Mr. Smith's home was losing a lot of heat through uninsulated cavity walls, leading to cold draughts in the living area and rising gas bills each winter.

Our team drilled small access holes and injected high-performance mineral wool into the wall cavities, reducing heat loss and creating a more comfortable, even temperature throughout the home, with estimated bill savings of around £200–£230 per year based on a typical gas-heated property. The work was completed in under a day with minimal disruption, and Mr. Smith is now benefitting from warmer rooms, fewer draughts and an improved EPC rating. Read more

Mrs. Jones noticed that the front bedrooms were always colder than the rest of the house, with condensation forming on the external walls during colder months.

After a suitability survey confirmed clear, accessible cavities, we installed modern blown-fibre insulation to the external walls, sealing gaps where heat was escaping, which is expected to cut annual heating costs by around £150–£200 and reduce carbon emissions for this property. The installation was arranged under a government-backed insulation scheme, reducing the upfront cost significantly while delivering long-term savings. Read more

Ms. Patel's property was expensive to heat, and the external walls felt noticeably cold to the touch, clear signs that the cavities were not insulated.

We carried out a full cavity fill using high-quality mineral wool insulation, targeting all accessible external walls to create a continuous thermal barrier around the home, delivering projected savings of around £200 per year on heating bills and cutting CO2 emissions over the lifetime of the insulation. The upgrade was part-funded through a government scheme, helping Ms. Patel benefit from warmer rooms, lower bills and a more energy-efficient home. Read more

A family in Birmingham struggled with high heating bills and cold bedrooms during winter months due to insufficient loft insulation in their 1980s semi-detached home.

We installed 270mm of premium glass wool insulation, upgrading from the original 50mm, which now saves the family approximately £350–£400 per year on heating costs, while significantly improving upstairs comfort and reducing their carbon footprint. The installation was completed through the ECO5 scheme with zero upfront cost to the homeowner. Read more

A retired couple in Leeds wanted to improve their home's energy efficiency and reduce heat loss through their poorly insulated loft space in their Victorian terraced property.

Our team installed 300mm of mineral wool insulation between and over the joists, ensuring full coverage and proper ventilation to prevent condensation, transforming their cold loft into an effective thermal barrier that maintains consistent indoor temperatures year-round. The upgrade qualified for government funding and is projected to cut annual heating bills by up to 25%. Read more

A homeowner in Bristol noticed drafts and excessive heat loss from their 1970s detached bungalow, where the original loft insulation had compressed and degraded over time.

We topped up the existing insulation to meet current building regulations with 270mm of high-performance insulation, carefully working around stored items and maintaining access routes, creating an energy-efficient home that stays warmer in winter and cooler in summer. The installation was funded through the Great British Insulation Scheme and is expected to save over £300 annually while increasing the property's EPC rating. Read more

A busy professional family in Essex wanted to cut rising electricity bills and make better use of their south-facing roof with a high-performance solar PV system and battery storage.

Smart monitoring lets the family track generation and shift high-consumption activities into sunny periods, turning an underused roof into a long-term asset that delivers clean, low-cost power while supporting Essex's move towards renewable energy. Read more

A family in Manchester wanted to reduce their dependence on grid electricity by adding a modern solar PV system with battery storage.

The install now generates over 5,000 kWh a year and is projected to save around £1,200–£1,500 annually on electricity bills, with the battery capturing daytime surplus so the family can run evening usage and high-demand appliances on stored solar instead of expensive peak-rate power. Read more

We are preparing our next solar PV and battery case study showcasing another customer who has transformed their home with renewable energy.

This upcoming project will highlight how solar and smart storage can further cut bills and carbon emissions, demonstrating how Simple Green Energy designs systems around each home's roof, usage patterns and budget to maximise long-term savings. Read more
