What to think about in Horsham

Diversity

Not every room peaks at once; good design accounts for diversity so central plant is not oversized.

Access and parking

Town-centre jobs in Horsham 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.

Noise

Outdoor unit noise is designed in from the start, not fixed afterwards.

Leased premises

If your Horsham 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.
