Bats in the belfry, windows are jammed - London flat renting, deposits & landlords

I thought agents coulnd't charge fees now? But I see this on a listing:

Agents Note - Excellent references will be required by anyone renting through Bychoice

• A minimum deposit of one & a half months rent is required (may be increased in certain circumstances)
  
• Referencing & administration fees apply, £215 for a single applicant & £60 extra per applicant/guarantor thereafter
  
• A check out fee of £60 is charged at the end of your tenancy per property
