Why UK Farmers Shouldn't Be Renting Their Energy in 2026

The 1,000+ view question

UK farmers paying grid prices are renting their energy. They pay every month, the cost goes up every year, and at the end of any given decade they've spent six figures with nothing to show for it. KMM's "renting energy" video lays out the case in 112 seconds. This article lays out the full numbers.

The renting maths

A typical UK arable + livestock farm spends around £35,000/year on electricity in 2026. Across 25 years — the warranted life of a tier-1 solar PV system — that compounds at conservative 4% annual electricity inflation to:

That £1.46m is the rent. None of it builds equity. None of it hedges. At the end of year 25, the farmer has the same bill, just larger.

The ownership maths

The same farmer installing a 150 kWp solar + 60 kWh battery system in 2026 spends around £180,000 gross (before tax and grants), nets to about £110,000 after a farm capital grant and AIA tax relief. The system displaces around 75% of their grid use in year 1 and 65-80% across its 25-year life as load shifts. Total displaced grid spend:

The flip

Renting: -£1,455,000 over 25 years.
Owning: +£900,000 over 25 years.
Total swing: £2,355,000 in the ownership column.

This isn't a wild-eyed projection. It's a 75% self-consumption assumption, 4% conservative electricity inflation (well below the 9.2% UK average from 2010-2025), and standard tier-1 hardware lifetime. It also doesn't include diesel-displacement savings (typical £2,000-£4,000/year on mixed-arable farms with grain dryers or irrigation pumps).

The objection most farmers have

"I don't have £110,000 to spend." Three answers:

• PPA — third-party funds the install, you pay only for the kWh consumed at a tariff well below grid. Zero upfront, 7-13p/kWh tariff fixed for years 1-10.
• Asset finance / lease — 5-10 year fixed monthly, net-positive cashflow from year 1.
• Grant + CAPEX — Lincolnshire Rural Business Grant covers up to £40,000; the remainder finances or you pay from cash with Annual Investment Allowance (AIA) tax saving in year 1.

The cost of doing nothing is now £58,200/year (£1.46m / 25). That's the rent you're paying every month to keep the same setup. Solar PV is the cheapest hedge against energy-price volatility currently available to UK farms. See the farm solar page or request a fully funded survey.
