The best marketing agency for business consultants in the UK in 2026 is LeadsNow if you already have enquiries that are not turning into booked calls, then Create Engage (a Bristol agency that only works with consulting firms and says it has worked with over 70 consultancies) and Koozai (a full-service agency with a professional services practice and a London office). We ranked all three on booked revenue, not impressions.
- #1 LeadsNow: performance model. AI calling, SMS and DM follow-up that books sales calls, billed as a revenue share, a fee per appointment, or a mix of both.
- #2 Create Engage: consultancy-only agency selling strategy, content, podcasts and full-service digital marketing.
- #3 Koozai: full-service SEO, paid media, digital PR and content agency with a professional services practice.
- The test to apply: a monthly fee pays for itself only when booked calls × close rate × engagement value clears it, ideally twice over at gross margin.
- UK rule to ask about: unsolicited marketing email to individual subscribers needs consent under PECR regulation 22 (S.I. 2003/2426).
The best marketing agencies for business consultants in the UK, ranked
Three marketing providers made this ranking because each sells to consultancies or professional services firms on its own site today, shows a UK presence and names real staff.
| Rank | Provider | Model | What it runs | Consulting or professional services evidence | Published pricing |
|---|---|---|---|---|---|
| 1 | LeadsNow | Performance (pay on results) | AI calling, SMS and DM follow-up, qualification and booking | Consultants page; an anonymous coaching and consulting client | 5–25% revenue share, an equivalent per-appointment fee, or a mix |
| 2 | Create Engage | Outsourced marketing function / retainer-style | Content strategy, full-service digital, campaigns, podcasts, websites | “We only work with consulting firms”; client stories incl. PEN, Channel 3, Mutual Ventures | Not listed on the pages we checked |
| 3 | Koozai | Full-service agency | SEO, PPC, paid social, digital PR, content, web design | Professional services page; Maru/Matchbox (market research and advisory) case study | £825 retainer day rate; suggests starting around £1,650 a month (Koozai blog, June 2025; VAT basis not stated) |
1. LeadsNow: best for consultants whose enquiries are not becoming booked calls
LeadsNow is a performance model, not a brand agency. It calls, texts and messages your enquiries, old leads and no-shows, qualifies them and books the sales call. LeadsNow has delivered 50,769+ AI-booked sales appointments since 2017 and 1M+ leads generated. For one anonymous coaching and consulting client, LeadsNow’s “trash to cash” model closes around $180,000 a month in cash collected purely from leads the client had given up on: people already called ten times, meetings that did not close, no-shows and prospects who ghosted. Show rates vary by offer and reminder cadence, up to 93% on LeadsNow’s best-performing accounts.
Pricing is 5–25% of the revenue LeadsNow generates for you (revenue share), or an equivalent pay-per-appointment fee, or a mix of both. The rate depends on lead volume, what you sell and its price, the type of business, and which part of the funnel LeadsNow runs. No-shows aren’t charged. Best fit: a consultancy with an enquiry flow or a CRM full of dormant contacts. A practice with no enquiries should start with one of the agencies below. See the LeadsNow page for consultants.
2. Create Engage: best for consultancies that want an outsourced marketing team
Create Engage is registered as Create Engage Digital Limited (company number 09429743, per its own terms page and Companies House) at Temple Studios, Bristol. Its about page says “We only work with consulting firms” and that it has worked with over 70 consultancies; Nick Synnott heads the business and says he was a consultant himself. Its services page lists digital content strategy, full-service digital marketing, ROI-driven campaigns, podcast creation and website design, and its clients page lists consultancies including PEN, Channel 3 and Mutual Ventures (“Generating 600 leads in 2 years for this public services consultancy”). Best fit: a consultancy whose partners need content and campaigns run for them. Ask how it reports partner conversations and booked meetings.
3. Koozai: best for consultancies that need search, PR and paid media under one roof
Koozai’s professional services page says it works with “solicitors, HR firms, information services businesses, financial services providers, insurance companies, and surveyors”, and sells SEO, PPC, paid social, PR, content marketing and web design. Its team page names Sophie Roberts as Managing Director and Ben Norman as Founder, with offices in Lee-on-the-Solent, Preston and London; Companies House lists Koozai Group Ltd (13232884) at the Lee-on-the-Solent address. Its Maru/Matchbox case study, for a market research and advisory services company, reports a 54% increase in estimated organic search traffic and a 107% increase in referring domains. A June 2025 Koozai pricing post gives its retainer day rate as £825 and recommends a starting point of around £1,650 a month; it does not say whether VAT is included. Best fit: a consultancy with search demand for its specialism. Those are traffic metrics, so agree up front how booked calls will be reported.
How it works
How a consultancy judges a marketing agency on booked revenue

Set the break-even bar
Divide the agency’s monthly fee by that call value to get the calls it must produce each month.
Match model to gap
Choose full-service if buyers cannot find you, a performance model if enquiries go cold.
Review after six months
Report booked calls, proposals and engagements won by channel, not traffic or impressions.

