What you get with your free car spec check
A free ServiceStamp spec check returns the full manufacturer-coded specification for any UK registration, alongside the live DVLA tax and MOT data.
| Data point | What you'll see |
|---|---|
| BHP & torque | Maximum power output and torque, in line with the manufacturer's figures. |
| Fuel type | Petrol, diesel, hybrid, plug-in hybrid, electric or alternative fuel. |
| Transmission & drivetrain | Manual or automatic, and front, rear or all-wheel drive. |
| Engine size | Engine displacement in cc. |
| Kerb weight & gross weight | Unladen and maximum permissible weights. |
| Body type & doors | Hatchback, saloon, estate, SUV, coupe, convertible, plus door count. |
| Dimensions | Length, width and height where DVLA holds the data. |
| CO2 emissions | CO2 output in g/km, the figure that drives VED bands and clean-air charges. |
| Euro emissions standard | Euro 4, 5, 6 or 7, which determines ULEZ and Clean Air Zone eligibility. |
| Make, model & colour | DVLA-recorded identity of the vehicle. |
The free spec check covers the technical and identity picture DVLA holds. For finance, write-off, stolen markers and multi-source mileage analysis before buying, the Vehicle History Check (£14.99) adds the deeper risk data.

What the free spec check returns
A used-car listing is a sales document. The DVLA-coded spec is the official record of what the car actually is. When the two disagree, the listing is wrong, the seller is mistaken, or something more concerning is going on. A free spec check is the simplest way to confirm what you are looking at before you spend time and money on a viewing.
The free ServiceStamp spec check returns the engine displacement, fuel type, transmission, drivetrain, kerb weight, body type, doors, dimensions, CO2 emissions and Euro standard for any UK reg. Power and torque figures come from manufacturer data coded against the chassis, which means they reflect the original factory spec for that variant rather than a generic model-wide figure.

Why specs matter when buying used: mismatch as a fraud signal
Spec mismatches between an advert and the DVLA record are one of the easiest red flags to catch in advance. The causes range from the harmless (a careless seller copied the wrong trim level from a manufacturer brochure) to the serious (the car has been cloned and the visible plates do not match the chassis they are attached to).
Things to compare between the advert and the DVLA spec:
- Engine size and BHP figure (a popular target for misleading adverts)
- Transmission type (manual vs automatic vs DSG)
- Body type and door count (3-door vs 5-door, saloon vs estate)
- Colour (the DVLA-recorded colour should match the photographs unless a respray is declared)
- Fuel type (the difference between diesel and petrol versions of the same model can be substantial)
- CO2 emissions and Euro standard (matters for ULEZ and tax)
Modest discrepancies usually indicate seller error. Significant mismatches, especially across two or more data points, warrant a paid Vehicle History Check (£14.99) and an in-person identity verification of VIN, chassis stamps and door-pillar plates before any money changes hands.
BHP, torque and performance figures explained
BHP (brake horsepower) measures the maximum power the engine can produce, typically expressed at the engine's peak rpm. It is the headline number drivers care about because it correlates loosely with acceleration and top-end performance. Two cars with similar BHP can feel very different if their torque curves are dissimilar.
Torque, measured in Newton metres (Nm) or pound-feet (lb-ft), is the rotational force the engine produces. It determines how quickly the car accelerates from low speeds, how easily it climbs hills, and how confident it feels in normal driving. Modern diesels and electric motors usually have much higher torque than equivalent petrol engines, which is why they feel stronger from a standing start.
Power-to-weight ratio (BHP per tonne) is a better real-world performance indicator than BHP alone. A 1,200kg hot hatch with 200 BHP (167 BHP/tonne) feels quicker than a 1,800kg SUV with 250 BHP (139 BHP/tonne). The free spec check returns the kerb weight alongside, so the calculation takes seconds.
Fuel type, CO2 and ULEZ implications
Fuel type is more consequential than ever in 2026. Apart from running costs, it determines clean-air-zone eligibility, VED rate, company-car BIK, and increasingly insurance premiums in city postcodes. The free spec check returns fuel type, CO2 output and Euro standard in the same response.
The Euro standard is the critical figure for ULEZ and other UK clean-air zones. Petrol cars need to meet Euro 4 (broadly cars first registered from 2006 onwards) to avoid the daily charge. Diesel cars need to meet Euro 6 (broadly cars first registered from September 2015 onwards). A non-compliant car driven into central London attracts a £12.50 daily ULEZ charge, 24 hours a day except Christmas Day. PCNs for non-payment are £180, halved to £90 if paid within 14 days.

Body type, dimensions and kerb weight
Body type and dimensions matter more than buyers often realise. A 4.7m saloon and a 4.7m estate share the same footprint but have very different practicality. A 1,950kg kerb weight pushes a car into a different insurance group and trailer-licence bracket from a 1,500kg equivalent. The free spec check returns the official DVLA figures for all of these, so you can plan parking, garage space and insurance before viewing.
Kerb weight and gross weight together also tell you how much load the vehicle can legally carry, important for traders, families with bulky equipment, and anyone who tows. Combined with the towing capacity figure on the V5C, these numbers determine whether a given trailer or caravan setup is legal.
Cross-referencing the body type and door count against the advert photographs is also one of the easier ways to spot a cloned car. A "5-door hatchback" in the listing for a car the DVLA records as a 3-door is a clear contradiction worth investigating.
Spec data sources, accuracy and edge cases
The free spec data comes from two places: the DVLA Vehicle Enquiry service (which holds the registered identity, engine size, fuel, transmission, body type, CO2, Euro standard, colour and weights) and manufacturer data coded against the chassis (which adds BHP, torque, dimensions and trim-specific detail).
Accuracy is high for cars first registered in the UK, especially mainstream models from the last 15 years. Edge cases where the data can be sparse or out of date: imported vehicles (where DVLA holds only the registered identity, not the original manufacturer figures), very new or very low-volume models (where manufacturer data has not yet been coded), modified cars (where the physical engine and the registered engine may not match), and historic vehicles (where original spec is sometimes incomplete).
For any of those edge cases, treat the spec figures as a guide and verify the physical vehicle against its V5C and chassis stamps. For the full set of risk data including finance, write-off and stolen markers, the Vehicle History Check (£14.99) brings the deeper picture. The full used-car buying checklist walks through how these pieces fit together at the kerbside.

Pair the report with a physical inspection
A digital spec check is essential, but it isn't a substitute for looking at the car. Worn tyres, corrosion, poor crash repairs and electrical faults all show up only in person, and a structured walk-around catches things even an honest seller may not have noticed. Our used-car buying checklist takes you through bodywork, tyres, suspension, brakes, fluid levels, electrical functions and the test drive itself.
For spec verification specifically, cross-check the VIN at the windscreen, door pillar and chassis stamp against the V5C, and confirm the engine and transmission variant against the DVLA-coded spec.
