    Services we Provide

    Illegal Workers

    If you are concerned that you are either working illegally or employing illegal workers in the UK it is highly important that you change your circumstances as soon as possible. This will help you avoid incurring severe penalties from the Home Office.

    You can be classed as an illegal worker if you do not have Leave to Remain in the UK; or if the leave you have is invalid or has ceased to have an effect. You will also be classed as an illegal worker if your leave to remain does not allow the kind of work you are involved in.

    If you are in doubt as to whether yourself or those you employ may be working illegally, you should speak with a legal expert immediately.

    Our lawyers can offer you immediate, confidential advice to help ensure that you do not incur any penalties from the Home Office. Our services include Sponsor Licence assistance, immigration consultancy and urgent work permit applications to ensure you are employing foreign workers within the law. Get in touch on 0333 363 8577 or make an enquiry online to speak to one of our lawyers now.

    You can contact our London, Manchester, or Birmingham immigration lawyers, or use the office finder to find the closest branch to you.

    Please see the FAQs section to understand the options that may be available to you.

    Frequently Asked Questions

    As of July 2016, under section 24B of the 1971 Act, an individual pledges the offence of illegal working if he or she is:

    • subject to immigration control;
    • employed in the UK;
    • disqualified from working in the UK due to his or her immigration status; and
    • at the time, has knowledge or reason to believe that they should not be working in the UK based on his or her immigration status.

    For employers, it is important to be aware of the penalties that you could be subject to should you be found to have ignored the law. As an employer, you must ensure that your employees have the right to work in the UK, and you must also ensure that your employees’ documents are valid.

    Employers are liable for their employees and could be subject to penalties if they;

    • hire workers who do not have the correct eligibility to work in the UK; or
    • have not carried out extensive employment checks prior to hiring.

    In the event that the above actions have not been carried out, the employer may receive a referral notice from the Home Office. This referral notice will notify the employer that their case is being considered and that the investigation could result in the employer having to pay a fine of up to £20,000 per illegal worker.

    The employer may subsequently receive a Civil Penalty notice and have up to 28 days to respond to this notice. The notice will detail how to pay the fines, what the next steps are, and also how to appeal the decision (see next FAQ).

    Your business’s details could also be published by Immigration Enforcement as a warning to other businesses not to employ illegal workers.

    It is highly important that, as an individual migrant worker, you understand the penalties you could face should you be found to have ignored the law.

    You could face a six-month prison sentence with an unlimited fine if you are found working without the rightful paperwork. In addition, any income you earn as a result of working illegally may be seized by the Home Office.

    If you are worried that you might be working illegally in the UK then it is highly advisable that you seek the guidance of an immigration specialist.

    Working illegally in the UK can have a negative impact on any future applications you may make for a UK visa or work permit.

    If you get in touch with one of our highly-equipped immigration lawyers, they can take you through the different Work Permits that are available to you and help you legitimise your position in the UK.

    As an employer of overseas talent, there are certain sponsorship duties which you must fill.
    Firstly, if you do not already have one, you must obtain a Sponsor Licence before employing any non-EEA workers on Skilled Worker Visa or Tier 5 Visa.

    Once you have obtained such a licence, you must then issue a Certificate of Sponsorship to every prospective Tier 2 and Tier 5 migrant worker. This will enable them to apply for a work permit or visa, or extend their current stay in the UK.

    You must also ensure that you update your Sponsorship Management System (SMS) to keep relevant records and reports in relation to your workers. This includes ensuring they meet their visa regulations and reporting any breaches that may arise to the Home Office.

    Our immigration lawyers can assist you with any issues you may have when looking to employ and sponsor migrant workers. Our services include assisting you to apply for a Sponsor Licence and performing compliance checks. With this, we will make sure that your employment methods are functioning legally, and resolve any instances where they are not. We also offer appeal services if you have received a discipline, such as a Civil Penalty, from the Home Office.

    If you are employing migrant workers illegally in the UK, you may receive a fine and a warning from the Home Office called a Civil Penalty.

    Receiving a Civil Penalty can be detrimental to employers, as it may result in high costs, can negatively affect a company’s reputation and even cause a company or business to be closed down.

    If you have received a fine for employing workers illegally you will be given 28 days in which to proceed with one the three of the following options:

    1. You can choose to object to the penalty;
    2. You can directly request that a payment instalment plan is set up by the Home Office; or
    3. You can pay the penalty in full.

    The Home Office’s 28-day deadline is very strict and they offer no option for an extension of this period.

    If you have received a Civil Penalty for employing illegal workers, it is highly advisable that you seek the help of an immigration lawyer, who can offer urgent assistance with our appeal package.

    The lawyers at IAS have dealt with many cases in which migrant workers and UK employers have required advice about the legality of their actions.
    Our services are strictly confidential; we are equipped to offer you the support, guidance and advice you need.

    If you are a UK employer we will:

    • help you obtain your Sponsorship Licence so you can legally employ foreign workers;
    • perform an Immigration Audit to find and fix any issues with your current employment methods;
    • ensure your business’ HR methods are practising the law;
    • if you have received a penalty from the Home Office, find the best way to resolve or appeal the charge;
    • act as your legal representation if you choose to appeal;
    • prepare you for any visits from the Home Office;
    • liaise with the Home Office to discuss and resolve issues.

    If you are an employee we will:

    Get in touch with us on 0333 363 8577 free or fill out our online enquiry form to discuss any concerns you may have about working illegally in the UK.

