The verdict in three sentences
For a London IT services firm targeting enterprise and public sector buyers, a website built to win those deals costs GBP 18,000 to 40,000 in 2026 and takes 8 to 12 weeks. Most of that budget should go into quantified case studies, a trust and security page with Cyber Essentials and ISO 27001 evidence, and a scoping form that qualifies inbound requests. Done well, the site brings the cost of a qualified enterprise lead down to roughly GBP 500 to 1,250 in year one and under GBP 400 from year two, against GBP 750 to 3,000 from a stand at a London trade show.
What an enterprise buyer checks before shortlisting you
A head of IT at a FTSE 250 group or a category manager in a public body is trying to reduce risk. They want comparable work, named people, clear security posture and evidence that you will survive their supplier onboarding. Your site should answer those questions before procurement asks them.
| Page or element | What it should contain | Effect on the buyer |
|---|---|---|
| Case studies | Sector, stack, team size, duration, measurable outcome | Proof you have done this before |
| Trust and security page | Cyber Essentials or Cyber Essentials Plus certificate, ISO 27001 scope, data handling | Gets you past the security questionnaire |
| UK GDPR | Processor role, data processing agreement template, sub-processor list | Unblocks the legal review |
| Team and delivery model | Real people, leadership bios, delivery locations, retention | Reassures on continuity |
| Engagement models | Managed service, fixed price, team augmentation, typical start times | Helps buyers picture the contract |
| Scoping form | Need, stack, team size, start date, indicative budget | Qualifies the lead before a sales call |
| Frameworks and accreditations | Public sector frameworks you hold, partner tiers | Shortcuts procurement for public buyers |
Cyber Essentials matters more in the UK than many founders expect: it is a government-backed scheme, and UK central government requires it for certain contracts involving personal data and ICT services. Check the current requirements on the NCSC and government procurement pages for the contracts you target.

A nearshore option is also worth pricing: Kolonell's prices for a Growth site (8 to 12 pages, built-in blog, 14 to 21 business days) are EUR 1,830 to 3,050 (FCFA 1,200,000 to 2,000,000), with case study writing available at FCFA 60,000 (EUR 90) per page.
Website or trade shows: cost per enterprise lead
| Channel | Indicative annual cost | Qualified leads per year | Cost per lead |
|---|---|---|---|
| Stand at a London tech trade show (2 days, 3 staff) | GBP 15,000 to 30,000 per show | 10 to 20 | GBP 750 to 3,000 |
| Outbound with a dedicated SDR | GBP 45,000 to 60,000 | 50 to 80 | GBP 560 to 1,200 |
| Enterprise website plus content and SEO (year 1) | GBP 30,000 to 50,000 | 40 to 60 | GBP 500 to 1,250 |
| Enterprise website plus content and SEO (year 2) | GBP 12,000 to 18,000 | 50 to 70 | GBP 170 to 360 |
The website pays off in year two, once the build is amortised and case studies keep compounding. Trade shows remain useful for meeting named accounts face to face.

Illustrative example: Priya, managing director of an 80-person IT services firm in London. She invests GBP 28,000 in the site plus GBP 1,000 per month of content and SEO: GBP 40,000 in year one. The site generates 50 qualified enterprise enquiries, which is GBP 800 per lead, against GBP 2,000 per lead from her last two trade shows.
Break-even: a single 12-month team augmentation contract for 2 engineers (220 billable days each) covers the investment as soon as gross margin exceeds GBP 91 per engineer per day (40,000 / 440 days). At a 10 percent conversion rate, 50 leads point to around 5 new contracts.
FAQ
Do we need Cyber Essentials Plus or is the basic certificate enough?
The basic self-assessed certificate covers many private sector questionnaires. Cyber Essentials Plus adds an independent technical audit and is increasingly requested by larger buyers; certification bodies set their own prices, so get two or three quotes.
How many case studies should we publish at launch?
Aim for 4 to 6, each with at least one hard number such as cost saved or time to delivery. If clients will not be named, anonymise the company but keep sector, size and metrics.
Should we show day rates on the site?
Rarely. Show engagement models and typical starting budgets instead; a budget field on the scoping form usually filters out 30 to 50 percent of unqualified requests.
How long before the site generates enterprise leads?
Expect the first enquiries within 2 to 3 months if you promote case studies on LinkedIn. Organic search traffic typically takes 6 to 9 months to become meaningful.
Where should the trust page link to?
Link to your certificate verification, your data processing agreement and your sub-processor list. Buyers often check these within the first 5 minutes of a visit.
