Business Plan Writers in London: Written for the Funder Who Will Read Them
London concentrates more of the things a business plan has to satisfy than anywhere else in the UK: the densest funding market in Europe, the largest population of international founders navigating UK visa routes, and high-street and commercial lenders headquartered across the City and Canary Wharf.
SGI Consultants is a London business plan writing practice, based in Fulham, producing investor-grade documentation for founders and businesses across the capital, tailored to what each funder actually needs to see.
We have written business plans since 2014 and produced investor-grade documentation for 2,000+ clients, facilitating more than £250M in total capital secured at a 90% funding success rate.
We can meet you in person across London to work through your plan, which matters when the documentation has to withstand the scrutiny of a London investor committee or a bank's credit team.
Who Delivers This Service
Your business plan will be led by Kurt Graver — Accountant, MBA, Founder of SGI Consultants — supported by a qualified team of business plan specialists with experience across all funding types. Kurt personally oversees every plan, ensuring the 90% funding success rate that has defined SGI's track record across 2,000+ client engagements.
What Our UK Business Plan Writers Deliver
Unlike generic business plan writing services that rely on templates and automated software, our professional business plan writers take a bespoke approach. We don’t just write—we become your strategic partner, understanding your market, validating your assumptions, and crafting documentation that withstands forensic due diligence.
The difference between funded businesses and rejected applications often comes down to the quality of the documentation. Investors and banks review hundreds of business plans monthly. Yours needs to break through the clutter with institutional-grade analysis, defensible financial projections, and a compelling narrative that communicates competitive advantage.
Business Plans Written for UK & Global Clients
Funding Success Rate
Total Capital Secured via Our Plans
Day Turnaround (Standard to Express)
These figures are verified outcomes from real business plan engagements. Our funding success rate of 90% compares with a national average of 45% -- the difference is not due to chance. It is the result of a structured approach to business planning that treats documentation as a strategic instrument, rather than a box-ticking exercise.
Who We Work With
- Founders applying for a government-backed Start Up Loan. You need a plan and a personal survival budget that an adviser can approve without coming back with questions. The assessment is closer to a credit process than an investment one, and the plan needs to read that way.
- Established businesses approaching their bank. Your credit team is assessing serviceability, security and the credibility of your forecast. We build the plan around those three questions and evidence each one.
- Businesses applying to Innovate UK or a sector grant body. Assessors score against published criteria. A plan that does not map to the criteria loses marks it never needed to lose, however strong the underlying project.
- Founders raising equity from angels or venture capital. The deck opens the door, and the plan and model decide whether it stays open. Consistency between the three is what the investor is testing.
- Applicants on the Innovator Founder or Global Talent routes. The plan is assessed for endorsement against Home Office criteria, and we write it alongside your immigration adviser so the two documents agree.
Why London Businesses Come to us
Investor business plans for a crowded funding market. London holds the largest concentration of angels, venture capital and family offices in Europe, and they review a high volume of pitches. A plan that stands out needs institutional-grade financial modelling, bottom-up market sizing and a narrative that aligns perfectly with the numbers. That is what we build.
Visa business plans for international founders. London is the primary destination for entrepreneurs relocating to the UK, and the Innovator Founder and related routes require plans that satisfy both the Home Office criteria and the Designated Organisation endorsement standards. This is one of the most common reasons London-based founders come to us.
Bank and lender plans. With the major UK banks and commercial lenders concentrated in London, we prepare documentation focused on the credit-assessment process: cash flow forecasting, debt serviceability, working capital management, and risk mitigation.
Plans across London's sectors. From fintech and professional services in the City, to hospitality and retail across the boroughs, to creative and consumer ventures in the west and east, we build plans grounded in real-sector benchmarks rather than generic templates.
Our Business Plan Writing Services
We cover every funding context, from government-backed Start Up Loans to multi-million-pound Series B rounds. A senior consultant with direct experience in your funding type and sector leads every engagement.
Investor Business Plans (Venture Capital, Angel & Private Equity)
For equity funding from sophisticated investors. We build investment theses with financial models incorporating CAC, LTV, churn and cohort analysis, total addressable market analysis, competitive intelligence across 10 to 20 competitors, scenario planning, exit-strategy articulation and a pitch deck on higher tiers.
