In England, ventilation is covered by Part F of the Building Regulations and its guidance, Approved Document F (2021 edition). For homes, it sets minimum extract rates such as 15 litres a second for a bathroom and 30 or 60 for a kitchen, and expects mechanical systems to be airflow-tested.
Questions from Carshalton
What is the price of a ventilation repair in Carshalton?

Is it worth repairing an old extractor fan?
Usually not for a basic bathroom fan, because a new fan costs little more than the repair. MVHR, PIV and commercial fans are often worth repairing.
Why is my extractor fan humming but not spinning?
A humming fan that does not spin often has a failed capacitor, seized bearing or obstruction. It should be switched off until repaired.
