One-liner
An automated tax calculator providing proactive, multi-year projections for UK EV buyers to navigate complex and changing vehicle excise duty, including the upcoming pay-per-mile eVED.
The Pain
UK drivers, especially EV owners/buyers, struggle with the complex, frequently changing Vehicle Excise Duty (VED) rules. This includes understanding new EV tax bands, the luxury car supplement, and anticipating future costs like the pay-per-mile eVED system, leading to financial uncertainty before and after purchase.
The Gap
Current free tools only offer reactive, 'current tax' lookups. Paid APIs are for businesses. There is a clear lack of consumer-facing tools that provide proactive, multi-year tax projections and scenario planning for the evolving UK EV tax landscape.
Build Angle
Develop a user-friendly web application that allows UK drivers to input vehicle specifications and receive accurate, multi-year projections of their VED liability for electric vehicles, specifically addressing new bands, luxury car supplements, and estimated eVED costs. Start with an MVP focused on pre-purchase tax estimates for popular EV models.
Reasoning
This idea scores highly across all lenses because it addresses a significant, growing financial pain point for a specific, identifiable audience. The market is evolving rapidly with new regulations, creating a sustained demand for clarity that existing tools don't provide. A solo builder can carve out a strong niche by offering proactive, accurate tax projections for EV buyers. While ongoing data maintenance is a consideration, the strong market signals and clear monetization path make this an excellent candidate for a solo builder's weekend and beyond. The composite score of 81 reflects high confidence, well above the 65 threshold for crowded markets, as this targets a specific unserved need within a growing market.
Risks
Pricing Landscape
Existing solutions for vehicle tax calculation in the UK generally fall into two categories: free online calculators provided by automotive websites and paid API services for businesses. The free calculators typically require a vehicle registration number to provide current VED costs and expiry dates, drawing data directly from the DVLA. These free tools do not usually offer in-depth projections for future tax changes or complex scenarios like the luxury car supplement for EVs. For businesses, several companies offer APIs that provide comprehensive vehicle data, including tax information, MOT history, and specifications. These are typically priced through subscriptions or per-query models, with specific pricing not publicly disclosed without direct inquiry, but one API offers a free tier with a limit of 1 request per second. The DVLA also provides a Vehicle Enquiry Service API for commercial customers. The introduction of the pay-per-mile eVED is prompting the development of new calculators, some of which are free and estimate annual costs based on mileage. Annual VED rates are currently around £200 for most cars after the first year (rising from £195 in 2025/26), with an additional £440 for five years for 'expensive cars' (list price over £40,000, or £50,000 for EVs from April 2026).

Market Signals
The market for automated tax calculation for vehicle ownership changes in the UK is growing due to recent and upcoming significant changes to Vehicle Excise Duty (VED), particularly for electric vehicles (EVs). Historically, EVs were exempt from VED, but this changed in April 2025. Now, all EVs pay a first-year rate and then a standard annual rate. The introduction of a pay-per-mile 'eVED' system for EVs and PHEVs from April 2028 further complicates the tax landscape, making tools that clarify these costs increasingly valuable. Fuel duty and VED combined generated approximately £32 billion in the 2023/2024 fiscal year, indicating a large overall motoring taxation market.
