In short

Supporting security companies at every stage.

Security companies usually need finance because officers are paid weekly or fortnightly while clients, often facilities management contractors, typically pay 30 to 60 days later.

Invoice finance is the standard answer and grows with each contract won; working capital loans fund mobilisation and staff transfers; asset finance covers patrol vehicles and monitoring equipment. Lenders focus on contract terms, client concentration and SIA licensing across the workforce.

Can a security company fund the cost of SIA Approved Contractor status?

Yes, and many contracts make it worth funding. Becoming an SIA Approved Contractor means an application fee paid to the SIA, an annual registration fee for every licensable person deployed, an assessment by a certification body, and often new policies, training and management software before the assessor arrives. A small unsecured loan or a working capital facility can spread those costs, and because approved status opens tenders that ask for it, lenders tend to view the spend as an investment in contract income rather than an overhead. The SIA application fee runs from £400 for up to 10 licensable staff to £2,400 for more than 250, and the annual registration fee rose from £15 to £25 per licensable individual deployed on 1 June 2026, so a company deploying 120 officers pays £3,000 a year in registration fees alone. We arrange funding for security companies preparing for approval and can size it to cover the first year's fees and the assessment together.

Is the SIA Approved Contractor Scheme compulsory?

No. The Approved Contractor Scheme is voluntary, unlike individual licensing, but it carries real commercial weight. Many public sector buyers, facilities management contractors and larger corporate clients ask for ACS status in their tenders, and approved contractors appear on a public register that buyers check. Approval is assessed against an SIA standard by an independent certification body, and the company must keep meeting it at annual assessments to stay on the register. The SIA has said it intends to launch a new business approval scheme during its 2026 to 2027 business year, so check the current position before budgeting for renewal.

  • Fee scale

    The application fee depends on how many licensable staff the company has, so a growing firm pays more at its next renewal.
  • Annual cost

    The registration fee is paid every year for as long as the company remains approved, and belongs in the cash flow forecast.
  • Tender access

    Lenders give more weight to contracts won through frameworks that require ACS, because those clients tend to pay reliably.
  • Assessment costs

    The certification body charges for its assessment separately from the SIA fees.

The SIA sets out the process and fees in apply for ACS approval. Our unsecured business loans page covers borrowing without property, working capital loans explains funding growth costs, and Growth Guarantee Scheme loans covers the government backed route. Instant Quotes lines up panel lenders for the approval costs in a few minutes.

Finance options for security companies

01

Invoice finance

Invoice finance pays you the bulk of a monthly invoice on the day you issue it, so payroll for a new contract is funded by the contract itself. Funders will want invoices backed by client-approved hours or timesheets, and they assess the credit of the clients more than the security company. A facilities management contractor or public body makes a strong debtor; a nightclub makes a weaker one. Where most income sits with one or two clients, selective invoice finance can fund particular contracts rather than the whole ledger.

02

Working capital loans

Working capital loans fund mobilisation costs that come before any invoice exists, such as uniforms, equipment, recruitment and training for a large new site. Term them to the contract length, not the first year.

03

Revolving credit

A revolving credit facility covers the seasonal swing of event work and the weeks after a TUPE transfer.

04

Asset finance for vehicles and equipment

Patrol and response vehicles suit vehicle and fleet finance. Alarm receiving centres, monitoring software and the CCTV systems you install for clients can be funded through CCTV and security system finance.

05

Acquisition finance

Buying a competitor adds contracts and licensed staff. Check whether client contracts can be ended on a change of ownership, and whether the target's officers are correctly employed. Acquisition finance explains how lenders assess the purchase.

Can I get a loan to start a security company?

Yes, though lenders fund the first contracts more readily than the idea. A new guarding or key holding company can borrow modestly from day one through a personal Start Up Loan or a small unsecured loan backed by the directors, and asset finance can cover a patrol vehicle, radios and body worn cameras. The bigger money arrives once the first contract is signed, because invoice finance advances against each monthly invoice and lets the company pay officers weekly while the client pays on 30 to 60 day terms. Lenders look at the signed contract or letter of intent, the directors' experience in the industry, the SIA licences held by the directors and officers, insurance cover and a cash flow forecast that shows payroll being met. We look for lenders that work with new security businesses and line the facility up so it is ready before the first shift starts.

Do I need an SIA licence to run a security company?

Yes, if the company supplies licensable security staff under contract. The Private Security Industry Act 2001 makes it an offence to supply unlicensed operatives, and directors of a company whose directors, partners or employees carry out licensable work must hold an SIA licence themselves. A director who will not work on the front line applies for a non front line licence, and one that already holds a front line licence for guarding or door supervision does not need a second. The rule reaches shadow directors and the directors of a parent company whose subsidiary deploys licensed staff. SIA licensing applies across the UK, and every officer the company deploys must hold the right licence for the activity on the contract.

  • Contract first. Lenders size invoice finance on the value of signed contracts, so winning the first site matters more than the business plan.
  • Director checks. Lenders and the SIA both look at the directors' history, so an unsettled county court judgment or a past insolvency should be explained at the start.
  • Insurance. Public liability, employers' liability and professional indemnity cover is usually asked for before any facility goes live.
  • Payroll timing. Weekly wages against monthly invoices are the main reason a new security company needs funding at all.

The SIA explains licensing requirements for directors. Our start up business loans page covers new companies, invoice factoring explains funding payroll against contract invoices, and asset finance covers vehicles and equipment. Instant Quotes shows which panel lenders would look at a new security company, using a soft search that leaves your credit file untouched.

Where the money goes in a security business

Guarding is a labour business with thin margins. Wages and the costs that follow them make up most of the price a client pays, so small timing differences create large cash demands.

