Compliance result
CO₂-equivalent
16.70 tonnes CO₂e
8 kg × GWP 2088 ÷ 1000
Compliance band: 5 to 50 t CO₂e
Statutory leak check frequency
Annual leak check by an F-Gas certified engineer.
R410A regulatory status
Restricted in new equipment from 2025/2027 under F-Gas phase-down. Service permitted from reclaimed stock.
HFC blend — common on commercial AC and small air-cooled chillers installed 2005–2024.
Recordkeeping requirements
Full F-Gas logbook required — refrigerant type and charge, leak checks, top-ups, certified engineer details.
All refrigerant handling must be carried out by an F-Gas certified engineer under the UK F-Gas Regulation (Fluorinated Greenhouse Gases Regulations 2015 as amended).
GWP values follow AR4 as used by the UK F-Gas Regulation. Always cross-reference the equipment data plate and a current F-Gas guidance source before relying on a compliance decision. This tool is general guidance only — not legal advice.
UK F-Gas Regulation context
All refrigerant handling in the UK and EU must be carried out by an F-Gas certified engineer under the Fluorinated Greenhouse Gases Regulations 2015 (as amended). This tool provides general compliance planning guidance — not legal advice. Always confirm the current statutory position before a compliance decision and refer to Defra and the Environment Agency for authoritative F-Gas guidance.
