If you run a business anywhere in Dorset right now, you’ve almost certainly felt it. Electricity sitting at 27–30p per kWh. Gas still expensive. Standing charges quietly eating hundreds of pounds every single month.
And yet… we’re seeing more and more Dorset companies quietly cutting their energy bills by 40–60%, improving staff comfort, hitting net-zero targets years ahead of schedule, and in many cases getting very healthy payback periods.
How? Mostly through big, properly designed commercial installations of:
- Large solar PV systems
- Commercial-scale air source heat pumps
- Battery storage
- EV charging hubs
- Heat recovery ventilation
We’ve been very busy delivering these kinds of projects across the whole area.
Here are the types of big commercial jobs we’ve been doing most often in Weymouth, Poole, Bournemouth, Christchurch and wider Dorset over the last 12–18 months.
Large retail & trade counters – massive rooftop solar + batteries
Very common right now. 30–80 kW solar arrays on flat or low-pitch commercial roofs. Almost always with 20–60 kWh of battery storage.
Typical result → 50–70% reduction in daytime electricity costs → Very strong Smart Export Guarantee income → Payback usually between 4.5–7 years
Best locations so far: Poole retail parks, Ferndown / Wimborne trade counter estates, Christchurch industrial areas
Office buildings & business centres – full heat pump + cooling retrofit
Three very strong project types we keep repeating:
- 40–120 kW total air-to-water heat pump cascades (usually 4–10 outdoor units)
- Reversible systems – heating in winter, active cooling in summer
- Very often combined with new heat recovery ventilation (HRV/MVHR)
Biggest wins:
- 60–75% reduction in heating bills
- Much better staff comfort & productivity
- Huge improvement in ESG / carbon reporting
Most of these jobs are happening in Bournemouth town centre and the business parks around Wallisdown / Winton.
Logistics, warehouses & fleet operators – solar + large EV charging infrastructure
This category exploded in 2025 and it’s still growing very fast.
Typical package right now:
- 30–100 kW solar (roof or solar canopy/carport)
- 10–40 EV charging points (mostly 22 kW AC, sometimes DC fast)
- Smart load management + battery buffer
Average outcome we’re seeing → £25,000–£60,000 annual saving compared to diesel → Very fast ROI when OZEV-style commercial grants are used → Weymouth harbour area + Poole port / logistics companies are leading this wave
Schools, care homes, community buildings – heat pumps + solar + ventilation
Working more and more with Dorset Council frameworks and Low Carbon Dorset funded projects.
Very common combination:
- 20–60 kW total heat pump capacity
- 15–40 kW solar PV
- Full fresh air heat recovery ventilation upgrade
Results that keep appearing:
- Energy bills cut in half (sometimes more)
- Much healthier indoor environment
- Noticeably happier staff / residents / children
Strongest clusters: Christchurch, Weymouth, Dorchester and the Purbeck area.
Quick Summary – What Almost Every Big Commercial Project Has in Common Right Now
- 40–65% typical energy cost reduction
- Payback usually 4–8 years (often faster with grants + SEG)
- Zero-rated VAT still in place (huge help)
- Very strong long-term protection against future price rises
- Big improvement in carbon reporting / ESG score
- Noticeably better working environment
