Cooking smells from neighbours: ventilation, causes and practical agreements
The smell of baking, roasting or frying can enter your home through a window, crevice or ventilation duct. What can you investigate together and what adjustments can help?
Smelling food from time to time is part of living close together. If the smell often persists for a long time or if you cannot use a room comfortably because of it, it makes sense to investigate the cause. Start with what you perceive and leave room for a technical cause.
This guide applies to England.
When do cooking smells become a problem?
Note when and where you notice the smell, how long it lasts and which windows or vents are open. Does it arrive from outside, a vent or the shared corridor? Compare ordinary conditions without turning off necessary ventilation.
Also describe the result. Maybe you keep closing your bedroom window while eating, the smell stays in textiles or you avoid a room. Avoid judging what someone is cooking. The conversation is about the spread and duration of the smell, not about someone’s eating habits or background.
What causes can you investigate together?
A discharge point near your window, insufficient extraction or a problem with air flows can require attention. You can’t tell which system is malfunctioning from the smell alone. Ask if the neighbour notices the same and if the problem started after a renovation, new hood or maintenance.
Ask the landlord or managing agent to inspect shared ducts. Avoid closing vents or changing a shared extraction system.
How do you discuss it calmly?
Make it specific
Choose a quiet time and give one or two examples. Ask whether the neighbour will help identify the route. A brief agreed check can be more useful than debating how strong the smell is.
A calm opening
“Over the last week, cooking smells have regularly entered our bedroom around mealtimes. They seem to come through the vent, but I’m not sure. Could we ask whether the extraction or airflow needs checking?”
Choose a small first step
For example, the owner checks the extractor instructions and filters while you note the affected room and times. Agree when to review the result and who will arrange an inspection if it continues.
What tools and adjustments can help?
Use extraction appropriately
Check the extractor’s instructions and ask for a technical inspection if it is not working effectively.
Checking the filters
Check whether the hood extracts outdoors or recirculates air, and what filter maintenance its manufacturer requires. A replacement filter does not guarantee that smells travelling between homes will disappear.
Evaluating the route of the air
An installer can check extract ducts, replacement air and shared ventilation. Let the landlord or managing agent authorise changes. Do not reroute ducts or alter a wall outlet yourself.
Keep your home ventilated
Keep essential ventilation working. If odours enter through it, ask for a technical remedy that maintains adequate airflow.
Which rules apply in England?
Domestic cooking smells and fumes from business premises do not follow exactly the same statutory-nuisance provisions. Ask the landlord about shared extraction and the council’s environmental health team which route applies to the source you have identified.
What if the smell keeps coming back?
Record times, rooms and the suspected route. Request an inspection before altering ventilation.

Keep the next step manageable
Use the free incident diary for a few representative observations, any agreement and improvements. If you need outside help, see Who can help. State what happened, what you have tried and what you are asking the recipient to do. You do not have to keep approaching the neighbour if contact feels unsafe.
