No. You have the right to one 20 minute unpaid rest break per working day, if you work over 6 hours. Your employer is able to designate those breaks at their discretion, though the break is only legally valid if it is uninterrupted for those 20 minutes, and you are able to take that break 'away from your work' - i.e not still sat on a forklift or whatever.
There's certain specific guidance on workers continuously operating in ways considered 'monotonous', but that is typically for people on production lines and the like, I would make the assumption your work is considered varied enough to not fall under this. The '5 minute break every hour' probably comes from HSAW regs on computer users, in that employers have to provide people using visual displays certain extra breaks (and the 5 mins per hour is a recommended example) or changes in work tasks, but it's not so much a law that they have to take those breaks, rather that they should be provided or catered for without question.
Basically, you get ten minutes more than is legally required, so well done you.
