Quick Reference: Average UK Repair Costs 2026

Before we dive into the detail, here's an at-a-glance table of the most common UK repair and replacement costs in 2026. Use this as your starting point, then read the relevant section below for a deeper breakdown.

The Repair vs Replace Decision Framework

Making a level-headed repair-or-replace decision when something breaks down isn't easy — especially when the breakdown is unexpected and you're under pressure. That's why we developed the Mend or End decision framework, a structured approach that removes the guesswork and helps you spend wisely. It's built on five key pillars.

The 50% Rule

This is the golden rule and the cornerstone of every recommendation on this site: if the repair cost exceeds 50% of the replacement cost, you should generally replace the item. It's simple, memorable, and backed by financial logic. For a deeper dive into why this works, read our full guide on the 50% rule explained.

For example, if a new washing machine costs £500 and the engineer's quote to fix yours is £280, that's 56% — above the threshold. Even if the repair extends the machine's life by a year or two, you're paying more than half the cost of a brand-new appliance with a full warranty and better energy efficiency. In that scenario, replacement is the smarter move.

The 50% rule works across virtually every category — from boilers and washing machines to smartphones and cars. Our free calculators apply it automatically alongside other factors to give you a personalised recommendation.

Age vs Expected Lifespan

Every product has an expected useful life. A boiler typically lasts 12–15 years, a washing machine 8–12 years, and a smartphone 3–5 years. If your item has already exceeded or is close to its expected lifespan, repairs become less economical because further breakdowns are statistically likely. Check our article on how long appliances last for a comprehensive lifespan chart.

A useful sub-rule: if an item has used more than 75% of its expected lifespan and the repair costs more than 30% of replacement, lean towards replacing. The maths shifts because the repaired item has limited useful years remaining.

Frequency of Recent Repairs

One breakdown is an event. Two breakdowns in a year is a pattern. If you've already repaired the same item within the last 12 months, the risk of further faults is significantly higher. Cumulative repair costs matter — add up everything you've spent on fixes over the past two years and compare that total against the replacement cost using the 50% rule.

Energy Efficiency Gains

Older appliances and heating systems consume substantially more energy than modern equivalents. A 15-year-old boiler might run at 70–80% efficiency while a new A-rated condensing boiler hits 92–94%. Over a year, the energy savings alone could be £200–£400 — effectively subsidising the cost of replacement. Our guide on energy ratings explained helps you quantify these savings, and our article on the true cost of running old appliances walks through the long-term numbers.

Environmental Considerations

Replacing isn't always the greener option. Manufacturing a new appliance has a significant carbon footprint — a new washing machine generates roughly 300–400 kg of CO₂ to produce and ship. Repairing extends the product's life and delays that environmental cost. However, if the energy savings from a new appliance are substantial, replacement can have a lower lifetime carbon impact. The best approach is to weigh both sides honestly rather than defaulting to either option.

Emotional vs Rational Decisions

It's human nature to cling to familiar items or, conversely, to use a breakdown as an excuse to upgrade. Neither impulse is inherently wrong, but it helps to separate the emotional response from the financial analysis. Our calculators are designed to give you the rational answer — then you can layer your personal preferences on top.

Heating & Plumbing Repair Costs Overview

Heating is the single biggest maintenance cost for UK homeowners. A boiler breakdown in January isn't just inconvenient — it's an emergency. According to Checkatrade, the average UK household spends around £350 per year on heating system maintenance and repairs. Here's what you need to know about the key costs in 2026.

Boilers

Boilers are the most expensive item to repair in most homes. Common faults include faulty diverter valves (£150–£300 to fix), fan failures (£200–£350), printed circuit board (PCB) replacements (£250–£450), and heat exchanger issues (£350–£500+). A brand-new combi boiler from Worcester Bosch, Vaillant, or Ideal costs £2,000–£4,500 fully installed, depending on the model and complexity of the installation.

