BYD Warranty*: Everything you need to know about BYD cover, battery protection and servicing

When investing in a new electric vehicle, one of the most important factors to consider is warranty coverage. BYD has quickly become one of the UK's fastest-growing EV brands, and its comprehensive warranty package helps give drivers confidence in long-term ownership.


In this guide, we will answer the most common questions about the BYD Warranty UK, including battery coverage, transferability, model-specific warranties and what owners can expect from BYD service and maintenance plans.


What warranty does BYD offer?

One of the most common questions from prospective buyers is, what warranty does BYD offer and How long is BYD warranty?

BYD provides one of the most comprehensive warranty packages available on a mainstream electric vehicle in the UK.

Current warranty coverage includes:

  • 6-year vehicle warranty (or up to 93,750 miles)
  • 8-year drive unit warranty
  • 8-year battery warranty
  • 6 years of roadside assistance
  • 12-year anti-perforation (corrosion) warranty

This combination helps protect owners against unexpected repair bills while supporting long-term EV ownership.

BYD Blade Battery Warranty

Every BYD EV uses the manufacturer's innovative Blade Battery technology. The BYD Blade Battery warranty provides reassurance for owners concerned about battery longevity, degradation and reliability.

BYD states that the Blade Battery has been engineered for a long operational life with more than 5,000 charge and discharge, helping support durability over many years of use.

BYD Service Requirements

To keep warranty protection active, owners should follow the recommended BYD service schedule. Reach out to our aftersales team to book in your service or find out when your next service is due. Missing services or carrying out repairs using non-approved parts could affect warranty eligibility.

Regular servicing also helps:

  • Maintain vehicle efficiency and performance
  • Identify issues early
  • Reduce long-term repair costs
  • Support future resale value
  • Increased vehicle lifespan

What isn't covered?

Like most manufactuers, BYD excludes items considered normal wear and tear.

Examples may include:

  • Tyres
  • Brake pads
  • Cosmetic damage
  • Damage caused by misuse or neglect
  • Non-approved modifications or parts

Owners should always review the official warranty handbook for full terms and exclusions.


Is BYD Warranty transferable?

Yes, one of the biggest ownership benefits is that the manufacturer's warranty is generally transferable to a new owner if the vehicle is sold

For used car buyers, this means a pre-owned BYD may still retain valuable manufacturer-backed coverage. For current owners, it can also help improve resale appeal when the time comes to upgrade.
