How Much Does Secondary Glazing Cost in the UK?
The cost of secondary glazing depends mainly on window size, frame style, and the level of noise or thermal insulation you want to achieve, and smaller panes can cost significantly less.
To help you plan your project, our Gecko Panes pricing starts at just £24 per pane, with custom-cut sizes to suit every space. Compared to double glazing costs which often reach several thousand pounds for a three-bed home, secondary glazing offers genuine value and measurable comfort for a much smaller investment.

Why Choose Secondary Glazing Over Double Glazing?
Traditional double glazing can cost anywhere from £3,000 to £15,000+ for a full house, it varies majorly depending on the property size and window materials. It’s also not always suitable for listed buildings, period homes, or properties with original timber frames where the character and appearance must be preserved.
This where secondary glazing is an affordable alternative as it adds a discreet internal panel behind your existing window, creating a sealed air gap that dramatically improves insulation. There’s no need for building work, no risk to your existing windows, and the results are instant.
At Gecko Glazing, our innovative Gecko Panes provide the same warmth, quiet, and energy efficiency you’d expect from high-end glazing, but without the disruption or cost of full replacements. They can also be up to 80% more affordable than regular double glazing.
Our product, Gecko Panes, combines crystal-clear 2mm acrylic with a precision-cut 6mm aluminium frame. Each pane fits neatly into place using a soft, sponge-like seal that forms a secure, draught-proof barrier.
They’re lightweight, easy to install, and completely removable, ideal for listed buildings or rental homes where you can’t alter the original windows. Every pane is made to order for a perfect fit.

Why Choose Secondary Glazing Over Double Glazing?
Installing new double glazing can cost thousands per property, and that’s before considering plastering, redecorating, or disposal of old frames. Secondary glazing offers a smarter route: minimal disruption, immediate savings, and insulation performance that rivals replacement windows.
With Gecko Panes, you can expect to cut heat loss by up to 50%, which quickly offsets the initial secondary glazing cost through reduced energy bills. Customers often may also see payback within a single heating season, making it not only an affordable upgrade but a genuinely efficient one.
