Green Efficiencies Limited offers a range range of Green Deal measures to improve energy efficiency of domestic and commercial properties.

Green Deal Survey

A Green Deal assessor will spend around two hours undertaking a thorough inspection of both the energy efficiency and the useage of energy in the property. The survey will help you to understand your property’s energy efficiency.  The survey will also assess how you and the people living at the property use energy, and based on these findings will recommend energy saving improvements tailored to your particular property.  The measures we offer are detailed below.

Cavity Wall Insulation

Most modern homes are constructed with an ‘air-gap’ or cavity walls, filling this gap with the appropriate insulating material can significantly reduce heat loss.  The insulation technician will start the process by drilling a series of small holes into the outside wall of your property.  The insulating material is then pumped into the cavity using specialist equipment.  The insulating material can be made from a variety of different material, but it’s usually made from recycled granulated mineral wool fibre or polystyrene beads.  This creates a blanket effect that will prevent heat escaping.

Loft Insulation

A roll of environmentally friendly mineral fibre that is laid in your loft.  Loft insulation installers lay one layer in between the joists and another layer length ways across the joints.  This would then bring your property in line with Building Regulation standards and will last indefinitely, so you do not have to change it again.

Pitched Roof Insulation

Homes that have had a loft conversion built before 1995 or properties that are built as a chalet style house are unlikely to meet current Building Regulations and therefore the current level of insulation will not be sufficient to prevent heat escaping.  By having these areas insulated you could save up to 25% on fuel bills.

Internal Wall Insulation

This system is provided by building up thermal studwork with a glass mineral wool insulation.  Once fitted, walls are finished with plasterboard, leaving a fresh clean surface ready for redecoration. The process does not affect the outside walls and will have minimal impact on the household as it can be completed one room at a time.

External Wall Insulation

Homes built before 1920 are built with one solid wall, which means that they let out lots of heat, making your home very inefficient and costly to heat.  External wall insulation is fixed to the outside of the wall with a decorative render to finish.  This provides your outside wall extra protection, filling gaps and cracks and weather proofing the building.  It also offers improved sound resistance.
