No, you can't. Not bark thick enough to make anything from.
You can peel off thin, thin layers that flake on the surface of some varieties, but most of the birch trees in the UK grow thin barks. That's the bark that carries the water up the tree, that protects it from fungal attack, etc.,
Dead birches rot from the inside out, they leave the tube of bark behind. Try to find that instead if you want to use native bark.
Failing that buy Continental or N.American birch bark. It's much thicker, more flexible, less likely to split, it grows well in their cold climates.
Bambodoggy summed it up, "Trees don't heal, they seal"…unless you ring bark them or fungus get into them.
