How the Next Tax Year May Affect 2026 Land Rent Payments

The end of the tax year is a pivotal time for landowners, as it influences income, expenses and long-term planning. For those leasing land to renewable energy operators, the tax cycle also includes additional considerations.

Each April, when thresholds are reset and new fiscal policies take effect, the land rent payments you’ll keep from your rent agreements may change. And this is because rent payments from wind, solar and storage projects are not set in stone. They’re tied to wider economic forces like inflation, government budgets and energy market reforms.

The 2025/26 tax year is shaping up to be particularly important for landowners. After years of frozen tax thresholds and incremental policy adjustments, landowners are now facing a combination of fiscal drag (where inflation and earnings growth push taxpayers into a higher tax bracket), higher operating costs for developers, and renewed scrutiny of inheritance and property reliefs.

At the same time, the energy landscape is shifting quickly. Ofgem has cleared out stalled grid projects, new government support has been introduced for long-duration storage, and demand for land that can host renewables and battery storage infrastructure is only increasing.

These changes come at the same time as tax deadlines. So, the coming year could reshape both the income you receive and the tax you ultimately pay. For many landowners, the challenge lies not just in negotiating rent, but keeping your agreements tax-efficient.

In this article, I’ll explore:

• The main changes to land rent payments that landowners need to look out for as we head toward 2026
• What these mean for minimum and turnover rents
• How proactive negotiation can help secure a stronger position before the tax year closes

Let’s get started.

Minimum Rent vs. Turnover Rent: A Refresher

Most land rent contracts in the renewable sector are based on two complementary models. Minimum rent is a fixed fee, usually index-linked, that provides a predictable baseline income.

Turnover rent is calculated as a percentage of revenues from power generated and sold.

The balance between the two depends on inflation, energy prices and project performance.

With recent changes to taxation and market conditions, both of these rent structures could behave differently in 2026 than they have in previous years.

The 2025 Budget Landscape and Its Implications for Landowners

Frozen income tax thresholds

One of the most significant developments shaping 2026 is frozen income tax thresholds.

The personal allowance remains at £12,570 for 2025/26, and the higher-rate tax threshold is at £50,270. This means that many landowners may find themselves paying the 40 per cent tax rate simply because rents and other income rise, while the thresholds don’t.

This kind of scenario (known as fiscal drag) quietly increases the effective tax burden year on year, reducing the net benefit of rent increases.

Employers’ National Insurance contributions

Meanwhile, employers’ National Insurance contributions have risen to 15 per cent in 2025/26.

Although landowners themselves may not pay this directly, the change increases costs for developers and operators managing renewable projects. These higher employment costs often cascade through to operating expenses, potentially influencing the turnover rent operators are willing to share.

Late interest payments

On top of that, HMRC has raised late payment interest charges to the Bank of England base rate plus four per cent.

For landowners reliant on timely rent payments to manage tax bills, any delay could now translate to more expensive penalties.

Capital Gains Tax and Inheritance Tax Reforms

Capital Gains Tax (CGT) has also shifted following increases announced in 2024. While not all landowners will be impacted immediately, those selling land or restructuring ownership around energy projects need to model these costs carefully.

Additionally, speculation continues around inheritance tax reforms. Agricultural Property Relief (APR) and Business Property Relief (BPR) are under review, with reforms expected to take effect from April 2026.

This could have major implications for rural estates where land is leased for renewable projects. Currently, APR has been extended to land under qualifying environmental agreements, which is positive, but there are signs that tighter caps or thresholds could apply in future budgets. It also raises further questions about how land-based income and asset value will be treated in succession planning.

All of this highlights the importance of not just chasing headline rent figures, but ensuring agreements are naturally tax efficient. Some landowners are exploring whether to receive income through partnerships, corporate structures or diversified investment vehicles to mitigate fiscal drag.

