Part L Compliance

Seamless compliance with Part L Building Regulations, required by law.


In June 2022, the UK government introduced new regulations aiming to reduce the CO2 emissions of new dwellings and commercial buildings.

One of the new requirements is to provide photographic evidence of insulation installed during the project. Specifically, the photos must be of high quality, show enough detail and be geotagged to verify the location the photos were taken.

Geotagged photos

Geotagged photos

Geotagging photos can be a challenging process on a project with different people, different companies and varying hardware to take the photos. Photos need to be tagged correctly with exact latitude and longitude coordinates, and time and date stamps, otherwise they may be rejected by assessors.

The Fonn app allows users to capture all images of the build phase and automatically geotag them, removing the need to process photo evidence manually which can be open to human error.

Part L Reports

Part L reports

The new regulations are subject to assessment under the new SAP10 scheme and your SAP assessor will need to see the appropriate documentation in order to release your energy performance certificate (EPC). Without an EPC, selling the house could be delayed or denied.

With Fonn, you can access auto-generated reports on-demand ensuring projects are not delayed while your teams scramble to produce and send reports to be audited. This also helps avoid manual errors that can creep in during paperwork.
