An SIA licence is a legal requirement for many front line security jobs, such as door supervisor, security guard and CCTV operator. Working in a licensable role without a licence is a criminal offence, and a conviction can lead to a fine, up to six months in prison, or both. So a refusal can feel like a real setback.
If your SIA licence has been rejected, here is the short answer. The Security Industry Authority (SIA) may refuse an application if you do not pass its checks, for example if you do not have the right to work in the UK, your criminal record suggests a risk to the public, you seem unsuitable for another reason such as dishonest behaviour, or the SIA cannot confirm who you are. What you can do next depends on your decision letter.
A refusal does not mean every future application will fail. This guide explains what a refusal means, why it may happen, what to do next and how to avoid common mistakes. It is general information, not legal advice.

A refusal means the SIA has decided, after its checks, not to grant the licence you applied for. It is not the same as an application that is simply taking a while, or one where the SIA needs more information from you.
You may come across four stages:
Read your letter slowly, because it tells you which stage you are at and which deadlines apply. Rules also change. The SIA updated its licensing criteria on 1 December 2025, and the current criteria are published in the May 2026 edition of its Get Licensed booklet. Older advice online may no longer be correct, so if you are unsure about anything, check the SIA’s own guidance rather than guessing.
The points below are possible causes. They are not a full list, and none of them leads to refusal in every case. Your decision letter is the only reliable guide to your own situation.
Small mismatches can cause problems. As an illustrative example, a middle name might appear on your passport but not on your application, or you might enter an old address by habit. Check every detail before you submit.
You must show documents that prove who you are. Illustrative problems include expired documents, names that do not match across documents, or damaged ID. The SIA’s guidance explains which documents it accepts, so follow the current instructions.
The SIA checks your UK criminal record when you apply, and it may ask for overseas checks in some cases. Having offences on your record does not always stop you getting a licence. The outcome depends on factors such as how serious and how recent the offences are. The SIA’s criminal record indicator is a helpful pre-check, but it does not guarantee the result of the real check. If your record is complicated, check the Get Licensed criteria before you pay for training or an application.
For a front line licence, you must be 18 or over, pass identity and criminal record checks, hold the right licence-linked qualification and have the right to work in the UK. If your right to work has expired or is still being decided, this can affect your application.
You need a licence-linked qualification before applying for a front line licence, but not for a non-front line or key holding licence. The SIA advises you not to apply until your qualification appears under “My qualifications” in your SIA online account. Qualifications may also have time limits, so confirm the current rules for your licence type.
The SIA may also refuse if organisations it works with, such as the police, provide information suggesting you are unsuitable. For the full criteria, use the Get Licensed booklet.
Try not to react straight away. Work through these steps.
Do not assume an appeal is always available, or that a new application is always the right move. Your letter and the SIA’s guidance decide that.
A few simple checks can save time and money. The application fee is not refunded if the SIA refuses your application.
You can find the full application steps on the Apply for an SIA licence page.
Sometimes, but it depends on why you were refused and on the rules at that time. The official guidance we reviewed does not give one rule for every situation, so please check your letter and the SIA’s guidance before you act.
It helps to keep three things apart:
If your refusal was linked to your criminal record, the SIA cannot change what is on your record, and the age and seriousness of offences are part of its criteria. No one can promise that a later application will be approved.
If you are exploring training for a security career, Bright Learning Centre in Leicester offers SIA courses. If you have questions about training, you can contact us.
Please note that training does not guarantee SIA licence approval. Bright Learning Centre cannot overturn a refusal or make licensing decisions. Those belong to the SIA and the courts.
A refusal is stressful, but the letter usually tells you what you need: the reason, the type of refusal and any deadlines. Start there, compare it with the SIA’s current guidance, and choose the step that fits, whether that is correcting a mistake, sending evidence, getting legal advice or preparing better for a future application.
If training is part of your plan, you are welcome to explore our SIA courses or get in touch.
Your decision letter gives the reason. Common examples include no right to work in the UK, a criminal record suggesting risk to the public, other unsuitability such as dishonest behaviour, or identity concerns. Reasons vary, so rely on your own letter rather than general lists.
Sometimes. It depends on the reason for refusal and the current criteria. Fixing a factual error is different from reapplying after an eligibility-related refusal. Check your letter and the Get Licensed booklet first. A new application needs a new fee, and approval is never guaranteed.
It can, but not automatically. You may still get a licence with offences on your record. The SIA looks at factors such as seriousness and how recent the offences are. Its criminal record indicator offers a guide, not a guarantee.
Often, but the route depends on your stage. If the SIA intends to refuse, you can appeal to the SIA before the decision is final. After it takes effect, you can appeal to a magistrates’ or sheriff court. Your letter explains your options.
The guidance gives 21 days for an appeal to the SIA after an intention to refuse, and 21 days for a court appeal after the decision takes effect. The SIA may allow more time in certain situations, so tell it early if you need it. Always confirm the dates in your own letter.
They can cause problems. Mismatched names, dates of birth or addresses may affect identity checks, and not being who you say you are is a stated ground for refusal. Not every small error leads to refusal. Check your details before submitting, and send evidence if the SIA has recorded something wrongly.
For a front line licence, no. You need a licence-linked qualification before you apply, although non-front line and key holding licences do not require one. Check which licence you need and make sure your qualification shows in your SIA online account.
Read the SIA’s message carefully and send the documents it asks for, within the time given. The SIA may ask for proof of address if its automatic address check fails. Use valid, matching documents. If you are refused, follow the appeal steps in your letter.
There is no single answer. A new application is judged against the criteria in force at that time. A refusal caused by a fixable error may be different from one linked to a criminal record. The guidance we reviewed does not describe an automatic ban, but nothing is guaranteed.
