Commercial Heating, Ventilation and Air Conditioning Contractors in Ealing
Boiler house refurbishment, heating, ventilation, air conditioning and maintenance for acute hospital departments, diagnostic centres and schools in Ealing.
Preou in Ealing
Our largest single project is in Ealing: the £4.6 million mechanical and BMS installation for the new Community Diagnostic Centre at Ealing Hospital.
Ealing Hospital is on Uxbridge Road in Southall. Our engineers travel from Billericay, about 34 miles away, and projects are managed by a named contracts manager from first survey to handover.
The buildings we work on in Ealing are mostly acute hospital departments, diagnostic centres and schools. 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.
