Apologies if this has been covered - a quick search suggested not.

Is anyone else annoyed at the charges that Heathrow are currently imposing for parking at T5? I understand that only the short-stay is open at present, but quoting almost £150 for three-and-a-bit days (OK, four days) is, to me, outrageous. BA have switched my flight (at the end of July) from LGW to LHR; the parking cost is enough for me to consider cancelling my trip!

I am looking at alternative parking providers, but it's all a bit of a muddle (understandably); I have always used the official Heathrow car-parks until now.

Public transport is not an option in this case.
