Immigration Consultant UK 2026: Roles, Regulation, and How to Pick One

A UK immigration consultant is a regulated adviser who helps applicants prepare and submit visa, settlement, and citizenship applications. In 2026 the work is regulated by the Immigration Advice Authority (IAA), which replaced the Office of the Immigration Services Commissioner (OISC) in June 2024. Authorisation runs at three levels and dictates what each consultant can lawfully handle.

What an immigration consultant actually does in the UK

A UK immigration consultant advises individuals and businesses on the rules governing entry, stay, settlement, and citizenship under the Immigration Rules and related legislation. In practice the work falls into three buckets: initial advice and route eligibility analysis, preparation and submission of applications, and representation in correspondence with the Home Office or appeals before the First-tier Tribunal.

Initial advice covers reviewing the client's situation, identifying viable visa routes, mapping the documentary and English-language requirements, and producing a written eligibility opinion. For a Skilled Worker case, that means checking the role meets the Standard Occupational Classification code, the salary exceeds the going rate and the general threshold, and the sponsor is on the current register of licensed sponsors. For a family case, it means checking the minimum income requirement, the relationship evidence, and the accommodation requirement.

Application preparation is the most common paid task. The consultant gathers the supporting documents, drafts the personal statement and supporting cover letter, completes the online application form, and submits the bundle to the Home Office. For inside-UK applications, the consultant typically attends or supports the UKVCAS biometric appointment. For outside-UK applications, the bundle is uploaded to the VFS Global or TLScontact portal.

Representation work goes further. A consultant authorised at the right level can correspond with UKVI casework teams on behalf of the client, respond to requests for further information, draft administrative review requests, and (at Level 3) represent at the First-tier Tribunal (Immigration and Asylum Chamber). Solicitors can additionally conduct judicial review proceedings in the High Court and instruct counsel for higher tribunals.

The legal framework: IAA regulation explained

Paid immigration advice in the UK is regulated under Part V of the Immigration and Asylum Act 1999. Until June 2024 the regulator was the Office of the Immigration Services Commissioner (OISC), an independent non-departmental public body. From June 2024 the regulator was renamed the Immigration Advice Authority (IAA), with broader enforcement powers and an updated Code of Standards. Both names still appear in older marketing material; the underlying register and authorisation framework continued without interruption.

The Act makes it a criminal offence to provide immigration advice or services in the UK without being either authorised by the IAA, regulated by a designated qualifying regulator (which includes the SRA for solicitors, the Bar Standards Board for barristers, and CILEX Regulation for legal executives), or exempted by ministerial order. Penalties include fines, imprisonment, and disqualification orders preventing the offender from working in the sector.

The IAA publishes and maintains a Code of Standards that authorised advisers must follow. It covers client care, fee transparency, file management, professional indemnity insurance, complaints handling, and conduct. Authorised advisers undergo periodic IAA audits and continuing professional development requirements. The Code is published on the GOV.UK IAA pages and is the standard against which complaints are assessed.

The IAA does not regulate solicitors directly, because they are regulated by the SRA, but the practical effect is the same: a solicitor's firm offering immigration services must have a current SRA practising certificate, professional indemnity insurance at SRA-required levels, and a complaints process meeting SRA Standards. The Legal Ombudsman handles consumer complaints about solicitors that the firm has not resolved.

Consultant vs adviser vs solicitor: who can do what

The labels "consultant" and "adviser" are not protected terms. Either word can be used by any IAA-authorised individual or firm. What matters is the regulatory body, the authorisation level, and the named individual handling the file. An IAA Level 1 "consultant" and an IAA Level 1 "adviser" are doing identical regulated work.

A solicitor is a different category. To use the title "solicitor" in connection with legal work in England and Wales, the individual must hold a current practising certificate from the SRA. Solicitors operate inside law firms regulated by the SRA, which means they carry the full SRA regulatory overhead including the Solicitors' Indemnity Fund coverage tail and the Legal Ombudsman complaints route. A solicitor can do everything an IAA Level 3 adviser can do, plus litigation in the higher courts and judicial review.

Barristers, regulated by the Bar Standards Board, are usually instructed via a solicitor (the traditional route) although direct access is permitted for some immigration work. Barristers specialise in advocacy and complex written advice, typically becoming involved in tribunal appeals or judicial review where their courtroom advocacy or specialist drafting is needed.

