F-Gas Regulation : Customer Screening

F-Gas Regulation : Customer Screening

EU F-Gas Regulation Guidance Information Sheet 19: Customer Screening

This information sheet is aimed at companies selling bulk supplies of F-Gases. It provides details of the new customer screening requirements.

1. Background

This guidance is for organisations affected by the 2014 EU F-Gas Regulation (517/2014). The F-Gas Regulation creates controls on the use and emissions of fluorinated greenhouse gases (F-Gases) including HFCs, PFCs and SF6The 2014 EU F-Gas Regulation replaces the 2006 Regulation, strengthening all of the 2006 requirements and introducing a number of important new measures.

An important new requirement of the 2014 F-Gas Regulation is that companies selling F-Gases in bulk (e.g. in cylinders or drums) need to check that their customers have suitable certification. These new rules apply to all companies that supply F-Gases to contractors or to end users.

This Information Sheet provides details of the customer screening requirements. A screening methodology based on a “Letter of Assurance” from the buyer to the seller is presented and has been approved by the European Commission. It is not mandatory to follow this methodology, but if you choose to follow a different one it must meet the requirements of the Regulation in Article 6.3 and Article 11.4.

Other Information Sheets that may be relevant include:

A wide range of further guidance is available for other aspects of the EU F-Gas Regulation – see Information Sheet 30 for a full list and a glossary of terms. 

2. Rules for the sales of bulk HFCs

NEW: Customer Screening

Companies selling bulk F-Gases to contractors and to end users need to set up systems to ensure that they comply with new rules about checking customer certification and record keeping. Article 11.4 of the 2014 F-Gas Regulation requires that:

For the purposes of carrying out the installation, servicing, maintenance or repair of equipment that contain F-Gases, bulk supplies of F-Gases shall only be sold to and purchased by undertakings that hold the relevant certificates or attestations.

It is important that F-Gas suppliers understand the implications of this requirement and put appropriate procedures in place to comply with them. Key points to note are:

  • a)  The phrase “sold to and purchased by” puts legal responsibility on both the buyer and the seller. In the 2006 Regulation the legal responsibility was only with the buyer, hence there were no previous customer screening requirements.
  • b)  The “relevant certificates or attestations” refers to both Company Certificates and personnel F-Gas handling certificates and attestations. The precise requirements depend on what the buyer is using the F-Gases for (e.g. there are different certification requirements for stationary refrigeration and for air-conditioning in cars). The reference to “attestations” means that purchasers for car air-conditioning (MACs) are included in the screening requirements (as attestations are only applicable to this sector).
  • c)  A Company Certificate must be held by all contractors working for 3rd parties to carry out installation and maintenance work on (i) stationary refrigeration, air-conditioning and heat pumps and (ii) stationary fire protection systems. This includes sole traders as well as limited companies.
  • d)  A Company Certificate is not required for other F-Gas handling activities e.g. for working on mobile refrigeration and air-conditioning systems or on high voltage switchgear. However, personnel certification is required for these activities.

To establish a customer screening compliance process, suppliers should consider the categories of customers to whom they sell bulk F-Gases. These fall into the groups shown in Table 1. As shown in the table, each category has different certification requirements.

An appropriate screening process should take these customer categories into account and should also accommodate the new record keeping requirements described in Section 3.

3. Record Keeping Requirements

NEW: Record Keeping

Linked to the responsibility to check that purchasers are properly certificated is a new requirement to keep records about F-Gas sales. Article 6.3 of the 2014 F-Gas Regulation specifies that a seller must establish records of:

  • a)  The numbers of certificates of the purchasers
  • b)  The respective quantities of F-Gases purchased

Suppliers need to make such records available, on request, to the competent authority of the Member State concerned or to the Commission. Suppliers shall maintain those records for at least five years.

