TL;DR
- Report the theft to the police immediately to obtain a crime reference number; this is required by virtually all mobile insurers.
- Contact your network operator to bar the SIM and, if possible, block the IMEI to prevent unauthorised use.
- Insurers will require the crime reference number, IMEI, proof of purchase, and policy details to process a claim.
- Claim timelines vary by insurer but typically run from a few days to several weeks; excess charges apply in most policies.
- A claim can be invalidated by failure to report the theft promptly, lack of documentation, or a policy exclusion such as leaving the device unattended in a public place.
The first 24 hours after a theft
Speed matters after a mobile phone is stolen. The first priority is to contact your network operator to bar the SIM. This prevents the thief running up call charges or data usage that could complicate your account and that you might otherwise be held responsible for during the period before the bar was applied. Most operators offer 24-hour SIM barring via their customer service line or app. Note the time you reported the theft to the operator, as insurers may check whether you acted promptly to mitigate losses.
The second immediate step is to report the theft to the police. In England and Wales this can be done online at Action Fraud, in person at a police station, or by calling 101. The police will issue a crime reference number (CRN). In Scotland, report to Police Scotland; in Northern Ireland, to the Police Service of Northern Ireland. Some insurers also require a unique reference from the reporting officer. Keep all paperwork and correspondence from the police; the CRN is non-negotiable for the vast majority of mobile insurance policies.
Blocking the IMEI and protecting your data
The IMEI (International Mobile Equipment Identity) is a 15-digit number unique to your handset. You can usually find it on the original box, in a previous bill, through your network account portal, or — if you recorded it in advance — in a note kept separately from the device. Your operator can block the IMEI on UK networks, which makes the handset unable to connect to any UK mobile network regardless of which SIM is inserted. This is recorded centrally on the GSMA’s IMEI database and is shared across UK operators, making the device significantly less useful to a thief for resale.
Alongside barring and IMEI blocking, activate remote lock and wipe features if your device has them enabled and you have not already done so — for example through Find My (Apple) or Find My Device (Google). This protects personal data and accounts. Do not do anything that could be interpreted as remotely accessing the device once it has been stolen, beyond standard manufacturer-provided security features; consult your insurer if uncertain.
What insurers require to process a claim
Mobile phone insurance is offered by standalone specialist insurers, through home contents policies, through packaged bank accounts, and — as add-on products — by some network operators directly. The exact claim requirements vary by insurer and policy, but the following are near-universal: the crime reference number from the police report; the IMEI of the stolen device; proof of purchase (original receipt or emailed order confirmation); your insurance policy number and details; and confirmation from your network that the SIM was barred promptly after the theft was discovered.
Some policies additionally require a copy of the relevant network bill showing the device was in active use, photographic or documentary proof of ownership (especially for high-value handsets), and details of where and how the theft occurred. Read your policy’s claim requirements section before submitting, as omitting a required document typically delays rather than invalidates a claim, but errors in the account of the theft can have more serious consequences.
| Document / item | Where to obtain it | Required by most policies? |
|---|---|---|
| Crime reference number | Police (Action Fraud, 101, or station) | Yes — near-universal |
| IMEI number | Original box, bill, network account portal | Yes — near-universal |
| Proof of purchase | Original receipt or emailed order confirmation | Yes — near-universal |
| SIM bar confirmation | Network operator (written confirmation) | Commonly required |
| Network bill showing active use | Online account or paper bill | Sometimes required |
| Policy number and schedule | Insurer documents or bank account pack | Yes — always |
Claim timelines and excess
The time taken to process a mobile theft claim varies. Straightforward claims with all required documentation are typically assessed within a few business days to two weeks by specialist mobile insurers, though some policies stipulate longer assessment periods, particularly where the insurer needs to verify details with the police or the network. Claims through home contents insurance policies may take longer because of the general-purpose claims process. Packaged bank account insurers sit somewhere in between.
