A mortgage broker business plan is worth writing properly. Not because you need a formal document for a bank (most brokers don't — you can self-fund through the first 12 months), but because writing it forces you to be honest about revenue assumptions, client acquisition costs, and how long it genuinely takes to reach sustainable income. This guide gives you a framework that matches how UK brokers actually build their businesses in 2026 — not the optimistic version you'll see in the sales pitch of a course or compliance provider.

The honest overview

If you're thinking about starting a mortgage broker business in 2026, here's the blunt summary of what it takes:

  • Qualification cost: CeMAP typically £1,200-£2,000 depending on route, 3-6 months part-time study
  • Authorisation cost: £500-£2,000 to join a network as an appointed representative, or £3,000-£8,000 to become directly authorised (plus ongoing fees)
  • Year 1 realistic revenue: £25,000-£60,000 gross procuration fees, before tax and costs
  • Year 1 realistic profit: £10,000-£40,000 for a solo broker working full-time, possibly negative if you invest heavily in marketing
  • Break-even point: Typically 6-12 months if you have a network/referral base at launch; 12-18 months if starting from cold
  • Profitable full-time income: Usually achievable by year 2-3 for most committed brokers who stay in the market

Roughly 30-40% of new brokers exit the industry within 18 months, mostly because revenue ramp is slower than expected. The brokers who succeed are those who plan for a realistic ramp and have the savings or alternative income to survive it.

Revenue model

UK mortgage brokers earn from three main revenue streams:

1. Procuration fees (the main revenue source)

Paid by the lender on mortgage completion. Typical 2026 proc fees:

  • Standard residential mortgage: 0.35-0.45% of loan value (average £700-£1,200 per case on a £200,000 mortgage)
  • Buy-to-let mortgage: 0.45-0.70% (average £1,000-£1,800 per case)
  • Specialist / adverse credit: 0.50-1.00% (average £1,000-£2,500 per case)
  • Bridging finance: 1.0-2.0% (average £2,000-£8,000 per case)
  • Commercial mortgage: 0.75-1.5% (average £3,000-£15,000 per case)

2. Client fees

Charged directly to the client. Typical structures: flat fee (£295-£750 for residential), percentage (0.4-1% of loan), or a combination. Around 70% of UK brokers charge some form of client fee — fee-based brokers typically earn 30-60% more per case than commission-only brokers serving the same client base.

3. Protection commission

Life insurance, critical illness, and income protection sold alongside mortgages. Indicative commissions:

  • Term life insurance: £150-£400 per policy
  • Critical illness cover: £400-£900 per policy
  • Income protection: £200-£600 per policy
  • Combined life + CI + IP: £700-£1,500 per case

Brokers who consistently cross-sell protection typically earn 40-70% more per mortgage client than those who don't.

Typical per-case revenue

Combined, a standard residential mortgage case with a client fee and a protection attachment generates £1,500-£2,500 in broker revenue. Specialist cases and higher loan sizes can push this to £3,000-£8,000. Over a year, a competent solo broker completing 50-80 cases earns £75,000-£200,000 gross broker revenue before costs.

Cost structure

Typical annual costs for a UK solo mortgage broker:

  • Network / AR fees: £4,000-£12,000 (if appointed rep) or £8,000-£20,000 (if directly authorised including PII, FCA fees, compliance support)
  • CRM & sourcing systems: £800-£2,400 (Twenty7Tec, Knowledge Bank, Intelligent Office, or network-provided)
  • Email, phone, office tech: £600-£1,500
  • Accountancy and bookkeeping: £800-£2,500
  • Professional indemnity (if DA): £1,500-£4,000
  • Marketing (paid advertising, leads, or referral fees): £3,000-£30,000+ depending on strategy
  • Continuous professional development: £300-£1,000

Total annual fixed costs for a solo broker typically run £12,000-£25,000 if appointed representative, or £18,000-£40,000 if directly authorised with own marketing budget. Plan for £15,000-£20,000 in year 1 unless you're investing heavily in advertising.

