Can anyone please recommend a plumber to look at a boiler asap? We think it just needs to be repressurised but it's more complicated than other boilers I've repressurised and can't figure it out. The people who service it don't have an appointment available for a week and we are very cold :( Advice may also be useful - it's a Worcester junior 24i and needs a small hose connected to two valves to increase the pressure but that's as much as I can figure out
