Retail & Commercial
AHU works planned around
your trading hours.
Retail and commercial buildings operate on commercial timelines, trading hours, lease obligations, and EPC targets. AHU works have to fit around all of them. We plan around your calendar, not ours.

The operational constraint
Retail Can't Close
for Plant Works.
Retail properties trade six or seven days a week. A supermarket or shopping centre closing for AHU maintenance is not an option. Works have to happen around trading hours, and in most cases, around tenant lease obligations that limit what landlords can do and when.
- Night works with full reinstatement before trading opens
- Bank holiday and low-footfall window programming
- Access through trading areas agreed in advance and managed carefully
- Noise and dust contained, no impact on trading environment
- Plant room works during trading hours where containment is confirmed
- Co-ordination with estate management for access and permits
The energy pressure
Rising Energy Costs
and EPC Pressure.
Commercial property operators face growing pressure on energy performance. EPC ratings affect asset value and lease terms. AHU plant, particularly ageing belt-driven fan sets, is typically one of the largest energy consumers in the building. Targeted upgrades to EC fans and demand-controlled ventilation deliver measurable reduction at predictable cost.
EC fan upgrades
Replacing belt-driven fans with EC direct-drive within existing casings. 30–50% fan energy reduction, significant in buildings where AHUs run continuously during trading hours.
Controls and DCV
Demand-controlled ventilation reduces AHU energy consumption outside peak occupancy, particularly valuable in retail units with variable footfall throughout the day.
Energy performance documentation
We provide energy modelling and before-and-after performance data to support your energy reduction programme.

Common questions
Frequently Asked Questions
In most cases, yes. Works in contained plant rooms with no noise or dust impact on trading areas can proceed during opening hours. Works requiring access through trading areas, or that generate noise or dust, are scheduled for overnight or after closing.
Yes. We manage multi-site programmes across retail estates, with consistent scope, documentation, and delivery approach from one site to the next. This is common for facilities managers and retail property teams managing a number of assets.
Retail AHUs often run continuously to maintain a comfortable shopping environment. Replacing belt-driven AC fans with EC technology typically reduces fan energy consumption by 30–50%, a measurable reduction in operating cost and a direct contribution toward EPC rating improvements.
We focus on AHU and ventilation works. We do not carry out refrigeration maintenance or repair. However, we work alongside refrigeration contractors on integrated HVAC refurbishment projects where both scopes are running concurrently.
Yes. EC fan upgrades, controls upgrades with demand-controlled ventilation, and heat recovery modifications all deliver measurable energy reduction and contribute to EPC rating improvements. We provide energy modelling and before-and-after performance data to support these programmes.
This varies by landlord and tenant arrangement. We discuss access requirements at survey stage and build them into the programme. For retail parks and shopping centres with managed access, we co-ordinate directly with the estate management team.
