Fully-finished and plain internal doors ready to install
The extensive choice of colours and styles makes it easy to find the right type for your home. No matter your design aesthetics, you’ll be able to choose from a range of sizes, from standard to bespoke doors. White doors are an excellent choice in small homes, as they create the illusion of light and really open up a room. Looking for a modern colour? A grey door adds a contemporary design to any space. You can also find unfinished internal doors to decorate yourself.
Preventing the spread of fire is important, which is where our range of FD60 fire doors comes in. These single internal doors are fire-rated and offer up to 60 minutes of protection from fire. This gives you and your family ample time to evacuate the property in an emergency. We also offer an extensive range of FD30 fire doors.
Some of our most popular doors include our oak door range. These give you a classic look and a sturdy door to keep out the cold. The extensive glazed range is ideal for homes struggling to bring in natural light. The glazed glass doors give privacy while still allowing natural light in.

Exterior Doors FAQs
Choosing the right internal door depends on the room's purpose, your interior style and any performance requirements. Consider factors such as the door material, finish, glazing, core construction, size and whether you need an FD30 or FD60 fire door. Solid core doors are ideal for improved privacy and sound insulation, while glazed internal doors help maximise natural light.
Most internal doors are available in standard UK sizes, including 1981 x 610mm (24"), 1981 x 686mm (27"), 1981 x 762mm (30"), and 1981 x 838mm (33"). There are also metric and fire door sizes available. Measuring your existing door or opening accurately before ordering will help ensure the best fit and reduce the need for trimming.
Solid core internal doors are heavier, stronger and offer better sound insulation and durability, making them ideal for busy households and high-traffic areas. Hollow core doors are lighter and more affordable but provide less acoustic performance and are generally better suited to low-use rooms.
Many internal doors can be trimmed slightly to suit existing openings, but the amount depends on the manufacturer's recommendations. Fire-rated internal doors have strict trimming limits to maintain their certified fire performance. Always check the product specifications before making any alterations.
YYes. Glazed internal doors are an excellent option for bringing natural light into hallways, kitchens, living rooms and other areas where you want to create a brighter, more open feel. They are available with clear, frosted and decorative glass to suit different levels of privacy, and many are also available as fire-rated glazed internal doors for projects where safety and compliance are required.
