(EDIT September 2016 – the codes in this article, except for Hailo, still work OK so feel free to use them)
If the tube strike is going to leave you stranded on Wednesday and Thursday, you may want to give one of the app based cab services a go.
Let’s be frank – your chance of getting a ride is not going to be huge! (EDIT: Untrue! Uber is not running any surge pricing and has plenty of cars here in West London. Business as usual.)
These codes are all HFP ‘refer a friend’ codes except for Hailo:
Uber – £15 off your first ride with code headforpoints – download here
Hailo – £10 off your first ride with code STANDARD10 (expired 31 Aug) – download here
Gett (ex GetTaxi) – £10 off your first ride with code GTVVSHR – download here
Kabbee (pre booked minicabs) – £5 off your first ride when spending £10.01 or more with code [deleted as now expired] – download here
Uber will presumably be running surge pricing for much of the day. This means that you will pay a multiple of the standard rate. The rate generally increases to match supply and demand which means, if you are prepared to pay the price, you have a fair chance of being able to find a car.
That said, Uber was strangely quiet during the last tube strike – I had no problems getting a car at the standard price in Chelsea and South Kensington on two occasions, albeit both outside rush hour.
