Heathrow & Gatwick: Parking / Theft problems?

Hi all,

I know there is bike parking at both Heathrow and Gatwick, but has anyone experience of what the facilities are like and whether or not there are any known probems with theft?

Many thanks.

parked loads of times with no problems… but Smiled did have his bike stollen from there…
as with any carpark it has its risks

use as many chains as you can if you are parking for more than a day

Tks for the info.

Parked dozens of times at both and never had a problem…even used to lock my lid to the frame.
