Imperial Security provides warehouse security guards for storage, distribution and light industrial sites in Mortlake, covering everything from single-unit stores to large multi-let warehouse space. We work with logistics operators, storage providers, contractors and site owners who need controlled access, regular patrols and a visible presence outside normal office hours.
Our SIA-licensed guards handle gatehouse duties, goods-in checks and out-of-hours cover, so a site manager who is not on site overnight still has someone accountable for the yard, the loading bays and the perimeter.
Mortlake's warehouse space is concentrated around the former Stag Brewery site on Mortlake High Street, where large sections of the old brewery buildings and yards are now let commercially for open storage and covered warehouse use, alongside smaller industrial units nearer the river and the A205. Planning permission for 1,075 new homes on the brewery site was approved on appeal in May 2025, so parts of that land are being used for storage and light industrial purposes in the interim while the wider scheme moves toward construction, which brings a mix of tenants, contractors and site traffic through shared access points that would not usually sit side by side.
That kind of transitional site, where storage tenants share yards and access roads with a live development, needs guards who can tell the difference between a scheduled delivery, a contractor vehicle and someone who should not be there. A warehouse on a quiet industrial road behind Mortlake High Street has different risks again, mainly around goods left in yards overnight and units that are only staffed during the day. Either way, the point of a guard on site is the same: someone checking who comes through the gate, walking the building regularly, and picking up the phone the moment something looks wrong.

| What Our Mortlake Warehouse Security Service Provides
Whether your unit sits within a larger multi-tenant site or stands alone off Mortlake High Street, these are the duties that keep goods, vehicles and staff safe day to day.
Entry and exit access control
Our guards check every vehicle and visitor against an approved list before they reach the yard, keeping a written log of who entered, when, and for what purpose, which matters most on shared sites with several tenants using the same gate.
Mobile patrols of the premises
Regular internal and external patrols cover the warehouse floor, external yards and fence lines, checking for forced entry, damaged locks, fire risks or anything left where it should not be.
CCTV monitoring and incident response
Where a site already has cameras installed, our guards can monitor live feeds through the shift and act on anything suspicious straight away, rather than reviewing footage after the event.
Alarm system support
Our guards work alongside whatever alarm system is already fitted, responding to activations promptly and liaising with emergency services if a genuine incident is confirmed.
Delivery and visitor supervision
Deliveries and contractor visits are checked in against expected schedules, with drivers directed to the right loading bay and their details recorded before they are allowed on site.
Out-of-hours lock-up and key control
For units that close before staff finish deliveries or open before anyone else arrives, our guards handle secure lock-up and opening so the building is never left unattended in between.
| Who We Provide Warehouse Security For In Mortlake
Our guards cover a range of storage and distribution operators across the area, including the following.
Storage and self-storage operators
Businesses letting out storage space in the area need a consistent presence to control who accesses individual units and shared corridors, particularly outside staffed hours.
Distribution and logistics tenants
Operators running goods in and out of the area need someone managing the gate and yard so drivers, pallets and stock movements do not go unchecked between shifts.
Light industrial and trade unit occupiers
Smaller trade and workshop units often close early or open late, leaving stock and equipment unattended for long stretches without a guard covering the site.
Site owners managing interim or transitional use
Landowners letting out warehouse or open storage space ahead of redevelopment need a guard who understands shared access arrangements and can keep tenants, contractors and the public apart.
We also cover construction site security and key holding for businesses in Mortlake that need cover beyond a single warehouse contract.
| The Security Problems We Solve In Mortlake
The redevelopment of the former Stag Brewery site has changed the pattern of activity around Mortlake High Street, with commercial storage tenants, contractors and eventually construction crews all sharing access points on the same stretch of road. That mix is exactly the kind of environment where enquiries tend to start, because it becomes harder to tell who has a legitimate reason to be on site.
Shared access points on multi-tenant sites
Where several storage or industrial tenants use the same gate, it is easy for an unfamiliar vehicle to slip through unchallenged. A guard on the gate checks every arrival against who is actually expected that day.
Goods left unattended in open yards
Open storage areas, including hard-standing yards used for pallets, vehicles and materials, are harder to secure than a locked building. Regular patrols and a visible guard presence reduce the window of opportunity for anyone testing the perimeter.
Units unattended outside working hours
Warehouses that operate set hours are most exposed overnight and at weekends, when a break-in is unlikely to be noticed quickly. A guard on site, or scheduled patrols where full-time cover is not needed, closes that gap.
Construction traffic mixing with live commercial use
As redevelopment work ramps up nearby, contractor vehicles and deliveries for active storage tenants will increasingly use the same roads and gates. Clear access control keeps the two separate and reduces the risk of an incident involving either.
| Why Choose Imperial Security In Mortlake
Local operating knowledge
We understand the layout around Mortlake High Street, including the multiple access points into the former Stag Brewery site and the mix of open storage, covered warehouse space and light industrial units now operating there. That means our guards know what normal traffic and deliveries look like on a given site before their first shift.
We cover Mortlake and neighbouring East Sheen, Barnes and Richmond, so cover can extend if your business operates across more than one site.
Flexible cover that scales with your site
Some warehouses need a guard permanently on the gate, others just need overnight patrols or cover during a specific construction phase. We size the service to match what the site actually needs rather than a fixed package.
