A BYD shortlist should begin with charging access, then body shape. Seal and Sealion 7 both offer an electric proposition, but a lower saloon and a taller coupe-shaped SUV solve different passenger and loading needs. A Seal 6 Touring belongs in an estate discussion, whereas Dolphin Surf is a compact urban choice. Moving between them solely because a quotation looks attractive can lose the original requirement.
For business users, write down the driver’s typical week before discussing battery size. For private users, include the longest family journey that repeats often enough to matter. IVF can compare suitable vehicles through a funder panel, with the proposed car and agreement identified together. BYD’s manufacturer range establishes product choices; it does not establish which exact vehicle a broker can allocate or when it will arrive.
IVF provides a named specialist and free UK delivery, with the date confirmed for the chosen vehicle. Enquiries and quotations carry no charge or obligation. Ask about suitable two-, three- or four-year terms; the available agreement depends on the car and funder.
| Model line | Body and powertrain | What to decide |
|---|---|---|
| Dolphin Surf | Small electric hatchback | Check seating, battery and equipment for the urban brief. |
| Dolphin | Electric hatchback | Separate the battery versions and normal passenger load. |
| Dolphin G DM-i | Plug-in-hybrid hatchback | Different drivetrain from Dolphin; verify the UK version. |
| ATTO 2 | Compact SUV; electric/DM-i routes | Name the powertrain before comparing battery or tax. |
| ATTO 3 | Electric family SUV | Identify the earlier generation and its charging hardware. |
| ATTO 3 EVO | Separate electric SUV generation | Use EVO-specific specification, equipment and supply. |
| Seal | Electric saloon | Compare motor choice and lower-body access. |
| Seal 6 DM-i | Plug-in-hybrid saloon / Touring | Choose luggage opening and body before equipment. |
| Seal U DM-i | Plug-in-hybrid SUV | Match the version to a regular charging routine. |
| Sealion 5 DM-i | Plug-in-hybrid SUV | Keep its battery and equipment separate from Seal U. |
| Sealion 7 | Electric coupe-shaped SUV | Assess rear access, load opening and drivetrain. |
Model pages are catalogue routes, not confirmation of stock or a delivery date. Where a line has left the current UK range, the status is stated in its row. Confirm the exact UK generation, equipment and supply in your quotation.
Dolphin Surf, Dolphin and Dolphin G should remain three separate questions. The first two are electric hatchback routes; Dolphin G DM-i introduces an engine and a different energy calculation. ATTO 2 also needs its electric or DM-i version written explicitly. A model family name is not enough to establish the charging requirement.
Seal is separate from Seal 6 DM-i, and the latter needs saloon or Touring stated in the enquiry. Seal U and Sealion 5 have their own plug-in-hybrid specifications, while Sealion 7 is an electric SUV. Keep these distinctions in the written comparison rather than replacing them with a generic BYD hybrid category. If a supplier offers a different generation or a similarly named car, revisit battery, equipment and tax before accepting the substitution. This matters particularly when comparing an older ATTO 3 with the newer EVO route.
An electric BYD relies on charging for its usable energy. DM-i combines a rechargeable battery with a petrol engine. It is not a label for an electric car that simply happens to have a longer range, and its tax treatment must not inherit the electric rate. The fuel and charging pattern should be explained before comparing grades or performance.
A DM-i can suit regular charged local journeys combined with longer trips, but the petrol engine does not make charging irrelevant. If plugging in is unlikely, calculate the likely petrol use in that actual routine and compare alternatives. For an electric BYD, map dependable home, workplace or public charging. Neither technology delivers one universal cost per mile: tariff, fuel price, speed, weather and usage matter. A full-battery test figure or combined petrol-and-electric range should never be read as one continuous electric journey.
A BYD company-car choice combines the employer’s lease commitment with the driver’s benefit calculation. An electric Seal and a DM-i Seal 6 cannot be assigned the same BiK band merely because both are electrified. Use the precise registered emissions and certified electric range for a plug-in hybrid, including any qualifying transitional rules.
For a small fleet, record where each driver can charge and who pays for energy. A policy built around dependable workplace charging can differ from one serving drivers who park on the street. Compare consistent mileage and equipment, then take the resulting vehicle-specific figures to the company’s accountant.
VAT-registered businesses can normally reclaim 50% of the VAT on qualifying car rentals where private use is available, depending on circumstances and the normal VAT rules. Full rental-VAT recovery requires exclusive business use with no private availability. Maintenance can fall outside the rental block when it is genuinely optional, separately described in the contract and separately quantified on the invoice; recovery remains subject to normal VAT rules. Read HMRC’s motoring VAT guidance.
Businesses using the VAT Flat Rate Scheme do not normally recover input VAT on recurring car hire. The separate capital-goods exception does not turn hire invoices into a vehicle purchase. Check HMRC’s Flat Rate Scheme guidance.
