BYD Sealion 5 Leasing

Your BYD Sealion 5 leasing decision

Intelligent Vehicle Finance helps you compare BYD Sealion 5 DM-i leasing, including Design. This UK family SUV is a petrol plug-in hybrid, not the electric Sealion 7. Comfort and Design appear in IVF’s September 2026 listings; choose around charging access, family use and the supplied car’s certified tax specification.

Sealion 5 Design leasing: a battery choice as well as equipment

A Design enquiry should begin with how the car will be charged and used, not just the features it adds. BYD gives Design a larger battery than Comfort as well as additional equipment. That makes the comparison relevant to a household with regular local journeys and a business driver whose working week includes longer trips. Ask for both versions on the same contract assumptions if you are undecided.

Our positioning is straightforward: consider Sealion 5 when you want a family SUV and can make practical use of a plug-in hybrid. Look elsewhere if your priority is a fully electric car or if the parking space makes a vehicle of this length awkward. The Sealion name does not make it the same product as Sealion 7, and a numerical model badge is not an equipment hierarchy.

BYD Sealion 5 leasing: key facts

• BYD UK launched Sealion 5 as a DM-i petrol plug-in hybrid; it is separate from the electric Sealion 7.
• Comfort uses a 12.96 kWh battery and Design an 18.3 kWh battery in the UK manufacturer reference.
• BYD’s UK dimensions are 4,738 mm long, 1,860 mm wide and 1,710 mm high; check mirrors and parking clearance separately.
• The UK reference describes five seats and a 463-litre boot with the rear seats raised.
• IVF lists 1.5 DM-i Comfort and 1.5 DM-i Design, both five-door automatic SUV descriptions.
• GOV.UK: the maximum company-car BiK band is 37% in 2026/27 and 39% in 2029/30; the exact car can fall in a lower band.

Compare the BYD Sealion 5 options

These are different vehicle choices, not an equipment ranking. Compare the exact specification and the same contract assumptions.

UK status and the two IVF catalogue versions

BYD's UK press office announced the Sealion 5 in January 2026, and current UK model material describes Comfort and Design. IVF's live route lists both as 1.5 DM-i automatic SUVs. Those sources establish the model and catalogue coverage; they do not establish that a particular colour or derivative has an allocation available through IVF today.

Have the model year and the complete derivative confirmed when a proposal is prepared. Manufacturer pages can retain launch descriptions while current vehicle documentation changes. If a feature is essential, name it in the brief and check it against the supplied car. Avoid treating a photograph, an equipment shorthand or the Design name alone as contractual confirmation.

Comfort versus Design in a working family week

Comfort is the starting point for assessing whether the basic cabin and plug-in hybrid format meet your needs. Design changes the battery specification and adds items identified by BYD UK, including a surrounding-view camera, powered tailgate and heated front seats. Decide which of those additions you would use repeatedly. A tailgate can help with loading, but it does not change whether the normal family luggage fits.

The battery difference deserves its own calculation. Estimate the trips between realistic charging opportunities, including school runs, client visits and evening travel, rather than relying on a commute alone. Then request the combined electric-range certification for the exact vehicle. The larger battery may change the proportion of journeys that can be planned around electricity; it does not create a fixed petrol saving for every driver.

What DM-i means for charging and fuel

Sealion 5 DM-i has a petrol engine as well as a battery that can be charged externally. It can therefore support a different travel pattern from an electric-only SUV. However, the purpose of the plug should remain part of the decision. If you expect to leave the car uncharged most of the time, assess the operating costs on that basis rather than borrowing a weighted consumption headline.

Check the car's own charging capability before buying equipment or planning stops. The UK reference lists AC charging for Sealion 5; do not assume that a rapid-charging feature discussed for another BYD applies here. Home parking, the cable route and the available electrical supply determine whether charging becomes a routine task or a repeated inconvenience. A competent installer can advise on the property requirements.

Check access and luggage with the seats in use

Measure where the SUV will live, allowing for mirrors, doors and the tailgate. A parking camera is assistance, not a way to create space that is absent. If someone has difficulty with entry, try the actual seat height and door opening. Do the same with any child restraints using the manufacturer's instructions, rather than judging the cabin from its seating total alone.

Load the items that travel together. A pushchair, overnight bags and work equipment can be a different challenge from a single large suitcase. The rear-seats-up boot reference is the relevant starting point when all passenger positions are needed. Folding seats only helps on journeys where the corresponding passenger space is spare. Check visibility and safe load restraint as well as volume.

Sealion 7 and Seal U clarify two different alternatives

Sealion 7 is the relevant BYD comparison if you would prefer to remove petrol from the brief and use a fully electric SUV. That changes the charging and tax assessment, so compare the actual journey pattern again. Do not transfer the Sealion 5 battery, luggage or charging specifications to the similarly named electric car.

Seal U offers a separate plug-in hybrid SUV route. Its own versions and equipment need to be assessed independently; Design or Comfort labels should not be treated as a promise of matching hardware across model families. If the Sealion 5 fails a particular passenger or load test, repeat that same test in the alternative. This is more informative than comparing trim names in isolation.

The tax specification can make Comfort and Design different

A business should request the certified CO2 and electric range for the offered Sealion 5, not simply ask for a generic hybrid tax rate. The manufacturer's Comfort and Design references sit on different sides of some relevant thresholds. Newer emissions certification and the conditional HMRC plug-in hybrid easement make the registration details important too. Your accountant should assess the actual documents before you use a benefit figure.

BYD Sealion 5 company-car tax across the lease

Do not apply the zero-emission BiK band to Sealion 5. Its petrol plug-in hybrid specification requires a CO2 and electric-range assessment. Comfort and Design can create different company-car outcomes even when both are being quoted for the same business.

Use the offered car’s P11D and the applicable annual percentage to calculate the taxable benefit, then apply the driver’s income-tax circumstances. The lease rental is not the base for this calculation. The conditional bands below require the actual certified CO2 and electric range, or an eligible HMRC easement; they are not assigned automatically to catalogue entries.

These are conditional tax bands, not assigned rates for every BYD Sealion 5. Confirm the supplied car’s P11D, certified CO2, electric range and registration date. Where the qualifying conditions are not met, use the applicable CO2 band instead.

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.

Road tax and costs across the term

Vehicle Excise Duty (VED). Sealion 5 is a hybrid for road-tax purposes. Its first-year VED depends on certified CO2; the 2026/27 standard rate after year one is £200 before any supplement. Do not use the electric car’s first-year figure. Later annual rates and the funder’s treatment of increases need checking.

Expensive Car Supplement. The hybrid list-price threshold is more than £40,000, including relevant options before discounts. Where applicable, the 2026/27 Expensive Car Supplement is £440 per year for five years from the second licence. The £50,000 threshold for qualifying zero-emission cars does not apply to Sealion 5 DM-i.

Planned eVED. Planned eVED would add 1.5p per mile for plug-in hybrids from April 2028, alongside VED and fuel costs. It is not in force today and remains subject to legislation and implementation. CPI uprating is planned from 2029/30. Check how a Sealion 5 contract extending into that period handles the charge.

Check current GOV.UK road-tax rules and the government eVED consultation response. Tax treatment depends on circumstances; confirm the supplied car and consult your accountant.

VAT and the business accounts

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.

Build the quotation around the way you will use it

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.
