How much should I expect to pay for a taxi from LHR to LGW? The three of us are doing SFO-LHR transferring to LGW-VCE on a Saturday in April, I am considering the taxi option if the cost is not much more than £17 x 3.

Our last taxi trip from Portman square to LHR cost £115 on a Sunday morning. I was expecting to pay only around £60-70 and was glad that I had just enough extra cash.
