^^ Rorain/nanoflex arm warmers are decent. Other arm warmers are also fine, but yeah... arm warmers.
Other good things? All the usual really. I ride with a cap and a buff pretty much throughout the winter.
Merino baselayers - boring and obvious answer, but I'd hate to be without those. Baselayers with windproof fronts are great too, they extend the use of summer jerseys through the UK winter.
