Who installs extractor fans in bathrooms and kitchens?

Extractor fans should be fitted by a qualified electrician or ventilation engineer. They’ll handle wiring, venting, and safety checks to make sure your fan works efficiently and is compliant with Part P electrical safety regulations.

Do I need an electrician to fit an extractor fan?

Yes. Bathrooms and kitchens are both special locations under UK electrical safety rules. Any new wiring or connection to a circuit must be carried out or certified by a registered electrician to ensure it’s safe and compliant.

How much does extractor fan installation cost in the UK?

Here are some average extractor fan installation costs:

• New extractor fan (including any new wiring needed) – £300
• Replacing an existing unit – £200
• Kitchen extractor fan – £60

What’s the difference between a ventilation fan and an extractor fan?

Both improve air quality, but they work slightly differently:

• Extractor fans remove stale, humid, or greasy air from a specific room — like a kitchen or bathroom — and usually vent it outside

• Ventilation fans help circulate fresh air throughout a building, sometimes bringing air in from outdoors as well as pushing old air out

In short, extractor fans target problem areas (like steam in bathrooms), while ventilation fans manage overall airflow to keep your home comfortable and healthy.

Is it illegal not to have an extractor fan in a bathroom?

If your bathroom doesn’t have a window, UK Building Regulations require mechanical ventilation – usually through an extractor fan. Even if you have a window, fitting a fan helps control condensation and improve air quality.

Is it illegal not to have an extractor fan in a kitchen in the UK?

UK Building Regulations (Part F) require adequate ventilation in all kitchens to remove moisture and cooking fumes. This can be achieved with either:

• A mechanical extractor fan that vents outside, or
• A recirculating cooker hood combined with a window or other natural ventilation

So, while you don’t have to install an extractor fan by law, you must ensure your kitchen has proper airflow to meet ventilation standards and prevent damp or mould.
