Fix extractor fan in bathroom & manage hot water for shower

£150

Nag's Head, Greater London

11th Apr 2026

The extractor fan for the bathroom doesn’t seem to be working which’s causing humidity to form in the adjacent bedroom (mould spores under mattress as a result). Need the extractor fan to be functional & to turn off with a timer. I’m not sure exactly where it’s located though. (Flat is currently tenanted- so sadly I can’t be there to assist). Hot water temperature needs to be adjusted in the shower… Tenants are saying that the water is scolding hot.
