On 27 October 2026, the day before the Autumn Budget, the Treasury told British farmers some good news. From 26 November, tariffs of 2% to 6.5% on selected imported fertilisers will be removed. Defra Secretary Dame Angela Eagle said it would give farm businesses "more room to breathe".

Within hours, the NFU poured cold water on it. President Tom Bradshaw said the cut was "unlikely to make a meaningful difference" to farm businesses.

So who is right? Here is the short answer. The tariff cut is real, but it is small, it may not reach your invoice, and it changes nothing about the real problem: your biggest costs are set by people you will never meet. The farms that sleep well this winter are building income that never needs a bag of urea.

The short answer: At today's prices, the most a 6.5% tariff cut can take off a tonne of urea is about £29, and only if your merchant passes all of it on. In March 2026 alone, urea jumped £163 a tonne. Don't plan your farm around the tariff cut. Plan around income you set the price for: visitors, farm shop sales, pick-your-own, stays and events.

Flowchart showing five ways a UK fertiliser tariff cut can leak before it reaches a farmer's invoice — The five leaks between a Treasury announcement and your fertiliser invoice.

What the Treasury actually announced

The cut is part of a wider package that removes tariffs on more than 100 products. Kerosene heating oil loses its 4% tariff too. Here is what we know, and what we don't, as of 28 October 2026.

Question	What we know
How big is the cut?	Tariffs of 2% to 6.5% on selected fertilisers
When does it start?	26 November 2026
Which products?	Not confirmed. The May 2026 consultation named urea, ammonium sulphate, DAP, MAP and compound fertilisers
Is UAN included?	UAN's 6% tariff was already suspended from 5 August 2026 to 31 December 2028
How long will it last?	Not confirmed. The consultation proposed a one-year suspension

Notice the gap. Nobody has yet published the final product list. And ammonium nitrate, the single most-used fertiliser in Great Britain at about 35% of fertiliser tonnage in 2023, was not on the consultation list.

Why the NFU says "don't bank on it"

Bradshaw gave three reasons, and each one is a leak in the pipe between the Treasury and your farm gate.

First, much imported fertiliser already arrives in the UK tariff-free. A cut on a tax you were not paying saves you nothing.

Second, the saving depends on whether the products covered are the ones UK farmers actually buy. If you mainly spread AN, a cut on DAP does little for you.

Third, the saving depends on whether importers and merchants pass it down the supply chain. Importers, distributors and merchants all sit between the port and your yard.

Then come two bigger leaks. On 1 January 2027 the UK's carbon border tax, CBAM, starts charging on imported fertiliser. By Farmers Weekly's sums, HMRC's illustrative first-year rate works out at about £3.77 a tonne of ammonium nitrate, yet the same paper has also reported CBAM could add 6-7% to prices. Those two estimates are far apart, so watch this space. And gas is still king. AHDB says gas makes up about 60% of the cost of making nitrogen fertiliser.

Reality Check: A tariff cut is a one-off change. Gas prices and carbon taxes move every month. If your margin depends on fertiliser getting cheaper, your margin depends on gas prices and the Middle East.

Do the maths: what 6.5% is really worth

Let's put real numbers on it. AHDB's price for granular urea in mid-October 2026 was £480 a tonne.

If a 6.5% tariff is fully baked into that price, removing it saves £480 minus £480 ÷ 1.065, which is about £29 a tonne. That is the best case. Tariffs are charged on the import value at the port, not the delivered price, so the real saving will be lower.

Example	Best-case saving
One tonne of urea at £480	About £29
One hectare of wheat at a typical recent 170 kg N, all as urea (about 0.37 t)	About £11
200 hectares of wheat	About £2,200 a year

Now compare that with what the market did on its own.

Bar chart comparing the most a 6.5% fertiliser tariff cut can save on urea, £29 a tonne, with a £91 a tonne yearly rise in ammonium nitrate and a £163 a tonne one-month rise in urea — One bad month in March 2026 wiped out more than five years of best-case tariff savings.

Between February and March 2026, as conflict in the Middle East hit gas supplies, urea rose from £455 to £618 a tonne. That is a £163 jump in roughly a month. UK-made ammonium nitrate is up £91 a tonne on a year earlier.

Line chart of UK-produced ammonium nitrate prices from £393 a tonne in September 2025 to £504 in March 2026 and £485 in October 2026, against a 2020 average of £217 — UK ammonium nitrate is still more than double its 2020 average.

The number that should keep every arable farmer awake

Defra's own figures tell the real story. In 2024/25, the average English cereal farm made £49,700 of farm business income. But the farming itself lost £27,400.

Bar chart of average English cereal farm income in 2024/25: farming lost £27,400, diversification earned £32,600, agri-environment £25,900, Basic Payment £18,600, total £49,700 — On the average cereal farm, diversification was the biggest single source of income, while the farming itself lost money.

The biggest positive part of that income was diversification, at £32,600. Across all farm types in England, 72% of farms now have some diversified activity.

And the Basic Payment is shrinking fast. It fell from 55% of farm business income in 2020/21 to 19% in 2024/25. Defra forecasts average cereal farm income will fall by about two-thirds in 2025/26, to around £17,000. The NFU says that would be the lowest since records began in 2004/05.

