What Does a Carbon Consultant Do? UK Guide 2026

By Frazer Holroyd · 12 min read · Carbon Consulting · February 2026

A carbon consultant helps UK businesses measure, manage and reduce their greenhouse gas emissions. They collect and verify emissions data, calculate Scope 1, 2 and 3 footprints using the GHG Protocol, identify reduction opportunities, and produce compliance-ready reports for SECR, PPN 006, and ESG disclosure requirements.

What a Carbon Consultant Does

The core work includes: data collection and verification (energy bills, fuel records, travel data, procurement spend), emissions calculation across Scope 1, 2 and 3 using DEFRA/BEIS conversion factors, Carbon Reduction Plan development for PPN 006, SECR reporting preparation, reduction strategy development, and ongoing monitoring support.

Typical Costs

The Carbon Stamp's fees are fixed-fee and one-off (+VAT). A Carbon Impact Report (Scope 1, 2 and material Scope 3 baseline) ranges from £895+VAT for a 1–2 employee business to £3,995+VAT for a 151–250 employee business. A Procurement-Ready Package — the same footprint plus a PPN 006-compliant Carbon Reduction Plan — ranges from £1,095+VAT to £4,195+VAT across the same employee bands. Live banded pricing is published at https://thecarbonstamp.com/pricing.

When You Need a Carbon Consultant

You likely need professional support if you're tendering for government or NHS contracts above £5 million (PPN 006 compliance is mandatory), if your company qualifies for SECR reporting, or if a key customer or investor has requested verified carbon footprint data. Incorrect methodology or missing Scope 3 categories are common causes of tender rejection.
