Not a good idea if its established. If its newly planted you could risk it but even then in this weather it would need a lot of water regularly. Better wait until autumn.

You can move it, but its a risk. You need to dig it up so it doesn't notice, by taking enough soil round the rootball that you can't even see the roots, never mind break any, then replant immediately and keep well watered right up unti end of October. Otherwise wait till late autumn.

Personally I'd wait until late autumn this is just about the worst time of year to move any shrub.

Thanks everyone
