1. White Horse Notary Public London
Website: https://www.whitehorsenotarypublic.com/
Address: 96 White Horse Lane
Contact: 020 3817 7502
Hours: Monday-Friday, 9:30 AM-5:30 PM
If you want a more personal approach, White Horse Notary Public London handles everything from Apostille legalisation to mobile visits.
Muhammad Karim personally oversees the practice, which means you always deal directly with a qualified solicitor who knows the ropes. This setup is especially handy for expats who need quick turnarounds without the bureaucratic shuffle.
When we gave his office a ring about authenticating some personal records, he clearly explained how they handle digital certifications using recognised electronic signatures.
You can even arrange same-day or weekend appointments if you ask in advance.
The catch is that relying on a single practitioner can lead to scheduling conflicts during busy periods.
Even so, if you prefer dealing with one experienced professional rather than a revolving door of staff, this practice is a solid choice.

2. Notary.co.uk – Notary Public London
Website: https://notary.co.uk/
Address: 6 Lower Grosvenor Place
Contact: +44 (0)20 7630 1777 / [email protected]
Hours: Monday-Friday, 9:00 AM-6:00 PM
Large stacks of corporate contracts usually require a firm with serious manpower.
Fortunately, Notary.co.uk, Notary Public London, has a large team of qualified professionals based in Victoria. This makes them well suited for extensive international paperwork.
The team handles eNotarisation and consular legalisation, while also offering document translation in one place. This setup can save businesses time when several documents need attention at once.
What really stands out is their speed and capacity for urgent business needs. A corporate professional handling an overseas merger can book next-day Apostille services or request an urgent turnaround when time is tight.
Plus, they offer a mobile service throughout the week, so a notary can come directly to your boardroom.
However, appointments outside standard office hours come with extra fees, and weekend visits are available by request only.

3. Notary Public Lincoln’s Inn Fields Holborn – S Thomas Notary Public & Legalisation Services
Website: https://www.sthomasnotarypublic.com/
Address: 29 Lincoln’s Inn Fields, Holborn
Contact: 020 7269 9590
Hours: Monday-Friday, 8:00 AM-6:00 PM
A demanding job makes it nearly impossible to sneak out for legal appointments during the day. Gladly, Notary Public Lincoln’s Inn Fields Holborn accommodates out-of-hours meetings without charging an extra premium.
They handle everything from individual travel permissions to complex corporate patent transfers.
A colleague of mine needed last-minute corporate minutes certified here, and they happily squeezed her in late in the evening for the standard rate.
They even cover a wide service area outside central London, including Camberley and Slough.
The downside is that they rely on external agents for Apostille work, which can sometimes slow down the final legalisation step.
To add, they charge a £40 fee to retrieve stored files, but they remain an excellent pick for flexible scheduling.
Customer Reviews
Thank you so much for your services
This is my second time with Sajo and absolutely nothing as changed. He’s really helpful, kind and understanding. I had some documents notarised only for the needed place to require another notarisation. I was charge normally but honestly couldn’t afford it so I didn’t do it. But he rang me back the next day to say he could understand my situation and offered to notarise for me at a very huge discount.
Thank you so much for your services.

4. Castelo Notaries
Website: https://www.castelonotaries.com/
Address: 83 Victoria Street
Contact: 020 3441 5095
Hours: Monday-Friday, 9:00 AM-8:00 PM; Saturday, 9:00 AM-6:00 PM
Foreign documents often require several agencies for translation and verification. Castelo Notaries makes the process simpler with a multilingual team that handles both services efficiently.
They work with individuals and businesses, and they can provide same-day solutions for urgent deadlines. This multicultural expertise is especially useful for expats dealing with complex inheritance or property matters back home.
Plus, you can arrange certified translations over the phone, and the team can send a mobile notary to your chosen location.
Their extended evening and Saturday hours also make appointments easier to fit around a busy week.
However, individual clients may have to compete with larger businesses for peak booking slots.
