Reduce your carbon footprint and energy bills with A Ground Source System

We launched our renewable division in 2000, ever since then we have installed ground source systems for homes and offices. We won a Worcester Bosch Environment 2020 award  for our installation of ground source heat pumps, mainly using the NIBE and Worcester brands. With renewable technologies, you can help the environment and save money, you can even get money back from the government – so it’s win-win!

When it comes to ground source systems, the key is in the name! They source heat from the ground using a network of pipes and pumps that are buried underneath your garden.

Providing heat and hot water all year round, they are a long-lasting, sustainable investment. In fact, you can save up to 80% on your heating bills with a ground source system harvesting free energy from the earth.

Ground Source Heat Pumps capture energy from the earth, saving the planet whilst you save money!


Ground source heat pumps use the energy stored in the ground to heat your home and hot water all year round. A pipe loop is installed underneath your garden and can be controlled from a unit inside your house, making it easy and efficient to manage.

This streamlined system will save you money on heating bills, fuel bills and even creates a more efficient heat distribution system, saving you up to 80% on your annual fee.


A ground source heat pump comprises of a loop of pipe that is installed underneath your garden which is connected to a control unit inside your home.

The pipe is filled with a mixture of anti-freeze and water. As this solution moves through the pipes, it absorbs the heat from the ground. This heated solution is then passed through a compressor, increasing the pressure and temperature of the fluid. This then produces the hot water that is fed into your system, providing you heating and hot water! Once it’s been used, the fluid flows back into the ground loop to re-heat.


Ground Source Heat Pump


The benefits of ground source heat pumps include:

  • Lower heating bills
  • Reduced carbon footprint
  • Heating for both your home and your hot water
  • No fuel bills
  • Heat delivered over a longer period of time compared to gas or oil boilers
  • Potential income through the government RHI scheme
  • No outside units so aesthetically better


Most ground source heat pumps are eligible for the UK government’s Renewable Heat Incentive (RHI) scheme. This scheme – which began in 2014 – entitles those who have certain renewable systems to seven years of quarterly cash payments for their investment in sustainable practices. You can also pay a reduced VAT rate on these products. Through RHI, many Lewington Heating customers receive income for their investment in renewables! Find out if you are eligible for RHI scheme, and contact us about a cost effective GSHP installation today.


The UK Government offers a variety of grants and financial incentives to encourage UK homes to swap to renewable heating systems.

    Customer FAQs

    Yes, all heat pumps will require a hot water cylinder and suitable space around to conceal all the equipment.

    Yes, heat pumps are perfect for underfloor heating as it works hand in hand with the heat pump temperature of 40 – 45 degrees.

    A heat pump will typically deliver a flow temperature of 40 – 45 degrees so your existing rooms will need to be able to cope with the lower radiator surface temperature. If not you may be advised to increase the size of the radiator or look at alternative fan assisted radiators.

    A typical system requires about 700 square meters of land to lay out the pipe loops.

    First and foremost you need to have a well-insulated house, due to the low running temperatures of an heat pump you need to be able to retain the heat in the property. Also you must have room inside to conceal the equipment. The Heat pump itself and the hot water cylinder are typically the size of large fridge freezers. A garage or plant room is ideal.

    There is currently the RHI scheme which is due to finish at the end of March 2022. This is being replaced with a one off payment of £5000 from the government towards replacing your existing boiler for a heat pump.
