Lomocovack's in France so might be using French or Jepp charts for the UK, hence his question!
The listed numbers on the CAA charts are as follows*:
D003, 004, 007A/B, 008/A/B, 012-014, 017, 021, 023 026, 031 Plymouth ops on +44 1752 557550
D006/A Culdrose Ops +44 1326 552201
D007 St Mawgan Ops +44 1637 872201
D036 Plymouth Mil +44 1752 557751
D123-126, 128 Stonehenge +44 1980 674710 or 674730
D130 AIS Heathrow +44 208 745 3451
* Got the above from the chart I keep at work, which is a couple of years old, so the above info is not necessarily current
If you are using Jepp/French chart by the way, watch out for airway N866 which is a Class A airway from (approx) NEDUL to ORTAC FL35+ and not shown on many charts that I've seen
