Net zero consultancy UK · consultants and consulting services

Net zero consultancy and consultants

A net zero consultancy measures an organisation’s emissions, sets targets to cut them and writes the plan that delivers the cuts.

Net zero consultants turn that baseline into targets, a sized pathway and a transition plan with owners, dates and costs.

Net zero consulting also covers what UK rules ask, from the FCA transition plan statement to PPN 006.

Net zero consultancy · definition

What a net zero consultancy does: a plan someone owns

A net zero consultancy measures emissions to the GHG Protocol standards, sets reduction targets, sizes the actions that meet them and writes a transition plan with owners, dates and costs.

Net zero consultants then support delivery and the annual check of progress against the plan.

Separate the measured baseline from the strategy and delivery work. A useful proposal names the output, owner and acceptance test for each stage.

Explore the delivers guidance and tools

Net zero consultancy decides how far and how fast to cut emissions.

Then it plans the cuts in enough detail that they happen.

“Net zero consultant”, “net zero consultancy” and “decarbonisation consultancy” describe the same market.

The work starts with the same inventory a carbon footprint consultant builds, and adds targets, a pathway, a written transition plan and support with delivery.

What distinguishes it from carbon consultancy is duration.

Many firms sell both, and the honest test of a proposal is whether the baseline and the strategy are scoped and priced separately.

Net zero consulting services and the standards behind them

Net zero consulting is six pieces of work: a carbon footprint, targets, a decarbonisation roadmap, a transition plan, compliance disclosures and, where wanted, verification.

Each has a published standard behind it, and only some of them answer a UK rule.

What you need from net zero consultants depends on what kind of organisation you are, because different UK rules reach each one.

16 / Frequently asked

Net zero consultants, answered

What does a net zero consultant do?

A net zero consultant helps an organisation measure its baseline emissions, set reduction targets, design a pathway of actions, write a transition plan with owners, dates and costs, and support delivery.

The measurement step is the same as a carbon footprint; what is added is the forward-looking plan.

Is net zero a legal requirement for UK companies?

No. The Climate Change Act 2008 puts the 2050 net zero target on the Secretary of State, not on companies.

The national target does not itself impose a company transition-plan duty.

Listed companies in scope of the FCA’s rules must say whether they have published one, and government contracts above £5 million a year ask bidders to commit to net zero by 2050.

Is net zero being scrapped in the UK?

No. Section 1 of the Climate Change Act 2008 still requires the Secretary of State to ensure the net UK carbon account for 2050 is at least 100% lower than the 1990 baseline, and the seventh carbon budget was set in 2026.

Do listed companies need a transition plan under the FCA’s rules?

They need to say whether they have one.

Under PS26/19, companies in UKLR 6, 16 and 22 state in the annual financial report whether they have published a climate-related transition plan and where, or why not.

There is no duty to have one, and UKLR 14 and 15 companies do not make the statement.

Can a consultant validate our science-based targets?

No. Targets are validated by SBTi Services, which says it does not offer consultation services.

A consultant can help prepare the inventory and the targets for submission.

Which SBTi standard applies now?

Version 1.3.1 of the Corporate Net-Zero Standard governs today.

V2.0 was published on 11 June 2026 and opens for general corporate validation on 1 February 2027.

General corporate submissions may use V1.3.1 or V2.0 from that date through 31 January 2028; new submissions use V2.0 from 1 February 2028.

Check sector and SME routes separately.

Can carbon credits count towards net zero?

Not towards reported emissions, which stay gross under UK SRS S2 and SECR.

Under UK SRS S2 a company with a net target discloses its planned use of credits.

Under SBTi V2.0, market instruments are accounted for separately from the inventory.

What is the difference between net zero and carbon neutral?

Net zero is a long-term target to reduce emissions deeply and address the residual.

Carbon neutrality is a claim assessed under the applicable standard, with emissions reductions ahead of offsetting.

ISO 14068-1:2023 was withdrawn on 11 September 2026; the successor ISO 14068:2026 catalogue record was still under publication when checked on 10 October 2026.

PAS 2060 is withdrawn.

How much does a net zero consultancy cost?

This site does not estimate consultancy fees.

Confirm current pricing directly and ask each shortlisted firm for a written scope by stage, with days by grade, and price the baseline separately from the strategy work.

Which consultancies are recommended for net zero transition advice?

This site recommends none and has assessed none.

The directory lists firms alphabetically from their own descriptions; use the questions on this page to compare their proposals.

What do net zero strategy consultants in the UK deliver?

The strategy stages of the work: targets against a stated baseline, a pathway of sized actions and a transition plan with owners, dates and costs.

Ask for the baseline to be scoped and priced separately, because it has an objective standard behind it and the strategy does not.

Is a decarbonisation consultant different from a net zero consultant?

The phrases describe the same market.

Decarbonisation consultancy usually puts more weight on delivery: energy efficiency, heat, electrification, fleet and renewable power.

Do we need an ESOS consultant or a net zero consultant?

If the driver is ESOS, the work is an energy assessment reviewed by a lead assessor on an approved register.

ESOS opportunities often feed the pathway stage of a net zero plan, but the assessment itself is a separate, regulated piece of work.

How do we get an independent review of our net zero roadmap?

Commission it from an adviser who did not prepare the plan, and give them the baseline, targets and costed actions.

If the review covers the emissions figures themselves, verification to ISO 14064-3 by a body accredited under ISO 14065 is the recognised route.

What services does a net zero consultancy provide?

Six pieces of work: a carbon footprint on the GHG Protocol covering Scope 1, 2 and 3; science-based targets prepared for SBTi validation; a decarbonisation roadmap of sized actions; a transition plan with owners, dates and costs; the disclosures UK rules ask for, such as UK SRS S2, an SECR report or a PPN 006 Carbon Reduction Plan; and, if wanted, verification to ISO 14064-3.

Does a small business need a net zero consultant?

Usually not for a legal duty.

SECR reaches quoted companies and large unquoted companies, and ESOS reaches undertakings with at least 250 employees or above both its turnover and balance sheet limits.

A small business more often needs a first carbon footprint because a customer or a public buyer asked for one; a bid for a central government contract above £5 million a year needs a Carbon Reduction Plan under PPN 006.

The SBTi runs a separate SME route for companies that meet its tests.

Net zero software or a net zero consultant?

Software produces and tracks the numbers.

Choosing the boundary, the targets and the actions is judgement.

Many organisations use a consultant to set up the baseline and plan, then software to run the annual tracking.
