How to Plan Agricultural Oil Purchases Throughout the Year

Fuel purchasing is one of those jobs on a farm that can easily become reactive. The tank gets low, machinery needs to go back into the field, and an order has to be placed quickly.

That approach may work occasionally, but it is not an efficient way to manage agricultural fuel over an entire year.

For farms that rely heavily on tractors, combines, telehandlers, generators, grain-drying equipment and other fuel-dependent machinery, purchasing decisions need to reflect the way the business actually operates. Demand changes with the season, the workload, weather conditions and the type of farming being carried out.

A well-planned approach to agricultural oil purchases gives farmers greater control over fuel availability, expenditure and operational risk. It also makes it easier to prepare for periods when fuel consumption can increase significantly.

The objective is not to predict the exact day when fuel prices will be at their lowest. It is to make sure the right quantity of fuel is available when the farm needs it, without unnecessarily tying up money in excess stock.

Understand Your Farm's Agricultural Oil Requirements

Before deciding when to purchase fuel, establish how much the business actually uses.

Previous purchase records are a good starting point. Ideally, look at two or three years rather than relying on a single year's figures. One farming season can be unusual because of weather, crop changes, machinery breakdowns or changes in the amount of work undertaken.

Look at total litres purchased and identify when those litres were used.

For example, an arable farm may see considerably higher consumption during cultivation, drilling and harvest. A livestock farm may have a more consistent requirement, while an agricultural contractor can experience large fluctuations depending on the amount of work booked.

This historical information creates a useful baseline.

However, it should not simply be copied into the next year's budget.

Consider what has changed.

Have you increased your acreage? Have you purchased different machinery? Are you undertaking more contracting work? Have cultivation practices changed? Is there a new grain dryer or generator on the farm?

Every one of these factors can alter the amount of agricultural fuel required.

Look at Fuel Demand Rather Than Simply Looking at the Calendar

A common mistake is to divide annual fuel consumption equally between twelve months.

Farming does not work that way.

A farm might use relatively little fuel during a quiet period and then consume a substantial amount in a few weeks when field operations intensify.

Instead of creating an equal monthly allowance, identify the activities that drive fuel consumption.

Spring cultivation, drilling, spraying, mowing, silage work, harvesting, grain drying and autumn cultivation can all create different demand patterns.

This is particularly important when planning for harvest.

The question is not simply how many litres the farm used last year. The more useful question is:

How many litres could the farm need during its busiest operating period this year?

That figure has a direct impact on when fuel should be ordered and how much stock should be available.

Create a Baseline From Previous Agricultural Fuel Consumption

Historical consumption provides evidence rather than guesswork.

Review previous invoices, tank records and machinery records where available. Look for recurring patterns and unusual spikes.

You may discover, for example, that fuel consumption rises sharply during a particular cultivation period or that the farm regularly needs additional deliveries during harvest.

Those patterns are valuable because they show where the existing purchasing strategy is working and where it needs improvement.

It is also worth recording emergency purchases separately.

If the farm has repeatedly had to arrange urgent fuel deliveries, do not simply regard those orders as unavoidable. Ask why they happened.

Perhaps the forecast was too low. Perhaps consumption increased because of poor weather. Perhaps delivery times were longer than expected.

Each emergency order provides information that can improve the next purchasing cycle.

Forecast the Coming Year Based on What Has Changed

Once the historical baseline is established, adjust it for the year ahead.

A simple forecast might begin with previous consumption and then account for known changes.

These could include:

• Changes in cultivated acreage
• Different crops
• New or replaced machinery
• Additional contracting work
• Changes in cultivation methods
• Increased irrigation
• Changes to livestock operations
• Additional drying requirements
• Generator usage
• Expected changes in working hours

For example, if the farm has added another 200 hectares of contracting work, last year's fuel consumption is unlikely to provide an accurate forecast.

Likewise, if machinery has been replaced with newer equipment that changes fuel consumption, historical figures should be treated as a starting point rather than a final answer.

Plan Agricultural Oil Purchases Around Peak Workloads

Fuel procurement becomes particularly important before high-demand periods.

A farm should know approximately how much fuel will be required before entering a period of intensive work.

Harvest is the obvious example.

Consider the expected operating time of combines, tractors, grain carts, telehandlers and other equipment. Then consider additional fuel requirements associated with grain handling and drying where applicable.

Weather also needs to be considered.

A dry, straightforward harvest may finish quickly. A difficult season can stretch operations and increase machinery hours.

This is why a sensible contingency allowance can be more valuable than attempting to predict the exact fuel price several months ahead.

Establish a Practical Reorder Level

One of the simplest ways to improve agricultural fuel management is to decide in advance when the next order should be placed.

Waiting until the tank is almost empty creates unnecessary pressure.

Instead, establish a reorder level based on the farm's normal consumption and supplier delivery times.

