Plan manned guarding, key holding and alarm response for your London premises. USSG reviews your building, required hours and access arrangements before agreeing the duties, staffing and start date.
SIA Approved Contractor: Security Guarding & Key Holding · 24/7 support
Choose the cover your premises need
A reception desk, a shared building and an unattended property each need a different brief. Decide whether the priority is an officer on site, an alarm-response arrangement or guarding for a defined project period.
Key holding & alarm response
Agree how keys, alarm activations and authorised access will be handled. Identify who can approve attendance, provide access instructions and receive the report.
View key holding and alarm response
Project & vacant property guarding
Discuss cover during refurbishment, a change of occupier or a period when premises are empty. Confirm contractor access, restricted areas and the duties required while work is underway.

Separate tenant duties from building-wide security
If your London office sits within a larger managed building, your security brief needs to fit the existing arrangements. Confirm what the landlord or building team already handles before commissioning additional cover.
| Part of the assignment | Question to resolve | What to record |
|---|---|---|
| Reception and shared entrances | Does your assignment cover the whole building or only your premises? | The entry points and areas included, with the responsible building contact. |
| Visitors and access permissions | Who can approve a visitor or issue permission for restricted areas? | Authorised contacts and the agreed sign-in or access-check procedure. |
| Contractors outside normal hours | Who confirms a booking and allows entry after staff leave? | The approval route, access window and any escort requirement. |
| Alarms and keys | Which alarms and doors belong to your premises rather than shared areas? | The key handover, relevant alarm contacts and attendance instructions. |
| Reports and escalation | Who should receive routine reports and urgent concerns? | Named recipients, escalation contacts and the required reporting format. |
Do not buy two services to cover the same undefined duty
Review any existing building security before requesting additional manned guarding. For unattended periods, compare the need for an officer on site with an agreed key holding and alarm-response service. Set clear boundaries between providers and contacts.
London service enquiries
Tell us the building, postcode and entrance
Contact USSG about a site in central London or another part of Greater London. Include the full address and postcode, rather than a borough name alone, so the team can assess the actual requirement.
- Central London enquiries
- Greater London enquiries
- Individual site assessment
If reception, service access and vehicle access are in different places, identify each one. For a property managed by a landlord or managing agent, explain who can authorise entry and approve the security instructions.
For several London premises, send a separate brief for each address. Shared reporting can be discussed, while duties and availability are confirmed site by site.

Discuss duties, building access and escalation contacts. A site assessment is arranged where appropriate to clarify the requirement.
- Step 03
Agree scope and price
Confirm officer numbers, shifts, attendance terms, reporting and applicable charges, with a proposed start date subject to availability.

Quote against a clear brief
What determines the cost of London security?
The assignment drives the price: officer numbers, hours, duties, site requirements and contract duration. State any reception, patrol or access responsibilities that must be included so the quote reflects the work.
For key holding and alarm response, clarify holding fees, call-out charges and additional attendance. For several properties, ask for the scope and charges for each site so differences remain visible.

London security questions
Answers about managed buildings, multiple properties, access duties and availability.
What security services can I request in London?
You can enquire about manned guarding, key holding and alarm response for London premises. Guarding duties may include reception security, visitor checks, patrols and cover for vacant or project sites. USSG confirms scope and availability after reviewing the requirement.
Can USSG work alongside existing building security?
Yes, you can discuss additional cover alongside existing arrangements. Explain which duties belong to the landlord, managing agent or current provider. The assignment should identify the areas covered, approval contacts and escalation route so responsibilities are clear.
Can I request cover for more than one London property?
You can submit a multi-site enquiry. Provide a separate address, hours and duty brief for each property. Reporting arrangements can be discussed across the requirement, while staffing, access instructions, charges and availability are confirmed for each site.
Does key holding replace a guard at the building?
Not automatically. Key holding and alarm response provide an agreed arrangement for keys and alarm activations. A guard remaining at reception or patrolling throughout a shift is a separate on-site requirement. Specify which duties you need before choosing the service.
Can you arrange out-of-hours contractor access?
You can request this as part of the proposed assignment. Identify who authorises the contractor, the approved entry window and any restrictions or escort requirements. The duties and any additional attendance charges must be agreed before the work is included.
Are security officers licensed and screened?
USSG security assignments use directly employed, SIA-licensed officers screened to BS 7858 before deployment. The company holds SIA Approved Contractor Scheme approval for Security Guarding and Key Holding. Current supporting information is available on the memberships and accreditations page.
How quickly can a London assignment start?
The start date depends on suitable staffing, the agreed duties and readiness of the site arrangements. Send the required date and hours when you enquire. USSG confirms the start date before booking; this page does not promise immediate deployment or a fixed arrival time.
How do I discuss a London security requirement?
Call 0330 341 2124 or use the contact page with the site postcode, required hours and duties. General office hours are Monday to Friday, 09:00–17:00. USSG provides 24/7 support; existing clients should follow the contact arrangements in their service plan.