For the average applicant on a routine work, family, or visitor route, the practical choice is between an IAA-authorised consultant or adviser at Level 1 or Level 2, and an SRA-regulated immigration solicitor. Both are properly regulated, both must hold indemnity cover, and both can be reported to their regulator if service falls short. The choice usually comes down to price, location, and case complexity.

Levels 1, 2, and 3 authorisation explained

The IAA grants authorisation at three levels, each defining the scope of work the consultant can lawfully provide. The three levels apply across the main work categories: Immigration, Asylum and Protection, and (in some firms) Education or Sponsor Licence compliance work. Consultants are authorised at a specific level in a specific category, and the public register shows both.

Level 1 covers initial advice and applications. A Level 1 consultant can advise on visa, settlement, and citizenship routes, prepare and submit applications, and correspond with the Home Office on straightforward matters. Level 1 does not authorise the consultant to handle appeals, judicial review, or applications involving complex case law or evidential challenges. Most routine Skilled Worker, family, visitor, and ILR work is delivered at Level 1.

Level 2 covers more complex casework. A Level 2 consultant can prepare and lodge administrative review requests and First-tier Tribunal appeals (drafting and filing), respond to substantive requests for further information, and handle applications where the legal issues are not straightforward but no oral advocacy is required. Level 2 is the typical authorisation for refusal management and complex family or human rights cases at the application stage.

Level 3 covers representation at the First-tier Tribunal (Immigration and Asylum Chamber), including oral advocacy at appeal hearings, drafting witness statements and skeleton arguments, and instructing experts. Level 3 consultants compete with solicitors for tribunal work and often work alongside counsel. Beyond Level 3, judicial review and Upper Tribunal advocacy generally require an SRA-regulated solicitor or a barrister.

How to verify a consultant is regulated

The Immigration Advice Authority publishes a free public register at GOV.UK: find an immigration adviser. The register is searchable by postcode, by adviser name, and by firm name. Each entry shows the firm name, the authorised individuals within the firm, the categories of immigration work the firm is authorised for, the authorisation level in each category, and any restrictions on the authorisation.

The simplest verification process is to take the firm name and the named individual quoted in the client care letter and search both on the register. If either does not appear, or appears at a lower authorisation level than the work being quoted for, that is a hard stop. Authorisation is granted to specific individuals, not generically to a firm, so an authorised firm can still employ unauthorised junior staff who are not allowed to give regulated advice.

For solicitors, the verification route is the Solicitors Regulation Authority's public records. The Law Society's Find a Solicitor service, which draws on the SRA records, allows verification of a named solicitor's practising certificate, the firm they are attached to, and the area of practice. A solicitor offering immigration work should appear in the immigration category on Find a Solicitor and on the firm's own SRA-regulated profile.

For barristers, the Bar Standards Board maintains a barristers' register on its website. For CILEX-regulated legal executives, CILEX Regulation publishes a register. In each case the principle is the same: never pay an immigration consultant without first verifying their authorisation on the official register that corresponds to the regulator they cite.

Risks of using an unregulated consultant

An unregulated consultant operates outside the statutory framework. There is no professional indemnity insurance to claim against if the application goes wrong, no Code of Standards to enforce, no regulator to investigate complaints, and no complaint route via the Legal Ombudsman. If the consultant disappears mid-case, the client has only the civil courts as a remedy, and only if the consultant can be traced and is solvent.

There is also a practical risk to the application itself. An unregulated adviser may not understand the Immigration Rules at the level required to produce a clean application. Procedural errors, missing mandatory evidence, or misstatement of facts on the application form can result in refusal on grounds of inadequate evidence or, in serious cases, refusal under the general grounds for deception. A deception finding can carry a re-entry ban of up to ten years and is extremely difficult to overturn.

Unregulated consultants are sometimes presented as "immigration agents" or "visa processing services" outside the IAA framework. Where the operation is purely administrative (filling in fields on a form at the client's direction, without giving advice on the underlying rules) it may sit outside the regulated activity. Where any element of legal advice is given for payment, the activity falls within the statutory definition and triggers the criminal offence under section 84 of the Immigration and Asylum Act 1999.

Reports of unregulated activity should go to the IAA via the complaints route at GOV.UK: complain about an immigration adviser. The IAA has enforcement powers and works with the police where serious or organised unregulated practice is uncovered.

