Most quantity surveyors will charge by the project and not by the hour/day. Therefore, there is no one-size-fits-all price. They usually offer a quote upon consultation and after they have all the information they need about the project. The exact price will depend on a number of factors, including:
The size and scale of the project
The surveyors credentials
Whether the quantity surveyor is part of a larger firm or not
Where you live (for example, Sussex quantity surveyors are likely to cost more than quantity surveyors in developing countries)
What services you require from the quantity surveyor
And several more factors
It’s a good idea to get a few different quotes and compare prices before settling on one. I hired Accel Consulting to help with a project last year and it cost a little over a thousand pound, but this is likely to vary dramatically based on your own requirements and circumstances.
