OK, so my hand is still broken :-(
And last week we had a water leak (a slow one, but enough that the kitchen cupboard was full of water).
So you’d hope that that was the end of it. But no. Last night, the power went off. Why? The RCD on our distribution board had cut in, because—joy of joys—the central heating boiler has developed an earth fault. As a result, it’s currently switched off, so no heating for us.
