Which UK lead generation agency is best?
The best lead generation agencies in the UK for 2026 are Gripped for B2B SaaS demand generation, Lead Gen Dept for senior-led calling, Fifty Five and Five for enterprise tech and Add People for small-business PPC. Belkins adds finance outbound from the US. Across the 13 agencies we track, the median minimum is $2,250 a month, with 50% in the budget tier. UltraGrowthMedia is the pick for teams that want outbound-led lead generation with SEO in the same team.
Key takeaways
- The best lead generation agencies in the UK range from a productised £89-a-month entry offer at Add People to retainers of $7,500 to $25,000 a month at B2B specialists such as Gripped.
- 6 of the 13 agencies are headquartered in the UK: Gripped, Lead Gen Dept, Fifty Five and Five and Growth Division in London, Add People near Manchester, and a London video studio we did not rank. The other picks work with UK clients remotely.
- UK buyers face UK GDPR and PECR on outbound email and calls. PECR treats corporate and individual subscribers differently, so ask how an agency segments contacts before it sends anything.
- UK agencies in this pool have a median minimum of $6,250 a month against $1,000 for North American ones, so local does not mean cheaper, while time-zone overlap is the main trade-off for remote picks.
- Agencies in this directory mostly quote in US dollars, apart from Add People's sterling pricing, so budget for exchange-rate movement on any USD retainer.

The 12 best lead generation agencies in the UK in 2026
Each agency below leads a specific category. Start with the one that matches your situation rather than reading top to bottom.
#1Best overall for UK B2B SaaS growth
Gripped
Full-service B2B SaaS growth agency covering demand, ABM, SEO, and paid
Gripped was set up in London in 2017 by two marketers who came from inside B2B software, and about 25 people now work from Southwark. It combines demand generation, ABM, SEO and paid, with LinkedIn Ads as a standout skill, and concentrates on SaaS, cybersecurity, fintech, HR tech and dev tools. It holds a 4.8 rating, and its London base helps UK and EU buyers.
Watch out
Retainers start around $7,500 a month, and it publishes no marquee client roster to check against.
#2Best for senior-led calling and meetings
Lead Gen Dept
UK outbound sales agency booking meetings through senior cold calling with email support
Lead Gen Dept is a London agency, trading name of Gravitasio Ltd, that books meetings through senior salespeople rather than junior callers, according to the agency, with email in support. It targets high-value deals and lists IT and software, financial services and manufacturing clients. It offers a one-month trial with no service fee if unhappy, holds 4.9 across 27 Clutch reviews and sets a $5,000 minimum.
Notable clients
- Parker Software
- Ground Support Labs
- Sweep
- Pervasive Displays
- Crescat Digital
- WebMotion
Watch out
Calling is the lead channel, and one 2.5-star review reported fewer qualified meetings than the lead guarantee promised.
#3Best for startups wanting outbound plus SEO
UltraGrowthMedia
Full-stack marketing for ambitious growth-stage brands.
UltraGrowthMedia generates B2B pipeline from cold email, LinkedIn outreach and in-house lead research, with SEO, content and GEO available when you want inbound demand as well. Each programme starts with ICP definition, verified lead lists and properly set-up sending domains. The agency says it typically targets 10 to 20 qualified meetings a month from email and 15 or more from LinkedIn, and one client reports a 60% drop in cost per lead within 90 days. Founded in 2022 by Tushar Dey, the 27-person remote team works in weekly sprints, clients talk directly to the practitioners doing the work, and progress shows up on live reporting dashboards. Retainers start at $3,500 a month.
Watch out
A small team limits capacity, and there is no UK office for in-person sessions.
Run by our team.
#4Best for enterprise tech campaigns
Fifty Five and Five
London B2B tech marketing agency building AI-powered campaigns and sales tools
Fifty Five and Five is an independent B2B agency in Bermondsey, south-east London, incorporated in 2011 and still led by its founder. Its clients include Microsoft, SAP, Google, Tata Consultancy Services and Algolia, and it won Bronze at The Drum Awards for B2B 2025 for an AI-driven TCS campaign. It also builds custom AI tools for marketing and sales teams.
Notable clients
- Microsoft
- SAP
- Tata Consultancy Services (TCS)
- Algolia
Watch out
It focuses narrowly on B2B tech, publishes no review score or pricing, and is a poor fit for local or consumer businesses.
#5Best for small businesses and lead-gen PPC
Add People
Large Greater Manchester agency selling SEO, PPC and AI tools to small businesses
Add People began in 2002 and is one of the larger independent agencies in the north of England, with more than 250 staff in Altrincham. It sells lead generation PPC, SEO and ecommerce campaigns to SMEs, with productised offers from £89 a month. It is a Google Premier Partner, ranked 12th in Prolific North's Top 150 for 2026, and reports over 2,000 five-star Trustpilot reviews.
