BREL Report Requirements for Part L Photographic Evidence
Site managers need more than a folder of random photos. Building Control expects Part L photographic evidence that proves insulation, thermal bridging and air-tightness details were installed before they were covered.
Capture Part L EvidenceClear proof
Take wide and close-up shots so the plot, location and construction detail are obvious.
Traceable location
Tag every image to the plot, stage, room or elevation so the assessor can match evidence to the SAP/BREL file.
Before cover-up
Capture evidence before plasterboard, screed, cladding or finishes hide the Part L detail.
What photos should go into a BREL evidence pack?
Foundation and floor insulation before cover-up
External wall insulation continuity and cavity closer details
Roof, loft and sloping ceiling insulation before plasterboard
Thermal bridge details at lintels, sills, corners and party walls
Air-tightness details around service penetrations and junctions
Heating, ventilation and renewable system installation evidence
How to make Part L photographic evidence acceptable
Capture evidence by plot and stage, not by the date on your camera roll. Each photo should answer four questions: what plot is this, what detail is shown, when was it taken, and was the work visible before cover-up? If any of those answers are missing, the BREL report can become a time-consuming manual exercise.
ProPlot keeps Part L photographic evidence tied to the plot and inspection stage as it is captured. That makes it easier to build a clean handover pack for Building Control without searching through WhatsApp images, email attachments or unnamed site folders.
Turn site photos into a cleaner BREL workflow
Use ProPlot to capture GPS-tagged, stage-tagged evidence while the detail is still visible.
