How to get rid of ants?

All youtube videos give you the sugar and borax mixture but you can not buy borax in the UK.

Where abouts are the ants - house or garden?
If in the house, just keep everywhere, spotlessly, clean and use that Nippon type stuff they take back to the nests. Dethlac spray is pet safe and stops them from wandering too far afield as well.
The ones currently digging up my lawn. I’m just leaving them be.

In the garden and getting into my plant pots.

Where they will do no harm so no need for chemical warfare.

They are doing harm as they are working with aphids and destroying my rhubarb.

So it’s aphids that are causing the issue, the ants are just taking advantage of the aphids, still no need for chemicals killing the ants won’t get rid of the aphids, just hit the aphids with your garden hose.

I have used a soapy water solution in an old spray bottle, seems to be working.

cheap washing up liquid in the cracks where they come from does the trick.

And put the pots on 'feet'.

Stones or brick bits will do just to get them off the ground so the ants won't nest there.

Ants herd the aphids together on plants, keeping them captive by releasing chemicals through their feet that subdue the aphids to ensure they remain under their control. They 'milk' the aphids by stroking their abdomen to coax them to secrete their honeydew.

In the one pot that seems to attract ants (and aphids), I use nippon in a plastic device designed to enable the use of liquid feed outdoors - I refill it when it becomes empty.