Notable clients
- Door Supplies Online
Watch out
A high-volume SME model means less bespoke strategy, and SEO and PPC pricing is not published.
#6Best for startup channel testing
Growth Division
London growth marketing agency that tests channels for startups using freelance specialists and AI
Growth Division is a London agency for startups and scale-ups, led by a fractional growth strategist who runs structured channel tests across paid, content, email and LinkedIn outreach. Clutch lists two to nine staff, with specialists on freelance contracts. Reviewers praise its communication and delivery, and it holds 4.7 across 31 reviews. Clients include Libeo and Weavr, with a $10,000 minimum and a $50 to $99 hourly band.
Notable clients
- Tytl
- ThatRound
- Eat Sleep Cycle
- Libeo
- Weavr
- Breezy
Watch out
Each channel is costed separately, so reviewers found budgeting hard, and a few wanted bolder experiments sooner.
#7Best for finance and fintech outbound
Belkins
Outbound appointment setting for B2B firms, with a dedicated finance and consulting offer
Belkins has 234 Clutch reviews averaging 4.9, the largest review base on this page, and runs cold email, LinkedIn and calling together for B2B firms. It has dedicated finance and consulting offers with named fintech clients, and owns its deliverability tools. The finance starter package is priced from $5,000 a month. It is based in Denver, Colorado and works with UK clients remotely, so calls fall in the UK afternoon.
Notable clients
- Mona
- Lisnr
- Token
- GroupFund
- Ordway
- Lunupay
Watch out
The $5,000 starter price is steep for small professional firms, and a few reviewers reported leads that missed their criteria.
#8Best for managed cold email infrastructure
SalesAR
Outbound lead generation and appointment setting with managed cold email infrastructure
SalesAR runs appointment setting through managed cold email and LinkedIn outreach, including sending infrastructure and deliverability support. It has 136 Clutch reviews at 4.9 with Premier Verified status, a $1,000+ minimum and published case studies showing contacts, replies and appointments. It is registered in Dover, Delaware, with offices in London and Kyiv, and works with UK clients remotely. That London office gives it a UK reference point.
Notable clients
- Akridata
- Foxit
- WEYTEC
- AwardWallet
- Bulu
- Poyant
Watch out
No prices are published, and one recent Clutch reviewer reported zero leads and low-quality outreach.
#9Best for multichannel SDR on a low minimum
Leadium
Outbound appointment setting for B2B teams via email, calls and LinkedIn
Leadium is a done-for-you SDR team running email, phone, LinkedIn and sales gifting, with data and deliverability handled in one engagement. It holds 5.0 across 90 Clutch reviews, with starting budgets from $1,000 and clients such as Segment, Veem and People.ai. It is based in Las Vegas, Nevada and works with UK clients remotely, so overlap is limited to the UK afternoon.
Notable clients
- Segment
- OpenEdge
- SignalWire
- Phunware
- Bottomline
- Veem
Watch out
Reviewers mention a slow initial ramp-up, and some site figures are inconsistent, so ask for current references.
#10Best for outsourced SDR teams at scale
Martal Group
Outsourced B2B lead generation and appointment setting across calls, email and LinkedIn
Martal Group, founded in 2009, runs calling, email and LinkedIn as one sequence through dedicated teams with weekly syncs, according to reviewers, who say it favours lead fit over volume. It has 109 Clutch reviews averaging 4.8 and lists medical, telecoms, manufacturing and IT among its sectors. It is based in Oakville, Canada and works with UK clients remotely, with Canadian hours overlapping the UK afternoon.
Notable clients
- Awin
- Blaze AI
- US Cloud
- ICUC Social
- Wrk
- Lease a Bike
Watch out
Clutch typical projects start at $10,000, and one reviewer found the cost unsustainable against results.
#11Best for CRM-linked reporting at scale
WebFX
Full-service digital with a 500-person team and a proprietary RevenueCloudFX platform.
WebFX is a Harrisburg, Pennsylvania agency with more than 750 staff, a 4.9 rating and close to 30 years of operation, and it serves UK buyers remotely. Lead generation is a listed service, and its RevenueCloudFX platform connects campaign activity to CRM data. Minimums start around $2,500 a month, with an hourly band of $100 to $149.
Watch out
It is US-based, smaller accounts can end up with junior pods, and the platform adds some vendor lock-in.
#12Best remote pick for SaaS scale-ups
Powered by Search
Demand generation and SEO agency built for B2B SaaS scale-ups
Powered by Search is a Toronto agency that began in 2009 and works with UK software companies remotely. It reports serving more than 200 B2B firms, lists Elastic, SentinelOne and Varonis as clients, and runs SEO, paid, ABM, GEO and HubSpot RevOps together.

How to choose a UK lead generation agency
- Decide what a lead means to youSettle whether you want booked meetings, form fills or sales-qualified opportunities, and write the definition down before approaching agencies.
