What does a B2B marketing agency do?

A B2B marketing agency helps business-to-business companies generate qualified pipeline through positioning, brand, website, content, and demand generation. Potent works as a strategy-led partner — not a vendor — building the brand and the revenue engine that sits behind it.

What makes Potent different from other B2B marketing agencies in the UK?

Potent leads with strategy and commercial outcomes, not deliverables. Every brand, website and campaign is reverse-engineered from buyer behaviour and revenue targets. Our work spans brand strategy, identity, website builds, fractional CMO support and ongoing marketing retainers.

How much does a B2B marketing agency cost in the UK?

UK B2B marketing agency engagements typically range from £5k for one-off Brand MOTs to £8k–£20k per month for ongoing strategic retainers. Full brand and website builds usually sit between £25k and £80k depending on scope. Potent publishes pricing context up front so there are no surprises.

Do you work with companies outside the UK?

Yes. Potent is UK-based but works with B2B brands across the UK, EU and US — particularly in tech, recruitment, professional services and industrial sectors.

Marketing Budget Calculator

'How much should we spend on marketing?' is the wrong question. The right question is: 'What's the cost of acquiring a customer, what's their lifetime value, and how many do we need?'

But since everyone asks it, here's a framework that actually works.

The Revenue Baseline

Most B2B businesses should invest 5-12% of revenue in marketing. The exact number depends on growth stage:

Pre-revenue to £500K: 15-20% of target revenue. You're investing in building the engine. This feels expensive because it is — you're front-loading spend before the flywheel kicks in.
£500K - £2M: 10-15%. You've proven product-market fit. Now you're scaling acquisition. This is where most companies under-invest and stall.
£2M - £10M: 7-12%. The engine is running. You're optimising channels and adding capacity.
£10M+: 5-8%. You should be running a sophisticated, multi-channel operation with clear attribution.

Channel Allocation

For B2B companies under £5M revenue, the highest-ROI allocation is typically: 40% brand and content (website, content creation, design), 25% demand generation (LinkedIn, email, paid), 20% events and partnerships, 15% tools and technology.

Above £5M, shift 10% from content to paid channels and add ABM.

The CAC/LTV Equation

If you don't know these numbers, stop here and calculate them. Customer Acquisition Cost = total marketing + sales spend ÷ new customers acquired. Lifetime Value = average deal value × average customer lifespan × gross margin. Your LTV should be at least 3x your CAC. Under 3x? Your unit economics don't work.

The Spend Trap

The biggest mistake isn't underspending — it's spending on the wrong things. £50K on Google Ads with no conversion-optimised landing page is a waste. £50K on a beautiful website with no traffic strategy is a waste. Spend on the constraints, not the vanity projects.
