Before you book in Stevenage
Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
Working hours
Most Stevenage businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
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.
