When it comes to architectural services, you may find yourself confused by the different titles and qualifications of those offering them.

A common question frequently asked is: what’s the difference between an architect and architectural designer?

Put simply, in the UK, an ‘architect’ is a registered professional trained to organise, design and manage the construction of buildings. On the other hand, ‘architectural designer’ is a broad, unregulated title for individuals who are not registered architects but provide architectural services.

In this guide, we explain the roles of the various individuals offering architectural services, helping you choose the right person for your project.

What is an Architect?

An architect is a creative professional who designs buildings and oversees their construction. Architects are the highest qualified design consultants in the construction industry.

In the UK, the title ‘architect’ is protected by law. To qualify, they must complete 7 years of training, including 5 years at university and 2 years in professional practice, and register with the Architect Registration Board (ARB). Architects must follow the ARB's Architects Code and hold Professional Indemnity Insurance (PII).

To check if someone is an architect, you can visit the ARB’s online register.

Many architects also join the Royal Institute of British Architects (RIBA), a voluntary membership that demonstrates further commitment to the profession.

What do Architects do?

Contrary to the misconception that architects only come up with creative ideas, their extensive training means they can manage all stages of a building project, such as:

  • Organising the project and setting out tasks needed to be completed the project successfully.
  • Designing all aspects of the building including the exterior envelope and interior spaces.
  • Advising on planning policy and securing planning permission.
  • Coordinating design work completed by others and integrating it into the design (eg structural and mechanical engineers).
  • Ensuring technical compliance with the building regulations and other bodies (eg party wall and utilities).
  • Advising on build costs and preparing pricing documents for builder estimates.
  • Organising and analysing tenders.
  • Preparing building contracts and overseeing the building work on site.

What are the main benefits of using an Architect?

Architects can provide an end-to-end service, maximising the potential of your project while managing time, cost, and quality. They integrate modern technologies and sustainable construction methods, coordinate the work of other consultants, ensuring everything works harmoniously together and is built to the correct standards.

What is an Architectural Designer?

An architectural designer is anyone offering architectural services who is not a registered architect. The title is unregulated, meaning anyone can use it, regardless of qualifications.

Most architectural designers have some level of training, but the quality of service can vary widely. Some may lack the expertise to guide a project through all phases or may not hold PII. Therefore, it’s essential to check their experience, view past projects, and verify they hold insurance before hiring one.

What is an Architectural Technologist?

An architectural technologist specialises in the science of building design. While their training isn’t as extensive as an architect’s, they can assist homeowners and developers with technical details and ensuring building regulations compliance.

The title ‘chartered architectural technologist’ is protected, and those holding it have completed a degree and become members of the Chartered Institute of Architectural Technologists (CIAT). Like architects, CIAT members must follow a code of conduct and hold PII.

What is an Architectural Technician?

An architectural technician works under the direction of an architect or chartered architectural technologist, assisting with drawings and technical documents. While similar to technologists, they typically have a narrower skill set.

What is an Interior Designer?

An interior designer focuses on creating aesthetically pleasing interior spaces. They work on aspects such as room layouts, furnishings, colours, and lighting to enhance a building's interior.

Interior designers do not typically handle structural aspects or provide guidance on planning applications and building regulations. They often collaborate with architects or builders and are not qualified to manage entire building projects.

Professional interior designers usually hold diplomas or degrees and seek membership of the British Institute of Interior Design (BIID) or the Chartered Society of Designers (CSD), to demonstrate competence. However, the industry is largely unregulated, so checking a designer's experience is essential before hiring.

Do I need an Architect to design my project?

Hiring a skilled architect can be invaluable. They manage all stages of your project and bring design expertise that saves time and money. Architects can take on projects of any size, from loft conversions to new builds.

However, if your main goal is adding floor space without much design input, a chartered architectural technologist may suffice at a lower cost. Also, if you have fixed ideas and don’t need design guidance, an architect may not be the best choice.

For large scale renovations, new builds and projects in heritage settings, you should consider appointing an architect.

Who else might I need to involve?

In addition to an architect (or other designer), you may also need to appoint these consultants:

  • Structural Engineer: Designs structural elements and provides calculations for building regulations.
  • Party Wall Surveyor: Advises on party wall agreements if building close to or on a boundary.
  • Quantity Surveyor: For specialist cost advice and detailed pricing documents (eg a bill of quantities).
  • Heating Engineer: To design and install specialist systems like heat pumps.
  • Mechanical Engineer: To design and install mechanical systems like Mechanical Ventilation Heat Recovery (MVHR).

An architect can help you appoint them and coordinate their work ensuring it’s seamlessly integrated into the design.
