How this calculator works

Yes — replacement external doors are notifiable for thermal performance and, where relevant, means of escape. Use a FENSA or Certass registered installer and the certificate is handled for you; otherwise you must apply to building control yourself, which costs more and is often forgotten until you come to sell.
For a front door, generally yes. Composite doors have a solid core, better insulation and better security ratings, and they hold colour longer. uPVC remains a sensible economical choice for a back or side door that is less exposed and less visible.
Ask for a door tested to PAS 24 with a 3-star cylinder (TS 007) or a 1-star cylinder combined with 2-star security handles. Many home insurers ask about this, and it is the difference between a door being opened in seconds by snapping and it holding.
A straightforward like-for-like replacement is 3–5 hours. If the opening needs resizing, or a new lintel is required, allow a full day or more.
