Drupal 7 Migration Cost in the UK: Real Numbers for 2026

June 16, 2026

Last updated: June 17, 2026

Your Drupal 7 site is still running.

You know it needs to move.

But the question sitting on your desk is the same one it has been for months:

How much is this actually going to cost us?

Drupal 7 reached End of Life on 5 January 2025. No security patches. No bug fixes. No official support. And now with Drupal 12 arriving August 2026 — and Drupal 10 hitting its own deadline on 9 December 2026 — UK organisations that haven't started planning are running out of comfortable runway.

Why UK Organisations Are Acting Now — Not Waiting

The pressure to move isn't just coming from developers. It's coming from insurers, regulators, and Google.

GDPR compliance becomes significantly harder to certify on software with no active security patches. The ICO takes a dim view of organisations running known-vulnerable systems.

Cyber insurers across the UK are now asking whether your CMS is actively supported. A Drupal 7 answer is increasingly leading to higher premiums or outright exclusions.

UK Government Digital Service (GDS) standards and NHS Digital frameworks both require demonstrably secure, maintained platforms — Drupal 7 fails this test.

Google continues to factor site security into rankings. UK Drupal 7 sites are quietly losing ground to competitors who have already migrated.

Drupal 12 is arriving August 10, 2026 — and it requires Drupal 11 as a starting point. Every month you delay makes that journey longer.

The organisations acting now are not panicking. They are planning. The ones waiting until October will be.

Drupal 7 Migration Cost in the UK: Real 2026 Numbers

Based on completed UK migrations and current agency market rates:

Organisation Size	Cost Range	Timeline	Typical Profile
Small (under 50 pages)	£4,000 – £12,000	4–6 weeks	Charity, SME, local business
Mid-size (50–200 pages)	£12,000 – £35,000	6–10 weeks	University dept, regional org
Large (200+ pages)	£35,000 – £80,000	3–6 months	NHS trust, university, govt body
Enterprise + integrations	£80,000+	6–12 months	Complex APIs, compliance reqs

✅ Migrating to Drupal 11 now = ready for Drupal 12 (August 2026) = no second migration cost.

The Cost of Not Migrating — What UK Organisations Are Discovering

Migration cost is only one side of the equation. Here is what delayed decisions are actually costing UK organisations:

Average cost of a UK data breach: £3.4 million (IBM UK Security Report 2024)

ICO fines for inadequate security: up to £17.5 million or 4% of global turnover under UK GDPR

SEO recovery time after Google flags an insecure site: 6 to 18 months

Cyber insurance premium increases for unsupported CMS: 15–40% in 2026

One of our clients — a UK nonprofit — delayed migration for ten months citing budget constraints. Their quote was £14,000. Following a security incident, they spent over £180,000 on incident response, legal fees, notification letters to affected donors, and emergency site recovery. The migration they delayed cost them nearly thirteen times more than the migration itself.

What Actually Drives Migration Cost in 2026

Page count is rarely the biggest cost driver. Here is what actually determines your investment:

Custom Modules

Every bespoke Drupal 7 module must be rebuilt for Drupal 11. Organisations with five to ten custom modules should budget an additional £8,000 to £25,000 for module work alone.

Third-Party Integrations

Salesforce, HubSpot, payment systems, SSO providers, and custom APIs all require rebuilding for Drupal 11 architecture. This is the dominant cost variable at enterprise scale.

GDPR and Accessibility Compliance

UK organisations must meet WCAG 2.1 AA accessibility standards and UK GDPR requirements. Compliance work adds 20 to 30 per cent to typical project scopes.

Theme Rebuild

Drupal 7 used PHPTemplate. Drupal 11 uses Twig. Your theme must be rebuilt from scratch — this is not optional and is consistently underestimated in early quotes.

The Drupal 12 Factor — Why 2026 Is Different

Here is what makes 2026 different from every previous year.

Drupal 12 is arriving August 10, 2026.

And it requires Drupal 11 as a starting point.

If your site is on Drupal 7 today — there is no direct path to Drupal 12.

You have to go through Drupal 11 first.

Every month you delay means:

More security exposure on Drupal 7

Less time to reach Drupal 11 before December 2026 deadline

Missing the clean path to Drupal 12

Paying premium prices when agencies book up in Q4

The organisations migrating now are not just fixing today's problem.

They are positioning for the next two years.

The ones waiting are creating an emergency they could have avoided.

The December 2026 Warning Every UK IT Director Needs to Read

Drupal 10 support ends 9 December 2026.

Organisations that migrate to Drupal 10 now will face another migration in under twelve months. The correct decision is to migrate directly to Drupal 11 — the current supported version — and position cleanly for Drupal 12 in August 2026.

UK Drupal agencies are already booking up for Q4 2026. The organisations acting in June and July will have better choice, better pricing, and less pressure than those who wait until October.

Frequently Asked Questions

How long does Drupal 7 migration take in the UK?

For small sites (under 50 pages), migration typically takes 4 to 6 weeks. Mid-size organisations (50–200 pages) should plan for 6 to 10 weeks. Large enterprise sites with complex integrations may require 3 to 6 months.

Can I migrate Drupal 7 directly to Drupal 12?

No. Drupal 12 requires Drupal 11 as a starting point. There is no direct upgrade path from Drupal 7 to Drupal 12. The correct path is Drupal 7 → Drupal 11, which then positions you cleanly for Drupal 12 when it arrives in August 2026.

Is Drupal 7 still safe to run in 2026?

No. Drupal 7 reached End of Life on 5 January 2025. It no longer receives security patches. Running Drupal 7 in 2026 means known vulnerabilities remain open and unpatched — a significant risk for UK organisations under GDPR and cyber insurance obligations.

What is the cheapest way to migrate Drupal 7 in the UK?

For small sites with no custom modules, a straightforward migration to Drupal 11 can be completed for £4,000 to £8,000. The key to keeping costs down is starting early — organisations that begin now have more time and more agency options than those who wait until Q4 2026.
