    Hi,

    I have recently moved into a house and the new boiler system is quite confusing. I can't work out how to increase the pressure which is at zero (it doesn't seem to be a key / keyless system per the Worcester website assistance). Picture of the boiler set up below. A lot of the wall switches for the boiler are off - does anyone know what they do? I have a service coming up next week, but would like to re-pressurise asap to avoid any potential damage. Many thanks for any assistance.

    your boiler doesnt use the plastic key system that you refer to, you will have an external filling loop somewhere, usually a silver braided hose that joins two pipes but the hose might be disconnected, I cant see it in your pic but it should ideally be in there somewhere

    No that is the expansion vessel communication hose, the hose you are looking for is similar but usually shorter and must connect between the cold water mains and the CH return pipe, usually near the boiler so that you can see the gauge when filling but have seen them in some crazy places, but overall yours looks not too bad an installation.
