You asked
I have seen there is dataset showing households with basements and would like to request this data.
We said
Thank you for your request.
We used to have a question in the census asking about the "lowest floor level" in households. This was last asked in 2001. Data about houses with basements from 2001 are available on the NOMIS website.
Unfortunately, we do not hold any more recent data on this topic, as this was not asked in the 2011 Census or Census 2021.
The Ministry for Housing Communities and Local Government (MHCLG) may hold data that will assist with your question. They can be contacted at FOI@communities.gov.uk.
