SME loans are business finance for companies with fewer than 250 employees. The right product depends on what the money is for…
How security firms fund weekly payroll against slow-paying clients, mobilise new contracts and finance patrol vehicles, and what lenders check first.
“The whole process was very smooth and was completed within a few days.”
In short
Supporting security companies at every stage.
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.
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.
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.
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.

Smart Funding Solutions is a broker, not a lender: we search lenders across the whole market, including invoice finance providers used to labour-heavy contracts, and arrange facilities from £10,000 to £20 million. More sectors are listed on our SME loans hub.
Choose the need, and we’ll show you how lenders usually structure it.
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.
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.
A revolving credit facility covers the seasonal swing of event work and the weeks after a TUPE transfer.
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.
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.
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.
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.
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.
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.
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.

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.
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.

| Service | Typical billing | Lender view |
|---|---|---|
| Static guarding on long contracts | Monthly, from approved hours | Predictable; well suited to invoice finance |
| Mobile patrols and key-holding | Monthly fixed fee plus call-outs | Recurring and valued; vehicle-dependent |
| Door supervision | Weekly or monthly to pubs and clubs | Smaller, weaker debtors; more bad debt risk |
| Event security | Per event, often after it ends | Lumpy; depends on the organiser's finances |
| Remote CCTV monitoring | Monthly per site | Recurring, higher margin, equipment-heavy |
We start with your contracts, clients and payroll cycle, then decide with you whether the need is timing, mobilisation, equipment or an acquisition. Lenders on our panel that already fund labour-based contracts get a clear account of your sites and clients from us, and you get their offers compared on advance, cost, notice and guarantees. Lenders make the final decision. Any broker fee is disclosed separately before you proceed. Providers of event security may also find our page on events business finance useful, and staffing businesses supplying other sectors can see recruitment finance.

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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