Investor Pitch Decks
(Included with Premium and Elite Investor Plans)
Secure the investor meeting by communicating your opportunity in under four minutes—and then sustain credibility through a due diligence process in which every slide is checked against every number in the business plan.
Visa & Immigration Business Plans
Plans that satisfy both Home Office immigration criteria and Designated Organisation endorsement standards simultaneously, covering the innovation criterion, UK market viability, scalability and job-creation pathway.
Bank Loan & Lender Business Plans
For high-street banks and commercial lenders, who want evidence that you can service debt through economic cycles. We address detailed cash flow forecasting, break-even analysis, working capital management, collateral documentation and comprehensive risk mitigation.
Startup Loan Business Plans
Grant Application Business Plans
Documentation structured around each programme's assessment criteria, whether Innovate UK, regional development or sector-specific schemes, addressing the outcomes each scheme exists to achieve.
Franchise Business Plans
Specialist Regulatory & Compliance Business Plans
Strategic Business Planning & Consulting
Credible roadmaps for expansion, product launch, market entry or operational scaling that support both internal decision-making and external funding requirements.
What Makes SGI Business Plan Writers Different
There is no shortage of business plan writing options in London. Freelancers on Upwork, template services, AI generation tools, and single-focus consultancies covering investor plans or visa documentation -- the options are numerous and, at the lower end, very cheap.
What you will not find anywhere else is the breadth and depth of capability we offer across every funding type, every business stage, and every regulatory context -- with a verified 90% success rate across all of them.
Senior Consultant Direct Engagement. Every business plan is written by a senior consultant with operational business experience -- not a junior analyst, not an offshore team, and not an AI tool with your name inserted. Our business plan writers have held board positions, owned businesses, and secured funding themselves. This is practical expertise, not academic theory.
Institutional-Grade Financial Modelling. Our financial models match the standards that institutional investors and high-street banks apply when evaluating documentation. We build dynamic spreadsheets with assumption logs, sensitivity toggles, and scenario planning, allowing investors to stress-test your business in real time. Every projection is grounded in defensible logic derived from sector benchmarks and your specific business model.
Comprehensive Market Intelligence. We do not rely on free online sources for market analysis. Our research uses professional databases, industry reports, and primary research to size your Total Addressable Market, Serviceable Addressable Market, and Serviceable Obtainable Market. We analyse 10 to 20 direct competitors to identify positioning opportunities and competitive weaknesses you can exploit.
Narrative-Financial Alignment. The most common cause of funding rejection among competent businesses is misalignment between the narrative and the numbers. We ensure perfect consistency across your business plan, financial model, and pitch deck where applicable. Discrepancies are red flags—we eliminate them before submission.
Full-Spectrum Coverage. Most business plan consultancies limit you to their narrow area of expertise. An investor-focused firm cannot help you with a visa plan. A grant-writing specialist may not understand the financial modelling requirements for a bank application. When your funding strategy spans multiple sources -- which sophisticated fundraising often does -- you need advisors who understand how each element interconnects. SGI is the only London consultancy that covers the complete spectrum under one roof, with documented success across the board.

Our 5-Phase Business Planning Process
After producing business plans for 2,000+ businesses, we have refined an approach that consistently delivers funding success. Each phase builds on the previous, creating documentation that withstands forensic scrutiny rather than simply looking professional.
Phase 1: Strategic Foundation (Week 1)
Every engagement begins with comprehensive discovery. We conduct structured sessions to understand your business model, competitive positioning, target market, and funding objectives. Without a solid strategic foundation, even sophisticated financial models fail to convince funders.
Phase 2: Market Intelligence & Validation (Weeks 1-2)
We conduct primary and secondary research covering industry dynamics, customer segments, competitive positioning, and regulatory requirements. This includes TAM/SAM/SOM sizing using professional databases and competitive intelligence on 10-20 direct rivals. Evidence-based market analysis is what separates professional documentation from template-based approaches.
Phase 3: Financial Modelling & Projections (Weeks 2-3)
We build dynamic financial models incorporating revenue projections, cost structures, cash flow forecasting, profitability timelines, and sensitivity scenarios. Every assumption is defensible. Banks scrutinise debt servicing capacity; equity investors evaluate unit economics and scalability. Our models address both perspectives with appropriate rigour.
