A standard front door replacement takes one full working day, but complex jobs can stretch to two days
If you are planning a new front door, the first question is often about time. A like-for-like replacement of a composite or uPVC door into an existing, undamaged frame is the most common job. A single tradesperson typically completes this in 4 to 8 hours (FENSA, 2026).
A standard front door replacement takes 4 to 8 hours for a like-for-like swap of a composite or uPVC door. For frame repairs, structural work, or timber doors, expect up to two full days.
- Like-for-like composite or uPVC replacement takes 4-8 hours.
- Frame repairs or structural work adds a full day.
- Composite doors install fastest at 4-6 hours pre-hung.
- Timber doors need on-site planing, often requiring 2 days.
- Steel or aluminium doors need two-person lifting and 6-8 hours.
- A standard front door replacement takes one full working day, but complex jobs can stretch to two days
- The material you choose directly controls the installation timeline
- A new-build or enlarged opening adds at least half a day for frame fitting
- Quick numbers, typical installation times by door type and job scope
- The fastest route is a pre-hung composite door fitted by a FENSA-registered installer

If the existing frame is rotten or the opening needs structural repair, the job takes longer. You should expect a second day for joinery work and weatherproofing. FENSA industry guidance states that frame repairs or replacements routinely add a full day to the installation schedule (FENSA, 2026).
The material you choose directly controls the installation timeline
Composite doors arrive pre-hung in a factory-fitted frame. This means on-site work is limited to fitting the assembled unit into the opening. A composite door typically takes 4 to 6 hours to install (Glass and Gazing Federation, 2026).
uPVC doors are similar to composite in design. Hinge alignment and weather seal adjustment can add 30 to 60 minutes to the job. Timber doors require site-fitted frames and on-site planing. This can push the installation to 8 to 10 hours, and often requires a second day. Steel or aluminium doors are heavier. They need two-person lifting and extra time for anchoring. Budget 6 to 8 hours for a steel or aluminium door installation (Glass and Gazing Federation, 2026).
A new-build or enlarged opening adds at least half a day for frame fitting
Replacing the entire door frame, not just the door slab, adds 2 to 3 hours for cutting, shimming, and sealing. If you are enlarging or moving the door opening, the job becomes significantly larger. This requires structural timberwork, lintel installation, and plastering. The NHBC standards for door opening installation confirm that this type of work is typically a two-day job (NHBC Technical Manual, 2026).
Quick numbers, typical installation times by door type and job scope
The table below shows estimated installation times based on aggregated data from FENSA and GGF member installer surveys (FENSA, 2026; GGF, 2026). These are typical figures. Your actual time may vary depending on the specific installer and site conditions.
| Door type | Job type | Single fitter (hours) | Two-person crew (hours) |
|---|---|---|---|
| Composite | Like-for-like | 4–6 | 3–4 |
| uPVC | Like-for-like | 5–7 | 3–5 |
| Timber | With frame replacement | 8–10 | 5–7 |
| Steel or aluminium | Like-for-like | 6–8 | 4–6 |
The fastest route is a pre-hung composite door fitted by a FENSA-registered installer
Pre-hung units arrive with hinges, locks, and seals already factory-fitted. There is no on-site assembly. A FENSA-registered installer can complete a pre-hung composite swap in under 5 hours (FENSA, 2026).
MCS certification is relevant only if the door includes integrated energy-performance features, such as built-in solar panels. For standard doors, FENSA or Certass registration is the key quality mark. These schemes mean the installer can self-certify building regulations compliance. This avoids a separate council inspection and any associated waiting time.
Your installer’s certification tells you whether the job will be done in one visit
FENSA or Certass registration means the installer self-certifies building regulations compliance. This removes the need for a separate council inspection, so there is no wait for sign-off after the job is finished. GOV.UK guidance confirms that replacement doors must comply with building regulations, and a FENSA or Certass certificate is your proof of compliance (GOV.UK, 2026).
Gas Safe Register is not relevant for door installation. TrustMark accreditation adds a layer of consumer protection but does not shorten the job. The installer’s registration with FENSA or Certass is the main factor that determines whether the work can be completed and signed off in a single visit.
How long does a front door installation take? The plain answer for a typical UK home
For a standard-sized, like-for-like replacement of a composite or uPVC door in an existing sound frame, the job takes 4 to 6 hours. For a timber door with frame replacement, the job takes 8 to 10 hours. For any job requiring structural work or opening enlargement, expect 2 full days. These times assume a single experienced fitter. A two-person crew can reduce a standard job to 3 to 4 hours (FENSA, 2026).
How to choose a front door material
Weather, access, and old-door disposal can add 1 to 2 hours to your total
Poor weather, such as rain or high wind, slows sealant curing. This may require a second visit for finishing. Narrow staircases or parking restrictions add time for carrying materials. Budget an extra hour for access issues. Disposal of the old door takes 30 to 60 minutes. Most installers include skip costs in the quote, but removing heavy steel or timber doors takes additional time. TrustMark consumer guidance on door installation logistics confirms these factors (TrustMark, 2026).

Frequently Asked Questions
A composite door typically takes 4 to 6 hours to install. This is because it arrives pre-hung in a factory-fitted frame, so on-site work is limited to fitting the assembled unit, per the Glass and Gazing Federation (2026).
A uPVC door takes 4 to 8 hours to install. Hinge alignment and weather seal adjustment can add 30 to 60 minutes compared to a composite door, according to FENSA (2026).
A timber front door installation takes 8 to 10 hours, often requiring a second day. This is because the frame must be site-fitted and the door planed on site, as noted by the Glass and Gazing Federation (2026).
A front door installation with a new frame takes 6 to 11 hours for a like-for-like replacement. Replacing the entire frame adds 2 to 3 hours for cutting, shimming, and sealing, per FENSA (2026).
Yes, a standard front door replacement can be installed in one day if it is a like-for-like swap into an undamaged frame. Complex jobs like frame repairs or opening enlargement typically require a second day, per NHBC Technical Manual (2026).
