In reply to Postmanpat:
After decades of trying to find a truly long lasting breathable "waterproof" I finally discovered Paramo Analogy a couple of years ago. In terms of performance and hard wearing it beats any previous waterproof I've owned including The North Face, Berghaus, Peter Storm and Regatta, all of which performed well for about a year before failing even with regular re-proofing treatment.
Paramo also requires regular washing and reproofing, but it works, and performs like new every time.
As has been said the jackets tend to be on the "heavier" side, and wear very warm, being better suited for winter use, but you don't need to wear much under. In summer all I wear is a base layer.
Price wise you are probably looking in the region of £300, but you should be able to get that reduced with your BMC discount.
