What Are the Most Legitimate and Best Translation Agencies Today?

Approaching international and multilingual consumers in today’s globalized world is the bread and butter for large, worldwide companies, but also a growing number of SMEs from the United Kingdom. With developments in technology, widely accessible internet and the popularity of social media, businesses and organizations take full advantage of the relative ease with which they can approach wider audiences and explore new, overseas markets.

Nonetheless, although easier than ever before, approaching global markets and customers still requires business owners to carefully consider certain specific aspects of their internationalization, which can directly determine just how successful their expansion will actually be. One of the most important of such factors is the correct use of language.

In order to ensure that your company presents itself abroad in a professional, friendly and customer-oriented manner, it is essential that you approach your chosen market directly in its native language. To do so, a rapidly growing number of global brands, businesses and organizations decide to partner and work closely with professional language translation agencies.

Working with a specialist translation agency will help your business not only to accurately convert any marketing, legal or financial documents necessary in order to successfully approach an overseas market but in some cases can also help you in understanding cultural and socio-demographic aspects. These often also play a key part in determining how your company is perceived internationally.

Choosing a Translation Agency – What to Look Out For?

Despite now knowing the 5 best and most popular translation agencies in the United Kingdom, you still may not be fully certain what to look out for and which company will in fact be the right choice for your particular needs, and that’s understandable.

Larger translation agencies, such as Lionbridge or TransPerfect are a great choice for AI-based solutions. As they specialize in digital content creation, partnering with such a company may be the best choice if your company or organization requires a complex solution with an emphasis on AI. These, unfortunately, tend to be on the slightly expensive side and so may be better suited for large, international corporations.

On the other hand, agencies such as Translation Services 24 are able to provide professional language solutions across practically all corporate industries, documents or languages. Companies such as TS24 generally have a large network of translators and interpreters, allowing them to offer their services at reasonable prices, not only to business clients but also to individual customers.

Best External Online Resources for Finding a Translation Agency

The number of professional human translation service suppliers grows continuously, and so does the number of independent databases and websites which offer third-party reviews. Today, finding the best agency for your particular language requirements can be done fairly quickly online. Whether you’d like to explore more information about some of the providers we have described above, or perhaps you wish to find another specialist agency, fantastic independent resources are available.

One of the most popular websites, which allows you to search, compare and contact translation agencies is Clutch. This website lists all of the most popular and reliable providers in the United Kingdom and shows independent client reviews. Additionally, as the reviews are linked to the clients’ professional profiles, such as LinkedIn, you can rest assured that the testimonials are truthful and based on actual experience with the agency.

Other websites, such as the ATC UK (Association of Translation Companies) database, proz.com or GoodFirms also list several professional translation companies. In addition, Proz.com is also a directory for professional freelance linguists and you can search them based on a number of filters, such as their skills, availability experience or languages covered. This may be extremely helpful if you decide to work with freelance linguists, rather than a specialist agency.
