Reasonable price for end of tenancy deep clean, studio flat in London?

[AbsentmindedWoman]

Negotiating cleaning fee to be taken from deposit, waiting for the estate agent to come back with a quote. What is a fair price? It's zone 2.

I have an end of tenancy cleaning company ( not in London but SE). We’d charge around £180-£200 which includes the oven and professional deep clean of carpets.

Thank you, that is helpful as a guide!

I paid £140 for our zone 2 studio flat when we moved out 1.5 years ago.