  • Payroll before payment. Officers are paid weekly or fortnightly. Clients pay monthly invoices on 30, 45 or 60-day terms, and large facilities management contractors may pay later still.
  • Mobilising a contract. Winning a new site means screening and vetting officers, uniforms, radios, body-worn cameras, site-specific training and sometimes a supervisor's vehicle, all before the first invoice.
  • Staff transfers. When a contract changes hands, officers often transfer to the new provider under TUPE, bringing accrued holiday and existing pay rates with them.
  • April cost rises. Increases in the National Living Wage and employer National Insurance hit immediately. Contracts without a price review clause leave the provider absorbing the difference.
  • Event peaks. Festivals, sport and summer events need large casual teams for short periods, with payment from organisers after the event.

Illustration: mobilising a guarding contract

Illustration. A hypothetical firm wins a two-year contract to guard a distribution site, needing twelve officers. Before the first invoice it spends around £15,000 on vetting, uniforms, radios and site training, and pays two fortnightly payrolls of roughly £25,000 each. The client is invoiced monthly and pays on 45-day terms, so the first payment arrives about two and a half months after the start. A small working capital loan covers the £15,000 set-up cost over the contract term. An invoice finance facility then advances most of each monthly invoice as it is raised, so later payrolls are funded from the contract's own billing. Before signing, the firm checks that the hourly rate still leaves a margin after holiday pay, sickness cover and the April wage rise.

Risks and trade-offs

  • Winning the wrong contract. A large contract priced too low can consume cash faster than any facility can supply it. Model the margin after holiday pay, sickness cover and supervision before bidding.
  • Invoice finance commitments. Check minimum terms, notice periods and fees for leaving, and whether the facility covers every client or only some.
  • Bad debts. Hospitality and event clients fail more often; ask whether credit protection is available or needed.
  • Personal guarantees are usual, including warranties on invoice finance.
  • Alternatives. Negotiating a mobilisation payment, shorter payment terms or a price review clause with the client can do more than borrowing. For tax, compare a loan with HMRC Time to Pay; see Time to Pay versus a tax loan.
Underwriting

What lenders look at in a security firm

01

Clients and contracts

Who the clients are, contract length, notice and break clauses, price review terms and payment terms.

02

Concentration

The share of income from the largest client.

03

Licensing

Front-line staff in licensable roles need an SIA licence; see find out if you need an SIA licence. Membership of the SIA Approved Contractor Scheme is voluntary, but many buyers require it and lenders treat it as evidence of sound management.

04

Employment status

Lenders are wary of firms that deploy officers as self-employed or through layers of subcontractors. HMRC has published guidance on how its rules apply to the security operatives you deploy, and unpaid tax and National Insurance on misclassified workers can fall on the business.

05

Margins by contract

, holiday pay accrual and overtime levels.

06

Insurance

, including employer's and public liability cover suited to the work.

FAQs

Questions clients ask

Can we fund payroll for a new contract before the first invoice?

Invoice finance cannot advance on an invoice that does not exist yet, so the first weeks of a new contract are usually carried by a short loan or an overdraft-style facility. Once invoicing starts, invoice finance can take over.

Does invoice finance work with clients who self-bill or pay through portals?

Usually, yes. Many facilities management contractors self-bill or require invoices through a portal. Funders will want to see the approval process and how often hours are disputed or adjusted.

Can a new security company get invoice finance?

Yes, often once it has signed contracts with creditworthy clients, because the funder relies mainly on those clients paying. Limits tend to start small and grow with turnover.

Can we finance SIA training and licence fees for new officers?

These are usually covered within a working capital loan rather than financed separately. Some firms recover the cost through training agreements with officers; make sure any repayment terms comply with minimum wage rules.

Can security company finance cover a VAT bill?

Yes, VAT and corporation tax bills can often be spread over monthly payments with a short-term tax loan, which helps a guarding business whose cash is tied up in unpaid invoices when a quarter falls due. Lenders look at turnover, the quality of your clients and how the bill arose, and directors are usually asked for a personal guarantee. If you already use invoice finance, check that its terms allow other borrowing first. Our page on VAT loans explains how these work.

Can I get instant quotes for security company finance?

Instant Quotes shows which lenders on our panel are likely to fit your business, with no credit search. Invoice finance is then sized after the funder reviews your contracts and debtor book.

Can I get a loan to start a security company?

Yes. A new security company can start with a personal Start Up Loan, a small unsecured loan or asset finance for vehicles and equipment, and invoice finance follows once the first contract is signed. Lenders look at the contract, the directors' experience, SIA licences, insurance and a payroll forecast. Smart Funding Solutions is a whole of market broker that sources lenders for security businesses.

Do I need an SIA licence to run a security company?

Yes, if the company supplies licensable staff under contract. Directors of such a company must hold an SIA licence, using a non front line licence if they do not work on the front line, unless they already hold a front line licence. The rule covers shadow directors and parent company directors. SIA licensing applies across the UK.

Can a security company fund the cost of SIA Approved Contractor status?

Yes. An unsecured loan or working capital facility can spread the SIA application fee, the annual registration fee and the certification body's assessment. The application fee runs from £400 for up to 10 licensable staff to £2,400 for more than 250, and the registration fee rose to £25 per licensable individual deployed on 1 June 2026. Smart Funding Solutions arranges finance for security companies.

Is the SIA Approved Contractor Scheme compulsory?

No. The SIA Approved Contractor Scheme is voluntary, but many public sector buyers and facilities management contractors require it in tenders. Approval is assessed by an independent certification body against an SIA standard, and the company must pass annual assessments and pay an annual registration fee for each licensable individual deployed to remain approved.
