Why not a diesel generator with a bit of ooomph?
Example. Honda 10KW, electic start, 230/115v automatic operation, 65dba @ 7m 20hp engine, c.£8000+vat [+ Possible heating operation from the cooling system].
Business use cuts the VAT!
'Red' diesel at £0.30p litre = 3p/kwh gross = 7.5p/kwh assuming normal diesel efficiency, plus the capital depreciation and servicing costs.
Say he got 500,000 kwh over 10 years, and annual sevices cost £100, that would make his electricity about 9.5p/kwh all in. If he nursed the genny for 15 years, he'd do even better. Assumes zero value at end of period.
With no standing charge, and a bit of free heating, that would come out better than the poco! There are cheaper gen-sets on the market. Batteries? in 2-3 years he'd be buying a new set.

ps. Or a Honda 4kw model, £4250+ vat, same spec as above. A bit small, but with his present lifestyle it might serve.
