Noval trailers used to be sold by B&Q. The UK importer dissolved a few years ago and with the high transportation cost and high Euro exchange rate, no-one is bringing in the trailers from France, this also includes spare parts. We are still able to get a few basic parts like wheels and spare light lenses as these tend to be fairly universal.
For anything a bit more specific, we would suggest a Franc dealer. Unfortunately, we are unable to recommend anyone.
We are trying to get a reliable supply all the time however this is proving difficult.
