A call came in from a property near Chancellors Court, just off Orde Hall Street in Holborn, WC1N β total heating failure, no hot water, and a household that had already been without heating overnight. Because this is our home postcode, Ralf was on site within the hour to carry out a full emergency boiler repair diagnostic.
When a boiler stops producing heat entirely β rather than just running inefficiently β the cause is nearly always one of a small number of faults: a failed ignition sequence, a tripped pressure switch, a faulty PCB, or a blocked condensate pipe causing the boiler to lock out as a safety measure. The property's boiler was displaying no error code at all, simply refusing to fire, which narrowed the diagnosis to an electrical or ignition-side fault rather than a mechanical blockage.
Ralf's approach on every emergency call is the same: isolate the system, check gas supply and pressure first, then work through the ignition sequence components in order rather than guessing. In WC1N's older converted buildings β common around Orde Hall Street and the wider Chancellors Court area β this matters more than in a newer build, because previous repairs or partial upgrades over the years can leave a system with non-original parts that behave slightly differently to the manufacturer's expected fault pattern.
The fault traced back to a failed ignition lead β a low-cost part, but one that stops the boiler firing completely when it fails. Ralf carried the correct replacement part on the van, fitted it, and confirmed ignition, flame sensing, and full heat output before leaving. Gas tightness was tested and the system was left running at normal operating pressure with hot water restored throughout the property.
For flats and converted properties in Holborn, a fast turnaround on emergency repairs is not a luxury β many properties in WC1N have limited alternative heating, and landlords managing tenanted properties near Chancellors Court need documented, same-day resolution rather than a multi-day wait for parts. Because Pristine Gas Ltd is based in WC1N itself, this kind of job is normally a same-morning fix rather than a scheduled callback.

A total heating failure with no error code is usually a failed ignition sequence, a tripped pressure switch, a faulty PCB, or a blocked condensate pipe causing a safety lockout. It rarely resolves on its own, so it is worth calling a Gas Safe engineer rather than waiting.
