Cost of fitting a bidet spray to the toilet

We got used to these on holiday and want one at home, it's just a little hose thing that connects near the loo as far as I can tell. Is it a quick job for a plumber, and roughly what would they charge? Also does it need its own valve?

I could do this 1 hours labour and the spray is around £25"

Hi, you would probably need to T off the cold water mains entering your WC. I would install an isolation valve as they can be known to produce minor leaks."

"Hello, I would charge from £90 total if tapping straight into the toilet’s cold water supply. it would be possible to get hot and cold water from the sink, but this would add additional costs. Most likely £140+
