Security Grilles
Knightsbridge Locksmiths fits security grilles for homes and businesses across Knightsbridge and London — measured and finished to suit the property, not just bolted over the glass because it was quickest.
Not Every Security Grille Is the Same Job
A grille that suits a shopfront shutter behind glass is a different fit from one bolted across a ground-floor window on a period house, and a warehouse roller grille is a different job again. Telling us the opening type before we arrive means the right frame, finish and locking mechanism are already planned.
Windows & Doors
Fixed or removable grilles sized to the opening, finished to suit a period or modern property.
Shopfronts
Roller or lattice grilles that secure the frontage overnight without blocking the display by day.
Storage & Plant Rooms
Ventilated grilles for meter cupboards, bin stores and plant rooms that still need to breathe.
What Our Security Grille Fitters Can Do For You
From a single window grille to a full shopfront shutter, one engineer sees the job through — measured and quoted before we start, fitted and finished properly.
Frames, Finishes and What Actually Matters
A grille is only as good as its weakest fixing — a heavy-gauge lattice on soft, undersized wall plugs is no better than a token deterrent. We fit and finish every grille to hold under real force, not just to look secure from the pavement.
Solid steel construction
Lattice and bar grilles built from steel gauged for the opening, not a lightweight stock size.
Fixings that actually hold
Anchored into sound masonry or framing, not just screwed into plaster or render.
Fixed or removable options
Permanent grilles for maximum security, or collapsible and removable versions where daily access matters.
Weatherproof, finished properly
Powder-coated or galvanised finishes that hold up outdoors, not bare metal left to rust.
Built on Proof, Not Promises
Surveyed before it's quoted
We measure the opening and check the fixing surface before any figure is given, not after.
Priced before work starts
Grille type, finish and fixing method are quoted upfront — no surprises on the invoice.
Fully licensed and insured
Our engineers carry ID and full public liability cover on every job, residential or commercial.

Security Grille Installation Across Our Coverage Areas
Openings change street by street across Central London — here's how a security grille job looks in four of the areas we cover most.

Security Grilles Knightsbridge (SW7)
Period conversions around Beauchamp Place and mews houses off Brompton Road usually call for a discreet, removable grille rather than a permanent lattice that fights the frontage. We survey each property individually rather than fitting a standard size.

Security Grilles Chelsea & Belgravia (SW3 / SW1X)
King's Road retail units and the offices around Eaton Square both fall inside our patch. Roller and lattice grilles here are sized to secure the frontage overnight without blocking a display window by day.

Security Grilles South Kensington (SW7)
Dense with converted flats around Exhibition Road and Gloucester Road, where ground-floor windows benefit most from a fitted grille — the openings a break-in is most likely to target first.

Security Grilles Pimlico & Belgravia (SW1P / SW1E)
The terraced streets around Warwick Way and Eaton Square often need rear-access grilles as much as front ones, where a side return or back door is out of sight from the street.
Where We Fit Security Grilles Across Central London
Our core ground is Knightsbridge, worked from 4 Montpelier Street, SW7 — reaching every SW1 postcode plus the streets and neighbourhoods that make up Belgravia, South Kensington and Chelsea, with wider security grille cover across Central London.

FAQs — Security Grilles
Will a security grille make my window look like a prison?
Not if it's specified properly. Lattice and slimline bar grilles in a matching finish are far less obtrusive than the heavy warehouse-style grilles people picture, and can be fitted internally where appearance matters most.
Can a grille be removed in an emergency?
Yes — removable and quick-release grilles are available for rooms that need a fire escape route, fitted so they don't compromise means of escape.
Do you fit grilles for shops as well as homes?
Yes — shopfront roller and lattice grilles are sized to secure the frontage overnight without blocking a display window by day.
How long does fitting take?
A single window or door grille is usually completed within a few hours. Shopfront shutters and multi-opening jobs depend on scale, and we'll give a realistic timeframe at the survey.
Will a grille affect my home insurance?
It can help — some insurers offer better terms on ground-floor properties with fitted grilles. Worth checking your policy once the grille's in.
Do you cover installations outside Knightsbridge?
Yes — alongside our core Knightsbridge, Chelsea and Belgravia ground, we fit security grilles for homes and businesses across Central London and the surrounding boroughs.
