The verdict in three sentences
Switching agencies without rebuilding is possible and often 3-4 times cheaper than a full rebuild. The real obstacle is not technical but contractual: retrieving access, code and domain from an uncooperative outgoing agency. A handover audit at 800-2,500 EUR lets you decide, fully informed, between takeover and rebuild.
Takeover vs rebuild: the 2026 comparison
2026 order of magnitude on the Toronto market (EUR), for an existing 10-to-20-page B2B marketing site.
| Line item | Takeover | Full rebuild |
|---|---|---|
| Initial audit | 800 – 2,500 EUR | included |
| Remediation / fixes | 3,000 – 10,000 EUR | — |
| New build | — | 15,000 – 30,000 EUR |
| Timeline | 2 – 4 weeks | 8 – 14 weeks |
| Loss of existing SEO | Low | Moderate to high |
| Total cost | 3,800 – 12,500 EUR | 15,000 – 30,000 EUR |
Takeover fits when the technical base is sound but poorly maintained. A rebuild is required if the code is unreadable, obsolete or riddled with debt: fixing it would then cost more than rebuilding.
The risks to secure before switching
The main danger is lock-in: an outgoing agency can block access. Here are the points to lock down before any transfer.
| Item to retrieve | Lock-in risk | Preventive action |
|---|---|---|
| Hosting / server access | High | Require credentials in writing |
| Source code | High | Check the ownership clause |
| Domain name | Medium | Confirm registrant at the registrar |
| Analytics / Search Console | Medium | Request ownership transfer |
| Licences and API keys | Medium | List third-party dependencies |
| Business email accounts | Low | Migrate before termination |
Golden rule: never terminate the old contract before retrieving and verifying every access. A poorly sequenced takeover can turn a 5,000 EUR project into a forced 20,000 EUR rebuild.

Mini case study
Sophie, director of a services SME in Toronto (30 staff), pays 380 EUR/mo to an agency that no longer replies. She is considering a 22,000 EUR rebuild. We run a handover audit at 1,500 EUR: the site is technically sound but has had no updates for 14 months. Remediation at 6,500 EUR (security, performance, SEO fixes) is enough.
Outcome: 1,500 + 6,500 = 8,000 EUR instead of 22,000 EUR, i.e. 14,000 EUR saved and a 3-week timeline instead of 3 months. Sophie keeps her existing ranking and moves to 290 EUR/mo maintenance with contractual reversibility. The upfront audit avoided a needless rebuild.
FAQ
How much does a handover audit cost in 2026? Between 800 and 2,500 EUR depending on site size and stack complexity. This audit is deductible from any remediation and objectifies the takeover-vs-rebuild choice.
What if the old agency refuses to hand over the code? First check your contract: if code ownership is yours, a formal notice often suffices. Otherwise takeover may be impossible and rebuild becomes the only option, hence the importance of initial reversibility clauses.
Does a takeover lose the ranking? No, unlike a rebuild. A takeover keeps the URL, structure and SEO history. That is precisely one of its big advantages: you do not start from zero on Google.
How long for a full takeover? Count 2 to 4 weeks: one week of audit and access retrieval, then two to three weeks of remediation. A rebuild, by contrast, takes 8 to 14 weeks.
When is a rebuild more cost-effective than a takeover? When remediation exceeds 60% of a new site's cost, or when the stack is obsolete (unmaintained technology). Below that, takeover stays more cost-effective.
