Benefits of Sliding Doors
Investing in sliding doors offers numerous advantages for UK homeowners, from practical benefits to aesthetic improvements. Here are the main advantages that make sliding doors worth considering:
Energy Efficiency
Double glazed patio doors are an excellent choice for reducing heat loss and improving energy efficiency, ultimately lowering your energy bills. With proper glazing, sliding doors can help maintain optimal indoor temperatures year-round.
Seamless Indoor-Outdoor Flow
Sliding doors create an elegant connection between your indoor and outdoor spaces, making them ideal for modern living and entertaining. They maximize your view while minimizing the barrier between inside and outside.
Bifold patio doors are another luxurious option that offers unobstructed views and increased natural light, enhancing the seamless access to outdoor spaces.
Durability and Longevity
Aluminium and uPVC sliding doors are designed to withstand the UK's unpredictable weather, ensuring longevity and reliability. Wooden doors, while offering a timeless aesthetic and energy efficiency, also require regular maintenance to prevent issues like rotting or warping.
Space-Saving Design
Unlike hinged doors that require clearance space to open, sliding doors operate parallel to the wall, making them perfect for smaller rooms, patios, or areas where space is at a premium. This efficient use of space allows for more flexible furniture arrangements and better flow in your living spaces.
Enhanced Security Features
Modern sliding doors come with advanced multi-point locking systems, toughened safety glass, and anti-lift mechanisms that provide excellent security for your home. Many designs now include multiple locking points along the frame for additional protection against forced entry.

Frequently Asked Questions About Sliding Doors in the UK
How much does it cost to install a sliding door in the UK?
Installing a sliding door in the UK, particularly for patio door installation, typically costs between £400 and £700, depending on factors such as the type of door, materials used, and adherence to building regulations. This price includes labour and fitting but excludes the cost of the door itself. For a complete installation including the door, most UK homeowners should budget between £1,000 and £2,200 total. Installation costs may be higher for custom sizes, premium materials, or installations that require structural modifications to your home.
Are sliding doors more expensive than regular doors?
Yes, sliding doors are typically more expensive than regular hinged doors due to their larger glass panels, advanced mechanisms, and more complex installation requirements. While a standard interior door might cost £100-£300, sliding patio doors start from around £500 for basic uPVC options and can exceed £3,000 for premium aluminium or timber designs. However, they offer significant benefits that justify the higher price: better aesthetics, increased natural light, improved energy efficiency, and seamless indoor-outdoor connections. The space-saving design also adds practical value that conventional doors can't match.

Do patio doors add value to your home?

UK estate agents estimate that well-designed patio doors can add 5-10% to a property's market value, particularly when they create a seamless connection to an attractive outdoor space.

The total cost to install a patio door in the UK, including materials and labour, typically ranges from £1,200 to £4,500. This variation depends on several factors: door material (uPVC being most affordable, followed by aluminium, with timber at the premium end), style (sliding doors versus bifold designs), size (standard versus custom dimensions), glazing options (double or triple glazing), and any additional features such as integrated blinds or special finishes. At Harrington Windows, we ensure unbeatable prices across our range, and new customers benefit from 20% off their first project, making quality patio doors more affordable.
