The financial-reality companion to our guide to starting a UK letting agency and our 27-item setup checklist.
Realistic 12-Month Budget
You can launch a UK letting agency for under £3,000 in year-one fixed costs if you're disciplined. You can also spend £25,000 if you set up a high-street branch with staff. We'll lay out three realistic budgets — lean (solo-founder, home-based), standard (small office, ~30 properties target), and scaling (high-street branch, 2 staff).
One-Off Setup Costs
These are paid once at startup, not annually.

| Companies House registration | £12 | £12 | £12 |
| Logo + brand identity | £50 (Fiverr/Canva) | £500 (freelance) | £2,000 (agency) |
| Website | £0 (built-in with software) | £800 (Webflow + freelance) | £3,500 (custom) |
| Office fit-out | £0 (home-based) | £0 (co-working) | £8,000 (high-street unit) |
| Office equipment / phones | £300 (laptop) | £1,500 (laptops + phones) | £4,000 (desks + phones + IT) |
| Legal templates (AST, letting agreement) | £0 (included with software) | £0 (included with software) | £500 (bespoke lawyer) |
| One-off total | £362 | £2,812 | £18,012 |

Combined Year-One Total
| Budget tier | Year-one total |
|---|---|
| Lean (solo, home-based) | ~£12,400 |
| Standard (co-working, no staff) | ~£27,200 |
| Scaling (high-street, 2 staff) | ~£143,000 |
Break-Even Property Count
Roughly speaking, a Fully Managed property at the UK average rent (~£1,400/mo) generates ~£140/mo in management fee + ~£100 in Tenant Find revenue amortised. So each managed property delivers ~£1,500/year of revenue.
For each tier, that gives a rough break-even property count:
- Lean — break even at ~9 properties under management.
- Standard — break even at ~20 properties.
- Scaling — break even at ~95 properties (these agencies usually open after acquiring an existing book).
Realistic timeline to get there is 6–18 months of dedicated marketing for tiers 1 and 2, longer for tier 3 (which is why most agencies start lean and only scale once revenue justifies it).
Where New Agencies Save Money Sensibly
- Skip the office for the first year. Meet landlords at their properties or at a coffee shop. Save £3,600–£18,000.
- Pick one CRM that does everything. The biggest hidden cost is buying separate tools and paying integration consultants to make them talk. Our software comparison walks through the trade-offs.
- Negotiate Rightmove pricing. Their list prices are aggressive but new-agency discounts of 20–40% are common — ask.
- Defer the £79/month AI receptionist until your phone is ringing enough to need it. But not too long — the moment you miss your first lead because you were viewing a property is the moment Nita pays for herself.
Where Not to Cut Costs
- Don't skip insurance. One uninsured claim wipes out years of profit.
- Don't skimp on compliance. A missed gas safety certificate or AML check exposes you to £20k–£30k+ fines and prison.
- Don't try to handle deposits without scheme protection. 1–3× deposit penalty + can't evict via Section 21 (oh wait, that's gone — see our Section 21 abolition guide).
Ready to Sketch Your Budget?
Most new agencies launch on the Lean tier. The software cost (£399/month) is the biggest line item — and it's the one that lets you stay solo for the longest. Book a demo and we'll walk through how LettingGuru's pricing scales as you grow. Or read the related pieces:
