Your responsibilities as a fluorinated gas (F gas) wholesaler or reseller.
You can only sell F gas to customers that:
- hold relevant certificates and qualifications
- employ people that hold the relevant certificates and qualifications
If you sell F gas to a customer who will install, service, maintain or repair equipment containing F gas (or uses F gas to function), you must check that the customer holds individual qualifications or employs people holding a qualification.
If they’re doing this work on behalf of someone else, you must check that the customer has relevant company certificates.
You must keep records of:
- the customer’s certificate number
- quantities of F gases they buy
You must keep these records for at least 5 years and show them to your regulator when asked.
A person without qualifications may collect, transport or deliver F gases.
Get a letter of assurance from F gas customers
You must get a letter of assurance from every customer you sell F gas to. You need this letter if you’re a:
- wholesaler selling to a reseller
- wholesaler or reseller selling to a certified or qualified engineer
- wholesaler or reseller giving gas to a customer for collection, transport or delivery, that has been bought by a certified or qualified engineer
You can download aand ask your customers to complete it.
In the letter, the customer must confirm that they are permitted to buy or collect F gas and that:
- they will not release F gas into the atmosphere intentionally, unless technically necessary for the use of the F gas
- they will take all steps to prevent F gas leaks
Get a letter from end users of F gas equipment
If you sell stationary refrigeration, air conditioning, heat pump and fire protection systems, you must get a letter from the end user to confirm the details of the qualified technicians they are using to:
See guidance on:
You don’t need this letter if the equipment is hermetically sealed - that is if:
- a part of the product containing F gas is permanently sealed, for example welded or brazed shut, even if it has capped valves or service ports
- the product has a tested leak rate of less than 3g per year
It is against the law to buy F gas or sell F gas to a person if the person buying does not have the correct qualifications or certificates. If you do, you could receive a civil penalty. See the Environment Agency enforcement sanctions policy.
If you see someone breaking the law on F gas, report it to email@example.com
