Fully agree with the above, having used the drive-in chain type places for a few years, generally costing £35-75 even with their “offers” and finding that the system still needs topping up or work doing the following year, I switched to an independent specialist a few years ago. Guy really knew his stuff, came to me at work, spent a little longer with the car but did the job, found a couple of minor leaks at seals, regassed and didn’t need to call out again the following year. Cost £50.
Since changed car and moved house so used another similar company last summer, again, found some components to be replaced but the guy (seeing I already had the car in bits for other work) suggested I replace them myself to save on the labour cost and then get him back to test/refill the system - even showed me roughly how to do it.