In other words, the tariff cut is a sticking plaster. The wound is a business model where you buy at world prices and sell at world prices. We explored the same trap in The $8 Billion Fuel Bailout Won't Save Your Farm and Why the Smartest Farmers Never Let a Government Cheque Be the Plan.

The farm income that never needs a bag of urea

A family picking pumpkins does not care what urea cost in March. A couple booking a farm stay does not check the AHDB price page. When you sell an experience, you set the price.

Here are three real British farms that made this shift.

Smeaton Farm, Cornwall. Ashley Jones farms 360 hectares, yet one 8-hectare field now brings in more than half the farm's business income. When his parents took on the tenancy in 2006, they restarted an old maize maze on that field. Today it hosts pick-your-own tulips, a sunflower maze and a pumpkin patch, and the farmhouse runs a B&B. As the farm puts it: "We always try to add something new each year."

Tulleys Farm, West Sussex. The Beare family arrived in 1937, when it was a small dairy farm, then grew salad and pickling crops. They added pick-your-own in the 1970s and opened a farm shop in 1992. For their 2024 Tulip Festival they expected about 12,000 visitors. Nearly 95,000 came.

Boston Park Farm, Doncaster. Two brothers farmed 600 acres between them, but once one retired, the land left could not pay for the machinery. In 2000 the family opened what they say was Yorkshire's first maize maze. Today the farm has a visitor centre, animals, educational farm groups and a Santa's grotto, drawing nearly 100,000 visitors a year.

Field-Tested Play: Pick your one "8-hectare field". It is usually the field nearest the road with the easiest parking. Ask: what could families do here for a ticket price? A pumpkin patch, a maze or a flower field are proven starters. See How to Start a Pumpkin Patch, How to Start a Corn Maze and How to Start a U-Pick Flower Field.

The demand is there. Airbnb reported UK farm-stay bookings up 14% for summer 2026, with Gen Z bookings up 41%. In Scotland, agritourism and farm retail are already worth £292.9 million, beating the 2030 target four years early.

What we learned on our own farm

At Bloopy Durians, our farm in Bentong, Malaysia, the durian season only runs about four to five months a year. We cannot control the weather or the wholesale price.

What we can control is the visitor. People come from all over the world to eat durians under the trees, and many companies send their staff and management to the farm. We also keep a WhatsApp list of loyal customers who buy whenever the fruit is ready. That list is the most reliable income we have, and no tariff, gas price or carbon tax can touch it.

Paperwork: questions to ask before you open the gate

This is not legal advice. These are the questions to put to your planning officer, accountant and insurer in England. Rules differ in Wales, Scotland and Northern Ireland.

Can I use the 28-day rule? Land (not buildings) can be used for most temporary purposes for up to 28 days a year without planning permission, with markets capped at 14 of those days. Camping is excluded.
Can I run a pop-up campsite? England allows up to 60 days a year and 50 pitches, with written notice to the council each year and on-site toilets and waste disposal. Flood-risk land needs prior approval.
Can I convert a barn? Class R permitted development lets some farm buildings change to commercial uses, up to 1,000 square metres.
Will I pay business rates? Farm buildings are exempt only while used for farming. A shop or venue usually becomes rateable, though small business rate relief can cut the bill to zero.
Am I insured? Employers' liability is compulsory once you employ staff, unless they are all close family. Public liability is essential once the public walks onto your land. See Agritourism Insurance: What It Covers and What It Costs.

Reality Check: If visitors touch animals, follow HSE's advice: running water, soap and paper towels, because gels and wipes are not a substitute. Our guide on petting zoo handwashing shows how.

Frequently asked questions

When does the UK fertiliser tariff cut start?

The Treasury says the cut takes effect on 26 November 2026. It removes tariffs of 2% to 6.5% on selected fertiliser products.

Which fertilisers are covered by the tariff cut?

The final list had not been published as of 28 October 2026. The May 2026 consultation named urea, ammonium sulphate, DAP, MAP and compound fertilisers. UAN's tariff was already suspended separately from August 2026.

How much will the fertiliser tariff cut save me?

At October 2026 prices, the most it can save on urea is about £29 a tonne, and only if suppliers pass it all on. On 200 hectares of wheat that is roughly £2,200 a year at best.

Why does the NFU doubt farmers will see the savings?

The NFU says much fertiliser already comes in tariff-free, the products covered may not be the ones farmers use, and savings may not be passed down the supply chain. It also warns that CBAM from 1 January 2027 could add new costs.

What is CBAM and how will it affect fertiliser prices?

CBAM is the UK's carbon border tax. From 1 January 2027 it charges imported fertiliser for the carbon used to make it. HMRC's illustrative first rate equals about £3.77 a tonne of ammonium nitrate, and it is expected to rise in later years.

What farm diversification makes the most money in the UK?

In England, letting buildings is both the most common and the best-paying diversified income, averaging £27,900 for the farms that do it. For farms ready to welcome visitors, pick-your-own, pumpkin patches, mazes, farm shops and farm stays let you set your own prices. Read Is Agritourism Profitable? for real numbers.