Choosing a consultant for your case type

Match the consultant's authorisation to the work. A straightforward Skilled Worker visa application for a clean candidate with a clean immigration history is well handled at IAA Level 1. The fee is lower and the service is appropriate. The same case after a prior refusal, with a deception allegation on file, or with a missing absence record over a long residence period, needs Level 2 at minimum and probably Level 3 or a solicitor.

Family route work spans a wide complexity range. A first spouse visa application from a couple with simple finances and a clean record can be handled at Level 1. A spouse visa under the exceptions to the minimum income requirement, or a parent route case with complex contact arrangements, sits at Level 2 or above. A human rights appeal against refusal of family leave is Level 3 or solicitor territory.

Sponsor licence work and right-to-work compliance for employers is its own category. Some IAA firms specialise in business immigration and offer Level 1 or Level 2 authorisation in the Immigration category combined with sponsor management system support. SRA-regulated firms with employment and immigration teams are an alternative, often appropriate for larger employers needing combined HR and immigration advice.

For citizenship work, IAA Level 1 is usually sufficient for clean naturalisation applications. Cases with good-character issues, deception allegations, or refused naturalisation applications need Level 2 or a solicitor. Once again the principle is consistent: choose the lowest authorisation level that fully covers the case, because higher levels usually mean higher fees, and verify the named individual on the register before paying.

Frequently asked questions

Is an immigration consultant the same as an immigration adviser?

In practice yes. Neither title is legally protected. What matters is the regulatory body and the authorisation level. An IAA-authorised individual using either label is doing the same regulated work. A person calling themselves a consultant who is not on the IAA register, the SRA's solicitor records, or another designated regulator's register is operating outside the legal framework for paid immigration advice.

What did OISC become?

The Office of the Immigration Services Commissioner (OISC) was renamed the Immigration Advice Authority (IAA) in June 2024. The statutory functions, the register of authorised advisers, and the Code of Standards continued under the new name. Older firm marketing may still refer to OISC; the relevant register is now the IAA register, accessible via the standard GOV.UK adviser finder.

Do I have to use a regulated immigration consultant?

No. Self-representation is permitted at every stage from initial application to tribunal appeal. Many applicants apply successfully without paid help by following the GOV.UK guidance closely. The point of regulation is that if you do pay for advice, the person taking your money must be authorised. Free advice from registered charities and law centres also remains widely available for those who cannot pay.

How do I check if my immigration consultant is registered with the IAA?

Use the public register at GOV.UK: find an immigration adviser. Search for the firm name and the named individual quoted on your client care letter. Confirm that the individual appears at the authorisation level appropriate for your case, in the correct category (Immigration, or Asylum and Protection). Authorisation is granted to specific individuals, not generically to firms.

Can an IAA Level 1 consultant handle my appeal?

No. Level 1 covers initial advice and applications only. Administrative review and First-tier Tribunal appeal work requires Level 2 (for filing and casework) or Level 3 (for representation at the hearing). A Level 1 consultant taking on appeal work is acting outside their authorisation and the work would not be lawfully delivered.

Are charity-based immigration advisers regulated too?

Yes. Charity, law centre, and not-for-profit immigration advisers must hold IAA authorisation at the level appropriate to the work they provide, even when the advice is free. Charity status does not exempt the organisation from the regulatory framework. The IAA register lists not-for-profit advisers alongside commercial firms.

What happens if I use an unregulated immigration consultant by mistake?

The application itself is not automatically invalid, but the risks are substantial: no indemnity cover if the work is negligent, no regulator complaint route, and potential criminal exposure for the unregulated consultant. If you discover the consultant is unregulated, stop further payments, gather your file copies, report the activity to the IAA, and consult a properly authorised adviser or solicitor to take over the case.

How we verified this

The regulatory framework set out in this guide was cross-referenced against the Immigration and Asylum Act 1999, the IAA's published Code of Standards on the GOV.UK Immigration Advice Authority pages, and the GOV.UK find an immigration adviser register. The June 2024 rename from OISC to IAA was confirmed against the Home Office's published machinery-of-government changes for that period. The role descriptions for solicitors, barristers, and CILEX-regulated executives were checked against the SRA, Bar Standards Board, and CILEX Regulation public pages.

No specific firm names, individual advisers, FCA or FRN numbers, or telephone numbers are quoted in this guide. Where a current figure or contact detail could not be confirmed, the text directs readers to verify the live position on GOV.UK or the relevant regulator's website. The guide reflects the regulatory position as at May 2026.
