The UK's planned ban on new petrol and diesel car sales has been one of the most-changed policies of the past decade. Announced for 2030 in 2020, pushed back to 2035 in September 2023, then reverted to 2030 by the Labour government in 2024-2025. As of May 2026 the policy is settled (for now) but widely misunderstood. This guide explains exactly what's been confirmed, what it means for Cornwall drivers, and what to plan for if you currently drive a petrol or diesel car.

The current state of the policy (May 2026)

Under the Labour government, the UK has reinstated a two-step phase-out:

  • From 2030: No new pure-petrol or pure-diesel cars sold in the UK
  • 2030-2035: Plug-in Hybrids (PHEVs) and certain Full Hybrids (HEVs) can still be sold, provided they meet "significant zero-emission range" requirements
  • From 2035: All new cars and vans sold in the UK must be 100% zero-emission at the tailpipe

This applies to new car sales only. Existing petrol and diesel cars remain perfectly legal to drive, sell, and buy used. There are no current plans to make ICE driving illegal after 2030 or 2035.

What's confirmed and what's still being legislated

The ZEV Mandate (Zero Emission Vehicle mandate) is already in force, requiring manufacturers to sell increasing percentages of electric vehicles each year. The 2026 target is 28% of new car sales; rising to 80% by 2030 and 100% by 2035. The mandate is enforceable today.

The 2030 ban itself is largely the inevitable consequence of the ZEV mandate — manufacturers can't sell ICE cars if they'd breach the mandate. Specific legislation may still be refined, but the direction is now settled bipartisan policy.

What this means for Cornwall drivers

If you currently drive a petrol or diesel car

Nothing changes immediately. You can:

  • Continue driving your car indefinitely
  • Buy and sell used petrol/diesel cars after 2030 and 2035
  • Service and maintain ICE cars (servicing capacity will remain)
  • Buy fuel — petrol stations will remain operational for many years post-2030, though numbers gradually decline

If you're planning to buy a new car in 2026-2030

You have full choice — petrol, diesel, hybrid, EV, plug-in hybrid. After 2030, your options shift toward hybrids and EVs only. Beyond 2035, only EVs (or hydrogen, very niche).

If you plan to keep a car for 10+ years, buying a new ICE in 2028 means driving it through to 2038 — which is fine for normal use, but resale value may be impacted as the used market shifts toward EVs.

If you're planning to buy an EV or hybrid

Good timing. EV prices are falling, model choice is broad (60+ UK-market EVs in 2026), and charging infrastructure is rapidly expanding — including in Cornwall (see our Cornwall public charging guide).

Will Cornwall's roads change?

Slowly. Cornwall's car parc (the total of cars on the road) in 2026 is ~500,000 vehicles. Of these, about 10% (50,000) are EVs and PHEVs; the rest are ICE. As new sales shift toward EV-only:

  • By 2030, around 20-25% of Cornwall cars likely EV/PHEV
  • By 2035, around 40-50%
  • By 2040, around 65-75%
  • By 2045, ICE cars become rare on Cornwall roads (collectors, classics, specialist use)

The transition is gradual. Don't panic-sell your reliable diesel estate.

What about driving costs after 2030?

Several Cornwall-specific factors to consider:

  • Fuel duty: Successive governments have signalled increased fuel duty post-2030 to maintain tax revenue as the EV share grows. Expect petrol/diesel running costs to rise faster than RPI.
  • Road pricing / pay-per-mile: Possible introduction post-2030 to replace fuel duty revenue. May affect EV drivers and ICE drivers differently.
  • ULEZ-style zones: Cornwall is unlikely to see ULEZ-style zones in the near term (too dispersed), but Bristol, Plymouth, and Exeter (Cornwall's gateway cities) have or are considering Clean Air Zones.
  • Insurance: ICE insurance may rise faster than EV insurance from 2030 onward as the ICE pool shrinks.
  • Servicing: Gradual closure of dealer service capacity for ICE in late 2030s; independent mechanics will remain.

What about caravans, motorhomes, and classics?

  • Caravans / trailers: Towed by EV — increasingly viable but tow capacity and battery range need consideration. Tesla Model Y can tow 1,600kg; many EVs are lower. Specific touring use cases require careful EV selection.
  • Motorhomes: Electric motorhome market is nascent. Pure-electric motorhomes available but limited; PHEV motorhomes more common. Plenty of range / weight challenges.
  • Classic cars: Not affected. The 2030 ban applies to new car sales only. Classics, vintage, and used ICE remain legal indefinitely.
  • Commercial vehicles / vans: Vans follow the same 2030/2035 timeline. Electric vans are increasingly available; the Cornwall trade industries (plumbers, electricians, builders) will transition gradually.

What Cornwall holiday-business owners need to plan for

  • By 2028: EV charging will likely be a baseline expectation at holiday lets, hotels, and B&Bs. See our holiday let guide.
  • By 2030: Customer-visiting businesses (restaurants, attractions, retail) increasingly differentiate via EV charging facilities.
  • By 2035: EV charging is universal infrastructure, expected like wifi or parking.

Adding chargers now (with the £500 OZEV/WCS grant) costs less and starts the payback earlier.

The bigger picture: should you switch to an EV in 2026?

For most Cornwall drivers, the economic case for EV ownership is now strong:

  • EV running costs (charging at home): 1-2p/mile vs 13-15p/mile for petrol
  • Home charger install: £800-£1,200 (or £450-£800 with OZEV grant if eligible)
  • EV depreciation: still high in years 1-3 but stabilising
  • Cornwall's public charging network: now adequate for most use cases

The trickiest cases:

  • No driveway: harder but not impossible (see no-driveway guide)
  • Very high annual mileage (40,000+): EV economics get better, but consider battery degradation
  • Towing-dependent (caravan, trailer): check specific EV tow ratings carefully
  • Off-grid rural: still feasible but plan charging carefully
