VAT on extensions: 13.5% or 23%?
Building work on a house in Ireland is charged VAT at 13.5%. A fitted kitchen supplied and fitted as part of the job is usually 13.5% too, because built-in units are fixtures. Appliances like ovens, hobs and dishwashers are fittings, so they're at 23%. Every price on this site includes VAT.

Which rate applies to what
| Item | VAT |
|---|---|
| Building the extension (construction services) | 13.5% |
| Windows, doors and rooflights, supplied and fitted | 13.5% |
| Kitchen units and worktops, built in, supplied and fitted | 13.5%, subject to the two-thirds rule |
| Cooker, hob, oven, dishwasher, washing machine | 23% |
| Professional fees (architect, engineer, BER) | 23% |
The two VAT rates are 23% and 13.5% (Revenue). Revenue's guidance on fixtures and fittings lists built-in units, kitchen units and counters included, as fixtures: supplied and installed, they're work on the building and take the reduced rate, subject to the two-thirds rule. Appliances are fittings: movable goods at the standard rate.
The two-thirds rule
Where a job is mostly goods, the goods rate can apply to the whole thing. If the value of the goods is more than two-thirds of the price of a supply-and-fit job, the whole job is charged at the goods' rate. On an extension, the building work dwarfs the materials, so it's 13.5%. On a kitchen supplied and fitted on its own, it's worth asking how your supplier applies it.
Getting VAT right on a quote
- Ask whether each price includes VAT, and at which rate.
- A builder registered for VAT shows their VAT number on the invoice.
- A price "plus VAT" on a €60,000 build is €8,100 more at 13.5%.
- Fees are VAT-able at 23% if the professional is VAT-registered.

A 25 m² single-storey rear extension in Ireland, mid-range, with wide glass doors and a new kitchen: €62,000 to €90,000 all in, including VAT and fees.
How this is worked out
We start from what single-storey extensions cost to build per square metre in each part of Ireland, including VAT at 13.5%, and the rates for side, wraparound, two-storey and heavily glazed extensions. Standard finishes take the lower half of the range, mid-range the upper half, and high spec or a wall of glass the glazed rate. Then we add professional fees (design, engineer, BER) and, if you want one, a new kitchen at your level of finish. Totals are rounded to the nearest €1,000. It's an estimate to plan with, never a quote: the builder prices your house after seeing it.
