What affects the price of aluminium sliding doors
Size and number of panes. The biggest driver is the overall size and how many sliding panes you need. Wider openings use more aluminium and larger, heavier glass units, and very wide spans may need a structural beam above the opening, which is a separate builder cost.
Slim sightlines. Slimline systems with ultra-narrow frames cost more than standard profiles because they use higher-grade engineering to hold large panes of glass on a thin frame.
Glass specification. Standard double glazing is the baseline. Toughened safety glass, low-iron glass for clarity, solar-control coatings, acoustic glass and triple glazing all add cost.
Colour and finish. A standard RAL colour such as anthracite grey is usually included or a small upcharge. Dual colour, textured or non-standard finishes add cost.
Configuration and threshold. The number of tracks, the direction of slide, and a flush or low threshold for level access all affect the build.
Supply only vs supply and fit
Supply only is the lowest-cost route: you receive the made-to-measure door and use your own fitter, saving the installation margin, typically £1,000 to £2,000. Supply and fit costs more but the installer handles measuring, fitting and sign-off. If you already have a trusted builder on your project, supply only is almost always the better value.
How to keep the cost down
Buy supply only and use your own fitter, stick to a standard RAL colour such as anthracite grey, choose the pane count for the opening you actually have, and order direct from the manufacturer rather than through a retailer that adds a margin. Getting an exact online price up front also avoids estimates that creep up.
Sliding doors vs bifold doors
Sliding doors give you large, uninterrupted panes of glass and a slim, minimal look, while bifolds fold right back to open the whole wall. Sliding doors often work out slightly cheaper than an equivalent bifold and are a popular choice where the view matters most. If you are comparing the two, see our guide to how much aluminium bifold doors cost.
