IEC Heat Solutions is part of a family-owned farming business, Wilson Farming, with more than 40 years’ experience working with the agriculture sector

Wilson Farming created IEC Heat Solutions, as part of International Energy Crops Ltd (IEC) in 2010, after installing their own on-farm renewable heating and recognising the benefits that similar projects could have for a range of agricultural and commercial businesses.

IEC Heat Solutions are now leading designers, suppliers and installers of bespoke biomass and ground source heating systems to agricultural and commercial businesses across England and Wales.

Our in-house design capability means that every project is tailor-made to meet the specific neds of an individual farm or company, whatever its size. IEC have the experience and industry knowledge to identify the best heating solutions for each customer.

IEC has a large customer base within the poultry sector, providing renewable heating for various drying facilities, as well as delivering installations for glasshouses and other farm structures and public buildings. We are renowned for our unbeatable aftercare, and our experienced engineers are always on hand to ensure that your system is running to maximum efficiency and reliability.


Since 2010, we have designed and installed over 250 biomass systems across England and Wales, specialising in medium and large 500kW- 10mW biomass heating installations.

With industry changes in fuel supply and prices, planning and permit restrictions and more diverse business models for many customers, IEC can commission bespoke Ground Source Heat Pump (GSHP) projects. We specialise in innovative engineering designs which work with existing site operations to provide a bespoke system with an efficiency which cannot be matched by more standard installations.
