SimplISO › ISO 14001 certification cost
Straight answers, no quote formISO 14001 is rarely a business's first standard, and it should not be. Bolted onto a quality system that already works, it costs a fraction of what the quote forms imply. Here is the real arithmetic.
Written for UK businesses. Last updated 22 September 2026.
If you already hold ISO 9001, adding ISO 14001 costs about £2,050 in the first year through a non UKAS certification body, then about £1,700 a year after that.
From a standing start with no quality system in place, ISO 9001 and ISO 14001 together come to about £4,144 to first certificate.
The gap between those two numbers is the whole argument for building on ISO 9001 rather than starting again.
Every modern ISO management standard is built on the same skeleton, known as the Harmonised Structure (you may have heard it called Annex SL). Context of the organisation, interested parties, leadership, planning, support, operation, performance evaluation, improvement. The clause numbers line up almost exactly.
If you already run ISO 9001 properly, you have built most of ISO 14001 without knowing it. Document control, competence records, the internal audit programme, management review, corrective action and nonconformity handling all carry straight across. You do not build any of it twice.
That is why we ask clients to certify to ISO 9001 first and add the rest onto it. The quality system is the spine. Bolting ISO 14001 onto a spine that already works is a fraction of the effort of building a standalone system, and your certification body audits both in one visit rather than turning up twice and charging twice.
So the useful question is not what ISO 14001 costs. It is what ISO 14001 adds.
Four things move when you add a standard to a system you already run. Your subscription steps up a tier, your consultant internal audit has more ground to cover, the certification body audits the new standard once, and your annual surveillance goes up to match.
| What changes | Non UKAS body | UKAS accredited |
|---|---|---|
| SimplISO subscription | +£100 a month | +£100 a month |
| Consultant internal audit | +£200 a year | +£200 a year |
| Certification body, initial audit | £650 once | £1,700 once |
| Certification body surveillance | +£300 a year | +£1,200 a year |
| First year of the addition | £2,050 | £3,100 |
Every year after that, the addition costs about £1,700 through a non UKAS body, or £2,600 through a UKAS accredited one. That is the whole number. There is no separate consultancy invoice, no day rate and no set up fee.
Four things exist in ISO 14001 that have no equivalent in ISO 9001. Everything else is a rewording of something you already have.
Every activity you carry out, what it touches, and how much it matters. Air, water, land, waste, energy, noise. Each one scored so the significant ones rise to the top. This is the central new document and the one the auditor opens first.
A register of the environmental law that actually applies to you, with evidence you are meeting it. Waste duty of care, hazardous waste, packaging, WEEE, F gas, any permit or exemption you hold.
You have to think past your own gate, at least as far as you can control or influence. What you buy, how it is delivered, what happens to your product at the end of its life. It does not have to be a full lifecycle assessment, but it has to be considered and recorded.
What happens if a drum splits, a bund fails or a fire takes hold. A procedure, the kit to go with it, and evidence you have tested it rather than just written it down.
The compliance obligations register. Most small businesses go through it and find one or two things they should have been doing and were not. Waste transfer notes that stop three years ago. A hazardous waste consignment that never got registered. An F gas log that nobody has signed since the air conditioning was fitted.
That is not a reason to avoid ISO 14001. It is most of the reason to do it. Better to find it yourself with a consultant sitting next to you than to find it when an inspector arrives, and it is far better than finding it halfway through a tender.
ISO 14001 has two requirements that are pure people admin, competence and awareness. The SimplISO employee tools evidence both, so you are not building a second set of records by hand.
| Employee tool | What it evidences |
|---|---|
| Onboarding workflow | Clause 7.3 Awareness. Proof each person was made aware of the environmental policy, the significant environmental aspects their job touches, and what to do if something goes wrong. |
| Competence matrix and training log | Clause 7.2 Competence. For anyone whose work can cause a significant environmental impact, a record of what competence the role needs and that the person has it. |
| Annual reviews | Clause 7.2 again. The yearly check that competence is still current, recorded rather than remembered. |
Holiday booking is not an ISO requirement, and we would never pretend it is. It earns its place for a different reason. It is the thing your staff open the platform for every week, so while they are in there booking leave, the competence records and the training log stay current on their own instead of decaying quietly until an auditor asks to see them.
Worth being honest about this, because it decides whether the spend is worth it.
If none of those describe your customers, ISO 14001 is a genuine improvement to how you run but it is not a commercial necessity, and it is worth saying so rather than selling you something you do not need. If one of them does describe your customers, it usually pays for itself on the first bid you win.
Everything above assumes ISO 9001 is already in place. If you are starting from nothing and you know you need more than one standard, do them together. One programme, one set of documents, one audit visit.
| What you are certifying | Audit units | Months | To certificate |
|---|---|---|---|
| ISO 9001 on its own | 1 | 4 | £2,196 |
| ISO 9001 plus one other standard | 2 | 6 | £4,144 |
| ISO 9001 plus two others, or 9001 with 27001 | 3 | 8 | £6,492 |
| The full set | 4 | 10 | £9,240 |
An audit unit is one standard, with one exception. ISO 27001 counts as two, because its audit has to cover the Annex A controls as well as the management system. Our pricing calculator runs the same sum with UKAS switched on, and the ISO 9001 cost page breaks the single standard route down line by line.
We are still in our founding period, and the first fifteen registrants get 25% off the whole of their first year, locked in from the first invoice.
Considerably. The two standards share the same underlying structure, so your document control, competence records, internal audit programme, management review and corrective action process all carry across unchanged. Adding ISO 14001 to a working ISO 9001 system costs about £2,050 in the first year and £1,700 a year after that through a non UKAS certification body, against £4,144 to build both together from a standing start.
You can, and some businesses do, but we do not recommend it and we build every system on ISO 9001 first. On its own, ISO 14001 still needs the whole management system skeleton built from scratch, so you pay for all of it and get one standard out of it. Start with quality, add environmental onto it, and the second one costs you a fraction of the first.
A list of everything your business does that touches the environment, what the effect is, and how significant it is. Fuel use, waste streams, deliveries, chemicals, energy, packaging. Each is scored so you can show why you are focusing on some and not others. It is the central new document in ISO 14001 and it is usually the first thing an auditor asks to see.
Probably, and that is the point. The compliance obligations register is where most small businesses discover a gap, typically missing waste transfer notes, an unregistered hazardous waste movement or an F gas log nobody has kept up. Finding it during preparation with a consultant alongside you is a great deal cheaper than finding it during an inspection or a tender.
Only if your customers say so. UKAS accreditation is not a legal requirement. It costs about £1,700 against £650 for the initial audit of the added standard, and the yearly surveillance difference is wider still. Read the tender wording before you choose, because switching afterwards means paying for the audits twice.
Twenty minutes on a call and we will tell you what your certification body will charge, what the extra work looks like and whether you need UKAS at all.
