Capital Allowances may be governed by legislation, but in practice, they are shaped just as much by case law. This is where Elect’s expertise sets us apart.

Our approach is rooted in a deep understanding of the judicial principles that define what does and doesn’t qualify as “plant,” from Victorian-era rulings to the most recent tribunal decisions. By grounding our analysis in the same legal reasoning that underpins HMRC’s interpretation, we help clients secure claims that are not only maximised but also technically robust and fully defensible. In a landscape where the smallest distinctions can unlock significant tax savings, Elect turns complex precedent into a clear commercial advantage.

When most discussions about Capital Allowances reach back to Yarmouth v France (1887), it’s often treated as a foundational case. But here’s the interesting truth: it wasn’t a Capital Allowances case at all.

The case originally concerned an employer’s liability for an employee’s injury, and whether a horse used in the business could be considered “plant”. The Court of Appeal’s landmark definition stated that “plant” includes: “Whatever apparatus is used by a businessman for carrying on his business, not his stock-in-trade.”

Though this ruling predated Capital Allowances legislation by decades, it established the conceptual line that underpins every modern claim:

• Plant and machinery – eligible for Capital Allowances

• Stock-in-trade or setting – not eligible

In other words, Yarmouth v France created the intellectual foundation for how we still distinguish functional business assets from their premises today.

How the Yarmouth Principle Evolved

Subsequent decades of case law have refined what qualifies as “plant”, but all trace their logic back to Yarmouth v France. Some of the key milestones include:

IRC v Barclay, Curle & Co Ltd (1969): Confirmed that even structural fixtures, such as those in a dock, could be “plant” if they served an operational purpose.

Wimpy International Ltd v Warland (1988): Showed that restaurant fit-outs could qualify for allowances where they helped the business function, not just form part of the premises.

Scottish & Newcastle Breweries Ltd v Raggett (1982): Explored where to draw the line between plant and building elements within hospitality properties.

May & Anor (t/a Pegasus Birds) v HMRC (2019): A modern example of how fact-sensitive Capital Allowances remain — especially regarding an asset’s purpose and permanence.

These cases and the legislation they’ve shaped demonstrate how a 19th-century judgment still drives real financial outcomes for today’s property owners and investors.
