How much do window security grilles cost in Merseyside?

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
- Lock positioned to clear window handles and restrictors
- Fitted inside the glass by default; external options for recessed or plain openings
- Powder-coated in white, black or anthracite to sit with the frame colour
- Works with uPVC, aluminium, timber and steel windows
- Anti-tamper fixings into masonry or a fabricated subframe
- Quick-release escape handle for bedroom and upstairs 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
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.
Listed buildings and conservation areas
Listed buildings need listed building consent for works that affect their character, which can include internal grilles and their fixings. In conservation areas, councils look closely at anything fitted to the outside. We recommend speaking to the council's conservation officer before ordering.

Window security grilles in Merseyside: questions
Which towns in Merseyside do you cover?
We can arrange work anywhere in Merseyside, including Liverpool, Birkenhead, St Helens, Southport and Wallasey, and in other towns across the area.
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.
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.
