For anyone else who was out of the loop, this is a joke from the IT Crowd when (in the show) England was changing their emergency services numbers:

From today, dialing 999 won’t get you the emergency services. And that’s not the only thing that’s changing. Nicer ambulances, faster response times and better-looking drivers mean they’re not just the emergency services — they’re your emergency services. So, remember the new number: 0118 999 881 999 119 725… 3.

Edit: Edited for clarification that this was a joke in the show and England did not change their emergency services number IRL.
