Park homes in Greater London are scarce. A handful of residential parks sit on the edge of the city, and this page lists what is available.
Look at Enfield to the north, and Uxbridge and West Drayton to the west near the M4 and M25. Stock turns over slowly here, so it pays to check back or register for alerts.
If nothing on this page suits, the residential parks in Essex, Hertfordshire, Surrey and Kent sit within an hour of central London and carry far more choice.
