Window security grilles in Finchley

Window security grilles in Finchley: what will it cost?

Budget £414 to £954 including VAT (£345 to £795 plus VAT) per window for window security grilles in Finchley, supplied and fitted. Size, number of leaves, colour and access all move the price, which is fixed in writing after the survey.

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.

Fitting in Finchley and nearby

Finchley is about 7 miles from Central London, the main centre for Greater London. We can survey and fit across the N3 district and in nearby places such as Muswell Hill and Cricklewood.

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.

Common openings for window security grilles:

Ground-floor and basement windows
Flats with windows onto shared walkways
Outbuildings, workshops and garages with glazing
Rear windows facing alleys and gardens

Getting the right window grille for your building

Colour

White disappears against white frames, while black or anthracite suits darker frames and period sash windows.

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.

What the rules say in England

England

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.

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 Finchley: questions

Can you survey in Finchley and nearby towns?

Yes. Surveys in Finchley, Muswell Hill, Cricklewood and elsewhere in Greater London are booked around installer availability.

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.

Can I still open the window with a grille fitted?

With a retractable or removable grille, yes. Many fixed internal grilles also leave room to open the sash or casement behind them.

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.
