Visitors to Imperial College and those students wishing to move into or out of halls during the week must beware: with Imperial inside the western extension of the Congestion Charging zone it will cost £8 for the privilege. If you forget on the day, it will cost you £10, rising to a £50 fine the day after that. Failure to pay the fine within 14 days doubles it to £100.
College's limited space for parking means few people currently drive onto the campus on a regular basis, however the charge may free up some extra spaces for those already living nearby or for more portacabins.
Vehicles with 9 or more seats are exempt from the charge, so the Union's minibuses are unaffected. Boanerges, the CGCU motorised mascot is not so lucky - despite his exemption from road tax and vintage status, Bo' was refused exemption from the Congestion Charge when it was originally introduced. The charge was easily avoided by not straying into the zone, but now any journey out on weekdays (even just round the block) will require payment. The other motorised mascots are all exempt, by virtue of having 9 or more seats (Jez & Clem) or being a motorcycle (Derrick).
On the positive side, if you live in Kensington and Chelsea (which has 17 of the 20 most expensive streets in the UK) you now qualify for a 90% discount, letting you use your 4x4 for the purpose it was designed for at reduced cost. That purpose being driving into Central London to run over cyclists, of course.
TfL are expecting a 10-15% reduction in the number of vehicles entering the western extension.
