If you cannot find the right service type in the list of the agency’s offers — no worries. Many companies provide clients with the opportunity to develop a custom UX solution. Even if your request does not fall into any of the service categories, do not hesitate to contact the UX UI design agency that catches your attention. They will likely offer a personalized problem-solving strategy for your project.
User experience research
A UX agency in London can conduct UX research for you to define and study your user persona, show user flows, map the user journey, and validate your business idea. At Limeup, we use effective UX research methods (user interviews and testing) and conduct competitor research data analysis to help you discover and solve user pain points.

UX/UI audit and optimisation
In 2-4 weeks, the UX design team conducts a deep audit of your digital solution or digital product, to spot, document, and solve usability issues that negatively impact user engagement. After the issues are fixed and the product is optimized, you can improve your digital product’s performance and key business metrics.
A/B testing and analytics
A/B testing and analytics services are helpful when you cannot choose between several UX design options or ideas and need data-driven evidence of what works better for your audience.
A/B testing involves the creation of two variants of a page. Both are presented to the target audience. Hereafter, designers collect statistical data on the performance of each variant and the interaction metrics. After comparing the two options, the team decides on the best variant that appeals most to the users.

Accessibility and inclusivity
A trusted user experience design agency can help you make your solution accessible and inclusive. Accessibility and inclusivity in the digital world of design mean providing anyone with equal access to sources and services. In design, it is implemented in convenient and customizable interfaces that can be adjusted to the particular user’s needs.
UX consulting
UX consultancy is a good option for businesses that plan to hire a UX designer but do not know where to start. During the consultation, your business design partner will dive deeply into your project idea, outline the challenges to be solved with design, and develop an effective project strategy to help you reach your goals.
Ongoing UX maintenance and support
After launching the product, you can refer to support and maintenance services to ensure your solution works smoothly. At this stage, your team will deeply analyze the user interaction with your product to promptly detect any pain points and fix all the issues.
Ongoing support and maintenance are also helpful if you plan to regularly improve your product by renovating the visual design, adding new elements or components, and preparing your digital solution to scale.
4 benefits of hiring a UX design agency
We highlighted a few benefits when partnering with the right UX design agency.
1. Better user experience
Leading UX agencies will carefully listen to your goals and project expectations and plan how to bring your idea to life. They will do their best to help you align your business tasks with user expectations to provide a high-quality user experience.
According to a study by Oracle, more than 85% of clients are eager to pay more for a good user experience. For businesses, investing in UX is a way to make clients happy and get fruitful results at the same time.
An example of how dedicated teamwork can drive seamless user experience is i88 — the design case recently delivered by the Limeup team. i88 is a complex online trading platform we designed from scratch.
The project’s task was to create a clean visual design and add familiar UX elements while highlighting the uniqueness of the business. As a result, our UX design firm got 100+ final screens for the web, 70+ screens for the mobile app, 50+ screens for CRM, plus an adaptive design version that will work smoothly on any device.

2. Improved conversion rates
Top UX design companies help clients create a seamless user experience and increase conversion rates. A bright example of a good UX in action is seen in the study by Adam Silver. The case took place when Silver was working at Just Eat. At that time, the company used a single-page checkout with many elements, panels, and steps on one screen. Customers struggled when making orders as they needed to scroll up and down to find some information.
Together with the team, Silver decided to redesign the page by breaking it down into several screens. Each screen was dedicated to a separate panel or step. As a result of this small change, the company got extra 2 million orders a year! Their case demonstrates how a convenient interface can improve performance metrics and bring more revenue.
3. Enhanced brand image
Nearly 20 years ago, key business players in the market did not care about their brand image since customers had few options to choose from. Today, identity differentiates a business and makes clients trust a company. User experience has a big influence on the perception of a brand.
In the study by Lucidpress, more than 50% of constituents agreed on the importance of great visual design and consistent branding for customers across all channels. A consistent UX strategy can help you build a distinguishable brand identity.

4. Increased ROI
A significant effect of user experience on business ROI was explored in the study by Forrester. The study reported that, on average, every dollar invested in user experience brings 100 in return. This marks an ROI of more than 9,900%.
By investing in user experience design, you make a greater impact on the user right from the start and save money that could be wasted on fixing UX issues.

How to choose a UX agency
As stated in Amazon’s Guide to the ROI of UX, businesses that invest in UX get a higher client retention rate, lower customer acquisition costs, and an increased market share.
Choosing among the Top UX agencies gives you a chance to build a data-driven and user-centric solution that will positively impact your performance metrics.
For each UX agency, answer the following questions:
- How much experience does an agency have in my niche?
- Have they built projects that have something in common with mine?
- What is their tech stack?
- Do they have enough employees to cover my project needs?
- What do other clients say about the agency?
- What is my overall impression of the agency? Am I inspired by their aesthetics and the solution they create?
After answering these questions, your list will likely narrow to a few candidates. Hereafter, check if these candidates can meet your project expectations, such as budget, timeline, cooperation model, scope of work, business goals, creative requirements, etc.
Now, you are ready to get in touch with the UX agencies of your choice and book a call. During this stage, trust your gut but confirm your choice with clear arguments and facts.
Apart from hard skills, evaluate the team’s interest in your goals and their readiness to solve your challenges with creative visual design ideas. By doing so, you will likely find the best match for your design project.
