Imperial Security provides key holding for homes and businesses in Mortlake, giving shop owners on Mortlake High Street, office occupiers near Upper Richmond Road and residents around Mortlake Green a dedicated keyholder who can attend day or night.
Our guards respond to activated alarms, carry out lock and unlock visits and check on empty premises, so you are never the one who has to leave a warm bed to find out why a siren is going off.
Mortlake is changing. The former Stag Brewery site by Mortlake Green stood empty for close to a decade before the redevelopment finally secured approval for over 1,000 new homes and commercial space, and a project of that size means a long construction period with plant, materials and partly built units on site that need a reliable keyholder rather than an ad hoc arrangement. Alongside that, the High Street's mix of Edwardian buildings, older converted residences and small shopfronts means many premises still run on mechanical locks and older alarm panels rather than modern access control, so a keyholder who understands the building matters as much as one who understands the alarm.
Whether you run a shop on Mortlake High Street, manage a small office off Upper Richmond Road, or own a let property near the river, our key holding service gives you a single point of contact for out-of-hours issues. We hold your keys securely, respond to alarm activations, and keep you informed with a clear report after every callout.

| What Our Mortlake Key Holding Service Provides
From High Street shopfronts to riverside offices, these are the six duties our Mortlake keyholding clients rely on most.
Secure key storage
Your keys are held off site in a secure facility, released only to vetted guards attending your Mortlake property.
Emergency alarm response
When an alarm triggers at your High Street shop or Mortlake office, a guard is sent to investigate and re-secure the building.
Routine property checks
Scheduled visits look for signs of forced entry or water damage, useful for vacant flats and holiday lets near the river.
Lock and unlock visits
A guard opens or closes your Mortlake premises to a set schedule, useful for shops, small offices and school gates.
Incident reporting
Every callout is logged and reported to you promptly, so you know exactly what happened and what was done about it.
Liaison with emergency services
Where an incident needs the police or fire brigade, our guard liaises with them on site until the property is secure again.
| Who We Provide Key Holding For In Mortlake
Our Mortlake key holding clients tend to fall into four groups.
High Street shop owners
Independent shops along Mortlake High Street need a keyholder who can respond fast to an alarm outside trading hours.
Small offices off Upper Richmond Road
Office occupiers who lock up before the last person leaves need a keyholder for out-of-hours alarm callouts.
Landlords and Airbnb hosts
Owners of let flats and holiday properties near the river need checks between guests and a keyholder for empty periods.
Schools and small businesses
Sites that open and close on a fixed timetable use our lock and unlock service to remove the burden from staff.
We also support developers and contractors managing partly built or vacant sites in Mortlake, including work connected to the wider Stag Brewery redevelopment.
| The Security Problems We Solve In Mortlake
Mortlake's mix of older buildings, riverside properties and a long-term construction site nearby creates specific problems that a standard alarm contract does not solve on its own.
Nobody available to attend an alarm
Shop and office staff often live some distance from Mortlake, so an alarm at 2am can go unattended for hours. Our guard attends in your place, every time.
Older locks and alarm panels
Many buildings along the High Street predate modern access control. We keep detailed notes on each property's locks and panel so our guards know exactly what they are dealing with on arrival.
Empty properties near the river
Flats and holiday lets close to the Thames can sit empty between tenancies or bookings. Scheduled checks catch leaks, forced entry or storm damage before they become a bigger repair bill.
Construction and vacant land near Mortlake Green
Long-running development sites attract attention once fencing and plant appear. We hold keys and gate codes for site cabins and compounds and respond if an alarm or intrusion is reported.
