Window security grilles in Hatfield

What is the price of window security grilles in Hatfield?

Most window security grilles in Hatfield fall within £414 to £954 including VAT (£345 to £795 plus VAT) per window for supply and fitting. We confirm a fixed price in writing after a free survey, before anything is ordered.

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 you can specify

Anti-tamper fixings into masonry or a fabricated subframe
Quick-release escape handle for bedroom and upstairs windows
Made to measure for the reveal, including bays and splayed reveals
Works with uPVC, aluminium, timber and steel windows
Retractable, fixed or removable designs
Fitted inside the glass by default; external options for recessed or plain openings

Fitting in Hatfield and nearby

We arrange surveys and fitting in Hatfield and across the AL10 postcode district, as well as in nearby Welwyn Garden City (3 miles) and St Albans (5 miles). Dates depend on installer availability.

Hertfordshire mixes the garden cities of Letchworth and Welwyn, post-war new towns such as Stevenage, and historic centres like St Albans.

This type of grille suits:

Rear windows facing alleys and gardens
Outbuildings, workshops and garages with glazing
Offices and shops with side or rear windows
Flats with windows onto shared walkways

Questions we will ask at the survey

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.

Colour

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

Planning and safety in England

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.

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.

Window security grilles in Hatfield: questions

Do you cover Welwyn Garden City as well as Hatfield?

Yes. As well as Hatfield, we can arrange surveys in nearby Welwyn Garden City, St Albans and Potters Bar, and elsewhere in Hertfordshire.

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.

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.

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.
