What to think about first
Solar control
South-facing doors can overheat. Adding solar control glass at the same time keeps rooms cooler.
Laminated inner or both panes
A laminated inner pane is the usual security upgrade. On very exposed doors both panes can be laminated.
Consents and safety: England
Planning permission
Changing the glass in an existing window or shopfront does not usually need planning permission, because the building looks much the same afterwards. A new or altered shopfront, or security features added to the outside of a building, may need planning permission from the council. Bollards or barriers on the pavement need the highway authority's consent, which is normally the council.
Safety glass in critical locations
In England, section 5 of Approved Document K treats glazing in doors and in side panels within 300 mm of a door edge, from floor level up to 1,500 mm, and any other glazing below 800 mm, as a critical location. Glass there should break safely, be robust, or be guarded. Laminated or toughened glass meeting BS EN 12600 class 3 is the usual answer, rising to class 2 for door and side-panel panes wider than 900 mm.

Patio and bifold door security glass in Central London: questions
Do you cover Pimlico as well as Central London?
Yes. As well as Central London, we can arrange surveys in nearby Pimlico, Islington and Camden Town. Dates depend on installer availability.
Is patio door glass already safety glass?
It should be, because doors are critical locations. Most is toughened, which is safe but not secure. Adding a laminated pane makes it both.
Can you replace just one pane of a bifold?
Yes. Each leaf takes its own unit, so we can upgrade one leaf or all of them.
Can sliding doors be lifted out?
Older sliding doors without anti-lift blocks can be. We check for this at the survey and can fit blocks at the same visit.
