Not the foggiest mate. If it's not advertised on the site then probably not but a quick search of "Bosch free battery" suggests the offer may be wider than just the Bosch Professional site. You could try contacting the seller or do a similar search and have a look at sellers that are advertising the offer.
I've been eyeing up the GSR 18V-60 FC Professional. It's working out cheaper through a Bosch partner site. Would I still be able to get the free battery if I'm not purchasing from Bosch professional.com?
The code no longer works on anything.
This one when it's on special. Was recently £60. You'll need to keep an eye out but it does pop up from time to time with a good chunk off. https://www.amazon.co.uk/Bosch-Cordless-Combi-Lithium-Ion-Batteries/dp/B00L3XK06C/ref=sr_1_5?dchild=1&keywords=bosch+psb+1800&qid=1615926707&sr=8-5 Otherwise have a think on what cordless ecosystem you want to get into if you plan on getting several tools. You'll be gutted if you buy e.g. a Ryobi and then decide to get into e.g. Bosch as the batteries aren't interchangeable. I can recommend this Bosch Professional corded SDS also for more serious drilling or chiselling. I paid £65 a couple of years back but it's £90 even after discount on this deal & the same on Amazon. (It's much more manageable than the Titan beast from Screwfix which I also have - that's more of a demolition drill.) https://www.amazon.co.uk/Bosch-Professional-Corded-Rotary-Hammer/dp/B004FITJVE/ref=sr_1_3?dchild=1&keywords=Bosch+Professional+GBH+2-20&qid=1615927494&s=diy&sr=1-3 Seems to be a free battery offer on at the moment per the home page. If this works in conjunction with the discount then might be a deal or two to be had on cordless stuff. Otherwise looks expensive in general.
I think that's the body only price, £249 with batteries and case, the description at the top of the page is wrong....woould be a mega deal at that price
