Qila Energy is a leading British engineering company, funding and building biomethane plants across the UK.

Qila Energy is a British engineering company that has established itself as a market leader in funding, designing, building and operating Biomethane Gas to Grid and CHP biogas plants/ anaerobic digestion (AD) plants throughout the UK.

  • Qila has raised over £200 million from investors to provide farmers with full funding as project finance.
  • Qila has under contract 27 biogas plants ranging from large Biomethane Gas to Grid and Virtual Pipeline, to 499kWe CHP.
  • Qila’s hydrolysis/ turbo tank design is proven technology.
  • Qila has operational plants running on average above their performance guarantee of 92% full load hours p.a.
  • Qila has designed and installed a bespoke control system to enable remote access to all our biogas and biomethane plants.
  • Qila’s Operations and Maintenance team provide all the plants with remote monitoring and servicing 24/7, 365 days a year.
  • Qila continues to raise funding and develop new RHI projects incorporating at least 50% waste (foodwaste, straw, manures).

Qila Energy - Top of the Leader-board

Ruby Jones

CEO, Co-Founder

Qila Energy’s leadership stands out from its competitors in several ways:

  • Qila provides all services under one roof; planning, design, construction, engineering, operation and maintenance.
  • Qila arranges full funding for the biogas plant to be built and operated.
  • Qila has a unique 2-stage design for the AD/ biogas process.

Qila demonstrates exceptional leadership throughout every stage.

Our Project Finance team raises the money needed for the plant, our Planning Team secures planning permission, our Design and Construction Teams design the biogas or biomethane plant, tenders civils, mechanical and electrical work streams and our Operation and Maintenance Teams provide our farmers/ operators with full operator training and ongoing engineering support.

Qila ensures that the land owner, farmer and local community is supported every step of the way. Once the plant has been constructed, we help with full training, weekly feedstock and biogas testing, along with 24/7 maintenance and support, all year round.

Qila has established itself as a UK market leader, and is committed to maintaining our excellent reputation with all our investors, landowners, operators, feedstock suppliers and farmers.

Why choose Qila Energy?

Unlike other AD/ biogas companies, Qila’s bespoke 2-stage design with a Hydrolysis/ Turbo Tank means our biomethane and biogas plants create a higher biogas yield, allowing for increased efficiency and the ability to digest larger proportions of cattle manure, chicken litter and grass silage compared to 1-stage plants.  We have also designed and manufactured our own control system, allowing us to monitor all our plants 24/7, 365 days a year and act quickly to any problems that may occur.


What is particularly special at Qila, is that we build on relationships with each individual farmer through every stage of the process. We do this by providing all the services needed under one roof:

  • Planning Permission
  • Project Finance
  • Project Management
  • Biogas & Biomethane Engineering Design
  • Construction, Healthy & Safety, CDM
  • Commissioning
  • Operation and Maintenance
  • Feedstock & Laboratory Support

Do you need funding for New RHI?

Get it right from the start and talk to us from the start, half of our farmers started with another developer who failed to deliver funding, or failed to build the plant properly - We all lose money and time when we have to change planning permissions, retro fit plants or arrange funding last minute, with substantial costs incurred by the farmers.

Virtual Pipeline


Portsdown is a Virtual Gas Injection Facility operated by SGN. This virtual pipeline is the first of its type in Europe and provides an alternative to on-site gas injection plants dependent upon getting a gas connection to a gas pipeline that has sufficient capacity on the same site as their biomethane plant.

Qila Energy has secured capacity at Portsdown  and we are actively working with farmers within 1 hours drive from Portsmouth to fund and build a biomethane plant that tankers the green gas to the SGN virtual pipeline facility.

If you have a site with good road access then please contact us and we will come and see you for a site assessment.  Some of our farmers want to just be the landlord and get paid site rental, some also want to supply feedstock and get an attractive long term feedstock contract.  If your site is suitable, then Qila has the funds and expertise to pay for planning permission, build the plant and operate the plant - you don't need to have any financial outlay.  Learn More →

Biomethane Director

Project Finance & Project Development

Our Project Finance and Development Team is lead by Paul Thompson, who joined Qila as Head of Biomethane from the Renewable Energy Association (REA) in August 2015 and has coordinated and secured numerous projects through meeting RHI deadlines and getting projects funded on time.

Despite the continually changing Renewable Heat Incentive (RHI), our Project Finance & Development team has contributed greatly to the development of biomethane in the UK by raising £88 million for the development and construction of 8 new biomethane plants.

Proven Biogas & Biomethane Technology

We design our biogas and biomethane plants in-house with our civil, mechanical, electrical and process engineers.  

Our Turbo Tank is heated to enable hydrolysis (where carbohydrates, lipids, nucleic acids and proteins are converted into glucose, glycerol, purines and pyridines) to occur faster. Methanogenesis is the last step in the biogas process and severely influenced by operational conditions such as:

  • Composition of feedstock
  • Feeding rate
  • Temperature
  • pH
  • Digester overloading, temperature changes or large entry of oxygen can result in termination of methane production

By trying to separate hydrolysis from methanogenesis our design eliminates problems with feeding, temperate and pH as all feedstocks are fed into the Hydrolysis/ Turbo Tank, heated and mixed in a relatively acidic pH environment before being pumped into the digester where methane bacteria are more efficient at a lower temperature and natural pH. We can produce 20-30% more biogas from a given tonne of feedstock compared to a single stage plant with just a digester, we can also take a much larger range of diffuclt feedstocks such as cattle manure, straw and chicken litter.
