Evidence basis: UK planning method; government rates checked 26 August 2026; all shop scenarios and downloadable rows are fictional calculations, not industry averages or forecasts.

A phone repair shop can produce anything from side-income to a multi-site turnover, so one “average revenue” figure is misleading. Public UK data does not isolate the revenue and profit of phone-repair shops well enough to support a universal claim. The honest answer comes from four local inputs: completed jobs, average selling price, direct cost per job and monthly fixed costs.

This guide shows the calculation and three worked scenarios. They are planning examples, not industry averages.

Quick formula: monthly operating profit before tax, finance and owner drawings = completed-job revenue + other gross profit − direct repair costs − fixed operating costs.

How Much Do Phone Repair Shops Make on Average?

There is no reliable current UK average for phone-repair-shop revenue. The sector sits inside broader statistical categories, while shops mix repairs with accessories, refurbished devices, trade-ins and business contracts. A turnover average would also conceal rent, staffing and parts differences.

Use a shop-level model instead:

  1. Count only completed, collected and paid jobs.
  2. Separate VAT where applicable.
  3. Subtract parts, consumables, direct labour, payment fees and a warranty provision.
  4. Add gross profit from accessories or device sales, not their full sales value.
  5. Subtract rent, payroll overhead, utilities, insurance, software, marketing and other fixed costs.

The result is operating profit before tax, debt service and owner drawings. It is not the cash balance and it is not the owner's salary.

This page owns the revenue-to-owner-pay calculation. The separate phone-repair business viability test asks whether a particular local offer should exist; it should not supply an “average margin” to this model.

What Numbers Should a Shop Track?

MetricCalculationWhy it matters
Completed jobsPaid repair tickets in the periodQuotes and open tickets do not pay bills
Average selling priceRepair revenue ÷ completed jobsShows ticket value, but not margin
Contribution per jobPrice − variable costFunds overhead and profit
Contribution rateContribution ÷ priceUseful when the repair mix changes
Break-even jobsFixed costs ÷ contribution per jobTurns overhead into a daily target
Warranty/rework rateRepeat jobs ÷ completed jobsExposes quality and supplier problems
Labour utilisationProductive bench hours ÷ paid hoursShows capacity without rewarding rushed work
Quote-to-book rateBooked jobs ÷ valid quotesMeasures the customer journey

Review these by repair type and device model. A blended margin can hide an uneconomic service.

What Are the Profit Margins on Phone Repairs?

There is no defensible universal percentage. Consider two repairs both sold at £100:

Selling price£100£100
Part and consumables£28£52
Direct labour£18£18
Fees and warranty provision£6£7
Contribution£48£23

Turnover treats them as equal; contribution does not. Repair B may still be worthwhile if it fills spare capacity, leads to valuable work or serves an important customer, but that should be an explicit decision.

Do not confuse markup and margin. Buying a part for £40 and charging £80 is a 100% markup on the part, but the gross margin on that £80 is 50% before labour, fees and warranty costs.

Use the repair pricing method to build the job-level contribution input rather than copying a percentage from another shop.

What Does a Phone Repair Shop Cost to Run Each Month?

Build fixed costs from actual quotes:

  • rent, service charge and business rates where due;
  • salaries, holiday, pension and employer National Insurance;
  • electricity, broadband, phone and security;
  • insurance and professional fees;
  • software and payment-terminal subscriptions;
  • marketing and local sponsorship;
  • cleaning, waste, packaging and small tools;
  • finance repayments and equipment leases;
  • an owner's market-rate working wage for planning purposes.

From April 2026, the UK National Living Wage for workers aged 21 and over is £12.71 an hour. Employer costs can also include pension, holiday and National Insurance; the main employer NI rate is currently 15% above the applicable threshold. Use the live minimum-wage rates and 2026–27 employer thresholds, not an old salary estimate.

VAT can materially alter the model. The current compulsory registration threshold is more than £90,000 of taxable turnover, subject to the detailed rules. Check HMRC's registration guidance and take advice rather than treating VAT collected as revenue.

Three Worked Scenarios

These examples use invented but internally consistent inputs so you can copy the method.

Download the phone-repair-shop profit model. It includes paired base and downside rows for each scenario plus a blank live row. Replace every input with current shop evidence; the file does not calculate VAT, tax, debt service, owner drawings or cash movement.

Scenario 1: booked solo bench

4.5 completed jobs/day × 22 days | 99 jobs

Average selling price | £90

Repair revenue | £8,910

Average contribution/job | £39

Repair contribution | £3,861

Accessory/device gross profit | £500

Total contribution | £4,361

Fixed operating costs | £2,300

Operating profit before tax/finance/drawings | £2,061

This can provide an owner income, but illness, holidays and warranty work directly affect capacity.

