How to start a consulting business from scratch

Independent consulting is one of the highest-margin service businesses you can start — if you specialise correctly. Here's the realistic path from leaving your job to a sustainable practice earning £150k+.

Quick answer

Starting a consulting business takes 2–4 weeks and under £500 of startup costs. The hardest parts aren't the consulting work — they're niching specifically, pricing confidently, and getting visible. Most new consultants earn £40,000–£100,000 in year one (often from ex-employer engagements); specialist consultants with strong content presence reach £200,000–£500,000+ within 2–4 years. The path: niche specifically (industry + problem), build LinkedIn content for 12 months, charge premium fees from day one, build to retainer relationships.

Step-by-step

Niche specifically (industry + problem)

Generic 'consultant' competes globally and undercharges. Specialists thrive. Best niche structure: a specific industry vertical + a specific problem you solve. 'Marketing consultant' is invisible; 'B2B SaaS demand-gen consultant for Series A startups stuck at £2M ARR' is bookable and commands £15,000–£40,000 engagements. Pick a niche where you have lived experience (years in that industry), where premium fees exist, and where you can articulate specific outcomes. Niche down obsessively before any marketing — generalist positioning kills consulting businesses.

Get legal and operational setup

Register as a sole trader (UK: free, 10 minutes online) or LLC (US: $50–$200). Get professional indemnity insurance (£200–£600/year for typical consulting work). Open a separate business bank account. Set up basic operational tools: a simple contract template (Bonsai, AND.CO, or a lawyer-drafted one), an invoicing tool (Xero, FreeAgent, or QuickBooks), a CRM or even simple Notion for client tracking. Most consulting businesses fail on operational chaos, not consulting skill — get systems in place from day one.

Set premium pricing from day one

New consultants almost universally undercharge. Realistic 2026 rates for niche-positioned independent consultants: day rates £1,200–£3,500+. Project pricing £8,000–£60,000+ depending on scope. Monthly retainers £4,000–£20,000+. Don't apologise for your rates or offer 'introductory pricing' that traps you at low margins. Premium clients pay premium fees and trust you more for charging properly. Calculate your true cost: target £150,000–£300,000+ annual revenue from 8–12 active clients, working back to per-engagement pricing.

Get first clients from your existing network

Almost every successful new consultant's first 3–5 clients come from their existing network — ex-colleagues, ex-managers, ex-clients from employed roles. Three moves. Send a clear announcement to your network ('I'm leaving X to start independent consulting focused on Y; if you or anyone in your network is wrestling with Z, I'd love to chat'). Have specific conversations with 20–30 people in your first month about what they need help with. Convert 3–5 into first paid engagements. Most consulting businesses' first £100k of revenue comes from network, not marketing.

Build LinkedIn as your discovery engine

Beyond network, LinkedIn is where B2B consulting buyers spend time. Post 3–5 times a week with niche-relevant content: opinion on industry challenges, specific frameworks you use with clients, anonymised case studies, behind-the-scenes from advisory work. Aim for 12–24 months of consistent posting before judging results. The consultants earning £300k+ all built compound LinkedIn audiences patiently. Don't gate-keep frameworks — share genuinely useful content publicly.

Build a website that signals premium

Five things matter on a consulting website. Niche positioning above the fold ('I help B2B SaaS founders scale from £1M to £5M ARR'). 3–5 in-depth case studies with named clients and specific outcomes. Clear engagement models — typically project-based or retainer, not hourly. Real client testimonials with named businesses. A direct CTA (typically a discovery-call booking link). Adviita builds this kind of consulting positioning page in minutes.

Build to retainer relationships

Project work is unpredictable; retainers stabilise income. After your first 3–5 successful engagements, propose monthly retainers to your best clients: 'I'd like to be your ongoing strategic partner on X — retained at £8,000/month for two days of advisory work and Slack/email support'. Retainers convert at 30–50% with successful project clients. 5 active retainers totalling £40,000/month is a stable, premium consulting business. Most consultants spend year 1 on projects and year 2+ converting to retainers.

Tips & best practices

▸Get specific about who you're NOT for. Saying 'I don't work with pre-revenue startups' or 'I don't take corporate clients under £10M revenue' signals premium and filters out poor-fit prospects.
▸Discovery calls are qualifying conversations, not sales pitches. Ask hard questions about whether your prospect is ready to act and willing to invest. Saying 'this isn't a fit' confidently builds your premium positioning.
▸Build an email list separate from LinkedIn. A 1,500-person email list with relevant content produces consistent enquiries even when LinkedIn algorithms shift.

Common questions

How much can an independent consultant earn?

Generalist consultants competing globally: £40,000–£80,000. Niche-positioned consultants with strong content presence: £150,000–£400,000. Top niche specialists with strong frameworks, retainer relationships, and corporate work: £500,000–£2,000,000+.

Do I need to leave my job before starting?

Not necessarily. Many successful consulting businesses are launched on the side first — taking on 1–2 evening/weekend clients to build runway and validate the niche before going full-time. Aim for 3–6 months of consulting revenue equivalent to your salary before fully transitioning if cash flow is a concern.

Should I focus on one industry or stay industry-agnostic?

One industry, almost always. Industry specialism is the single biggest predictor of premium fees. Industry-agnostic consultants compete with everyone and command average fees; industry specialists become 'the' person for their niche and command premium fees plus inbound enquiries.

What's the biggest mistake new consultants make?

Hourly billing. Hourly transfers all risk to the client (who will pad budgets) and caps your earning at hours worked. Project pricing or retainer pricing aligns incentives and supports premium fees. Move away from hourly within your first 6 months.
