We live in 'greater London' ie tube zone four. I am currently paying £7 per hour for one child, plus a cab fare home which usually runs to £12. The other night we shared with a friend who had one child and upped the rate to £8, plus cab. We offered her £60 for six hours, did not look best pleased, so increased it to £65. It felt pretty steep to me! Do you think we're getting taken for a ride by this woman? The cab fare really doesn't help, I guess.
