My boiler is inside a cupboard in the kitchen. It is a new Worcester Greenstar Ri. There is space in front and at one side where I would like to put a few seed trays for my tomato/cucumber seeds but I seem to recall reading somewhere that the cupboard must be completely empty. Is that correct? When my neighbours were away on holiday when the Beast from the East first struck (2018?) they rang to ask me to switch on their boiler as it was March and they'd not bothered to leave the heating on. Their boiler cupboard was full of stuff, mainly paperwork including the instructions for the boiler. Everything seems fine next door so am I worrying too much about a bit of plastic and some compost?
