Are aluminium sliding doors right for your Farnham home?
Before you settle on a door type, it helps to know what aluminium sliding doors do well and what to check before you order.
Where a Farnham property already has aluminium windows, matching the door colour and frame profile keeps the back of the house looking consistent.
Whether you live in Farnham or elsewhere in Surrey, a lawn or patio sitting just below floor level can still take a low threshold, provided an outside drainage channel or a fall away from the door is planned.
- Narrow aluminium frames and meeting stiles put more of the opening into glass, so you see more garden and less frame than with a uPVC door of the same size.
- Because the panels slide rather than swing, nothing opens into the room or across the patio, leaving space for a dining table, sofa or planters right up to the glass.
- A polyamide thermal break inside every profile separates the cold outer metal from the warm inner face, cutting heat loss and reducing the risk of condensation forming on the frame.
Light and sun in Farnham
At the latitude of Farnham, the midday sun climbs to about 62° in late June but only about 15° in late December, when daylight lasts around 7 h 52 min against 16 h 35 min in midsummer. A south-facing aluminium sliding door lets that low winter sun deep into the room; on a west or south elevation, solar-control glass keeps summer afternoons comfortable.

From survey to fitted door in Farnham
Once the opening is measured, nothing is ordered until you sign off the specification. Lead time is typically 4–6 weeks from survey sign-off. Our fitters protect floors, remove the old door, install and seal the new one and leave the area clean — usually 1 day for a two-panel straight swap; 1–2 days for larger doors for a door like this.
Do you need approval in Farnham?
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
Options to consider for your aluminium sliding door
- Panel configuration. Two, three or four panels, with the sliding panel on the left, right or both sides to suit how you use the room.
- Colours. Standard shades such as anthracite grey, black and white, or a special RAL colour for an extra charge.
- Handles and locks. Slim pull handles or lever handles in matching or contrasting finishes, with an enhanced security locking pack available.
Questions about aluminium sliding doors in Farnham
Is the price different in Farnham?
No. Guide prices for aluminium sliding doors are the same across mainland Britain, including Farnham. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
Are aluminium sliding doors secure?
Aluminium sliding doors can be very secure when they combine multi-point hook locks, anti-lift blocks and laminated glass. Systems are available tested to PAS 24, the UK enhanced security standard for doorsets, and an enhanced security locking pack can be added to your quote. Most systems are glazed from the inside, so the glass cannot be unclipped from outside.
How long do aluminium sliding doors take to arrive?
Aluminium sliding doors typically take 4–6 weeks to make after you sign off the surveyed specification, because each door is built to measure and powder coated to order. Fitting a straight swap of a two-panel door typically takes 1 day, and larger doors 1–2 days. These are typical times rather than promises, and we confirm a date once the order is placed.
Do aluminium sliding doors need Building Regulations approval?
In England, replacement sliding doors are controlled fittings, so the work is either carried out by an installer registered with a competent person scheme, who self-certifies and notifies, or notified to Building Control. The glass must be safety glazing to BS EN 12600. Forming or widening an opening is structural work needing its own application and calculations. Wales, Scotland and Northern Ireland have their own rules.
