The automotive air conditioning landscape has shifted significantly over the last decade, and for workshops across the UK, keeping up is no longer optional.
For years, R-134a was the refrigerant of choice across the industry. It was familiar, widely available, and the equipment to handle it was well understood. But since 2017, new passenger vehicles have been required to use R-1234yf, a lower global warming potential refrigerant that meets current EU and UK regulations. The result is that most modern vehicles rolling into your workshop will be carrying R-1234yf, while older vehicles on your ramp will still be running R-134a. Your team needs to be comfortable with both.
This is not just a question of having the right refrigerant in stock. R-1234yf requires dedicated service equipment. Cross-contamination between refrigerant types is a serious problem that can damage a vehicle’s AC system and create a safety risk, so using a machine designed specifically for R-1234yf is essential. The handling characteristics of R-1234yf also differ from R-134a. It has a mild flammability rating (A2L), which means technicians need proper training to work with it safely and legally.
That is where F-gas certification becomes critical. Under UK law, any technician operating automotive air conditioning service equipment must hold a recognised qualification. City and Guilds 2079 is the industry standard, covering the regulations, system principles, refrigerant handling, leak detection, re-gassing procedures, and the practical skills needed to work competently on both refrigerant types.
At AP Auto, we supply dedicated R-134a and R-1234yf service machines, the consumables and tools your team needs, and City and Guilds certified F-gas training delivered at our Gloucestershire centre or on-site at your workshop. Whether you are equipping a new bay or upskilling your technicians, we can help you get the job done correctly and legally.
