The verdict in three sentences
For a London firm running four funds and 35 portfolio companies, the website is first a deal sourcing tool for founders and owner-managers, then a trust tool for limited partners. A serious build in 2026 costs £35,000 to £65,000, plus £10,000 to £20,000 for a secure LP portal that handles quarterly reports. Plan 12 weeks, with two of them reserved for compliance review under the FCA financial promotion rules.
What each audience comes for
The founder of a £25 million revenue business reads your site very differently from a pension fund allocator. The founder wants to know whether you have backed a company like theirs, in their sector, with what cheque size and holding period. The LP looks for fund strategy, team, governance, ESG policy and clean access to documents. The site must serve both journeys without mixing messages, and it must never publish fund performance on open pages.
The core of the public site is a filterable portfolio: sector, region (London and South East, Midlands, North, Europe), deal type (buy-out, growth equity, secondary), entry year and status (current or realised). Each company page shows the logo, a founder quote, a three-line investment thesis and value creation milestones, with no multiples and no IRR.
| Site component | Audience | 2026 ballpark (ex VAT) | Watch-out |
|---|---|---|---|
| Bespoke design and digital identity | All | £9,000 to £16,000 | Restraint, typography, real team photos |
| Filterable portfolio of 35 companies | Founders | £6,000 to £11,000 | Written sign-off from each company |
| Fund, team, ESG and news pages | LPs and press | £6,000 to £11,000 | SFDR and UK SDR labels kept consistent |
| Insights hub and newsletter | Founders and advisers | £4,000 to £8,000 | Editorial calendar owned in-house |
| Legal notices, cookies, accessibility | Regulator | £3,000 to £6,000 | Past performance warnings |
| CMS, technical SEO, launch | Marketing team | £7,000 to £13,000 | Role-based editor permissions |
| Total public site | £35,000 to £65,000 |
The secure LP portal: scope and cost
Many mid-market firms still email quarterly reports as PDF attachments, with a real risk of sending them to the wrong person. A dedicated LP portal solves that: each investor sees only the funds they committed to, documents are timestamped and downloads are logged for audit.
| LP portal feature | Core version | Full version | Comment |
|---|---|---|---|
| Multi-factor authentication | Included | Included | Expected by institutional investors |
| Permissions by fund and investor | Yes | Yes, plus per document | Four funds, around 180 LPs |
| Quarterly report upload | Manual | Bulk import with notifications | 16 reports a year across four funds |
| Capital calls and distribution notices | No | Yes | Big win for fund operations |
| Access log and exports | Basic | Full, audit-ready | Useful for due diligence and audits |
| Indicative 2026 budget (ex VAT) | £10,000 | £20,000 | Excludes any third-party licence |
The alternative is an investor reporting SaaS, often priced between £10,000 and £30,000 a year depending on fund count. An integrated portal costs more in year one but much less over five years, provided you budget monthly maintenance of roughly £350 to £750 for security patches, updates and monitoring.
Compliance and the 12-week schedule
Any content that could be read as an invitation to invest must be approved and framed correctly. In practice: no IRR or multiples on public pages, a past performance warning wherever a figure appears, clear regulatory status and firm reference number in the footer, a cookie banner that follows ICO guidance and a privacy notice aligned with UK GDPR.
A typical schedule: weeks 1 and 2 for workshops and sitemap, weeks 3 to 5 for design, weeks 6 to 9 for build and loading the 35 company pages, weeks 10 and 11 for compliance review, week 12 for testing and launch. The item that most often delays launch is collecting approvals from portfolio companies.
Mini case study
Sarah, head of marketing at a London private equity firm, compares two five-year scenarios for 180 LPs.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
- Scenario A: site at £50,000 plus a third-party reporting platform at £18,000 a year. Five-year cost: 50,000 + 5 × 18,000 = £140,000.
- Scenario B: site at £50,000, integrated LP portal at £16,000, maintenance at £550 a month. Five-year cost: 50,000 + 16,000 + 60 × 550 = £99,000.
The gap is £41,000. Fund operations previously spent 3 days a quarter emailing reports; bulk import cuts that to half a day, saving about 10 working days a year. Scenario B wins, with a data portability clause in the contract.
FAQ
Can we show fund IRR on the public website?
It is not advisable: performance belongs inside the LP portal with the appropriate warnings. On public pages, use verifiable facts such as 35 portfolio companies or four funds under management.
How long does it take to publish 35 portfolio pages?
Budget around 2 hours of writing and approval per company, about 70 hours in total. Sign-off from portfolio CEOs is the bottleneck, so start the process in week 3.
Is a custom LP portal secure enough for institutions?
Yes, if it combines multi-factor authentication, document encryption, access logs and a penetration test before launch. A focused penetration test costs, as a 2026 ballpark, £4,000 to £8,000.
Do we need content in other languages?
If you raise from continental European or Middle Eastern LPs, a short translated section on strategy and team often helps. Budget £3,000 to £6,000 per language for reviewed financial translation.
What maintenance budget should we plan?
Roughly £350 to £750 a month depending on monitoring level and how often the LP portal is updated, so £4,200 to £9,000 a year.
