Went to the Post Office today and a new Thermostat for the underfloor heating had been delivered!

Took the old one off (yellowed, faded, no Interwebz) but it had been squeezed into the back box with one retaining screw...
Fitted the new thermostat (WiFi, all singing all dancing

) but the second retaining clip snapped off when I tried to straighten it...

Now I'm into a nightmare back box replacement... Given that I have another seven thermostats to replace I wasn't happy...

But BEHOLD! The Interwebz reveal that a back box repair clip is available - now on order from Amazon!
I love the Interwebz...
