Screwfix do seem now to be clearing out the non-Amd3 boards, sometimes at good prices for the internals.
For example, a few weeks ago, I bought a BG "12-Way Split Load Consumer Unit 80A RCD & 100A Switch" discounted down to £12. The housing itself is ----ed away, but the 80A RCD would have cost me £19 had I bought it on it's own.
