Used BYD Seal Cars for Sale at Vertu
The BYD Seal is one of the most compelling second-hand electric cars available in the UK - a full-size all-electric saloon that arrived in 2023 to take on the Tesla Model 3.
With up to 354 miles of WLTP range and a Euro NCAP five-star rating, it's a serious proposition. Buying used puts you behind the wheel for less - and on a BYD this young, that saving is substantial.
Every used BYD Seal at Vertu has been prepared to our standard. Our colleagues are ready to help you choose the right example for your needs. Browse current used BYD cars or read on to understand exactly what the Seal offers.
The Seal is available in six exterior colours: Space Black, Ice Blue, Atlantis Grey, Polar White, and the optional Shadow Green and Indigo Grey - with a choice of Black or Tahiti Blue interior.
Why Buy a Used BYD Seal?
Electric vehicles depreciate faster in the early years than petrol equivalents. That pattern works in your favour when buying used - a used BYD Seal delivers the same performance, charging capability, and technology as a new one, at a significantly lower cost.
The more compelling reason to buy used is what stays with the car. BYD backs every Seal with a 6-year vehicle warranty and an 8-year Blade Battery and motor warranty. A 2023-registered used BYD Seal could carry five or more years of manufacturer cover.
The Blade Battery itself adds further reassurance - it uses LFP (Lithium Iron Phosphate) chemistry, which handles more charge cycles with less degradation than the NMC batteries found in many rivals. Cold resistance, thermal stability, and longevity are genuine strengths of LFP, giving drivers unparalleled reassurance.
Who Is the Used BYD Seal Best For?
The Seal suits customers who want the interior space and road presence of an executive saloon without paying executive saloon running costs. With zero tailpipe emissions whilst driving and low electricity costs, it's a credible alternative to a used BMW 3 Series, Mercedes C-Class, or Audi A4 for anyone whose annual mileage makes fuel savings count.
It also makes a strong case for first-time EV buyers stepping up from a smaller electric car. The 354-mile range of the Design trim removes any anxiety about long runs. Home charging on an 11 kW wallbox keeps costs low and routines simple. And the heat pump, standard on both trims, preserves that range in cold weather - a detail that matters on British roads in winter.
Fleet-cycle and ex-demonstrator examples are worth seeking out specifically. Low-mileage cars from this source often retain most of their remaining warranty. Our colleagues at Vertu can confirm remaining warranty cover on any individual car before you commit.
Design or Excellence: Which Used BYD Seal Should You Choose?
The BYD Seal is available in two variants. Both use the same 82.5 kWh Blade Battery and share the same charging capability. The choice comes down to what matters most to you on the road.
Design (RWD): the single-motor, rear-wheel drive version, hitting 0-62 mph in 5.9 seconds and a 354-mile WLTP range. This is the trim for customers who prioritise range and efficiency for everyday use. It also includes the 72-litre frunk, a convenient bonus for separating charging cables from luggage.
Excellence (AWD): the dual-motor, all-wheel drive version, boasting 0-62 mph in 3.8 seconds and a 323-mile range. The Excellence adds semi-active frequency-variable dampers on the rear suspension, which adjust continuously between smooth and rough surfaces. It suits customers who want saloon performance to match the saloon looks, or who regularly drive in conditions where the extra traction of AWD matters.
Both trims share the same comprehensive interior specification, including the rotatable 15.6-inch touchscreen, Dynaudio sound system, panoramic sunroof, and the full ADAS suite. Choose a Black interior for a clean, contemporary finish or Tahiti Blue for something genuinely distinctive - an interior colour option that sets the Seal apart from anything in the used German saloon segment.

Used BYD Seal Range and Running Costs
The 82.5 kWh Blade Battery is the same unit across Design and Excellence. In real-world UK driving, most owners report ranges that sit comfortably between 280 and 330 miles depending on speed, weather, and load - more than enough for a week of commutes between charges.
At home, the 11 kW AC on-board charger takes a near-flat battery to full overnight on a standard 7 kW wallbox. On the public network, 150 kW DC fast charging brings the battery from 30% to 80% in 26 minutes. The CCS2 charging port is compatible with every major UK rapid charging network.
Running costs are low in the way all BYD electric cars are: no fuel, no clutch, no cambelt, and servicing intervals that are simpler than any petrol equivalent. The LFP chemistry also means you can charge to 100% regularly without accelerating battery wear - unlike NMC batteries, which benefit from being kept below full charge.
The standard V2L (Vehicle-to-Load) function, available on both trims, lets you draw up to 3,000W from the car's battery. That's enough to power camping equipment, tools on a job site, or appliances during a power cut.

Used BYD Seal: Frequently Asked Questions
Does the Blade Battery Degrade Over Time on a Used BYD Seal?
The Seal uses LFP (Lithium Iron Phosphate) chemistry in the Blade Battery - not the NMC chemistry found in many competitors. LFP is significantly more resistant to capacity loss over repeated charge cycles. It also tolerates regular 100% charging without the degradation penalty that affects NMC batteries.
BYD backs the battery and electric motor with an 8-year, 155,350-mile warranty. On a 2023-registered car, that cover runs until at least 2031. Our colleagues can confirm exact remaining warranty for any specific car in our stock.
Will a Used BYD Seal Hold Its Value?
Like most electric cars, the Seal depreciates more sharply in years one and two than comparable petrol cars. After that initial drop, residual values tend to stabilise - particularly on models with strong remaining warranty cover. The Seal's combination of long warranty, LFP battery durability, and a growing BYD UK dealer network all support its long-term position.
Buyers purchasing used today are entering at a point where the steepest depreciation has already occurred. The remaining manufacturer cover, Euro NCAP five-star rating, and strong specification relative to price make the used BYD Seal a considered choice in the used cars market.
What Does BYD Approved Used Cover on a Used BYD Seal?
BYD launched its Certified Pre-Owned programme across its UK dealer network in October 2025. Every BYD Certified Pre-Owned vehicle undergoes a 179-point inspection - covering technical performance, vehicle records, and condition - carried out with third-party involvement to ensure impartiality.
Approved used BYD cars include a minimum one-year vehicle warranty (20,000 km), the remaining balance of BYD's 8-year battery warranty up to 200,000 km (125,000 miles), and two years of 24/7 pan-European roadside assistance.
Ask our colleagues whether a specific used BYD Seal in our stock qualifies under the BYD Certified Pre-Owned programme.
What Finance Options Are Available on a Used BYD Seal from Vertu?
Used car finance works differently from new: agreements are typically shorter, and the structure varies by the age and value of the car. Vertu can introduce you to a range of lenders to find an option that fits your budget.
PCP (Personal Contract Purchase) and HP (Hire Purchase) are both available on eligible used cars. PCP gives you flexibility at the end of the term; HP gives you a clear route to owning the car outright. To discuss BYD prices and get a personalised finance illustration, contact your nearest Vertu BYD dealership.

Vertu operates BYD dealerships at five UK locations: Vertu BYD Worcester, Vertu BYD Macclesfield, Vertu BYD Hartlepool, Vertu BYD Gloucester, and Vertu BYD Morpeth. All sites stock used BYD cars and have trained colleagues on hand to assist.
