Daylight Robbery

Walk through Bath, or Edinburgh, or the terraces of any Georgian town in England, and you will see them: windows bricked up from the inside, their outlines still visible in the stone. They are not decorative. They are three hundred year old tax receipts.

In 1696, William III introduced the window tax, a levy on the number of windows in a house. The logic was seductive. Windows were visible. Windows were countable. And the more windows you had, the wealthier you probably were. It was, in the language of its day, a fair proxy for means.

The people of Britain, being people, responded accordingly. They bricked up their windows. Landlords sealed the openings of tenement houses, plunging the poorest into darkness so the wealthiest could minimize exposure. The phrase “daylight robbery” is popularly, if disputably, traced to this period. What is beyond dispute is the outcome: a tax designed to reach the rich fell hardest on those who could not afford to complain.

The tax lasted 155 years before Parliament repealed it in 1851. The bricked up windows remain.

On 20 July 2026, Andy Burnham became the seventh British prime minister in a decade, entering Downing Street with a pledge to make politics “work better,” and promising in the weeks that followed to make taxation “fairer.” Within weeks, his government confirmed plans for the High Value Council Tax Surcharge, a levy already dubbed the mansion tax, to take effect from April 2028 on residential properties valued above two million pounds. Reports suggest Burnham is considering lowering the threshold to one and a half million, which would nearly double the number of properties caught, from roughly 127,000 to 243,000, many of them in the South of England.

The enforcement mechanism has already drawn criticism. HMRC valuation agents, branded the “council tax police” by opponents, are to be dispatched to homes across England to determine whether properties exceed the threshold. Homeowners who refuse entry reportedly face fines for obstruction.

The parallels with 1696 are not incidental. They are structural. When a government taxes a visible proxy for wealth, people find ways to make the proxy invisible. The window tax taught this lesson in bricks and mortar. The mansion tax will teach it again, this time in contested valuations, subdivisions, trusts, and every legal structure a good solicitor can devise. The proxy changes. The response never does.

A friend put the deeper question plainly in a message this week. How is the UK the world’s fifth largest economy when government debt stands at ninety five per cent of GDP, the tax burden is heading to levels the Office for Budget Responsibility calls “uncharted territory,” and the welfare bill exceeds the amount raised from employees in income tax? It is a question millions of Britons are asking.

The answer is that GDP measures output, not health. It tells you how much a country produces, not how wisely it distributes or how sustainably it borrows. The United States sits atop the global table with the largest national debt in human history. Japan’s debt to GDP ratio approaches two hundred and forty per cent. A large economy can service large debts, until it can’t. Britain’s property tax burden, at 3.7 per cent of GDP, is already the highest among major economies. Adding a mansion tax on top of council tax, stamp duty, and inheritance tax does not broaden the base. It thickens the layer.

Israel knows something about this. The municipal property tax, arnona, has been levied on every home and business in the country since the state’s founding. It is calculated not on market value but on floor area, measured in square metres, adjusted for location and use. Two apartments in Tel Aviv worth vastly different sums can carry identical arnona bills because the tax sees area, not price. It is a different proxy, and it produces its own distortions. Homeowners underreport extensions. Municipalities set wildly inconsistent rate bands. But there is a candour in the Israeli system that the British one lacks. In a country where roughly ninety three per cent of land is state owned through the Israel Land Authority, there is no pretence that property exists outside the reach of the sovereign. The state leases the ground and taxes the structure. The relationship is transparent, if not always comfortable.

Britain, by contrast, layers tax upon tax while maintaining the fiction that an Englishman’s home is his castle. Council tax is based on valuations from 1991, more than three decades out of date. Stamp duty punishes mobility. Inheritance tax punishes death. The mansion tax will punish size. Each levy arrives with its own logic and its own loopholes, and none addresses the underlying question that Israel, for all its imperfections, at least asks openly: what is the relationship between the citizen, the land, and the state?

The window tax ran for 155 years. In all that time, no government revisited the original assumption. It simply taxed the light and left people to find their darkness.

In the Georgian terraces of Bath, the rooms behind those bricked up windows are still dark. The tax was repealed in 1851. The light never came back. Burnham, the seventh prime minister in ten years to promise a fairer settlement, might reflect on that. Fiscal scars outlast the policies that caused them. The room was emptied of its light three centuries ago. No one has yet thought to open the window.
