Is It Worth Repairing a Cracked Screen? (UK 2026 Decision Guide)

A cracked screen is the most common phone fault in the UK – and the most common reason people wrongly write off a perfectly good handset. The question isn't really "can it be fixed?" (almost always, yes). It's whether fixing it is the smart financial decision, or whether you'd be better off replacing the phone or trading it in.

This guide gives you a framework to decide in about two minutes, using real celltech repair prices and honest, approximate used-market values. No upsell – there are genuine cases where repair is the wrong call, and we'll be clear about those too.

Direct answer: Repairing a cracked screen is worth it when the repair costs less than roughly half the phone's current value and the rest of the device is in good working order. Most recent iPhones and flagship Androids fall comfortably inside that rule: an iPhone 13 screen at celltech starts from £74.95 against a typical used value of around £200–£290, so repair is an easy yes. It stops being worth it on very old phones, phones with multiple faults, or where the screen price approaches the handset's resale value – at which point trade-in or replacement usually wins.

The simple rule: the 50% test

Engineers and economists use the same shorthand for any repair-or-replace decision, and it works perfectly for phone screens:

The rule: Repair the screen if the repair costs less than about 50% of what the phone is currently worth, and the phone is otherwise healthy. If the repair costs more than half the device's value – or the phone has other failing parts – replacing or trading in is usually the better use of your money.

Two conditions, both of which matter:

• The 50% threshold – compare the quoted repair price to the phone's realistic current value (what it would sell for today, used), not what you paid for it.
• "Otherwise healthy" – the battery still holds a decent charge, it charges normally, the cameras and speakers work, and there's no liquid damage. A cheap screen fix on a phone that's about to fail elsewhere is throwing good money after bad.

Why 50%? Because below that line, repair almost always beats the alternative once you factor in the cost and hassle of buying another phone. Above it, the gap narrows until replacement makes more sense. It's a guide, not a law – a phone you love, or not wanting the upheaval of switching devices, can tip a borderline case toward repair.

What a cracked screen actually costs to fix

The single biggest reason people overestimate repair cost is that they imagine the manufacturer price. Independent repair is typically a fraction of it. Here are real celltech screen-repair prices (our standard published "from" rate) set against approximate used-market values, so you can apply the 50% rule at a glance.

Model	celltech screen repair (from)	Typical used value (approx)*	Worth repairing?
iPhone 11	£44.95	~£90–£150	Yes
iPhone 12	£59.95	~£130–£200	Yes
iPhone 13	£74.95	~£200–£290	Strong yes
iPhone 14	£99.95	~£290–£390	Strong yes
iPhone 15	£179.95	~£430–£540	Strong yes
Samsung Galaxy S24	£179.95	~£340–£470	Yes
Samsung Galaxy S23	£199.95	~£240–£330	Borderline
Samsung Galaxy S22	£199.95	~£170–£250	Borderline
Samsung Galaxy S21	£179.95	~£110–£180	Often not
Samsung Galaxy A54	£149.95	~£120–£190	Borderline

What drives the price

Two phones with cracked screens can sit hundreds of pounds apart, and it's rarely arbitrary:

• Panel technology. A basic LCD is far cheaper to source than a flexible OLED. Most flagships from the last few years use OLED, which is why a Galaxy S-series or Pro iPhone screen costs more than a budget handset.
• Model tier and age. Newer and Pro/Ultra models use larger, higher-resolution panels with more integrated components, so parts cost more. The newest models always sit at the top of the range until supply matures.
• Parts grade. We tier screens honestly. A standard-grade panel is the value option; a premium/OEM-grade panel matches the original for colour accuracy, brightness and touch feel, and costs more. For an iPhone 13, for example, our standard screen is from £74.95 and the premium panel is £149.95 – you choose.
• Bonded components. On some designs the glass, digitiser and display are fused, so a small crack still means replacing the whole assembly. That's physics, not markup.

Worked examples: applying the rule

The 50% test only makes sense in action. Here it is on three real-world situations.

Example 1 – iPhone 13 (clear repair)

Screen repair from £74.95; typical used value around £200–£290. The repair is roughly a quarter to a third of the phone's value – well under 50%. The iPhone 13 still receives software updates, batteries are inexpensive to refresh later, and resale demand is strong. Repair, comfortably. A new equivalent would cost many times more.

Example 2 – iPhone 15 (clear repair, even at a higher price)

Screen repair from £179.95 sounds like a lot until you weigh it against a used value of roughly £430–£540 – around a third of the device's worth. The higher absolute price doesn't change the verdict; the ratio is what matters. Repair.

Example 3 – older Galaxy S21 (think twice)

Screen repair is £179.95, but a five-year-old S21 in good condition is typically worth only around £110–£180 used. Here the repair meets or exceeds the phone's value, so the maths flips: unless the rest of the phone is genuinely excellent and you intend to keep it for a good while longer, you're likely better off trading it in toward a newer device. This isn't a Samsung problem – it's an age problem. Samsung OLED panels are dearer and flagships depreciate faster, so the line is simply reached sooner. The same logic retires any handset eventually.

When it's NOT worth repairing

Honesty builds trust, so here are the cases where we'll tell you to think hard before repairing – or steer you elsewhere:

• The phone is very old and low-value. If the screen price is close to or above the handset's used value, and you're not deeply attached to it, replacement or trade-in usually wins.
• There are multiple faults. A cracked screen and a swollen battery and a dodgy charging port stack up fast. At some point the combined repair bill outruns the device's value – though note that bundling repairs is still often cheaper than replacing, so it's worth getting a full quote first.
• There's underlying liquid or board damage. If the phone has been wet or won't power on reliably, a new screen alone won't fix it. Diagnose the real fault before spending on glass.
• You were already planning to upgrade. If you'd switch phones within weeks anyway, repair only to sell, where a working screen dramatically lifts the resale price (see the hidden costs below).

