Solar PV & Battery Storage

Ely, Cambridgeshire

4.5kW Solar + 5kWh Battery in Ely

A Victorian semi-detached property in Ely with a south-facing rear roof, ideal for solar generation. The homeowners wanted to reduce their electricity bills and maximise self-consumption with battery storage.

System Details

12 x 375W black-framed monocrystalline panels
4.5kW total system capacity
5kWh lithium iron phosphate battery
Hybrid inverter with app monitoring
Smart Export Guarantee registered

Cost Range

8,500 - 10,000

Annual Saving

1,100/yr

Estimated 70% reduction in electricity bills with battery self-consumption, plus SEG export income of approximately 120 per year.

"We were nervous about solar on a period property, but the team were brilliant. The black panels look great on the slate roof and we are saving over 90 pounds a month. Wish we had done it sooner."

- Mr and Mrs Davies, Ely

Commercial Solar PV

Bury St Edmunds, Suffolk

12kW Commercial Solar on Warehouse in Bury St Edmunds

A distribution warehouse in Bury St Edmunds with a large flat roof area and high daytime electricity usage. The business owner wanted to cut operating costs and reduce the company carbon footprint.

System Details

30 x 400W commercial-grade panels
12kW total system capacity
Three-phase string inverter
Commercial monitoring and reporting system
Flat roof ballasted mounting system

Cost Range

14,000 - 17,000

Annual Saving

4,200/yr

Projected payback period of 3.5 years with near-100% self-consumption during business hours. 0% VAT applied as energy-saving material.

"The payback is incredible. Our electricity bill has dropped by around 350 pounds a month and we have been able to promote our green credentials to clients. The installation was completed in just two days with no disruption to operations."

- James, Operations Director, Bury St Edmunds

Air Source Heat Pump

Swaffham, Norfolk

Air Source Heat Pump Replacing Oil Boiler in Rural Norfolk

A detached farmhouse near Swaffham running on an ageing oil boiler with annual heating costs exceeding 3,000 pounds. The owners qualified for the Boiler Upgrade Scheme (BUS) grant of 7,500 pounds, making the switch to an air source heat pump highly affordable.

System Details

12kW air source heat pump
New radiator upgrades to selected rooms for low-temperature efficiency
210-litre hot water cylinder
Smart thermostat with zoned heating controls
BUS grant of 7,500 applied

Cost Range

12,000 - 15,000 (before BUS grant)

Annual Saving

1,400/yr

Annual heating costs reduced from over 3,000 pounds (oil) to approximately 1,600 pounds (heat pump electricity), a saving of 1,400 pounds per year. Net installation cost after BUS grant from 4,500 pounds.

"We had been dreading the cost of replacing our oil boiler. The BUS grant made the heat pump affordable and the house has never been more comfortable. No more oil deliveries, no more fluctuating fuel prices, and the running costs are genuinely lower."

- The Richardson Family, Swaffham

Agricultural Solar PV

Newmarket, Suffolk

50kW Agricultural Solar on Grain Store near Newmarket

A working farm near Newmarket with a large south-facing grain store roof. The farm had significant electricity usage for grain drying, cold storage, and general operations, making it an ideal candidate for a large-scale agricultural solar installation.

System Details

120 x 420W high-efficiency panels
50kW total system capacity
Three-phase commercial inverter system
Roof-integrated mounting on corrugated steel
Remote monitoring and yield tracking

Cost Range

42,000 - 50,000

Annual Saving

11,500/yr

Generating approximately 47,000 kWh per year, covering the majority of the farm electricity demand. Projected payback period of 4 years with SEG export income on surplus generation.

"The grain store roof was doing nothing except keeping the rain out. Now it is generating most of our electricity. The team understood agricultural buildings and the install was done between harvests without any issues. It is the best investment we have made on the farm."

- Robert, Farm Manager, near Newmarket

Solar PV, Battery & EV Charging

Cambridge, Cambridgeshire

Solar + Battery + EV Charger Complete Package in Cambridge

A modern detached property in Cambridge where the homeowners wanted a complete energy package: solar generation, battery storage for evening use, and an EV charger to power their new electric car from the sun.

System Details

16 x 400W all-black panels (6.4kW system)
9.5kWh battery storage system
7kW smart EV charger with solar diversion mode
Energy management system linking all three components
App-based monitoring for solar, battery, home usage, and EV charging

Cost Range

14,500 - 17,500

Annual Saving

2,200/yr

Combined annual savings of approximately 2,200 pounds across electricity bills and avoided petrol costs. The EV charges almost entirely from solar during summer months, and the battery covers most evening usage year-round.

"Having everything integrated by one installer made a huge difference. The app shows exactly where our energy is going and we charge the car for free most of the summer. Our total energy costs including the car are less than half what we used to pay for electricity and petrol."

- Dr and Dr Okonkwo, Cambridge

Insulation & MVHR

Thetford, Norfolk

External Wall Insulation + MVHR on 1960s Property in Thetford

A 1960s semi-detached property in Thetford with solid walls, poor insulation, and persistent condensation issues. The owners wanted a fabric-first approach to reduce heating costs and improve indoor air quality before considering renewable heating.

System Details

100mm external wall insulation with silicone render finish
Full mechanical ventilation with heat recovery (MVHR) system
Loft insulation top-up to 300mm
Draught-proofing throughout
New EPC rating improved from E to C

Cost Range

18,000 - 22,000

Annual Saving

950/yr

Heating demand reduced by approximately 45%. The MVHR system eliminated condensation and mould issues while providing constant fresh filtered air. The improved EPC rating also increased the property value.

"The house used to be freezing in winter and we had mould in the bedrooms. Since the insulation and MVHR went in, it is like living in a different house. The air is fresh, the walls are warm to the touch, and our gas bill has nearly halved. We only wish the outside had always looked this good."

- Sandra and Keith, Thetford
