Hello and welcome to CG!
As I am half a world away, I can't speak as to what machines are available to you in London but I can offer that I very much doubt that you would want to run a machine off batteries, the current draw would be huge and you would need a truck to haul around your "battery pack". Neither would you likely want to use a lever machine in a commercial operation, they are just not made for the kind of service and speed that you will require when there are 8 people lined up for drinks. In a commercial situation, you WILL need a commercial machine, if for nothing else than the health certs that come with commercial machines and that DO NOT come with home duty machines.
Most machines that run on gas, I think use LPG and as that fuel is very inexpensive, unless you have some venting issues with the exhaust gasses in a confined space, I would expect that you would use gas all the time.
There are a few members that should be close to you and may be able to help you with local vendors, or at least ones that are on the same land mass as yourself.
In real life, my name is Wayne P. Anything I post is personal opinion and is only worth as much as anyone else's personal opinion. YMMV!
Feed the newbs, starve the trolls and above all enjoy what you drink!

a lever machine might work, you don't really have to have power and they used to make them with gas (propane) hook ups. you may be able to order a lever machine that is outfitted for propane. you still have the problem of filling the boiler though, you'll need to manually fill the boiler (with a pressurized water bottle), or figure out a way to hook up a flo-jet (power or maybe batteries?), so you don't have to mess around filling up the boiler as you use the machine....we used to have a gorgeous 1980 lever here at Intelli that had the gas hook ups.

Commercial levers are plenty fast, and have been since around 1945. The reasons to prefer electric pump over lever aren't speed. 25-35 seconds is still the goal; taking a tenth of a second to push a button vs 2 seconds to pull a lever isn't going to significantly change the line of waiting people. A spring lever will automatically stop the shot, not unlike a full-auto, so go ahead and concentrate on that milk.
Home lever machines are out of the question, because they're not available in gas, among other problems. (Correct me if I'm wrong, of course, but I haven't seen any current gas-fired home machines.)
I know we were oohing and ahhing on the style of the Futurmat Palanca a while back on a different forum; it's available in gas.
From what I understand, the Rancilio Classe 6 series is available with gas heat; I'm not sure if that's only available for manual (hand) pump models, however.
Astoria machines have been already mentioned.

Izzo Pompei lever (1 - 4 group) machines are available in electric or gas. I just spent a week in Napoli and these machines seem to be the standard in the coffee bars. Check out there web site - having one of these would distinguish you from the pack

Hi guys having an issue with my Ellise Al, 2group (Bezzera) gas powered machine. I have hooked up the machine with water supply and gas supply according to inststructions. But regarding to gas heating element, I have some difficulties. the flame is blue and bride as manual saying, but after 30 minutes of heating process the pressure on the relevant gauge does not change. (it stays on 0 no change at all....) and after that time - aproximately 30 mins the flame goes down assume due to termostat regulation. but the pressure on the gague has 0 value. i was thinking that the flame is too low but whole machine is hot. just the pressure gague is not going to chage for desire pressure. i beleive that gas heating system is able to heat the machine on its own and we do not need to trun on the electrical system.
