Biomass CHP units generate electricity and heat from sustainably sourced wood fuel, such as pellets or wood chips.

A gasifier converts the biomass into a combustible gas, which is then used to power an engine or turbine. This generates electricity for on-site use or export, while the heat produced in the process is captured and reused for heating buildings, manufacturing processes, drying agricultural produce, or supplying hot water.

This dual-output system significantly increases overall efficiency compared to standalone boilers or generators – offering energy security, low-carbon output, and financial return in a single integrated solution.

How do they work?

Combined Heat & Power - How do they work?

  • Combined Heat & Power from Biomass
    Simultaneously produce renewable electricity and useful heat from sustainable fuel.
  • Support Net Zero & ESG Goals
    Cut carbon emissions dramatically and meet regulatory and investor-led climate targets.
  • Offset Energy Costs
    Reduce your reliance on volatile grid prices and secure your own renewable supply.
  • Eligible for Incentive Schemes
    Access legacy support (RHI) or future schemes supporting renewable heat and energy resilience.
  • Ideal for Energy-Intensive Sites
    Perfect for farms, food producers, leisure facilities, off-grid businesses, and rural estates.
  • Long-Term ROI
    Smart energy savings and potential export revenue over 15–25 years of reliable operation.

Solutions proven to work

We used ESP from recommendation following a couple of failed attempts to get others to quote, one call to Ross at ESP and the ball was rolling. Ross attended site on multiple occasions to asses the site, and offer comprehensive guidance on the best system to use on our site. His staff are all more friendly and helpful, there was a wait on commissioning of the system, and whilst a little frustrating as we were excited to get up and running the time was useful as it allowed us to sort out what we were going to do with our electric meter, is the one we had is unable to measure units to export. ESP also offer A lot of help and advise on sorting this to, we look forward to the saving on return of investment, and would not think twice to use ESP again for any similar projects.

The team were fantastic, From quoting through to order, install & commissioning, they were super responsive, incredibly competent, and nothing was too much trouble.

They put up 22 solar panels, a Tesla Powerwall 3 battery, connected two energy supplies into 1, dug trenches between buildings, installed a Cat6 ethernet cabling system AND kept cost reasonable with no shocks. Above all, they were nice guys! I cannot recommend this company strongly enough.

Dez O'ConnorBiomass Boiler Owner

Superb local company who service our Austrian biomass boiler with expertise and resourcefulness. I’ve been happy to recommend to my friends who also have biomass boilers. I’m very grateful to the ESP team and their knowledge and responsiveness.

FAQS

Depending on your current setup, switching to biomass CHP can reduce CO₂ emissions by 60–90%, especially if replacing oil, LPG, or grid electricity.

Many systems installed under the RHI continue to receive support. Future schemes are expected as part of the UK’s Net Zero strategy and we can help you navigate them.

CHP systems require regular servicing, it also benefits from having a skilled engineer on site to undertake daily and weekly checks and tasks. As the UK’s CHP specialists, we offer comprehensive maintenance plans and stock critical spare parts.

Timelines vary by project size and complexity, but a typical installation ranges from 6–12 weeks including design, prep, and commissioning.

Yes, when fuel is sustainably sourced, biomass is considered a carbon-neutral energy source, as the CO₂ emitted is offset by the carbon absorbed during growth.
