Frequently Asked Questions
How Do I Check Gas Safe Registration?
Inspect their current Gas Safe ID card and verify their licence through Gas Safe Register. Check the photograph, identity, expiry date and relevant work categories on the reverse. Business registration does not replace checking the individual engineer attending your property.
No Heating or Hot Water: What’s Wrong?
Several causes can stop both heating and hot water; assessment is needed. Describe symptoms and a safely visible code for boiler repair in London. Never open the boiler casing. Follow the emergency instructions above for suspected gas or carbon monoxide.
How Much Does a Boiler Service Cost?
Call with your boiler and property details for a price for your job. The appliance, access and service scope affect cost; remedial work needs separate assessment. Read about boiler servicing in London and discuss your visit’s scope before arranging attendance.
