Commercial Heating, Ventilation and Air Conditioning Contractors in Southampton
Boiler house refurbishment, heating, ventilation, air conditioning and maintenance for NHS community hospitals and healthcare buildings in Southampton.

Preou in Southampton
Near Southampton we were main contractor for the complete mechanical and electrical upgrade of Ashurst Hospital.
Ashurst Hospital is part of University Hospital Southampton NHS Foundation Trust. Our engineers travel from Billericay, about 98 miles away, and projects are managed by a named contracts manager from first survey to handover.
The buildings we work on in Southampton are mostly NHS community hospitals and healthcare buildings. They are occupied buildings, so the works are planned in detail before we start on site: shutdowns agreed in advance, heavy work programmed into holidays or quiet periods, and temporary plant where heating or hot water has to stay on.
