Written summary after the upgrade

London businesses are regularly asked by clients and insurers to evidence basic cyber hygiene, and an outdated PHP version is among the first things a scan will show.

PHP security for businesses in London

London is the UK’s largest business centre, with finance, law, media and retail alongside a vast number of agency-run websites. The newest PHP security release fixes CVE-2026-109618 and CVE-2026-109619, both rated 9.2. Sites on versions below 8.2.35, 8.3.36, 8.4.27 or 8.5.12 are exposed, and so is anything on PHP 8.1 or older. Application updates alone cannot fix a flaw in the PHP runtime.

The sites we see most often in this kind of market, and why PHP matters to each:

Finance and fintech. Finance-related sites face tougher questions from partners and auditors, and an unpatched server is hard to defend.
Legal and accounting. Law and accounting practices handle confidential client details through contact forms and portals.
Online retail. Online shops hold customer accounts and order histories, so a flaw that runs code on the server can expose far more than the storefront pages.

What an upgrade might look like in London

Example: an agency-built site for a professional firm on a managed server. We would confirm which PHP version the host runs, upgrade it, and document the change for the client’s records.

Local rules to keep in mind

The UK GDPR and the Data Protection Act 2018 require appropriate technical security, and the ICO expects serious personal data breaches to be reported within 72 hours of the organisation becoming aware of them.

How we work with London businesses

We work remotely through your hosting and WordPress logins. We do not have an office in London; we serve businesses there from our team. Scheduling is in your local time, GMT (UTC+0), moving to BST (UTC+1) in summer. We carry out upgrade work outside UK business hours and keep a rollback ready until you confirm everything works.

What the upgrade covers

Version and extension audit of your hosting
Backup, then a trial upgrade on a copy of your site
Compatibility fixes, including removed PHP functions
Live switch, PHP restart and verification of key pages
Written confirmation of the new PHP version

We scope the hours before we start, and the work is billed at your plan rate or the published hourly rate. See pricing and the PHP upgrade services overview.

Questions we hear

Our insurer asks about patching. Can you help with that?

We can give you a dated summary of the PHP version before and after the upgrade, which you can share with an insurer or auditor. What they accept is up to them.

What if a plugin will not work on the new PHP version?

We look for a maintained replacement or a newer version first. If neither exists, we can patch the specific lines that fail and tell you what changed.
