with the immersion as a back-up if boiler fails. I don't like stuff like this, but it looks reasonably well done and you can't fail stuff cos you don't like it.
Now here's a poser for you:
House bombed during WW2 and rewired using conduit and cloth covered singles. Never been touched since, little old lady in the house. Lights have failed, turns out the lighting board has a fuse in Line and Neutral for the 2 lighting circuits. Replace blown fuse in the neutral and a few lamps and hey presto the lights are working again so she doesn't fall down the stairs in the dark. Now here comes the interesting bit, A.N.Other has been in tested the house and failed it all on grounds it needs a rewire, including the lights - failed to spot blown fuse it seems. Little old lady can't afford re-wire, so queation is, what do we do? Test results show cable and Zs values are all OK There's a few dodgy light swtches (also all original) so some maintenance work is needed. Alas no pictures as my phone battery was dead.
Option 1/ walk away and say re-wire or nothing
Option 2/ Replace boards to add MCBs and greater protection at minimal cost - something needs to be done as a new boiler is due to be fitted which will require new cct and MEB to gas and water to be fitted.
Option 3/ Just replace lighting CU (sockets have their own board) so cct for boiler can be added later
option4 / something else??
