The cheapest, most cost effective way for a small business to implement ISO 27001 and get ISO 27001 certification is to do it yourself. They just do not realise that it is an option. It is.

It is not hard.

It is not complicated.

The costly mistake of not implementing ISO 27001 yourself

I am not saying that consultants, contractors or full time employees do not have their place.

They do.

If you use a contractor or a full time employee the costs can soon mount up. The main reason being that you are paying for their time irrespective of the outcome. We often see projects that should take 10 days stretch to 3, 6 and even 12 months.

Of the options of getting help it is our experience that working with a consultant on a fixed price basis is the most cost effective way to implement ISO 27001. The benefits are

  • Fixed and know cost
  • Often includes all required documentation and policies

ISO 27001 Certification Costs

ISO 27001 Certification costs are set by the certification body. To have meaning you will want a UKAS accredited certification. It is worth shopping around. The UKAS website lists all the accredited bodies.

The costs vary depending on your size and the ‘risk’ the certification body assigns to your business.

For a small business expect to pay £6k to £8k typical as a year 1 cost.

You then have on going yearly costs.

What will affect your ISO 27001 certification costs?

ISO 27001 certification costs can vary based on a number of factors. The consequences of getting these wrong means that costs can up quickly and steeply.

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. Read our How to Define ISO 27001 Scope as a guide.

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 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.

The on going costs of ISO 27001

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:

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 25% 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.

We are a small company, why does ISO 27001 cost so much?

Partly because the ISO 27001 standard has been built in such a way that it excludes small business on cost. The ‘official’ framework of certification bodies is bureaucratic and doesn’t take into account the size of your organisation. They work on audit days not company size. It is not designed to be in your favour but, as they say, it is what it is.

Do different ISO 27001 certification bodies charge different amounts?

Yes. They will tell you that they do not work on a day rate but they do. As a result, the number of audit days will be fairly consistent between the certification bodies but the rate they charge will differ. The product at the end, the ISO 27001 certification, is exactly the same. In fact they often outsource the certification audit itself to a small pool of independent contractor auditors. This means that irrelevant of who you pay you can end up with the same auditor and will get the same product and the same outcomes. Get at least 3 quotes and shop around. Whilst the standard is the standard the amount that you are quoted or charged will be different depending on the ISO 27001 certification body that you choose.

What can affect the ISO 27001 Certificaiton Costs?

The ISO 27001 certification costs are affected by
1. The size of your organisation
2. The scope of your information security management system
3. The risk that the certification body thinks your organisation is exposed to
4. The actual certification body that you choose

Why do different ISO 27001 certification bodies charge different amounts?

Different ISO 27001 certification bodies charge different amounts as they have different costs to account for. The amount that they pay their staff or consultants, the amount they charge for their processes, additional services that they provide, spend on marketing all contribute to the certification bodies charging different amounts.

Do ISO 27001 certification bodies use the same auditors but charge different amounts?

Yes, sometimes. The industry relies on a pool of freelance consultants to perform that ISO 27001 audits working for multiple ISO 27001 certification bodies at the same time. Sometimes a certification will have full time, permanent staff, usually in an attempt to reduce costs. You should ask when you engage with the ISO 27001 certification body what staffing model they adopt.
