Heat pump on house

Heat pumps are an energy-efficient way to heat your home while reducing your overall energy costs. Say goodbye to carbon-intensive fossil fuel dependence and hello to year-round comfort with a brand new heat pump.


Air source heat pumps extract heat from outside air to warm homes, offering energy efficiency and sustainability. With a reduced carbon footprint compared to traditional fossil fuel systems, they provide heating and hot water powered by electricity. All the models we offer are quiet and reliable, making them the choice for cost-effective, low-carbon heating. We have premium units from Stiebel Eltron and Viessmann as well as mid range heat pumps from Vaillant and Mitsubishi.

Stay Cosy and Save Energy. Switch to a Heat Pump.

Solar panels on roof with sun

Homeowners are installing solar panels to harness the power of the sun and slash energy bills. This sustainable energy solution is available all year round and helps for a cleaner, brighter future.
Solar panels work by converting sunlight into electricity. They generate electricity from ambient light, so even when the sun isn’t shining brightly, they can still produce power.


Excess energy generated can be stored in batteries or sold back to the grid. Overall, solar panels are a reliable and sustainable energy solution that can work in a variety of weather conditions in the UK.

Nice house with solar panels

Homeowners are adding battery storage to further increase energy self consumption and become energy independence. The power from the sun, or from the grid can be stored to use a later time when energy prices are higher. 

Batteries work by harvesting electricity in cells. They can be setup to store electricity from a solar system, or from the energy grid.

Overall, batteries are a reliable and sustainable energy solution. We have options from Tesla Powerwall, SolarEdge, GivEnergy and more.

Be Energy Independent. Store with a Battery.

"Polite, efficient, clean and friendly fitters, who know exactly what they are doing A++

The system is excellent, and was fitted without any problems at all.

I managed to talk our next door neighbours into having them fitted at the same time, so we both got an extra discount!"

The writing's on the wall. Gas boilers are being banned in new build homes from 2025.

The UK is on a determined path to reduce emissions, striving for net-zero by 2050.

In line with this commitment, new build homes will not be allowed to install gas boilers from now feature alternative, eco-friendly heating solutions, as traditional gas boilers, and the sale of gas boilers will be banned from 2035.

Industry-Leading Solar Technology

We use the latest in solar PV technology to provide you with the most efficient, reliable, and durable systems on the market. Our installations are designed to meet your energy needs now and in the future, ensuring your business reaps the benefits of clean energy for years to come.

Have any questions?

  • The key benefits include reduced energy bills, decreased carbon footprint, increased property value, and improved energy independence. Our solutions not only lower your reliance on traditional energy sources but also offer a cleaner, more sustainable way of living.

  • The short answer is no. ASHP's are actually very quiet. They do make some level of noise due to their working components, but all our installations are MCS Certified which means your heat pump is guaranteed to have a decibel noise rating of 45 or less at a 1-metre distance. That's less noise than the average home fridge makes and a little more than leaves rustling.

  • Yes, heat pumps are able to extract heat from the air even when temperatures are as low as -10, so you will still have a nice toasty house and hot water in even the coldest depths of winter.

  • All Air Source Heat Pumps can be installed to integrate with your existing radiators and are a great match for underfloor heating systems. Floors obviously cover a much bigger area than radiators so they don’t need to get as hot but will provide the same amount of heat. You can also combine your heat pump with solar photovoltaic (PV) panels which would make your carbon footprint even smaller!

  • The heat pump itself will be installed outside your house, ideally on the side or rear to minimise the external appearance of your property. It will need to be on a solid, flat surface such as a concrete base so it is stable and also be subject to good airflow to ensure maximum efficiency. It must also be situated a minimum of 1-metre away from any boundary lines to neighbours.

  • Providing you don't have a wind turbine on your property then you will not require planning permission as in most cases, the installation of an Air Source Heat Pump is classed as permitted development. Do always check with your local authority to err on the side of caution.
