The 1h07 estimate is a clear-roads baseline. In practice several sections each contribute their own variability.

Tooting Broadway and High Street Traffic
Tooting High Street and the Broadway area are among the busiest parts of SW17. Queuing during morning and evening peaks can slow departure significantly.

Garratt Lane / Mitcham Road Congestion
The roads south of Tooting town centre — Garratt Lane and Mitcham Road — are well-known local pinch points during peak periods. Your driver routes around these where possible, but the SW17 road network has limited alternatives.

Central London Road Conditions
This is the most unpredictable stretch of the journey. Events, road closures, and commuter volumes can compress what's normally a 15-minute section to well over an hour.

North-East London Traffic
Once clear of central London, the approach to the M25 and the M11 corridor carries its own congestion during weekday peaks.

M11 Conditions
North of the M25, the M11 is generally quicker — but roadworks near Harlow and the airport approach road add time during busy departures.

Stansted Airport Approach
Bank holidays and school-holiday peaks create notable approach-road queuing. Allow a small buffer on top of your drive estimate.
