Mechanical Ventilation Heat Recovery is efficient ventilation for the home where the extracted air is used to heat the incoming ventilation air, using heat exchange.


Solar PV

Solar PV generates electricity from the sun to use in the home, this energy can also be stored in a battery or sold back to your energy supplier. Solar Thermal uses heat energy from the sun to heat your hot water or heat your swimming pool.



Heat pumps can also be used to cool a property in summer using MVHR, fan assisted radiators, or UFH.


Ground Source

Heat is extracted from the ground to be used to heat your home, hot water, and swimming pool. It can also be used in the summer to cool your home. A heat pump uses refrigeration to concentrate low level heat energy into usable heat.


Swimming Pools



Prevent heat loss from the roof of your home by installing additional insulation. We can add additional insulation when installing a heat pump to increase the efficiency of your home.


Underfloor Heating

Underfloor heating (UFH) uses pipes buried in the floor to heat or cool a room. This works well with a heat pump due to the low temperature required.


Battery Storage

Saving that production from your Solar PV and time shifting the free energy from daytime to nighttime.


Electric Vehicle

EV Chargers are often utilised with Solar PV to capitalise on the free solar energy from your system.


Rain Water Harvesting

Reducing water bills, lessening the strain on municipal resources and mitigating flood risk make them a worthwhile investment.


Air Source

Heat is extracted from the air to be used to heat your home and provide hot water. It can also be used in the summer to cool your home. A heat pump uses refrigeration to concentrate low level heat energy into usable heat.

All the professional staff at Wiltshire Energy (and the electricians!) are great and we send our thanks to each and every one of them. It was particularly nice to deal with you by: keeping us updated, sorting out any issues we had, providing “transparency” with your pricing and generally just being a nice guy to deal with. Oh, and thanks for sending the pictures – great idea!

Boiler bits cleaned, adjusted and certified. Also arrived when promised – having been let down by so many. Thoroughly recommend them.

Installed a heat pump under the GHG, so glad that I found someone local to do the work.

This was to install a heat pump meter, rapid response to enquiry, very reasonable quote, arrived on time, did the work neatly and efficiently. Very friendly and reassuringly competent. Highly recommended.

The team were very professional, they informed me how the installation would be carried out and worked around my schedule. I’m very happy with the results and have noted a vast improvement in my electricity bill. Better still; I don’t have a gas meter anymore!

Solar energy is an inexhaustible and free source

Solar energy is a simple and environmentally friendly way to produce electricity for yourself locally.

Combined with a battery, you can time shift production to when you actually need the energy.
