Having a spare charged battery in your pocket is always a good idea (I've been doing it for years), so I'd go with that solution. According to the recommendations I've seen here, Anker (fulfilled by Amazon) seems to be about the best. USD22 on th US site, I have no idea what that would be shipped from the UK, but it's about 13GBP as far as exchange rate goes.
