What are HMRC Advisory Fuel Rates in 2024?

Understanding HMRC Advisory Fuel Rates in 2024 for the UK

Introduction to HMRC Advisory Fuel Rates

The HMRC Advisory Fuel Rates (AFR) are guidelines set by HM Revenue and Customs (HMRC) to regulate the reimbursement rates for drivers using company cars. These rates are particularly important for businesses and employees to manage costs effectively while complying with tax regulations.

What are HMRC Advisory Fuel Rates in 2024

Changes in Advisory Fuel Rates for 2024

For the year 2024, the HMRC has made several updates to the advisory fuel rates, effective from different dates. Starting March 1, 2024, the advisory rates were adjusted based on the latest fuel price trends and engine efficiency metrics. These rates apply until they are revised again, typically on a quarterly basis. As of June 1, 2024, the rates were adjusted again to reflect ongoing market changes.

Here’s a breakdown of the advisory fuel rates from March 1, 2024, to May 31, 2024, and from June 1, 2024, onwards:

  • From March 1, 2024, to May 31, 2024:

  • Petrol vehicles: Rates range from 13 pence per mile for vehicles with an engine size of 1400cc or less to 24 pence for those over 2000cc.

  • Diesel vehicles: Start at 12 pence per mile for vehicles up to 1600cc, increasing to 19 pence for those over 2000cc.

  • LPG vehicles: 11 pence per mile for vehicles with an engine size of 1400cc or less, rising to 21 pence for those over 2000cc.

  • Fully electric vehicles: 9 pence per mile.

  • From June 1, 2024:

  • Petrol rates increase slightly, with vehicles over 2000cc costing 26 pence per mile.

  • Diesel rates are adjusted to 13 pence for vehicles up to 1600cc and 20 pence for those over 2000cc.

  • LPG rates remain unchanged from the previous quarter.

  • Fully electric vehicles see a decrease to 8 pence per mile.

Application of Advisory Fuel Rates

The advisory fuel rates are applicable under specific circumstances:

  • They are used to reimburse employees for business travel in their company cars.

  • Employers require employees to repay the cost of fuel used for private travel.

It's important to note that using the advisory fuel rates correctly ensures that there are no taxable profits and no Class 1A National Insurance contributions on these payments. However, if employers reimburse at rates higher than the advisory rates without justifying the higher costs, it may lead to taxable benefits.

Understanding and applying the correct advisory fuel rates is crucial for both businesses and employees to ensure compliance and efficient cost management in company car operations. Employers and employees should regularly check for updates from HMRC to stay informed about the latest rates applicable for their vehicle types and usage scenarios.

Practical Implications of HMRC Advisory Fuel Rates

Impact on Business Expenses and Reimbursements

The HMRC advisory fuel rates (AFR) not only guide companies on reimbursing employees for business travel but also serve as a benchmark for managing fuel expenses efficiently. For businesses, adhering to these rates means ensuring compliance with tax regulations and avoiding unnecessary tax liabilities.

Scenarios for Using Advisory Fuel Rates

  • Reimbursements for Business Travel: When employees use their company cars for business purposes, companies can use the AFR to reimburse them. This reimbursement does not lead to any taxable profit or Class 1A National Insurance contributions if it does not exceed the advisory rates.

  • Private Travel Costs: If employees use their company car for private purposes, they should repay the cost of fuel at the AFR rate to avoid any additional tax charges. This ensures that the use of the company car remains cost-neutral from a fuel perspective.

Calculating and Applying AFR

The calculation of AFR takes into account several factors including the average price per litre of fuel and the average miles per gallon (MPG) that vehicles of different engine sizes can achieve. For example, the rates for petrol cars in June 2024 are based on the fuel efficiency and cost per litre of petrol:

  • Up to 1400cc: 14 pence per mile

  • 1401cc to 2000cc: 16 pence per mile

  • Over 2000cc: 26 pence per mile

For diesel and LPG cars, similar calculations are made taking into account their respective fuel efficiencies and costs.

