Before you book in Hoddesdon
Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
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.
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
Leased premises
If your Hoddesdon 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.
