How much do window security grilles cost in Hounslow?

A window security grille is a steel barrier fitted across a window so that breaking the glass no longer gives a way in. It can be retractable, fixed or removable, and is most often fitted inside the reveal where it is protected and barely noticed from outside.
What goes into a window grille
- Anti-tamper fixings into masonry or a fabricated subframe
- Made to measure for the reveal, including bays and splayed reveals
- Fitted inside the glass by default; external options for recessed or plain openings
- Lock positioned to clear window handles and restrictors
- Powder-coated in white, black or anthracite to sit with the frame colour
- Retractable, fixed or removable designs

London's buildings range from Victorian and Edwardian terraces and mansion blocks to post-war estates, with long high streets of ground-floor shops below flats.
Typical places for this kind of grille include:
- Ground-floor and basement windows
- Outbuildings, workshops and garages with glazing
- Flats with windows onto shared walkways
- Rear windows facing alleys and gardens
Things to decide before you order
Retractable, fixed or removable
Match the grille to how often the window opens. Daily-use windows suit retractable; never-opened windows suit fixed; occasional windows suit removable.
Escape requirements
If the window is a designated escape window, the grille must open from inside without a key or tool. We fit quick-release locks for these.
Rules that apply in England
Grilles inside the glass
A grille fitted inside the glass does not normally need planning permission, because it does not materially change how the building looks from outside. If the building is listed, listed building consent may still be needed.
Grilles in rented homes
Landlords in England must keep rented homes free from serious hazards under the Housing Health and Safety Rating System, which includes fire. A grille that stops a tenant using an escape window can create a hazard, so grilles in rented homes should have keyless internal releases.

Window security grilles in Hounslow: questions
Do you cover Isleworth as well as Hounslow?
Yes. As well as Hounslow, we can arrange surveys in nearby Isleworth, Heston and Richmond, and elsewhere in Greater London.
Will a grille damage my window frame?
No. Grilles fix to the wall reveal or a subframe, not to the window itself, so the frame and its warranty are unaffected.
Do grilles work on bay windows?
Yes. A bay is usually treated as separate grilles for each face, or one grille following the bay on a curved or angled track.
Are window grilles safe in a bedroom?
They can be, provided the grille has a release that opens from inside without a key. Bedroom and upstairs windows often have to serve as escape routes, so we will not fit a key-only grille over a window you need for escape.
