Why refrigerant disposal matters for UK heat pump owners
Refrigerants used in heat pumps are classified as fluorinated greenhouse gases (F-gases) under UK law. Releasing them into the atmosphere is illegal and carries fines of up to £5,000 per offence in a magistrates’ court, with unlimited fines in a Crown Court (GOV.UK, 2026). The F-gas regulations require anyone handling or disposing of refrigerant to hold a valid F-gas handling certificate.
Refrigerant disposal for a UK heat pump costs £150-300 per system. This covers recovery by an F-gas certified technician, transport, and paperwork. Releasing refrigerant illegally carries fines up to £5,000 per offence.
- Refrigerant disposal costs £150-300 for an 8-12 kW heat pump.

Disposal is not optional at end-of-life or during a system replacement. The refrigerant must be recovered by a certified technician before the unit is scrapped. Improper disposal can lead to environmental harm and legal liability for the homeowner if traced back. The Environment Agency can issue enforcement notices and penalties for non-compliance (GOV.UK, 2026).
How refrigerant disposal costs are calculated
Costs depend on the refrigerant type and the charge weight in kilograms. Larger systems with higher global warming potential (GWP) refrigerants cost more to dispose of. GWP is a measure of how much heat a greenhouse gas traps in the atmosphere relative to carbon dioxide over 100 years.
Typical disposal fees range from £50 to £100 per kilogram of refrigerant, according to industry pricing data from the Heat Pump Association (HPA, 2026). Additional charges may apply for collection, transport, and paperwork such as waste transfer notes. The Department for Energy Security and Net Zero (DESNZ) guidance on F-gas disposal costs confirms that transport and administrative fees add £30–£60 to the total (DESNZ, 2026).
For a typical 8–12 kW air-source heat pump, the refrigerant charge is usually 1.5–3 kg. This gives a total disposal cost of £150–£300 per system.
The legal requirements for refrigerant disposal in 2026
Under the F-gas Regulations, only companies or individuals with an F-gas handling certificate (Category I or II) can recover refrigerant from a heat pump (GOV.UK, 2026). Category I covers full recovery and reclamation, while Category II covers recovery only. Both require an accredited training course and exam every five years.
The recovered refrigerant must be sent to an approved waste treatment facility for reclamation or destruction. Landfill disposal is banned under the Waste (England and Wales) Regulations 2011 (legislation.gov.uk, 2026). A waste transfer note (WTN) must be completed for each disposal, and the homeowner is entitled to a copy for their records. The Environment Agency recommends keeping this for at least three years (Environment Agency, 2026).
Quick numbers — refrigerant disposal at a glance
| Refrigerant type | Typical charge weight (kg) | Average disposal cost (£) | GWP value | Legal recovery required? |
|---|---|---|---|---|
| R410A | 2.5 | £125–£250 | 2,088 | Yes |
| R32 | 1.8 | £90–£180 | 675 | Yes |
| R290 (propane) | 0.5 | £25–£50 | 3 | Yes |
| R134a | 1.2 | £60–£120 | 1,430 | Yes |
| R407C | 2.0 | £100–£200 | 1,774 | Yes |
GWP values are from the DESNZ F-gas database 2026 and MCS refrigerant data sheets (DESNZ, 2026; MCS, 2026). R290 has the lowest GWP and is increasingly used in newer heat pumps, which reduces disposal costs.
Who is legally allowed to recover refrigerant from your heat pump
Only F-gas certified technicians (Category I or II) can legally recover refrigerant. This is a legal requirement, not a recommendation. Installers listed on the MCS register must hold F-gas certification to carry out decommissioning work (MCS, 2026).
For non-MCS work, check for F-gas certification via the REFCOM or F-Gas Register (GOV.UK, 2026). Homeowners cannot recover refrigerant themselves. Doing so is a criminal offence under the F-gas Regulations, with penalties including fines and potential imprisonment for repeat offences.
How to choose a certified heat pump installer
How to verify an installer for refrigerant disposal
Use the MCS installer search tool to find certified heat pump installers who can perform disposal as part of decommissioning (MCS, 2026). Verify F-gas handling certification via the REFCOM database or the Environment Agency’s F-gas register (GOV.UK, 2026).
TrustMark registration adds a layer of consumer protection for disposal work. TrustMark registered businesses are vetted for trading standards compliance and must hold relevant certifications (TrustMark, 2026). Always ask for the technician’s F-gas certificate number and verify it online before work begins.
What happens to the refrigerant after it is recovered
Recovered refrigerant is transported to an approved waste treatment facility where it is either reclaimed (cleaned and reused) or destroyed via high-temperature incineration. The disposal process is tracked via a waste transfer note and a certificate of destruction. Homeowners should request a copy for proof of compliance.
Reclamation rates for heat pump refrigerants in the UK are around 60–70%, according to the DESNZ F-gas progress report 2026 (DESNZ, 2026). The remainder is destroyed. The Environment Agency guidance on F-gas disposal and reclamation states that reclaimed refrigerant must meet purity standards before it can be reused in new equipment (Environment Agency, 2026).
The direct answer to “refrigerant disposal” for UK homeowners
Refrigerant disposal is the legal, certified recovery and treatment of the F-gas inside your heat pump, required under UK law at end-of-life or system replacement. You must hire an F-gas certified technician, pay £150–£300 on average, and keep the waste transfer note as proof. The cost varies by refrigerant type and charge weight, with R32 systems typically costing less than older R410A units. Always verify the technician’s certification via the GOV.UK F-gas register before work begins.
