Code Of Practice

For the installation, commissioning and servicing  
of domestic heating and hot water products

Benchmark places responsibilities on 
both manufacturers and installers.*   
The purpose is to ensure that 
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. 
Installers are required to carry out work  
in accordance with the following:

Standards of Work

•  

Be competent and qualified to undertake the work 

required.

•  

Install, commission, service and use products in 

accordance with the manufacturer’s instructions provided.

•  

Ensure that where there is responsibility for design work, 

the installation is correctly sized and fit for purpose.

•  

Meet the requirements of the appropriate Building 

Regulations. Where this involves notifiable work be a 

member of a Competent Persons Scheme or confirm that 

the customer has notified Local Authority Building Control 

(LABC), prior to work commencing.

•  

Complete all relevant sections of the Benchmark 

Checklist/Service Record when carrying out 

commissioning or servicing of a product or system.

•  

Ensure that the product or system is left in a safe 

condition and, whenever possible, in good working order.

•  

Highlight to the customer any remedial or improvement 

work identified during the course of commissioning or 

servicing work.

•  

Refer to the manufacturer’s helpline where assistance is 

needed.

•  

Report product faults and concerns to the manufacturer  

in a timely manner.

Customer Service

•  

Show the customer any identity card that is relevant to 

the work being carried out prior to commencement or on 

request.

•  

Give a full and clear explanation/demonstration of the 

product or system and its operation to the customer.

•  

Hand over the manufacturer’s instructions, including the 

Benchmark Checklist, to the customer on completion of 

an installation.

•  

Obtain the customer’s signature, on the Benchmark 

Checklist, to confirm satisfactory demonstration and 

receipt of manufacturer’s instructions.

•  

Advise the customer that regular product servicing is 

needed, in line with manufacturers’ recommendations,  

to ensure that safety and efficiency is maintained.

•  

Respond promptly to calls from a customer following 

completion of work, providing advice and assistance by 

phone and, if necessary, visiting the customer.

•  

Rectify any installation problems at no cost to the 

customer during the installer’s guarantee period.

* The use of the word “installer” is not limited to installation itself and covers 

those carrying out installation, commissioning and/or servicing of heating  

and hot water products, or the use of supporting products (such as water 

treatment or test equipment). 

**Customer includes householders, landlords and tenants.