Scenario 2: small high-street shop

8 completed jobs/day × 26 days | 208 jobs

Average selling price | £100

Repair revenue | £20,800

Average contribution/job | £42

Repair contribution | £8,736

Accessory/device gross profit | £1,700

Total contribution | £10,436

Fixed operating costs | £8,200

Operating profit before tax/finance/drawings | £2,236

This example produces much more turnover but only slightly more operating profit because premises and staffing consume contribution.

Scenario 3: established mixed-revenue operation

15 completed jobs/day × 26 days | 390 jobs

Average selling price | £105

Repair revenue | £40,950

Average contribution/job | £46

Repair contribution | £17,940

Other gross profit | £5,200

Total contribution | £23,140

Fixed operating costs | £16,500

Operating profit before tax/finance/drawings | £6,640

The operation is attractive only if the volume, quality and other gross profit are repeatable. A 10% fall in repair volume would reduce contribution by £1,794 before any fixed cost changes.

The downside rows in the download change several inputs together. This is deliberate: a slower month can combine fewer jobs, a lower collected price, a weaker mix and the same fixed overhead. Do not approve premises, hiring or stock from a base case alone.

How Many Repairs a Day Does a Shop Need?

Use the contribution break-even formula.

If fixed costs are £8,200 and average contribution is £42:

Across 26 trading days, that is 7.5 completed jobs a day. Round up, then add the owner's target profit:

For a £4,000 target in the same shop:

This is more useful than asking whether another shop turns over £25,000.

What Determines the Result?

Repair mix

Track demand and contribution, not just job count. A day of quick low-contribution work differs from a day of carefully diagnosed high-value jobs. The phone-repair business viability test shows how to validate the local demand behind the model.

Parts and warranty performance

Record failure and return rates by supplier, part line, model and technician. The cheapest invoice price may have the highest landed cost after repeat labour.

Connect repeat work to the repair-shop warranty controls rather than hiding it in fresh revenue.

Staffing and throughput

More staff should expand tested, collected work or improve service. Measure paid hours, productive bench time, rework and queue length together so utilisation does not reward rushed repairs. Before adding paid capacity, use the competence stages in how long it takes to learn phone repair.

Customer response

Missed calls and slow quotes lose work before it reaches the bench. A current pricebook, clear booking path and prompt updates can raise completed volume without changing local demand.

Stock and cash

Refurbished phones and parts can make good gross profit while creating a cash shortage. Monitor stock age, deposits, supplier terms and days from completion to collection. Model owned devices separately using the refurbished phone business guide, and put the funding requirement into the start-up cost worksheet.

The inventory-control guide owns stock states and counts. The cash-flow guide owns the timing difference between a profitable month and an empty bank account.

How Can a Shop Increase Profit Safely?

  1. Reprice or stop repairs that fail the contribution test.
  2. Reduce repeat labour through better testing and supplier feedback.
  3. Collect deposits for special-order parts under clear terms.
  4. Improve quote response and booking rather than buying more traffic first.
  5. Add related services only after modelling their own costs and obligations.
  6. Schedule work to technician competence and parts availability.
  7. Review the pricebook whenever part or wage costs change.

cellbot provides an AI front desk and CRM for repair shops, resellers and refurbishers. It can quote from the shop's pricebook, handle bookings and payments and keep customer messages in one workflow. Those tools can reduce delay and inconsistency; they do not create margin if prices and costs are wrong.

Measure the result with stable definitions from the repair-shop KPI guide, then reconcile completed work to the repair-shop accounting method. Software activity is not accounting evidence by itself.

Revenue, Profit and Owner Pay Are Different

  • Revenue is sales before costs and VAT treatment.
  • Gross profit or contribution is what remains after relevant direct costs.
  • Operating profit is what remains after overhead.
  • Cash flow also reflects stock purchases, loan movements, tax timing and unpaid sales.
  • Owner pay may be salary, drawings or dividends depending on the structure and is not automatically equal to profit.

Ask an accountant to set up the treatment correctly. For planning, include a market-rate owner wage in the cost base even if cash is not drawn immediately; otherwise the business can look profitable only because the owner works for free.

Frequently Asked Questions

Can a phone repair shop make six figures?

It can exceed £100,000 in annual turnover at modest daily volume. That does not mean the owner earns six figures. Apply the contribution and overhead model to determine owner income.

What is the most profitable repair?

There is no permanent winner. Compare realised contribution per bench hour, demand, repeat rate and required stock for each model and repair.

Does location matter?

Yes. It changes rent, visibility, competition, opening hours, customer mix and delivery options. Test booked demand before taking a long lease.

How long until a shop becomes profitable?

It depends on the starting fixed cost, contribution and speed of demand growth. Model month-by-month cash, not a single steady-state year.

Bottom Line

Do not ask only what phone repair shops make. Ask how many completed jobs your shop can win, what each contributes and how much overhead that contribution must carry. A one-page model using real prices, parts, labour and rent will be more reliable than any uncited industry average.
