Visits in Chesterfield and nearby

Chesterfield is about 23 miles from Derby, the main centre for Derbyshire. We can arrange visits across the S40 district and in nearby places such as Staveley and Dronfield.

Derbyshire has gritstone cottages in the Peak District, Victorian terraces in Derby and Chesterfield, and retail parades in its former mining towns.

Typical reasons to book:

  • Bedroom grilles needing a keyless release
  • New occupants with unknown key holders
  • Sites wanting one key for every grille
  • Worn, stiff or seized locks

Things to think about

Keyed alike

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

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.

How it works

  1. Send a photo of the lock
  2. Choose like-for-like or upgrade
  3. Fitting and testing
  4. Keys and handover
