What is the price of grille lock replacement in Hatfield?

Most grille lock replacements in Hatfield cost £150 to £354 including VAT (£125 to £295 plus VAT) per lock fitted. Upgrades such as quick-release or restricted-key cylinders are priced before work goes ahead.

Grille lock replacement means fitting a new cylinder, lock body or complete lock box to an existing security grille. It is the quick fix for lost keys, worn or seized locks and moving into a property with unknown keys, and a chance to upgrade to a stronger or quick-release lock.

What is included

  • Replacement cylinders and lock bodies
  • Complete lock box replacement
  • Upgrades to higher-security cylinders
  • Keyed-alike and master-key suites
  • Lock work on most grille makes
  • Quick-release conversions for escape windows

Visits in Hatfield and nearby

Hatfield is about 10 miles from Watford, the main centre for Hertfordshire. We can arrange visits across the AL10 district and in nearby places such as Welwyn Garden City and St Albans.

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

Typical reasons to book:

  • New occupants with unknown key holders
  • Sites wanting one key for every grille
  • Bedroom grilles needing a keyless release
  • Lost or stolen keys

Things to think about

Like for like or upgrade

If the grille is sound, a better cylinder is a cheap upgrade.

Key control

Restricted key systems limit who can have copies cut.

Planning and safety in England

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.

  2. Choose like-for-like or upgrade
  3. Fitting and testing
  4. Keys and handover
