Xiaomi & Redmi Repair by Post UK 2026 — Send Anywhere, Get It Fixed
Direct answer: Yes — celltech accepts Xiaomi, Redmi and Poco phones for repair from anywhere in the UK by post. Book online, follow the completed-order carriage instructions, and check the repair-specific guarantee and return terms before payment. If posting a Mix Fold or Mix Flip, pad it so it cannot fold or shift, protecting the inner display and hinge.
Back up important data where possible. Many repairs do not require a reset, but no repair is risk-free for data.
Why post your Xiaomi or Redmi for repair?
Think about how the phone reached you in the first place — ordered online, delivered to your door, never once seen on a shelf. Repair follows the same logic. There was never a shop network to keep Xiaomi, Redmi and Poco spares on hand, the family runs to dozens of models a year, and the technicians who actually know it work online rather than behind a counter. Send the handset and it joins a bench that fixes the whole family every week; quote a published price before any work starts and the decision to post it stops feeling like a gamble.
How Xiaomi mail-in repair works
- Open a booking at /repair/phone/xiaomi and note the repair reference you are given.
- Wrap and box the phone as set out below — with a foldable, immobilise the hinge first.
- Send it using suitable tracked postage arranged from the order instructions, with compensation cover appropriate for the handset's value.
- Confirm the price — we examine the phone and, unless it was agreed at booking, give you the exact figure before any work happens.
- Get it back repaired, returned under the order terms, with the guarantee held against your reference.
How to pack a Xiaomi or Redmi safely for posting
- Roll the phone in bubble wrap and place it in a rigid box — a padded envelope by itself will not absorb a drop.
- Don't reuse the retail box; branded packaging tells everyone in the chain what is inside.
- Eject the SIM, gather up stray cables, and keep the SIM card on you.
- Take a backup before the phone is sealed in.
- Foldable note: a Mix Fold or Mix Flip must be packed so it can neither hinge shut nor slip, which keeps the crease, the inner panel and the hinge mechanism safe.

Royal Mail Special Delivery — what you need to know
Posting a phone you only ever bought online makes choosing suitable postage doubly worth getting right. Select a carrier that accepts the device and installed battery, with tracking and compensation cover appropriate for the handset's value. Royal Mail Special Delivery may be one option if its current terms fit your parcel; the full rundown is in our Royal Mail Special Delivery device-shipping guide.
Is your data safe?
A Xiaomi or Redmi screen or battery repair normally avoids planned logic-board or storage work, but testing needs depend on the fault and no repair is risk-free for data. We confirm any passcode or reset requirement before proceeding. Back up first whenever possible.
Xiaomi-family repairs available by post
By post we carry out screen replacement, battery replacement, charging-port repair, back-glass and rear-camera work, and Mix foldable inner-display work across the full Xiaomi, Redmi and Poco range. See the Xiaomi repair cost hub for prices. For how Xiaomi compares with other brands available by post, see our Android, OnePlus, Nothing and UK mail-in guide pages.
Which Xiaomi faults mail-in suits best
Across such a wide family, three faults are where posting the phone really earns its place. Screen replacement is the workhorse — everything from a budget Redmi A LCD to a Xiaomi 14 Ultra AMOLED — and it travels through the post without drama; see our Xiaomi screen replacement page. Battery replacement bites hardest on the big-capacity Redmi line, where heavy daily use shows its age first, and it is clean rear-entry work; see the Xiaomi battery replacement page. Charging-port repair starts with the inexpensive checks — cable and debris before anything else, then a daughter-board swap only if it is truly needed — so you never foot the bill for a fix the diagnosis rules out; see the Xiaomi charging port repair page.
One category deserves a heads-up before you post: anything suggesting liquid ingress or a board-level fault. Those want a bench diagnostic that may sit at the 120-day tier rather than a straightforward component swap, so message us first — and if a phone proves to be carrying damage that cascades, we will weigh it honestly against the beyond-economical-repair line rather than charge you for a repair that cannot hold.
What happens to your Xiaomi once it arrives
A mail-in repair is only as sound as the way it is taken in, and the reason ours holds for the sprawling Xiaomi family is that the path is identical no matter which sub-brand turns up. When the tracked parcel is signed for, the phone is bound to your reference, photographed as received, and added to the bench queue. Before any tool is picked up there is a diagnostic: the technician checks that the fault matches your description, looks for the secondary damage a knock can hide, and only then puts a figure on it. Where the price agreed at booking still covers the work, we press on; where the inspection surfaces something else, we stop and tell you before opening the phone.
The repair itself answers to the fault. A Redmi Note screen is warmed open and its AMOLED or LCD panel separated and re-laminated; a large Redmi cell is freed with controlled heat and exchanged for an OEM-grade equivalent; a worn USB-C port is usually resolved with a daughter-board swap. With the job done the phone runs a fault-specific function check before return under the order terms. Many standard repairs do not require a passcode, but testing needs are confirmed case by case and no repair is risk-free for data. The wider picture lives in our how mail-in repair works guide.
How mail-in compares with the alternatives
Book online, arrange suitable tracked inbound postage using the order instructions, and review the return-delivery terms confirmed for the order.
What happens once your Xiaomi or Redmi arrives — and what we test before it leaves
When the parcel arrives, the handset is booked to your repair, photographed and identified to the right sub-brand before a price is quoted — a Redmi Note 14 Pro is not a Xiaomi 14 Pro. Diagnosis then identifies the failed component and confirms the price before work starts. The part grade is agreed with you first: OEM-grade or genuine.
The repair is bench work shaped to the device: a flat Redmi OLED parted cleanly on a heated platen, a cell swapped for a cycle-rated equivalent, a worn USB-C port micro-soldered rather than treated as disposable. Before it ships, every Xiaomi and Redmi clears a function pass matched to the work and then returns under the order terms. That verification stands behind the tiered guarantee and returns the same handset rather than a refurbished swap; back up first because no repair is risk-free for data.
Frequently asked questions
Can I send my Xiaomi or Redmi for repair by post from anywhere in the UK?
Yes — the mail-in service covers the entire UK. Book your reference, follow the completed-order inbound instructions, and review the order-specific return method and any charge before payment.
How do I pack a Xiaomi phone safely for posting?
Bubble-wrap it in a rigid box rather than the branded one, take out the SIM and cables, run a backup, and immobilise any foldable — a Mix Fold or Mix Flip — so it cannot fold or slide while in transit.
Is Royal Mail Special Delivery covered for phone repairs?
Yes — compensation cover is included as standard and can be increased for a higher-value handset. Check Royal Mail's current limit before posting and buy enough to match what the phone is worth. The parcel is tracked and needs a signature on delivery.
Will my data be safe if I post my Xiaomi?
Standard screen or battery work normally avoids planned storage access, but testing requirements depend on the fault and no repair is risk-free for data. We confirm any passcode or reset requirement before proceeding, and you should back up beforehand.
What happens if celltech can't fix my Xiaomi?
Standard component repairs are paid on completion, so a job we cannot finish does not proceed without your approval. Board-level work carries a diagnostic fee that is credited against the repair if you go ahead, and we always set out the honest alternatives.
Do I need to remove my SIM card before posting?
Yes — take out the SIM and any storage card and keep them safe. Doing so also leaves the phone powered off for the journey.
Do you repair Poco and Redmi Note models by post too?
Yes — the whole Xiaomi family is in scope, from the Poco performance line to the high-volume Redmi Note series. The Redmi Note screen page breaks that down.
