how easy is it fit anew presure clock on the front of myworcester boiler 35?

yes it should be staight forward. just turn the service valves for the heating pipes underneath the boiler of. drain the the heating boiler down to 0 pressure. remove the cover from and just follow the part your changing and replace it to a new one. download the installers manual from the worcester site. it will give u a good idea what ur up against.
