How Much Do Rehau Slinova Sliding Doors Cost in the UK?

Rehau Slinova sliding patio doors are the uPVC alternative to an aluminium slider, and the question we hear most from homeowners comparing the two is how the price actually stacks up. There is no single number that applies to every opening, because Slinova pricing moves with size, configuration and specification. This guide sets out the factors that shape the cost of a Slinova installation and where to get a figure for your specific project.

Why Slinova Pricing Varies So Much

A Slinova quote is built from several independent variables rather than a flat rate per door. The overall width and the number of panels, the glazing specification, the colour and finish, and the complexity of the opening all move the total in different directions, which is why two Slinova installations on paper-similar houses can land at very different figures. The only reliable way to see where your project sits is a survey, because Slinova is fabricated and installed to the exact opening rather than sold as a stock size.

What Drives the Price Up

A wider configuration with more sliding panels naturally costs more than a compact two-panel door, simply because there is more profile, more glass and more hardware in the run. Upgraded glazing, such as enhanced solar control or acoustic glass, adds to the specification. A foiled or dual-colour finish, matching an existing frame colour or a bespoke RAL shade, sits above standard white or anthracite. Structural work at the opening, such as removing more of the wall than a standard patio aperture, also adds cost outside the door itself.

What Keeps the Price Down

A standard two- or three-panel configuration in white or anthracite, on an opening that does not need structural alteration, sits at the more accessible end of the range. Because Slinova is a uPVC system rather than aluminium, it is generally the lower-cost route to a wide sliding door where the brief does not specifically call for an aluminium frame.

Rehau Slinova vs Aluminium Sliding Doors

The comparison homeowners make most often is Slinova against an aluminium slider such as our Cortizo or Schuco ranges. Aluminium generally commands a premium over uPVC for a comparable span, in exchange for slimmer sightlines and, in some configurations, larger single panels. Slinova closes much of that gap while keeping the wide glass and A-rated energy performance that make a sliding door worth choosing over French or bifold doors in the first place. Where the brief is maximum glass for the lowest realistic outlay, Slinova is worth comparing directly against an aluminium quote before deciding.

Installation and What Else Affects the Total

The condition of the opening matters as much as the door itself. A straightforward like-for-like replacement of an existing patio door is more straightforward than a new opening formed in a solid wall, which involves additional building work priced separately from the door. Access to the property, the need for scaffolding or crane assistance on upper floors, and any lead-related or asbestos considerations on an older property can all add to the overall project cost, though these apply to the wider works rather than the door itself.

Getting an Accurate Figure

Because so much depends on your specific opening, glazing choice and finish, the only way to get a number you can rely on is a survey. We measure the opening, confirm the configuration and specification with you, and provide a fixed quote before any work begins, so there are no surprises once the order is placed.

We supply and install the Rehau Slinova sliding door system. Every installation is FENSA registered and carries a 10-year CPA insurance-backed guarantee.

Frequently Asked Questions

Is Rehau Slinova cheaper than aluminium sliding doors?

Generally, yes. Slinova is a uPVC system and typically sits below a comparable aluminium slider for a similar span, though the gap narrows on larger or higher-specification configurations. The only way to compare like for like is a quote for both.

What affects the price of a Slinova sliding door the most?

The number of panels and overall width, the glazing specification, and the colour or finish are the three biggest factors. A wide, multi-panel run in a bespoke colour with upgraded glass sits well above a standard two-panel door in white.

Does forming a new opening cost more than replacing an existing door?

Yes. Replacing an existing patio door like for like is more straightforward than forming a new opening in a solid wall, which involves separate building work priced outside the door itself.

Can I get an exact price without a survey?

Not reliably. Slinova is fabricated to the exact opening, so an accurate figure depends on the actual dimensions, glazing choice and finish confirmed on site rather than a generic estimate.

Does the price include installation?

Our quotes cover full supply and installation, including removal of the existing door where applicable. Any structural work to enlarge or form an opening is scoped and priced separately once confirmed at survey.
