A Number That Hasn't Moved Since 2010
The UK's statutory Class 4 MOT fee is capped by law at GBP54.85. It's been exactly that figure since 2010. For internal combustion vehicles, that fee cap has never really mattered much to garage economics. For electric vehicles, it's becoming a genuine structural problem.
How the Old Model Worked
Garages have always treated MOT testing as a loss-leader by design. The GBP54.85 fee rarely covers the true cost of inspection bay time and technician labour. What made that acceptable was the follow-on work an ICE inspection reliably surfaced -- a worn brake pad, a failing exhaust, a leaking gasket -- which became the actual revenue from the visit.
Why Electric Vehicles Break the Model
There's no exhaust to fail on a BEV. No timing belt to flag. Regenerative braking cuts friction-brake wear dramatically. The MOT visit that used to reliably generate a follow-on repair ticket for an ICE vehicle increasingly just ends, for an EV, once the tyres and suspension bushes have been checked. Independent garages performing EV MOTs are absorbing a genuine, structural loss on a statutory obligation they can't decline to offer and can't reprice upward themselves.
The Industry's Own Response
The Independent Garage Association has petitioned the Department for Transport directly to review the fee cap, presenting documented evidence that 16 years of cumulative workshop inflation across technician wages, diagnostic licenses and electricity overheads have turned statutory EV MOT testing into a break-even or loss-leading activity without associated repair work to offset it.
A Named Comparison: Why This Squeeze Is Specific to EVs, Not Garages in General
It would be easy to read this as a generic story about garage margins under inflation pressure. It's more specific than that: ICE garages facing the same 60%-plus overhead inflation still have the mechanical follow-on work available to absorb it. EV garages face the identical fee cap and the identical overhead inflation, but without the offsetting revenue stream ICE garages have always relied on. The squeeze is genuinely EV-specific, not a general statement about UK garage economics.
The Scale This Problem Reaches Across the Sector
This is not a handful of garages absorbing a minor inconvenience. Every independent shop performing statutory EV inspections nationwide faces the same fixed fee and the same eroded follow-on revenue, meaning the structural loss compounds across the entire independent sector rather than concentrating in a few unlucky locations.
What This Means for Independent Garages and Policymakers
The practical takeaway: independent garages weighing whether to actively pursue or quietly deprioritize EV MOT testing volume should factor in that this specific statutory test, absent a fee cap review, does not pay for itself on electric vehicles the way it has always done on combustion ones — and should plan pricing and service-bundle strategy around that reality rather than assuming historic ICE economics will carry over.
