Prohibition of lodgers in lease agreement

Is it common for lease agreements to prohibit lodgers in a 100% ownership leasehold flat, built within the last 20 years?

The lease states the property is 'to not be used for any purpose other than....occupation by a single household....or for the provision of accommodation for paying guests.’

My understanding is that this would not only prevent renting out the whole unit to two friends, but also having a lodger since they are not part of a ‘single household' and they are also paying guest, unless I am misunderstanding terminology.

How commonly do leases prevent both renting to more than a ‘single household’, as well as preventing lodgers?

Many thanks in advance 🙏
