The primary ferry route for drivers is from Dublin Port to Holyhead, Wales, serviced by operators such as Irish Ferries and Stena Line. The driving distance from Holyhead to London is approximately 430-460 km (265-285 miles) and typically takes about 4h 50m to 5h 15m. Fuel cost estimates are highly variable. UK roads feature limited tolls, mainly on the M6 Toll motorway and some bridges/tunnels. Driving into central London on weekdays generally incurs a Congestion Charge (currently GBP 15), and older vehicles may be subject to the Ultra Low Emission Zone (ULEZ) charge.
