Area of Operation As you can see, we operate throughout the whole western side of London, from the city in the east, out past the M25 to Windsor, Woking and ? in the west. To minimise travelling time, we tend to work in different areas on different days of the week. In this way, by grouping jobs together it can be surprisingly economical for us to carry out even small jobs a long way away from our base in Hammersmith.
