Hi there This is what would be classed as either at risk or not to current standards, to over come in the short term the window could have been screwed so it could not be opened, you would have to be more specific with the model of boiler, one thing to remember the manufactures instructions always override building regs. The only time it can be turned off and capped off is if it is classed as immediately dangerous which this is not, the Police have absolutely nothing to do with it what so ever ! Hope this helps Tim