Grid and Energy Market Changes

Taxation isn’t the only force at play for landowners in 2026 and beyond. Ofgem’s reforms to the grid connection process have prioritised viable projects and cleared out speculative ‘zombie’ developments.

For landowners with sites capable of connecting sooner, this creates stronger negotiating leverage. Demand for land is no longer limited to wind and solar. Battery storage, long-duration energy storage (LDES) and even hydrogen infrastructure are increasingly sought after.

In 2025, the government launched a new cap-and-floor scheme for LDES, creating stable revenue streams for storage developers. Landowners positioned to host such projects could benefit from adding new revenue lines to existing agreements.

Contracts for Difference (CfD) continue to underpin renewable investment, with Allocation Round 7 confirming adjustments to strike prices and capacity budgets. This mechanism gives developers more predictable revenues but also means landowners must understand how CfD terms influence the operator’s appetite to share turnover rents.

If the subsidy margins are squeezed in the new tax year, operators may look to renegotiate terms or push back on higher turnover rent shares.

What All This Means for Rent Negotiations

Minimum rent agreements

For minimum rents, indexation remains the key driver of change.

Most agreements are linked to the Consumer Prices Index (CPI), which is expected to hold steady at around two to three per cent in 2026.

In practice, this means most landowners will see modest uplifts that are enough to offset some cost-of-living increases, but not the windfall rises they might have experienced during periods of higher inflation.

If your contract contains collars and caps

It’s also important to look closely at the fine print on any land rent payments. Some contracts contain collars and caps that limit how much the minimum rent can increase each year.

If your agreement caps annual rises at, say, two per cent, your rent may remain static even if inflation moves higher. This means your real income value could decline over time.

On the other hand, if inflation undershoots expectations, a floor or collar may prevent your rent from falling and give you a degree of protection. Knowing how these mechanisms work (and testing them under different inflation scenarios) is crucial before entering any renegotiation.

Turnover rent agreements

For turnover rents, the dynamics are more complex. Power prices aren’t spiking at the extremes we saw during the energy crisis, and have stabilised at levels that are more predictable but also less inflated.

On the upside, Ofgem’s reforms to grid connections are improving utilisation rates, meaning turbines and solar arrays are generating and exporting more consistently.

This may smooth turnover rents and create fewer peaks and fewer troughs. But stability doesn’t always translate into higher returns. For some landowners, this may actually mean lower year-on-year uplifts if headline power prices are flatter.

This changing environment offers a strong argument for revisiting turnover rent percentages or even shifting to hybrid models. These hybrids may help landowners benefit from baseline security without losing out if revenue growth accelerates.

Strategically valuable sites offer negotiating leverage

It’s also worth noting that landowners who hold strategically valuable sites retain leverage. Locations with existing or near-term grid connection rights, good wind or solar resources, or potential for co-located storage are at a premium.

In these cases, developers may be more willing to concede stronger rent terms, add storage uplifts or agree to inflation-linked hybrid models.

Review clauses in rental agreements

Finally, landowners should recognise that negotiation is no longer a one-off exercise at contract renewal. The evolving tax and policy environment means agreements struck today could look outdated in just a few years.

Building in review clauses (like scheduled reassessments tied to new budgets or major policy shifts) allows landowners to adapt without waiting for full contract expiry. This should keep rent agreements resilient, tax-efficient and aligned with a rapidly shifting landscape.

Practical Steps for Landowners Ahead of 2026

Final Takeaway: Preparation Is Key for Land Rent Payments

The 2025 Autumn Budget will almost certainly bring further considerations for landowners, particularly around inheritance tax and capital gains.

By early 2026, landowners will need to weigh not just how much they’re earning from land rent payments, but how tax-efficient that income is and whether their agreements leave room to adapt.

Proactive renegotiation is becoming increasingly valuable. Rather than waiting for contracts to roll over, landowners should approach operators armed with market data, tax forecasts and a clear sense of their long-term succession goals.
