Things to check in Lerwick
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.
Working hours
Most Lerwick businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Conservation areas
Historic streets and listed buildings in and around Lerwick are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
