air-conditioning repair cost

How much does air-con repair or a regas cost?

Quick answer

£90£900

At a UK independent garage, including parts, labour and VAT. The price covers a regas and leak test at the low end, condenser or compressor replacement at the top. Franchise dealer pricing usually sits 40-80% higher, and prestige or electric models sit at the top of the band.

Symptoms that point at it

  • air only cool, never cold
  • cold for ten minutes then warm
  • rattle from the front when the air-con engages

Run it on max for five minutes on the test drive. Air that never gets properly cold is a leak, and a leak is a part, not a regas.
