Water-Damaged Phone: Repair, Claim, or Write It Off? (UK 2026)

A phone in water is one of the few faults where the first ten minutes matter more than the next ten days. Tea, a toilet, a pool, a washing machine cycle – however it happened, what you do next has a real effect on whether the phone (and the photos on it) can be saved. And then there's the harder question: once the panic passes, is it worth repairing, worth claiming on insurance, or genuinely beyond saving?

This guide answers both: honest first aid (the few things that actually help, and the popular "fix" that does nothing), then the decision – repair, claim, or write it off – with real celltech prices so you can do the maths rather than guess.

Direct answer: Power the phone off, do not charge it, do not put it in rice, and get it to a professional for an ultrasonic clean as soon as possible – corrosion, not the water itself, is what kills phones. At celltech, water-damage treatment (full strip-down, ultrasonic clean and diagnosis) starts from £44.95 on most older iPhones and runs to £119.95–£149.95 on the latest sealed models; severe cases needing board-level work are quoted after diagnosis. Cost is driven by how long the liquid sat, whether corrosion reached the logic board, and how tightly the model is sealed. Liquid and board-level repairs carry our 120-day guarantee.

Part 1: First aid – the first 10 minutes

Liquid damage is rarely about the water. It's about corrosion – the slow electrochemical reaction that begins the moment moisture, power, and metal meet. That's why a phone can survive a dunk and seem fine, then die two days later. Your job in the first few minutes is to stop that reaction taking hold. Here is what genuinely helps, in order.

• Power it off immediately. If it's on, switch it off. Powered circuits plus moisture is exactly the combination that corrodes and short-circuits components. Do not check if it "still works" – every minute it's on is doing damage.
• Do not charge it. Putting a charger into a wet port is one of the most reliable ways to turn a recoverable phone into a dead one. Pushing current through a wet board can short the power circuit permanently. Leave it off and unplugged.
• Dry the outside and get the water out. Wipe it down with a soft cloth, and gently tip out any water sitting in the charging port and speaker grilles. Don't shake it hard or you'll spread liquid deeper inside.
• Don't use heat. No hairdryers, radiators or airing cupboards. Heat can warp seals and push moisture further into the device.
• Get it to a professional fast. The single most useful thing you can do is have it opened, cleaned and dried properly before corrosion sets in. A same-week ultrasonic clean is worth far more than days of any home "drying" method.

Why the rice trick is a myth

Burying a wet phone in a bowl of rice is the most repeated advice on the internet, and it doesn't work. Rice is a mediocre desiccant – it pulls a little moisture from the air, slowly, from the outside of a sealed device. It does nothing for the water already sitting on the logic board inside, which is the part that matters. Worse, while the phone sits in a bowl for two days "drying out", corrosion is quietly spreading across the board – and rice tends to leave starch and grains in the charging port too. If you take one thing from this guide: skip the rice, and book a clean.

What water actually does to a phone

Modern iPhones carry IP ratings (IP67 or IP68 on recent models), so they resist splashes and brief immersion in fresh water – when the seals are perfect and new. Two things undo that. Seals age: the adhesive and gaskets degrade with every drop, temperature change and previous repair, so a three-year-old phone is nowhere near its original rating. And IP ratings are tested in clean water – salt water, pool chlorine, tea, coffee and fizzy drinks are far more corrosive than the lab conditions allow for.

Once liquid is inside, it bridges contacts that were never meant to touch and corrodes solder joints and tiny components. This is why water damage is genuinely unpredictable: an identical-looking spill can mean a phone that needs nothing more than a clean, or one that needs a charging IC replaced. Nobody – not us, not Apple – can give a firm price before the device is opened and inspected, which is exactly what makes the "repair, claim, or write off" question harder for water than for a cracked screen.

Water-damage repair costs at celltech

celltech publishes its water-damage treatment prices rather than hiding behind a quote-wall. The figures below are the starting cost for the core service: a full strip-down, ultrasonic clean of the board, drying and diagnosis. If the clean alone revives the phone, that's all you pay. If corrosion has damaged specific components, any board-level work is quoted after diagnosis – we never invent a flat price for severe damage before we've seen the board.

If your exact model isn't listed, contact us for a quote – we cover roughly 2,467 device models. Remember these are treatment-and-diagnosis prices, not a guaranteed total: a phone that was off when it got wet and reached us quickly often needs nothing beyond the clean; one charged in a wet port and left for a week is a different conversation.

What drives the cost

• How long the liquid sat, and whether it was powered. The single biggest variable. A quick clean on a phone that was switched off is the cheap, good-outcome scenario. Days of corrosion on a powered board is where board-level work and higher costs come in.
• Whether corrosion reached the logic board. If damage stops at connectors and flex cables, it's straightforward. If a power-management or charging IC has corroded, that's component-level (microsoldering) work, quoted after diagnosis.
• How tightly the model is sealed. Newer iPhones (14, 15, 16 Pro, 17 family) are far harder to open, re-seal and waterproof again, which is why their treatment prices are higher than a 2019 handset.
• The type of liquid. Salt water and sugary or acidic drinks corrode faster and dirtier than clean tap water, meaning more cleaning and a higher chance of component damage.

