    Installed a hive, won’t bore you with the details but I need to bridge the old thermostat terminal in the junction box. Is it the blue and brown I need to bridge? As with other threads, boiler won’t fire. Gravity fed hot water system, boiler needs water on for heating...

    Looks like brown to green/yellow (number 3), looks like cpc (earth colours) has been used as switch live? Just check wiring

    It would seem from what is seen the damaged green/yellow is switched line, brown is permanent line and blue is neutral and in fact there is no earth.
