How much do window security grilles cost in Farnham?

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
- Made to measure for the reveal, including bays and splayed reveals
- Works with uPVC, aluminium, timber and steel windows
- Anti-tamper fixings into masonry or a fabricated subframe
- Fitted inside the glass by default; external options for recessed or plain openings
- Retractable, fixed or removable designs
- Lock positioned to clear window handles and restrictors

Surrey is mostly suburban and commuter housing, from interwar semis to large detached homes, with busy town centres such as Guildford and Woking.
Typical places for this kind of grille include:
- Rear windows facing alleys and gardens
- Outbuildings, workshops and garages with glazing
- Flats with windows onto shared walkways
- Offices and shops with side or rear windows
Things to decide before you order
Depth in the reveal
Tracks need a few centimetres of flat reveal. Where the frame sits flush with the wall, the grille can be fixed to a slim subframe instead.
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.
Rules that apply in England
Bedroom and escape windows
Approved Document B (fire safety) expects many habitable rooms in houses, especially first-floor rooms, to have an emergency escape window with an unobstructed opening of at least 0.33 m², at least 450 mm high and 450 mm wide, with the bottom of the opening no more than 1,100 mm above the floor. We only fit grilles over escape windows with a release that opens from inside without a key.
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.

Window security grilles in Farnham: questions
Can you survey in Farnham and nearby towns?
Yes. Surveys in Farnham, Aldershot, Fleet and elsewhere in Surrey are booked around installer availability.
Should window grilles go inside or outside?
Inside in most cases. Internal grilles avoid weathering, are harder to attack, keep the outside of the building unchanged and rarely need planning permission. External grilles suit openings with no internal depth.
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.
