Cottage bedroom floor joists need strengthening

[Janddcrisp]

The bedroom floor joists in our old cottage need strengthening, the floor is very bouncy and noisy. Currently there’s a hardboard floor down which we will either replace with same or a wood floor.
My question is, what kind of tradesman do I need to do this? Wooden floor installers don’t seem to advertise this as a service.
Thank you.

Joiner (carpenter in south of Englsnd.....), because the work is structural and involves timber. The hardboard is merely a covering over the original floor planks and has been installed either to minimise draughts or to cover bodged repair work (normally by a plumber or an electrician), or possibly both. It needs to come up and the flooring beneath will then need to be lifted as well to see what the issues are. The flooring may need to be replaced as old floor boards can be impossible to get up without splitting them due to age and brittleness

Once the floor joists are revealed it will be possible to determined if the floor can be stiffened by adding solid strutting, or whether the joists need to be doubled up ("sistered").

We have joiners down here, different trades.

Actually, in the north the word commonly used for what you call a "carpenter" is actually "joiner". I'm old enough to actually be a carpenter and joiner - we trained people on both site and bench up.until about 20 years back AFAIK

In terms of different trades, even that isn't strictly true, as even in the days of the trade guilds there was a lot of cross-over between the two disciplines (and a lot of disputes over who could do what)
