Quick Reference
Warranty at a Glance
Our 27-month warranty applies to most standard repairs. However, certain repair types have reduced warranty periods due to their technical complexity or inherent risks. Here's the summary:
| Repair Category | Warranty | Why? |
|---|---|---|
| Screens, batteries, cameras, speakers, buttons | 27 months | Straightforward replacements with predictable outcomes |
| Charging ports, connectors | 9 months | Subject to daily mechanical stress from plugging/unplugging |
| Board-level / microsoldering | 120 days | Microscopic work with inherent uncertainties |
| Liquid damage recovery | 120 days | Hidden corrosion can be progressive and unpredictable |
What the asterisk (*) means: When you see "27-month warranty*" on our website, the asterisk indicates that reduced warranty periods apply to charging ports (9 months), board-level repairs (120 days), and liquid damage recovery (120 days). All other repairs receive the full 27-month coverage.
Warranty Overview
The celltech 27 Month Fix Guarantee™
At celltech, we stand behind our work with the UK's most comprehensive repair warranty. Our tiered warranty system provides up to 27 months of protection — more than double the industry standard — because quality repairs deserve quality protection.
Our warranty is designed to be fair to both customers and our business. We want you to have complete confidence in our repairs, whilst protecting against abuse that would ultimately drive up prices for everyone.
Key principles:
- Different repair types carry different warranty periods based on their technical nature
- Warranty covers both parts and labour at no additional cost
- Free diagnosis for all warranty claims
- Clear, transparent terms with no hidden exclusions
The warranty period begins from the date of repair completion or device collection/delivery.
Parts Quality Promise
The foundation of any warranty is the quality of work it covers. At celltech, we invest in parts quality so we rarely need to honour warranty claims in the first place.
Our parts sourcing standards:
- Premium-grade components — We use OEM-equivalent or genuine parts, never cheap knockoffs
- Vetted suppliers — Every supplier is tested and evaluated before we stock their parts
- Batch testing — Random parts from each shipment are tested before entering our inventory
- Traceability — Every part is tracked from supplier to installation
Why This Matters
Cheap parts fail. They're why many repair shops only offer 3-month warranties — they know their parts won't last. We pay more for quality parts because it means fewer returns, happier customers, and a warranty we can actually stand behind.
Screen quality tiers:
- Premium (Standard) — High-quality aftermarket with OEM-equivalent performance
- OEM (Available) — Genuine manufacturer screens for those who want exact match
We'll always tell you which grade of part we're using before the repair begins.
Pre-Delivery Testing
Every device undergoes comprehensive testing before it leaves our workshop. This isn't a quick glance — it's a systematic check of all repaired and related functions.
Our testing checklist includes:
- Visual inspection — Fitment, alignment, no gaps or debris
- Touch response — Full screen touch grid test, edge detection, 3D Touch/Haptic Touch
- Display quality — Colour accuracy, brightness levels, no dead pixels or bleeding
- Connectivity — Wi-Fi, Bluetooth, cellular signal, GPS
- Sensors — Proximity, ambient light, Face ID/Touch ID, accelerometer
- Audio — Speakers, microphones, earpiece
- Cameras — Front and rear, flash, focus, stabilisation
- Battery — Health reading, charging test
- Buttons — Power, volume, mute switch, home button
Tested By celltech
You'll receive your device only after it passes our full testing protocol. If something isn't right, we fix it before you leave — not after.
Warranty Tiers
We offer four warranty tiers based on repair complexity and technical risk. This tiered approach allows us to offer industry-leading protection on standard repairs whilst being realistic about the inherent challenges of complex component-level work.
| Repair Type | Warranty Period | Covers |
|---|---|---|
| Standard Repairs | 27 Months | Screens, batteries, cameras, speakers, buttons |
| Connector Repairs | 9 Months | Charging ports, headphone jacks, dock connectors |
| Board-Level Repairs | 120 Days | Logic board, microsoldering, chip replacement |
| Liquid Damage Recovery | 120 Days | Water damage diagnosis and repair |
Standard Repairs (27 Months)
Our flagship warranty covers the vast majority of repairs we perform. This includes:
- Screen replacements — LCD, OLED, and digitiser assemblies
- Battery replacements — All device types (see battery-specific terms below)
- Camera replacements — Front and rear camera modules
- Speaker and microphone — Ear speakers, loudspeakers, microphones
- Button repairs — Power, volume, home buttons, and flex cables
- Vibration motors — Taptic engines and vibration modules
- Antenna and connectivity — Wi-Fi, Bluetooth, and cellular antennas
- Sensor replacements — Proximity, ambient light, Face ID, Touch ID
Industry-Leading Protection
27 months is more than double what most UK repair shops offer. We can offer this because we use quality parts and employ skilled technicians who do the job right the first time.
