Ioniq 5 vs Model 3 Running Costs in the UK: 3-Year Real Math
Insurance, home charging, public charging, tyres, and depreciation side-by-side for UK buyers comparing Hyundai Ioniq 5 and Tesla Model 3.
UK buyers cross-shop the Hyundai Ioniq 5 and Tesla Model 3 constantly. Purchase price tells half the story. This comparison models three-year running costs for a driver covering 10,000 miles per year with mostly home charging.
Purchase price snapshot (2027–28)
Both models qualify for varying UK incentives depending on trim and battery size. Check current OZEV guidance before buying — rules change.
Typical on-the-road spreads: - Tesla Model 3 RWD: lower entry price, strong Supercharger network access - Hyundai Ioniq 5: often higher list price but aggressive finance offers
Insurance
Insurance groups vary by trim. Young drivers pay sharply more on either model. Compare quotes before purchase — a £200/year difference equals £600 over three years.
Model 3 Performance trims cost more to insure than Ioniq 5 Premium AWD in most UK postcodes we sampled.
Charging costs
Home (Octopus Intelligent / similar off-peak): ~£0.07–0.09/kWh effective → roughly £350–450/year for 10k miles on either car.
Public rapid charging only: costs can exceed petrol for heavy motorway users. Neither car is cheap if you cannot charge at home.
Winner for motorway users: Model 3 — Supercharger reliability and routing integration reduce wasted time (time has value).
Tyres and servicing
EVs wear tyres faster due to weight. Budget £600–900 for a full set on either car. Tesla service intervals are minimal but out-of-warranty repairs at Tesla centres can be expensive. Hyundai dealer network is broader for non-warranty work.
Depreciation
Tesla Model 3 depreciation accelerated in 2027–28 as prices cut globally. Ioniq 5 depreciation is moderate for a premium EV. Over three years, assume 35–45% loss on either unless market conditions shift.
3-year total cost table (illustrative)
| Cost line | Model 3 RWD | Ioniq 5 AWD | |-----------|-------------|-------------| | Electricity (home-heavy) | ~£1,200 | ~£1,250 | | Insurance (mid-age driver) | ~£2,400 | ~£2,200 | | Tyres (one set) | ~£750 | ~£800 | | Servicing | ~£400 | ~£450 | | Depreciation | High variable | Moderate variable |
Who should buy which?
Model 3: you rely on Superchargers, want the best software/charging UX, and can charge at home overnight.
Ioniq 5: you want faster DC charging peaks, more rear space, and traditional dealer service outside Tesla centres.

Electricity, insurance, and tax
Home charging at 24p/kWh off-peak vs public 55–79p/kWh DC dominates pence-per-mile spread — Ioniq 5 and Model 3 efficiency similar (~3.5–4 mi/kWh real). Model 3 slightly more efficient highway; Ioniq 5 heavier but competitive in summer.
Insurance varies by postcode and theft stats — Model 3 historically higher in London; shop both annually. VED both zero for pure EV until policy changes — watch budget statements. Company car BIK still favours both versus petrol equivalents.
Maintenance and tyres
EV service intervals sparse — brake fluid, cabin filter, tyre rotation. Tesla mobile service convenient; Hyundai franchised network broader in northern UK. Tyres expensive on both — 20-inch rubber on Ioniq 5 GT-line budgets £800+ per set; Model 3 performance similarly hungry.
Warranty: Hyundai 5-year unlimited mileage vehicle warranty beats Tesla 4-year vehicle on today's market UK — battery warranties both long but terms differ on degradation thresholds. Used buyers compare SOH expectations.
Depreciation and charging network
Tesla Supercharger access and brand cachet slowed early depreciation; Ioniq 5 discounts from list faster — better used value, worse new buyer equity. Ioniq 800V charges faster on capable DC hardware when warm.
Total cost winner depends on purchase price paid — Ioniq 5 used at 40% off list often beats new Model 3 on three-year spreadsheet even with slightly higher kWh/100mi. Model 3 wins on software ecosystem and sparse-route Supercharger reliability.
Annual running cost snapshot
Typical UK mixed driving: £450–650/year electricity at home rates for 10k miles; add £200–400 if 40% public charging. Insurance £600–1,200 depending on postcode and driver age — Model 3 often upper band in cities. Tyres every 25–35k miles on heavy EVs — budget £700+ set. Service £150–300/year average — Tesla parts pricing varies by region.
Which is cheaper to run purely on public charging?** Neither shines — public-only users pay 2–3× home-charge cost per mile. Model 3 Supercharger membership pricing vs Ioniq on Ionity/Grid — map your routes.
Do both qualify for home charger grants?** Grant eligibility follows installer and property rules, not brand — see home charger amp guide for install sizing.
Which holds battery health better after five years?** Fleet data still accumulating — both generally report strong SOH with normal use. Avoid cars with exclusive DC-only fast-charge history.
FAQ
Is the Ioniq 5 cheaper to run than a Model 3 in the UK?** Home charging costs are similar. Insurance and depreciation often favour the Ioniq 5; Supercharger convenience favours Tesla for frequent long trips.
Do both qualify for home charger grants?** Grant rules change — verify current OZEV eligibility for your property and vehicle before ordering a charger.
Which is better for company car tax (BIK)?** Both can offer low BIK on electric models; compare exact CO₂ figures and list price for your tax band.
