Compare Cyber Essentials Certification Providers UK (2026)
Compare Assessment, Preparation, Plus Audits, Support, Renewal And Cost
Compare Cyber Essentials certification providers by IASME licensing, self-assessment support, scope guidance, Cyber Essentials Plus audit capability, technical remediation, assessor access, pricing, turnaround, retesting, renewal and service ownership. Evaluate providers against the same legal entities, devices, cloud services, controls and certification deadline before purchasing an assessment or supported package.
Certification Starts With An Accurate Scope
The certificate should represent the infrastructure, legal entities and cloud services that genuinely support the organisation’s business activity.
- Identify every legal entity and business unit included in the certificate
- Reconcile devices, networks, cloud services and internet-facing systems
- Justify exclusions and prove separation from the certified environment
- Keep every in-scope system supported and compliant on the issue date
Cyber Essentials is the UK Government-recommended minimum cyber security standard for organisations of every size. The scheme assesses five technical control themes: firewalls, secure configuration, security update management, user access control and malware protection. The standard level uses a verified self-assessment reviewed by a qualified assessor working for an IASME-licensed Certification Body.
Cyber Essentials Plus uses the same requirements but adds an independent technical audit. The auditor tests a representative sample of in-scope devices, every internet gateway and relevant internet-facing servers to verify that the declared controls operate in practice. The organisation must first achieve Cyber Essentials and normally progress to Plus within the permitted three-month window.
This page compares Cyber Essentials and Cyber Essentials Plus certification services only. It does not compare broader management-system or industry certifications. Providers may sell several assurance services, but the quote, assessor, readiness work, audit and certificate discussed here must remain specific to the Cyber Essentials scheme.
Choose The Right Assessment And Support Package
The official assessment price is standardised by organisation size, but provider support, technical remediation and Plus auditing vary significantly.
| Certification Route | What It Usually Provides | Best-Fit Question |
|---|---|---|
| Cyber Essentials assessment only | Provides the official assessment account and qualified review of the verified self-assessment | Is the organisation already compliant and able to interpret every question without consultancy? |
| Guided Cyber Essentials package | Adds assessor explanations, scope support, document review or limited advisory time to the official assessment | How much direct support is included, and does the assessor remain independent when marking the submission? |
| Turnkey readiness and certification | Adds discovery, gap analysis, remediation planning and hands-on preparation before assessment | Which technical changes are included, which remain the customer’s responsibility and what happens if the business is not ready? |
| Cyber Essentials Plus audit | Adds technical verification after successful Cyber Essentials certification using the same control requirements | Can the provider complete the audit within the three-month window and support the required device sample and retest? |
| Cyber Essentials and Plus combined package | Coordinates the verified self-assessment, readiness work and Plus audit under one engagement | Are both certificates, preparation, audit, retest and travel clearly separated in the proposal? |
| Renewal and continuous-readiness support | Tracks annual renewal, question changes, asset changes and control maintenance between certificates | Does the service improve ongoing compliance or merely remind the organisation to complete another questionnaire? |
| Sector or education-focused certification | Provides certification and preparation tailored to sector technology, procurement routes or shared services | Does sector experience improve the assessment without creating unsupported assumptions about the organisation’s own scope? |
| Certification with Cyber Advisor support | Combines an IASME Certification Body with NCSC-assured advisory help for SMEs needing practical control implementation | Which company provides the advice, which provides certification and how are conflicts and charges managed? |
Eight Areas That Determine Certification Readiness
Use the same scope and control evidence for every provider so fast-certification claims do not hide unsupported software, cloud accounts or incomplete device inventories.
Comparison Criterion
Firewalls And Internet Gateways
Confirm every boundary between in-scope devices and the internet, including routers, host firewalls and cloud controls. Review default credentials, inbound services, administrative access, approved rules and removal of unnecessary exposure. The Plus audit may test gateways and internet-facing services.
Comparison Criterion
Secure Configuration
Compare how the provider helps identify default accounts, unnecessary software, insecure services, weak settings, browser configuration and avoidable administrative access. Require a process that can be maintained across new devices and cloud services rather than one-off screenshots.
Comparison Criterion
Security Update Management
All in-scope software must remain supported. Under the current v3.3 requirements, high-risk or critical security updates and vulnerability fixes for operating systems, router or firewall firmware and applications must be installed within 14 days. The provider should verify inventory, ownership and exceptions before submission.
Comparison Criterion
User Access Control And MFA
Review account approval, unique identities, least privilege, administrator separation, leaver processes and authentication. MFA is mandatory for cloud services where it is available under the current requirements, including where a paid option must be enabled. Shared or unmanaged cloud accounts commonly create failure risk.
