The verdict in three sentences
A London security guarding company wins contracts with banks, property managers and logistics sites on proof of compliance and operational capacity, two things most sector websites barely show. The useful site combines a quote form by site type, a visible SIA licensing and ACS status page and a recruitment module able to absorb 300 applications a month, for a 2026 market budget of 15,000 to 28,000 GBP. Delivered in about 6 weeks, it becomes both a sales tool and a hiring tool.
What buyers of private security look for in London
The facilities director of a bank in the City, or the operations manager of a distribution centre in Park Royal, does not pick a guarding contractor from a brochure. Before calling, they check three things: that every officer holds a valid SIA licence, whether the company is an SIA Approved Contractor (ACS), and whether it can staff several sites at once with vetted officers. A company with 1,200 officers covering bank branches, warehouses and embassy residences must show these points within 30 seconds.
An effective site is organised by need: financial services, commercial property and offices, retail and shopping centres, logistics and industrial, residential and diplomatic, events, mobile patrols and alarm response. Each page details services, supervision ratios (often 1 supervisor per 8 to 12 officers), equipment provided and anonymised or client-approved references.
| Component | 2026 market range | Commercial role |
|---|---|---|
| Corporate site, 15 to 20 pages | 15,000 to 28,000 GBP | Credibility with key accounts |
| Quote form by site type | 1,800 to 3,500 GBP | Qualified B2B leads |
| SIA, ACS and insurance page | 600 to 1,200 GBP | Removes compliance objections |
| Recruitment module (300 applications a month) | 3,000 to 6,000 GBP | Automatically screened hiring flow |
| Client portal (patrol reports) | 6,000 to 12,000 GBP | Contract retention |
| Typical market maintenance | 250 to 600 GBP a month | Updates and backups |
| Delivery time | 6 weeks | Ready before a tender deadline |
The quote form that actually qualifies
Most security firms publish a plain contact form. The result: vague requests, wasted callbacks and quotes built blind. A 4-step form changes this. The buyer picks the site type, states the size or number of access points, sets hours (day, night, 24/7) and the number of posts. The system estimates full-time equivalents: a permanent 24/7 post in practice needs 4.2 to 5 officers once rest days and holidays are counted.
| Form question | Why it matters | Effect on the quote |
|---|---|---|
| Site type | Bank, office, warehouse | Officer skill level |
| Number of posts | 1 to 50 | Base for the FTE calculation |
| Hours | Day, night or 24/7 | Factor of 1 to 5 officers per post |
| Licence type | Door supervision, CCTV, guarding | Training and pay rate |
| Equipment | Electronic patrol tags, CCTV | Separate equipment line |
| Start date | Urgent or planned | Mobilisation capacity |
| Location | Central London, M25 belt | Travel and cover cost |
This level of detail lets the sales team call back with a priced proposal within 24 hours instead of 5 days. Each request lands pre-sorted by segment in the CRM.
Officer recruitment: a flow to industrialise
A guarding company of 1,200 officers often sees annual turnover of 25 to 40 %. That means hiring 300 to 480 officers a year, and the site easily receives 300 applications a month. Without screening, CVs arrive by email, job boards and walk-ins, and HR loses whole days to them.
The recruitment module asks knock-out questions (valid SIA licence number, right to work in the UK, 5-year employment history for BS 7858 vetting, night availability), accepts uploads from a phone, and sorts candidates by home borough to reduce lateness and no-shows. It can also check the licence number against the public SIA register before a recruiter even opens the file.
At Kolonell, a Premium showcase site sits between 3,050 and 5,340 EUR, while specific modules (multi-step quote, applicant screening, client portal) are priced in the quote. If the client area becomes a full portal with patrol reports and incident logs, it is a custom web application, starting at 3,810 EUR for a simple app. Kolonell maintenance is available at 53, 114 or 183 EUR a month depending on the service level.

Mini case study
David, managing director of a London guarding company (1,200 officers), handles 20 quote requests a month and converts 4. After launching a qualifying form, he receives 28 and his win rate moves from 20 to 25 %, so 7 contracts a month instead of 4. With an average contract of 6 posts at about 3,900 GBP per officer per month, each extra contract adds roughly 23,400 GBP of monthly revenue. Three more contracts mean about 70,000 GBP a month. On the HR side, automated screening saves 3 hours a day for two recruiters, about 130 hours a month. A 24,000 GBP investment is covered within the first month of billing the new contracts.
FAQ
How much does a security company website cost in London in 2026?
As a 2026 order of magnitude, a full corporate site with quotes and recruitment costs 15,000 to 28,000 GBP on the market. A client portal with patrol reports adds 6,000 to 12,000 GBP.
Should we show SIA and ACS status on the site?
Yes, it is the first check made by banks and property managers. Show your ACS status, insurer and the licensing process for officers on a dedicated page one click from the homepage.
How do we handle 300 applications a month without swamping HR?
With 5 to 7 knock-out questions and automatic sorting by borough and availability. In practice, 60 to 70 % of non-compliant applications are filtered before any human reads them.
Can the form check SIA licences automatically?
It can pre-check the licence number format and link to the public register, which cuts screening time by about 5 minutes per candidate. Final verification stays with your vetting team under BS 7858.
What timeline should we plan?
About 6 weeks: 1 week of scoping, 3 weeks of design and build, 2 weeks of form testing and launch.
