How to start an architecture firm in the UK

Most architecture practices begin with one or two architects leaving a larger firm, often with a first client or two in mind. The design skills are already there; what catches founders out is the business side: insurance, appointments, cash flow between fee stages and how long it takes before a lender will treat the practice as established. This guide walks through the steps in order. Smart Funding Solutions is a finance broker: we arrange business funding from around £10,000 to £500,000+, with larger facilities available in suitable cases, and our architect practice finance page covers borrowing once the practice is trading.

01Step 1: Check your registration and your contract

Only people on the register kept by the Architects Registration Board can call themselves architects in business. If you are not yet registered, the ARB's guidance on registering for the first time explains the routes. Unregistered designers can still offer architectural design services, but cannot use the title.

Before resigning, read your employment contract. Restrictive covenants commonly stop departing staff from soliciting the employer's clients or poaching colleagues for a period. Taking a client who approached you may still be a breach if the covenant is broad. A short consultation with an employment solicitor costs far less than a dispute that freezes your first commission.

02Step 2: Choose a structure

Our guides on sole trader or limited company and limited company or LLP cover the trade-offs. Whatever you choose, agree in writing between co-founders how profits are shared, who owns the name, and what happens if one leaves.

03Step 3: Arrange insurance before the first commission

Registered architects must hold adequate professional indemnity insurance for the work they do. A new practice with no claims history and no turnover record may find the first premium higher than expected, and some clients, particularly developers and public bodies, will specify minimum limits in the appointment. Ask a specialist broker for quotes before pricing your first fee proposal, and add employers' liability once you take on staff. Our page on PII premium finance explains how practices spread the premium.

04Step 4: Set up appointments and billing

Cash flow in architecture is decided at the appointment stage. Agree the scope, fee and payment stages in writing, using a standard form professional services contract or a well-drafted letter of appointment, before starting work. Bill at each work stage, or monthly on larger jobs, rather than waiting for a project milestone that may be delayed by planning.

For private householder clients, consumer protection law applies. Contracts agreed away from your office or online can carry a cancellation period, and starting work before it ends without the client's written request can leave fees unrecoverable. Take a deposit or initial fee for concept work where you can.

05Step 5: Budget the first year

Startup costs for a small practice are modest compared with many businesses, but the gap before the first fee arrives is long. Typical costs include:

• CAD and BIM software subscriptions and rendering tools
• Workstations, a large-format printer or plotting service, and a laser measure or survey kit
• Professional indemnity insurance and ARB registration fees, plus RIBA membership if you join
• Workspace: home, a desk in a shared studio or a small office lease
• Accountancy, a website and practice management software
• Living costs for the founders until fees cover them

Illustration. Two founders budget £45,000 for set-up and fixed costs over the first year, plus £60,000 to cover their own drawings for six months. Their first two commissions are worth £80,000 in fees, but the first significant stage payment is not expected until month four. The plan needs cash for at least four months of costs before any income, with a buffer for a project stalling at planning. These figures are hypothetical.

Check the VAT registration rules: you must register once taxable turnover passes the threshold, and voluntary registration can help when most clients are VAT-registered businesses.

06Step 6: Fund the start

Savings and founder capital

Most practices start this way. It keeps control with the founders and avoids repayments while income is uncertain.

Start Up Loans

The government-backed Start Up Loans programme lends to individuals starting or in the early years of a business, with mentoring alongside. Each founder applies personally, so two founders can each apply. See our page on start-up business loans for how this compares with other options.

Asset finance

Workstations and printers can be spread over two to four years with equipment finance, which some lenders will consider for new businesses, especially with a deposit. Our guide to architectural equipment finance goes into more detail.

Business loans once trading

Many lenders want to see at least six to twelve months of trading and bank statements before offering an unsecured business loan, and some want filed accounts. Borrowing of £25,000 or less by sole traders and small partnerships can be regulated consumer credit, which brings additional protections.

Startup costs for a small practice are modest compared with many businesses, but the gap before the first fee arrives is long.

07Step 7: Plan for the second year

The second year brings the first corporation tax or self-assessment bill, a PII renewal priced on your actual turnover and often the first hire. Set aside tax monthly from fees received, keep a pipeline sheet showing expected billing by stage, and produce simple management accounts. That record is exactly what a lender will want when you apply for a working capital facility or a loan to grow. A written business plan for funding helps at the same point.

08What lenders look for in a young practice

When the practice first applies for equipment finance or a small loan, lenders have little history to go on, so they look closely at a few signals:

• Fees actually billed: bank statements showing stage payments arriving, rather than a list of hoped-for commissions.
• The pipeline: signed appointments with fee stages and expected billing dates.
• Client spread: whether one developer or one framework accounts for most of the income.
• Insurance in place: current PII at a level that matches the work you take on.
• Founders' credit and commitment: personal credit files and the money the founders have already put in.

10When to talk to us

Once the practice has a few months of trading, we can look at whether lenders on our panel would consider equipment finance, a start-up loan alternative or a small working capital facility. Lenders make the decision. It is free to enquire; any broker fee is disclosed separately before you proceed.