The hidden costs of NOT repairing

People delay screen repairs to save money, then quietly lose more than the repair would have cost. A cracked screen is rarely a stable, leave-it-alone condition:

• The crack spreads. Daily flexing and temperature changes turn a hairline into a spider's web. What starts as a cosmetic chip can become a dead touch zone or black patches – sometimes pushing a cheaper repair into a pricier one.
• Touch starts failing. Once the digitiser layer is compromised, you get ghost touches, dead spots and unresponsive areas. The phone becomes genuinely hard to use.
• Dust and moisture get in. A cracked screen breaks the phone's seal. Dust under the glass and moisture reaching the internals can cause faults far more expensive than the original crack – this is how a £75 job becomes a board-level one.
• Risk of injury. Shards of phone glass are sharp. Cracked screens cut fingers and faces, and glass fragments can lift off against your cheek or ear.
• Resale value collapses. A cracked screen slashes trade-in and resale values disproportionately – often by far more than the repair would cost. Fixing the screen before you sell or trade frequently pays for itself.

In other words, "living with it" usually isn't free. It defers a small, known cost in exchange for a larger, uncertain one.

Repair vs replace vs trade-in

For most people it's a three-way decision, not a yes/no. Here's how to choose:

• Repair when the screen costs under ~50% of the phone's value and the device is otherwise sound. This is the right answer for the clear majority of phones from the last four or five years. You keep your data, your settings and a device you already know – for a fraction of replacement cost.
• Replace when the phone has multiple faults, is past its useful life, or you've been wanting to upgrade anyway. Even then, repairing first to sell on can claw back more than the repair costs.
• Trade in when your phone still has decent residual value but repair economics are borderline. Crucially, trade-in calculators pay far more for a working screen than a cracked one – so a cheap repair beforehand can lift the offer by more than the repair price. Our trade-in vs repair guide shows how to run that comparison properly.

Repairing with celltech

If repair is the answer, where you have it done matters as much as the price. A few things set celltech apart:

• Transparent, published pricing. Every screen price is listed up front – no quote-walls, no "contact us for a price" that so many UK repairers hide behind. You can apply the 50% rule before you commit a penny.
• An honestly tiered parts choice. Standard-grade for value, premium/OEM-grade when you want an exact match for the original. We tell you the difference and let you decide.
• A 27-month standard guarantee. That's more than double the 12 months most independent UK repairers offer, and far longer than the manufacturer's typical 90 days on out-of-warranty repairs. If a screen develops a covered fault months later, you're protected.
• Free diagnostics on standard repairs – so if your "cracked screen" turns out to hide a deeper fault, you find out before you spend.
• UK-wide mail-in, tracked and insured both ways. You don't need to be near a shop – your phone is posted in, fixed by specialists and posted back, fully insured with tracking the whole way. We cover around 2,467 device models and are rated 4.8 stars.

Frequently Asked Questions

How do I know if my cracked screen is worth repairing?

Apply the 50% rule: if the repair costs less than about half what your phone is currently worth used, and the phone is otherwise healthy, repair it. For example, an iPhone 13 screen from £74.95 against a used value of roughly £200–£290 is a clear yes. If the repair approaches or exceeds the phone's value – common on very old handsets – consider trading in or replacing instead.

Is it cheaper to repair the screen or buy a new phone?

For almost any phone from the last few years, repair is dramatically cheaper. A screen repair is typically tens to a couple of hundred pounds; a comparable new phone is several hundred to over a thousand. Replacement only edges ahead when the phone is old, low-value, or has several faults at once.

Can I keep using a phone with a cracked screen?

You can, but it's a false economy. Cracks spread, touch response degrades, dust and moisture get inside (which can cause far costlier faults), and the glass can cut you. It also tanks the phone's resale and trade-in value – often by more than the repair would have cost. Fixing it sooner is usually the cheaper path overall.

Will a cracked screen affect my trade-in value?

Significantly. Trade-in and resale calculators downgrade a cracked-screen phone heavily – frequently by more than the price of repairing it. If you plan to trade in or sell, repairing the screen first often increases the offer by more than the repair costs, leaving you better off. See our trade-in vs repair guide.

Do you use genuine parts for screen repairs?

We offer an honestly tiered choice: a standard-grade panel as the value option, and a premium/OEM-grade panel that matches the original for brightness, colour accuracy and touch feel. We explain the difference and let you pick – rather than quietly fitting the cheapest part and charging for the best.

How long is the warranty on a screen repair?

Standard screen repairs carry a 27-month guarantee – more than double the 12 months most independent UK repairers offer, and far longer than the typical 90-day manufacturer warranty on out-of-warranty repairs. It reflects our confidence in the parts and the work.

Is it worth repairing the screen on an older phone?

Sometimes. Run the 50% rule and check the rest of the phone. If an older handset is still worth a reasonable amount, the battery and cameras are fine, and the screen price stays under half its value, repair makes sense. If the screen costs as much as the phone is worth, or there are other faults stacking up, trade-in or replacement is usually the smarter move. Our guide on when a phone is beyond economical repair covers this in detail.

How does mail-in screen repair work?

celltech is mail-in only and covers the whole UK. You book online, post your phone in, and it's repaired by specialists and posted straight back to you – tracked and fully insured in both directions. Standard repairs include free diagnostics, so if your cracked screen hides a deeper issue, you'll know before any work is agreed.
