The verdict in three sentences
For a telecom services operator, merging 6 legacy websites into one corporate platform budgets at GBP 60,000 to 160,000 in 2026, with a realistic timeline of 6 months. Most of the value lies not in the design but in editorial governance: a headless CMS with a 3-level approval workflow stops an incorrect pricing announcement from going live. Finally, sizing for 200,000 visits a day during peaks (product launches, network outages, annual results) requires a CDN and a static architecture from day one.
What the unified platform costs in 2026
2026 orders of magnitude for a London-based operator, EN site with consumer, business, investor, press and careers areas.
| Item | Standard setup | Group setup |
|---|---|---|
| Audit of the 6 sites + content architecture | GBP 6,000 | GBP 12,000 |
| Design system and mock-ups | GBP 12,000 | GBP 26,000 |
| Front-end build (Next.js, static pages) | GBP 20,000 | GBP 48,000 |
| Headless CMS + 3-level workflow | GBP 10,000 | GBP 24,000 |
| Migration and 301 redirects (about 2,500 URLs) | GBP 6,000 | GBP 16,000 |
| WCAG 2.1 AA accessibility + security audit | GBP 6,000 | GBP 20,000 |
| Team training and acceptance testing | 0 (included) | GBP 14,000 |
| Total project | GBP 60,000 | GBP 160,000 |
The gap between the two columns comes mainly from the number of templates (25 versus 60), integrations (store locator, network coverage map, share price feed) and the level of audit required by the risk department.
Editorial governance: the 3-level approval workflow
In a telecom group, a pricing page involves marketing, legal and sometimes the regulator (Ofcom). The CMS must reflect that reality.
| Level | Role | Rights | Target approval time |
|---|---|---|---|
| 1. Author | Comms officer, HR, IR | Create, edit a draft | Immediate |
| 2. Business reviewer | Product manager, lawyer | Comment, send back, approve | 24 h |
| 3. Final approver | Head of communications | Publish, schedule, unpublish | 24 to 48 h |
| Emergency (network crisis) | Crisis unit | Logged direct publishing | 15 min |
| Archiving | Compliance | 5-year version history | Automatic |
This workflow is configured in a headless CMS such as Sanity or Strapi. Licence costs stay modest (GBP 0 to 6,000 a year depending on the number of editors), but configuring roles and audit logs takes 8 to 12 days of work.
Absorbing 200,000 visits a day without going down
| Component | Recommended choice | Estimated monthly cost |
|---|---|---|
| CDN with European points of presence | Cloudflare or Fastly | GBP 1,200 |
| Front-end hosting (static rendering + ISR) | Vercel or equivalent | GBP 600 to 1,400 |
| Headless CMS (enterprise plan) | Sanity, Strapi Cloud | GBP 0 to 500 |
| 24/7 monitoring and alerting | Uptime + logs | GBP 240 |
| Backups and recovery plan | Daily snapshot | GBP 160 |
| Total running costs | GBP 2,200 to 3,500 |
With 95% of pages served from cache, a peak of 200,000 visits a day (about 15 requests per second at the top) stays comfortable. The network status page, heavily visited during incidents, must be a static page regenerated every 60 seconds.
Mini case study

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
James, head of communications at a telecom services operator in London, currently runs 6 sites: corporate, consumer offers, business, foundation, careers and investor relations. Each site costs on average GBP 720 a month in hosting and maintenance, so GBP 4,320 a month, plus 2 different suppliers to manage. The unified platform at GBP 96,000 brings running costs down to GBP 2,800 a month: the saving of GBP 1,520 a month, or GBP 18,240 a year, already covers about 19% of the investment each year. On top of that, about 30 hours a month of editorial coordination are saved, with a single approval workflow for the whole group.
FAQ
Isn't six months too long for a corporate website?
For 6 sites to merge, it is a realistic timeline: 4 weeks of audit and architecture, 6 weeks of design, 10 weeks of development, 4 weeks of migration and testing. Squeezing it into 4 months is possible with a doubled team, which adds 20 to 30% to the budget.
Headless CMS or WordPress multisite?
A WordPress multisite costs 30 to 40% less to build, but a 3-level approval workflow and holding 200,000 visits a day require heavy plugins and caching. Headless separates publishing from delivery, which reduces the attack surface and outages.
How do we avoid losing the old sites' search rankings?
You need to map every indexed URL, often 2,000 to 3,000 for an operator, then set up 301 redirects one by one. Done properly, the migration keeps organic traffic loss under 10% for 4 to 8 weeks.
What compliance obligations apply in the UK?
UK GDPR and PECR require consent for analytics cookies and a record of processing activities, with ICO fines of up to GBP 17.5 million or 4% of turnover. Plan for a consent banner and a processing register, i.e. 3 to 5 days of work.
What does the GBP 2,200 to 3,500 monthly running budget cover?
The CDN (GBP 1,200), front-end hosting, CMS licence, monitoring and backups. Ongoing development (new pages, templates) is billed separately, usually GBP 1,600 to 4,800 a month.