If your boiler is under 8 years old and the repair is a single component, it's almost always worth fixing. Once it passes 12 years, apply the 50% rule rigorously. Modern condensing boilers are up to 25% more efficient than older models, which means you could save £200–£400 a year on gas bills by upgrading. For the full cost breakdown, visit our Heating & Plumbing Guide.

Radiators, Thermostats & Other Heating Components

Radiator repairs (bleeding, valve replacement, leak sealing) typically cost £80–£200. A new radiator installed runs to £200–£500 depending on size and type. Smart thermostat upgrades (Hive, Nest, Tado) cost £150–£250 including installation and can shave 10–15% off your heating bills. Immersion heater replacements average £150–£350, and heated towel rail repairs £80–£150.

Kitchen Appliance Repair Costs Overview

Kitchen appliances account for a huge chunk of household repair spending. The good news is that many kitchen appliance repairs are straightforward and relatively affordable — provided you catch the problem early. For a complete breakdown, see our Kitchen Appliances Guide.

Washing Machines

The most commonly repaired kitchen appliance in the UK. Typical faults include drum bearing failures (£130–£250), pump replacements (£80–£150), door seal changes (£60–£100), and control board issues (£120–£220). A new mid-range washing machine from Samsung, Bosch, or LG costs £350–£600, while premium models from Miele or AEG reach £800+. Most washing machines last 8–12 years. Our guide on how long appliances last covers this in detail.

Dishwashers, Ovens & Fridge-Freezers

Dishwasher repairs typically run £80–£200, with spray arm and pump faults being the most common. A new dishwasher costs £250–£700. Oven and cooker repairs average £80–£250 — element replacements, thermostat failures, and door hinge issues are the usual culprits. New ovens range from £300 for a basic model to £1,500+ for a range cooker. Fridge-freezer repairs cost £100–£300 (compressor and thermostat faults), with new units costing £300–£1,200.

Microwaves & Tumble Dryers

Microwaves are rarely worth repairing professionally — repair costs of £60–£120 are close to the price of a new unit (£50–£200). Tumble dryers are different: belt replacements (£60–£100), heating element swaps (£80–£150), and motor repairs (£120–£200) can all extend a dryer's life meaningfully when the machine is under 7 years old. Replacement costs £200–£700.

Tech & Electronics Repair Costs Overview

Tech repairs are some of the most debated. A cracked iPhone screen or a laptop that won't charge can feel like a catastrophe, but repair costs have actually come down in recent years — partly thanks to the right to repair movement and the growth of independent repair shops across the UK. For the full rundown, see our Tech Guide.

Smartphones

Screen repairs remain the most common smartphone fix. For iPhones, official Apple screen repair costs £150–£350 depending on the model, while third-party shops charge £80–£200. Android screen repairs from Samsung, Google, and OnePlus run £50–£250. Battery replacements cost £50–£90 and are almost always worthwhile — they can add 1–2 years to a phone's useful life. Given that a new flagship phone costs £800–£1,200, most single-component repairs comfortably pass the 50% test.

Laptops & Tablets

Laptop repairs range widely: keyboard replacements £60–£150, screen replacements £100–£300, SSD upgrades £50–£120, and motherboard repairs £200–£400. Tablets follow a similar pattern, with screen replacements at £80–£250. The key consideration with laptops is whether the internal components (processor, RAM) still meet your needs. A five-year-old laptop with a broken screen but decent specs is worth repairing; the same laptop with 4 GB of RAM and a slow processor probably isn't.

TVs & Gaming Consoles

TV repairs (backlight failures, power supply issues) cost £80–£250 but are only worthwhile on sets that cost £500+ originally and are under 5 years old. Cheap TVs under £300 are almost never worth repairing. Gaming consoles — PS5, Xbox Series X — have common faults like disc drive failures (£80–£150) and overheating issues (£60–£120). Given the £400–£500 replacement cost, most single-fault repairs make sense.

