Front doors
A new front door fitted costs roughly £700 to £2,800 depending on material. Composite is the usual recommendation for security and insulation, uPVC is the budget option, aluminium suits contemporary houses, and timber is often required on listed or conservation properties.
This page is about choosing between materials. If you already know you want composite, the detail you need is on the composite doors page.

The four materials, compared honestly
- Composite, £900 to £2,350. A solid core with a tough GRP skin. The best all-round combination of security, insulation and low maintenance, and the most common recommendation for a front door.
- uPVC, £700 to £1,400. The cheapest route. Lighter and less solid than composite, and less convincing underfoot, but a sound choice on a budget.
- Aluminium, £1,400 to £2,800. Slim, strong and contemporary, with large glazed panels possible. Suits modern elevations and extensions.
- Timber. Usually the only option accepted on a listed building. Needs maintenance, and can be repaired rather than replaced.
Security is mostly the lock and the frame
People choose a door on appearance and then assume the security came with it. In practice the cylinder, the multi-point lock and the frame fixings do most of the work, and a good door on a poor frame is not a secure door.
Ask whether the doorset is tested to PAS 24, and whether the cylinder is anti-snap to TS007 three-star or Sold Secure Diamond. Cylinder snapping remains one of the most common ways front doors are defeated.
Glass, sidelights and privacy
Glazed panels let light into a hallway that often has no other source, which matters more than people expect. The trade-offs are privacy and security.
Obscure glass handles privacy. For security, any glazed area within reach of the lock should be laminated rather than toughened, because laminated glass stays in place when broken and does not give access to the handle.
Front doors: common questions
- What is the most secure front door material?
- Composite and aluminium both perform well, but the material matters less than the locking system, the cylinder and how the frame is fixed. A PAS 24 doorset with an anti-snap cylinder is the specification to ask for.
- Do I need planning permission for a new front door?
- For a straightforward replacement on an ordinary house, normally no. Listed buildings need listed building consent, and conservation areas with an Article 4 direction may need permission. Flats have different rules again.
- How long does fitting a front door take?
- A straightforward replacement into an existing opening is usually a few hours. Altering the opening size, or making good around a different frame, extends it into a longer job.
