Grille lock replacement and upgrades in Norfolk: what will it cost?

Grille lock replacement and upgrades in Norfolk typically costs £150 to £354 including VAT (£125 to £295 plus VAT) per lock, supplied and fitted, depending on the lock type. The price is confirmed before work starts.

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 we look at

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

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

Keyed alike

One key for all grilles is convenient for homes and small shops.

What the rules say 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.

Grille lock replacement and upgrades in Norfolk: questions

Which towns in Norfolk do you cover?

We can arrange work anywhere in Norfolk, including Norwich, Great Yarmouth, King's Lynn, Thetford and Dereham, and in other towns across the area.

Is a better cylinder worth it?

On a grille that is otherwise sound, a higher-security cylinder is an inexpensive way to raise resistance to lock attack.

Can all my grilles use the same key?

Yes, by keying the new cylinders alike.

I have lost my grille key. What can I do?

We can open and replace the lock so you have new keys and know who holds them.
