In short

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.

This page is for owners of manned guarding, mobile patrol, key-holding, door supervision, event security and remote monitoring businesses. Smart Funding Solutions is a broker, not a lender: we search our panel of 300+ lenders, including invoice finance providers used to labour-heavy contracts, and arrange facilities from around £10,000 to £500,000+, with larger facilities available in suitable cases. More sectors are listed on our SME loans hub.

Finance options for security companies

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.

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.

Revolving credit

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

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.

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.

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

Clients and contracts

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

Concentration

The share of income from the largest client.

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.

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.

Margins by contract

, holiday pay accrual and overtime levels.

Insurance

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

Service lines and how lenders see them

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

The broker’s view

How we help security businesses

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. It is free to enquire; 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.

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.