The hire-cost rules normally disallow 15% of otherwise deductible rentals for cars above 50 g/km, subject to their scope and exceptions. A company-car BiK easement does not establish relief from this restriction. Check HMRC’s car-hire deduction rules.
For accounting periods beginning on or after 1 January 2026, revised FRS 102 generally requires a right-of-use asset and lease liability for lessees, including small companies using Section 1A. FRS 105 lease accounting for eligible micro-entities was not changed in the same way. Contract hire therefore does not universally keep a car off the balance sheet. Ask your accountant to apply the right framework; HMRC summarises the accounting standards.
A private Seal driver and a household needing the load opening of Seal 6 Touring have different requirements, even where the names look closely related. Try rear access with the passengers who will travel and check the luggage you normally carry. The saloon’s boot opening and an estate’s tailgate are practical differences that a capacity number alone cannot settle.
With Sealion 7, judge the roofline from inside the rear cabin as well as outside. Do not infer seven seats from the name. For smaller cars, compare Dolphin Surf and Dolphin using the actual seating and battery specification; they are distinct models. PCH does not use company-car BiK as the household cost measure. Include insurance, charging or fuel, maintenance and the proposed mileage allowance alongside the contract before deciding which body and drivetrain fit.
An electric BYD and a DM-i plug-in hybrid need different tax inputs. The table is a set of conditional benchmarks, not rates assigned across the brand.
For an employee or director with private use, the taxable benefit normally starts with the car’s P11D value multiplied by the applicable BiK percentage. Personal tax then depends on the individual’s income tax rate and any relevant adjustments. The percentage is not the tax rate applied to the lease rental. A sole trader’s own business car use follows different rules.
The agreement can cross several tax years. Compare the whole path, not just the percentage in the year the car arrives.
| Tax specification | 2026/27 | 2027/28 | 2028/29 | 2029/30 |
|---|---|---|---|---|
| Zero-emission electric car | 4% | 5% | 7% | 9% |
| Qualifying PHEV: 1-50 g/km; certified electric range 40-69 miles | 10% | 11% | 18% | 19% |
| Qualifying PHEV: 1-50 g/km; certified electric range 70-129 miles | 7% | 8% | 18% | 19% |
| Maximum petrol / qualifying diesel band | 37% | 37% | 38% | 39% |
These are conditional tax bands, not assigned rates for every BYD. Confirm the supplied car’s P11D, certified CO2, fuel type and registration date. Diesel supplements can apply where the required emissions certification is absent, subject to the annual maximum.
The electric-mile figures above are HMRC band thresholds, not promises of this car’s driving range. Newer plug-in hybrid certification can show more than 50 g/km. A temporary company-car easement may treat an eligible car as 1 g/km where the registration date, electric range and Euro-status conditions are met; it is not automatic and must not be transferred to lease-rental deductions. Check the vehicle documents and HMRC’s plug-in hybrid conditions with your accountant.
Use our company-car BiK guide alongside HMRC’s 2026/27 and 2027/28 tables and the published 2028/29 and 2029/30 changes. Tax information checked 24 September 2026 against the C1 ledger and its primary sources. Tax treatment depends on individual circumstances and may change; consult your accountant.
Vehicle Excise Duty (VED). For 2026/27, the standard annual VED payment after the first year is £200 before any supplement. First-year VED depends on CO2 and registration rules; zero-emission cars currently have a £10 first-year rate. These cash rates apply to 2026/27 only; later annual VED rates are not confirmed here. Ask how the funder treats tax increases during your agreement.
Expensive Car Supplement. The Expensive Car Supplement is currently £440 a year for five years from the second licence. The list-price threshold is more than £40,000 for petrol, diesel and hybrid cars, or more than £50,000 for qualifying zero-emission cars registered from 1 April 2025. Use the published list price before discounts, including relevant options, and check the registration date. Plug-in hybrids do not receive the electric-car threshold. GOV.UK explains VED and the supplement.
Planned eVED. The government plans Electric Vehicle Excise Duty (eVED) from April 2028, alongside VED: 3p per mile for electric cars and 1.5p per mile for plug-in hybrids. This is proposed for April 2028, subject to legislation and implementation; it is not a charge currently in force. The stated rates are planned starting rates, with CPI uprating proposed from 2029/30 and later cash rates not confirmed. An agreement spanning introduction needs the funder’s written treatment of the charge and later changes. Check the government’s consultation response and final implementation guidance before committing.
BYD builds its Blade Battery technology into its product story, but that does not give every car identical capacity or charging capability. The useful quotation identifies model year, battery, motor, wheels and fitted charging equipment. ATTO 3 EVO information should not be used to describe an earlier ATTO 3. Likewise, a Sealion 7 benchmark is not evidence for Seal U DM-i.
