Regulatory Status of Simpson Millar Solicitors

The regulator for Simpson Millar Solicitors is the Solicitors Regulation Authority.

The Immigration Advice Authority replaced the Office of the Immigration Services Commissioner as the statutory regulator for non-solicitor immigration advisers. The IAA continues to maintain a public adviser finder, currently signposted from gov.uk/find-an-immigration-adviser, where any prospective client can confirm the level and categories of authorisation for a registered adviser. References to OISC authorisation on older marketing materials should be read as referring to the same statutory regime, now operating under the IAA name.

For complaints and conduct concerns, the route depends on the regulator. SRA-regulated firms handle complaints internally first, then through the Legal Ombudsman for service complaints and the SRA for conduct issues. IAA-registered advisers handle complaints internally first, then through the IAA complaints scheme. Both routes are described in detail by the regulators and on gov.uk. The published outcomes give a sense of how each regulator approaches its caseload.

Fee Transparency

SRA-regulated firms are required by the SRA Transparency Rules to publish indicative pricing for immigration services on their website. The published rates typically distinguish between fixed-fee work, hourly billing for complex casework, and disbursements such as Home Office application fees and the Immigration Health Surcharge. Simpson Millar Solicitors operates under the regulatory framework described above and the firm's own website should be consulted for the most current published pricing.

Before instructing any UK immigration firm, the regulator-mandated client-care letter is the contractual baseline. It must set out the scope of work, the named caseworker, the supervision arrangements where relevant, the basis of charging including hourly rates or fixed fees, an estimate of total cost and a list of disbursements. A firm that cannot produce a written client-care letter and fee quote in a reasonable time is unlikely to handle the work transparently later.

Home Office application fees are paid directly to UK Visas and Immigration and are listed on gov.uk. They are separate from professional fees and from the Immigration Health Surcharge. A clear quote breaks down each component (professional fees, VAT, disbursements, and Home Office fees and charges) so that the client can see what is owed to whom and when.

What Clients Say

Independent client feedback on UK immigration firms is collected by Trustpilot, Google Reviews, ReviewSolicitors and similar aggregators. For Simpson Millar Solicitors a current Trustpilot listing is published at www.trustpilot.com/review/simpsonmillar.co.uk. The live TrustScore, review volume and percentage breakdown can be read directly on that page. The Trustpilot interstitial security check made the TrustScore unavailable to automated retrieval on 25 May 2026, so the current numbers should be read live rather than quoted at a fixed point.

Reviews about service speed, communication and clarity of advice tend to be reliable signals. Reviews about case outcomes are less reliable in isolation because outcomes depend on the underlying facts and the strength of the legal merits. A firm cannot guarantee outcomes, and a reviewer's disappointment in a refused application may say more about the case than about the firm. The volume of reviews and the consistency of themes over time are more informative than any single rating.

Cross-check independent reviews against the regulator's own published record. A firm with a clean regulator record and a consistent body of positive independent feedback over several years is a stronger prospect than a firm with high review scores but a record of upheld complaints. The published outcomes of regulatory action by the SRA, the Legal Ombudsman and the IAA complaints scheme are the most reliable indicators of how seriously a firm takes service quality.

Immigration Services Offered

The immigration practice areas listed on the firm's own website include personal injury, medical negligence, military claims, abuse claims, childcare and education law and related services. The firm's main About Us page accessed for this article does not list immigration as a current core practice area, and clients seeking immigration support should confirm directly with the firm whether immigration cases are currently being accepted. Each category requires the relevant authorisation, and for SRA-regulated firms the relevant practice rights are inherent in solicitor authorisation. For IAA-registered advisers the level (1, 2 or 3) and category (immigration, asylum or protection) determine what casework can lawfully be undertaken.

Simpson Millar Solicitors operates within the regulatory framework described above and confirms its practice areas through its own marketing material. Any prospective client should confirm at the initial consultation that the case falls squarely within the firm's current specialism and that the named caseworker has appropriate experience in the relevant visa or appeal category.

the Law Society Lexcel award for excellence in practice management, the Investors in People accreditation, and signatory status under the Armed Forces Covenant is what the firm's public-facing material currently states. The Lexcel mark is an external practice management standard granted by the Law Society. The Legal Aid Agency contract is granted following a tendering process and indicates that the firm has met specified quality standards in the relevant categories. These are layered on top of baseline regulatory authorisation, not substitutes for it.

How to Make a Complaint About Simpson Millar Solicitors

For SRA-regulated firms, complaints follow the firm's internal procedure first. If unresolved, service complaints go to the Legal Ombudsman at legalombudsman.org.uk and conduct complaints go to the Solicitors Regulation Authority at sra.org.uk. The Legal Ombudsman can require compensation up to its published limit; the SRA can impose disciplinary sanctions on individuals and firms, with the most serious outcomes recorded on the public register.

Acting as an unregulated immigration adviser for reward remains a criminal offence under section 91 of the Immigration and Asylum Act 1999, punishable on conviction by imprisonment for up to two years, an unlimited fine, or both. The IAA enforcement function investigates reports of unauthorised practice and works with the police and the Crown Prosecution Service where prosecution is appropriate.

When raising a complaint, keep contemporaneous records (emails, file notes, recordings if lawful), the client-care letter and the receipts for any payments made. The complaint to the firm should be in writing and should describe specifically what went wrong, what the firm should do to put it right, and within what timescale. The firm's published complaints procedure should give the named complaints handler and the expected response timetable.

Questions to Ask Before Instructing Simpson Millar Solicitors

Confirm the named caseworker who will handle the matter, the name of the supervising solicitor or senior adviser, the relevant authorisation under the SRA or the IAA, and the level of experience in the specific visa or appeal category. The combination of named caseworker and named supervisor is a reasonable expectation and supports clear accountability.

Ask for the firm's recent caseload in the specific category of advice required. A firm that handles dozens of spouse visa refusals each year offers experience that a firm doing one or two cannot. Many firms will share indicative figures on request, and the answer is itself informative whether or not specific numbers are produced.

Request a written fee quote that separates professional fees, VAT, disbursements and Home Office application fees. Ask how the firm bills for unexpected developments such as a Home Office request for further information or a refusal triggering an appeal. A clear answer at the outset supports a transparent working relationship throughout the matter.

Confirm how the firm handles language interpretation if needed, what its turnaround commitments are for Home Office correspondence, and how documents are shared securely. UK immigration casework runs on short statutory deadlines, and the firm's process for meeting them should be clear before work begins.
