customers are provided with the correct equipment for their needs, that it is installed, commissioned
and serviced in accordance with the manufacturer’s instructions by competent persons and that it
meets the requirements of the appropriate Building Regulations. The Benchmark Checklist can be
used to demonstrate compliance with Building Regulations and should be provided to the customer
for future reference. Installers are required to carry out installation, commissioning and servicing work
in accordance with the Benchmark Code of Practice which is available from the Heating and Hotwater
Industry Council who manage and promote the Scheme.

Gas Safe registered engineer. If you would like heateam to carry this out please call
on 0844 879 7690 or visit www.heateam.co.uk
Our promise to you
If you experience a fault with your new boiler, we aim to provide a safe and high
quality repair service supported by our dedicated national network of highly skilled
engineers. If your installer can’t resolve the problem for you, we will do everything we
can to get an engineer out to you as quickly as possible. Nothing in this warranty will
affect your statutory consumer rights.
What you need to do if you experience a problem with your heating system or
the operation of the boiler.
You should always contact your installer first, because the cause of the fault may not
be related to the boiler. If your installer confirms that the fault is with the boiler and
he / she can’t repair it, our friendly customer service team is on hand to help. Simply
call our service division heateam on 0844 879 7690 to book an engineer visit or for
any general advise that you may need. Our contact centre is open Monday to Friday
8am - 6pm, weekends and bank Holidays 8:30am - 2pm, excluding Christmas Day
and New Years Day.

What the warranty covers
• Free of charge repair or replacement of components found to be of faulty manufac-
ture.

is related to a manufacturing fault that cannot be repaired or is uneconomic to
repair.

ting from corrosion.
• Any other defects or failures, either in the connected heating system or outside of
the boiler itself.
• Faults caused by inadequate supply of electricity, gas or water to the property.
• Installations within commercial settings for which this boiler was not designed.
