Points to plan for in Derry
Switch it off
If water is coming through a ceiling or the unit is tripping, switch it off at the isolator until it is checked.
Access and parking
Town-centre jobs in Derry 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.
Repeat failures
If a system has failed several times, we compare the cost of repair against replacement.
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.
