I need to replace the extractor fans in 2 bathrooms. I'm planning on replacing them with units with a humidistat. Can anyone recommend what brand/model to get, and who to use to get them fitted.
 
Vent-Axia and Xpelair are decent brands. The Vent-Axia Silent Fan range are pricey, but quiet!

If the existing ones are connected to standard 100mm flexible or rigid ducting, replacing is a simple enough DIY job.

I was wondering whether switching to a fan with a humidistat would complicate the wiring. The fan in the en-suite currently turns on and off with the light switch. There is a second switch that only impacts the fan, but it needs the light switch on for the fan to turn on. I'd want that to change to coming on with the light switch, but staying on until the humidity is low enough.
 
It should be ok sounds like there are 3 wires to the fan, neutral, permanent live from the dedicated isolator switch and a switched live from the light.
 
Ah, that could be an issue. To have the fan run on for a time after the light is switched off or until humidity drops below a certain level does require a permanent live connection. If the current set up requires the light switch to be on and the fan doesn't run-on for a period after the light is switched off, you likely don't have a permanent live. The second switch that allows you to turn the fan on/off when the light switch is on may just wired inline from that feed from the switch.

Simple enough job for an electrician to modify.

I have one of these fitted for about four years and have found it excellent. It's very quiet, even on it's most powerful setting it's more airflow you can hear as opposed to the fan motor or blades.

Very important aspect especially if anyone is trying to sleep anywhere nearby. Down through the years we have had some fierce noisy fans.

Yep, and I'd bet that's why the house here had another switch wired in to allow them disable a fan that was originally controlled by the light switch so it didn't disrupt people at night.

Yes, if memory serves me well one of the fans that we had was operated by a light switch. If someone hit the wrong switch there was a 15 minute timer on it which during the night was a right pain.