The Right to Repair

Since 2021, UK regulations have required manufacturers of certain appliances (including washing machines, dishwashers, and TVs) to make spare parts available for up to 10 years after a product is discontinued. This has made repairs more accessible and affordable. In 2025, the EU expanded the scope further, and the UK is expected to follow suit, potentially covering smartphones and laptops by 2027. This is good news for anyone who prefers to mend rather than end.

Garden Equipment Repair Costs Overview

Garden equipment repairs are often overlooked, but UK gardeners collectively spend millions each spring getting mowers, trimmers, and pressure washers back into working order. The good news: garden equipment is generally simpler in design, which means repairs tend to be cheaper and more straightforward. See our full Garden Guide for detailed breakdowns.

Lawn Mowers

The most commonly repaired garden item. Petrol mowers need blade sharpening (£15–£30), carburetor cleaning (£30–£60), pull-cord replacement (£20–£40), and occasional engine servicing (£50–£100). Electric and cordless mowers have fewer moving parts — motor replacements cost £60–£120 and battery replacements for cordless models £50–£120. A new petrol mower costs £150–£500 (Flymo, Bosch, Honda), while cordless models run £150–£600. Mowers last 8–15 years with proper maintenance.

Hedge Trimmers, Pressure Washers & Chainsaws

Hedge trimmer blade sharpening costs £15–£30, while motor or gearbox repairs run £40–£100. New trimmers cost £50–£250. Pressure washers commonly suffer from pump failures (£60–£150 to repair) and hose leaks (£20–£40); new units cost £100–£400 (Kärcher, Nilfisk, Bosch). Chainsaw chain sharpening is £10–£20, but bar or engine repairs can reach £80–£180, with new chainsaws costing £100–£450.

For most garden equipment, the 50% rule works well, but also factor in seasonal urgency — if your mower breaks down in June, you may not want to wait three weeks for parts.

Home Structure Repair Costs Overview

Structural home repairs are typically the most expensive items on this list, but they're also the ones where repair makes economic sense most often — because replacement costs are so high. A new roof costs £5,000–£15,000, so a £400 tile repair is almost always the right call. For comprehensive pricing, see our Home Structure Guide.

Windows & Doors

Window repairs — failed sealed units (misted double glazing), broken handles, faulty locks — cost £80–£250 per unit. A full window replacement costs £350–£1,000 per window depending on size, material (uPVC, timber, aluminium), and glazing spec. If the frame itself is sound and the issue is just misted glass, a sealed unit replacement at £80–£120 is excellent value. If frames are rotting, warped, or the windows are single-glazed, replacement is the way forward — and will significantly improve your home's EPC rating.

Door repairs (lock replacements, hinge adjustments, panel fixes) run £50–£200, while a new composite front door costs £800–£2,000 installed. Internal doors are cheaper: £100–£300 including fitting.

Roofs & Guttering

Roof repairs vary enormously: replacing a few slipped or broken tiles costs £150–£400, while fixing flashing or repointing ridge tiles runs £200–£600. Flat roof patches cost £200–£500. A full roof replacement on a typical 3-bed semi costs £5,000–£10,000 (pitched) or £2,000–£4,000 (flat). The roof is almost always a repair candidate unless it's structurally compromised or over 50 years old with widespread failures.

Guttering repairs (resealing joints, replacing sections) cost £50–£150, while a full gutter replacement costs £400–£900. Given the relatively low cost of gutter repairs and the damage that blocked or leaking gutters can cause to walls and foundations, this is one of the best-value maintenance jobs you can do.

Garage Doors

Garage door repairs — spring replacements, motor fixes on electric doors, panel replacements — cost £80–£300. A new garage door costs £600–£2,500 depending on type (up-and-over, roller, sectional) and material. If the door mechanism is sound and it's a cosmetic or minor mechanical issue, repair is nearly always worthwhile.

Vehicle Repair Costs Overview

Vehicle repair decisions carry some of the highest stakes — a car repair can run into thousands, and the wrong call can leave you with a money pit on wheels. The UK vehicle repair market is worth over £21 billion annually, covering everything from MOT-related fixes to major mechanical overhauls. For the full breakdown, see our Vehicles Guide.

