How it works

  • Register your installations

    We assess potential eligibility, identify missing information and structure qualifying activity for the applicable carbon programme.

  • Independent assurance and issuance

Questions * Answers *

  • Carbon credits represent measurable reductions in greenhouse gas emissions. When you install energy-efficient or low-carbon technologies (such as solar panels, heat pumps, or insulation), you effectively lower CO₂ output. These reductions can be converted into “credits” that have monetary value.

  • We welcome all project sizes - from individual homes to large portfolios. The more measures you install, the greater your carbon credits earnings.

  • Simply complete our data onboarding form with basic details about your installations. We’ll guide you through the submission process, verify your projects for carbon savings, and manage any auditing or compliance steps.

  • Government regulations and carbon market prices can fluctuate. We continuously monitor policy changes to minimise risks and keep you informed about adjustments that may affect your revenue.

  • Any organisation or individual installing energy-saving measures may be eligible, including:

    • Installers and contractors (monetise new and past projects)

    • Property owners, landlords, and housing associations

    • Developers looking for additional revenue streams

  • Yes, in many cases you can. Depending on the specific rules for the current or upcoming crediting cycles, installations completed within certain date ranges may still qualify. Contact us to find out if your past projects are eligible.

  • Once your carbon credits are verified and sold, you receive payments annually (or as defined by the relevant cycle). The exact amount depends on factors like the quantity of CO₂ reduced and the market price of carbon credits.

  • We handle most of the administrative work. All you need to do is provide project data (e.g., install dates, system details, certifications). Our team takes care of carbon calculations, verifications, and submissions on your behalf.

  • Yes. Credits are verified against recognised standards by independent third-party auditors. We prioritise high-integrity methodologies commonly accepted by housing associations and public-sector entities.

  • Feel free to book a quick consultation with our carbon credits specialists. We can provide a detailed assessment of your projects’ eligibility, estimated earnings, and next steps for submitting data.
