You can also tow heavier trailers if combined weight of trailer and vehicle isn’t more than 3,500kg.

Easy to get confused. The old regs (pre 1997) allowed a trailer of up to 3500kg; the newer regs allow a train weight of 3500kg.

Just one further thought - before committing to any trailer it's essential to check the handbook for your towing vehicle to find the manufacturer's details of the maximum towing loads allowable for that vehicle. As an example my Peugoet estate's handbook quotes trailer at max 750 kg single axle unbraked, or 1500kg multi axle braked, subject to all up 'train weight' as mentioned by others previously.

Thanks, and yes indeed.  I only have a little Honda Jazz at present so I wasn't expecting it could do too much.  Checked the make and model and it looks like it can do the 750 kg single axle unbraked but that's about it.  So fine for now but I will probably need to look at something a little less urban in future