Connector Repairs (9 Months)
Charging ports and other connectors are subject to daily mechanical stress from plugging and unplugging. Our 9-month warranty reflects this reality whilst still providing substantial protection.
Covered connectors:
- Lightning ports (iPhone, iPad)
- USB-C ports (MacBook, iPad Pro, modern devices)
- MagSafe charging boards
- Headphone jacks
- Dock connector assemblies
Important Conditions
Connector warranty is void if the damage was caused by:
- • Excessive force when inserting or removing cables
- • Non-genuine or low-quality chargers — always use Apple-certified or manufacturer-approved accessories
- • Foreign objects inserted into the port
- • Liquid ingress through the charging port
We recommend using only genuine or MFi-certified (Made for iPhone) accessories to protect both your device and your warranty coverage.
Board-Level Repairs (120 Days)
Board-level and microsoldering repairs involve working with microscopic components on the logic board itself. These repairs are highly technical and involve inherent uncertainties that make longer warranties impractical.
What qualifies as board-level:
- Logic board repairs — MacBook, iPhone, iPad main boards
- Microsoldering — Component-level chip replacement and reballing
- Power management IC — Charging chips, Tristar, Hydra
- Audio IC repairs — iPhone audio disease, no sound issues
- Baseband and modem — No service, searching issues
- Touch IC — Touch disease, ghost touch from board issues
- GPU/CPU issues — Graphics failures, thermal issues
- Memory and storage — NAND replacement, data recovery related
Why 120 days? Board-level repairs work with components that may have been stressed by the original fault. Whilst we thoroughly test every repair, hidden damage can sometimes manifest weeks later. Our 120-day period provides meaningful protection whilst being honest about the technical realities.
Industry Context
Most UK repair shops offer 30-90 days for board-level work. Our 120-day warranty demonstrates our confidence whilst remaining sustainable.
Liquid Damage Recovery (120 Days)
Liquid damage creates unique challenges. Corrosion can be hidden and progressive, meaning a device that tests perfectly today may develop issues weeks later as corrosion spreads.
Our liquid damage service includes:
- Ultrasonic cleaning of the logic board
- Corrosion removal and treatment
- Component-level diagnosis and repair
- Full functional testing
What the 120-day warranty covers:
- Failure of components we repaired or cleaned
- Issues directly related to our repair work
- Parts we replaced during the repair
What it does not cover:
- New liquid exposure after our repair
- Corrosion progression in areas we did not treat
- Pre-existing damage that was not apparent during initial diagnosis
- Components that were functioning but later failed due to hidden corrosion
Honest Expectations
Liquid damage repair is never guaranteed. We will always give you an honest assessment of your device's condition and long-term prognosis before you commit to repair.
What's Covered
Across all warranty tiers, we cover:
- Parts defects: If a replacement part fails under normal use
- Workmanship issues: If our repair work causes a fault
- Related failures: Issues directly resulting from the original repair
- Labour costs: All warranty work is performed free of charge
- Diagnosis: Free assessment for all warranty claims
Warranty claims are assessed and processed at no cost to you. If we determine the issue is covered, we will repair it free of charge.
What's Not Covered
Our warranty does not cover:
- Physical damage: Drops, impacts, cracks, bends, or crushing occurring after repair
- Liquid damage: Water or other liquid exposure after repair (even on water-resistant devices)
- Software issues: Operating system bugs, app problems, data loss, firmware corruption
- Third-party modifications: Damage from repairs or modifications done elsewhere after our repair
- Tampering: Evidence of unauthorised opening or repair attempts
- Normal wear: Expected degradation from regular use (scratches, minor dents)
- Accessories: Chargers, cables, cases, and other accessories
- Misuse: Damage from improper handling, extreme temperatures, or negligence
- Unrelated faults: Issues with components we did not repair
- Cosmetic issues: That do not affect functionality (minor dust, alignment variations)
Fair Use Policy
Our warranty is intended to protect customers against genuine defects and workmanship issues. To ensure we can continue offering industry-leading protection, we reserve the right to decline or limit claims in cases of:
- Excessive claims: Multiple claims on the same device suggesting misuse or undisclosed damage
- Fraudulent claims: Misrepresenting damage or circumstances
- Commercial use: Devices used in commercial rental, resale, or trade operations without disclosure
- Modified devices: Jailbroken, rooted, or hardware-modified devices
We assess every claim individually and give customers the benefit of the doubt. Genuine issues will always be resolved fairly.
