A solid external door costs roughly £1,200 installed, but the cheapest option starts under £200 – the difference is security, insulation, and lifespan.
If you are replacing a front or back door in 2026, the price range is wide. A basic uPVC door can be fitted for around £400, while a premium composite or hardwood timber door will cost three or four times that. The reason for the gap is not just appearance but measurable performance in security, thermal efficiency, and how long the door will last before needing replacement.
Composite doors cost £800–£1,600 installed, averaging £1,200 in 2026. uPVC is the cheapest at £400–£800, while timber hardwood runs £1,200–£2,500. Choose composite for the best balance of security, insulation, and lifespan.

The average installed cost for a standard composite front door in 2026 is approximately £1,200, according to Checkatrade (Checkatrade, 2026). That figure covers supply, fitting, and disposal of the old door. At the budget end, a basic unglazed uPVC door can be bought for under £200, but installation and ironmongery will push the total to around £400–£800.
Composite doors offer the best balance of security and insulation for most UK homes
Composite doors are the dominant choice in the 2026 UK replacement market. They consist of a glass-reinforced plastic (GRP) skin over a solid foam core, usually polyurethane or a similar insulating material. This construction gives them a typical U-value of around 1.2 W/m²K, measured using the industry standard BS EN ISO 10077-1 (BRE, 2026).
The installed cost for a composite door in 2026 ranges from £800 to £1,600, with the average around £1,200 (Checkatrade, 2026). Multi-point locking systems are standard, and most composite doors meet Secured by Design standards, which require PAS 24:2022 testing (Secured by Design, 2026). Warranties typically run 10 to 15 years, and some manufacturers such as Solidor and Rockdoor offer 20-year guarantees on the door slab.
The main advantages are low maintenance (no painting needed), good insulation, and high resistance to forced entry. The main disadvantage is the upfront cost, which is higher than uPVC or basic timber.
uPVC doors are the cheapest option but have a shorter lifespan
uPVC doors are the most common type of external door in the UK by volume, largely because of their low price. An entry-level unglazed uPVC door costs £200 to £500, and installed prices in 2026 range from £400 to £800 (Checkatrade, 2026).
The typical lifespan of a uPVC door is 15 to 20 years before warping, fading, or cracking becomes noticeable. The U-value for a modern triple-glazed uPVC door is approximately 1.4 to 1.6 W/m²K (BRE, 2026). Standard uPVC doors are less secure than composite or steel unless reinforced with a steel core, which adds cost. If the welded frame cracks, the entire door must be replaced because the frame is not repairable.
uPVC is the budget choice, but it is not the best option for security or long-term insulation. It is suitable for back doors or rental properties where cost is the main factor.
Timber doors provide classic aesthetics but require ongoing maintenance
Timber doors are available in softwood (typically pine) or hardwood (typically oak). A softwood external door costs £150 to £400, and a hardwood door costs £400 to £1,200, according to the Timber Trade Federation (Timber Trade Federation, 2026). Installed prices add fitting costs, which vary regionally.
The U-value of a solid timber door is around 2.0 to 2.5 W/m²K (BRE, 2026), which is significantly worse than composite or modern uPVC. This means more heat is lost through a timber door than through a composite door of the same size. Timber doors must be painted or varnished every three to five years to prevent rot (Wood Protection Association, 2026).
Timber doors are not automatically fire-rated. If you need a fire door between a house and an integral garage, check for FD30 or FD60 certification. Timber is the best choice for period properties where appearance matters more than insulation or maintenance cost.
Steel doors are the most secure but can dent and rust
Steel doors offer the highest resistance to forced entry because the metal skin is difficult to break through. A typical steel door costs £400 to £900 installed in 2026 (Checkatrade, 2026). The U-value is approximately 1.5 to 2.0 W/m²K (BRE, 2026), which is often lower than composite because the insulating core is thinner.
Steel doors are susceptible to dents from impact, and if the galvanised coating is scratched, rust can develop. They are not suitable for coastal areas unless specified with a marine-grade finish. Steel doors are most common in commercial settings or high-security residential applications where burglary risk is high.
Quick numbers – cost, U-value, and lifespan for the four main door types
| Door type | Typical installed cost (2026) | U-value (W/m²K) | Average lifespan (years) | Security standard |
|---|---|---|---|---|
| Composite | £800–£1,600 | ~1.2 | 20+ | Secured by Design / PAS 24 |
| uPVC | £400–£800 | ~1.4–1.6 | 15–20 | PAS 24 (with steel core) |
| Timber (hardwood) | £400–£1,200 | ~2.0–2.5 | 20–30 (with maintenance) | PAS 24 (if specified) |
| Steel | £400–£900 | ~1.5–2.0 | 15–25 | Secured by Design / PAS 24 |
U-values are based on BS EN ISO 10077-1 (BRE, 2026). Security standards are from PAS 24:2022 and Secured by Design 2026 guidance (Secured by Design, 2026). Lifespan figures are typical for a well-maintained door in a sheltered location.
What is the best type of door for a UK home in 2026? Composite – for most houses
For most UK homes in 2026, a composite door offers the best combination of insulation, security, lifespan, and low maintenance. The average U-value of 1.2 W/m²K is better than timber or steel, and the multi-point locking system meets Secured by Design standards. A composite front door for a standard three-bedroom semi-detached house costs roughly £1,200 installed and will pay for itself in energy savings over 10 to 15 years compared to an old single-glazed timber door (Energy Saving Trust, 2026).
If your budget is tight, uPVC is the cheapest option but expect a shorter lifespan and lower security. For period properties, timber is the best aesthetic match but requires regular painting. For security-critical applications such as a back door in a high-crime area, steel is the strongest choice.
guide to choosing the best front door for security
MCS certification is not required for doors – but FENSA or TrustMark registration is essential for compliance
Under Building Regulations Part L (conservation of fuel and power) in England and Wales, any replacement external door must meet minimum thermal performance standards. The installer must be registered with a competent person scheme such as FENSA (Fenestration Self-Assessment Scheme) or equivalent (GOV.UK, 2026). If you use an unregistered installer, you will need to apply for building regulation approval separately.
TrustMark is a government-endorsed scheme for all home improvement trades. Check that your door installer is TrustMark registered before paying a deposit (TrustMark, 2026). For fire doors, such as the door between a house and an integral garage, the installer must be certified to install FD30 or FD60 doors. Check for UKAS-accredited certification such as BM Trada (BM Trada, 2026).
MCS (Microgeneration Certification Scheme) applies only to renewable energy installations such as heat pumps or solar panels. It is not relevant for door installation.
