How to get SIA approved contractor status

SIA Approved Contractor status is a voluntary accreditation from the Security Industry Authority that lets private security firms prove they meet a national quality standard. To get it, a company applies to the SIA, scores itself against a 78-indicator self-assessment workbook, pays an application fee of £400–£2,400, and passes an independent verification visit by a UKAS-accredited assessor such as SSAIB.

Key Takeaways

• SIA Approved Contractor Scheme (ACS) status is assessed against 78 indicators scored out of a maximum of 145 points, according to ProFM Group (2026).
• Around 700 companies held ACS approval as of July 2026, meaning roughly 105 firms sit in the top-15% Pacesetters band, per ProFM Group (2026).
• ACS application fees range from £400 to £2,400 depending on company size, plus assessor fees and an annual per-licensable-individual registration charge, according to Coredinate (2026).
• The SIA's per-licensable-individual fee rises from £15 to £25 from 1 June 2026, per Security Matters Magazine (2026).
• Approved contractors can deploy up to 15% of their workforce under a licence dispensation notice while applications are processed — an option closed to firms without ACS status, according to SSAIB (2026).

What is SIA Approved Contractor status?

SIA Approved Contractor status is a voluntary accreditation issued by the Security Industry Authority (SIA) — the statutory regulator for the UK private security industry — that certifies a security company meets a defined operational and quality standard under the Approved Contractor Scheme (ACS). It exists alongside, not instead of, individual SIA licensing: every door supervisor, security guard or CCTV operator still needs a personal SIA licence, but ACS approves the company as a whole.

The legal basis sits in sections 14 and 15 of the Private Security Industry Act 2001, which gives the SIA power to run approval schemes for businesses supplying security services. Approval is not compulsory — but for many buyers, particularly public-sector procurers and managing agents in the City of London and Canary Wharf, it has become a de facto entry requirement.

The scheme covers a business against seven criteria, broken into 33 sub-criteria and 78 individual indicators, each scored against a required baseline and additional points for evidenced good practice — a structure Pulse Operations sets out in full in its own guide, The ACS self-assessment: how to evidence it.

How ACS differs from individual SIA licensing

An SIA licence is issued to a named individual — a door supervisor, security officer or CCTV operator — and confirms they have passed background checks and completed mandatory training. ACS approval is issued to the company employing them and confirms the business itself runs to a national standard covering strategy, service delivery, financial management, resourcing, people and leadership. A firm can employ fully-licensed officers without ever holding ACS status; ACS is the layer above individual licensing that assesses the organisation.

How do I check eligibility before applying for ACS?

Eligibility for SIA Approved Contractor status depends on trading history, financial stability and the nature of the services supplied, not company size. A business typically needs at least one full year of trading accounts, a clean financial standing check, and evidence it supplies licensable security services as defined under the Private Security Industry Act 2001. There is no minimum headcount, so sole traders and large national providers apply against the same standard.

Before submitting anything to the SIA, most operators use the ACS Self-Assessment Workbook (SAW), the SIA's own interactive tool for scoring a business against the standard. The workbook is scored out of a maximum of 145 points — reduced by 30 points from the previous SAW version, according to SGC Security Services (2026) — across 78 indicators grouped into seven criteria: Strategy, Service delivery, Commercial relationship management, Financial management, Resource management, People, and Leadership.

The seven ACS criteria at a glance

The People criterion is where assessors spend disproportionate time, because it checks how rigorously a contractor applies BS 7858, the British Standard for security screening, and whether every deployed licence is verified against the SIA's public register.

What is the standard route versus the passport route to ACS?

The Standard Route is the default path to SIA Approved Contractor status: a company self-assesses using the SAW, submits an application, and undergoes a full on-site verification visit by a UKAS-accredited assessing body. The Passport Route is a faster alternative available to firms that already hold an equivalent, SIA-recognised third-party quality certification, letting them carry some evidence across rather than rebuilding it from scratch — per the National Business Crime Centre guidance on becoming an approved contractor.

For most first-time applicants without an existing accreditation to leverage, the Standard Route is the only realistic option. It's also the more thorough test: assessors review staff files and payroll records, contracts and duty rotas, policies and procedures, and site documentation; they interview staff and customers; and they physically visit operational sites, as detailed in Pulse Operations's guide, The ACS self-assessment: how to evidence it.

Choosing an assessing body

The SIA does not carry out verification visits itself. Instead, applicants choose from a small number of UKAS-accredited certification bodies, including SSAIB, NSI (the National Security Inspectorate) and the British Assessment Bureau. All assess against the same ACS standard, but timelines, assessor availability and sector familiarity vary — a firm running static guarding across shopping centres may want an assessor with retail-security experience; a construction-security specialist may prefer one used to site-hoarding and welfare-check environments.

How much does it cost to get SIA approved contractor status?

