Extractor fan installation in Kingswood
An extractor fan in Kingswood uses an opening the room already has. A fan in an annexe stays in the annexe, on the board that feeds that building.

What a Kingswood fan includes
We price the fan that was named, the path the air already has out of the room, and a test of the circuit that will feed it. Cutting a new hole is a separate figure, and only when the room has no opening. An annexe fan is not priced as if it were in the house.
From £120
Included
- Removing an existing extractor fan
- Fitting the new extractor fan
- Wiring to a suitable supply or fused spur, the switched fused connection beside the fan
- Testing that the fan runs from its switch
- Clearing the work area when the job is finished
Ways to pay


- Pay by bank
- Bank transfer
- If the circuit cannot feed the fan, we record that limit and cut nothing.
- Painting the room once the fan is fitted is not part of this figure.
- The fan model is the one named before the day.
Extractor fan installation across Kingswood
We serve Kingswood from our base in Banstead.
What happens on the day
Air leaves by an opening the room already has. A fresh hole is described only when that room has no way out. In a Costain house the fan circuit is tested against the wiring that is there, including original wiring under an addition. A fan fitted in an annexe stays in the annexe. Houses on Woodland Way that want extra circuits do not have the fan counted as one of those circuits.
- Use an opening that existsThe duct uses a way out the Kingswood building already has. If another way out exists, a fresh hole is refused and that refusal is written down.
- Test the circuit before fittingA fan goes on original wiring under a Costain addition only after a pass. A lit lamp is not unused capacity. A fail means we name a separate circuit.
- Keep an annexe fan in the annexeThe duct and the fan stay in the building being fitted. A house ceiling is not used as a path for an annexe, and the garage is not used as a duct.

Will you cut a new hole?
Not where the air can already leave the room. A fresh hole is described only when no opening exists, and it is costed before anyone cuts.
Can the fan share original Costain wiring?
Only after that circuit passes for the fan. A lamp that already lights does not settle it. On a fail, a separate circuit is named before any fan goes in.
Does an annexe fan use the house ceiling?
No. The annexe exhausts through the annexe. A board out there is not a path for the air, and the house ceiling is left alone.
Is the fan itself included?
Yes if that model was chosen ahead of arrival. After the duct size is fixed, another model is costed before it is put in.
Is this one of the extra circuits at Woodland Way?
No. A fan is a fan. Extra circuits those newer houses want are a socket or circuit job, not a duct through an existing opening.
