Commercial leases in London move quickly, and the details can get fuzzy even faster. One person remembers a mark on the wall, another swears it appeared after move-in, and suddenly, you're debating history instead of solving a problem. A clear baseline record keeps that from happening. It helps landlords and tenants stay fair, especially when teams change or works overlap. I'm a fan of anything that replaces guesswork with evidence, because it saves time and stress for everyone.