Getting SIA Approved Contractor status costs between £400 and £2,400 in application fees depending on company size, plus a separate assessor fee charged by the UKAS-accredited body carrying out the verification visit, according to Coredinate (2026). On top of that, approved contractors pay an annual registration fee per licensable individual deployed — a fee rising from £15 to £25 from 1 June 2026, per Security Matters Magazine (2026), which cites GOV.UK.

The registration fee is the one cost every ACS holder underestimates. A mid-sized contractor deploying 80 licensed officers will see its annual registration bill roughly climb in line with the £15-to-£25 rise — a material jump for firms budgeting on old figures. Factor the new rate into any tender pricing or renewal budget for periods after 1 June 2026.

Ways to reduce the cost and effort of ACS

• Start the SAW self-assessment early, months before submitting, so gaps in evidence surface while there's time to fix them rather than during the verification visit.
• Centralise records now — staff files, training certificates, licence numbers, incident logs — rather than scrambling across spreadsheets and filing cabinets when the assessor's visit date is confirmed.
• Use the Passport Route if the business already holds a recognised equivalent certification, to avoid duplicating evidence-gathering.
• Budget for the 1 June 2026 fee rise in any renewal or tender pricing calculated before that date.
• Automate what can be automated — rostering, licence-expiry tracking, screening records — so evidence exists as a by-product of daily operations rather than a annual reconstruction project.

How do I prepare for the ACS verification visit?

Preparing for an ACS verification visit means ensuring day-to-day operational records already match what the self-assessment workbook claims — not building a paper trail retrospectively. Assessors interview staff and customers, visit live sites, and cross-check rosters against payroll and training records against personnel files. A mismatch between what the workbook says and what the evidence shows is the most common reason firms fail or are asked to resubmit.

"SIA Approved Contractor status isn't won by writing good policies, it's won by proving your paperwork matches what actually happens on site. Assessors want to see rosters, training records and incident reports that line up with reality, not a folder built the week before the audit. Get your everyday systems right first — the accreditation just confirms what's already true." — Mo Hassan, Founder, Pulse

This is precisely why operators increasingly run compliance as a live system rather than an annual project. Pulse Operations's compliance runway tracks SIA licence expiries, BS 7858 screening records, DBS checks, right-to-work documents and training certificates on a single expiries timeline — so the evidence an ACS assessor asks for already exists, dated and attributable to a named officer, rather than being assembled retrospectively.

At Priority First — the founding team's own London security & FM operation, disclosed here because Pulse was built inside it before being offered to other operators — a landmark West London mixed-use development runs 152 checkpoints across retail units, residential cores, plant rooms and service yards with 11 officers. Every checkpoint is completed by a mandatory watermarked photograph rather than a tag scan, producing over 540 photographed patrols in the first five months live. That kind of granular, timestamped record is exactly the operational evidence an ACS assessor cross-checks against the People and Service delivery criteria — proof the site was actually walked, not just scheduled.

Common reasons verification visits fail

• Staff files missing signed BS 7858 references or gaps in employment history checks
• Rosters that don't reconcile with actual hours paid through payroll
• Licence numbers not checked against the SIA's public register before deployment
• Policies that exist on paper but that frontline staff can't describe when interviewed
• No documented process for handling client complaints or service failures

What is ACS Pacesetters status and how is it different?

ACS Pacesetters status is a higher tier awarded only to the top 15% of companies within the ACS scheme, based on their self-assessment workbook score, according to ACS Pacesetters (2026). With roughly 700 companies holding standard ACS approval as of July 2026, only around 105 qualify for Pacesetters status, per ProFM Group (2026) — making it a genuine differentiator in competitive tenders rather than a marketing label.

Because the maximum achievable SAW score is 145 points, reaching the Pacesetters threshold means scoring near the top of that scale consistently across all seven criteria, not excelling in one area while carrying weak evidence elsewhere. Firms chasing Pacesetters status typically need the same underlying discipline that wins tenders: documented service delivery, clean financial management, and people processes that survive an interview with frontline staff, not just a policy document.

Standard ACS versus Pacesetters

This distinction matters directly at tender stage. Pulse Operations's guide, How to win your next security tender, notes that most formal tenders — especially public sector — are decided on a published price/quality split commonly between 60/40 and 30/70, and that on a 40/60 split, a bid priced 5% higher but scoring one grade better on quality wins comfortably. ACS Pacesetters status is exactly the kind of verifiable evidence that lifts a quality score rather than a generic claim of "excellence."

Is ACS approval mandatory, and what happens after you get it?

SIA Approved Contractor status is not a legal requirement — a security company can trade lawfully without it, provided every deployed individual holds a valid SIA licence. What ACS approval changes is commercial access: many public-sector frameworks, shopping centre managing agents and large corporate occupiers in London specify ACS as a pre-qualification gate, and approved contractors gain a practical operational advantage too.

