Cardiff and surrounding areas

In Cardiff, outdoor unit positions are often the deciding factor: a rear flat roof or yard is usually straightforward, while a front elevation may need landlord or planning consent first.
For servicing and repairs in Cardiff, roof and high-level access is planned in advance, so the visit is not wasted waiting for a tower or a key.

Points to plan for in Cardiff
Leased premises
If your Cardiff 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.
Working hours
Most Cardiff businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
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.
Compliance in Wales: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
