I believe you're SOL for complimentary access but no harm in asking. As an alternative to the equivalent of a NJ strip mall, the common areas of LGW, you can pay to enter a few different lounges in the North terminal. I believe they range in cost from ~18£ to 40£ per person. Holidayextras.co.uk has some good rates.

I'm leaving on AC from the North terminal. According to the *A Louge Finder website, they use the Aviance contracted lounge in the North terminal. But I'm in Premium Economy... so not sure if access is granted for *Gold?
