  • Call Corva for urgent attendance enquiries; availability must be confirmed.

Describe what has stopped working

Is the problem heating only, hot water only or both? Is it every tap or just one outlet? Has the boiler stopped completely, or does it try to start? These details help the office understand the job. Mention when it began and whether it follows a power interruption, cold weather or recent work.

If there is an immediate safety concern, use the emergency guidance above instead of investigating. Otherwise, look at the normal display and controls without opening covers. Do not touch wet electrical equipment, exposed wiring or hot components.

Use the manual for ordinary checks

Check the heating schedule and the settings you usually operate. Read any visible message exactly as shown, including letters and numbers. Some display symbols describe a normal operating mode rather than a fault; the meaning depends on the boiler model.

A reset is not a universal repair. Only use a reset procedure where your manufacturer’s user instructions say it is appropriate, and do not repeatedly reset a fault that returns. Avoid online instructions involving the casing, gas supply components, wiring or internal parts.

Arrange the right help

Call 01745 507102 with the property postcode, boiler details and symptoms. Tell the team if the home has no other source of heat or if the situation affects someone with additional needs. Emergency calls are answered 24/7; the team must confirm attendance, scope and charges.

If you rent, also follow your landlord or managing agent’s repair reporting arrangements so access and authorisation can be agreed. For a boiler under a manufacturer’s guarantee, have the paperwork ready and ask about the correct claim route before authorising a chargeable repair.
