I used to work in a small recruitment office in Bristol, and we didn’t really think much about cleaning quality at first. The place was just 'fine', but people often complained about feeling tired in the space. Later we switched to a professional cleaning service, and over a few weeks the atmosphere noticeably changed. Desks felt fresher, common areas stayed organised, and even the break room started to feel more comfortable. What surprised me most was how employees reacted—people started staying longer in the office and seemed more relaxed during the day. We didn’t change anything else in that period, so the improvement was pretty clearly linked to the cleaning routine. It became easier for everyone to focus, and even small frustrations about the workspace seemed to fade away time.
