Recommend a diesel generator.

broadgage

About 20 KVA, for domestic and home business standby use.  New preferred, but good, low hours used considered.

Weatherproof enclosure not needed as to be installed in a purpose built brick outbuilding.

Push button electric start required, not auto start.

Reliability, and user serviceable at least for minor services, are the most important features.

    In a flat I would recommend a decent sized UPS with an external battery for greatly extended run time.

    Suggested loads could include

    Gas central heating pump and controls, average 50 watts assuming 50% duty factor

    Fridge freezer average 50 watts assuming 40% duty factor

    Laptop PC, average 20 watts with use limited.

    Internet router, 5 watts continuous.

    Small high efficiency TV, average 50 watts.

    Lighting, installed load of 40 watts of LED lamps, average load 10 watts.

    Average load about 215 watts at line voltage, or allowing for losses in the UPS, about 10 amps from a 24 volt battery. A couple of 12 volt 100 amp hour batteries would give 12 hours run time.

    Extend run time by reducing the load, candles instead of electric lights, dry battery operated radio as main source of information instead of TV or internet. Use up perishables and turn fridge off.

    A large solar module to charge the UPS battery would help also.
