Location? What is real name + location of church where J.E. meets Patch?

What is the name of the church where they filmed the scene where Johnny E. & Patch (the 'Q' counterpart!: played by Tim McInnerny) meet up, and they accuse each other of being the double agent?

For some reason I think it might be St Paul's Church (aka 'The Actors Church') which is in Covent Garden In England. But I can find nothing at Google to confirm this.