Almost all mobile insurance policies carry an excess — the amount you pay towards the claim before the insurer covers the remainder. Excess amounts vary considerably by policy type, device value, and age of policy, and are set out in your policy schedule. The replacement device provided may be new, refurbished to manufacturer standard, or a cash settlement to the current market value of an equivalent device, depending on the policy terms. Confirm which applies before submitting so you know what to expect.
What can invalidate a claim
Several circumstances can lead an insurer to decline a mobile theft claim. Failure to report the theft to the police promptly is one of the most common reasons for refusal; most policies require reporting within 24 to 48 hours of discovery. Leaving the device unattended in a public place — for example on a cafe table or in an unlocked car — may trigger a “left unattended” exclusion depending on the policy wording. Lending the device to a third party who then loses it is often not covered as theft. Claims involving a device purchased by a third party (where you are not the policy holder or the named purchaser) may also encounter problems.
Misrepresentation in the claim — whether about the circumstances of the theft, the value of the device, or ownership — is treated seriously by insurers and by the FCA, which regulates insurance in the UK. Under the Consumer Insurance (Disclosure and Representations) Act 2012, consumers must take reasonable care not to make a misrepresentation when applying for insurance or making a claim; deliberate misrepresentation can result in a claim being voided and, in serious cases, fraud proceedings.
What this means in practice
Sophie lives in Manchester and has her phone stolen from her bag on a tram on 12 April 2026. She notices the theft within ten minutes. She immediately calls her network to bar the SIM and activates remote lock through her cloud account. She reports the theft via Action Fraud online that evening and receives a CRN. She then contacts her standalone mobile insurer, noting the IMEI from the original box she kept at home, and submits the claim form online with the CRN, IMEI, proof of purchase (an emailed receipt from the retailer), and written SIM bar confirmation from her operator. The insurer confirms receipt and advises a 5-to-10 business day assessment period. After seven business days, the claim is approved subject to the policy excess. Sophie pays the excess and receives a like-for-like replacement device by post three days later.

Frequently Asked Questions
How do I claim for a stolen mobile on insurance?
Report the theft to the police first (via Action Fraud online, 101, or a police station) to obtain a crime reference number, then bar the SIM with your network operator. Contact your insurer — whether standalone mobile insurance, a home contents policy, or a packaged bank account product — and complete the claim form, attaching the crime reference number, IMEI, and proof of purchase. The insurer will assess the claim against your policy terms and timeline.
What do I need to claim for a stolen phone?
The core documents required by most mobile insurance policies are: a crime reference number from the police; the IMEI of the stolen device (found on the original box or through your network account); proof of purchase such as a receipt or order confirmation email; confirmation from your operator that the SIM was barred after the theft; and your policy number. Some insurers also request a recent bill or a written account of the circumstances of the theft.
How long does a mobile theft insurance claim take?
Timelines vary by insurer and policy type. Specialist mobile insurers typically assess a straightforward, fully documented claim within a few business days to two weeks. Home contents insurance claims may take longer due to broader processing workflows. If there are queries about the documentation or circumstances, assessment can extend further. Always submit all required documents at the outset, as incomplete claims take significantly longer to process.
What can invalidate a stolen phone insurance claim?
Common grounds for claim refusal include: failure to report the theft to the police promptly (many policies require reporting within 24 to 48 hours); leaving the device unattended in a public place, which may trigger a policy exclusion; the device being lent to a third party; or misrepresentation in the claim account. Under the Consumer Insurance (Disclosure and Representations) Act 2012, deliberate misrepresentation can void a claim and may constitute fraud.
Will my premium go up after a mobile theft claim?
Whether and by how much a premium increases following a claim depends on the insurer and policy type. Specialist mobile insurance policies may apply a no-claims loading or adjust renewal terms after a successful claim; packaged bank account and home contents insurers follow their own rating models. Insurers are required by FCA rules to treat customers fairly and to be transparent about renewal pricing. Check your renewal notice carefully and shop around if the increase seems disproportionate.
