BRIEF 1 — The Repair Ratio

The idea. Repair-versus-replace is not a judgement. It is a comparison of two costs per year of service delivered, and it has a closed form.

                (w·h + p + k) · L_n
        R  =  -------------------------        repair when  R < 1
                   q · L_r · C_n

w is the charge-out labour rate, h the hours including diagnosis, p the part, k the fixed cost of the job — callout, carriage, bench time — and q the probability the repair holds first time. L_r is the residual life the repair buys, L_n the life of a new unit, C_n its price.

q is in the denominator because failed attempts are paid for too. A trade that fixes eight jobs in ten is charging the two failures to the eight.

Worked example. A UK washing machine: new at £400.00, life 11 years, repair buys 5, pump £45.00, callout £60.00, 1.20 hours, fixed first time 90 percent of the time. At £45.00 an hour the ratio is 0.9717 and repair wins. At £70.00 an hour it is 1.1550 and replacement wins.

The figure to carry. Nothing about the machine changed between those two lines. Only the wage did.

You already know this because you have already made this calculation about a car, silently and without writing it down, and what you were actually weighing was how many more years it had in it against what the garage would charge.

BRIEF 2 — The Threshold Labour Rate

The idea. Rearrange the ratio for the only variable that moves and you get the number to put on a page.

          q · L_r · C_n / L_n  −  p  −  k
   w*  =  --------------------------------
                        h

w* is the hourly rate below which repair is cheaper per year of service. It is a property of the product, not of the repairer — and once computed it settles the argument for the whole category.

Worked example, three products.

The figure to carry. At a $132.00 bench rate the phone repair runs at R = 0.4932 — under half the cost of replacement per year served. That is why phone repair is a large unsubsidised industry and kettle repair is not, and neither fact has anything to do with how anybody feels about waste.

You already know this because you have taken a phone to be fixed and would not dream of taking a kettle, and nobody had to explain the difference.

---

BRIEF 3 — Residual Life Is the Strongest Lever

The idea. Of the four terms you can move, L_r — how many more years the repair buys — moves the threshold further than any other, and it is the one almost nobody legislates.

Worked example. The same washing machine, each lever pulled alone:

The figure to carry. Halving the price of the part — the demand every repair campaign leads with — buys £18.75 an hour. Adding three years of residual life buys £81.82, more than four times as much.

Why it matters. It reframes durability. A machine built to survive its own repair is not a gift to the customer at the manufacturer's expense: it is a labour subsidy, and it is the largest one available in the equation. The EU directive's twelve-month guarantee extension for choosing repair is the only major provision anywhere that acts on this term, and it acts on it from the consumer's side.

You already know this because you have paid more for the boots that could be resoled, and the reason was never the sole. It was the four years.

BRIEF 4 — k, and Why Repair Is Urban

The idea. k is the cost of getting the broken object and the skilled person into the same room. It does not scale with the job's difficulty, it scales with distance, and it is why repair economics are geographic.

Worked example. Removing the £60.00 callout from the washing machine job — by having the customer bring it to a counter, or by routing through a collection point — moves the threshold from £48.86 to £98.86 an hour. That single change more than doubles the rate at which repair still wins. It requires no new technology, no legislation and no manufacturer's cooperation.

The figure to carry. France's repair fund is underspent: €29.3 million paid against €130.0 million budgeted for its first three years, 22.5 percent uptake. The subsidy was correctly sized and poorly reached, and reach is k.

Why it matters. Density is the repair business's real asset. Mail-in works for a phone because carriage is small against C_n; it fails for a washing machine because carriage is enormous against it. The categories sort themselves, and a network that ignores the sorting loses money quietly for years.

You already know this because you have not repaired something you owned simply because of where the shop was.

BRIEF 5 — First-Time Fix, q

The idea. A repair that does not hold is paid for twice. q sits in the denominator, so a shop that fixes seven in ten is carrying a 43 percent loading on every successful job relative to one that fixes ten in ten.

Worked example. Volunteer community repair is measured, publicly, and the number is honest: across 208,491 logged attempts by 1,158 groups at 19,986 events in 31 countries, the fix rate is 53.0 percent — 110,500 objects saved. That is a genuinely good result for volunteers working without parts inventories, and it is also a clear statement of why the professional trade charges what it does. Professionals buy q with diagnostic data, tooling and a parts position.

The figure to carry. 10.43 attempts per event. Community repair is not small because people do not care. It is small because k is high and the sessions are monthly.

Why it matters. q is the term you can raise fastest inside a firm, because it is bought with recorded experience rather than with capital. And time-to-fault falls as q rises, so raising q lowers h as well: it is the only lever that moves two terms at once.

You already know this because you have watched one person find a fault in minutes that another had been hunting for an afternoon, and you knew exactly which of them you wanted next time.

BRIEF 6 — Charge-Out Is Not Wage

The idea. The w in the equation is a charge-out rate. It carries premises, insurance, the van, the parts float, the diagnostic subscriptions and every unbilled hour. It is a multiple of what the technician is paid, and the multiple is large.

Worked example. The United States publishes both sides. The average shop labour rate is $132.00 an hour; the median wage of an automotive service technician is $24.34. The multiple is 5.4232.

