B2B lead generation · UK

The B2B lead generation agency that sources signed contracts

One B2B contract beats a hundred domestic jobs. GrowthLine specialises in B2B contract sourcing — we turn Google Ads into signed commercial contracts for UK service businesses, not just leads. Reliable contracts compound: steadier cashflow, income a lender will count because it is contracted, and the track record that grows an SME to the point it can compete for the bigger formal tenders.

The economics: fewer leads, bigger outcomes

Start with an honest irony. In the UK, "b2b lead generation" is searched around 1,000 times a month at an average cost per click of £99.44, "b2b lead generation agency" 260 times at £120.89, and "b2b lead generation companies" 320 times at £16.51 — UK Google Ads data (DataForSEO), July 2026. Clicks in our own category cost £100 or more, which is exactly why this page earns its traffic instead of buying it.

Now look at the sectors where we actually run ads. The clicks that win commercial contracts cost a fraction of that — often no more than their domestic equivalents:

Sector Monthly B2B searches Avg CPC
Fleet & HGV services ~30,000 £3.67
Commercial electrical 5,230 £6.38
Commercial cleaning 3,560 £7.26
Fire safety 2,500 £9.70
Grounds maintenance 2,400 £4.07
Office fit-out 2,360 £22.30
Scaffolding 2,180 £6.78
Steel fabrication 1,590 £9.47

UK Google Ads data (DataForSEO), July 2026 — monthly UK search volumes across each sector's B2B terms and average cost per click.

The argument in one comparison: a commercial electrical click costs £6.38 while "electrician near me" costs £6.46. Same click price, a contract-size customer — the searcher on the B2B term is specifying work for a building, a site or a fleet, not a fuse box. The lead volume is smaller; what each lead can become is not comparable.

Who's searching

The people behind those searches are busy, not loyal. They have a problem to solve this week, a boss to answer to, and no patience for a supplier who makes them work for a quote. They give the contract to whoever makes their job easiest.

Procurement managers

Need compliant quotes on the desk by Friday. They search for the specific item or service, want a price against a spec without a phone tag marathon, and remember the supplier who turned it round same-day.

Manufacturing managers

A supplier has let them down mid-run, or capacity is full and work needs sub-contracting now. They search for exactly the process they need — and the firm that can take a drawing today wins the overflow, then the schedule.

Project managers

Pricing a package on a live programme. They have drawings and a deadline; what they do not have is time to write a brief. A page that accepts the drawings and answers in hours beats a better firm that answers on Thursday.

Facilities managers

Buy cleaning, grounds, fire safety and maintenance as recurring service contracts. They want one reliable supplier per problem and a painless renewal — which is why one won contract so often becomes years of revenue.

How we win contracts

The method is friction removal. At every point where a commercial buyer could give up and click the next result, we take the work out of their hands.

  1. The search

    Buyers search for a specific solution — "sub-contract steel fabrication", "commercial cleaning contract", "fleet servicing" — not for a supplier's brand. We run tightly matched ads against those exact solution searches, sector by sector, nationally across the UK.

    input: real UK search-term data per sector

  2. The dedicated page

    Each specific solution gets its own landing page — not a generic "we do X" site — with drawing, plan and spec upload built in, so the buyer never has to write a brief. They attach what they already have and press send.

    one page per solution · spec upload standard

  3. The fast response

    Enquiries arrive as emails, drawing submissions and phone calls, and get answered in hours — because the buyer who hears back first usually stops looking. Clients typically close 30–50% of B2B enquiries into qualified work (client-reported).

Sectors we source contracts in

Each sector has its own page with its own market data, buyer personas and the method applied concretely:

Sell to consumers rather than businesses? That is a different discipline with different economics — see B2C lead generation.

Proof: the steel fabricator

DRST Trading, a steel fabrication firm serving Bedfordshire and North London, came to us with no website and one customer. Within the first 30 days of ads going live:

£120k/mo

Recurring contracted work won within the first 30 days

Client-reported, DRST Trading

£80k/mo

Largest single contract — confirmed in month one as an ongoing annual deal

Client-reported, DRST Trading

~£42

Cost per enquiry, on £1,700/month of ad spend

Client Google Ads account

Alongside the headline contract came a steady run of B2B jobs at £3k–£20k each. Read the full case study

The same playbook runs in other sectors. A DPF-cleaning specialist we work with cut cost per lead from £86.50 to around £19.97 at £10k/month of spend — roughly 400 consumer leads a month — and is now layering in HGV and fleet B2B contracts specifically because contracted revenue is bankable: it smooths cashflow and lets the firm raise credit to expand faster than one-off jobs could fund. That case study is here, and the rest are on the results page.

What we won't promise

Google Ads wins medium-size, recurring commercial contracts. The multi-million contracts go through formal tendering — frameworks, PQQs, procurement portals — and no ad campaign shortcuts that. What the ads-won contracts do is build the cashflow and the track record that get an SME to that table: contracted revenue you can plan and borrow against, delivered work you can point to in a PQQ. That is the ladder, and we will never pretend the first rung is the top one.

Nor will we promise a timeline. Depending on the industry, the first contract can land in a week or take months — buying cycles, sign-off chains and contract values differ too much for one honest number. Tell us your sector and we'll give you the honest picture before any money is spent. Engagements are custom and deal-dependent — B2B work starts at £1,000 a month, with the details on the pricing page.

A note on LinkedIn

We run selective LinkedIn campaigns in certain niches, where the buyer genuinely lives there. But costs are higher and sales cycles longer, so for most clients it is a later expansion — added once search is compounding, not before. Google Ads plus dedicated landing pages is the engine; LinkedIn is a gear you add when the engine is already running.

B2B lead generation: FAQs

What does a B2B lead generation agency do?

A B2B lead generation agency produces enquiries from other businesses — usually through some mix of cold outreach, bought data lists and paid media. GrowthLine's version is narrower and goes further: B2B contract sourcing. We run Google Ads against the searches commercial buyers actually make, build a dedicated landing page for each specific solution — with drawing and spec upload so the buyer never has to write a brief — and the enquiries arrive as emails, drawing submissions and phone calls. The measure of success is not a list of contacts; it is signed, recurring commercial contracts.

Can Google Ads really win commercial contracts?

Yes — with the size of the win stated honestly. DRST Trading, a Bedfordshire steel fabricator, went from no website and one customer to around £120,000 a month of recurring contracted work within the first 30 days of ads going live, the largest single contract worth £80,000 a month and confirmed in month one as an ongoing annual deal (client-reported; the full numbers are in the case study). It works because commercial buyers — procurement, manufacturing, project and facilities managers — search for a specific solution and give the work to whoever makes their job easiest. What Google Ads does not win is the multi-million contract, which goes through formal tendering.

What size contracts can we expect?

Medium-size, recurring commercial contracts — supply agreements, service contracts and sub-contract packages, typically alongside one-off B2B jobs in the thousands. At DRST that meant B2B jobs of £3,000–£20,000 plus a recurring contract worth £80,000 a month; your sector's range will differ, and we will not guarantee a figure. The multi-million contracts go through frameworks, PQQs and formal tendering — Google Ads does not shortcut that. What the ads-won contracts do is build the contracted, bankable revenue and the track record that get an SME to that table.

How long until the first contract?

Anywhere from a week to a few months, and the honest answer depends on the sector: how often buyers go to market, how long their sign-off takes, and the value of the contract. DRST signed its largest contract within the first month; a sector with annual renewal cycles moves slower. Once the enquiries arrive, clients typically close 30–50% of them into qualified work (client-reported, not a guarantee). Tell us your sector and we'll give you the honest picture before any money is spent.
