Lorna,,I would do 2 things. Firstly take cuttings...ideally look for strong non flowering side shoots low down. i see you have done that. 5 miles from the beach so similarly mild where you are.
if your plant isnt too huge.....cut it back and lightly trim the roots. Put into a pot big enough to fully accommodate the roots. Water to settle compost and roots and into gh. However, you should get a few more weeks yet with your flowers so give it say to mid October. Keep on dry side over winter. next spring, as with most plants in gh, lightly water when signs of growth and increase accordingly.
