Extractor fan installation in Epsom

Extractor fan installation across Epsom
We serve Epsom from our base in Banstead.
What happens on the day
The new fan occupies the opening already in that room. No new penetration is made in masonry, in roofing or in glazing. If the existing feed needs protection, the fan is connected through a fused spur and tried from its own switch. If that feed is too weak, the fan is left unconnected and a stronger feed is priced afterwards. A Georgian frontage near the High Street keeps the same limit. A fan the street would see is drawn against the council constraints before it is fixed.
- Keep the opening that existsThe replacement uses the hole that room was built with. A new penetration in masonry, roofing or glazing is refused, frontage or not.
- Protect the feed, then run itIf the existing feed needs it, the fan goes on a fused spur and is tried from its own switch. A feed that is too weak stops the job.
- A seen fan is drawn firstOn a Georgian frontage near the High Street, a fan the street would see is drawn against the council constraints before it is fixed. That does not allow a new penetration.

Can you cut a new opening?
No. The fan uses the opening that room already has. A new penetration in masonry, roofing or glazing is refused.
Does a Georgian frontage allow a new opening?
No. The limit stays. A fan the street would see is drawn against the council constraints first, and that drawing is not permission to cut.
What if the old feed is too small?
Work stops. The fan is not left connected to a feed that is too weak, and a stronger feed is priced afterwards.
How do you check it runs?
A fan that stays still is not left as finished. The check is from its own switch, through a fused spur or the existing feed.
Is a second fan on the same booking?
Only if it was listed. The opening on the booking is the one used. Another fan needs its own figure.
