Pros
Can be convenient if you are desperate to get a job, but do not expect too much
Cons
They don't look out for you. Customers can cancel even when you are right in front of their house. They don't give enough work. It's not reliable. The worst part is that customers can book a cleaning of a 3 bathroom 3 bedroom house (including kitchen an living room) and expect you to clean all that in 2 hours, and if you don't do it you'll get a bad review, which will affect the amount of customers/access to jobs outside of your area. Customers will expect you to do end of tenancy cleaning, in detail cleaning without warning. It's just BAD. Housekeep doesn't care. The training are 2 videos and they will ask you for around 56 pounds prior to signing up (they say that it's for the security check, though I had mine and they still charged me the same amount. They take 50% of all of your earnings and still, whenever they put the money in your account, they'll take another sum of money.
