The church is at the west end of the village, opposite Carshalton Ponds, on the south side of the A232 going from Croydon to Sutton, as shown on this map. There are two public Car Parks in Carshalton High Street. Parking at the west end of church is in 2 hour limited bays; these are watched by wardens! Better to park in 'The Square' or 'Brookside' off the High Street at the east end of the church.
To Carshalton station with a 7 minute walk, or Carshalton Beeches station with a 15 minute walk.
Here is a map with an arrow showing the location of the church. It has no letter-box, and hence no post-code; the nearest is SM5 3PD. You may find the Transport for London website helpful in planning your journey.