- Choose between sector depth and SME volumeSpecialists such as Gripped suit software buyers, while large SME shops suit local services. The two models price and report very differently.
- Check overlap with UK hoursLondon-based agencies work your day. Agencies in Toronto, Pennsylvania, Colorado or Nevada need agreed call windows, and Sydney leaves a narrow window.
- Ask about UK GDPR and PECRRequest a plain explanation of lawful basis, how corporate and individual subscribers are treated, and how unsubscribes are honoured.
- Compare quotes in one currencyAsk whether fees are in sterling or dollars, whether VAT applies, and what happens to the price if exchange rates move.
- Protect your data and accountsMake sure your CRM, ad accounts and prospect lists stay under your ownership, with a notice period you can live with.
Questions to ask
- Which UK or EU clients can you show us, and what changed in their pipeline within six months?
- How do you source contact data, and how do you comply with UK GDPR and PECR?
- Which of your team will work UK hours on our account?
- Are your fees in pounds or dollars, and is VAT quoted separately?
- How do you separate leads that are marketing-qualified from ones sales will actually call?
- Which reports can we see weekly, and do they reach as far as closed revenue?
Red flags
- Promises of guaranteed meetings with no definition of a qualified one.
- Bought contact lists with no explanation of lawful basis under UK GDPR.
- Sterling-looking prices that turn into dollar invoices after signing.
- Cheap packaged plans that cannot name who runs your campaigns.
- Reports that show opens and clicks but never reach opportunities.
UK lead generation agency vs freelancer vs in-house
| Specialist agency | Freelancer | In-house team | |
|---|---|---|---|
| Typical cost | £89 productised plans to $25,000+/mo | Day rate or project fee; usually lower | Salaries, data, tools and ad budget |
| Skills covered | Outbound, paid, content and reporting | One or two channels | Depends on hires; often one generalist |
| Speed to start | 2 to 4 weeks | Days | 2 to 4 months to hire |
| Best for | Multi-channel pipeline programmes | Defined campaigns and small budgets | Steady, high-volume demand |
| Main risk | Templated campaigns on small accounts | Capacity and continuity | Hiring cost and single-person dependence |
What does a UK lead generation agency do?
A UK lead generation agency is a company that brings qualified prospects into a British business's sales pipeline. It combines outbound email and LinkedIn outreach, paid search and social, SEO and landing pages, then hands leads to sales with reporting. UK providers also have to work within UK GDPR and PECR, which govern how contacts are sourced and messaged, so compliance habits matter as much as campaign skill.
UK lead generation agency FAQ
What is the best lead generation agency in the UK?
No single agency fits every UK buyer. Gripped is our top pick for B2B SaaS, Lead Gen Dept suits senior-led calling, Add People suits small businesses wanting PPC lead generation, and Fifty Five and Five suits enterprise tech marketing. The right choice depends on your sector, deal size and budget, so compare two or three on evidence.
How much does a lead generation agency cost in the UK?
UK lead generation agencies range from productised plans from £89 a month at the SME end to retainers of $7,500 to $25,000 a month for B2B specialists. Across the 13 agencies we track the median minimum is $2,250 a month, and 50% sit in the budget tier. The sample is small.
Is cold email allowed for UK lead generation?
Cold email to businesses in the UK is regulated by PECR alongside UK GDPR. PECR treats corporate subscribers differently from individuals such as sole traders, and every message needs a clear way to opt out. Ask an agency how it segments contacts and records consent, and take legal advice for your own case.
How long does a UK lead generation agency take to get results?
Paid and outbound campaigns usually produce first replies or enquiries within four to six weeks, while sales-ready pipeline tends to take three to six months. SEO-led lead generation is slower, often six to twelve months. Ask for a 90-day plan with milestones so you can judge progress early.
Should I hire a UK-based or a remote lead generation agency?
Hire UK-based if you want working-day overlap and in-person workshops, as with Gripped or Lead Gen Dept in London or Add People near Manchester. Remote agencies from Canada, the US, Australia or India can offer niche skills but need agreed call windows. Six of the 13 agencies we track are UK-headquartered.
Do UK lead generation agencies quote in pounds?
Some do, but not all. Add People publishes sterling pricing, while most agencies in our directory quote in US dollars, including those based in London. Ask each agency to state the currency in writing, confirm whether VAT is extra, and check what happens if exchange rates move during your term.
How do I choose a lead generation agency in the UK?
Start with the lead definition, then match agency type to your market: sector specialists for B2B software, large SME shops for local services. Check reviews, ask for references from UK clients, and confirm how they handle UK GDPR and PECR. Compare reporting samples that reach opportunities and revenue.
Are lead generation agencies worth it for UK SMEs?
They are worth it when you can close the leads you already get and need more volume. UK SMEs often start with productised PPC plans or mid-market retainers of $1,000 to $5,000 a month, which cover 30% of the agencies we track. They rarely pay back before your offer and follow-up are proven.
