Things to check in Derry
Northern Ireland
Systems over 12 kW must be inspected by an accredited energy assessor within five years of installation and then every five years, with the report lodged on the register; the penalty is £300.
Leased premises
If your Derry premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Not an F-gas check
A TM44 inspection is about energy efficiency. It does not replace F-gas leak checks or servicing.
Conservation areas
Historic streets and listed buildings in and around Derry 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.
Who we work with in Derry
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
In Northern Ireland, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under EU F-gas rules that apply in Northern Ireland, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
