A fan in an annexe stays in the annexe and is not ducted through the house. 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. - Extractor fan installation: from £120 - 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. - Waterhouse Lane - Warren Drive - The Warren - Furze Hill - Woodland Way - Copthill Lane - Kingswood station - Lower Kingswood ## 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 exists The 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 fitting A 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 annexe The 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. ## Questions about a Kingswood fan ### 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. ## Other services in Kingswood - [Electrician in Kingswood](https://www.tmbelectrics.co.uk/electrician-kingswood): Electrician in Kingswood, Surrey (KT20).
