Record the boiler details
Send the make, model and any error code shown on the display. Explain what happens when heating or hot water is requested, when the problem began and whether pressure has changed.
Do not dismantle the appliance
Photographs of the front display and surrounding installation can be useful, but gas appliances should not be opened or repaired by an unqualified person. If you smell gas or suspect carbon monoxide, leave the area and follow official emergency guidance immediately rather than waiting for an online quote.
Add the property postcode
Include the postcode, best phone number, access times and whether the property is occupied by a tenant.
