Do I need to survey all of my sites to comply with ESOS?

No. You must carry out site visits as part of your ESOS energy audit, but you don’t have to visit every site in your organisation.

You can instead take a sampling approach – whereby you split your portfolio into different building types, e.g. office, warehouse, retail etc. – and visit one of each. You can apply the findings to the rest of the sites that are identical or very similar.

Your lead assessor can help you determine a suitable site visit sampling approach. This is not prescribed in legislation and as such it is up to your organisation and lead assessor to agree this. You must however explain the approach you took in your evidence pack.
