Building Regulations
New or altered ventilation in Scotland must meet Section 3 of the Scottish building standards. We design to it and hand over the commissioning records.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Noise
Fans and grilles are selected and attenuated to keep noise down.
Conservation areas
Historic streets and listed buildings in and around Annan are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
