Points to plan for in Derry
Access
Work is planned around tenants, often out of hours.
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.
Condensate
Blocked trays are a common cause of ceiling stains; regular cleaning prevents them.
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.
Premises we work in around Derry
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
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.
