The Carbon Stamp is a UK-based carbon consultancy that helps small and medium-sized enterprises (SMEs) measure, reduce, and offset their carbon emissions. Founded in 2023 by Frazer Holroyd, we work directly with business owners and operations teams to produce accurate, GHG Protocol-aligned carbon footprint reports.
We specialise in helping businesses that need carbon credentials for UK government contracts (PPN 06/21), NHS supply chain requirements, SECR regulatory reporting, and client-driven sustainability requests. Our approach is hands-on — we guide clients through the entire process from data collection to final report delivery, rather than handing over a template and walking away.
We are registered at 128 City Road, London, EC1V 2NX and serve clients throughout the United Kingdom.
We measure your organisation's Scope 1, 2, and 3 greenhouse gas emissions following the GHG Protocol Corporate Standard. The process starts with a scoping call to understand your operations, followed by structured data collection covering energy consumption, business travel, employee commuting, purchased goods and services, and waste. We calculate emissions using government conversion factors (DEFRA/BEIS) and deliver a detailed carbon footprint report with a breakdown by emission source and scope. Typical turnaround is 4–8 weeks depending on data readiness. Learn more
PPN 06/21 requires suppliers bidding for UK government contracts over £5 million to publish a Carbon Reduction Plan on their website. We create fully compliant plans that include your current emissions baseline (Scope 1, 2, and 3), a commitment to achieving net zero by 2050, and specific, measurable reduction measures tailored to your business. The plan follows the Crown Commercial Service template and is ready to publish and submit with tender applications. This requirement is increasingly adopted by local authorities and NHS trusts beyond central government. Learn more
For emissions that cannot yet be eliminated through operational changes, we help organisations invest in verified carbon offset projects. We source offsets from established registries and help you understand the difference between avoidance and removal credits. Offsetting is typically used alongside a reduction strategy — not as a substitute for it. Learn more
We support organisations seeking to demonstrate carbon neutrality through a structured process: measure your full carbon footprint, implement reduction measures, offset remaining emissions, and obtain independent verification. This is relevant for businesses wanting to make credible carbon neutral claims to clients, in tenders, or in marketing materials. Learn more
Streamlined Energy and Carbon Reporting (SECR) is a UK regulatory requirement for qualifying large companies. If your organisation meets two of three criteria — over 250 employees, over £36 million turnover, or over £18 million balance sheet total — you must disclose energy use and carbon emissions in your annual directors' report. We prepare SECR-compliant data covering Scope 1 and 2 emissions, total energy consumption in kWh, and intensity metrics.
We work primarily with UK SMEs across healthcare, manufacturing, construction, professional services, hospitality, and food & beverage. Many of our clients come to us because they need a Carbon Reduction Plan to bid for government or NHS contracts, or because a major client has asked them to report their carbon footprint as part of supply chain sustainability requirements.
Notable clients include:
Most carbon consultancies are built for large corporations with dedicated sustainability teams. The Carbon Stamp is built specifically for SMEs — businesses with 10 to 250 employees that need practical, affordable carbon reporting without the complexity of enterprise-level consultancies.
The Carbon Stamp is a UK carbon consultancy specialising in helping SMEs measure, reduce, and offset their carbon emissions. We provide GHG Protocol-aligned carbon footprint assessments, PPN 06/21 compliant reduction plans for government tenders, and verified carbon offsetting services. We were founded in 2023 and are based in London, serving businesses across the UK.
Scope 1 emissions are direct emissions from sources a company owns or controls — company vehicles, on-site gas boilers, and manufacturing processes. Scope 2 emissions are indirect emissions from purchased electricity, heat, or steam. Scope 3 emissions cover all other indirect emissions across a company's value chain, including business travel, employee commuting, purchased goods and services, and waste disposal. For most SMEs, Scope 3 typically represents the largest share of total emissions. The Carbon Stamp measures all three scopes using GHG Protocol methodology and DEFRA/BEIS conversion factors.
PPN 06/21 (Procurement Policy Note 06/21) is a UK government policy requiring suppliers bidding for central government contracts over £5 million to provide a Carbon Reduction Plan. The plan must include your current Scope 1, 2, and 3 emissions, a commitment to net zero by 2050, and specific reduction measures. It must be published on your company website. This requirement is increasingly adopted by local authorities and NHS trusts beyond central government. Even if your contracts are below the £5 million threshold, having a Carbon Reduction Plan demonstrates environmental responsibility and can strengthen your tender submissions.
A typical carbon footprint assessment for an SME takes 4 to 8 weeks from start to finish. The process involves an initial scoping call, structured data collection (energy bills, travel records, procurement data, waste figures), emissions calculation using GHG Protocol methodology, and delivery of a detailed carbon footprint report. The timeline depends on data availability — businesses with well-organised energy and procurement records can complete the process faster.
Pricing is tailored to business size and complexity. Carbon footprint assessments typically start from £1,500 for SMEs. PPN 06/21 Carbon Reduction Plans are priced based on organisational scope and the number of sites involved. We provide a clear quote after an initial scoping call so there are no surprises.

SECR (Streamlined Energy and Carbon Reporting) is a UK regulatory requirement for qualifying large companies to report their energy use and carbon emissions in their annual directors' report. It applies to quoted companies, large unquoted companies, and large LLPs that meet two of three criteria: over 250 employees, over £36 million turnover, or over £18 million balance sheet total. Companies must report Scope 1 and 2 emissions, total energy consumption in kWh, and at least one intensity metric. The Carbon Stamp helps businesses compile and report this data accurately.
We work with UK SMEs across healthcare (NHS suppliers), manufacturing, construction, professional services, hospitality, and food & beverage. Many of our clients are businesses with 10 to 250 employees that need carbon credentials for government tenders (PPN 06/21), NHS supply chain requirements, or because a major client has requested carbon reporting as part of their own Scope 3 measurement.
All carbon footprint assessments follow the GHG Protocol Corporate Standard, which is the most widely used international framework for measuring and reporting greenhouse gas emissions. We use DEFRA/BEIS emission conversion factors (updated annually by the UK government) to calculate emissions from energy consumption, travel, procurement, and waste data. This methodology is recognised by government, industry bodies, and certification schemes.