For routine use, establish how often the car can charge where it is normally parked. On longer trips, check compatible chargers and a realistic backup stop rather than planning to arrive empty at a single site. Published WLTP figures describe a test comparison; winter motorway use with passengers can produce a different result. Peak charging power is a maximum under suitable conditions, not a constant speed across the whole session. Battery temperature and arrival charge help determine the actual stop. Ask for any quoted range or charging time to be tied to the exact offered derivative.
BYD UK publishes basic vehicle coverage of six years or 150,000 km, expressed on its UK page as 93,750 miles, subject to the policy. Read the actual warranty for the supplied vehicle and its registration date. Battery and electric-drive cover use separate terms, so neither the vehicle headline nor another model’s battery promise should be applied to every component.
Before agreeing a high-mileage contract, identify the servicing location and the schedule for the exact electric or DM-i version. An engine-equipped plug-in hybrid and a pure EV need different maintenance planning. Ask which servicing and tyre costs the proposed maintenance arrangement includes, how repairs are authorised and what exclusions apply. A manufacturer remedy for an eligible defect is different from paying for routine wear, accidental damage or funder return charges. Include the time involved in reaching an authorised repairer in the decision, particularly if the car is essential for daily business travel.
Tell IVF your annual mileage, regular passengers, essential equipment, charging access where relevant and preferred timing. Ask for the precise model year, derivative, options and registration status to be written into the quotation. The catalogue is a starting point; the offered vehicle and funder terms need confirmation.
Business Contract Hire is taken by the business; Personal Contract Hire is taken by the private individual. Both are subject to status and individual funder criteria. Compare the initial rental, term, mileage, maintenance and applicable fees on the same basis. An initial rental is part of the hire cost, not refundable security or ownership equity.
A manufacturer warranty starts under the supplied car’s warranty terms, normally from first registration. Its time and mileage limits may finish before your lease does. It is separate from optional servicing and tyre cover. Confirm maintenance inclusions, insurance responsibilities, tax provisions and early-termination terms before signing.
At the end of contract hire, return the vehicle; there is no contractual purchase option. Excess mileage, damage beyond the funder’s fair wear and tear standard, missing equipment or other contractual charges may still be payable. Check the return process before choosing your agreement.
Use business car leasing, personal contract hire, company-car tax guide, VAT on business leasing, request a callback, electric car leasing, Tesla leasing, Kia leasing, director's guide to company car leasing, UK vehicle finance and leasing statistics to narrow your choice or discuss a quotation.
First identify electric or DM-i, then the actual body and generation. Compare initial rental, regular rentals, term, mileage, maintenance and fees on equivalent terms. A newer ATTO 3 EVO or a Seal 6 Touring may differ materially from another similarly named BYD even before the contract is considered.
No. BYD’s UK range includes pure-electric models and DM-i plug-in hybrids. A DM-i has a petrol engine as well as a rechargeable battery. Its charging plan, servicing and certified company-car tax inputs differ from those of an electric BYD.
No. They are separate electric hatchback models. Dolphin G DM-i is another distinct route with a plug-in-hybrid drivetrain. Choose the required seating, body and powertrain first, then match battery and equipment to the specific UK car being quoted.
Seal is the electric saloon route. Seal 6 DM-i is a separate plug-in-hybrid family, with saloon and Touring bodies to assess. The shared name does not establish the same drivetrain, luggage opening, charging specification or tax treatment.
Assess it using the fuel consumption and journeys you would actually have. A plug-in hybrid can run using petrol, but regular charging is central to using its rechargeable electric capability. A combined-range headline does not establish efficient operation in your own uncharged routine.
Do not infer seat count from the model number. Treat Sealion 7 as its own electric SUV specification and confirm the fitted seating. If a third row is essential, make that a firm requirement before IVF compares alternatives.
No. Keep the two model routes and their generations separate. A current EVO battery, drivetrain or charging figure cannot be assigned to an earlier ATTO 3 without exact manufacturer confirmation for the supplied model year and derivative.
BYD UK publishes six years or 93,750 miles of basic vehicle coverage, subject to the policy. Obtain the actual vehicle, battery and drive-unit terms, start dates and limits. Scheduled servicing, tyres and optional funder maintenance are separate from cover for eligible defects.
IVF arranges BCH and PCH subject to status and individual funder criteria. Company use needs separate employer and driver tax analysis; personal leasing focuses on your household’s agreement and running costs. Contract hire ends with return, with no contractual purchase option.
Send the model and body, electric or DM-i preference, annual mileage, essential equipment and required timing. Include your charging arrangements and whether maintenance is wanted. IVF can then check a specific vehicle and funder proposal instead of comparing loosely defined model names.
Bring your passenger, journey and equipment requirements. We can help turn them into a clear vehicle and contract brief.
