What is coming through the workshop door, read three years ahead.

Forward research for the UK independent garage trade, built entirely from public records. Current printing: August 2026.

How it can be known

A car's first MOT falls three years after registration, fixed in law, and registrations are public. Registered in 2025 means arriving in 2028. So the mix of cars reaching a first MOT, by fuel and by make, is on the record about three years before it arrives, and it can be read by region and by local authority as well as nationally.

The mechanism has been checked against seven years of actual MOT results, three times: on diesel, on electric cars, and on petrol, the one fuel that turns inside the window, where it called the turning point to the year. The booking system and the benchmarking tools describe the road behind. None of the operators interviewed for the report had a forward view built from that record, and none of the tools they named provides one. This is an attempt at one.

Line chart. Diesel share of cars reaching a first MOT, 2019 to 2025, from DVSA test records, plotted against new-car diesel registrations from three years earlier. The two lines fall together on the same schedule, from about 52% in 2019 to about 15% in 2025, with the arrivals line a few points above registrations because first MOTs include vans and used imports.
Diesel, the first check: what arrived for a first MOT each year against what new-car registrations three years earlier said would arrive. Sources: DVSA anonymised MOT results, test years 2019 to 2025; SMMT new-car registrations. From the August 2026 report.

The August 2026 report: six things already on the record

What's coming down the road: a forward look for the UK independent garage trade. Twenty-three pages, with the method, the sources and the limits of every figure, and a two-page summary. The headline readings:

What it does not do

It says what mix of work is coming and roughly when. It does not say how much work there will be, because volume turns on the economy, on policy and on how long people keep cars, none of which is on the record. And it cannot price the work: the public record carries no invoice values, so a workshop's own figures are the only place that answer lives.

It is a Great Britain mechanism. Northern Ireland tests at four years through the DVA and sits outside it. Hybrids cannot be read on it, and the report sets out why.

The national figures are the wrong instrument

Every reading above changes area by area. The arrival readings go down to each of the 361 local authority areas, and run across the local authorities of one English conurbation, the electric share of cars due a first MOT in 2028 spans about seven points between the highest and the lowest, on sites a short drive apart. A national average is the wrong instrument for planning one workshop.

Local readings are available to the businesses that serve the trade: workshop management software, parts and tyre distribution, training providers and trade bodies. They carry the same method and the same stated limits as the national report.

The report, and how to get it

Independent garage operators can ask for the report and we will send it. Businesses that serve the trade can ask about readings cut to the areas their customers are in. If any of this matches or contradicts what you see through the workshop door, that evidence is worth more than the model, and we would like to hear it.
