FuelTyp
BLOCK: BVehTab / QTVEHTAB.INC
SUMMARY
Question placement moved.
DETAILS OF CHANGE
Moved from the vehicle questionnaire to the household questionnaire. The question is asked for each vehicle.
The version of the question for 2025 (which itself remains unchanged) is shown below:
Ask for all vehicles:
FuelTyp
VEHICLE
What fuel does the [VEHICLE]’s engine use?
INTERVIEWER Bi-fuel is a combination of any two of petrol or diesel or ethanol with national gas or LPG.
- Petrol
- Diesel
- Electric/Battery only
- Hybrid
- Plug-in hybrid
- Liquefied Petroleum Gas (LPG)
- Bi-fuel (combination of two fuels)
- Other (SPECIFY)
Helpscreen:
Electric/battery vehicle relies entirely on electricity for fuel and can be plugged into the mains. It has a battery pack and electric motor. The vehicle cannot be filled up with any type of fuel.
Hybrid vehicle is mostly powered by an internal combustion engine and uses electricity to help drive the wheels. The battery is only recharged when the vehicle is in use and cannot be plugged into the mains. The vehicle requires petrol or diesel to fuel the internal combustion engine.
Plug-in hybrid vehicle combines both a battery pack and electric motor with an internal combustion engine. Both the electric motor and the internal combustion engine can drive the wheels. The battery is recharged by plugging it into the mains, though it can also be partly recharged when in use. The vehicle requires petrol or diesel to fuel the internal combustion engine.
NOTES
This question was moved as it is used as a filter for some of the following electric vehicle charging questions, which have also been moved. The text itself remains unchanged.
DomCha, DCSma, DCAcc
BLOCK: BVehTab / QTVEHTAB.INC
SUMMARY
Question placement moved.
DETAILS OF CHANGE
Questions on electric / battery only, or plug-in hybrid vehicle charging have been moved from the vehicle questionnaire to the household questionnaire. These questions were previously asked for each electric / battery only, or plug-in hybrid vehicle in the household, but from 2025 onwards are now asked once at the household level.
The question text and routing remain unchanged for 2025.
Question ‘DomCha’ is shown below for reference:
ASK IF any vehicle is an electric/battery only or plug-in hybrid (FuelTyp=3,5)
DomCha
VEHICLE
Do you own a domestic chargepoint for charging your [IF FuelTyp=3 “electric vehicle” / IF FuelTyp=5 “plug-in hybrid vehicle”] for your household’s own personal use?
INTERVIEWER: by “domestic chargepoint” we mean a dedicated vehicle charging unit, either fitted to an external wall of a home or a floor-mounted standalone unit on the grounds of the household’s property
INTERVIEWER: this is for charging electric/battery only vehicles or plug-in hybrid vehicles
- Yes
- No
Helpscreen:
By “domestic chargepoint” we mean a dedicated vehicle charging unit, either fitted to an external wall of a home or a floor-mounted standalone unit on the grounds of the household’s property. These units can provide charge to an electric/plug-in vehicle’s battery at a quicker rate than charging via a UK-standard three-pin plug socket (i.e. the plug sockets you would find in your home or garage to power normal household appliances).
If the household has a private arrangement to share a domestic chargepoint with a neighbour then Record “No”.

Two old versions of this question were removed for 2025. HLongA was asked to the HRP at the household level and HLongInd was asked of all other adults interviewed face-to-face. The wording of HLongA and HLongInd remain unchanged for HLongIndB.

We are interested in knowing whether people have moved house recently because that could affect their travel behaviour, especially if they have moved out of the immediate neighbourhood.
In case respondent has moved away from the current address either for school, work or relationship and then returned to the same address, code in the continuous period of time since their return.

Helpscreen:
INTERVIEWER: IF RESPONDENT REQUESTS HELP OR CLARIFICATION ABOUT WHAT IS CLASSIFIED AS A “LONG-LASTING CONDITION” OR “ILLNESS”, READ THIS TEXT BELOW:
What is and is not covered
As a guide this standard includes physical or mental health conditions:
• lasting or expected to last for 12 months or more
• that a person is likely to have for the rest of their life
• that are likely to need some level of supervision and treatment over a long period of time
• that are not curable, even if medication or treatment can control symptoms
• which flare up intermittently, but the exacerbation has a shorter duration than 12 months (for example, hayfever)
• which may not be perceived as serious and do not affect day-to-day activities but are nevertheless long lasting
• which are managed by treatment and lifestyle adjustments and do not affect day-to-day activities, but are nevertheless long lasting
This standard does not capture temporary conditions, however serious they might be.
What this question is designed for
The question is designed to include:
• sensory deficits
• non-temporary mobility problems including dyspraxia and cerebral palsy
• developmental conditions such as Autism Spectrum Disorder (ASD), which includes Asperger’s syndrome, and Attention Deficit Hyperactivity Disorder (ADHD)
• conditions associated with learning impairments such as Down’s syndrome or dyslexia
• common conditions and illnesses, such as asthma, diabetes, heart and other circulatory conditions, respiratory conditions, digestive conditions, anxiety and depression — if they have lasted or are expected to last 12 months or more
• seasonal conditions such as hay fever which recur and have lasted or are expected to recur in the future
