For 2 chargers you need DNO approval, not impossible but certainly not a given.
You can share a supply with a suitable charger config, Teslas does this, so that a pair of chsrgers will work individually but ensure their combined draw is no more than 32a (assuming your one charger is 32a). In general that’s enough for most people and overnight charging.

I've just had a second charger fitter.
Based on this experience, you will need a 100 amp fuse in your supply. Our 1930's house only had a 60 amp fuse initially so we first needed to get the electricity company to upgrade it.
Having done that, it was straight forward to get the second charger fitted. The installer though did need to notify the electricity supplier there would be increased load at the property.
One side point - our installer didn't double check the mains supply cables were fully tightened into the consumer unit (despite it being ticked on their certificate). When charging two cars, with an electric oven on, as well as several other appliances, the mains wire into our consumer unit started arcing as it wasn't properly tightened - it could have caused a serious fire if it hadn't been addressed quickly. So one to check for....

Most houses should have the 100amp fuse anyway and all charger installers have to notify energy suppliers/DNO. Based on this experience, you will need a 100 amp fuse in your supply. Our 1930's house only had a 60 amp fuse initially so we first needed to get the electricity company to upgrade it.

As said, some manufacturers fit a device which allows cars to charge one after the other or together but at half the power. Not all existing / older chargers can connect up this way though (probably as no-one thought this far ahead).
