Frequently Asked Questions
Who services the gas boiler in an Islington Council home?
The council arranges servicing through its appointed teams and contractors. Contact its repairs service to report a breakdown or confirm your appointment, rather than arranging private work yourself. Explain whether heating, hot water or both have stopped, and provide any displayed fault code.
My Barnsbury or Canonbury Victorian conversion is rented: what gas paperwork does the new licensing scheme require?
For rented homes with gas appliances, landlords need an annual landlord gas safety record and must give tenants a copy. The additional licensing scheme operating from February 2026 includes qualifying section 257 converted flats; classification matters. A boiler service does not replace the required gas safety check.
Do you cover Angel as well as Islington?
Yes, we cover Angel as well as Islington, including N1 addresses. Call with your full address, boiler make and symptoms so we can discuss the job. Our phone line is answered 24 hours a day, seven days a week, including weekends.
Can you repair my boiler the same day in Islington?
Same-day appointments are available in Islington, but completing a repair depends on the fault and any parts needed. Call with the model, display code and pressure reading to discuss availability. Tell us whether you have lost heating, hot water or both.
How often should a boiler in an Islington flat be serviced?
Arrange servicing annually, following the boiler manufacturer's instructions and warranty terms. This applies to an individual gas boiler in a flat just as it does in a house. If your heating is communal, contact building management to find out who maintains the system.