What If We Damage Your Device?
We understand this is a real concern. You're trusting us with an expensive device, and accidents can happen even to skilled technicians.
Our Collateral Damage Promise
If we cause damage to your device during repair — whether it's a cable we accidentally tear, a component we damage, or any fault that wasn't there before — we will fix it at no cost to you.
This includes:
- Components damaged during disassembly or reassembly
- Cables, connectors, or flex ribbons accidentally torn
- Screws stripped or standoffs damaged
- Any new fault that appears immediately after repair that wasn't present before
How we handle it:
- We document your device's condition before starting any repair
- If we cause damage, we tell you immediately — no hiding it
- We repair the damage at our cost, even if it means ordering parts
- If we cannot repair it, we discuss fair compensation
We've been repairing devices since 1999. Collateral damage is rare, but when it happens, we own it.
Feature Preservation
Modern devices have features that can be affected by repairs. We want you to know what to expect.
iPhone screen replacements:
- True Tone: We calibrate True Tone when possible. If using OEM screens, True Tone is preserved. Premium aftermarket screens may require re-pairing.
- Face ID: Fully preserved when we transfer your original earpiece/sensor assembly
- Auto-brightness: Preserved with proper sensor transfer
Touch ID (Home button):
- Touch ID only works with your original home button
- We always transfer your original button when possible
- If the original button is damaged, Touch ID cannot be restored (Apple limitation)
Battery health reporting:
- iPhone 15+ and some iPhone 14 models: Battery health fully restored with genuine/supported batteries
- Older iPhones: May show "Unknown Part" message but battery functions normally
- This is an Apple software limitation, not a parts quality issue
We'll always tell you before the repair if any features might be affected.
Your Data
Back up your device before any repair. This is essential.
Data Disclaimer
Whilst we take every precaution to preserve your data, celltech cannot be held responsible for data loss during repair. Some repairs require factory resets, and unexpected issues can occur.
Why data loss can happen:
- Board-level repairs: May require chip replacement that erases data
- Liquid damage: Storage chips may be corroded or damaged
- Software issues: Some repairs require DFU restore
- Passcode-locked devices: We cannot bypass your passcode to back up data
Before your repair:
- Back up to iCloud or your computer
- Note your Apple ID and password (you may need them after)
- Disable Find My iPhone if possible
- Tell us if data recovery is your priority — it may change our approach
If your device doesn't turn on and you need data recovered, ask us about our data recovery service before standard repair.
Real-World Examples
To help you understand what's covered, here are common scenarios:
✓ COVERED:
- "My new screen developed a dead pixel after 3 months" — Parts defect, covered
- "The battery we replaced now shows 75% health after 6 months" — Below 80% threshold, covered
- "Touch stopped working on part of the screen we replaced" — Parts/workmanship issue, covered
- "The charging port you fixed stopped working again" — Related failure, covered
- "My phone won't turn on after your board repair" — Workmanship issue, covered (within 120 days)
✗ NOT COVERED:
- "I dropped my phone and cracked the new screen" — Physical damage after repair
- "My speaker stopped working but you only replaced the battery" — Unrelated component
- "I spilled coffee on it after you fixed the screen" — Liquid damage after repair
- "The screen works but I don't like the colour tint" — Cosmetic preference (but we'll discuss options)
- "My charging port broke again" (using cheap cables) — User-caused damage, not defect
Grey areas? We'll discuss them honestly. If there's genuine doubt, we give you the benefit of it.
If You Disagree With Our Assessment
We aim to be fair, but we know disagreements can happen. Here's how we handle them:
Step 1: Talk to us
If you disagree with our warranty decision, tell us why. We'll review the case again with fresh eyes. Sometimes we miss things or don't have the full picture.
Step 2: Manager review
If you're still not satisfied, ask for a manager review. A senior technician will re-examine your device and our decision.
