- Any area that has a headroom that is below 1.5m (excluding the area beneath a staircase)

How to perform an internal area search lookup of a property
Using our simple calculator, just enter the postcode of your property, or a property you are interested in purchasing, and let our bespoke software do the rest.
The software uses Energy Performance Certificate data, provided by the Ministry for Communities, Housing & Local Government. Any property that has been sold in the last decade is likely to be included in the database.
Once you have typed in your postcode and hit the search button, all properties relating to that postcode will be listed. If the search return contains a lot of properties, then you can use the filter options to narrow down the list.
Please note that if an individual property has multiple search results, then you should check the date of each. An increase in internal area may suggest that the property has been extended during this time.
