UK PASSPORT - URGENT!!!?

Mine was peeling a bit at the corner for about 8 years and I never got round to changing it. Only once was I questioned at Schipol Airport, and just asked if it had been like that for a while. I travelled to Singapore, South Africa, Russia, Ukraine, Turkey, the Baltics, Scandinavia, Malta, Cyprus, Israel, USA, Malaysia and pretty much most of Western Europe with the damaged passport.