Flexibility and Exceptions

Companies may set their own rates higher than the AFR if they can justify that the fuel costs per mile exceed the advisory rates due to exceptional circumstances like using highly fuel-efficient cars or if the geographical area has higher fuel prices. However, any reimbursement above the advisory rate without proper justification is considered a taxable benefit.

Moreover, businesses may find themselves in situations where setting a rate lower than the AFR works in their favor, especially if they can prove lower operational costs. Employees can then claim Mileage Allowance Relief for any shortfall between the reimbursed amount and the AFR.

Businesses must regularly review and adjust their reimbursement policies according to HMRC’s AFR to ensure compliance and cost-effectiveness. Understanding these rates helps in setting clear policies for employee reimbursements and fuel cost management, which is crucial for maintaining financial efficiency and tax compliance.

Strategic Considerations for HMRC Advisory Fuel Rates

Enhancing Business Strategy with AFR

Understanding and strategically applying HMRC Advisory Fuel Rates (AFR) can significantly influence a company's financial planning and employee reimbursement policies. Businesses can leverage these rates not only for compliance but also for optimizing operational costs related to company vehicles.

Key Strategies for Using AFR

  1. Budget Forecasting and Financial Planning: Companies can use the advisory rates for forecasting fuel costs for budgeting purposes. By anticipating adjustments in AFR, businesses can better plan their finances and adjust their budgets to accommodate changes in fuel prices, which can fluctuate due to market conditions.

  2. Tax Efficiency and Compliance: Using AFR correctly ensures that companies remain compliant with UK tax regulations, avoiding unnecessary tax liabilities and penalties. It's essential for businesses to keep abreast of changes to the AFR to maintain compliance and ensure that all reimbursements are made according to the latest standards.

  3. Employee Reimbursement Policies: By aligning reimbursement policies with the AFR, businesses can provide clear guidelines to employees regarding the use of company cars. This helps in managing expectations and preventing disputes related to travel expenses.

Challenges and Solutions

While the advisory rates provide a framework, they may not cover all scenarios, particularly in cases of high fuel efficiency or significantly fluctuating local fuel prices. Here are some common challenges and solutions:

  • High Fuel Efficiency: For vehicles that are more fuel-efficient than average, companies might find the standard AFR limiting. In such cases, it might be beneficial for companies to calculate their own rates based on actual costs and seek approval from HMRC for these rates to avoid overpayments or underpayments.

  • Fluctuating Fuel Prices: Local variations in fuel prices can make the standard AFR less applicable in certain regions. Companies operating in areas with higher fuel prices might consider applying for a variance from HMRC or adjusting the internal reimbursement rate while ensuring it's documented and justified to avoid tax issues.

The strategic use of HMRC Advisory Fuel Rates can play a crucial role in enhancing operational efficiency, ensuring tax compliance, and managing employee benefits effectively. Companies should adopt a proactive approach in reviewing these rates quarterly to adjust their policies accordingly and remain aligned with current economic conditions. This forward-thinking approach not only aids in compliance but also supports strategic financial planning and enhances overall business efficiency.

By understanding the nuances of HMRC advisory fuel rates, businesses can ensure they are maximizing their resources while staying compliant with UK tax laws. This comprehensive approach to managing company car expenses is essential for maintaining a competitive edge and fostering a transparent and equitable work environment.


Q1: What should a company do if its fleet has significantly lower fuel consumption than the HMRC advisory rates suggest?

A company can apply to HMRC to use a custom rate that reflects their actual fuel costs. This requires detailed records and potentially an audit of fuel receipts and mileage logs to support the lower rate application.

Q2: How can companies handle situations where employees frequently travel to areas with markedly higher fuel prices?

Companies can consider applying for a variation with HMRC to use higher rates specific to those regions. Alternatively, they can reimburse the excess cost as a separate item, ensuring it's clearly documented as such to avoid tax complications.

Q3: Are there any exceptions to the use of HMRC advisory fuel rates for electric company cars?

Yes, the advisory electric rate is specific to fully electric vehicles and doesn't apply to hybrid cars, which are treated according to their petrol or diesel components under the advisory fuel rates.

