The rate is £18 per hour.
The hourly rate is inclusive of VAT, but exclusive of travel expenses. Travelling time will be charged if this exceeds half an hour one way.
Support can vary from a few hours up to a few days per week, to be stopped at any time, without any long-term obligations.
Regular support will be invoiced fortnightly.
I live in North-West London, but am happy to visit elderly Dutch citizens in Greater London or outside the capital, within a reasonable distance.
