Ranked #215 car in the UK · SUV (EV) · 970 units sold last year
The Mercedes EQS SUV is the all-electric luxury seven-seater - effectively the electric counterpart to the GLS, with a vast, hushed cabin and limousine-grade comfort. A big battery gives long range, and the optional third row makes it a genuine electric family flagship. It floats rather than handles, prioritising serenity and space, and as a used buy it offers a lot of luxury electric SUV - depreciation has been steep, which makes it good value.
WLTP
The short version
Forecourt score
Value 8 · Reliability 34 · Insurance 12
The Mercedes-Benz EQS SUV loses value faster than most cars and is dearer to run than most. Its MOT-based reliability is good, 70 out of 100, ahead of 34% of the cars we track. On three-year value retention it ranks better than 8% of models.
The Forecourt score blends how this car ranks against the catalogue on value retention, reliability and insurance cost (weighted 40/40/20). Higher is better; running cost is not yet folded in.

If you're a company-car driver
At 3% BIK, this would cost a 40% taxpayer about £147/month in company-car tax (£73/month at 20%) — one of the strongest cases for choosing an EV via salary sacrifice. Full BIK table below for context.
Best age to buy — around 2 years
A 2-year-old example loses roughly £18,350 a year — under half the £40,700 a one-year-old sheds. The steepest drop is behind it.
Uses current UK pump and home-charging prices (DESNZ weekly), typical-driver insurance and manufacturer service intervals. "Fuel per mile" is just the energy input — so an EV at ~9p and a diesel at ~22p make running-cost comparison direct. A guide; your own costs will vary.

How we estimate this
Indicative annual comprehensive premium estimates. The 'Typical' figure represents an average UK driver in each age band; Lower and Higher risk show the realistic spread driven by factors UK insurers legitimately price on (postcode, occupation, claims history, NCB, voluntary excess, modifications). Based on 10,000 miles/yr, £250 voluntary excess, and the no-claims bonus selected above. Always get individual quotes before buying.

Safety recalls
Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Mercedes-Benz EQS SUV, or your exact vehicle, has any outstanding recalls on the official DVSA service.
Check on GOV.UKOpens the Driver & Vehicle Standards Agency recall checker. Choose the make, model and year of manufacture — no registration needed.

Whole-car theft
Higher
Desirable SUVs like this are relay-theft targets — keyless entry can be exploited from the driveway in under a minute.
Parts theft
Lower
As an electric car it has no catalytic converter, so the most common parts-theft vector doesn't apply.
Worth doing
Whether driving a Mercedes-Benz EQS SUV into a UK clean-air zone will cost you anything. Rules use the same Euro standard across most zones — petrol from 2006 and diesel from 2015 onwards are exempt; pure electric is always exempt.
| City | Area | Daily charge | Likely outcome |
|---|---|---|---|
| London | All of Greater London (within the M25) | £12.50 | Likely exempt Battery-electric — exempt everywhere. |
| Birmingham | Inside the A4540 Middleway | £8.00 | Likely exempt Battery-electric — exempt everywhere. |
| Bristol | City centre and part of the Portway | £9.00 | Likely exempt Battery-electric — exempt everywhere. |
| Glasgow | City centre | — | Likely exempt Battery-electric — exempt everywhere. |
| Edinburgh | City centre | — | Likely exempt Battery-electric — exempt everywhere. |

Winter range estimates assume ~5°C ambient with cabin heating; figures from manufacturer cold-weather testing where available, otherwise derived as a fraction of WLTP. DC times are manufacturer-claimed 10–80% on the headline charger; real-world sessions on UK rapids can be slower. Charging cost is a full battery at the home/blended electricity rate; public rapid charging costs more.
UK charging network
As of 2026-04-01, the UK has 119,080 publicly available EV chargers, up 12.6% on the prior year (13,281 added in 2025). 23% of those are rapid (50 kW+) or ultra-rapid (150 kW+), so the network can support both home and on-route charging.

What HMRC's Benefit-in-Kind charge looks like if you ran this Mercedes-Benz EQS SUV as a company car, by tax year and income-tax band. Calculated from a CO₂ of 0 g/km, using £146,500 as the P11D value.
EVs sit at the bottom BIK band — currently 3% — so this is one of the cheapest ways to take a company car.
| Tax year | BIK % | Tax @ 20% | Tax @ 40% | Monthly @ 20% | Monthly @ 40% |
|---|---|---|---|---|---|
| 2025-26 | 3% | £879 | £1,758 | £73 | £147 |
| 2026-27 | 4% | £1,172 | £2,344 | £98 | £195 |
| 2027-28 | 5% | £1,465 | £2,930 | £122 | £244 |
| 2028-29 | 7% | £2,051 | £4,102 | £171 | £342 |
| 2029-30 | 9% | £2,637 | £5,274 | £220 | £440 |
P11D value is approximated from the latest new price; the exact figure on your tax code will depend on options fitted. The 4% diesel surcharge applies only to non-RDE2 (pre-2021) diesels — we assume RDE2 compliance for current models. Bands and rates from HMRC's Autumn Budget 2024 confirmation through 2029/30.

Network size relative to the UK's largest (Mercedes-Benz is 2.8% of all franchised outlets)
Servicing, parts and warranty work are easy to find UK-wide, and most independent garages know the brand well — which keeps maintenance competitive.
For context, the UK has roughly 4,500 franchised car-dealer outlets in total, plus about 15,500 independent garages.
