A visa deadline or an unexpected Home Office letter has a way of turning an ordinary week upside down, and the right adviser makes a real difference to the outcome. We compared every immigration firm in London with a genuine Google track record, weighed how many clients rate them and how consistently, and narrowed the field to five you can approach with confidence. Here is who earns the shortlist, and how we ranked them.

Short answer: The most-reviewed immigration firm in London is A Y & J Solicitors, with a 4.9 rating across more than 1,400 Google reviews, followed by Reiss Edwards (4.9, 1,325 reviews) and Cranbrook Legal (4.9, 806 reviews). All three are established central-London firms handling visas, Indefinite Leave to Remain and appeals. Immigration help is usually priced per application as a fixed fee, separate from the Home Office and health-surcharge charges, several firms here offer a free first call and instalment plans, so get a written quote before you commit.

A Y & J Solicitors is a Holborn-based UK immigration law firm that, by its own account, has helped more than 5,000 clients with visa and settlement applications. The team covers the full immigration range, visit and family visas, spouse and partner routes, Indefinite Leave to Remain, and the BN(O) settlement route for Hong Kong families. Based on High Holborn, it works by appointment during the week, and clients single out named case handlers who guide them through ILR and visit-visa work. It positions itself as an award-winning practice built around visa success.

  • Replies often within 24 hours, with regular updates at each stage
  • Detail-focused review of financial documents and supporting evidence

Our take: The most-reviewed immigration firm on this list and tied for the top 4.9 rating, which makes it our safe default for visa and settlement work. Its depth on tougher routes such as BN(O) settlement is a real plus for complicated cases.

Our take: OTS actually carries slightly more reviews than Westkin above it, but we rank it fifth because its 4.7 average sits just under the 4.9 cluster, excellent volume, a marginally lower score. For transparent flat-rate fees and quick ILR work, it is still a strong call.

Watch: 5 Best Immigration Consultants in London (2026)

How we score

Every figure here comes from public Google data on the date shown, not from opinion or payment. Rating is each firm’s live Google star average. Review volume is how many clients have rated them, ranked against other London immigration firms. Confidence weighs the rating by that volume, so a 4.9 from over a thousand people counts for more than a 4.9 from a handful. Recency reflects how lately clients are still leaving reviews. No firm can pay to change these numbers.

What do immigration consultants charge in London? (2026)

Immigration fees in London swing widely with the type of application and how complicated the case is. A straightforward visit or spouse visa costs far less in professional fees than an appeal, a sponsor licence or a case with a refusal behind it. Most firms here quote a fixed fee per application, and several offer a free first call and instalment plans. Keep in mind that the firm’s fee is separate from the Home Office application charge and the Immigration Health Surcharge, which you pay on top. Always ask for a written, itemised quote and confirm exactly what is included before you instruct anyone.

Serving London and beyond

The firms above cluster in central London’s legal district, Holborn, Chancery Lane, Gray’s Inn, the City around Cannon Street, and Mayfair, but they act for clients across Greater London and the rest of the UK, and several offer phone and video consultations if you cannot travel. Searching for an immigration consultant near me? Each listing below shows a live phone number and directions so you can reach the closest office quickly.

What to ask before you instruct an immigration adviser

  • Are you regulated by the SRA as a solicitors’ firm, or by the OISC, and at what level?
  • Is your fee fixed per application or charged by the hour, and what does it include?
  • Are the Home Office fee and the Immigration Health Surcharge separate from your fee?
  • Who will actually handle my case day to day, and how quickly do you reply?
  • How much experience do you have with my specific route or type of case?
  • What happens, and what does it cost, if the application is refused and needs an appeal?

Frequently asked questions

How did you choose these immigration firms?

We started from London firms with a genuine public Google presence, then ranked them by rating, review volume, consistency and how recently clients are still reviewing. See How we score above for the detail.

Are these rankings paid?

No. Rankings come from the public Google data in each scorecard. A firm can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another firm’s score or position.

What is the difference between an immigration solicitor and an OISC adviser?

Solicitors are regulated by the SRA and can offer wider legal services; OISC-registered advisers are regulated specifically for immigration work, at set levels of case complexity. Both can lawfully advise on and run immigration applications, the right choice depends on your case. The firms on this list include both.

How much do immigration consultants in London charge?

It depends heavily on the application and its complexity, so we do not quote a single figure. Most firms here charge a fixed fee per case, separate from Home Office and health-surcharge costs, and several offer a free first call and instalments. Always get a written quote first.

Do these firms handle visa refusals and appeals?

Yes. Several, including Reiss Edwards, Cranbrook Legal and Westkin Associates, list appeals, administrative review and judicial review among their services. Confirm the fee and approach for your specific refusal when you call.

How often is this list updated?

The data carries a verified date, July 2026 on this page. We refresh the ratings and review counts periodically so the scorecards stay current.

The bottom line

For most people, A Y & J Solicitors is the safe default, the highest review volume on the list at a 4.9 rating, while Reiss Edwards and Cranbrook Legal match it on rating and suit cases that need family-law or business-immigration depth. Whoever you choose, confirm how they are regulated and get a fixed fee in writing before you instruct.
