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 a repair reference online, send your phone via Royal Mail Special Delivery (tracked and insured), and it is returned repaired with a 27-month guarantee on screens and batteries — more than double the 12 months most independents offer. No local shop required. If posting a Mix Fold or Mix Flip, pad it so it cannot fold or shift, protecting the inner display and hinge.
Xiaomi-family phones are bought overwhelmingly online in the UK, which quietly decides how they get repaired: with no high-street retail network behind them, there is rarely a local shop that stocks Xiaomi, Redmi and Poco parts, so the catalogue you bought from a screen is the same catalogue you fix through the post. Mail-in is the natural route, not a reluctant second choice. Exactly how the celltech Xiaomi mail-in service works, how to pack a handset (a Mix Fold or Mix Flip needs the hinge and inner display immobilised), and how your data stays untouched are below. For prices, see our Xiaomi repair cost UK hub.
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 Special Delivery through Royal Mail, tracked and insured, with the cover raised if the handset warrants it (check Royal Mail's current limits as you buy).
- 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 tracked and insured, 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 the right postage doubly worth getting right. We steer Xiaomi owners to Special Delivery because it tracks the parcel through every handover, takes a signature at the door, and folds in compensation cover you can raise for a dearer model such as a Mix Fold. Check Royal Mail's current compensation cap before you commit and pay for enough to match the handset's value; the full rundown is in our Royal Mail Special Delivery device-shipping guide.
Is your data safe?
Yes — a Xiaomi or Redmi screen or battery repair is work on the casing and the chassis, not the logic board, so the part of the phone holding your photos, chats and accounts is never opened up or read. Most jobs do not ask for your passcode at all, and we will not wipe a handset back to factory unless you have told us to. Backing up first is just plain common sense before any device changes hands.
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 free 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 function check — touch, brightness, charge behaviour, fingerprint — before it heads home tracked and insured with the guarantee logged. Standard repairs never require your passcode, and your data is never opened. The wider picture lives in our how mail-in repair works guide.
How mail-in compares with the alternatives
Faced with a broken Xiaomi, an owner is really choosing between three routes, and for most the post comes out on top. The local shop is handy but seldom carries Xiaomi, Redmi or Poco spares — too many models, demand too thinly spread outside the big cities — so you wait on an order or settle for a generic aftermarket part. Xiaomi's own UK service exists yet runs narrow and slow, and out of warranty it usually costs more than an independent specialist. celltech's mail-in bench fixes the family week after week, charges a published fixed price, and carries the phone both ways tracked and insured, with no need to live anywhere near us. If the journey itself worries you, our is it safe to post a phone guide tackles it directly, and the packing guide covers the practical detail.
What happens once your Xiaomi or Redmi arrives — and what we test before it leaves
When the tracked, insured parcel lands, the handset is booked to your repair, photographed on arrival, and identified to the right sub-brand before a price is quoted — because a phone badged Redmi or Poco is priced on its own line rather than the flagship Xiaomi tariff, and a model-number collision (a Redmi Note 14 Pro is not a Xiaomi 14 Pro) is exactly the slip a careful check heads off. The free diagnostic then pins the fault to one component — screen, battery, port or board — and confirms the exact price from our live list before work starts. The part grade is agreed with you up front: OEM-grade or genuine, never an ungraded copy that would dim an OLED you stare at all day.
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 — display uniformity and touch on a screen, a clean seal and honest charge reporting on a battery, a stable connection on a port — and only then returns under tracked, insured cover. That final verification is what stands behind the tiered guarantee, and it is what lets us send back the very handset you posted, data and fitted case intact, rather than a refurbished swap.
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, post the phone tracked and insured by Royal Mail Special Delivery, and we send it back the same way once the repair is finished.
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?
Yes — a standard screen or battery repair never touches the logic board, your data is not read, your passcode is rarely needed, and no factory reset takes place without your explicit consent. Back up beforehand as a sensible habit.
What happens if celltech can't fix my Xiaomi?
Standard component repairs are paid on completion, so a job we cannot finish costs you nothing. 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.