It is important to note that the Regulation refers to “certificate numbers” in plural. For those companies that hold a Company Certificate, one certificate number satisfies this requirement. For those without a Company Certificate, that are required to provide details of personnel certification, this means that a certificate number for each employee carrying out relevant F-Gas handling activities must be provided. Whilst this sounds onerous, it should be stressed to customers that they cannot manage compliance with Article 10 of the Regulation (training and certification) unless they keep their own up-to-date records about their employees’ certification status.

Table 1: Bulk F-Gas Customer Characteristics

1 Contractors only working on refrigerated trucks and trailers do not need a Company Certificate. The training requirements for this sector have not been fully clarified in the new Regulation. In the interim, the personnel certificates for stationary RACHP, based on Commission Regulation 303/2008, are appropriate.

2 Vehicles affected by MAC Directive 2006/40/EC

3 Service companies in the MAC sector do not need a Company Certificate. The personnel attestations for MACs, based on Commission Regulation 307/2008, are appropriate.

4 Other transport refrigeration includes small vans, iso-containers, trains, ships. Other mobile air-conditioning includes buses, trains, ships.

5 Service companies in the HV switchgear sector do not need a Company Certificate. The personnel certificates for HV switchgear, based on Commission Regulation 305/2008, are appropriate.

6 Certification is required when purchasing F-Gases for installation and maintenance activities. Manufacture of equipment and specialist use falls outside this definition. 

4. Compliance with Screening and Record Keeping Rules

To comply with these requirements it will be necessary to have a customer database. For each customer this must include (a) appropriate certification details and (b) an on-going record of the quantities of F-Gas sold. In most cases such a database will be computerised, although that is not mandatory.

It is important to note that ad hoc cash sales to an unknown customer could not be considered as being compliant. If a customer is not in your customer database they should not be able to purchase F-Gases until you have proof of certification.

F-Gas suppliers will need to approach each customer and obtain appropriate information to keep in a customer database. The data required for a customer screening database is dependent on the customer categories described in Table 1. Six different screening processes may be required, as follows:

1) Contractors holding a Company Certificate for work on stationary refrigeration, air- conditioning and heat pumps (RACHP) and fire protection systems (FPS) should provide you with details of their Company Certification. This is the simplest way of screening a customer. For many wholesalers this category covers the majority of their customers.

You should record 3 pieces of information:

  • a)  the name of the body that issued the certificate
  • b)  the certificate number
  • c)  the expiry date (UK F-Gas Company Certificates need to be renewed every 3 years).

Your customer should provide a “Letter of Assurance” providing certificate details (Click here to view or download example Appendices to this Information Sheet). Certification must be checked when you enter a new customer into your database and when the Company Certificate expiry date is reached (to check that the customer has renewed their certificate). The Commission has confirmed that it is not necessary to see a copy of each certificate if an appropriate Letter of Assurance is used.

As discussed above, all contractors carrying out installation and servicing activities on stationary RACHP and FPS must hold a Company Certificate. If they cannot show they have a Company Certificate you should not be selling them F-Gases. You should alert the Environment Agency if you are concerned that a contractor is operating without a Company Certificate.

2) Contractors or service companies that only require personnel with a training certificate or training attestation. As shown in Table 1, contractors working on refrigerated trucks and trailers, MACs in cars / vans and HV switchgear do not require a Company Certificate but they must prove they have staff with relevant personnel certification. This makes the customer screening process more complicated.

You should create a customer database entry based on a “Letter of Assurance” from the customer that confirms that their operations only relate to work on refrigerated trucks and trailers or on MACs in cars / vans or HV switchgear. The confirmation should specify how many staff hold a relevant personnel certificate or attestation details. You should request the certificate number for each trained employee (e.g. if the company employ 50 staff, a list of 50 certificates should be provided). It is the view of the European Commission that any contractor or service company that is operating in compliance with the F-Gas Regulation should have such a list readily available – otherwise they cannot be certain that all their employees hold a suitable personnel certificate or attestation.

3) Contractors or service companies that do not require any form of certification. As shown in Table 1, companies working on “other transport refrigeration or other mobile air-conditioning” do not require proof of certification.