For example, if a farm can consume a substantial amount of fuel during a busy week, the reorder point should provide enough stock to cover expected usage while allowing sufficient time for the next delivery.

The figure will be different for every farm.

A business using relatively small quantities throughout the year does not have the same requirements as a large arable operation entering harvest.

The important principle is that the reorder decision should be made before the farm reaches a critical stock level.

Consider Storage Capacity Before Buying in Bulk

Buying a larger quantity of fuel can sometimes be commercially attractive, but storage capacity needs to be considered first.

A farm should know:

• How much fuel the tank can safely hold
• How much usable capacity remains
• Whether the storage installation is suitable
• Whether the tank and equipment are maintained properly
• How much working capital will be tied up
• How quickly the fuel is expected to be consumed

Maximum storage capacity and ideal stock level are not necessarily the same thing.

Holding more fuel than the farm can realistically use in a reasonable period may provide little additional benefit.

Storage requirements and environmental responsibilities should also be considered alongside the purchasing decision, particularly for larger agricultural fuel installations.

Compare Agricultural Oil Suppliers on More Than Price

Price is naturally important, but it should not be the only consideration.

When comparing agricultural oil suppliers, look at the complete purchasing arrangement.

Consider the quoted price, delivery charges, minimum order quantity, expected delivery time and payment terms.

Most importantly, consider reliability.

A supplier offering a slightly lower price may not represent the best overall value if the farm cannot obtain fuel when it needs it.

This becomes especially important during periods of high agricultural demand.

For a farm, the cost of machinery standing idle because fuel has not arrived can quickly outweigh a small difference in the price per litre.

Use Delivered Cost When Comparing Fuel Quotes

Fuel prices should be compared on a like-for-like basis.

The figure that matters to the farm is the cost of getting the required fuel into its storage tank.

When comparing quotations, consider:

Fuel price + applicable delivery costs = delivered purchasing cost

Also make sure the quotations relate to the same fuel type, quantity and commercial terms.

This prevents a low headline price from appearing attractive when additional charges make the final cost considerably different.

Keeping a simple record of previous quotations can also show how supplier pricing changes over time.

Keep Harvest Fuel Separate From Normal Farm Consumption

Harvest deserves its own section in the annual fuel plan.

For many arable businesses, it represents one of the most demanding periods of the year.

Estimate the expected fuel requirement for the main machinery involved and then consider additional requirements such as grain drying.

Do not rely entirely on an annual average.

A farm could have enough fuel on paper for the year but still run short during harvest because too much of the annual requirement is consumed within a concentrated period.

The solution is to plan stock around when fuel is needed, not simply around how much is needed over twelve months.

Monitor Fuel Consumption During the Season

A purchasing plan should not be written once and forgotten.

Check actual consumption against the forecast throughout the year.

If the farm is consuming fuel faster than expected, identify the reason.

It could be:

• More fieldwork
• Poor weather
• Longer machinery operating hours
• Additional contracting work
• Increased drying requirements
• Machinery inefficiency

The earlier the difference is identified, the easier it is to adjust the next purchase.

This is particularly valuable during harvest, when waiting until the tank is low leaves very little room for correcting an inaccurate forecast.

Track Fuel Use by Machine Where Practical

Total farm consumption tells you how much fuel has been used.

Machine-level information can tell you where it has gone.

Where records allow, monitor fuel use for major machines such as tractors and combines.

Useful measures can include litres per operating hour or litres per hectare.

This information can highlight unusual changes in fuel consumption and may reveal maintenance or operating issues.

It can also improve future purchasing forecasts.

If a particular machine consistently uses more fuel than expected, the next annual plan can be based on real operating data rather than an assumption supplied by a manufacturer or an old spreadsheet.

Include Fuel Security in Your Purchasing Plan

Fuel planning is not only about quantity and price.

Security matters as well.

Agricultural fuel is a valuable asset, and larger storage installations need sensible security arrangements.

Consider the location of the tank, access to the dispensing equipment and who is authorised to use the fuel.

Keeping accurate stock records can also help identify unexplained differences between expected and actual tank levels.

A purchasing plan is much more effective when stock records can be trusted.

Consider HVO Within a Long-Term Fuel Strategy

For some agricultural businesses, HVO may form part of a longer-term fuel strategy.

However, changing fuel should never be based solely on environmental claims or price comparisons.

Before using HVO, check whether the machinery is approved for the fuel and whether the intended application is appropriate.

The commercial side should also be considered.

Look at availability, delivered cost, storage arrangements and the applicable UK taxation and fuel-use rules.

For farms considering a gradual transition, it may make sense to evaluate individual applications rather than attempting to change every fuel-consuming machine at once.

Use a Rolling Agricultural Fuel Forecast

A useful fuel plan should change as the farming year develops.

Rather than creating a forecast in January and leaving it untouched, update it periodically.

