Baz dealt very professionally with a first fill-up of the aircon on my newly built kit-car. He gave me advice over the phone about putting oil in the compresso prior to coming to gas the system. He tested the system thoroughly for leaks before putting in the gas and checked for proper functioning of fans and over-pressure switch once the system was gassed. He took time to do a thorough job, his fees are reasonable and I can recommend him unreservedly.