Year 1 milestones

Months 1-3: Setup

  • CeMAP passed (if not already)
  • Authorisation secured (AR agreement signed or DA application in progress)
  • PI cover in place (if DA)
  • CRM and sourcing system set up
  • Initial referral conversations with estate agents, solicitors, accountants, financial planners in your area
  • Target: 0-3 cases in month 3 if network pre-exists; likely 0 if starting cold

Months 4-6: First cases

  • Complete 2-5 cases per month by month 6
  • Establish monthly networking routine (minimum 2 client-facing meetings/week)
  • Test one paid acquisition channel on small budget (Google Ads, Facebook, or bought leads)
  • Target revenue: £2,000-£8,000/month gross broker revenue

Months 7-12: Pipeline building

  • Complete 4-8 cases per month by month 12
  • Establish a follow-up system for speaking with warm leads consistently
  • Refine protection cross-sell rate — aim for 40%+ of mortgage clients taking at least one protection product
  • Target revenue: £5,000-£15,000/month gross broker revenue
  • Year 1 total: 30-70 completed cases, £25,000-£60,000 gross revenue

Year 2 milestones

Year 2 is typically when a mortgage broker business either becomes sustainably profitable or struggles. The brokers who succeed in year 2 share three characteristics:

  • Consistent acquisition channel: by month 18, at least one acquisition channel is reliably producing 10+ new cases per month (referrals, paid ads, or purchased leads)
  • Improving conversion: year 2 conversion on enquiries is typically 30-50% higher than year 1 because you've refined your process and presentation
  • Repeat and referral business: year 2 should see 15-25% of cases from year 1 clients' referrals or repeat business

Year 2 realistic targets: 80-150 completed cases, £80,000-£180,000 gross broker revenue. Profitability typically lands £40,000-£90,000 net for a solo broker working 40-45 hours/week.

Year 3 and beyond

By year 3, most brokers have decided whether to stay solo (lifestyle business, £100,000-£200,000 net), grow into a micro-firm with 1-3 additional advisers (£300,000-£800,000 firm revenue), or exit. The decision depends heavily on personality and goals — both paths are legitimate.

Brokers who grow into small firms typically hire a case administrator first (frees the principal broker to focus on new cases), then a para-broker, then a second fully-qualified broker. Each additional adviser adds roughly £80,000-£120,000 in marginal revenue at a 60-70% marginal profit once set up.

Client acquisition channels

The hardest part of building a mortgage broker business is consistent client acquisition. Five primary channels:

1. Estate agent and solicitor referrals (best long-term)

Typically 30-60% of established brokers' case volume. Requires active networking — aim for 2-5 new professional introductions per month. Pays off from month 6-12 onwards. Referral fees typically range from 0% (genuine reciprocal) to 20-30% of proc fee (paid referrer).

2. Existing client referrals (highest-quality)

Typically 10-25% of established brokers' volume. Requires deliberate asking — most brokers under-ask. A simple post-completion follow-up asking for referrals produces 0.3-0.8 referrals per satisfied client on average.

3. Buying leads (fastest but variable)

Purchased leads can provide volume quickly but require a solid follow-up process. See our how to buy mortgage leads UK guide and mortgage leads catalogue. Typically delivers 6-15 cases per month at £500-£2,500 budget depending on conversion.

4. Running own advertising

Google Ads, Facebook, Instagram. Requires 4-8 weeks of learning and £1,500+ of test spend to calibrate. Long-term cost per case is typically 30-50% cheaper than bought leads if done well, but most brokers don't have the time or technical knowledge to run ads well. See buying leads vs generating your own.

5. Content and SEO

Slow but compounding. Writing useful content, local SEO, and building a Google Business Profile can produce 3-10 new client enquiries per month by year 2-3. Very low marginal cost but 12-24 months to ramp. See our SEO for mortgage brokers guide.

Most successful brokers use a blend of 2-3 of these channels. Relying on one is risky — referral networks go quiet, advertising costs change, lead providers have variable quality weeks.

Critical risks to plan for

  1. Pipeline gap in year 1: Mortgage cases complete 2-4 months after first contact. A case acquired in month 3 completes in month 5-7. Plan cashflow for the gap between first enquiry and first proc fee payment.
  2. Income volatility: Even established brokers see 30-40% month-on-month revenue variation. Build a personal cash buffer of 3-6 months' living costs.
  3. Regulatory change: FCA consumer duty, changes to MCOB, and evolving Consumer Duty expectations mean higher compliance overhead than 5 years ago. Budget 5-8% of revenue on compliance annually.
  4. Lender criteria shifts: Specialist lenders come and go. Brokers reliant on one lender segment can see conversion drop significantly if that lender tightens criteria. Diversify your case mix.
  5. Key-person dependency: If you're a sole trader, your income stops if you can't work. Budget for income protection (£40-£120/month for a broker earning £60,000) and critical illness cover.

Next steps

If you're serious about building a mortgage broker business, prioritise three things in order: (1) CeMAP/equivalent qualification, (2) a network or DA authorisation route that doesn't crush your margins, and (3) a client acquisition plan you can sustain for 18 months. The technical side (CRM, sourcing, lender panels) is relatively easy once you have those three sorted.
