ESG Compliance in London

Serving London and the wider Greater London area, including Croydon, Bromley, Watford.

ESG compliance in London starts with one question: do you legally have to report?

For a London business, ESG compliance is not a single certificate you either hold or you don’t. It is a stack of overlapping duties, and the first job of a specialist is to tell you honestly which of them actually bind your company. The headline duty for most mid-to-large firms in the capital is Streamlined Energy and Carbon Reporting (SECR), which requires quoted companies, and large unquoted companies and LLPs, to disclose their energy use and greenhouse gas emissions in the directors’ report filed with the annual accounts. “Large” is the Companies Act test: you are caught if you meet at least two of three thresholds — 250 or more employees, turnover over £36 million, or a balance-sheet total over £18 million. London is where more of those companies sit than anywhere else in the UK, and plenty of private groups cross the line after a good year or an acquisition without ever thinking of themselves as “reporters”, which is exactly where the surprises start.

Sitting above SECR for the largest companies are mandatory TCFD-aligned climate-related financial disclosure under the Companies (Strategic Report) (Climate-related Financial Disclosure) Regulations 2022, and, increasingly, a Carbon Reduction Plan to win major public-sector contracts under Procurement Policy Note 006. On the horizon are the UK Sustainability Reporting Standards (UK SRS S1 and S2) — the UK’s version of the ISSB baseline, which the government finalised for voluntary use in early 2026 but has not made mandatory, and which remains under active consideration by government and the FCA. We build a London company’s programme on the duties that bind it today, structured so that adopting UK SRS later is an extension rather than a rebuild. Anyone telling you UK SRS is already compulsory is overstating it.

This page sets out how that plays out for a company headquartered in, or operating across, Greater London — the city’s net-zero policy your customers and your council are working to, the local anchor institutions whose tenders now demand a carbon plan, and how our ESG compliance programme for London firms applies from a first SECR baseline through to a net-zero roadmap.

London’s 2030 net-zero target and what it means for reporters in the capital

London runs on one of the most aggressive decarbonisation timetables in the country, and that raises the bar on ESG expectations for every business here. The Greater London Authority, led by Mayor Sadiq Khan, has brought London’s net-zero target forward from 2050 to 2030 — twenty years ahead of the UK’s statutory 2050 date and among the most ambitious of any major global city. It sits within the London Environment Strategy and is delivered through the Mayor’s chosen “Accelerated Green” pathway, which envisages more than 250,000 non-domestic buildings being properly insulated and around 2.2 million heat pumps in operation across the capital by 2030. Each of the 32 London boroughs and the City of London Corporation carries its own climate framework beneath that pan-London target.

For a company sitting inside that policy environment, the direction of travel is one-way. A city-wide 2030 target does not itself create a legal reporting duty on your business — SECR and TCFD-aligned disclosure are national regulations, not municipal ones — but it shapes the commercial context in three concrete ways. It drives the capital’s public bodies to push carbon requirements down their supply chains (see the tender section below). It underpins genuine building-decarbonisation support, particularly for the vast non-domestic estate the strategy targets. And it means London customers, investors and lenders — a great many of them the very institutions doing the lending — increasingly probe whether your reported numbers, and the plan behind them, are credible. Getting ahead of that is a hedge, not a gamble.

We are clear about the boundary between the city’s support offer and what a reporting-obligated company actually has to file. GLA and borough programmes, and the London Plan’s Policy SI 2 requirement that major new commercial development be net-zero-ready, are genuinely useful context for planning a decarbonisation programme. But they do not produce the assurance-ready SECR disclosure, the TCFD-aligned climate statement, or the PPN 006 Carbon Reduction Plan that a London company caught by the rules has to produce. Those are delivered professional services, and that is the half of the job we own.

Who actually has to report in London

The clearest way to understand SECR and TCFD scope in London is to look at where the reporting-obligated companies actually cluster. London’s economy is by some distance the largest of any UK city region — its gross value added runs to several hundred billion pounds a year, dwarfing the next-largest city economies — and its business base contains more quoted and large companies than the rest of the country combined.

The City of London — the Square Mile — and Canary Wharf together form the densest concentration of TCFD-in-scope firms anywhere in the UK: the FTSE 100 and FTSE 250 banks, insurers and asset managers headquartered there are squarely within both the SECR regime and mandatory TCFD-aligned climate disclosure, and many are already preparing for whatever the FCA decides on UK SRS. Beyond financial services, Stratford and the Queen Elizabeth Olympic Park have drawn corporate and public-sector headquarters east; Old Street and the surrounding tech cluster host high-growth companies that cross the SECR thresholds as they scale; and industrial London — Park Royal, one of Europe’s largest industrial estates, straddling Ealing, Brent and Hammersmith & Fulham, plus the Old Kent Road and Greenwich Peninsula — houses the large logistics, food-production and manufacturing operators that the SECR “large company” test is designed to catch.

