In line with the UK goal to reach carbon neutrality by 2050, the combination of photovoltaic electricity and the electrification of heating systems is considered an effective way to reduce greenhouse gas emissions, while 88% of schools in the UK are gas-heated. This paper analyses the electricity consumption at a 15 and 30min resolution of different scenarios for the retrofitting of a primary school in London, UK, with an electrified heating system and the electricity production of different PV installations. Without a battery storage, thanks to high temporal resolution assessment, only 35 to 47% of the school energy consumption can be met. High temporal resolution allows consideration of to economic balances and the possibilities PV can have on decarbonizing heating systems in UK primary schools
