Imperial Security provides key holding and alarm response for offices, shops and residential blocks across Hammersmith, from the Broadway and King Street shopping streets to the office buildings around the one-way system and the quieter terraces off Brook Green and Glenthorne Road.
Our SIA-licensed guards hold your keys securely off site and attend in person whenever your alarm activates, day or night, so a director, a facilities manager or a landlord never has to leave home to check a false trigger or a genuine break-in. We handle the call-out, check the building inside and out, and report back with a clear record of what happened.
Hammersmith runs on a mix of large commercial floorplates and smaller independent premises, and that mix shapes who actually needs a key holder. Hammersmith BID, which funds public realm and safety work across the town centre for its current 2026 to 2031 term, works alongside businesses on the Broadway and King Street, but a BID cannot answer your alarm at 2am. Ongoing works around the Civic Campus and King Street, including pavement and cycle lane changes near the Town Hall, mean access routes and out-of-hours deliveries in that stretch can change at short notice, which is exactly the kind of local detail a control room needs to know before dispatching a guard.
Responding to your own alarm is disruptive and, late at night, can put you in a genuinely risky position with no way of knowing what you are walking into. Imperial Security removes that risk. Our guards attend as trained first responders, assess the property calmly and take the right action, whether that means resetting a faulty sensor or securing a breach and calling the police. You get a full incident report once the situation is closed, so nothing is left unexplained.

| What Our Hammersmith Key Holding Service Provides
From Broadway offices to the smaller shops and flats around King Street and Brook Green, these six duties cover the day-to-day realities of holding keys for a Hammersmith property.
Rapid alarm response
When your alarm activates, our control room dispatches a Hammersmith-based guard who carries out a full external and internal check of the property to establish the cause and confirm the building is secure.
Secure key management
Your keys are stored off site in a monitored safe to British Standard BS 7984, with every access logged so there is always a clear, auditable record of who held them and when.
Incident management and reporting
If a guard finds signs of a break-in, they secure the property, liaise directly with police and give you a written incident report once the situation is resolved, so you know exactly what happened before you arrive.
Controlled access for contractors
We can let in cleaners, engineers or tradespeople outside normal hours, checking identity against your instructions so you never need to attend site yourself for a routine visit.
Out-of-hours building checks
Beyond alarm call-outs, we can carry out scheduled checks on empty offices or vacant units, particularly useful for the buildings currently affected by works around the Civic Campus and King Street.
Emergency callout coordination
Where a burst pipe, power fault or similar emergency needs a locksmith, plumber or engineer, we can grant access and stay on site until the contractor has finished and the property is secure again.
| Who We Provide Key Holding For In Hammersmith
Our key holding clients in Hammersmith reflect the area's mix of commercial, retail and residential property.
Office occupiers
Hammersmith's office buildings around the Broadway and along the one-way system need a key holder who can respond to alarms and let in cleaning or maintenance contractors without a manager having to travel in.
Retailers on King Street and the Broadway
Shops along King Street and inside the Broadway centre need someone who can attend an after-hours alarm quickly, especially while nearby pavement and access works are under way.
Residential blocks and managing agents
Managing agents for flats near Brook Green and Hammersmith Grove rely on us to hold communal keys and respond to alarms so residents are not left waiting on a director or agent to arrive.
Landlords with vacant units
Landlords with units standing empty during refurbishment or between tenants need a key holder who can grant access to surveyors and contractors and check the property is secure between visits.
We also hold keys for restaurants and cafes around the Broadway and Hammersmith Grove, and for community and leisure premises across the area.
| The Security Problems We Solve In Hammersmith
Hammersmith's town centre is in a period of change, and that creates practical problems that a key holding service is well placed to solve.
Nobody available to answer an out-of-hours alarm
Small business owners and busy managers are rarely in a position to drop everything and drive to Hammersmith at 3am. We take that call instead and attend in person, so the alarm is dealt with whether or not you are reachable.
Works around King Street and the Civic Campus changing access
With pavement and cycle lane changes under way near the Town Hall, normal routes and parking near affected premises can shift week to week. Our local guards keep track of these changes so response is not delayed by a diversion they did not expect.
Vacant units left unchecked
An empty shop or office between tenants is easy to overlook, and a fault or forced entry can go unnoticed for days. We can schedule regular checks so problems are caught early rather than discovered on the next viewing.
Uncontrolled key copies and handovers
Passing keys between staff, contractors and agents with no record makes it hard to know who can get into a property. Our BS 7984 storage and logged handovers give you a single, accountable point of control.