Note: Other mobile air-conditioning means mobile refrigeration outside of refrigerated trucks and trailers (e.g. containers, trains, ships) and mobile air-conditioning outside the scope of the MAC Directive (e.g. air-conditioning for buses, trains, ships). 

You should create a database entry based on a “Letter of Assurance” from the customer that confirms that their operations only relate to work “on other transport refrigeration or other mobile air-conditioning”. You can then sell them F-Gases and it is not mandatory to keep records of the volumes sold. Note, if a company does some work in this category, but also does work on stationary RACHP, then proof of Company Certification is required and records of quantities sold should be kept.

4) End users buying F-Gases for use in equipment such as refrigeration and air-conditioning are complex from a screening perspective. End users may be purchasing F-Gases for:

  • Use by their own staff that hold an F-Gas handling certificate (it should be noted that end users that employ certificated staff do not need to hold an F-Gas Company Certificate).
  • To issue the F-Gas to 3rd party contractors that hold appropriate F-Gas certification.
  • For use on “other transport refrigeration and air-conditioning” which does not require certification.

You should create a database entry based on a “Letter of Assurance” from the customer that confirms how they intend to use the gas purchased. If they are using the F-Gases with in-house staff the buyer will need to provide a list of certificate numbers for their staff. If they are issuing the F-Gases to contractors they should provide Company Certificate details for their contractors, to prove that the end user is checking the certification details of their contractors. You need to keep records of quantities sold to end users for use in installation or servicing activities.

5) Equipment manufacturers and specialist users that require F-Gases to fill new equipment in their factory do not need certification to be able to purchase bulk F-Gases.

  • Examples of equipment manufacturers are OEMs producing aerosols, RAC equipment, insulating foam etc.
  • Examples of specialist uses are SF6 and HFCs in magnesium smelting and use of various F- Gases in semi-conductor manufacturing, solvent applications and laboratory applications.

You should create a database entry based on a “Letter of Assurance” from the customer that confirms that they are either:

  • a)  an equipment manufacturer using the F-Gas to fill pre-charged equipment and products
  • b)  a specialist end user.

You can then sell them F-Gases and it is not mandatory to keep records of the volumes sold.

6) F-Gas Reseller that purchase F-Gases to sell to other customers in bulk. You should create a database entry based on a “Letter of Assurance” from the customer that confirms that they are an F-Gas reseller and that they will ensure that their customers are screened in accordance with the customer categories and certification requirements described in Table 1.

The customer database needs to be accessible by all staff selling F-Gas products. When someone from a particular customer collects some F-Gas, either in a cash sale or on account, your sales staff should check that they are authorised to collect gas on behalf of that company and that they have a suitable certification status in the customer database. The type and amount of F-Gas sold should be recorded in the database.

For customers that provided a Letter of Assurance based on personnel certification it is good practice to ask the company to renew their Letter of Assurance on a periodic basis, and so ensure that their operations have not changed in nature. Letters should be renewed every 1 to 3 years (the renewal period for UK Company Certificates is every 3 years).

5. Letters of Assurance

The Letters of Assurance referred to above should be standardised. The Commission has approved the approach described in this document, based on the example Letter of Assurance in the Appendix to this Information Sheet.

Each letter should:

  • a)  Identify the customer
  • b)  Give a general assurance that the customer is aware of the relevant rules in the F-Gas Regulation
  • c)  Give an assurance that the certification details provided are accurate
  • d)  Provide specific details about which customer category (or categories) is relevant.
  • e)  Provide related certification details if required
  • f)  Be signed by an authorised signatory.

An example Letter of Assurance is attached (Click here to view or download an example Letter of Assurance). This has been designed to cater for all types of customer.

The example Letter of Assurance can be used in the attached format, or modified to suit specific circumstances providing the key content is not altered. The most likely modification will be to create several letters that each address just one market category.

A copy of the Letter of Assurance from a customer should be kept for at least 5 years, as it forms part of the record keeping requirement specified in Article 6.3.
