Frequently asked questions

A request is any task you assign us—whether designing a logo, conducting UX research, implementing an AI chatbot, or making revisions to existing work. Each request enters your queue and is addressed according to your priorities by the appropriate specialist from your subscription package.

You’ll have a dedicated project manager as your main point of contact who coordinates your requests across our team. Depending on your subscription, you’ll work with senior designers, developers, motion graphics artists, UX researchers, CRO specialists, or AI engineers—all within the top 0.5% of talent in their fields.

Both plan types offer the same level of service and unlimited requests. Monthly plans offer maximum flexibility with no long-term commitment, while quarterly plans provide a 25% discount. Both can be canceled with no hidden fees—your subscription simply won’t renew for the following period.

Yes, we offer flexible hourly packages ranging from 1 to 16 hours per month for projects that don’t require unlimited service. These packages are perfect for maintenance, small updates, or occasional creative needs. Our hourly packages include:

  • 1-hour package ($187/month)

  • 4-hour package ($599/month)

  • 8-hour package ($1,199/month)

  • 16-hour package ($2,399/month)

All hourly packages provide access to the same senior talent as our unlimited subscriptions and can be used across design, UX optimization, or AI services depending on your specific needs. Quarterly commitments for hourly packages also receive a 25% discount.

We believe in complete flexibility with no hidden commitments. You can cancel your subscription at any time through your client dashboard or by contacting your dedicated project manager. There are no cancellation fees or penalties—your subscription simply won’t renew for the following billing period. For monthly plans, you’ll have access until the end of your current month. For quarterly plans, you’ll maintain access until the end of your paid quarter. All your assets, designs, and deliverables remain fully yours after cancellation, and we’re happy to provide any transition assistance you might need.

Our focus is on providing expertise and implementation rather than licensing third-party tools. As a general rule, if the software is paid and serves as an input to our service (such as A/B testing platforms, development API costs, or specialized AI services), clients are responsible for those licenses. We’re happy to recommend appropriate tools based on your needs and budget, and our team is experienced with most industry-standard platforms. For implementation services like setting up or configuring tools, that work is included in your subscription. We can also help you evaluate which tools would be most cost-effective for your specific objectives.

Yes, absolutely. While our service lists are comprehensive, we understand that digital needs often extend beyond standard categories. If your request relates to the expertise within your chosen package (design, UX optimization, or AI implementation), our senior specialists can likely accommodate it. For example, though we don’t specialize in Wix development, our design team can make updates using the Wix editor within the Grow package. Simply ask about your specific requirements, and we’ll transparently assess if we can deliver the high-quality results you expect. Our goal is to be flexible while maintaining our premium quality standards.

Yes, we provide comprehensive documentation and training for all implemented solutions, whether they’re websites, design systems, or AI applications. Our goal is to ensure your team can effectively utilize and manage the deliverables.

If you’d like to learn more, please book a consultation call. If you’re ready to start, select your preferred package (Grow, Optimize, or Innovate), complete the checkout process, and we’ll schedule a kick-off call to discuss your priorities and establish workflows immediately.

Ux Design Agency London

In the bustling metropolis of London, a city renowned for its innovation and creativity, the demand for superior UX design has never been higher. Companies, both large and small, are in a constant search for design solutions that not only meet their immediate needs but also position them advantageously in a hyper-competitive market. This is where the quest for a top-tier UX design agency London comes in. The landscape of UX design in London is vibrant and diverse, offering a plethora of options to those in need. Among these options, one service model has started to stand out significantly: the unlimited design service model provided by agencies such as Passionate Design Agency. This model is rapidly growing in popularity and is reshaping expectations around design services.

Traditionally, businesses looking to enhance their digital presence had two primary avenues: hiring in-house designers or outsourcing projects to fixed-quote agencies. While both methods have their advantages, they also come with limitations that can stifle creativity and efficiency. Hiring an in-house team guarantees constant availability and potentially a closer alignment with the company’s culture. However, it often comes with a hefty price tag due to salaries, benefits, and the resources needed to support a creative team. On the other hand, working with a typical fixed-quote agency can give access to a broader skill set but might lead to escalating costs and inflexibility due to the project’s scope creep.

Enter the unlimited design service model championed by Passionate Design Agency—a UX design agency London known for its innovative approach. This model effectively bridges the gap between the traditional in-house and agency setups, offering a solution that is both cost-effective and highly adaptable. The Passionate Design Agency provides unlimited premium design, video, and website development services for a flat monthly fee, a structure that is rapidly gaining favor among businesses in London and beyond.

At the heart of this model are the unlimited requests packages, tailored to meet various needs and budgets. For instance, the Sprint package, priced at $2999 every two weeks, allows for one concurrent request at a time, making it perfect for businesses with urgent, short-term projects. The Standard package, at $4999 per month, also permits one concurrent request and is suited for companies with ongoing design needs. Meanwhile, the Enterprise package, at a $9999 flat fee, allows for two concurrent requests, offering substantial capacity for larger organizations with complex and multi-faceted projects.

What sets this model apart, particularly for a UX design agency London seeking to make a significant impact, is the combination of flexibility, speed, and quality. Clients can expect to receive deliverables every 1-3 working days, a turnaround time that is unheard of with traditional fixed-quote agencies. Moreover, Passionate Design Agency employs the top 0.5% of talent across Europe, ensuring that each project not only meets but exceeds industry standards.

Passionate Design Agency’s unlimited design service model encompasses a wide range of services, including branding, UI/UX, graphic design, web design, WordPress, Webflow, and Shopify development, as well as video production and motion graphics. This comprehensive approach, combined with the model’s inherent flexibility, means that businesses can view Passionate Design Agency as their in-house design team, ready to tackle any project at a moment’s notice.

The cost-effectiveness of this model is particularly striking. For roughly half the price of what one might expect to pay for a fixed quote from a typical agency, clients of Passionate Design Agency receive premium services that rival, if not surpass, those offered by in-house teams and traditional agencies. This affordability does not come at the expense of quality or creativity. In fact, with access to an outstanding pool of designers and developers, businesses can expect innovative and bespoke solutions that drive value and enhance user experience.

Having designed and built a few hundred websites and executed hundreds more projects, Passionate Design Agency stands as a beacon of excellence in the UX design agency London scene. Its model is not just an alternative to traditional design service offerings; it’s a complete reimagining of what businesses can expect when they invest in design. The agility and adaptability provided by the unlimited design service model make it an unrivaled choice for companies aiming to thrive in today’s fast-paced digital environment.

In essence, the rise of unlimited design services, with Passionate Design Agency at the forefront, marks a pivotal shift in the UX design agency London landscape. It reflects a broader move towards flexibility, efficiency, and unbounded creativity in the business world. For those seeking to bolster their digital presence with cutting-edge design and development work, looking towards agencies offering this innovative model may just be the key to unlocking unparalleled success in the digital age.

We also provide unlimited premium graphic design, video, and website development services to businesses around the world including:
