The list of the best ISO 27001 certification companies.
ISO 27001 certification costs can vary based on a number of factors. The consequences of getting these wrong means that costs can go up quickly and steeply.
The ISO 27001 certification costs are affected by
- The size of your organisation: The bigger you are the more the certification body will charge you. It is a simple as that. This one is outside your control of influence but be prepared for it.
- The scope of your ISO 27001 certification: You should spend time on defining your scope for certification including what is in scope and what is out of scope. The more that is in scope the more work you have to do and the more you need to be audited.
- The number of locations that are in scope: Once you have defined your scope work out how many locations are included. If they are your physical locations then an auditor will need to visit them. This will incur costs. More sites, more visits, more costs.
- The certification body you choose: Not all certification bodies are equal in what they charge. As a rule, the larger the certification body, the more they will charge. See more in the list of the best ISO 27001 certification companies.
Let us look at the typical ISO 27001 certification costs per country.
ISO 27001 Certification Cost UK
The typical cost for ISO 27001 certification in the United Kingdom (UK) is £8,000. This is the median of the small business costs. The cost of a UK ISO 27001 Certification is usually cheaper than international counter parts.
ISO 27001 Certification Cost Australia
The typical cost of Australian ISO 27001 certification is $15,000 AUD. This is the median of small business costs.
ISO 27001 Certification Cost USA
The typical cost of USA ISO 27001 certification is $12,000 This is the median of small business costs.
ISO 27001 Cost Breakdown
There are four categories of ISO 27001 Certification costs. They are:
- The cost of implementing ISO 27001 and building your Information Security Management System
- The cost of the actual ISO 27001 Certification and taking the test
- The cost of running the ISO 27001 Information Security Management System
- The ongoing annual cost of external certification audit
Implementation Costs
Putting in place the documents, templates, policies and processes of the management system and the associated controls will take a combination of time and money. Some of the costs are known and explicit. Some of the costs are hidden and implicit.
Either you are going to pay in your time to do it yourself or in money for someone to do it for you.
The costs for implementing ISO 27001 range from a few hundred pounds to buy an ISO 27001 toolkit with step by step guides to £/$10’s of thousands to get external help. The most expensive option is an ISMS Online Platform where costs range from £10,000 to £100,000 per year.
ISO 27001 implementation costs will vary considerably depending on if you use an ISO 27001 toolkit, employ someone full time, employ a contractor or engage a consultant.

Considering the approaches of doing it yourself, getting a contractor or employing High Table let us compare typical expected costs side by side.
| Do It Yourself | Consultant | Employee | Contractor |
|---|---|---|---|
| circa £500 | £5k to £15k | min £40k per year | £39k to £160k |
| 30 to 90 days duration | 5 to 15 days duration | 6 to 12 months duration | 3 to 12 months duration |

Surveillance Audit Costs
ISO 27001 Surveillance Audits are the annual audits that are performed to maintain your ISO 27001 certification. Every year up to your recertification audit the certification body will come back and perform a mini audit to ensure that the management system is still working.
The cost of the ISO 27001 Surveillance Audit is roughly 1/3 the cost of your certification audit.
Re-Certification Audit Costs
You will do a full re certification audit every 3 years. This is exactly the same as the ISO 27001 audit. The cost of the ISO 27001 re-certification audit is exactly the same as the ISO 27001 certification audit. You can expect to pay more due to the affects of inflation but the cost and process is exactly the same.
- Year 1 cost of £6,000 to £12,000
- Year 2 and year 3 cost of £2,000 to £5,000
- You then start the process over again and go back to Year 1.
On Going Costs
You would be forgiven for thinking that the costs for ISO 27001 end at certification. Sadly this is not the case. ISO 27001 is a management system that is based on continual operation and continual improvement. As a result of this there are several ongoing costs that you should consider. They include:
- Resource cost
There are many factors to consider but in brief, if you employ someone full time expect to pay £40,000 to £60,000 per year. If you outsource it expect to pay £12,000 to £36,000 per year. If you get an existing staff member to do it expect to pay training fees for them of around £2,000 to £5,000 per year.
- Annual recertification audit costs
To maintain the certification the certification body is going to audit you every year. It is actually a cycle of audits over 3 years but be prepared for audit costs for the next 2 years of around 33% of your year one cost. Then on the 3rd year you do the whole thing again from scratch with a full audit and at the full audit cost.
- Annual operational costs
The ISMS and associated controls have to be operated. This will come at a cost. The cost will either be in hiring new resources or in people’s time who will be diverted from their day job to complete the mandatory tasks required.
The biggest operational cost from the perspective of the standard will be the internal audit costs. I raise this here for special consideration as this is the one area that you are likely to require specialist resource that is independent of the areas being audited. Not only does the certification body audit you but you are expected to audit yourself on an ongoing basis. You can learn more about ISO 27001 Clause 9.2 Internal Audit to understand more on the requirement and read our guide on How to Conduct an Internal Audit to see what is involved and how you can do it yourself.
Mistakes People Make
- Not knowing what you need: The number 1 mistake most people make is not knowing what they need and what their options are. They get sucked in by fancy marketing. They believe the hype, that it is hard, when in fact it is not. They accept the high prices that are banded around without question.
- Not Shopping Around: The number 2 mistake most people make is not shopping around.An accredited certification is an accredited certification. Whilst you might belief the hype that they are not in it for profit, they are. The reality is costs vary wildly. Do your research. Get at least 3 quotes. Choose the ISO 27001 Certification Body that meets your finance requirements, your values and your needs.
