Depends on whether it's commercial or not.
I like to make early starts most days.
On site at 6.30-7.30 often during spring-early autumn, hit £100/£120 by noon and do another £70/80 domestic in the afternoon, twice a week ups my averages. (Generally start last house no later than 4pm, so finish between 4.20 and 4.30)
Winter - don't like it freezing - so about 8 am commercial, 9.30 domestic. Finish 3.30/4pm. I'm happy to get in £100 on domestic plus a bit say £10 for fuel etc.
Domestic, outside winter- generally 9 am, but often 8.30 starting on a house where I know the owner has left for work.