    I spoke with Saima Jabeen about the areas where I needed assistance. She was very helpful and provided me with clear and useful information. I was satisfied with the support and guidance she provided.
    Very positive professional experience. My immigration advisor Mariam Adebayo helped my wife successfully obtain her Spouse visa extension. At the very start we had a face to face meeting at their Oldham office to discuss our needs, explain the process and what evidence we would need. We later received a written confirmation of advice laying out everything from timeframes, fees and documentation needed. Through out we had video calls and regular emails for updates and when our input was needed, Mariam even uploaded all of the extensive evidence as part of the application process which I was very happy with as I know from my own experience this can take a while. I would definitely use IAS again, don't be fooled in to opting for cheaper options, I came to IAS after a poor experience with a different company and so came back as I'd had a good experience with IAS way back in the 90's so know that they have been around for a years. Thank you IAS Oldham and Mariam Adebayo.

    I would like to express my heartfelt gratitude to Abdul Mutee for everything he has done throughout my visa process. The past year was incredibly stressful, especially after facing two Canada visa refusals. During this difficult time, Abdul Mutee did not simply provide guidance; he actively worked on my case and supported me every step of the way when I felt overwhelmed and uncertain about my future. Thanks to his dedication, hard work, and continuous support, my UK visa has now been approved. This approval allows me to continue my education and pursue my dream of becoming a dentist. I truly believe that this achievement would not have been possible without his assistance and commitment. Abdul Mutee played a significant role in making this outcome possible, and I am deeply thankful for the relief, hope, and opportunity he has given me. His efforts have made a lasting impact on my life, and I will always be grateful for everything he has done. I will never forget the support, encouragement, and professionalism he showed throughout this journey. Abdul Mutee's help has made a real difference in my future, and I sincerely appreciate all of his hard work and dedication.

    I used IAS for my first visa and I must say it wasn't a pleasant experience. We didn't receive all the information, we would find out about things along the way and it made it all very stressful even though the application was successful. We were a bit reluctant to do it again for the renewal but went for it anyway due to lack of time. Anne Liu was out caseworker and she was terrific! Super on top of the case! She would review the docs very quickly after we submitted it and would immediately tell us what would be missing. She made herself available when we needed her all the way up to the appointment. Definitely made the experience more stress free!

    Anne has been nothing short of exceptional throughout mine and my husbands immigration query. From the very start, she was informative, diligent, understanding, compassionate and helpful. Any immigration matter is delicate and stressful for those involved and Anne met us with patience and kindness throughout, keeping us well informed and calm when everything felt tricky. We honestly couldn’t have asked for a better advisor and we are so grateful for everything that she did for us to get my husbands spousal visa approved. Her dedication and commitment proved enormously valuable and I will be welcoming my husband home tomorrow because of her. Without a doubt we will use her again in 2029 when required and we cannot recommend her enough for anyone going through a similar matter. Thank you Anne, from the bottom of our hearts, we will always appreciate you and remember your engagement fondly.

    Everybody at IAS has been professional and helpful. In particular my case worker, Elena Ampova simply could not have been more patient, friendly and approachable and knowledgeable. Nina and I found it difficult to supply information in the file formats required and Elena spent hours helping us. And the end result has been that my fiancée, Nina's visa application has been approved. Perfect service and a perfect result.

    Dina's explanations were clear and she took time to make sure we understood. The only small worry we now have is that there may be hidden fees which were not specified. However, I'm just checking that through an email.

    I am extremely grateful for the excellent support and professional service I received from Immigration Advice Service, especially from my caseworker, Lauren Blommel. Lauren supported me throughout my asylum case and kept me informed and reassured during what was a very difficult and stressful process. Thanks to her professionalism, dedication, patience, and hard work, my case was handled with great care and I successfully received my refugee status. I truly appreciate everything Lauren has done for me and all the support she provided from beginning to end. I highly recommend Immigration Advice Service to anyone who needs immigration support.

    I cannot recommend Mariam Adebayo at IAS highly enough. She supported me thoroughly from A–Z throughout my UK Global Talent Visa journey, ultimately helping me successfully obtain my visa through the Exceptional Talent route. From the very beginning, Mariam was incredibly professional, knowledgeable, patient, and attentive. She guided me through every stage of the process with clarity and reassurance, always making sure that my application was as strong and comprehensive as possible. What stood out most was how consistently she went above and beyond her dedication, responsiveness, and genuine commitment to achieving the best possible outcome for me were evident throughout the entire journey. Thanks to Mariam’s exceptional support and hard work, I now have the incredible opportunity to continue developing and practicing my talent in the UK. This is a truly significant milestone in my professional and creative journey, and I am extremely grateful for the role she played in making it possible. Mariam is an outstanding caseworker and a true asset to IAS. I wholeheartedly recommend her to anyone seeking immigration support, particularly those applying through the UK Global Talent route. Thank you, Mariam, for your dedication, guidance, and for helping turn this opportunity into a reality.

    My case worker Mariam Adebayo guided my fiancee, a Belarusian national and me on what documentation and translations were required and checked through everything at every stage. She then made the application on our behalf for a fiancee visa. The application was 100% successful with no other documentation required or any queries raised by UKVI. Mariam further assisted in getting our spouse visa after our marriage in May 2026. Again 100% successful. Mariam has been extremely thorough in every part of our fiancee and spouse visa. Everything went through without a hitch! I have no hesitation in recommending her. Peter and Teresa Welch.
