Who Fits Extractor Fans? Your Quick Install Guide

Got a stale kitchen or a bathroom that feels like a sauna? An extractor fan can clear the air fast. But who should actually fit it? You might think it’s easy, but there are a few things to check before grabbing a screwdriver.

DIY or Not? Knowing Your Limits

If the fan is a simple wall‑mounted unit and you have basic tools, you can probably do it yourself. Most DIY fans come with a step‑by‑step sheet that covers mounting, wiring, and sealing the vent. You’ll need a drill, a screwdriver, a wire stripper, and a voltage tester. The biggest rule is to turn off the circuit at the breaker before you touch any wires. If you’re comfortable working with electricity and the fan’s power rating matches your home’s supply, go ahead.

But if the fan requires hard‑wired connection to a ceiling light, a complex duct run, or you’re dealing with a high‑power kitchen hood, it’s safer to call a qualified electrician. Incorrect wiring can trip breakers, cause sparks, or even start a fire. An electrician also ensures the work meets local building codes, which can matter for insurance.

When to Call a Professional

Here are the top situations where you should hire a pro:

  • The fan needs to be connected to a dedicated circuit.
  • You have to cut through plaster, brick, or metal ducts.
  • There’s limited space and you need to modify existing venting.
  • You’re not comfortable turning off the main power.

Professional installers can also advise on the best fan size for your space. A fan that’s too small won’t clear moisture, while an oversized one can be noisy and waste electricity.

Costs vary, but a basic install by an electrician usually runs between £80 and £150, including labour and any required wiring parts. It’s worth getting a quote first, especially if you have a modern, high‑speed hood that might need a stronger circuit.

Whether you DIY or hire an electrician, finish the job by sealing the vent opening with silicone to keep drafts out. Test the fan after the power is restored – it should run smoothly with no unusual humming.

So, who fits extractor fans? If you’re handy with tools and the job is straightforward, you can do it yourself. For anything involving hard wiring, ductwork, or code compliance, call a qualified electrician. Either way, you’ll enjoy fresher air and a drier home in no time.
