Current boiler is on its last legs! It is a two bedroom terrace, so I think a small boiler would be ok. Does anyone have any idea how much a new boiler would be? I know (think?) we would also need to get the pipes/rads flushed. Would we need a new digital control panel as well (currently a honeywell brand one)? Anything else we need to know/consider. Not in a British Gas area so no need to steer clear of them.