Comparison Criterion
Malware Protection
Assess anti-malware, application allow-listing, application sandboxing or other accepted protection methods across supported devices. Confirm central management, update health, mobile and non-Windows coverage, exclusions and how the organisation demonstrates that protections are active.
Comparison Criterion
Scope, Legal Entities And Cloud Services
Define every legal entity, business unit, location, device population, internet service and cloud service included. Cloud services processing or storing organisational data cannot simply be ignored. Exclusions require justification and effective separation from the certified scope.
Comparison Criterion
Verified Self-Assessment And Declaration
Compare portal usability, question guidance, assessor feedback, response time and evidence expectations. A board member or director signs the declaration, confirming that answers are accurate and acknowledging responsibility to maintain the controls during the certification period.
Comparison Criterion
Cyber Essentials Plus Technical Audit
Review discovery, external and internal testing, random device sampling, gateway testing, server checks, update verification, malware-protection tests, retest rules and operational preparation. The verified self-assessment must be final before Plus testing begins.
Measures To Define Before Buying A Certification Package
Translate fast, supported and audit-ready into measurable scope, control, timetable and ongoing-compliance outcomes.
| Measure | What It Should Define | Evidence To Request | Common Weakness |
|---|---|---|---|
| Scope reconciliation | Whether every declared legal entity, device, network, cloud service and internet gateway is represented accurately | Asset, identity, cloud and network inventories; exclusions; separation; owner; last review | The assessment uses an old device list that excludes remote workers and newly adopted SaaS services |
| Supported-software compliance | Whether every in-scope operating system, application, browser, firmware and security product is supported on the certificate date | Product, version, support status, end date, owner, upgrade and approved exception | A legacy application is kept in scope even though the operating system is no longer supported |
| Critical-update compliance | Whether high-risk and critical fixes are applied within the required 14-day period | Release date, risk rating, applicable assets, installation date, failure, owner and completion evidence | The organisation patches sampled devices but cannot prove consistent deployment across the scope |
| Cloud MFA coverage | Whether MFA is enabled for every user of every in-scope cloud service where it is available | Cloud-service register, users, MFA method, exceptions, paid feature, enforcement and monitoring | Microsoft 365 is protected while smaller SaaS accounts continue using passwords only |
| Administrative-access control | Whether privileged accounts are separate, limited, approved and reviewed | Administrator list, business need, unique account, authentication, review, leaver and dormant account | Daily email and web browsing are performed through unrestricted administrator accounts |
| Assessment return quality | Whether answers are complete, consistent and supported by the actual infrastructure | Assessor queries, returned questions, corrections, evidence, declaration and final approval | Consultancy text is copied into the portal without the organisation verifying that it is true |
| Plus audit readiness | Whether the declared scope can be sampled and technically verified without last-minute selective remediation | Device population, sample, gateways, servers, scans, test accounts, support contacts and readiness review | Only the expected sample devices are updated before the Plus audit |
| Certification timetable | Whether readiness, assessment, remediation and Plus audit complete before a tender or renewal deadline | Milestones, account expiry, assessor response, audit date, retest date, dependencies and owner | The business purchases certification shortly before a bid closes and discovers unsupported software |
| Annual control maintenance | Whether the five controls remain in place after the certificate is issued | Monthly asset, update, access and malware checks; change process; control owner; renewal readiness | Certification becomes a once-a-year project rather than an operational baseline |
| Total certification cost | The complete official assessment, support, remediation, Plus audit, retest and internal-effort cost | Organisation size, official fee, package, consultancy hours, audit, travel, retest, tools and renewal | A low assessment price is compared with a package that includes extensive technical remediation |

Review official Jisc certificationWhat Changes Cyber Essentials Certification Cost
The official standard assessment fee is transparent, but support, remediation and Cyber Essentials Plus auditing can materially change the complete budget.
