The verdict in three sentences
For a London SaaS scale-up that needs 10 landing pages per segment, buying pages one by one quickly costs more than a modular page system priced at 5,000 to 10,000 GBP. The real financial lever is conversion rate: moving from 1.5% on the homepage to 4 to 8% on a dedicated page cuts cost per lead by three to five times. Budget for A/B testing and HubSpot integration too, or your pages will generate contacts nobody qualifies.
What a B2B landing page costs in London in 2026
The London market is wide. A Webflow freelancer builds a page from a supplied design, a growth agency sells a package with copywriting, design, tracking and testing. The figures below are 2026 orders of magnitude based on agency and freelance quotes in Greater London, excluding VAT.
| Package | Price ex VAT 2026 | What is included | Timeline |
|---|---|---|---|
| Single page, design supplied | 700 to 1,000 GBP | Build, form, responsive | 1 week |
| Single page with copywriting | 1,300 to 2,200 GBP | Copy, design, GA4 tracking | 2 weeks |
| Modular system (15 to 20 blocks) | 5,000 to 10,000 GBP | Section library, usage guide | 3 to 6 weeks |
| 10 pages on an existing system | 2,500 to 5,000 GBP | Variants per segment | 2 to 3 weeks |
| A/B testing programme (3 months) | 1,300 to 3,500 GBP | Hypotheses, variants, analysis | 12 weeks |
| Advanced HubSpot integration | 900 to 2,500 GBP | Native forms, scoring, workflows | 1 to 2 weeks |
The logic is simple: beyond five pages, the modular system is cheaper per page. Ten pages at 1,800 GBP each cost 18,000 GBP. A system at 7,500 GBP plus 3,800 GBP of variants costs 11,300 GBP, and your marketing team can then build page eleven alone in half a day.
What a dedicated page earns compared with the homepage
LinkedIn and Google Ads are expensive in B2B. Sending that traffic to a homepage designed for every audience wastes a large share of the budget. A landing page per segment speaks to one problem and asks for one action.
| Metric | Homepage | Dedicated landing page | Gap |
|---|---|---|---|
| Visitor to lead conversion | 1.5% | 4 to 8% | x2.7 to x5.3 |
| LinkedIn Ads cost per click (London) | 6 to 12 GBP | 6 to 12 GBP | same |
| Cost per lead at 8 GBP per click | 533 GBP | 100 to 200 GBP | 2.7 to 5.3 times lower |
| Form fields | 6 to 9 | 3 to 5 | less friction |
| Target mobile load time | 3 to 4 s | under 2 s | better Quality Score |
| Message | Generic | Segment specific | relevance |
The number to remember: at 8 GBP per click, a 1.5% conversion rate produces a lead at 533 GBP, while 5% produces a lead at 160 GBP. On a media budget of 10,000 GBP per month, the gap is dozens of extra leads.
The technical points that make the difference
Three things separate a page that converts from a page that merely looks good. First, speed: a page under 2 seconds on mobile improves Google Ads Quality Score and lowers cost per click. Second, tracking: every form must push source, campaign and segment into HubSpot with clean UTM parameters. Third, testing method: a serious A/B test needs at least 300 to 500 conversions per variant, so test high impact elements first (headline, offer, form) rather than button colours.
On the legal side, UK GDPR and PECR apply: no pre-ticked marketing consent box, a clear purpose statement and a link to the privacy notice. A slip here invites ICO scrutiny and erodes trust with enterprise buyers.

Sophie, head of growth at an HR SaaS scale-up in London, spends 10,000 GBP per month on LinkedIn Ads at 8 GBP per click, about 1,250 clicks. On the homepage at 1.5%, she gets 19 leads, or 526 GBP per lead.
She orders a modular system at 7,500 GBP and 10 page variants at 3,800 GBP, plus 1,800 GBP of HubSpot work: 13,100 GBP in total. After two months of testing, her pages convert at 5%, giving 62 leads per month for the same media spend, at 161 GBP per lead.
Gain: 43 extra leads per month. If 8% become opportunities and 25% of those sign an annual contract worth 10,000 GBP, that is roughly one extra deal per month, or 10,000 GBP of annual recurring revenue. The 13,100 GBP investment pays back in under two months of new deals.
FAQ
How many landing pages does a B2B campaign need?
One page per segment and per offer is the rule. A vendor with 3 audiences and 3 offers quickly reaches 9 or 10 pages, which is why a modular system at 5,000 to 10,000 GBP makes sense.
Webflow, WordPress or Next.js for landing pages?
Webflow is fast to set up for an autonomous marketing team, WordPress fits if your main site already runs on it. Next.js delivers the best performance, often under 1.5 seconds, but needs a developer for structural changes.
What conversion rate should a B2B page target?
A goal of 4 to 8% for a demo request or white paper is realistic in 2026. Below 2%, fix the message or targeting before touching the design.
How long does a reliable A/B test take?
Plan 4 to 8 weeks depending on volume, with at least 300 conversions per variant. Below 1,000 visits per month, run sequential tests instead.
Should HubSpot be integrated from day one?
Yes, because a lead not followed up within 24 hours loses much of its value. Integration costs 900 to 2,500 GBP and enables automatic scoring from the first campaign.
