Frequently asked questions
What should I do if I smell gas?
If you smell gas or suspect a gas escape, turn off the gas at the emergency control valve if safe to do so, ventilate the property, avoid using electrical switches or naked flames, leave the property if necessary and call the National Gas Emergency Service immediately on 0800 111 999.
Does diagnosis automatically mean the boiler will need parts?
No. The purpose is to identify the likely cause. Any repair or replacement work can then be discussed separately.
