We are based every 4 weeks with our regular work, occasionally it could be 5 or 6 weeks in terms of our holiday as we would let our customer know eventually. So we clean windows for our regular clients basically every month. We would always make sure to follow the health and safety guidance and be aware of any potential risk for our customers and ourselves. As we come regularly to those jobs, we are pretty experienced in that area, so it reduce the possibility of any risk.