At a minimum, track:

• Current tank stock
• Expected consumption
• Confirmed deliveries
• Upcoming high-demand activities
• Minimum stock level
• Expected expenditure
• Any changes to the original farming plan

This creates a rolling view of fuel requirements.

It also means that a change in the farming operation can be reflected in purchasing decisions before it becomes a supply problem.

Think in Terms of Fuel Risk, Not Just Fuel Price

It is tempting to make every purchasing decision around price.

But fuel purchasing has several forms of risk.

There is price risk if the market moves after an order is placed.

There is supply risk if fuel cannot be delivered when required.

There is stock risk if too much money is tied up in stored fuel.

There is operational risk if insufficient fuel disrupts machinery.

A sensible purchasing strategy balances all four.

The best decision is therefore not always the one with the lowest quoted price.

It is the one that gives the farm an appropriate combination of cost control, availability and flexibility.

Review the Plan After the Busy Season

Once the major fuel-consuming period has finished, review what actually happened.

Compare the forecast with reality.

How many litres were expected?

How many were actually used?

When did consumption peak?

Were additional deliveries required?

Did the supplier deliver when expected?

Was too much stock held?

Did the farm ever come close to running out?

These questions turn fuel purchasing into a continuous improvement process.

The information collected this year becomes the starting point for a more accurate plan next year.

A Simple Year-Round Approach to Agricultural Oil Purchases

There is no universal purchasing timetable that works for every UK farm.

Instead, think of the year as a series of planning stages.

Review: Understand previous consumption.

Forecast: Adjust historical figures for the coming year's workload.

Prepare: Check storage and supplier arrangements before demand increases.

Purchase: Order according to projected requirements and available storage.

Monitor: Compare actual consumption with the forecast.

Adjust: Increase or reduce future purchases when circumstances change.

Review again: Record what worked and what did not.

This cycle is far more adaptable than following a rigid monthly buying schedule.

Final Thoughts on Agricultural Oil Purchases

Planning agricultural oil purchases throughout the year is ultimately about giving the farm more control.

The objective is not to fill the tank at every opportunity or wait for a perfect fuel price.

It is to understand the business well enough to know when demand is likely to rise, how much fuel is required, how much stock should be available and when another order needs to be placed.

Historical consumption provides the starting point. The farming programme provides the forecast. Storage capacity establishes the practical limits. Supplier reliability determines how much flexibility the farm has. Regular monitoring keeps the plan relevant.

When these elements are brought together, fuel purchasing becomes a planned part of farm management rather than an emergency task carried out when the tank is nearly empty.

For UK agricultural businesses, that change in approach can make fuel expenditure easier to manage and, just as importantly, help keep essential machinery working when the farm needs it most.

Frequently Asked Questions About Agricultural Oil Purchases

How often should a farm plan its agricultural oil purchases?

The annual requirement should be forecast at the beginning of the farming year, but the plan should be reviewed throughout the year. More frequent checks are particularly useful during periods of high fuel consumption.

What information is needed to create an agricultural oil purchasing plan?

Previous fuel consumption, planned acreage, machinery use, seasonal workloads, storage capacity, supplier delivery times and expected fuel expenditure are useful starting points.

Should farmers buy agricultural oil in bulk?

Bulk purchasing can be appropriate when the farm has suitable storage, predictable consumption and a competitive delivered price. However, purchasing more fuel than the business can reasonably use may unnecessarily tie up capital.

When should agricultural fuel be ordered before harvest?

The order should be planned far enough ahead to allow the fuel to arrive before peak demand begins. The exact timing depends on expected consumption, tank capacity and the supplier's normal delivery times.

How can farmers avoid running out of agricultural fuel?

Establish a minimum stock level and reorder point based on actual consumption. During busy periods, monitor tank levels more closely and allow enough stock to cover possible delivery delays.

How can a farm reduce agricultural fuel purchasing costs?

Accurate forecasting, comparing delivered supplier prices, reducing emergency orders and improving machinery fuel efficiency can all contribute to better fuel cost management.

Is HVO suitable for agricultural machinery?

Suitability depends on the specific machine, manufacturer approval, fuel specification and intended application. Farmers should check the equipment requirements and applicable UK rules before switching fuels.

Should fuel consumption be measured by hectare?

For many arable farms, litres per hectare can be a useful performance measure. It should be considered alongside crop type, soil conditions, cultivation practices and the amount of work undertaken.

What should farmers do if they repeatedly need emergency fuel deliveries?

Review why the emergency orders are occurring. Repeated shortages usually indicate that the forecast, reorder point, storage strategy or supplier arrangements need to be changed.

What is the most important part of an annual agricultural fuel plan?

Knowing when the farm's highest fuel demand is likely to occur. Once peak demand is understood, the farm can plan stock levels, delivery timing and contingency requirements much more effectively.
