What ESG reporting your business actually has to do
The average UK annual report runs to 98,000 words. The government put that figure in a press release on 6 September 2026, announcing it would scrap directors' reports and save business around £230 million a year. Six months earlier, on 25 February 2026, it published two brand new sustainability reporting standards.
More reporting, or less? Both. Which is why nobody in a finance team can say straight out what ESG reporting their business is obliged to do.
Whitehall is going in two directions at once
UK SRS S1 and S2, published on 25 February 2026, are the UK's versions of the international sustainability standards. The government's own guidance page says they are "available for voluntary use, by any entity that chooses to do so", and there is no effective date in them, because the final versions had their effective-date clauses taken out. The FCA has consulted on referencing them in the Listing Rules from 1 January 2027, which matters if you're listed and not if you aren't.
Streamlined Energy and Carbon Reporting is the one that already bites. It catches every quoted company and every large unquoted company or LLP, large meaning two out of three: turnover of £36 million or more, a balance sheet total of £18 million or more, 250 or more employees.
On 15 May 2026 the Department for Energy Security and Net Zero published its own post-implementation review of SECR, and the numbers are not flattering. Ongoing compliance costs business £140 million a year in 2025 prices against the £31 million predicted when the rules were made, a mean of £7,100 a year per complying business, and the same review puts actual non-compliance at 14 to 23 per cent. Its recommendation was to keep SECR, with amendments, subject to consultation.
Then there's the modernising corporate reporting consultation, opened on 7 September 2026 and closing on 30 November 2026, which among other things is testing the merits of non-financial reporting requirements for private companies. That phrase is doing a lot of work. It could mean less of all this, or a version of it for companies that have never had to think about it. Either way, if you're waiting for the picture to settle, you'll be waiting a long while.
The ESG reporting that reaches you comes from a customer
Here's the part that doesn't make the press releases. For most mid-sized UK businesses the first real demand for carbon numbers doesn't come from a regulator at all. It arrives on a procurement questionnaire, with a deadline, from a customer.
Procurement Policy Note 006, "Taking account of Carbon Reduction Plans in the procurement of major government contracts", applies to central government procurements advertised on or after 24 February 2025 where the contract is worth more than £5 million a year including VAT. It replaced PPN 06/21, which is still the number most online guidance quotes. A bidder has to publish a Carbon Reduction Plan on its own website: a commitment to net zero by 2050 for UK operations, current scope 1 and 2 emissions, a defined subset of scope 3, all in CO2e, plus the environmental management measures in place.
Publish is the operative word. The plan sits in public, where that bidder's own suppliers can be asked to match it. Which is how a rule aimed at £5 million government contracts lands on the desk of a company with forty staff and no reporting obligation of its own. Your customer isn't inventing work for you. They're passing on a condition of theirs.
Three things worth doing before December
None of this needs a consultant on day one.
First, work out which regime you're in, on one page. Three questions: are you quoted, do you meet two of the three SECR thresholds above, and do any of your significant customers hold public sector contracts? Three noes means no legal obligation today and a commercial one on the way. Write it down, date it, put it in the board pack. Much of the cost here is people guessing.
Second, measure scope 1 and 2 once, using the free route before the paid one. The UK Business Climate Hub at businessclimatehub.uk is the UK partner of the SME Climate Hub, its policy content is reviewed by DESNZ, and it points at a range of free tools, checked on 27 October 2026. A first measurement should cost nothing like the £7,100 a year the May 2026 review puts on full SECR compliance.
Third, write the plan in the PPN 006 format even if you'll never bid for a government contract. Not because you have to, but because it's the format your customers' procurement teams already recognise, and answering the same question four ways for four customers is where time disappears.
One honest warning. The moment you measure you'll find something you'd rather not know. That's rather the point, and it's the same argument as the case for management accounts: better you find it in November than a buyer does in February.
Most of what moves the number costs capital: lighting, vehicles, insulation, newer plant, a heat pump. That's where this stops being a reporting exercise and becomes a funding question, the half that gets left until after the deadline. The British Business Bank's guidance on green loans for smaller businesses is a sensible, non-commercial place to start, though its page carries no date. For the equipment itself the usual question is asset finance or invoice finance, and if a bank has said no to the spend, a declined application has more life left in it than most people think.
We're a commercial finance broker rather than a lender, and Pathfinder isn't directly FCA authorised, we work through authorised partners. We're also a certified B Corp, so we've been through a version of this measurement rather than only writing about it.
The government reckons scrapping directors' reports will save business around £230 million a year. Its own review says the carbon rules it already has cost £140 million a year, and recommends keeping them. Nobody is coming to simplify this. Your customer's procurement portal, on the other hand, has a deadline, and that one is real.
