What should a garage charge for an air conditioning regas in 2026?

Air conditioning is one of the few remaining jobs where an independent workshop can hold a proper margin, and it is also one of the few where getting the pricing wrong costs you real money per car rather than a few pounds. The reason is simple: the gas in a modern car costs many times what the gas in an older one costs, and a workshop running one price for both is losing money on half its customers.

Trade figures below are 2025 to 2026 ranges. Refrigerant pricing moves with supply, so treat the per kilogram numbers as indicative and check your own factor invoices before you set a price.

Two gases, and why the price doubles

R134a is what sits in most cars up to around 2017.

R1234yf replaced it as new type approvals moved across. Broadly, assume anything registered from 2017 is R1234yf, check anything from roughly 2014 to 2017, and read the label under the bonnet rather than guessing.

What that means to your costs, as indicative trade ranges:

	R134a	R1234yf
Trade gas cost per kg	£12 to £20	£90 to £140
Charge weight per car	450g to 750g	450g to 750g
Gas cost per job	£6 to £15	£45 to £100
Typical UK retail	£60 to £90	£150 to £250

That is the whole commercial story of this job. If you advertise one regas price, you are either overcharging every older car or subsidising every newer one, and in practice it is the second.

What the job costs you beyond the gas

• Time: 45 to 60 minutes including recovery, vacuum, leak hold and recharge, most of it machine time rather than technician time
• Consumables: oil and dye, £2 to £6 per job
• Bay: the machine is working, the technician is not, so the real question is whether that bay could be running a billable job alongside
• Filters and machine servicing: budget £150 to £350 a year, an estimate that varies by machine

The machine time point matters more than it looks. A regas that ties up a bay for an hour but only twelve minutes of technician time is good business if you can run something else in parallel and poor business if you cannot.

Machine cost and the payback formula

Indicative purchase prices:

• R134a only: £2,000 to £3,500
• R1234yf capable: £4,000 to £7,000
• Dual gas, both circuits: £5,000 to £8,000

The payback sum is straightforward:

machine cost / (retail price - gas cost - consumables) = jobs to break even

A £5,000 dual gas machine, an R1234yf job retailing at £180 with £70 of gas and £5 of consumables, gives £105 of gross profit per job and breaks even at about 48 jobs. On an R134a job at £75 retail with £12 of gas, gross profit is £58 and break even is 86 jobs. A typical independent doing air conditioning work through a season will land somewhere between the two.

If you are not going to reach those numbers, subcontracting to a mobile air conditioning specialist and taking a cut is the better commercial answer, and there is no shame in it.

The certification point

Handling refrigerant in vehicle air conditioning is regulated. You need the relevant F gas competence certificate, and deliberately venting refrigerant to atmosphere is an offence rather than a bad habit. The GOV.UK guidance on fluorinated gases is the reference, and the Institute of the Motor Industry lists the qualifications. Keep the certificates with your training records where an insurer or an inspector can find them.

The mistake that generates comebacks

A system that is low on gas is a system that is leaking. Refrigerant does not get used up.

So a regas sold on its own, with no leak test, is a job the customer will be back for. They will be back in six weeks, they will believe they have paid for nothing, and you will either do it again for free or have an argument. Either outcome costs more than the diagnosis would have.

Price it as two services and say so plainly:

1. Regas with pressure and leak hold test, at your standard price, on a system that holds
2. Leak diagnosis, charged at your diagnostic rate, when it does not

We have covered where diagnostic rates should sit in what to charge for diagnostics, and the same principle applies here: the skilled part of this job is finding the fault, not connecting the machine.

Put the outcome in writing either way. A line on the invoice reading "system held vacuum for 15 minutes, no leak detected at time of service" is worth a great deal three months later.

Seasonality, and how to use it

Demand for this work is concentrated between April and July, and most of it arrives as an afterthought when the first warm week hits. Two things make the season worth more:

Check it before the season. Every service and every MOT between January and March is an opportunity to note that the system is not blowing cold and book the work for April, instead of waiting for the phone to ring in a heatwave when you are already full.

Tell people you do it. Air conditioning is one of the jobs customers assume only a specialist does, so the workshop that mentions it, on the invoice footer, in the reminder text and on the website, gets the work from customers it already has. Our post on getting more work from your existing customers goes into the mechanics.

Where software helps

The commercial trap in air conditioning is that the price depends on the gas, and the gas depends on the car. Autera holds a separate priced job for each refrigerant type, so the right figure lands on the quote by vehicle instead of by memory, and the vehicle health check flags the systems you found not blowing cold in February so they can be booked for April rather than forgotten. Try it free for 14 days or look at the pricing.
