Your Door Buying Guide: Everything You Need to Know 

Choosing the right doors for your home is more than just a functional decision—it’s an investment in security, aesthetics, and energy efficiency. Whether you’re replacing an old door, upgrading for better insulation, or picking doors for a new home, making an informed choice is key. 

This guide will walk you through different door types, materials, security considerations, and common mistakes to avoid, ensuring you select doors that are both stylish and practical. 

1. Why Your Door Choice Matters 

Doors are one of the first things people notice about your home. A well-chosen front door boosts kerb appeal, enhances security, and improves energy efficiency. Meanwhile, interior doors help define your space, reduce noise, and add character to your home’s design. 

Beyond aesthetics, a high-quality door can reduce heat loss, keeping your home warmer in the winter and cooler in the summer. Modern doors also come with advanced locking systems for added security, giving you peace of mind. 

2. Common Mistakes to Avoid When Buying Doors 

Choosing Style Over Function 

It’s easy to be drawn to a beautiful door, but if it doesn’t suit your needs, it’s not the right choice. For example, a glass-panelled front door might look stunning, but it could compromise security or privacy if not reinforced properly. 

Ignoring Energy Efficiency 

Many homeowners overlook insulation, only to regret it later when they experience drafts or high energy bills. Always check the U-value (lower values mean better insulation) and opt for composite or solid wood doors if energy efficiency is a priority. 

Going for the Cheapest Option 

While budget matters, cutting costs on materials can lead to long-term issues. A low-quality door may warp, crack, or fail to provide adequate security. Investing in a durable, well-constructed door will save you money in the long run. 

Overlooking Security Features 

Not all doors come with robust security features. Ensure your front and back doors have multi-point locking systems, reinforced frames, and high-security hinges to deter potential intruders. 

3. Types of Doors & Their Benefits 

Doors come in various styles and functions, so it’s important to pick the right one for each space in your home. 

Front Doors 

Your front door sets the tone for your home. A good front door should be secure, weatherproof, and stylish. Popular materials include: 

• Composite Doors – A mix of wood, uPVC, and insulating foam. These offer high security, durability, and energy efficiency. 

• Solid Wood Doors – Traditional and elegant, but require more maintenance to prevent warping. 

• uPVC Doors – Affordable and low-maintenance but can lack the durability of composite or wood options. 

Patio & Sliding Doors 

For access to gardens or balconies, sliding or bi-fold doors are popular. They allow for maximum light and easy outdoor access while maintaining a sleek, modern look. 

French Doors 

A timeless choice, French doors offer a classic design with glass panels, great for letting in light while maintaining a sophisticated look. 

4. Choosing the Right Door Material 

The material of your door impacts its longevity, maintenance, and security. Here’s a breakdown of the most common options: 

Composite 

Pros: High security, low maintenance, excellent insulation 
Cons: Higher upfront cost compared to uPVC 

Timber (Solid Wood) 

Pros: Beautiful, traditional, strong 
Cons: Expensive and requires regular maintenance 

uPVC (Unplasticised Polyvinyl Chloride) 

Pros: Affordable, lightweight, weather-resistant 
Cons: Less durable than composite or wood 

Aluminium 

Pros: Modern, durable, slim profiles allow for large glass panes 
Cons: Can be more expensive than other options 

5. Security Considerations When Buying Doors 

A door’s security features should never be an afterthought, especially for external doors. Look for: 

• Multi-point locking systems – More secure than standard locks. 

• Reinforced hinges – Prevent forced entry. 

• Toughened or laminated glass – If your door has glass panels, make sure they are impact-resistant. 

• Anti-snap cylinders – Prevent lock snapping, a common burglary technique. 

For extra security, consider adding a smart lock or video doorbell system for added peace of mind. 

6. Energy Efficiency & Insulation 

A well-insulated door reduces heat loss and saves on energy bills. Here’s what to look for: 

• Airtight seals – Prevents drafts and cold air leaks. 

• Double or triple glazing (for doors with glass panels) – Improves insulation. 

• Insulating core – Composite and timber doors provide better thermal performance than hollow uPVC doors. 

Look for Energy Performance Certificates (EPC ratings) or BFRC-rated doors to ensure high efficiency. 

7. Cost & Budget Considerations 

The price of doors varies depending on material, security features, and installation. Here’s a rough guide: 

Door type & Average Door Cost (Supply only): 

UPVC Front Door: £300 – £700 
Composite Front Door: £700 – £2,000 
Solid Wood Door: £900 – £3,000 
Sliding Patio Doors: £900 – £2,500 

Installation typically adds £100 – £500 per door, depending on complexity. 

Final Thoughts 

Choosing the right doors for your home enhances security, efficiency, and aesthetics. By considering materials, security features, and insulation, you’ll make a smart investment that stands the test of time.
