We have added a £1 Central London fee to every Standard Class trip that starts or ends in London’s Ultra Low Emission Zone, to reduce congestion and pollution in Central London. The Central London Fee operates 24/7, and the fee is a part of the fixed fare shown when you book a ride. The fee is applicable only on trips that start or finish within the Ultra Low Emission Zone, meaning it will not be included on rides that only pass through such zones. Any credits or promo codes applied to your account, will be used against the Central London Fee. The Central London Fee is also subject to surge, meaning that the cost may increase during busy periods when demand for rides is high.
