I bought a diesel generator for £100 from eBay in the spring. Used it a couple of times already. It will not run the whole house for example with the washing machine tumble dryer TV etc on you cannot do the vacuuming but it is pretty good. It is noisy but our nearest neighbours are far enough away to not worry. Oh and I can run it on red or I can doctor some heating oil with a bit of engine oil to make it lubricate like diesel so not too expensive to run. I suppose I could weld up a better exhaust system. So power cuts will not hold too much dread for us.
The only time I’ve used my Phone Torch this year is when I open the dark cupboard to read my electricity meter!
Recently, I’ve been reading my meter more often than I used to!