Part 2: Repair, claim, or write it off?

Once the phone is stabilised, you have three realistic routes. The right one depends on the repair quote (which you'll only have after diagnosis), the value of the phone, your insurance situation, and – crucially – whether there's data on it you can't afford to lose.

Option 1: Repair it

For the majority of water-damage cases, a professional ultrasonic clean is the sensible first move – it's relatively inexpensive, it's often all that's needed, and it's the only route that reliably recovers your data. Because so many spills resolve at the clean stage, paying for diagnosis first and deciding afterwards is usually the lowest-risk path. You find out what's actually wrong before committing to anything bigger.

Option 2: Claim on insurance

If your phone is covered by accidental damage insurance – a standalone policy, a packaged bank account, or a contents-policy add-on – liquid damage is usually included where simple wear is not. The catch is the excess. Many policies carry an excess of £75–£150 or more, and a claim can affect your premium or no-claims position. If a clean revives your phone for the treatment price above, that's often cheaper than your excess – and you keep the claim in reserve for something more serious. Claims tend to make sense when diagnosis reveals heavy board damage on a high-value handset and the repair quote approaches the excess. We compare the numbers in our guide on repair vs insurance claim: which is cheaper.

Option 3: Write it off

Sometimes the honest answer is that a phone isn't worth saving – severe board damage on an older, low-value handset, where the quoted repair gets close to the cost of a good refurbished replacement. But "write it off" should almost never mean "bin it without a thought", for one reason: the data. More on that below. For the wider economics of when to stop spending, see our guide on when a phone is beyond economical repair.

Data recovery: the reason to try anyway

Here's the part people forget in the panic. Even a phone that won't turn on isn't necessarily a phone whose data is gone. The photos, messages and contacts you actually care about live in storage on the logic board, and a board that's too corroded for a long, reliable life can sometimes be cleaned and revived just long enough to back everything up.

That changes the maths. Even if you've already decided to replace the handset, a clean and recovery attempt can be worth it purely to rescue irreplaceable data before the phone is retired – far cheaper than specialist data-recovery labs, and worth asking about before you write anything off. See our guide on data recovery from a dead phone for what's realistic.

Is it worth repairing? A quick decision steer

• Get it cleaned first if the phone has any value to you, or holds data you haven't backed up. Diagnosis is cheap relative to the alternatives and often the only step needed.
• Lean towards an insurance claim if diagnosis reveals serious board damage on a recent, high-value iPhone and the repair quote is at or above your policy excess.
• Consider writing it off if the phone is old and low-value and the board is badly corroded and your data is already safely backed up – but ask about a recovery attempt first if it isn't.
• Whatever you do, don't keep using it "while it still works" – intermittent post-water faults usually get worse as corrosion spreads.

How celltech handles water damage

celltech is a UK-wide mail-in repair specialist. You book online, post the phone to us tracked and insured both ways, and we get to work – for water damage, that means a prompt strip-down and ultrasonic clean rather than leaving corrosion to spread. Pricing is published up front (the table above), we're 4.8-star rated, and liquid and board-level repairs carry a 120-day guarantee. That's deliberately shorter than the 27-month guarantee on standard parts like screens and batteries – liquid damage is inherently less predictable, and we'd rather be honest than over-promise – but it's still longer than the 90 days you'd typically get from a manufacturer repair.

Frequently asked questions

How much does water-damage repair cost?

At celltech, water-damage treatment (strip-down, ultrasonic clean and diagnosis) starts from £44.95 on most older iPhones, rising to £119.95–£149.95 on the latest sealed models. That covers the core service; if corrosion has damaged specific components, any board-level work is quoted after diagnosis rather than charged at a guessed flat rate.

My phone still works after getting wet – do I need to do anything?

Yes. A phone that survives a spill can fail days later as corrosion takes hold. Back up your data straight away, and have the phone cleaned properly. "It still works" is the best possible time to act, not a reason to ignore it.

Can you recover photos from a phone that won't turn on?

Often, yes. Your data lives in storage on the logic board, and a corroded board can sometimes be cleaned and revived long enough to back everything up – even when the phone isn't viable for long-term use. It's always worth asking about a recovery attempt before writing a phone off.

Should I claim on insurance or just pay for the repair?

Compare the repair quote with your policy excess. If a clean revives the phone for less than your excess, paying directly is usually cheaper and keeps your no-claims intact. If diagnosis reveals heavy board damage on a valuable phone and the quote approaches or exceeds the excess, a claim may be the better option.

Aren't modern iPhones waterproof?

They're water-resistant, not waterproof, and only when the seals are perfect. Those seals degrade with age, drops and previous repairs, and the IP rating is tested in clean water – salt water, pool water and drinks are far more corrosive. A water-resistant phone can still suffer internal liquid damage.

What warranty comes with a water-damage repair?

Liquid and board-level repairs at celltech carry a 120-day guarantee. That's shorter than the 27-month guarantee on standard parts such as screens and batteries – reflecting the unpredictable nature of liquid damage – but still longer than the typical 90-day manufacturer repair warranty.
