Energy costs remain a pressure point for most commercial operators. Electricity pricing volatility and ongoing operating costs are forcing businesses to look at more efficient, long-term solutions.
Across Dorset, there is a clear shift toward properly designed systems that reduce energy consumption while improving internal conditions. Over the past 12–18 months, we’ve delivered a range of commercial projects focused on:
- Solar PV systems
- Air source heat pump systems
- Air conditioning (air-to-air) systems
- Battery storage
- EV charging infrastructure
- Heat recovery ventilation
Below is a breakdown of the types of projects we’re most frequently delivering across Weymouth, Poole, Bournemouth, Christchurch, and the wider Dorset area.
Retail & Trade Counters – Solar + Battery Installations
This remains one of the most common upgrades.
Typical setups include:
- 30–80 kW rooftop solar arrays
- 20–60 kWh battery storage
Observed outcomes:
- Significant reduction in daytime grid usage
- Export income via Smart Export Guarantee (SEG)
- Typical payback periods in the 4.5–7 year range (site dependent)
Common locations include retail parks and trade estates in Poole, Ferndown, Wimborne, and Christchurch.
Office Buildings – Heating & Cooling System Upgrades
We’re seeing consistent demand for full HVAC upgrades in office environments.
Typical configurations:
- Air source heat pump systems (correctly sized to building demand)
- Reversible operation (heating and cooling)
- Integration with heat recovery ventilation where required
Key benefits:
- Reduced heating and cooling costs
- Improved temperature control across seasons
- Better indoor air quality and staff comfort
Most of these projects are concentrated in Bournemouth and surrounding business parks.
Example Project: Primark Weymouth
The installation at Primark Weymouth is often referenced, so it’s important to describe it accurately.
This was not an air-to-water or cascade system.
The site uses:
- Air-to-air air conditioning / ASHP system
- Mitsubishi Electric heat recovery system
This type of system allows simultaneous heating and cooling across different zones, improving efficiency and control in a large retail environment.
Logistics & Industrial Sites – Solar + EV Infrastructure
This sector has expanded quickly.
Typical project scope:
- 30–100 kW solar installations (roof-mounted or canopy)
- 10–40 EV charge points (primarily 22 kW AC, with some DC fast charging)
- Load management systems and optional battery storage
Typical outcomes:
- Reduced fuel and energy costs (case dependent)
- Improved fleet electrification capability
- Better control over peak demand
Activity is particularly strong around Weymouth Harbour and Poole port/logistics areas.
Schools, Care Homes & Community Buildings
We continue to support projects in public and community sectors, often working alongside principal contractors and funded programmes.
Typical systems include:
- 20–60 kW heat pump capacity
- 15–40 kW solar PV
- Heat recovery ventilation systems
Results typically include:
- Lower overall energy consumption
- Improved indoor air quality
- More stable internal temperatures
Projects are commonly located in Christchurch, Weymouth, Dorchester, and Purbeck.
What These Projects Have in Common
Across most commercial installations, the consistent outcomes are:
- Measurable reductions in energy consumption
- Improved environmental control within buildings
- Increased resilience against energy price fluctuations
- Better alignment with carbon reduction targets
Payback periods and savings vary depending on system design, usage patterns, and available funding, so accurate site assessment is essential.
Considering an Upgrade?
If you operate a medium to large commercial building in Dorset and your energy costs are significant, a properly specified system can materially improve both operating costs and internal conditions.
A typical starting point includes:
- Review of the last 12 months of energy usage
- Assessment of available roof or plant space
- Evaluation of current heating and cooling systems
- Outline of realistic system options and financial projections
