How to Start an Architecture Practice in the UK

Is Starting an Architecture Practice Right for You?

Demand for architects is cyclical, moving with interest rates, house prices and construction confidence, but the small-project market of extensions, loft conversions, refurbishments and self-builds is large and local, and it is where most new practices start. Clients choose on the quality of the work they can see, on whether they feel listened to and on confidence that you will steer them through planning and building control. Practices that do well early have a recognisable approach and a few projects photographed beautifully.

Running a practice is different from being a project architect. You find the work, write the fee proposals, negotiate the appointment, manage cash flow across stages that may stall at planning for months, carry the professional liability and still do the drawing. Fees arrive in stage payments, projects pause when clients hesitate, and a planning refusal can empty a quarter's income. People who thrive are good with clients, organised about money and realistic about how much design time a sole practitioner actually gets.

Most founders are registered architects with several years of post-registration experience, often having run projects at a practice and quietly completed a friend's extension on the side. Registration is the legal minimum, but experience of contracts, planning, building regulations and site is what keeps a small practice out of trouble. If you are not yet registered, finish the route to registration first, because practising under the title before then is an offence, and build on the experience you gain meanwhile.

Qualifications, Registrations and Rules

• Registration with the Architects Registration Board. Under the Architects Act 1997 only people on the ARB register may use the title architect in business or practice, and misuse is a criminal offence that ARB can prosecute. Registration usually follows recognised qualifications and practical experience, with an annual retention fee, and ARB is changing its education and registration routes, so check its current requirements. Unregistered designers can still offer design services, provided they do not use the title.
• Business names and the protected title. A company or partnership may use the word architect in its name only if a registered architect is in control and management of all the architectural work, and a limited company or LLP must apply to ARB for permission first. Only the word architect is protected, so architectural and architecture are not policed, but implying registration you do not hold still causes problems. Read ARB's title guidance before registering a name.
• The Architects Code and professional indemnity insurance. ARB's Architects Code of Conduct and Practice, revised from September 2025, sets the standards every registered architect must meet, including adequate and appropriate professional indemnity insurance in place before taking on any work and run-off cover after you stop. Insurers price on turnover, project types and experience, and some work, such as cladding or basements, is harder to insure. ARB publishes insurance guidance and expects you to follow it.
• RIBA Chartered Practice status. Membership of the Royal Institute of British Architects is voluntary, and so is Chartered Practice status, which requires at least one full-time principal to be an RIBA Chartered Member, a proportion of chartered staff, valid professional indemnity insurance and policies on quality, health and safety, employment, environmental management and equality. Some clients and competitions ask for it, and it brings a directory listing and standard contracts, so decide early whether it fits.
• Appointment terms and the Plan of Work. The Code expects written terms of engagement agreed before work starts, covering scope, the fee and how it is calculated, responsibilities, insurance, complaints handling and how either side can end the appointment. Most practices base them on the RIBA Plan of Work, whose eight stages run from strategic definition and briefing through concept, spatial coordination and technical design to construction, handover and use, and quote stage by stage.
• Planning, building regulations and health and safety. Clients expect you to steer them through planning permission, permitted development, listed building and conservation area consent and the Building Regulations, which differ between England, Wales, Scotland and Northern Ireland, so you need working knowledge of the nation you practise in. Under the Construction (Design and Management) Regulations you have designer duties on every project and may be principal designer, with the Health and Safety Executive's guidance as the reference.

Setting Up the Business

• Sole trader, partnership or limited company. Many sole practitioners start as sole traders and incorporate as fees and liability grow, while partnerships and limited companies suit practices starting with two or more founders. The structure affects tax, personal exposure if a claim exceeds your insurance, and how you take on co-directors later, so take an accountant's advice before deciding, and remember that a company using the word architect needs ARB's permission for the name.
• HMRC and VAT. Register with HMRC for Self Assessment or Corporation Tax when you start, and plan for VAT, which most practices must charge once fees pass the threshold published on GOV.UK. Private homeowners cannot reclaim it, which makes you dearer to them than an unregistered designer below the threshold, so factor it into your fee proposals and ask your accountant about the timing of registration.
• Business banking and stage invoicing. Open a business account before the first fee and run every subscription and expense through it. Choose bookkeeping software that handles invoices by project stage, payments on account and expenses such as printing and travel recharged to clients. Because fees arrive at stage ends, keep a cash flow forecast by project and update it whenever a client pauses, which they will.
• Insurance beyond indemnity. Professional indemnity is the core cover and the one the Code expects, but a practice also needs public liability for site visits, employers' liability as soon as anyone works for you, and cover for computers, equipment and the data on them. Cyber cover matters because you hold clients' plans and personal details, and legal expenses cover can help with fee disputes.
• Software licences and subscriptions. A small practice typically needs drawing and modelling software, often with the building information modelling capability clients and consultants increasingly expect, rendering and presentation tools, a specification and contracts service, cloud storage with proper backup, and project and time tracking to see which stages make money. Licences are usually annual or monthly subscriptions per user and are among your largest running costs.
• Data protection and the ICO. You hold clients' names, addresses, finances and drawings of their homes, so pay the data protection fee to the Information Commissioner's Office, publish a privacy notice and secure your files and email. Site photographs showing people, neighbours' properties in survey drawings and planning submissions that become public all raise questions worth thinking through before the first project.

