I want to set up a bakery in my single garage (500x245cm). Single phase, 100A overhead supply. Existing single cable (not sure if it’s 6mm or 10mm) already into garage taken off a 32A MCB ‘sockets’ circuit. Ideally, I’d like to install about 5 built in electric ovens, probably 16A rated anything between 3.2 and 3.8kw max power per appliance. Ovens will be in use during the early hours/night time when only other power consumption in the adjacent house is fridge/freezer/occasional light. Is this doable? And if so, how?! Thanks in advance for any advice & guidance..

Without getting too technical, it is as you say "do able" but it's not feasible.
Your first step should be your local council to see if you are allowed to use your garage for a commercial bakery.

Then you need to get an electrician to visit site, your garage/bakery will probably need its own supply, but it's not possible to see from this end of a keyboard.

I suspect this really is pie in the sky.

In the main ovens use full power to heat up, then they switch on/off to maintain the heat, it could be arranged that they load share i.e. a set up were only 3 can turn on at any one time, so total amps is reduced.

Although would still be taking the same energy.

So yes possible, but you should be telling the DNO with a load like that, and also the council with change of use, you may get away with it, but you need to be aware if some one complains you could be shut down, all it takes is for one delivery driver to annoy a neighbour, I had a guy running a business opposite my mothers house, I was willing to turn a blind eye, until parking of delivery vehicles blocked my car in the drive, it got very close to my putting in a complaint.

However I take my car to some ones house for repairs and service and there is no problem as no neighbours to upset.
