There is no legislation in the U.K. ,as far as I am aware,to stop you buying or owning Sulphuric acid.
Freely available from APC pure.

"It is now a criminal offence for members of the public to possess sulphuric acid above 15% concentration without a licence, with offenders facing a 2-year prison sentence and an unlimited fine."
Government introduces tough new measure to prevent acid attacks
The government has banned people possessing strong sulphuric acid without a valid reason as part of its drive to tackle acid attacks and violent crime.

My brother made a batch of "rocket candy" a few years ago, good fun.

Guess as long as you have a VAT number it isn’t an issue. Bought some last year ,but admittedly they would only deliver to a non residential address"It is now a criminal offence for members of the public to possess sulphuric acid above 15% concentration without a licence, with offenders facing a 2-year prison sentence and an unlimited fine."

at least you can water it down if you have some that is too concentrated
and remember the acid must be added to the water

I think that’s what they use it for, sprayed on from a garden type spray. We had one customer that took their year old Golf to a hand wash and ended up with a handprint on the front wing where a gloved hand was
Thanks everyone for the reply's, i now have a lot of good options!
Sorry, i really should have clarified what this was for:
I am thinking of using it to make a Copper(II) Chloride based etching solution, for use etching PCBs, so it needs to relatively pure, i don't want all sorts of junk in my etchant.

I've been involved in making printed circuit boards since the 1960's, and the use of hydrochloric acid for this task is quite unusual. For a very long time, ferric chloride solution was the way to go, and that's what I still use. That has largely being replaced now by what I think is a persulphate compound???
I'd guess the reason the the acid was never popular is that it is no more than a solution with water containing dissolved hydrogen chloride gas, and the latter is bad for everything, the fumes attacking body tissue and just about any and every metal with glee. I would never keep any hydrochloric acid in my workshop.

I’ve got some hydrochloric both medium strength and full nasty strength. Got it from a place that does bulk cleaning products if that’s any help?

Tell me more how long in the acid and how long and in what to neutarilese it.

This cupric chloride Jim's after is used by hobbyists because you can "regenerate" the solution by bubbling air though it and topping it off with a bit more HCL, someone on Instructables boldly claimed it's better than ferric chloride a few years ago and no one seems to have questioned it. Supposedly it's better because you never have to throw away old solution, you just bubble in air or add a splash of acid. Of course eventually you'll end up with a huge amount of etchant because you're never getting rid of the old copper ions, so it only makes sense for hobbyists doing very small quantities, doing it professionally you'll quickly have so much etchant that you'll still have to pay to dispose of it, so you may as well just use ferric chloride and not have to deal with rusty fumes.
