BMW i4 running costs: what UK ownership really costs
BMW i4 UK running costs: fuel or electric, insurance group, road tax, servicing and depreciation.

The BMW i4 offers competitive running costs for an electric vehicle, with low charging expenses, insurance group ratings from 31 to 34, and a tax band of 1. Its servicing intervals are typically every 18,000 miles or 24 months, and depreciation is moderate, making it a solid choice for cost-conscious drivers.
Fuel and Charging Costs
The BMW i4 is an all-electric vehicle, which means fuel costs are significantly lower than those of traditional petrol or diesel cars. Charging at home can cost around £7 to £10 for a full charge, depending on your energy provider and tariff. Public charging stations may vary in price, with rapid chargers costing more per kWh. The i4 has a range of approximately 300 miles on a full charge, making it suitable for both daily commutes and longer journeys without frequent recharging.
For those who can charge at home, the cost-effectiveness of the i4 becomes apparent. The average UK household pays around 34p per kWh, meaning a full charge from empty to full could cost approximately £10. This translates to a cost of around 3p per mile, which is significantly lower than the average cost of petrol or diesel vehicles.
Insurance Group
Insurance for the BMW i4 falls within groups 31 to 34, depending on the specific model and trim level. This places it in a relatively affordable bracket for electric vehicles, especially when compared to high-performance petrol alternatives. The cost of insurance will vary based on factors such as your driving history, location, and the level of cover you choose.
Drivers should expect to pay anywhere from £600 to £1,200 annually for insurance, depending on their profile. It is advisable to shop around and compare quotes from various insurers to find the best deal. Additionally, many insurers offer discounts for electric vehicles, which can further reduce costs.
Tax Band
The BMW i4 is classified in tax band 1, which means it benefits from zero road tax in the first year of registration. This is a significant advantage for electric vehicle owners, as it reduces the overall cost of ownership. After the first year, the annual road tax remains low, making it an attractive option for budget-conscious drivers.
Moreover, the i4 qualifies for the UK government’s plug-in car grant, which can further offset the initial purchase price. This financial incentive, combined with the zero emissions of the vehicle, makes it an appealing choice for environmentally conscious consumers.
Servicing Intervals
Servicing for the BMW i4 is recommended every 18,000 miles or every two years, whichever comes first. This interval is relatively generous compared to traditional petrol or diesel vehicles, which often require more frequent servicing. The electric powertrain of the i4 has fewer moving parts, which contributes to lower maintenance costs over time.
While electric vehicles generally have lower servicing needs, it is still essential to adhere to the manufacturer’s guidelines to ensure optimal performance and longevity. Regular checks on the battery health, brakes, and tyres are vital, as these components can wear differently compared to conventional vehicles.
Typical Depreciation
Depreciation for the BMW i4 is moderate, typical for electric vehicles in its class. While electric cars tend to depreciate faster than their petrol counterparts initially, the i4’s strong brand reputation and performance capabilities help it retain value better than many rivals. Factors such as mileage, condition, and market demand will influence the resale value.
On average, electric vehicles can lose around 50 to 60 percent of their value over the first three years. However, the i4’s appeal and the growing acceptance of electric vehicles may help it perform better in the used car market. As more consumers shift towards electric options, the demand for models like the i4 is likely to remain strong.
Conclusion
The BMW i4 presents a compelling case for those looking for an electric vehicle with manageable running costs. With low charging expenses, reasonable insurance rates, minimal road tax, and moderate servicing and depreciation, it stands out as a practical choice for UK drivers. Whether for daily commuting or longer journeys, the i4 combines efficiency with performance, making it a worthy investment for the future.
