Yes, Ringi, techs I used to work with who just dispensed are now ACTs and checking scripts, one does a private service for ear wax removal which is incredibly lucrative at around £60 for both ears, as the NHS doesn't seem to offer this in many areas now. Something else that GPs don't do anymore.
Another tech is trained to do flu jabs because the pharmacist had a needle phobia.
So yes,the world of pharmacy techs is expanding and they are pushing close to £30k a year now if they are full time and get a slight premium above minimum wage if they do roles that the pharmacist previously did. I know one checking tech on £16/hr which is pretty significant if you consider what you mentioned re: time line and the pharmacist is only on £22/23, with the debt and later start in work as you mention.
The only problem is there is no money left after funding this, and ever increasing minimum wages that there is no money left over to give the poor pharmacist a pay rise, as I think SarahH has touched on in her posts, with wages still stuck around 2010/12 levels. A quick look on something like LocateAlocum will show this.
