Things to check in County Down
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.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Working hours
Most County Down businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Conservation areas
Historic streets and listed buildings in and around County Down 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.
Two rules matter for most businesses in Northern Ireland: EU F-gas rules that apply in Northern Ireland (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