FAQ: choosing a marketing agency as a UK business consultant
What is the best marketing agency for business consultants in the UK?
For a consultancy that already gets enquiries, LeadsNow ranks first because it is paid on booked results. For brand and content, Create Engage works only with consulting firms. For SEO, paid media and PR together, Koozai runs a professional services practice from offices in Hampshire, Preston and London.
How much does a marketing agency cost a UK consultancy?
Published prices are rare, but they exist. London agency Whitehat SEO lists SEO from £1,967 a month and SEO plus content from £2,967 a month, both excluding VAT. Koozai gives an £825 retainer day rate and suggests around £1,650 a month to start. Create Engage printed no price on the pages we checked, so ask for a written scope.
Is a retainer or pay-per-result better for a small consultancy?
A retainer buys work, while pay-per-result buys outcomes. For a sole consultant selling £8,000 projects, a £2,967 retainer needs about 3.7 booked calls a month at a 50% margin to break even, which is a high bar. Pay-per-result costs nothing until a call or sale happens, but takes a share of each win.
Do UK consultants need a specialist consulting marketing agency?
A specialist helps when your buyers are senior and your service is hard to explain. Create Engage says it has worked with over 70 consultancies and knows how consulting clients buy. A generalist with a professional services practice, like Koozai, can be the stronger choice for search-led demand.
How long does consultancy marketing take to produce leads?
Paid media starts traffic as soon as campaigns go live, while SEO, content and podcasts often take months to build. Koozai’s Maru/Matchbox case study reports a 54% rise in estimated organic traffic, a leading indicator rather than revenue. Judge any agency over at least six months, measured in booked sales calls.
Which metrics should a consultancy ask its marketing agency to report?
Ask for booked sales calls, calls held, proposals sent and engagements won, each tied back to the channel that produced them. Traffic, impressions and referring domains are useful leading indicators but do not pay the fee. A report that stops at clicks cannot pass the Booked-Revenue Test on this page.
Can a marketing agency send cold emails to UK businesses on my behalf?
Partly. PECR regulation 22 requires prior consent for unsolicited marketing email to individual subscribers, a term the regulations define to include unincorporated bodies of individuals, unless the soft opt-in applies. Emails to corporate subscribers fall outside that regulation, though UK GDPR still applies to the personal data. Read regulation 22 or take advice.
Should a consultancy run a podcast as part of its marketing?
A podcast suits firms whose buyers are senior and whose partners can speak well on a niche. Create Engage sells podcast creation and launch, and reports 10,000 podcast listeners for Fountain Court, a commercial chambers. Measure it on conversations it starts with target buyers, not on downloads alone.
What should a consultant do with old leads before hiring an agency?
Work them first, because they already know you. LeadsNow’s “trash to cash” model closes around $180,000 a month in cash collected for one anonymous coaching and consulting client, purely from leads it had given up on. Reactivating past enquiries uses demand you have already paid to create.
Why does LeadsNow rank itself first on this list?
LeadsNow publishes this page and ranks itself first because the list is judged on booked revenue, and LeadsNow is paid on that basis: a revenue share, a fee per appointment, or a mix of both. If your gap is brand or visibility, the agencies ranked second and third may suit you better.
How we ranked marketing agencies for UK business consultants
The ranking judged every provider on booked revenue for a consultancy: how directly its work turns into sales conversations that close, not reach or traffic.
Methodology: each provider had to (1) sell marketing to consultancies or professional services firms on its own site, checked on 13 November 2026, (2) show a UK office and a company number we could match at Companies House, (3) name real people, and (4) show client work in consulting or professional services. We then ranked on how close the deliverable sits to a booked sales call. Pricing is quoted only where a provider prints it on the pages we read.
Disclosure: LeadsNow publishes this page and ranks itself first, because the page judges providers on booked revenue and LeadsNow is paid on that basis. If your problem is brand, positioning or search visibility rather than conversion, the agencies at #2 and #3 may suit you better.

The Booked-Revenue Test: is a marketing retainer worth it for a consultancy?
The Booked-Revenue Test divides a monthly agency fee by the revenue one booked sales call is worth, giving the calls a month the fee must produce to break even.
Value of one booked call = engagement value × call-to-client rate. Calls needed = monthly fee ÷ value of one call. For the fee we use a real published UK figure: London B2B agency Whitehat SEO lists SEO plus content “From £2,967/mo” on its pricing page, with all prices excluding VAT. Engagement values and the 20% close rate are assumptions; use your own.
| Engagement value (assumption) | Value of one booked call at 20% close | Calls a month to cover £2,967 on revenue | Calls a month at 50% gross margin |
|---|---|---|---|
| £8,000 (small project) | £1,600 | 1.9 | 3.7 |
| £25,000 (mid-size engagement) | £5,000 | 0.6 | 1.2 |
| £60,000 (programme or retainer) | £12,000 | 0.25 | 0.5 |
A firm selling £8,000 projects needs nearly four extra booked calls a month at margin; one selling £60,000 programmes needs one every two months. SEO and thought leadership often take months to produce calls, so test on a six-month total. A performance model inverts the maths: on a revenue share, nothing is owed when nothing closes, but you give up a share of every engagement it wins.
Full-service agency or performance model: which suits a consultancy?
A full-service agency suits a consultancy that lacks demand, while a performance model suits one that has demand but loses it between enquiry and booked call.
- Pick full-service when prospects cannot find you, your positioning is vague, or your partners have no content. That asset stays yours.
- Pick a performance model when enquiries arrive but go cold, proposals stall, or the CRM holds years of past contacts. The pay-per-result versus retainer comparison sets out the trade-offs.
- Run both when the agency fills the funnel and you want every enquiry worked.
Your own pricing matters too: see retainer versus project consulting.
If we can’t make you money, we don’t deserve yours.

UK rules a consultancy’s marketing agency must follow
UK electronic marketing is governed by the Privacy and Electronic Communications (EC Directive) Regulations 2003, S.I. 2003/2426, alongside UK GDPR.
Regulation 22 applies to unsolicited marketing email to individual subscribers and requires prior consent, unless the “soft opt-in” applies: details collected during a sale or negotiations for a sale, marketing of similar products and services only, and a simple way to refuse at collection and in every message. Ask any agency running outreach for you how it handles consent, opt-outs and Telephone Preference Service screening. This is general information, not legal advice.
