Energy Efficiency Solutions

Air Source Heat Pumps


ASHPs work by taking the heat from the outside air and transferring it to your indoor space via the heating system. It works just like a refrigerator, transferring air from one space to another. Some systems can also be used as a cooling solution in the summer months.

Ground Source Heat Pumps


GSHPs work in a similar way to ASHPs, however they take the heat from the ground. It uses pipes that are buried underground to collect heat and run it through the heating system up to the building above.

Underfloor heating


Underfloor heating works with most types of heating systems, but we think they work great with ASHPs and GSHPs. The heating system is embedded in the floor, meaning it’s more energy efficient, there’s less noise and no maintenance.

Biomass boilers

Biomass boilers work in the same way as traditional boilers; however, they burn on natural fuels instead. You can choose from logs, wood chips or wood pellets, making them an energy-efficient and cost-effective heating solution.

Solar thermal

Solar thermal systems work by collecting heat from solar panels attached the roof of a building. The heat is then passed into the heating system of the property and stored in the hot water cylinder. This natural heat source makes it a really energy-efficient heating solution.

Solar Photovoltaic (PV) & battery storage

Solar photovoltaic systems work in the same way that solar thermals do, but the heat is transferred into electricity rather than hot water. The electricity can then be used in the property, exported back to the grid or stored in a battery storage system.

Mechanical Ventilation Heat Recovery


MVHR is a great solution for housing ventilation. It gets rid of moisture and stale air and replaces it with fresh air. The fresh air gets pre-heated before pumped around the property. Most systems have air filtration built-in to prevent pollen and other particles entering the air.

Waste Water Heat Recovery


WWHR takes the waste water from when you use the shower, passes it through a heat exchanger and uses it to heat up the cold water powering your shower. Less energy is used to heat up the water, meaning it’s really energy-efficient.

Radiators & Infrared Heating


Infrared heating is an energy-efficient alternative to traditional radiators. Instead of using water content, they use infrared technology to heat the room. They are usually installed on walls or ceilings to allow maximum reach of heating.

Rain Water Harvesting


Rain water harvesting is the process of collecting and storing rain. The rainwater runs off of your rooftop, into the guttering and is redirected into a tank. It is then stored for later use for things such as car washing, or internal uses like washing and toilet flushes.

Hydrogen Boilers


Hydrogen boilers are a low-carbon alternative to natural gas boilers. As our supply of natural gases becomes less and less, we are always looking for low-carbon heating solutions. Hydrogen boilers work in the same way as existing gas boilers, but use pure hydrogen as fuel.

Electric Vehicle Charging


Electric vehicle charging points (or EV charging) are machines that supply electric to charge plug-in electric vehicles. This is better for the environment as the vehicles use less fuel. Each charging point has an adapter that connects to the vehicle, which then converts the power internally and charges the battery.

Underfloor Heating from Graham

Under flooring heating is an affordable, energy-efficient heating solution for properties of all sizes. Radiant heat works by heating up the room from systems that run under the floor, turning it into a radiator.

Future Homes Standard

The Future Homes Standard will require new build homes to be future-proofed with low carbon heating and world-leading levels of energy efficiency.

Domestic Renewable Heat Incentive

The Domestic Renewable Heat Incentive is a government financial incentive to promote the use of renewable heat. Switching to heating systems that use eligible energy sources can help reduce its carbon emissions.
