Recommendation for Aircon specialist, Surrey ?

[Cee Gee]

Can anyone recommend a specialist for Porsche A/C please?
My 993 was re-gassed when I purchased the car earlier this year, but is now not working.
It could do with a thorough inspection and overhaul.
It's an aftermarket installation, mainly Porsche bits, but a Sanden compressor.
Guildford area, but willing to travel an hour or so for a really good specialist.

Thanks in advance
