How Much Does a B2B or Software Marketing Agency Cost in the UK?

Specialist B2B and software marketing agencies usually cost more than generalist digital agencies, and for good reason: the audiences are smaller and more expensive to reach, the products take more explaining, and success is measured in pipeline and revenue rather than clicks. This guide sets out typical UK prices in 2026, what pushes a quote up or down, and what to look for when you choose an agency, in London or anywhere else.

Why B2B and Software Marketing Costs More

• Long, complex sales: buying decisions involve several people over weeks or months, so campaigns have to reach and persuade a whole buying group.
• Small, expensive audiences: reaching a few thousand decision makers on LinkedIn costs far more per click than consumer advertising.
• Technical subject matter: credible content needs time with your product and engineering people, not just a copywriter.
• Measurement: tying marketing to pipeline means working inside your CRM, typically HubSpot or Salesforce, and agreeing definitions with your sales team.

Typical UK Prices in 2026

As a rough guide to what specialist B2B and SaaS agencies charge:

• Multi-channel retainer (strategy plus two or three channels): £3,000–£12,000/month
• B2B SEO and content: £1,500–£6,000/month, depending mainly on content volume
• LinkedIn and Google Ads management: £800–£3,000/month plus ad spend
• Account-based marketing programmes: £5,000–£15,000/month
• Positioning and messaging project: £3,000–£15,000 one-off
• B2B or SaaS website: £8,000–£40,000, more with complex integrations
• Fractional marketing leadership: £600–£1,200 a day, usually a few days a month

Generalist agencies may quote less for similar-sounding work. The question is whether they can produce content your buyers find credible and show its effect on pipeline. For wider benchmarks, see our digital marketing agency pricing guide.

What Drives the Price

• Channels and content volume: how many channels, and how many articles, reports or videos a month, account for most of the difference between quotes.
• Who writes: content by specialists who interview your team costs more than generalist copy, and is usually worth it.
• Markets: campaigns across several countries or languages add cost.
• Seniority: strategy-led agencies with senior people on the account charge more than delivery-focused ones.
• Location: regional agencies are typically 20–40% cheaper than London ones for comparable seniority.

Pricing Models

Most B2B agencies work on monthly retainers, with projects for one-off pieces such as positioning or a new website. Some offer pay-per-lead or pipeline-based pricing. Be careful with fees tied to lead volume: they reward quantity, and the cheapest leads to generate are rarely the ones your sales team wants. If you agree any performance element, tie it to qualified opportunities or revenue, with the definitions written into the contract.

Choosing a Software Marketing Agency in London

London has the UK's deepest pool of SaaS and B2B specialists, and also its highest rates. Wherever you buy, these questions separate genuine specialists from generalists with a B2B page on their website:

• Do they speak your metrics? A good software marketing agency talks about pipeline, customer acquisition cost and payback, trial-to-paid conversion and churn, not just traffic and leads.
• Is their experience the right shape? Marketing a self-serve product to small businesses is very different from supporting an enterprise sales team. Ask for case studies with a similar deal size and sales process.
• How will they learn your product? Ask who writes the content and how they will get time with your product and engineering people.
• How will results reach your CRM? Agree lead definitions, attribution and reporting before any campaign starts. Our guide to measuring marketing ROI covers the basics.
• Who is on the account? In London especially, senior people win pitches and more junior staff can end up doing the work. Name the team in the contract.

Our London buyer's guide explains how to avoid overpaying in the capital, and you can compare London agencies directly. Strong B2B and technology agencies also work out of Manchester, Cambridge and Bristol, usually at lower rates.

Agency, In-House or Both?

Many B2B and software companies combine an in-house marketer, who owns the strategy and knows the product, with an agency for specialist execution such as paid media, SEO or content production. Our comparison of in-house teams and agencies sets out the real costs of each, and a clear marketing brief will get you quotes you can actually compare.
