Aphids are around in Peterborough, but possibly not in the proportions of previous years. Perhaps they're missing the luscious shoots encouraged by summer rain, which we have NOT seen in any meaningful quantity for months.
Broad bean pods have a nice overcoat of blackfly, and 'soft' bedding like nicotiana has greenfly.
There are a few woolly aphid appearing on my apple trees, but I treat at first sight with the soapy spray SB Plant Invigorator. I'm also using this as a regular preventive spray on greenhouse cucumbers to avoid red spider mite and whitefly taking hold, and it appears to be working.
