What The Carbon Stamp does
The Carbon Stamp is a UK-based carbon consultancy founded in 2023 by Frazer Holroyd that delivers carbon footprint assessments, PPN 006 Carbon Reduction Plans, ISO 14068-aligned carbon neutral certification, SECR reporting, and net zero strategy services exclusively to UK SMEs (3–250 employees). The firm operates a consultant-led, professional-services model with no SaaS subscription layer, using a proprietary three-phase methodology (Identify, Collect, Deliver) built on activity-based data (kWh, litres, km, kg) and UK Government DESNZ conversion factors, explicitly refusing spend-based estimation. Pricing is fixed-fee by employee headcount band, ranging from £1,295+VAT for a 3–10 employee Carbon Impact Report up to £4,195+VAT for mid-market Procurement-Ready Packages, with offset credits priced separately at £6.50/tCO2e+VAT.
Revenue is generated through one-off project engagements initiated via a free 30-minute discovery call, with annual recalculation engagements available at discounted rates for returning clients. The go-to-market is sales-led and inbound-driven — content marketing (blog, YouTube, downloadable PPN 006 templates), SEO-optimised vertical pages, and free self-serve tools (Supplier Engagement Portal, Employee/Company Carbon Surveys) feed qualified discovery calls, with field sales (on-site scoping and board presentations) reserved for mid-market clients. The company is registered as The Carbon Stamp Ltd (company number 14720145) in England & Wales, headquartered at 128 City Road, London, operates primarily remotely across the UK, and is a member of the NHS Net Zero Expert Network with UK Government Approved Supplier status. No external funding rounds have been disclosed; the firm is bootstrapped and founder-owned.

The Carbon Stamp partnerships and signals
Strategic signalPartnerships
Nine partnerships are on record, tiered core and minor.
- NHS Net Zero Supplier RoadmapcoreThe Carbon Stamp's services are aligned to the NHS Net Zero Supplier Roadmap requirements, which mandate Carbon Reduction Plans for all NHS suppliers. Since April 2024, the NHS requires CRPs for all new procurements (not just contracts over £5 million). The NHS targets Net Zero by 2040 for direct emissions and 2045 for the supply chain (Carbon Footprint Plus), requiring 80% supplier emission reduction by 2028–2032. The Carbon Stamp has multiple NHS supplier clients (Medicom Healthcare, Eco Ninjas, Eitan Medical) who use the service to maintain NHS procurement eligibility.
- PPN 006 / PPN 06/21 Compliance FrameworkcoreThe Carbon Stamp's core service is aligned to UK Government Procurement Policy Note 006 (formerly PPN 06/21), which requires suppliers bidding for government contracts over £5 million to submit a compliant Carbon Reduction Plan. The company's Procurement-Ready Package delivers signed, GHG Protocol-aligned PPN 006 CRPs covering Scope 1, 2 & material Scope 3. Multiple case studies demonstrate successful tender outcomes for clients using The Carbon Stamp's PPN 006 service.
- GHG ProtocolcoreAll The Carbon Stamp engagements follow GHG Protocol Corporate Standard (for Scope 1 & 2) and GHG Protocol Corporate Value Chain (Scope 3) Standard. The company is led by GHG Protocol certified professionals. The GHG Protocol is the world's most widely used framework for measuring corporate greenhouse gas emissions and is specified by all UK procurement frameworks including PPN 006.
- UK Government DESNZ (formerly DEFRA/BEIS)coreThe Carbon Stamp uses UK Government GHG Conversion Factors published annually by DESNZ (Department for Energy Security and Net Zero, formerly DEFRA/BEIS) as the primary emissions factor source for all calculations. DESNZ factors are the official UK standard for SECR reporting, PPN 006 compliance, and all UK government procurement carbon requirements.
- ISO 14068 FrameworkcoreThe Carbon Stamp offers ISO 14068-1 aligned carbon neutral certification, the first international standard for carbon neutrality published in November 2023. The company delivers the five core ISO 14068 pillars: quantification (full Scope 1, 2 & 3 measurement), reduction plans, offset quality (Gold Standard/VCS/UN CER), transparency/public disclosure, and time-bound claims. Medicom Healthcare achieved ISO 14068-aligned carbon neutral certification through The Carbon Stamp.
- Gold Standard / Verra VCS / UN CER Carbon Offset RegistriescoreThe Carbon Stamp sources verified carbon offset credits from recognised registries — Gold Standard, Verra (VCS), and UN CER — for clients seeking carbon neutral certification. Credits must meet additionality, permanence, and verification requirements per ISO 14068. The company sources Gold Standard and VCS credits at £6.50/tCO₂e+VAT for clients. These are the most recognised standards in the voluntary carbon market.
- SECR (Streamlined Energy and Carbon Reporting)minorThe Carbon Stamp provides SECR reporting support for UK businesses required to comply with the Streamlined Energy and Carbon Reporting framework. SECR extends the former CRC Energy Efficiency Scheme and requires large UK businesses to report on energy use and carbon emissions. The company's SECR reporting service delivers a compliance-ready report template and support for SECR obligations.
- IPCC (AR5 / AR6)minorThe Carbon Stamp sources Global Warming Potential (GWP) values from IPCC Assessment Report 5 (AR5) and AR6, as published in DESNZ conversion factors, for calculating fugitive emissions from refrigerants and other greenhouse gases. GWP values convert all gases into a common tCO₂e unit for aggregation in carbon footprint calculations.
- B Corp Certification FrameworkminorThe Carbon Stamp supports B Corp certified companies (e.g., Wake The Tiger) with carbon footprint reporting aligned to B Corp sustainability assessment requirements. Services include verified GHG reporting across all scopes and net zero strategy development supporting B Corp Net Zero leadership commitments.
