Hi Mike:
Ok, I live in Quebec, Canada. Here, we have a different culture, different language, different laws and different terms for just about everything. I can get most of what others' can in English Canada/US. I have stuff available here that most of North America can't get, especially plumbing fixtures.
My last visit to England astounded me with the selection of goods available. I visited Selfridges in London and that was a real eye-opener. UK/Europe is no backwater. Your problem is you've got to find who has what. I daresay everything is available to you, you just have to find it. Somehow I can't believe that you don't have access to plastics. Brits have too long a history of tinkering to put up with such a void.