Q4: Can advisory fuel rates be used for volunteers driving on behalf of a charity?

Yes, volunteers driving for charity can use the advisory fuel rates to claim back fuel costs without tax implications, provided the charity reimburses them at or below these rates.

Q5: What happens if an employee does not claim reimbursement for business travel?

Employees who do not claim reimbursement for business travel can claim Mileage Allowance Relief on their tax return, allowing them to deduct business travel expenses from their taxable income.

Q6: How do seasonal changes or fuel shortages impact the advisory fuel rates?

HMRC reviews rates quarterly and may adjust them to reflect significant changes in the fuel market, such as seasonal variations or shortages, ensuring rates remain realistic and fair.

Q7: Are advisory fuel rates applicable to motorcycles or bicycles used for business travel?

No, HMRC provides separate rates for motorcycles and bicycles, which are not covered under the advisory fuel rates for cars.

Q8: What documentation is required to support claims made at advisory fuel rates?

Employees should keep detailed mileage logs and business travel records. Companies should also keep receipts of fuel purchases if they seek to justify a rate different from the advisory rates.

Q9: How does HMRC enforce compliance with advisory fuel rates?

HMRC can request documentation during audits or reviews and may impose penalties or tax adjustments if discrepancies or non-compliance with the advisory fuel rates are found.

Q10: Can advisory fuel rates be applied to travel between the UK and other countries?

Yes, but only for the portion of travel that occurs within the UK. Costs related to travel outside the UK may need to be calculated differently and comply with international tax laws.

Q11: What are the implications if an employer consistently uses lower rates than the HMRC advisory fuel rates?

Employees can claim the difference through Mileage Allowance Relief. If under-reimbursements are systemic, it might raise concerns during an HMRC audit regarding employment tax obligations.

Q12: How should companies treat advisory fuel rates in their accounting software?

Companies should set up their accounting systems to automatically apply the correct advisory fuel rates for expense reimbursements, ensuring accurate and compliant financial reporting.

Q13: What is the process for adjusting advisory fuel rates in the event of a significant economic event, like a financial crisis or fuel crisis?

HMRC has the flexibility to review and adjust rates more frequently than quarterly in extreme circumstances to reflect significant changes in the fuel market.

Q14: Can an employee claim higher rates than the advisory if they drive a luxury or high-performance vehicle?

No, advisory fuel rates are designed to cover typical fuel costs and do not account for higher costs associated with luxury or high-performance vehicles. Employees cannot claim higher rates without specific evidence and approval from HMRC.

Q15: What educational resources does HMRC provide to help understand and apply advisory fuel rates?

HMRC offers detailed guidance documents, webinars, and even direct consultations to help businesses understand and properly apply advisory fuel rates.

Q16: Are there any tax planning strategies related to advisory fuel rates that companies can utilize to optimize their tax positions?

Yes, companies can engage in tax planning by aligning their vehicle procurement strategies with vehicles that have favorable advisory fuel rates, thus maximizing tax-efficient reimbursements.

Q17: What role do advisory fuel rates play in corporate sustainability efforts?

Companies aiming for sustainability might use the advisory fuel rates to encourage the use of more fuel-efficient or electric vehicles, aligning financial incentives with environmental goals.

Q18: How do changes in oil prices directly impact the advisory fuel rates?

Changes in oil prices can lead to adjustments in the advisory fuel rates, as these are a significant factor in the cost of fuel, which HMRC considers during their quarterly review.

Q19: What considerations should be taken when setting up a company car policy that uses advisory fuel rates?

A company car policy should clearly outline how the advisory fuel rates are applied, include procedures for logging business travel, and set out the process for reimbursement and any necessary repayment adjustments.

Q20: Are employees required to report their use of advisory fuel rates on their personal tax returns?

No, employees are not required to report the use of advisory fuel rates on their personal tax returns unless they are claiming Mileage Allowance Relief for any shortfall between the actual reimbursement received and the advisory rates.
