What to think about in Larne
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 Larne 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.
Noise
Fans and grilles are selected and attenuated to keep noise down.
Access and parking
Town-centre jobs in Larne often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
