I’ve just had confirmation from Newark/element 14 that my Raspberry PI will be delivered in the batch being shipped out June 29th.

The email also contained the following information:

As you may have heard, all the Raspberry Pi units require a CE (compliance tested) mark prior to distribution. We are pleased to report that this testing has been successful, following an accelerated application, jointly conducted by the Raspberry Pi Foundation and Newark element14. So once again, we thank you for your patience as you’ve waited for the delivery of your Raspberry Pi. We’ll be sure to keep you up to date as more news becomes available.

So that is great news, and means July will be spent working on the controller for the heating system. This leaves me with May and June to build the thermostats out.
