Buy R32 UK: Complete Guide for Heat Pump and AC Engineers

Buying R32 Refrigerant in the UK

R32 has become the most important refrigerant for UK HVAC engineers to source reliably. As the standard gas for new heat pumps, split AC and multi-split systems from all major manufacturers, demand for R32 continues to grow year on year.

Why R32 Supply Matters

Unlike high-GWP refrigerants facing F-Gas quota pressure, R32 (GWP 675) occupies a relatively favourable position in the phase-down trajectory. It uses quota at approximately one-third the rate of R410A per kilogram, meaning supply constraints are less severe. However, seasonal demand peaks still occur — sourcing from a reliable UK-stocked supplier is essential to keep installations on schedule.

Standard UK Cylinder Size

The trade standard for R32 in the UK is the 9 kg cylinder. This size covers:

• Domestic heat pump charges of 0.8–2.5 kg with gas to spare for multiple top-ups
• Light commercial split AC charges of 1.5–4 kg
• Pre-commissioning lineset extension calculations

For high-volume workshop use or multiple installations per week, consider ordering multiple cylinders to maintain a working stock and avoid waiting for deliveries mid-job.

F-Gas Certification Required

R32 is an HFC refrigerant regulated under UK F-Gas Regulations. Only F-Gas certified engineers can purchase and handle R32. When ordering, you will be asked to confirm your certification status.
