New cleaner wants to be paid more as house is bigger?

[Saltedbutter]

I agreed an hourly rate with a new cleaner prior to her coming and also an approximate amount of hours but left that quite open as I obviously don’t know her pace yet.
She is currently at my house and just messaged to say actually she’d like more money per hour as the house is bigger than she expected.
Surely she’ll still clean the same amount per hour as in a smaller house but just might be paid for a few more hours?
I’ve provided all products and the rate she now wants is more than my previous cleaner (who included her products).
AIBU?

£5 more per hour. So if working 3 or 4 hours in one house per week, that's £15 to £20 a week more. Times that by 48, and it's £960 a year.

OP paid it happily as she liked her cleaner.

She's paying double minimum wage.

Not sure why so many are assuming she's some evil person trying to exploit the staff. And I do hope those doing this always tip their Deliveroo drivers at least 20%.

She's not arguing that it may take more hours to clean the house than the cleaner expected from a phone discussion, in which case she needs to pay more overall. She's querying whether it's reasonable to charge more per hour for someone based on house size.

The hourly rate isn't generally set by house size. The number of hours required reflects that.
