\Be careful.
It's easy to say increase it but no one knows your client, you do.
I will be absorbing it as they have another location with different cleaners who are cheaper than me, if I increase I'll lose it.
Don't forget though, this living wage is just the start, it'll be going up to £9-10 pounds over the next 4 years, I feel in April either lots of things will increase in price or staff will be laid off, or both.
