BYD Seal U DM-i Comfort vs Škoda Kodiaq iV SE L: which five-seat UK PHEV suits your family?

BYD calls the Seal U DM-i its most popular UK model in its October 2026 sales release. That is a manufacturer statement, not an audited ranking of every Chinese plug-in vehicle. Our UK Search Console export for 18 September-15 October 2026 recorded 298 impressions for the exact query ‘byd seal u’ pointing to a buyer guide, with other Seal U queries also present. A UK comparison search result explicitly pits the Seal U against the Kodiaq; these are signals for a family-SUV buying question, not proof of search volume for this exact pair. Both cars are offered locally as five-seat plug-in hybrids. The important question is whether a lower entry price and longer warranty outweigh a much larger boot and stronger towing figure.

The comparison is the 2026 BYD Seal U DM-i Comfort front-drive PHEV against the UK Škoda Kodiaq SE L five-seat 1.5 TSI iV 204 PS DSG. Lookers shows a £36,995 BYD RRP and £34,991.02 cash offer for one listed car; this is a retailer-specific offer, not a nationwide guaranteed cash price. Škoda’s live range page shows the five-seat SE L from £45,185, a trim starting figure, so colour, options, location and final retailer quote still matter. At those displayed starting figures the gap is £8,190; compare itemised drive-away quotes and current stock before treating it as a saving. The Kodiaq SE L seven-seater on the same page is a different petrol/diesel specification; the iV here has five seats only. Do not use a seven-seat Kodiaq advert to promise seven seats in this PHEV.

The BYD measures 4,775 mm long and offers 425 litres with the rear seats up, 1,440 litres folded. Škoda gives its five-seat Kodiaq PHEV 745 litres seats up and 1,945 folded. The 320-litre seats-up advantage is material if you travel with a pram, a dog and bags together, but a boot-size standard does not reveal whether your particular buggy fits under the parcel shelf: bring it to both cars. The UK Škoda brochure lists 1,800 kg braked towing for the SE L iV; the listed BYD Comfort states 750 kg. That is a real distinction for a caravan buyer, subject to towbar approval, nose weight, licence and the actual vehicle’s plate. The BYD is not a seven-seat alternative, and neither is this iV.

The listed BYD Comfort is a 218 PS front-drive plug-in hybrid; Škoda specifies 204 PS for the front-drive iV and 0-62 mph in 8.4 seconds. Those headline figures are not a controlled same-day acceleration test. Battery charge, passenger load and a wet road will change response. For a family test drive, take both through the same motorway merge, rough road and tight parking route, and check rear-seat access with a child seat fitted. Škoda’s more conventional dashboard controls and BYD’s large screen are interface preferences; confirm the exact car’s equipment in person rather than importing a Boost or Design equipment table into Comfort.

Lookers quotes 77 miles WLTP combined equivalent all-electric range and a 26.6 kWh battery for this Comfort. Škoda’s UK range page confirms the 204 PS iV five-seat powertrain but gives a broad model range, not a trim-and-wheel-specific electric-mile line that we can tie confidently to SE L. Škoda’s 2026 UK brochure publishes up to 76 miles for the model family, so both can cover many ordinary commutes on paper; do not read one mile of apparent difference as a road-test win. Ask both dealers for the exact certificate of conformity or current WLTP line for the two cars quoted. In winter, at motorway speed or under load, expect less than laboratory range. A charge-sustaining petrol run is a separate cost scenario from WLTP weighted consumption, which assumes charging.

The BYD listing gives six years or 93,750 miles of vehicle cover and eight years or 125,000 miles of battery cover, with a 70% capacity threshold shown in its specification. Škoda UK states two unlimited-mileage years followed by a third year up to 60,000 miles; its PHEV high-voltage battery policy provides eight years or 100,000 miles against qualifying defects, with separate degradation terms. These are different contracts, not just two year-counts. Obtain the full exclusions, service intervals, courtesy-car rules and a named authorised workshop near home before ordering. A longer warranty does not offset an inconvenient service network for every buyer; conversely the Škoda boot does not offset a higher purchase price for a low-mileage household.

At the displayed list/starting prices the Škoda asks £8,190 more up front. The BYD dealer’s £34,991.02 cash offer is a separate, vehicle-specific price; its 49-month PCP example says £409 a month after a £2,999 customer deposit and an optional £13,261.50 final payment, with £36,707.69 total payable. A monthly figure alone therefore hides the deposit, mileage limit and balloon payment. We found no verified, same-date Škoda SE L PCP quote for this exact order, so there is no fair monthly-payment winner. For running cost, count home electricity used for regular commuting, then petrol on the miles beyond electric range; add insurance quotes, VED under the registration date, servicing, tyres and depreciation. The BYD dealer publishes 5.6 L/100 km WLTP charge-sustaining combined for this Comfort; Škoda’s prominently displayed weighted mpg assumes charging and cannot be compared directly with that depleted-battery figure. Ask for equivalent charge-sustaining data or use a realistic route log before declaring one cheaper to fuel.

Research checked on 26 October 2026 for the UK. The local demand signal is CathayEV UK Search Console query exposure from 18 September to 15 October 2026: the exact ‘byd seal u’ query has 298 impressions and zero clicks to one buyer guide. That is this site’s exposure, not monthly UK search volume or a measured count for ‘Seal U versus Kodiaq’. BYD’s October UK sales statement supports model popularity, but it does not establish a cross-brand China-EV Top 10 position. The retailer listing establishes one Comfort offer and specifications; the Škoda UK range page establishes the live five-seat SE L. We have not driven either car, measured fuel economy, obtained like-for-like insurance quotes, or verified current household charging prices. Euro NCAP assessments cover the named variants but different test years. Recheck price, trim certificate and warranty terms before deposit.
