I work London. Just not Zone 1, dont know how anyone does it. Ball ache deluxe
It depends on which jobs in Central London you do and how you organise yourself.
Believe it or not there are plenty of properties in Zone 1 with parking. Alternatively clients are used to suspending parking bays to have services in their homes. Failing that you can order a resident bay permit online. Failing that I park illegally with emergency signs on and so far this year I have had one ticket. I make it quite clear to my clients that if I can't park the job won't be done and this seems to make spaces appear. Rather than it being ball ache I feel like I lead a charmed life swanning in to my reserved parking space.
In the past year I have used my Airflex Turbo twice and one of those was a commercial in Woking.
Any properties that can't be truck mounted I turn away or pass on to a fellow carpet cleaner. Thing is being a truck mounted operator in London is quite rare and it seems you can be a bit more picky about where you work and still have an overflowing diary.
Its all about knowing where and how you want to work and making it happen.
