Grab a multimeter from anyone you know who has one and measure battery voltage first thing, before putting the keys in the ignition.

I'd add morning, i.e. first thing in the morning.

I charged my battery last night and plugged it in the car before going to bed

Unless you go to bed very late the charging might not have been enough to fully charge the battery (if I had more confidence I might say, without knowing the details of times, voltages, etc., it probably wasn't enough, but as I haven't and don't, I won't). 🙂

 

The fact that you got some improvement possibly means the car has fuel and/or no punctures. 😁

Night time as in 7pm. Went to bed around 3am lol (night owl). Elderly naleighbours kept peeking in the window. Must've thought I was breaking into someone's car at that time.

Must be all those rain clouds over Cardiff  making the sky dark early.   I struggled to think of how many hours between 5pm and 3am but got to 10 in the end.  That'd be a reasonable pick up depending on how low and out of condition the battery is and the rate of the charger but it could still be well short of fully charged and will be slowly discharging when fitted to the vehicle depending on what's left running on the vehicle as it sits parked up.

 

As Wino has put take a reading first thing (in the morning, or perhaps afternoon for you(?), I used to be a bit of a night owl) and the meter could be useful for further investigations.  Modern cheap digital meters are fine for ballpark figures but give them some leeway for actual figures, always test the meter against something you know to be about right before every set of test readings (say a new 1.5V battery or another car battery) and don't do the test too quickly, hold for a few seconds to make sure the reading is reasonably steady.
