I'm from the US, but have been very happy with etymotic brand earplugs. They have inexpensive ($15 USD) standard designs as well as custom-fit. Either sound much better than foam plugs.
I have the Interson Protac Pianissimo, with 25dB filters, I had them made at my local audiologist (Amplifon) a few years ago.
I am very satisfied, and I never suffered any kind of hearing loss or tinnitus after wearing these and while not perfectly linear, I could fully enjoy the music. If anything 25dB is a bit too much for "reasonably" loud events and I am tempted to buy extra filters with less attenuation for these events.
