green tariff was to be used for the new system.