| Cost Driver | Why It Changes Spend | What A Comparable Proposal Should Show |
|---|---|---|
| Official Cyber Essentials assessment | The standard verified self-assessment fee is tiered by organisation size rather than chosen freely by the provider | Micro 0–9 employees: £320 + VAT; small 10–49: £440 + VAT; medium 50–249: £500 + VAT; large 250+: £600 + VAT |
| Guidance and assessor support | Providers add different levels of portal help, calls, question review, evidence guidance and resubmission support | Included hours, response target, named contact, channels, excluded technical advice and additional hourly rate |
| Scope discovery and readiness review | Complex legal entities, cloud services, remote work, BYOD and segregated environments require additional analysis | Workshops, asset reconciliation, scope description, exclusions, legal entities, deliverables and customer tasks |
| Technical remediation | Unsupported software, missing MFA, patching, firewall, account and malware-protection gaps may require engineering before assessment | Exact changes, tools, licences, hours, supplier dependencies, testing, evidence and work excluded from the package |
| Cyber Essentials Plus audit | Plus pricing is quoted individually because device numbers, gateways, servers, locations and complexity influence audit effort | Certified scope, sample population, remote or onsite method, audit days, travel, testing, report, retest and deadline |
| Retesting and failed assessment | The verified self-assessment provides a limited correction period, while Plus audit retest rules and provider packages vary | Correction window, assessor remark, included retest, new sample, failed retest, rescheduling and reapplication charges |
| Multiple legal entities and certificates | The 2026 scheme supports clearer legal-entity identification and additional entity certificates within a wider certified scope | Entities, scope relationship, certificate count, additional certificate charge, ownership and procurement need |
| Tools, monitoring and policy templates | Some providers bundle device agents, compliance dashboards, policies, awareness or monitoring that are not part of the official assessment fee | Optional or mandatory status, users, devices, term, renewal, ownership, cancellation and value after certification |
| Travel and onsite audit | Cyber Essentials Plus can be delivered remotely or onsite, but premises, equipment and specialist environments may add cost | Locations, travel, expenses, onsite days, access, sampling constraints and cancellation terms |
| Annual renewal and price change | Certificates expire after 12 months and the organisation must complete a new assessment using the current question set | Renewal reminder, preparation, official fee, support price, uplift, Plus renewal, data reuse and cancellation |
How Readiness And Assurance Change The Shortlist
The right provider depends on current compliance, infrastructure complexity, certification deadline and whether independent technical verification is required.
Micro Business Already Meeting The Controls
Prioritise an assessment-only or light-support route, transparent official pricing, fast assessor communication and no compulsory software subscription.
SME Needing Practical Readiness Help
Prioritise scope workshops, asset and cloud-service reconciliation, direct technical guidance, clear remediation boundaries and a package that does not promise a pass without evidence.
Business Requiring Cyber Essentials Plus
Prioritise Certification Body capability for both levels, audit availability within three months, device-sample preparation, gateway and server testing, retest terms and operationally safe scheduling.
Education Or Complex Multi-Entity Organisation
Prioritise sector experience, legal-entity handling, detailed scope descriptions, cloud and shared-service understanding, multiple locations, structured evidence and predictable annual renewal.
How To Compare Certification Proposals
Give every provider the same employee count, legal entities, business units, locations, devices, networks, gateways, servers, cloud services, BYOD, remote-working model, current controls, Plus requirement and deadline. Require each quote to separate official fees, support, remediation and audit work.
- Current IASME Certification Body status is independently verified
- The proposed scope includes every relevant legal entity and cloud service
- Official fees and provider-added services are itemised separately
- Unsupported software, MFA and update gaps are identified early
- Plus audit sampling, timing and retesting are explicit
- Renewal, data export and cancellation terms are covered
Make Every Provider Review The Same Scope
Give each finalist the same device inventory, cloud-service register, legal entities, remote-working design, network boundaries and unsupported-software list.
Compare the questions they identify, the remediation they separate and the certificate scope they recommend before comparing package price.
Six Questions To Put To Every Certification Provider
The answers expose unlicensed intermediaries, incomplete scope, hidden consultancy charges and unrealistic certification deadlines before purchase.
Are You Currently Licensed By IASME?
Verify the organisation in the current IASME network directory and confirm whether it can deliver Cyber Essentials, Cyber Essentials Plus or both.
What Exactly Is Included In The Quoted Price?
Separate the official assessment, assessor support, scope review, consultancy, technical remediation, Plus audit, travel, retesting, tools and renewal.
How Will You Validate Our Certification Scope?
Ask how the provider reconciles legal entities, devices, BYOD, remote workers, cloud services, gateways, servers, exclusions and segregated networks.
Who Is Responsible For Making Technical Changes?
Confirm whether the provider only advises, performs remediation, coordinates an IT supplier or requires the customer to implement and evidence every change.
Can You Meet Our Plus Or Tender Deadline?
Request milestones for readiness, assessment submission, assessor feedback, certificate issue, Plus audit, remediation, retest and contingency.
What Happens At Renewal Or Exit?
Confirm annual preparation, current-question changes, records reuse, portal access, device software, subscription cancellation, data export and provider transfer.
A Seven-Stage Cyber Essentials Certification Process
Move from a verified business scope to maintained annual compliance rather than purchasing an assessment account before identifying control gaps.
- Confirm the commercial, contractual or risk reason for certification, the required level, the deadline and the accountable board or director sponsor.
- Inventory legal entities, business units, devices, networks, gateways, servers, cloud services, remote workers, BYOD and software support status.
- Assess the five technical controls against the current v3.3 requirements, including cloud MFA and 14-day high-risk or critical update requirements.
- Issue one written brief and obtain comparable official-fee, support, remediation, Plus audit, retest and annual-renewal proposals.
