Our guide to the impact of WLTP on commercial vehicles, company cars and taxation
One of the most significant changes to affect the industry in many years is the introduction of WLTP. Testing under this methodology is already underway for all passenger cars, and manufacturers are currently working towards all light commercial vehicles being tested under this by September 2019. Read on to discover why WLTP is the new standard and what it means for you and your drivers.

What is WLTP?
Worldwide harmonised Light-duty vehicles Test Procedure (WLTP) is a new test procedure for the measurement of fuel economy and emissions data. It has been introduced to give a more realistic view of the fuel economy and emissions performance achievable in real-world driving conditions. It supercedes the previous NEDC (New European Driving Cycle) test procedure.
WLTP will allow you to compare vehicles’ environmental performance more confidently
The driving cycles used for the NEDC test – the familiar urban, extra-urban and combined – have been replaced by a set of driving ranges – low speed, medium speed, high speed, extra-high speed and combined – that more closely represent how vehicles are used today. These driving ranges were determined following the analysis of data collected from real journeys from across the world.
Since the WLTP methodology is fundamentally different to NEDC, it isn’t possible to meaningfully compare one set of figures against the other. Recognising this difficulty, the EU has developed a formula which translates the WLTP figures into NEDC-correlated versions. This will allow comparison between vehicles type-approved under the different regulations, but it’s important to bear in mind that these figures will have been generated under the WLTP test conditions, and as such are likely to be higher.
WLTP remains a laboratory test, in order to guarantee consistent test conditions and therefore allow meaningful comparisons between vehicles.
We are working with our vehicle and data partners to bring you this new information in the clearest way possible.
How WLTP could impact your fleet costs
It’s important to understand that the WLTP methodology doesn’t change the real-world fuel economy or emissions that a vehicle produces. However, it will impact whole-life cost calculations on both passenger cars and commercial vehicles: the calculated fuel costs will increase but, on a positive note, become more accurate.
It is also likely to impact employees’ benefit-in-kind costs, because the NEDC-correlated CO2 figure will have been generated under the WLTP driving conditions. Where a company vehicle is made available for an employee’s private use, employers’ Class 1A National Insurance Contributions will also be affected.
It’s also worth considering the implications for your company’s vehicle choice list if this is based on CO2 emissions: doing nothing could mean that certain vehicles suddenly fall outside of the parameters. Your Volkswagen Financial Services | Fleet Account Manager can offer any advice you need.
How WLTP could impact company car tax
Since the Benefit-in-Kind (BiK) tax that a company car driver pays is based on the vehicle’s CO2 emissions, and we’ve already seen that reported CO2 emissions could increase under WLTP, there is clearly the possibility of an impact on drivers’ BiK costs. The impact will differ depending on when the vehicle is first registered:
- For all new registrations before 6 April 2020 the NEDC emissions figure is used to calculate tax, so there will be no impact on these vehicles. Drivers could see an increase in their BiK tax costs because the NEDC-correlated figure is calculated from the WLTP driving cycles. This will be particularly noticeable for drivers replacing vehicles on a like-for-like basis. These rates will remain the same for 2021/22 and 2022/23 tax years.
- For all new registrations from 6 April 2020 tax will be based on the vehicle’s WLTP CO2 emissions figure. The Government has created a second BiK table which reduces the tax by 2 percentage points for the majority of bandings.
- From 2023/24 tax year, for vehicles registered before 6 April 2020 and vehicles registered after 6 April 2020 the tax rates will be the same.
Drivers might also see a change to the vehicles available on their choice list, though this will depend on whether the company adjusts its list to allow for the higher CO2 values.
WLTP timeline for cars and light commercial vehicles (LCVs)
No vehicles registered before 1 September 2017 are affected by the introduction of WLTP. From this date, all new passenger car types presented for type approval must have been tested under the WLTP regime.
All new passenger cars registered from 1 September 2018 have type-approved WLTP figures, as must all new LCV types. From 1 September 2019, all new LCVs registered must have WLTP figures.
WLTP will determine changes to vehicle tax rates from April 2020
Up until 5 April 2020, all vehicles will be taxed based on their NEDC or NEDC-correlated CO2 emissions figure. This is the case for both Vehicle Excise Duty (VED) and benefit-in-kind taxation. Any vehicle registered up to this point will continue to be taxed on this basis for the balance of its operating life. All passenger cars registered after this date (i.e. from the start of 2020/21 tax year) will be taxed on the basis of their WLTP CO2 emissions figure.