Apply it to the washing machine. w* = £48.86 implies a technician wage of £9.01 an hour — 70.9 percent of the UK National Living Wage of £12.71 from April 2026. The minimum viable charge-out rate at that wage is £68.93; the shop is short £20.06 an hour, or £24.08 on the job.

The figure to carry. £9.01. Repairing a four-hundred-pound washing machine, done properly and legally, does not pay the legal minimum in the United Kingdom.

Why it matters. This is the chapter's honest negative and it is distributional. Repair is labour-intensive, so it is structurally strongest where labour is cheapest — and the countries legislating hardest for it are the countries where the arithmetic is tightest. Any account of repair that does not say this out loud is selling something.

You already know this because the last quote you had for a domestic repair made you look up the price of a new one, and you were not being unreasonable.

BRIEF 7 — Parts Pairing Is an Hour Cost

The idea. Parts pairing is the practice of using serialised software so a device refuses, degrades or complains when it meets a component the manufacturer did not personally supply. It looks like a parts problem. It is not. It is an h problem, and h is in the denominator of the threshold.

Worked example. A twenty-minute component swap that ends in an unresolvable software refusal does not become a slightly more expensive job. It becomes a job that cannot be completed, which means it consumed diagnostic time, produced no revenue, and lowered q for the shop that attempted it.

On the washing machine, halving h from 1.20 to 0.60 hours lifts the threshold from £48.86 to £97.73 an hour. Doubling it does the reverse with equal force.

The figure to carry. Oregon banned parts pairing for devices manufactured after 1 January 2025 — the first jurisdiction anywhere to do so. On the arithmetic, that is the most economically consequential right-to-repair provision written to date.

Why it matters. Campaigns ask for parts and documentation, which act on p, the weakest lever. The software behaviour acts on h, the second-strongest. The measure that photographs worst does the most work.

You already know this because the difference between a job you can do and a job you cannot has never been the price of the part.

BRIEF 8 — Information Versus Price

The idea. Two French instruments, two measured outcomes. One informs, one pays. Only one of them moved.

The index. The indice de réparabilité — 0 to 10, five criteria, five categories, mandatory from 1 January 2021, replaced for televisions and washing machines by a durability index on 7 January 2025. The government evaluated it against more than 20,000,000 sales lines over three years from two retailers. Effect on sales of more repairable goods: positive and statistically significant online; positive and not statistically significant in store. Awareness 55.0 percent; 66.0 percent called it useful.

The bonus. A direct subsidy at the till: €25.00 for a washing machine at launch, €50.00 from 2024. Repairs funded went from 181,000 in 2023 to 715,227 in 2024 — a factor of 3.952 — with payouts rising from €4,000,000 to €24,300,000, an average of €22.10 a repair rising to €33.98.

The figure to carry. The arithmetic says the subsidy that closes the gap on the washing machine is £24.08. France launched at twenty-five euros. Not the same currency and not the same machine, so read it as an agreement of magnitude rather than an identity — but the magnitude is the finding.

Why it matters. Information is not one of the four levers. Price is two of them at once, p and k. An index tells a buyer which machine to buy; it does nothing for the machine already in the kitchen.

You already know this because a label has never once changed what you did with something already broken.

BRIEF 9 — Annex II Is a List, Not a Right

The idea. The scope of a repair law is the law. Everything else is detail.

The instrument. Directive (EU) 2024/1799, adopted 13 June 2024, published 10 July 2024, in force 30 July 2024, applying from 31 July 2026. Manufacturers must repair at a reasonable price and within a reasonable time, inside and outside the guarantee; must supply parts and tools to any repairer, professional or not; and the consumer who chooses repair over replacement gets 12 months of additional legal guarantee. A European repair platform follows: common interface by 31 July 2027, fully operational by 1 January 2028. Light-means-of-transport batteries enter scope on 18 February 2027.

The catch, stated plainly. The repair obligation reaches only the goods in Annex II, and Annex II reaches only goods that already carry ecodesign repairability requirements. Vacuum cleaners are named and no such requirements exist for them, so the naming does nothing at all.

The figure to carry. 31 July 2026 is the date the obligation begins, and it is also the date after which a manufacturer is a legally compellable parts supplier — which is the single most valuable fact in this chapter for anyone building a repair line, because it turns a commercial negotiation into a statutory one.

You already know this because you have read a policy that sounded universal and then found the schedule at the back.

BRIEF 10 — Where the Margin Actually Sits

The idea. In the repair economy, value accrues to whoever is not doing the repairing, unless somebody deliberately arranges otherwise.

Worked example, two firms selling the same object.

Back Market's revenue grew 19.28 percent on GMV of $2,800.0 million the prior year; its Spanish business runs €450.0 million of GMV on €55.0 million of revenue, a 12.22 percent take rate, at a 20.0 percent EBITDA margin. Swappie improved from −10.6 percent on a €22.00 million loss to −8.5 percent on €21.00 million.

The figure to carry. 43.47 points of margin separate the French marketplace from the refurbisher, and all of it is the labour term.

Why it matters. This is not an argument against marketplaces, which do real work and carry real risk. It is the instrument confirmed in published accounts: w·h is the whole difficulty, and a repair business that does not have a plan for it — a parts margin, a density strategy, a fault library, a residual-life warranty it can price — is selling labour at cost.

You already know this because you have noticed which businesses in your own sector own the relationship and which ones own the van.
