For many small firms, the answer decides whether they get shortlisted. A certificate gives buyers a simple, trusted sign that the basics are in place. Without one, you can lose out before anyone reads your proposal.

Here are the certificates worth knowing about, what each one involves, and what it can open up for your business.

1. Cyber Essentials

Cyber Essentials is the UK government-backed scheme, run by IASME with the National Cyber Security Centre. It is the most common starting point for small firms and the one buyers ask for most often.

It covers five areas:

• Firewalls
• Secure settings
• User access control
• Malware protection
• Security updates

What it opens up

• Many central government contracts require it, mainly where personal or sensitive data is handled.
• It is common in wider public sector tenders. It is also growing in private supply chains, where main contractors send security checks down to their suppliers.
• Law firms are often asked for it on panels and in referral deals.
• Eligible UK businesses can get cyber insurance included with it.

What changed in 2026

The current version, v3.3, came into effect on 27 April 2026. Two changes matter for most businesses:

• Multi-factor authentication (MFA) must be switched on for every cloud service where it is available, even where it is a paid extra. Not having it is an automatic fail.
• High-risk and critical security updates must be installed within 14 days of release. This covers operating systems, apps, firewalls and routers.

If your certificate is due for renewal, check both of these before you start. Many firms that passed before will not pass under the new rules without changes. Our free Cyber Essentials readiness checker takes a few minutes and shows where you stand.

2. Cyber Essentials Plus

Cyber Essentials Plus covers the same five areas, but an independent assessor tests your systems instead of relying on your own answers.

What it opens up

• Higher-value public sector and defence supply chain work often asks for Plus.
• It carries more weight in tender scoring because the controls have been checked.

Worth knowing

Under v3.3, if the assessor finds problems on the devices they test, a fresh random sample must be drawn to show the fix has worked. Getting your devices properly managed before the audit saves time and cost.

3. ISO 27001

ISO 27001 is the international standard for managing information security. It goes beyond technical controls. It covers risk, policies, suppliers and regular reviews across the business.

What it opens up

• Larger corporate clients, financial firms and overseas buyers often expect it.
• It can shorten or replace long security questionnaires.
• It shows long-term maturity, which helps in bigger multi-year contracts.

Worth knowing

ISO 27001 is a big job, with external and yearly audits. For most small firms, Cyber Essentials comes first. Holding ISO 27001 does not exempt you from Cyber Essentials where a contract asks for it by name.

4. Data Security and Protection Toolkit (DSPT)

The DSPT is a yearly self-assessment set by the Department of Health and Social Care. It is not a certificate in the usual sense, but for health and care providers it plays the same role.

Who needs it:

• CQC-registered adult social care providers in England
• Anyone with access to NHS patient data or systems
• Suppliers working directly for an NHS body

What it opens up

• Access to NHS.net Connect secure email, GP Connect, shared care records and Proxy Access
• Evidence for CQC under the Well Led key question
• Commissioners are advised to write DSPT at Standards Met into provider contracts. So it now affects who wins local authority and NHS work.

Worth knowing

The DSPT covers far more than IT. Paper records, staff training, verbal sharing and data sharing are all included. Your IT provider can supply the technical evidence, but the submission needs input from across the business. At least 95% of staff must complete yearly data protection training. Our Spot the Phish quiz is a quick way to test where your team is starting from.

5. Other standards to know about

Depending on your sector and clients, you may also come across:

• IASME Cyber Assurance: a step up from Cyber Essentials. It follows the same ideas as ISO 27001 but is built to be easier for small firms to reach.
• PCI DSS: needed if you take, store or process card payments.
• Lexcel: the Law Society’s practice management standard, which includes rules on handling information.
• ICO registration: not a certificate, but a legal must for almost every business that handles personal data. Buyers do check the public register. This matters for accountancy practices and anyone else holding client financial data.

How certificates help you win work

You pass the first filter. Many tenders are pass or fail on certificates. Without one, your pricing and experience never get read.

You score higher. Where security is scored, a recognised certificate earns marks a written answer cannot.

You answer security checks faster. Supply chain questionnaires can run to dozens of questions. A certificate covers many of them in one line.

You make insurance easier. Insurers now ask about MFA, patching and backups. A certificate gives you written answers. You can also check your email security in a few seconds.

You lower your real risk. The controls these schemes need, such as MFA, fast patching and malware protection, block the most common attacks on small businesses. Use our cyber risk cost calculator to see what an incident could cost your business.

Where to start

For most small firms the sensible order is:

1. Check you are registered with the ICO.
2. Get Cyber Essentials in place, and make sure MFA and 14-day patching are covered under v3.3. If you are not sure you will pass, start with a readiness assessment.
3. If you are in health or care, complete the DSPT to Standards Met.
4. Move to Cyber Essentials Plus once you are going after higher-value or public sector contracts.
5. Look at IASME Cyber Assurance or ISO 27001 when larger clients start asking for it.

The hardest part is not the assessment. It is keeping the controls in place all year, so renewal is routine and your evidence is ready when a tender lands. That is what Managed Cyber Essentials is for.

What Is ISO 27001?

ISO 27001 is an internationally recognised standard for information security management. In plain English, it’s a framework that proves your business takes the security of its data seriously and has the policies, processes, and controls in place to back that up.

Getting certified means an accredited body has independently audited your business and confirmed that your approach to information security meets the standard. It’s not a one-off tick box. It requires ongoing maintenance and regular reviews to keep the certification active.

What Does ISO 27001 Actually Cover?

The standard covers how your business manages information security across three areas:

People: Do your staff understand their responsibilities around data? Are there clear policies covering acceptable use, access controls, and what to do if something goes wrong?

Processes: Does your business have documented procedures for managing risks, handling incidents, and reviewing security regularly?

Technology: Are the right technical controls in place to protect your systems, devices, and data from unauthorised access or loss?

ISO 27001 doesn’t prescribe exactly what tools you use. It requires you to assess your risks and implement controls that are appropriate for your business.

Who Asks for ISO 27001?

Typically, larger enterprises, public sector bodies, and regulated organisations require their suppliers and partners to hold ISO 27001 certification before they’ll do business with them. If you’re trying to win contracts with NHS trusts, central government, financial institutions, or large corporates, there’s a good chance ISO 27001 will come up.

It’s also increasingly requested by cyber insurers as a condition of coverage, particularly for businesses handling large volumes of sensitive data.

Does Your Business Need ISO 27001?

The honest answer is: it depends on who you’re selling to and what data you handle.

You likely need ISO 27001 if:

• A current or prospective client has asked you for it directly
• You’re tendering for public sector or NHS contracts
• Your cyber insurer has raised it as a requirement
• You handle large volumes of sensitive personal or financial data
• You want to differentiate your business in a competitive market

You probably don’t need ISO 27001 right now if:

• Your clients are small businesses with no formal supplier requirements
• You’re an SME with under 20 staff and no regulated sector clients
• You haven’t been asked for it yet

For most small businesses in London, Cyber Essentials is the more appropriate starting point. It’s government-backed, faster to achieve, less expensive, and required for central government contracts. Many businesses treat it as the foundation before pursuing ISO 27001 as they grow.

How Long Does ISO 27001 Take?

For a small to medium business, the process typically takes between three and twelve months depending on how mature your existing security practices are. Businesses starting from scratch will need longer. Those who already have Cyber Essentials or documented security policies in place will move faster.

The process involves a gap analysis, implementing the required controls, internal audits, and a two-stage external audit by an accredited certification body.
