To deal with more frequent calls asking how to start/restart wall-mounted boilers after a power/gas supply outage, we are publishing the following brief information:

  • The absence of natural gas in the residential installation is mainly due to power or gas disruption. In such situations, the system is automatically switched off as part of network safety.
  • To restart your boiler, turn off and on the appliance and if necessary, repeat the action several times. If the boiler is set in summer mode, open the hot water valve to make sure that the appliance is working normally.
  • If you need further information, you can always contact us on the National call centre - 0700 11 110, and in case of suspected technical fault – on our emergency telephone - 0800 11 211.