Cars

The most common car repairs and their 2026 costs: brake pad and disc replacement £200–£400, clutch replacement £400–£800, timing belt/chain £300–£700, alternator replacement £250–£500, catalytic converter £400–£1,200, and gearbox repair £500–£1,500. Head gasket failures — the dreaded big one — cost £800–£2,000+ to fix.

The 50% rule for cars is nuanced. A car's value depreciates rapidly, so compare the repair cost against the car's current market value rather than the price of a brand-new vehicle. If the repair costs more than 50% of the car's current value, it's usually time to sell or scrap. Use our Car Repair vs Replace Calculator to input your car's details and get a data-driven answer.

MOT Failures

Around 37% of cars fail their first MOT presentation in the UK. The most common failure items — tyres, lights, brakes, suspension — are all repairable at reasonable cost. The average MOT repair bill is £150–£300. Except in cases of severe structural corrosion, it's almost always worth fixing an MOT failure on a car you plan to keep.

E-Bikes, Bicycles & E-Scooters

E-bike repairs are increasingly common as the market grows. Battery replacements cost £300–£800 (the single biggest expense), motor repairs £150–£400, and controller/display replacements £80–£200. A new e-bike costs £800–£3,000+, so battery and motor repairs typically pass the 50% test. Standard bicycle repairs — punctures (£10–£15), brake adjustments (£15–£30), gear servicing (£30–£60), wheel truing (£15–£30) — are almost always worthwhile. E-scooter repairs (battery £100–£300, motor £80–£200) are viable on premium models but rarely worthwhile on budget scooters under £300.

UK Tradesperson & Repair Costs 2026

Understanding how tradespeople charge is essential for budgeting any repair job. Most UK tradespeople charge either an hourly rate or a fixed price per job, plus a callout fee. For a deep dive into hiring tradespeople, read our guide on UK tradesperson costs in 2026.

The London Premium

If you live in London or the South East, expect to pay a 30–50% premium on most trade rates. This reflects higher living costs, congestion charges, and parking expenses for tradespeople working in the capital. Even within London, rates vary — central London commands the highest prices, while outer boroughs are closer to the national average.

Getting the Best Value

Always get at least three quotes for any repair over £100. Use platforms like Checkatrade, MyBuilder, or Bark to compare local tradespeople and read verified reviews. Ask whether the quote includes VAT, parts, and disposal of old materials. For gas and electrical work, always verify that your tradesperson holds the appropriate certifications — Gas Safe registered for gas engineers and NICEIC or NAPIT registered for electricians.

Trade Body Memberships to Look For

• Gas Safe Register — legally required for anyone working on gas appliances
• NICEIC / NAPIT — electrical competence schemes
• CIPHE — Chartered Institute of Plumbing and Heating Engineering
• Federation of Master Builders — general building work
• National Federation of Roofing Contractors (NFRC) — roofing work
• IMI / ATA — motor vehicle technicians

Membership of a recognised trade body doesn't guarantee quality, but it does mean the tradesperson has met minimum competence standards, carries insurance, and is subject to a complaints procedure. It's always worth checking.

Your Consumer Rights for Repairs in the UK

Understanding your legal rights can save you hundreds of pounds. The UK has robust consumer protection laws that apply to both products and repair services. For a full breakdown, see our guide on warranty and repair rights in the UK.

The Consumer Rights Act 2015

This is the cornerstone of UK consumer protection. Under this act, any product you buy must be of satisfactory quality, fit for purpose, and as described. If a product develops a fault within 30 days of purchase, you're entitled to a full refund. Between 30 days and 6 months, the retailer must offer a repair or replacement (and it's assumed the fault was present at purchase). After 6 months, the burden shifts to you to prove the fault was inherent — but you still have rights for up to 6 years from purchase (5 years in Scotland).

