Batteries need charging, and if there was any old electric
installation I'd hope that it had been replaced by modern stuff as
one of the first things they did, if only so that they could use
power tools for all the repairs and restoration.

I think buildings of 'that age' would have had no electricity or gas
when built. This one has (it says) been uninhabited for over a
century so it's likely that no gas or electricity installation had
been made at all. It does seem to have some indoor plumbing though.

If the wiring in the walls was the old cloth-covered stuff, you could
probably charge an iPad by induction...

WWI wiring (ie what would be the latest likely installation if the place
has been unoccupied for 100 years) might well be un-insulated 'knob and
tube' intended for whatever DC voltage the local power station
(Shoreditch?) could have got that far - likely less than 100 volts.
(London's original power companies were very local, so DC was fine for
them).

I thought it was the other way around. Power supplies were DC and
could only service local consumers. Tesla had yet to win his war with
Edison.

The Edison-Tesla war was a US Civil War and more legend than fact, I
don't believe that true impact of that was felt until in the UK until
it was decided.

Umm: err ...?

Also, Tesla was more of a catalyst in a war between
Edison and Westinghouse.

Tesla was the technical brain behind Westinghouse.
Westinghouse was the financial muscle.

That said a check of the timeline of the UK
electricity supply has the following chronological events:

1882, the Electric Lighting Act 1882 allowed the setting up of supply
systems by persons, companies or local authorities.
1888, amendment to the 1882 Act making the setting up of a supply
company easier.
1891, London Electric Supply Corporation (LESCo) opened Deptford Power
Station, UK's first AC power system.
1901, Newcastle-On-Tyne Electric Supply Company (NESCo) opened Neptune
Bank Power Station, the first in the UK to supply three-phase electric
power.

I couldn't find any history of extensive UK domestic DC electric supply
prior to that timeline, though I am sure there had to be some sort of
impact of Faraday's work and the advent of the industrial revolution.
It is worth noting that Tesla only started working for Edison in 1884
and quit in 1886. By 1888 Edison had lost the AC-DC power transmission
war to Westinghouse, and the dirrection in Europe was toward AC
generation/transmission.

AC was the only way to go. The technical limitations of DC meant that
it should have been a non-starter.

DC was better for small scale stuff and easir and cheaper.
Just think how much a problem it'd be to use AC as power to your camera.

Just think how difficult it would be to supply a steel mill power if
you only had DC.

Threre's some evidence that DC was used by the Egyptians if not earlier civerlisations had DC.
