Dear [Landlord],

Daylight if you can. Step back so the affected area plus a hand's width of dry wall fits in frame.
Stitchbloc writes it for you. Polite, dated, evidenced, and worded so it ages well, useful three weeks later when nothing's been done, and useful three years later if you ever need it.

Hi Tony,
I'm writing about the damp in the bathroom at flat 3B, 14 Bedford Mews. I first reported this on 7 May 2026 (ref SN-2041). It has worsened since then.
The preliminary photo assessment flagged the visible signs as needing urgent attention and highlighted a mould-like region (about 0.42 m²) on the ceiling near the extractor fan.
Please acknowledge receipt, arrange a physical inspection and send me a written update with your proposed date and next steps.
Happy to provide access. Please confirm receipt and your proposed date.
Maya

Do not wait for a photo assessment. If someone has breathing difficulties or symptoms you are worried about, contact their GP or NHS 111; call 999 in an emergency. Report the damp or mould to your landlord promptly and ask for a physical inspection. Stitchbloc is not a medical service and cannot decide whether a home is safe.