Phase 4: Strategic Documentation (Weeks 3-4)
With research and financial models complete, we craft compelling narratives that integrate market intelligence, competitive positioning, operational roadmaps, management credentials, and financial projections into cohesive documentation. Perfect alignment between narrative and numbers is non-negotiable - discrepancies destroy credibility instantly.
Phase 5: Refinement & Optimisation (Week 4-5)
The final phase involves collaborative refinement. We incorporate your feedback, stress-test assumptions, optimise for specific audiences (banks, investors, and visa authorities), and prepare presentation materials. This iterative process typically requires one to two revision rounds. Rushed plans frequently skip this phase, which is a primary reason they fail.
Total timeline: 4-5 weeks from engagement to final delivery, significantly faster than the 3-6 months entrepreneurs typically spend on self-directed business planning - and with substantially higher funding success rates.

Frequently Asked Questions (FAQs)
Yes. We are based at 20 Dawes Road in Fulham, southwest London, and we work with founders across every London borough. You can meet your consultant in person or run the whole engagement remotely, whichever suits you. Most of the process happens over structured calls, but for London-based clients an in-person session is always available.
London is where most of the UK's investors, banks and visa endorsing bodies sit, and a plan written for a London funder needs to reflect how that funder actually evaluates applications. A London-based team understands the local market, the rents and salary benchmarks that make London projections credible, and the expectations of London lenders and investors. Overseas template services rarely capture any of that, which is one of the most common reasons London applications are rejected.
Yes. London concentrates the UK's venture capital, angel networks and private equity, alongside the head offices of the major banks and the British Business Bank, and each assesses a plan differently. We build your documentation around the specific funder you are approaching, whether that is an early-stage seed fund in Shoreditch, a private equity house in Mayfair or a high-street bank. The plan is shaped by how that funder scores applications, not by a generic template.
All of them. We work with founders across the City, Shoreditch and Old Street, Canary Wharf, Mayfair, Camden, Hackney, Stratford, Croydon and the outer boroughs, as well as the wider Greater London area. Our remote-capable model means your location within London never affects the service or the price.
Our pricing is fixed across four tiers, from £750 to £3,500, and it is the same whether you are based in London or elsewhere in the UK. Many London providers charge a premium for the postcode; we do not. After a free consultation we give you a transparent, fixed-price quote with no hidden fees and no success fees, so you can see exactly what you are paying for. For the full breakdown, see our pricing and competitive comparison page.
Yes, and it is one of our most common London engagements. London is the leading destination for international founders on the Innovator Founder and Global Talent routes, and these plans must satisfy both Home Office criteria and your endorsing body at the same time. We build the documentation to that standard, evidencing innovation, UK viability and job creation. See our visa business plans page for the detail.
Yes. For London founders raising angel, seed or Series A funding, we build the investment thesis, the financial model with proper unit economics, and the pitch deck that stand up to investor due diligence. We keep the narrative and the numbers perfectly aligned, so nothing unravels when a London investor digs into the detail. Our investor-ready business plans page explains the approach.
A properly researched plan takes 4 to 5 weeks end to end. Where a London funding round or application has a tighter deadline and your information is ready at the outset, express turnarounds of 10 to 14 days are available. We will tell you honestly at the start whether your timeline is realistic for the plan you actually need.
No honest business plan writer can guarantee funding, and you should be cautious of any who claim to. What we commit to is a plan built to the standard London funders expect, with defensible projections and revision rounds until you are satisfied. Our 90% funding success rate is nearly double the national average; the minority of applications that do not succeed usually face issues beyond the plan itself, such as credit history or market timing.
We are London-based but work with clients across the whole UK, including Manchester, Birmingham, Cambridge, Edinburgh, Glasgow and Bristol, as well as international founders. If you are searching specifically for business plan writers in London, you have the advantage of a local team; if you are elsewhere, our remote model delivers exactly the same service. You can also see our full national service on our business plan writers page.
Most London providers specialise in one niche, an investor-plan boutique, a visa specialist or a low-cost template service, and many freelancers work alone without real finance depth. SGI covers every funding type, equity, debt, grants, visas and regulatory approval, with senior consultants who have held board positions and raised funding themselves. We sit deliberately between London's template services and Big Four pricing: bespoke and senior-led, but built for founder and SME budgets, and for clients who need it we continue as a fractional strategy office once the plan is written.