- Complete readiness work, approve the final scope, preserve evidence and ensure the declaration accurately reflects the organisation's real controls.
- Submit the verified self-assessment, respond to assessor questions and, where required, complete Cyber Essentials Plus within the permitted period.
- Maintain the five controls, review changes and prepare for recertification before the 12-month certificate expires.

Common Cyber Essentials Certification Mistakes
Most avoidable failures begin with an inaccurate scope, unsupported software, missing cloud MFA or a package comparison that mixes official fees with consultancy.
| Mistake | Why It Creates Risk | Better Control |
|---|---|---|
| Buying from an unverified intermediary | A reseller may offer support but cannot independently issue the certificate | Verify the licensed Certification Body |
| Comparing package price without separating the official fee | Assessment, consultancy, software and Plus audit become impossible to compare | Require itemised pricing |
| Using an incomplete device or cloud inventory | The declared scope does not reflect the organisation’s actual infrastructure | Reconcile assets, identities and cloud services |
| Excluding cloud services for convenience | Current requirements place organisational cloud services in scope | Map shared responsibility and apply controls |
| Keeping unsupported software in scope | Unsupported operating systems or applications cause assessment failure | Upgrade, replace or redesign the scope legitimately |
| Treating MFA as optional for smaller SaaS services | Cloud services where MFA is available can create an automatic failure | Enforce MFA across the complete cloud register |
| Patching only shortly before assessment | The organisation cannot demonstrate a maintained 14-day process | Operate measured update management throughout the year |
| Copying consultant answers without verification | The signed declaration may not match the real environment | Validate every answer with accountable owners |
| Booking Plus without readiness or time | Sampling and retesting can miss the three-month progression window | Complete a readiness review and contingency plan |
| Treating the certificate as permanent | Certification expires after 12 months and requirements can change annually | Maintain controls and plan recertification |
Frequently Asked Questions
Answers to common questions from UK businesses comparing Cyber Essentials and Cyber Essentials Plus certification providers.
What Is Cyber Essentials Certification?
Cyber Essentials is the UK Government-recommended minimum cyber security standard. It assesses five technical control themes: firewalls, secure configuration, security update management, user access control and malware protection. The standard certificate is issued after a qualified assessor verifies the organisation's self-assessment.
What Is The Difference Between Cyber Essentials And Cyber Essentials Plus?
Both levels use the same technical requirements. Cyber Essentials is a verified self-assessment, while Cyber Essentials Plus adds an independent technical audit of a representative sample of devices, internet gateways and relevant internet-facing servers. Plus provides a higher level of assurance.
Who Can Issue A Cyber Essentials Certificate?
A qualified Cyber Essentials assessor working for an IASME-licensed Certification Body can assess the submission and issue the certificate. Businesses should verify the proposed provider through the current IASME network directory rather than relying only on a reseller or consultancy claim.
How Much Does Cyber Essentials Cost In 2026?
The official Cyber Essentials assessment costs £320 plus VAT for 0–9 employees, £440 for 10–49, £500 for 50–249 and £600 for 250 or more. Provider guidance, technical remediation and Cyber Essentials Plus audits cost extra and should be itemised separately.
How Long Does Cyber Essentials Certification Take?
A prepared organisation may complete the questionnaire quickly, and assessors generally aim to return an initial result within a few working days. The complete timetable depends on scope, unsupported software, cloud MFA, patching, assessor questions and remediation. The assessment account normally remains available for six months.
How Long Is Cyber Essentials Certification Valid?
Cyber Essentials and Cyber Essentials Plus certificates are valid for 12 months. Organisations must recertify annually using the current requirements and question set. The signed declaration also confirms responsibility for maintaining the controls throughout the certification period.
What Changed In Cyber Essentials In April 2026?
Version 3.3 strengthened scope transparency, legal-entity information, cloud-service definitions, MFA and security-update requirements. MFA is mandatory for cloud services where available, and high-risk or critical fixes for operating systems, firmware and applications must be installed within 14 days.
Can Cloud Services Be Excluded From Cyber Essentials?
Cloud services that store or process organisational data or services are within the assessment responsibility and cannot simply be ignored. The cloud provider may implement some controls, but the applicant must understand shared responsibility, manage accounts and ensure the relevant Cyber Essentials requirements are met.
Does Cyber Essentials Plus Include A Penetration Test?
No. The Plus audit uses technical tests to verify the Cyber Essentials controls, including scans and sampling, but it is not a broad penetration test of business logic, attack paths or every application. A separate penetration test has a different scope and purpose.
How Should A UK Business Compare Cyber Essentials Providers?
Give every provider the same organisation size, legal entities, devices, cloud services, scope, control gaps, Plus requirement and deadline. Compare IASME licensing, official and added fees, support, remediation boundaries, audit availability, retesting, renewal and provider transfer.