Step 3: External options
If we still can't reach agreement, you have options:
- Citizens Advice: Free, impartial guidance on your consumer rights
- Trading Standards: For complaints about unfair practices
- Small Claims Court: For disputes under £10,000
- ADR (Alternative Dispute Resolution): Independent mediation
We'd rather resolve issues directly — it's faster and better for everyone. But we respect your right to escalate if needed.
No Fix, No Fee Diagnosis
Free Diagnosis Promise
We will diagnose your device and provide a quote at no cost. If you decide not to proceed with the repair, you pay nothing.
How it works:
- Bring your device in or send it to us
- We diagnose the issue and identify what needs repair
- We provide a clear quote with no hidden fees
- You decide whether to proceed
- If you say no, you collect your device — no charge
Exceptions:
- Data recovery: Complex data recovery may require a diagnostic fee (always quoted upfront)
- Board-level diagnosis: Extensive microsoldering diagnosis may incur a fee if you don't proceed (always quoted upfront)
We'll always tell you if any fees apply before we start work.
We'll Tell You If It's Not Worth It
Not every device should be repaired. Sometimes the honest answer is "don't spend money on this."
No Sales Pressure
We'd rather lose a sale than let you waste money on a repair that doesn't make sense. If your device isn't worth fixing, we'll tell you — and explain why.
When we might advise against repair:
- Repair cost exceeds device value: If a £200 repair on a £150 phone doesn't make sense, we'll say so
- Multiple failing components: Sometimes one fix reveals another problem, then another — we'll give you the full picture
- Age and obsolescence: If your device won't receive software updates or parts are scarce, you should know
- Low success probability: For liquid damage or board-level repairs, if the odds aren't good, we tell you upfront
We've been doing this since 1999. Our reputation matters more than any single repair fee. We'd rather you leave without paying and come back next time, than feel you were pushed into a repair you didn't need.
Goodwill Repairs
Warranties have limits. Life doesn't always fit neatly into policy documents.
Our approach: We make exceptions on a case-by-case basis when we feel it's the right thing to do.
Examples where we've helped beyond policy:
- A screen failed at 28 months (just past 27-month warranty) — we replaced it anyway
- A customer couldn't afford a repair after losing their job — we offered a payment plan
- A charging port issue returned after warranty, but it was clearly the same fault — we fixed it free
- A repair took longer than expected — we discounted the bill
We don't advertise these policies because they're not guaranteed. But if you're in a difficult situation or something feels unfair, talk to us. We're humans, not a policy document.
The celltech Approach
We encourage you to shop around. The difference between repair shops becomes clear when something goes wrong. We want to be the shop you come back to — and recommend to others.
All Repairs Done In-House
Every repair is performed at our 353 Warwick Road, Solihull, B91 1BQ workshop by our own technicians. We don't outsource.
Why this matters:
- Faster turnaround: No shipping to third parties, no waiting for their schedule
- Direct accountability: The person who fixes your device works for us
- Consistent quality: We control the entire process
- Your device stays local: It doesn't travel to unknown locations
Our parts sourcing:
- Direct relationships with established suppliers
- No random eBay purchases or unknown middlemen
- Batch-tested inventory ready to go
- If a part is defective, we have backups — your repair isn't delayed
When other shops advertise "board-level repair," ask if they actually do it on-site or send it away. We do it here, in front of you if you want to watch.
Battery Specific Terms
Battery replacements are covered under our standard 27-month warranty with the following specific terms:
Capacity guarantee:
- Phones and tablets: Battery health must remain above 80%
- Laptops and other devices: Battery health must remain above 85%
If your battery health drops below these thresholds within the warranty period under normal use, we will replace it free of charge.
What affects battery health:
- Charge cycles (normal degradation)
- Extreme temperatures (hot cars, freezing conditions)
- Overnight charging habits
- Using non-certified chargers
- Running battery to 0% frequently
Normal capacity loss from regular use is expected and is not a defect. We use Apple's Battery Health feature (or equivalent) as the measurement standard.
Water Resistance Disclaimer
Important Notice
Opening a device for repair may compromise its original water resistance rating. This applies to all devices, regardless of their IP rating.
What this means:
- Your iPhone's IP68 rating may not be maintained after screen or battery replacement
- Water resistance seals degrade over time and with each opening
- We do not guarantee water resistance after any repair
- Liquid damage after repair is not covered by warranty
We recommend treating all repaired devices as non-water-resistant and taking appropriate precautions. This is industry-standard practice and applies to all repair providers, including Apple.
