The Telegraph this week published a column arguing that solar farms are ‘carpeting our prime farmland with pointless panels’, a claim that has reignited the land-use debate in the UK. For homeowners weighing solar panels on their own roofs, the noise around farmland can be confusing. Does a solar installation on your house somehow compete with wheat fields? The short answer is no, but the longer answer matters for anyone thinking about their energy bills, EPC rating, or carbon footprint.
As reported by The Telegraph, the piece argues that solar developments are encroaching on Grade 1 and 2 agricultural land, the best soil in the country. Yet the data tells a different story. According to the Department for Environment, Food and Rural Affairs, less than 0.1% of UK farmland is currently used for solar panels. The vast majority of solar farms sit on Grade 3b, 4, or 5 land, land that is marginal, poor-quality, or already degraded.
What the land-use debate misses
The real tension is not between solar and food, it is between solar and housing. The UK needs 300,000 new homes a year, many on greenfield land. Solar farms, by contrast, are temporary. Most have 25-year leases, after which the land can be returned to agriculture. The National Farmers Union itself supports solar on non-prime land, provided it does not displace food production. The catch is that planning permission for solar farms is often easier to get on lower-grade land, but developers sometimes target better land because it is flatter and closer to grid connections. That is a planning failure, not a technology failure.
For the average homeowner, the farmland debate is a distraction. The Energy Saving Trust estimates that a typical 3.5 kWp rooftop solar system on a semi-detached house in the south of England can save £200–£300 a year on electricity bills. With the Smart Export Guarantee, households can also sell surplus power back to the grid at around 5–6p per kWh. That is a direct financial return, no land required.
EPC impact and the net-zero target
Installing solar panels can improve a home’s Energy Performance Certificate rating by up to two bands, from D to B in some cases, depending on existing insulation and heating. That matters because from 2025, landlords will need a minimum EPC rating of C for new tenancies, and the government is consulting on extending similar requirements to owner-occupied homes by 2035. Solar alone won’t get you there if your walls are uninsulated and your boiler is 20 years old, but it is one of the most cost-effective single upgrades.
The UK has a legally binding target to decarbonise electricity by 2035. The Climate Change Committee says we need 70 GW of solar capacity by then, up from 15 GW today. Rooftop solar could deliver 40 GW of that, but current installation rates are too slow. The government’s recent relaxation of permitted development rights for rooftop panels on homes and commercial buildings is a step in the right direction, but more needs to be done to cut red tape and reduce upfront costs.
What homeowners should do now
If you are considering solar, the first step is to check your roof’s orientation, shading, and structural integrity. South-facing roofs with no shading are ideal, but east-west arrays can also work well. The average cost of a 4 kWp system is around £5,000–£7,000, though prices have fallen 70% in the last decade. The Boiler Upgrade Scheme does not cover solar, but the Smart Export Guarantee and VAT relief (0% on installations until 2027) help.
For homeowners with land, a large garden or field, ground-mounted solar arrays are an option, but they require planning permission if over 9 m² or if they face a highway. Again, the principle is the same: put panels where they don’t compete with food production. A 4 kW ground array might cost £8,000–£12,000 and generate 3,500–4,500 kWh per year, enough to cover a typical household’s electricity use.
The farmland debate is real, but it should not stop homeowners from doing what is sensible: putting solar on roofs, not on wheat fields. The government should prioritise rooftop deployment and ensure that any new solar farms on agricultural land are on the worst land, not the best. That is the way to keep food on the table and power in the grid.
Frequently Asked Questions
Very little. Less than 0.1% of UK farmland is used for solar, and most is on poor-quality land. The impact on food production is minimal, and after 25 years the land can return to agriculture.
Yes. Rooftop solar uses existing built space, avoids land-use conflicts, and directly cuts your energy bills. It also improves your EPC rating, which is becoming more important for property value and rental rules.