Approved contractors may deploy up to 15% of their workforce under a licence dispensation notice while individual licence applications are being processed — an option unavailable to non-approved firms, according to SSAIB (2026). For a firm scaling quickly to cover a new contract, that flexibility can be the difference between meeting a mobilisation deadline and breaching it.

Approval is not permanent. After the initial assessment, approved contractors are reassessed annually, and where an assessor identifies improvement needs, they must be addressed within the timeframe the assessor sets — a requirement Pulse Operations details in The ACS self-assessment: how to evidence it. A firm that lets its evidence lapse between visits risks losing approval at the next reassessment, which is why treating compliance as a continuous operational habit — not an annual scramble — matters more than the initial application.

Trading falsely as "SIA approved" without holding current ACS status is a serious matter; buyers checking a contractor's claim can and do verify status directly against the SIA's published list of approved contractors on GOV.UK.

Your SIA approved contractor status checklist

• Confirm eligibility: at least one full year of trading accounts and a clean financial standing check
• Work through the ACS Self-Assessment Workbook against all 78 indicators before submitting anything
• Centralise staff files, BS 7858 screening records, licence numbers and training certificates in one system, not scattered spreadsheets
• Choose a UKAS-accredited assessing body such as SSAIB or NSI and confirm their fee and timeline
• Reconcile rosters against actual payroll hours before the verification visit, not during it
• Brief frontline staff so they can describe policies accurately if an assessor interviews them
• Budget for the per-licensable-individual fee rising to £25 from 1 June 2026 in renewal and tender pricing
• Set a recurring internal review ahead of each annual reassessment, not a scramble the week before

FAQ

What is SIA Approved Contractor Scheme (ACS) status?

SIA Approved Contractor Scheme status is a voluntary company-level accreditation from the Security Industry Authority that certifies a security business meets a national operational standard across seven criteria and 78 indicators. It sits above individual SIA licensing, which certifies individual officers rather than the company itself.

How much does it cost to become an SIA approved contractor?

Application fees range from £400 to £2,400 depending on company size, according to Coredinate (2026), plus a separate assessor fee and an annual per-licensable-individual registration fee rising from £15 to £25 from 1 June 2026, per Security Matters Magazine (2026).

What is the difference between an SIA licence and ACS approval?

An SIA licence is issued to a named individual after background checks and mandatory training, while ACS approval is issued to a company and assesses the whole business against seven criteria including strategy, service delivery, financial management and people.

What are the eligibility requirements for SIA ACS approval?

Eligibility generally requires at least one full year of trading accounts, a clean financial standing check, and evidence the business supplies licensable security services under the Private Security Industry Act 2001. There is no minimum company size, so sole traders and large national providers are assessed against the same standard.

How long does it take to get ACS approved?

Timescales vary by assessing body and how prepared the applicant's evidence is, but firms that complete the ACS Self-Assessment Workbook thoroughly before applying and centralise their staff, training and screening records tend to move through verification faster than those assembling evidence reactively.

What is the Standard Route versus the Passport Route for ACS approval?

The Standard Route requires a full self-assessment and on-site verification visit and is the default path for most applicants. The Passport Route is a faster option for firms that already hold an equivalent, SIA-recognised quality certification, letting them carry some existing evidence across rather than rebuilding it from scratch, per the National Business Crime Centre guidance.

How often do you need to renew ACS approval?

Approved contractors are reassessed annually after their initial assessment, and any improvement needs identified by the assessor must be addressed within the timeframe the assessor sets, according to Pulse Operations's guide, The ACS self-assessment: how to evidence it.

What is ACS Pacesetters status and how is it different from ACS approval?

ACS Pacesetters status is awarded only to the top 15% of companies within the ACS scheme, based on self-assessment workbook score, according to ACS Pacesetters (2026). With roughly 700 companies ACS-approved as of July 2026, only around 105 fall into the Pacesetters band, per ProFM Group (2026).

Proving the evidence behind SIA approved contractor status with Pulse Operations

Every stage of the ACS journey described above depends on the same underlying problem: evidence that matches reality, produced on demand rather than reconstructed under deadline. That's the exact gap Pulse Operations was built to close, because photo-verified patrols, tamper-evident occurrence logs and a live compliance runway generate the People and Service delivery evidence an assessor asks for as a by-product of daily operations, not a separate annual project.

At Priority First, the founding team's own London security & FM operation, checkpoints across a 152-point West London mixed-use site are completed by a mandatory watermarked photograph — officer, site, GPS, time — with no tag scans, producing a dated, attributable record of exactly what was checked and when. That's the same standard of proof ACS assessors expect when they cross-check rosters, training records and site documentation against what actually happened on the ground.

If you're preparing an ACS application, gearing up for a reassessment, or bidding a tender that gates on ACS status, Pulse Operations's compliance runway is worth a look — get in touch for a tour of how it tracks SIA licences, BS 7858 screening and training expiries in one place, no deck required.
