Five questions before looking at models
Answering these first prevents a large battery or low monthly payment from distracting from the way the car will actually be used.
Where will it charge?
Home, work, public charging or a genuine mixture. Check the price and reliability of the option you will use every week.
What is the longest regular trip?
Use the longest normal monthly journey rather than buying around one exceptional annual trip.
How long will you keep it?
Battery chemistry, warranty, finance and depreciation matter differently over three years and ten years.
What must it carry?
Test the usable boot shape, rear seats, roof-load and towing limits with your real family, dogs or equipment.
What is the complete cost?
Add deposit, payments, final payment, insurance, electricity, public charging, tyres and optional products.
02 / BATTERY TYPE
Choose chemistry around your priorities
The battery name affects range per kilogram, lifespan, materials and charging behaviour—but the engineering of the complete pack still matters.
LFP / BYD Blade
Our first choice for many long-term private buyers because of cycle life and thermal stability. The trade-off is normally lower energy density.
NMC
Higher energy density can provide more range from a lighter and more compact pack, but frequent high states of charge generally need more care.
Sodium-ion and solid-state
Worth understanding, but not a reason to delay buying a suitable current car. UK choice and long-term ownership evidence remain limited.
03 / RANGE & EFFICIENCY
Look beyond the advertised miles
WLTP is useful for comparing cars tested under a common procedure. It is not a guarantee of motorway, winter or towing range.
How much stored energy the driver can use.
Energy used under the relevant conditions.
A scenario estimate, not a fixed promise.
Compare miles per kWh
Efficiency tells us how far the car travels with its battery energy. It affects charging cost, journey time and how much expensive battery capacity is needed.
Test the difficult scenario
Ask whether the car covers your regular winter motorway trip with a sensible arrival buffer. Heating, speed, cold air, wet roads, roof boxes and towing can all reduce range.
Instead of asking “What is the range?”, ask “What range should we expect on our normal winter motorway journey, and how quickly can we add the next 100 miles?”
04 / CHARGING
Peak power is not the whole charging story
| Specification | What it means | What we would check |
|---|---|---|
| AC charging | Charging at home or many destination chargers through the car's onboard charger. | 7 kW is common at home. An 11 kW onboard charger is useful where three-phase AC is genuinely available. |
| Peak DC rate | The highest rapid-charging power the car may briefly accept. | Do not rank cars by the peak alone. Compare a tested 10–80% time and the average power across that session. |
| Charging curve | How charging power rises and falls as the battery fills. | A lower peak held consistently can be faster than a large headline figure that lasts only briefly. |
| Preconditioning | Heating or cooling the battery towards a suitable rapid-charging temperature. | Check whether it is automatic through navigation and whether it can be started manually. |
| 800-volt system | An architecture that can support high power with lower current on compatible equipment. | Useful, but judge the finished car by actual charging time, charger compatibility and repeatability. |
| Charge-port position | Determines whether cables reach when parking forwards, backwards or beside a charger. | Test it against the driveway and the public charging networks you expect to use. |
05 / EQUIPMENT
Features that can materially improve ownership
Some equipment changes everyday usability. Other features sound impressive but may have little value for your journeys.
Battery preconditioning
Improves the chance of repeatable rapid charging in cold or hot conditions.
Reliable route planning
Should plan charging stops and ideally use live charger status and arrival charge.
Heat pump
Can reduce cabin-heating power compared with resistance heating, especially on frequent winter journeys.
11 kW AC charging
Valuable at compatible workplace or public AC chargers; often no faster on a normal single-phase home supply.
Vehicle-to-load
Allows the car to power suitable external devices. Useful for camping, tools or emergency backup of small loads.
Driver assistance
Test speed warnings, lane assistance and driver monitoring. The quality and ease of control matter more than the number of acronyms.
App and remote controls
Confirm scheduled charging, cabin preheating, charge limits and shared-driver access actually work in the UK app.
Towing and roof load
Do not assume an EV can tow or carry a roof box. Check the exact model's approved limits.
06 / WARRANTY & COST
Read the retained-capacity wording
A long battery warranty is useful only when we understand what it covers and the threshold that triggers a claim.
- Time and mileageCoverage normally ends when either limit is reached.
- Capacity thresholdCheck the minimum state of health required for a degradation claim.
- Transfer conditionsConfirm the warranty follows the car when it is sold.
- Servicing rulesUnderstand required inspections and record keeping.
- InsuranceGet a real quote before ordering; similar EVs can sit in very different groups.
- TyresPrice the exact size and type, particularly for large wheels and EV-specific load ratings.
07 / BEFORE SIGNING
Our EV test-drive checklist
- 1
Bring the real load. Test child seats, dogs, pushchairs, luggage or work equipment rather than relying only on litres.
- 2
Use the menus. Adjust climate control, driver assistance, charging limit and regenerative braking without help from the salesperson.
- 3
Check the charging plan. Confirm cable reach, charge-port position, tariff compatibility and realistic public alternatives.
- 4
Price the complete term. Record deposit, every payment, final payment, mileage allowance, excess-mile rate and all optional products.
- 5
Leave with the paperwork. Take time to compare the written quote, warranty and product documents away from the dealership.
COMMON QUESTIONS
Frequently asked questions
What should we check first when buying an electric car?
Start with where the car will normally charge, then compare the longest regular journey with a realistic winter and motorway range. After that, check efficiency, rapid-charging performance, warranty, insurance and the complete finance cost.
Is a bigger EV battery always better?
No. A bigger pack can add range, but it also adds weight and cost. An efficient car with a suitable charging curve may be easier and cheaper to own than a heavier car carrying battery capacity you rarely use.
Is WLTP the range we will get in real driving?
WLTP is a controlled laboratory test that helps compare vehicles. It is not a promise for every journey. Speed, temperature, heating, tyres, rain, load and driving style can all change real-world range.
Is a heat pump worth paying for?
It is most useful for drivers making frequent winter journeys because it can heat the cabin more efficiently than resistance heating in suitable conditions. Its value depends on climate, trip length, price and whether it is standard equipment.
Do we need 800-volt charging?
Not necessarily. It can support very fast charging on a compatible charger, but the vehicle's actual 10–80% time, average charging power and battery preconditioning are more useful than voltage alone.
