It is a classy but small lounge. You cannot get in with a Priority Pass or Lounge Club card, so your only options are cash (the Plaza Premium booking page is here), showing an American Express Platinum or Centurion card or using DragonPass.
It turns out that DragonPass is running a few promos at the moment with selected partners that can get you into Plaza Premium Terminal 5 from just £15.
The best deal is £15 for O2 Priority customers (buy a £1 O2 SIM in your local newsagent and register it for O2 Priority if you don’t have one). An offer code is needed.
The Addison Lee offer does NOT require an offer code so this one is available to everyone. Register for an Addison Lee taxi account if you want to strictly play by the rules. Use code WELCOME15 when you sign up and you’ll get £15 off your first Addison Lee ride.
Please note that yesterday both the O2 and Addison Lee offer sites were being very buggy and there is no guarantee they will be working properly today. The Telegraph site was working OK.

Getting airport lounge access via a UK credit card
As a reminder, here are the three options to get FREE airport lounge access via a credit or charge card:
Two free Priority Pass cards (one for you, one for your supplementary Platinum cardholder, each admitting two – so a family of four gets in free) giving access to every lounge in the Priority Pass network – search it here. You also get access to Plaza Premium, Delta and Eurostar lounges. Our American Express Platinum review is here.
You get a Lounge Club card loaded with two free visits to any Lounge Club network lounge – see the list here. The list is slightly shorter than the Priority Pass list, but not by much. Additional visits are charged at £20 per person. You get two more free visits for every year you keep the card. No annual fee in Year 1. Full details are in our American Express Preferred Rewards Gold review here.
You get a free LoungeKey card allowing you access to any property in the LoungeKey network. Guests are charged at £20 although regular travellers will find it cheaper to pay £60 for a supplementary credit card (adults only, of course). The card has an annual fee of £195 and there are strict financial requirements to become a HSBC Premier customer. Full details are in my HSBC Premier World Elite Mastercard review.
