Phone & Tablet Repair Cardiff: celltech Mail-In Service
Cardiff is the beating heart of Welsh technology, commerce, and culture. From the startups clustering around Cardiff Bay's innovation quarter to the students filling Cathays and Roath, from the shoppers on Queen Street nursing cracked screens to the professionals in Canton who can't afford a day without their phone — device repair is a constant need in Wales's capital. But specialist repair shops with genuine expertise and proper equipment are harder to find than they should be.
Repair timing depends on the device, fault, parts, testing, and carrier journey. Use the repair-specific estimate and order updates.

Common Repairs from Cardiff
Cardiff customers send us a consistent range of repairs:
Screen Repairs
Cracked screens dominate our Cardiff repairs, just as they do nationwide. iPhone displays shattered from drops on Castle Street, Samsung screens with spider-web cracks from the Principality Stadium crush, iPads with dead touch zones that won't register input — we replace them all with manufacturer-quality parts. Full touch sensitivity, original display quality, and biometric functions like Face ID are all restored.
Battery Replacements
South Wales's damp climate and temperature swings aren't kind to lithium-ion batteries. After 18-24 months of daily use, many phones lose enough capacity to become unreliable by mid-afternoon. We fit genuine-spec replacement batteries with proper calibration, bringing your phone back to genuine all-day performance.
Charging Port Repairs
A phone that only charges at a specific angle, charges intermittently, or refuses to charge at all needs more than a blast of compressed air. We replace the entire charging assembly — port, flex cable, and associated components — with a brand-new unit. Permanent fix, not a temporary workaround.
Water Damage Treatment
Cardiff sees its share of rain, and phones suffer accordingly. Rainy commutes, puddled pavements, and the occasional dropped-in-the-sink disaster all end up on our workbench. We perform full ultrasonic cleaning of the logic board, identify and replace corroded components at IC level, and recover devices that most shops would declare beyond saving.
Camera Repairs
Blurry photographs, black viewfinder screens, or a camera module that rattles audibly. We replace the full camera assembly — front or rear — using OEM-grade components that restore your device to its original photographic capability.
Why Choose celltech from Cardiff?
You could visit a local repair shop, so why choose a UK-wide mail-in specialist instead?
- Specialist-grade workshop — Microsoldering stations, ultrasonic cleaning equipment, calibrated screen testing rigs. Our workshop is equipped for repairs that high-street shops physically cannot perform.
- Transparent pricing — Diagnosis on standard repairs is free; applicable specialist, third-party and return charges are confirmed before work.
- OEM-grade parts only — We use manufacturer-quality screens, batteries, and components. Cheap aftermarket parts might save a few pounds upfront but fail within months — we don't stock them.
- Repair-specific guarantee — covered standard repairs carry the stated 27-month tier; connector, board-level and liquid-damage work use their published tiers.
- Documented mail-in process — Booking, packaging, assessment and order updates follow clear steps from start to finish.
Our Warranty
Every celltech repair is backed by comprehensive warranty cover:
- 27 months — Screen, battery, camera, speaker, and button repairs
- 9 months — Charging port and headphone jack repairs
- 120 days — Water damage treatment and board-level microsoldering
If a warranted part fails, contact us before posting. We will confirm eligibility and the applicable work and carriage arrangements under the warranty and order terms.
Frequently Asked Questions
How should I send a device from Cardiff?
Follow the private destination and packing instructions supplied for the completed order. Choose a carrier and service that accepts the device and provides suitable tracking and compensation under its current terms.
Do you serve areas outside Cardiff?
Absolutely. Our mail-in service works from any Post Office in the UK. We regularly receive devices from Cardiff Bay, Canton, Roath, Penarth, Barry, Newport, Bridgend, Swansea, Merthyr Tydfil, and across the whole of South Wales. If there's a Post Office near you, you can use the service.
Is it safe to post my phone?
Choose a current inbound service with tracking and compensation appropriate to the device's value. Check the carrier's target, signature and claim terms before posting. For packing and risk guidance, read our mail-in safety guide.
What if I need my phone back urgently?
Repair timing depends on the device, fault, parts, testing, and carrier journey. Use the repair-specific estimate and order updates.
Can I send an iPad or tablet as well as a phone?
Yes. We repair all iPad models, Samsung tablets, and other Android tablets. The mail-in process is identical — just use a slightly larger box and extra bubble wrap for tablet-sized devices. The same warranty coverage applies.
