- Windows supplied and fitted are at the 13.5% VAT rate (Revenue). Ask whether the written price includes it.
How this is worked out
The number of windows you pick, times Expert Windows & Doors' published installed price a window for that frame. BuildTech's published price a window is shown next to it where it gives one. The multiplication is ours. Prices read on 3 November 2026. Neither page says whether VAT is in. Size counts: a big picture window or a bay costs more than a small bathroom window, and doors are extra. It's an estimate, never a quote.

SEAI's medians are the costs registered contractors submitted when the grant was paid: the mid-point of real jobs, not a list price. The firms' ranges are their own, and wide, because a house can have 6 windows or 16. Selectra.ie's range is for an average 3-bed semi.

FAQ
Questions people ask
Why do window prices vary so much?
The number and size of windows, the frame, the colour, double or triple glazing, the opening type, and how much making good is needed. Ten white casements and ten grey sashes are different jobs.
What's the average cost of new windows for a 3-bed semi?
SEAI's median for a semi-D or end of terrace was €7,110, January to June 2026. Firms publish €4,500 to €10,000+ (Expert Windows & Doors) and €4,500 to €8,500 in uPVC (BuildTech).
Is it 13.5% or 23% VAT on new windows?
Windows are fixtures, so supply and fitting is at the reduced rate, 13.5% (Revenue, Dáil answer). Windows bought supply-only are a sale of goods at the standard rate.
Is it cheaper to do a few windows at a time?
A window costs less a unit on a whole-house job, because the survey, the van and the crew are shared. Doing the worst side first is fine if the budget needs it.
