Ever walked into a steamy bathroom and wished the moisture would just disappear? A well‑placed bathroom fan does exactly that – it pulls damp air out, stops mold, and keeps the room fresh. Installing one yourself can save money and get the job done faster than waiting for a contractor. Below you’ll find the basics you need, from picking the right fan to wiring it safely.
First, decide how much airflow you need. Look for a fan rated in CFM (cubic feet per minute) – a good rule of thumb is 1 CFM per square foot of bathroom floor. So a 70‑sq‑ft bathroom needs around 70 CFM. Also check if the fan has a built‑in light or a humidity sensor; those features add convenience but cost a bit more. Make sure the model complies with UK building regulations and has the CE mark.
1. Gather tools and safety gear. You’ll need a drill, screwdrivers, a hacksaw (if you need to cut a hole), wire strippers, a voltage tester, and a ladder. Wear safety glasses and gloves.
2. Turn off the electricity. Switch off the circuit breaker for the bathroom or the specific lighting circuit. Use a voltage tester to confirm there’s no live current before you touch any wires.
3. Mark and cut the opening. Measure the fan’s housing template and trace it on the ceiling. Cut the hole with a saw, keeping the cut clean so the fan sits flush.
4. Wire the fan. Most bathroom fans run on a dedicated switched line from the light switch. Connect the live (brown) wire to the fan’s live terminal, the neutral (blue) to neutral, and the earth (green/yellow) to the metal housing. If your fan has a timer or humidity sensor, follow the manufacturer’s wiring diagram closely.
5. Secure the fan. Place the fan into the ceiling opening, screw it into the joists or mounting brackets provided. Make sure it’s level so the grille sits evenly.
6. Seal and finish. Apply a bead of silicone sealant around the fan’s edge to stop drafts. Snap on the grille, turn the power back on, and test the fan. It should run smoothly and pull air out as expected.
If you hit any snags – especially with wiring or if the bathroom has older wiring – it’s worth calling a Gas Safe or qualified electrician. A small mistake can lead to a blown fuse or, worse, an electrical hazard.
Once installed, keep the fan clean. Dust or grease can block airflow, reducing efficiency. A quick wipe‑down every few months keeps it humming quietly.