The introduction of WLTP will have no impact on any vehicles you are currently operating. When a vehicle is first registered it has a CO2 emissions value associated with it; this value will not change for the life of the vehicle. Its future tax treatment for benefit-in-kind and Class 1A National Insurance purposes will continue to be based on this figure.
From 1 September 2017 – all new types of passenger cars must be issued with WLTP and NEDC-correlated data.
From 1 September 2018 – all new passenger cars registered must be issued with WLTP and NEDC-correlated data. All new types of light commercial vehicles must be issued with WLTP and NEDC-correlated data.
From 1 September 2019 – all new light commercial vehicles registered must be issued with WLTP and NEDC-correlated data.
From 6 April 2020 – the basis for taxation for all new vehicles registered moves to WLTP.
The NEDC test was introduced in 1992 and based on theoretical driving conditions. In subsequent years, there have been significant changes in vehicle technology and driving patterns, and the figures generated have become less representative of what is attainable in the real world.
The WLTP test has been introduced to produce a set of values that are much more representative of real-world fuel economy and emissions. The driving cycles used have been developed following the analysis of data from many thousands of real journeys from across the world. The duration of the test has been increased from 20 to 30 minutes; the distance travelled from 11km to 23.25km; the average speeds have been increased, and the amount of time spent idling has been reduced. The other significant change to the test is that the impact of vehicle options, such as wider tyres or heavier items such as leather trim, is also considered. This is why you will begin to see low and high values for the fuel economy and emissions data.
It’s important to note that, whilst the driving cycles are based on the analysis of real-world journeys, the tests themselves are still performed under laboratory conditions. This is to ensure that valid comparisons can continue to be made between vehicles.
Because the test procedures are very different it is not reasonable to directly compare NEDC against WLTP figures. Recognising this difficulty, the EU has developed a formula (known as CO2MPAS) that takes the WLTP figures and converts them to a set of NEDC-correlated figures in the traditional urban, extra-urban and combined format. These are intended to reflect what the vehicle would have achieved under the ‘old’ NEDC test, and thus allow comparisons to be made. It’s important to note that these figures are based around the WLTP driving cycles, so may not be identical to those that would have been achieved under the NEDC test itself. They also do not include the fitment of any options.
Expectation is that fuel consumption and CO2 emissions values are likely to be increased by approximately 10-20%, though certain types of vehicles will be more heavily affected than others. Hybrids and plug-in hybrids are likely to show a greater increase due to more emphasis being placed on ‘open road’ driving, and so the benefit of stop/start systems is likely to be reduced due to the reduction in time spent idling.

Electric vehicles will also be assessed under the new WLTP regime. Whereas under the NEDC procedure they were given a single range figure, with WLTP they will be issued with two range figures: combined and a new city range. As with petrol and diesel vehicles, this is intended to give a better representation of the sort of range available in the real world.
The RDE (Real-world Driving Emissions) test is a companion test to the WLTP regime. As its name suggests, it is a test carried out in the real world rather than the laboratory, and its intention is to ensure that the figures achieved under laboratory conditions are repeatable in the real world, with a degree of tolerance. It too has a phased introduction. RDE step 1 allows a vehicle to emit up to 2.1 times the amount of NOx allowed under laboratory conditions, whilst RDE2 reduces this allowance to 1.5 times.
This is particularly important for diesel vehicles because, in the Autumn 2017 Budget, the Chancellor announced that any diesel vehicle that is certified as meeting RDE2 will be exempt from the 4% diesel surcharge in benefit-in-kind. It will also be exempt from the 1-band increase in first year Vehicle Excise Duty.
Up until 5 April 2020, the NEDC and NEDC-correlated CO2 emissions figures will be used for taxation purposes so there is no reason to suppose that tax costs will increase above what is already known up to this point. From 6 April 2020, taxation will be based on the WLTP CO2 emissions figures.
The Government has created 2 BiK tables, the vehicles registered before 6 April 2020 will have their 2020/21 rates frozen for the following 2 years. Those vehicles registered from the 6 April 2020 will use an adjusted table that reduces the 2020/21 rates by 2 percentage points, these will increase by a percentage point a year up to 2022/23. In both instances, diesel will continue to add 4% up to a maximum of 37% unless RDE2 compliant.
Zero-emission vehicles registered before or after 6 April 2020 will qualify for 0% BiK in 2020/21 tax year, increasing by one percent a year until 2022/23.
Class 1A National Insurance will now be using this 2 table, structure.
With regards to first-year Vehicle Excise Duty costs, no comment has been made on this subject in any budget statement to date, so the situation remains uncertain.