Start-up Costs and What You Need

Starting an architecture practice is cheaper than most businesses in equipment and dearer in overheads. The main items are registration and professional subscriptions, professional indemnity insurance, software licences, a capable computer and large monitor, a printer that handles drawings or a print bureau account, survey equipment such as a laser measure, and a website with a proper portfolio. Add the model-making materials, site boots and travel that small projects involve.

The choice between working from home and renting a studio shapes the budget. Home works for many sole practitioners, with client meetings on site and a good video set-up, while a desk in a shared studio brings company, collaboration and a place to meet clients at a monthly cost. Take the studio when the work and the team justify it rather than at launch.

The real cost is the wait between stages. A project may spend months in planning before the next fee falls due, and clients pause for finance, weather and nerves. Plan for several months of living costs, build a forecast by project stage, add a contingency for a laptop failure or a stalled project, and price your fees to recover everything on the list, because the overheads continue whether or not the planning committee meets.

Pricing Your Work

Architects charge in three main ways. A percentage of the construction cost is traditional and scales with the project, but it moves as the budget does and clients may see it as a reason to inflate the build. A fixed fee for each stage, agreed from an estimate of the hours involved, gives clients certainty and rewards efficiency. Time charges suit feasibility work, surveys and unclear scopes. Many small practices mix them: time for the early stages, fixed fees once the brief is settled.

Whatever the basis, work it back to your real costs. Add up the practice overheads and the salary you need, divide by the hours you can realistically charge once marketing, administration and unpaid competitions are removed, and you have the hourly rate every fee must recover. Then estimate the hours for each stage honestly, because the hours a small house extension takes are routinely underestimated.

Set out in the appointment what each stage includes, what is extra, how additional services such as interior design or party wall advice are charged, when invoices are issued and how long clients have to pay. Take a payment on account before starting, invoice at the end of each stage rather than at completion, and say clearly what happens to fees if planning is refused or the client pauses the project.

Finding Your First Customers

• Referrals and former colleagues. Friends, family, former colleagues and the contractors and consultants you have worked with are the first source of projects for almost every new practice. Tell everyone what you are doing and the work you want, stay in touch with the engineers and consultants from past projects, and ask every satisfied client to recommend you to one neighbour.
• Planning consultants, builders and estate agents. Planning consultants meet homeowners who need drawings, builders meet clients who need plans before they can quote, and estate agents meet buyers planning to extend. Each is asked for an architect regularly and prefers one who responds quickly and makes their job easier, so introduce yourself and reciprocate with referrals.
• House extensions and local search. Most homeowners planning an extension search for an architect near them, look at projects and read reviews before enquiring. A Google Business Profile, a website with a page for the home projects you do and a few completed examples, and early reviews bring enquiries that no design award will, and getting found on Google takes months, so start early.
• Houzz, Instagram and the visual platforms. Houzz, Instagram and Pinterest are where homeowners collect ideas for months before they appoint anyone, and a practice that posts real projects, drawings and progress photographs consistently gets found there. Treat them as a portfolio with a conversation attached, reply to every message, and link back to the website where the enquiry can become a meeting.
• The first well-photographed project. A new practice's most valuable marketing asset is one finished project photographed properly, with the client's permission, in good light. It fills the website, the social accounts, the directory listings and the press release to local and design media, and it earns the second project. Budget for a professional photographer from the start, and photograph the process too.
• Competitions, frameworks and larger clients. Open competitions, small public frameworks and work for developers and businesses can arrive later, once there is a portfolio, Chartered Practice status if you want it and the insurance levels they demand. They take time and unpaid effort to win, so treat them as a second-year goal rather than a launch channel.

Your Website and Online Presence

An architect's website is judged the way buildings are, so the work has to lead: large, well-photographed projects with drawings and a short story about the brief, the constraints and the result. Beneath that, clients want to know what you do mapped to the RIBA stages, how you charge, how planning works, who you are and that you are registered with ARB and insured, and an easy way to book an initial conversation. Keep the copy plain and confident rather than theoretical.

Have the website live before the first project completes, even with a single project or your best work from previous employment with credit given, because every referral will look you up. A startup website checklist covers the domain, hosting and legal pages, and the site should grow one project page at a time, each photographed properly, as the practice builds its portfolio.

When you are ready for a website, our startup architecture practice website design page explains what a new architecture practice needs on day one, our architects website design page covers the full picture for an established business, and architects website design prices sets out what it costs. Startup websites start from £2,400, and our startup website checklist lists what to have ready.

Mistakes New Architecture Practices Make

• Using the title architect, or a business name containing it, before registration and ARB's permission are in place, which is a criminal offence rather than a technicality.
• Starting a friend's extension without written terms or confirmed insurance, and discovering what that means when the builder's work fails and the friend blames the drawings.
• Quoting a percentage fee on a budget the client has guessed, then working for months on a project whose real cost was never agreed.
• Underestimating the hours a small domestic project takes, especially the planning stage, so the fixed fee is spent before technical design begins.
• Spending the first year on unpaid competitions and speculative work while the referrals that would have paid the bills went unfollowed.
• Leaving the website and portfolio until the first project completes, so a year of referrals finds nothing to look at.
• Taking on every enquiry regardless of budget or location, so the diary fills with unviable projects and site visits rather than fee-earning work.
