Replacing your front or back door is one of the most impactful home improvements you can make. It enhances kerb appeal, improves energy efficiency, and most importantly, strengthens your home's security. This guide covers everything UK homeowners need to know before embarking on a door replacement project.
When Should You Replace Your Door?
Several signs indicate it is time for a new door. Persistent draughts around the frame suggest the door or seal has failed. Difficulty locking or unlocking, warping, visible damage, or simply an outdated appearance are all valid reasons. If your door is more than 15-20 years old, modern replacements offer significantly better security and insulation.
Understanding Door Types
UK homeowners have several excellent options:
- Composite doors — The premium choice. Combines timber, uPVC, and GRP for exceptional strength, insulation, and aesthetics. Typically last 30+ years.
- uPVC doors — Affordable, low-maintenance, and thermally efficient. Ideal for back doors and side entrances.
- Solid timber doors — Traditional appearance with excellent insulation. Require regular maintenance but offer timeless appeal.
- Aluminium doors — Slim frames maximise glass area. Popular for patio and bi-fold installations.
Security Ratings Explained
Look for doors with PAS 24 certification, which tests resistance against physical attack. Secured by Design accreditation indicates police-preferred specifications. For the frame, timber cores in composite doors offer the best resistance to forced entry.
What Does Door Replacement Cost?
Expect to pay £600-£1,500 for a quality composite front door supply and installation. uPVC options range from £400-£800. Premium timber doors can exceed £2,000. Always obtain multiple quotes and verify that your installer offers a guarantee on both the door and fitting.
Locks and Hardware
A new door deserves quality hardware. We recommend British Standard mortice deadlocks (BS3621), anti-snap cylinders, and reinforced hinges. Multipoint locking systems on composite and uPVC doors engage multiple points around the frame, providing superior security compared to single-point locks.
Finding a Trusted Installer
Choose installers registered with CERTASS or FENSA for self-certified compliance with building regulations. Check reviews, request references, and ensure they carry adequate insurance. A professional installation is as important as the door itself — poor fitting undermines even the highest-rated door.