Manufacturer Warranties

Most appliances come with a 1–2 year manufacturer warranty. Some premium brands offer longer: Miele provides a 2-year warranty extendable to 5 years, and Worcester Bosch offers up to 12 years on certain boiler models. Always register your product's warranty — many manufacturers require registration within 30 days of purchase to activate the full warranty period.

Extended Warranties — Worth It?

In most cases, no. Which? research consistently shows that only around 10% of appliances develop a fault in the first 3–5 years. The cost of a typical extended warranty (£50–£150 per year) often exceeds the expected repair cost over the same period. A better strategy: set aside £20–£30 per month into a home repairs fund. Over a few years, you'll build a buffer that covers most unexpected repairs without paying a premium to an insurer.

The exception: very high-value items like boilers (where a service plan at £10–£15/month includes the annual service) or range cookers may justify cover for peace of mind.

Section 75 Credit Card Protection

If you paid for an item costing between £100 and £30,000 using a credit card, Section 75 of the Consumer Credit Act 1974 makes your card provider jointly liable with the retailer. This means you can claim against your credit card company if the product is faulty, even if the retailer has gone bust. It's one of the most powerful consumer protections in the UK — and it costs you nothing.

What to Do if a Repair Goes Wrong

1. Contact the tradesperson or repair company in writing (email is fine) to explain the problem.
2. Give them a reasonable opportunity to put it right — typically 14 days.
3. If they refuse or the re-repair fails, you can reject the service and claim a partial or full refund.
4. Use your credit card provider's chargeback or Section 75 process if applicable.
5. As a last resort, file a claim through the small claims court (up to £10,000 in England and Wales, £5,000 in Scotland). The process is straightforward and doesn't require a solicitor.

Right to Repair Legislation

UK right to repair regulations (introduced July 2021) require manufacturers of certain products — washing machines, dishwashers, fridges, TVs, and lighting — to make spare parts available for up to 10 years after a model is discontinued. Parts must be deliverable within a reasonable time and with standard tools. This legislation is expected to expand to cover more product categories, including smartphones and laptops, in the coming years — a significant win for consumers who want to mend rather than end.

How to Use Our Free Calculators

At Mend or End, we've built a suite of free repair vs replace calculators designed specifically for UK homeowners. Each calculator takes under 60 seconds to complete and gives you a clear, data-backed recommendation. Here's how they work.

What Data We Use

Our calculators draw on cost data from Checkatrade, Which?, MyBuilder, manufacturer pricing, and contributions from our user community. We update the data regularly to reflect current 2026 prices. Each calculator considers:

• Your item's age — compared against average lifespan data
• Current condition — general wear, number of previous repairs
• The specific fault — some faults are cheap to fix, others signal deeper issues
• Your repair quote — compared against the 50% rule threshold
• Energy efficiency — potential savings from upgrading to a modern equivalent
• Brand and model — some brands have better parts availability and reliability records

How the Recommendation Works

The calculator produces a percentage confidence score — for example, "78% Replace" or "85% Repair". This isn't a binary yes/no; it's a nuanced assessment that weighs all the factors above. A score near 50/50 means it's genuinely a toss-up — in which case we'll explain the trade-offs and let you decide. Scores above 70% in either direction are strong recommendations backed by the data.

Available Calculators

We currently offer calculators for the most commonly repaired items in UK homes:

• Boiler Calculator — the most-used calculator on our site, covering all combi, system, and conventional boilers
• Washing Machine Calculator — covers all brands and fault types
• Smartphone Calculator — iPhone, Samsung, Google Pixel, and more
• Car Calculator — factors in mileage, MOT history, and current market value
• Window Calculator — individual window units, including misted double glazing
• Lawn Mower Calculator — petrol, electric, and cordless models

Each calculator is completely free, requires no sign-up, and gives you a result you can act on immediately. We encourage you to try multiple calculators if you have several items that need attention — many households find it useful to prioritise their repair and replacement budget across all their ageing appliances and equipment.