The point for a Head of Sustainability or Finance Director reading this is not that these particular businesses need our help — it is that London’s business base is full of companies that either already report or are one growth year away from having to. If your company is quoted, or if you meet two of the three “large” thresholds, the energy and carbon disclosure goes in your directors’ report and is filed with your accounts at Companies House. It has a hard deadline, and a vague sustainability page does not satisfy it. We tell you precisely where you sit before we quote a thing.

Decarbonisation, the grid and honest levers in London

Reporting is only half the job. The other half is the decarbonisation roadmap — the costed, sequenced plan that actually makes next year’s numbers better than this year’s — and here the local context is the electricity network your sites sit on. The Distribution Network Operator for London is UK Power Networks, which runs the distribution network across London, the South East and the East of England. That matters the moment a roadmap recommends on-site generation.

We treat renewables honestly, as a lever rather than the product. On-site solar or a well-structured power purchase agreement (PPA) can reduce your market-based Scope 2 emissions — the figure that reflects the electricity you have specifically contracted for under the GHG Protocol’s dual Scope 2 method. There are two honest caveats a London company needs to hear up front, and they bite harder in the capital than almost anywhere. First, it only touches Scope 2: it does nothing for your Scope 1 fuel use or your Scope 3 value chain, which for a London office-based or financial business is very often the overwhelming majority of the footprint. Second, dense-city rooftops are frequently constrained — heritage constraints in the City, limited south-facing roof area, and landlord consent on multi-let buildings — so a PPA or a genuinely additional off-site array is often more realistic than a rooftop install. Where a roadmap does recommend on-site generation, the grid-connection notification to UK Power Networks (a G98 notification for small installs, G99 for larger) applies to that measure, downstream of the reporting itself, never as part of the disclosure.

That distinction — reporting first, decarbonisation as the delivery half, renewables as one honest lever inside it — is the whole discipline. It is what keeps a London company’s net-zero claims clear of a greenwashing challenge under the CMA’s Green Claims Code, and it is why we never dress a solar install up as an ESG strategy.

ESG in London’s tenders: the anchor institutions raising the bar

For many London businesses, the trigger to act on ESG is not a filing deadline at all — it is a lost bid. The capital’s large public and anchor institutions have moved carbon requirements firmly into their procurement, so a supplier without a credible carbon footprint and reduction plan is increasingly shut out of work it would otherwise win.

The Greater London Authority and Transport for London — one of the largest transport procurers in Europe — both apply responsible-procurement and carbon requirements to their supplier base. Across higher education, University College London and Imperial College London, two of the country’s biggest research institutions, operate sustainable-procurement and supplier-engagement programmes that push Scope 3 expectations onto anyone wanting to trade with them. The 32 London boroughs apply social-value and carbon criteria to their own contracts. And across the health economy, London’s NHS trusts sit within the national NHS Net Zero Supplier Roadmap, under which suppliers must complete the Evergreen Sustainable Supplier Assessment and, from 6 April 2026, hold a PPN 006-compliant Carbon Reduction Plan at Level 1 to tender through NHS Supply Chain.

That national procurement rule, PPN 006 (which updated the former PPN 06/21 to reflect the Procurement Act 2023), requires suppliers bidding for major central-government contracts worth more than £5 million a year including VAT to have and publish a Carbon Reduction Plan confirming a commitment to net zero by 2050. Beyond that central-government threshold, the selection questionnaires used by London’s public bodies increasingly ask for your footprint, your reduction targets and your environmental-management arrangements as a matter of course. The practical reality for a London supplier is simple: a missing Carbon Reduction Plan can disqualify an otherwise winning bid, and getting one in place is a commercial move, not a green gesture.

Our ESG services, applied across London

We deliver the whole programme rather than a directory of frameworks or a free online checker. For a London company, that runs across five connected services, each of which we apply to your actual sites and data across the capital and the wider South East.

• ESG strategy and materiality — a materiality (or double-materiality) assessment and the governance layer that a TCFD-aligned disclosure and the emerging UK SRS both expect you to describe. For a City or Canary Wharf financial firm, this is where a first regulated climate disclosure begins.
• Carbon footprint and baseline — a Scope 1 and 2 greenhouse gas inventory built to the GHG Protocol Corporate Standard, using the UK government’s conversion factors, with both location-based and market-based Scope 2 figures. This is the starting line for a London site, whether it is a Square Mile office floor or a Park Royal industrial unit.
• SECR reporting — the disclosure that goes into your directors’ report and is filed with your accounts, prepared to stand up to scrutiny and, where you want it, to independent assurance. This is the money page for a company searching for ESG reporting help.
• Net-zero roadmap — a costed, sequenced plan with SBTi-aligned targets, energy efficiency first and on-site generation or a PPA treated as an honest Scope 2 lever, aligned to both the statutory 2050 target and a PPN 006 Carbon Reduction Plan.
• Scope 3 and supply-chain emissions — value-chain emissions across the fifteen GHG Protocol categories, spend-based screening to find the hotspots first, then supplier-specific data where it moves the number. For a London services or financial business, this is usually where the real footprint lives.

Every engagement is scoped on the shape of your business — how many sites and meters are in the inventory, how mature your data is, and above all whether Scope 3 is in scope — not priced off a menu, because a headline figure would mislead you.
