The verdict in three sentences
For a manned guarding company in London, the website is not decoration: it is the first compliance filter a facilities manager, bank or embassy applies before inviting you to tender. A budget of 6,000 to 25,000 EUR is enough for a credible site, provided it publishes SIA licensing, ACS status, officer training and a structured tender form. One monthly contract of 15,000 EUR won through the site usually pays for the whole project within a quarter.
What a corporate buyer checks before contacting you
Procurement teams at banks, data centres, logistics hubs and embassies work from approved supplier lists. The security manager or buyer visits your site to tick boxes, often before any phone call. If the information is missing, they move to the next supplier.
| Buyer requirement | What the site must show | Impact on shortlisting |
|---|---|---|
| SIA licensing for all officers | Statement of 100 % licensed staff, licence checks process | Disqualifying if absent |
| SIA Approved Contractor Scheme | ACS status and renewal date | Often a hard tender criterion |
| Headcount and coverage | 400 officers, Greater London, Home Counties | Proves capacity for large sites |
| Officer training | Induction, refresher training, first aid, counter-terrorism awareness | Scored in bank and FM tenders |
| Supervision | 24/7 control room, mobile patrols, supervisor ratios | Reassures embassies |
| Sector references | Sectors served (finance, logistics, retail, residential) | Speeds up invitations |
| Insurance and compliance | Public liability cover level, London Living Wage stance, BS 7858 vetting | ESG criterion for corporates |
The key point: corporate buyers also look for ISO 9001 and BS 7858 screening. Put them on the homepage, not buried in a PDF.
What the site costs in 2026: options compared
Figures below are 2026 market estimates for the London area, excluding VAT.
| Option | Budget | Timeline | Limits |
|---|---|---|---|
| Directory listings only | 0 to 500 EUR | 1 day | No credibility with a bank buyer |
| Freelancer, WordPress theme | 2,500 to 6,000 EUR | 3 to 5 weeks | No tender form, uncertain maintenance |
| Small London agency | 8,000 to 18,000 EUR | 6 to 10 weeks | Quality varies widely |
| Mid-size London agency | 20,000 to 45,000 EUR | 10 to 16 weeks | Strong but costly |
| French-speaking nearshore agency (Kolonell Growth) | 1,830 to 3,050 EUR | 3 to 4 weeks | Remote collaboration, English copy reviewed by you |
| Kolonell Premium | 3,050 to 5,340 EUR | 4 to 6 weeks | Advanced SEO, document library, animations |
For a 400-officer firm targeting corporates, a bilingual or multi-sector Growth build is the most coherent choice. Monthly maintenance keeps licences, ACS certificates and insurance documents current, which buyers do check.
The pages that generate quote requests
An effective security website fits into 8 to 12 well-structured pages:
- Home with key figures (officers, sites guarded, years trading) and a "Request a quote" button.
- One page per sector: corporate offices, banks, logistics and warehouses, embassies and residences, construction, events.
- Accreditations and compliance with downloadable certificates.
- Training and careers, which also supports recruitment in a tight labour market.
- Tender form: site type, number of posts, hours, dog units, mobile patrols, start date.
- Contact with control room number and office address.
The structured form changes everything: it qualifies the request and lets you price a quote within 24 hours instead of three phone calls.

Mini case study
James, sales director of a London guarding firm (illustrative scenario), invests 15,000 EUR in a multi-sector site and 300 EUR a month in maintenance, about 18,600 EUR in year one. The form generates 6 qualified requests a month. With a cautious 10 % conversion rate, he signs about 7 contracts a year. At an average contract of 20,000 EUR a month and an 8 % net margin, each contract brings 1,600 EUR of monthly margin. A single contract therefore covers the annual site cost in under 12 months, and seven contracts add roughly 11,200 EUR of margin every month.
FAQ
How much does a manned guarding website cost in London in 2026?
Expect 8,000 to 18,000 EUR with a small London agency, as a 2026 estimate. A nearshore French-speaking agency such as Kolonell quotes 1,830 to 3,050 EUR for a Growth build.
Should we publish our ACS status on the site?
Yes, it is the first check for many corporate buyers. Show the status, renewal date and a link to the SIA register, and update it at each renewal.
Do we need a separate careers section?
Yes, if you recruit more than 50 officers a year. Agency fees often reach 15 to 20 % of a first-year salary, so a careers page with an online form pays back quickly.
How fast can the site go live?
Between 3 and 6 weeks depending on scope. The bottleneck is usually gathering documents: ACS certificate, insurance schedule, officer photos.
How do we measure ROI?
Track quote requests from the tender form and your win rate. With contracts worth 15,000 to 60,000 EUR a month, one signature usually pays for the project.
