Local points to consider
Building Regulations
New or altered ventilation in Northern Ireland must meet Technical Booklet K. We design to it and hand over the commissioning records.
Conservation areas
Historic streets and listed buildings in and around County Antrim are more likely to need planning permission for outdoor units on visible elevations. We check with the council's planning service before work is booked.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Working hours
Most County Antrim businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
