Will let you know. My current doorbell like many UK is only 8V, so probably going to plead with a qualified spark at work to sort it for me. Something I could do but would rather someone I trust who owes me a favour to open up the CU
I took the jump myself - Got the Pro
I have no idea what to expect as I'm (hopefully) moving in on Friday, so don't have a clue what sort of wiring is down there
Fortunately, the fuse box is right next to the front door, so if I need to do a little re-jigging it should be fine
