Most business owners think about WordPress security in terms of what it costs to protect their site. The more useful calculation is what it costs when protection is absent.
A WordPress care plan from a managed provider costs £75–£250/month. A hacked site — depending on the nature of the attack and how quickly it is detected — can cost anywhere from £500 to £50,000+ in direct and indirect losses. This article breaks down every cost category with realistic figures so you can make an informed decision about protection.
Cost Category 1: Emergency Recovery Fees
The first call most business owners make after discovering a hack is to a developer or security specialist. Emergency recovery is charged at premium rates — it is urgent, unscheduled work that bumps other projects.
| Service | Typical Cost |
|---|---|
| Emergency malware removal (simple infection) | £300–£800 |
| Malware removal (complex / database injection) | £800–£2,500 |
| Full site rebuild after catastrophic compromise | £2,000–£12,000+ |
| Emergency developer call-out (hourly) | £100–£300/hour, 2-hour minimum |
| Forensic investigation (identifying entry point) | £500–£1,500 |
| Google blacklist removal management | £200–£600 (if handled professionally) |
If you have a managed maintenance plan that includes hack recovery, these costs are zero. If you do not, the minimum realistic cost for a professional emergency recovery is approximately £500 — and substantially higher for anything beyond a simple infection.
Cost Category 2: Lost Revenue During Downtime
A hacked site is frequently taken offline — either by the business owner (to prevent further damage), by the hosting provider (who suspends the account due to malware), or by Google (whose ‘Dangerous Site’ warning makes the site effectively unusable).
E-Commerce: The Direct Revenue Impact
| Monthly Revenue | Cost Per Hour of Downtime (Approx.) | Cost of 24-Hour Outage |
|---|---|---|
| £10,000/month | £14 | £333 |
| £30,000/month | £42 | £1,000 |
| £50,000/month | £69 | £1,667 |
| £100,000/month | £139 | £3,333 |
Service Businesses: The Lead Generation Impact
For a service business that relies on its website for enquiries, downtime loss is measured differently — in missed leads and delayed revenue. A law firm, accountancy practice, or healthcare provider losing 10 days of inbound enquiries from their primary lead source can translate to tens of thousands in lost pipeline.
Cost Category 3: Google Blacklisting — The SEO Catastrophe
Google’s Safe Browsing system detects malicious websites and flags them with a ‘Deceptive site ahead’ or ‘This site may harm your computer’ warning. When this happens:
- Organic traffic typically drops 70–95% immediately — most users will not proceed past the warning
- Google Search Console shows a manual action — which must be resolved and reviewed
- Other browsers (Firefox, Safari) display similar warnings, as they use Google’s Safe Browsing data
- Email providers may start flagging emails from your domain as suspicious
| The Recovery Timeline for a Google Blacklisting | |
|---|---|
| Day 1–3: | Site infected, blacklisting occurs (often before the business owner is aware) |
| Day 3–11: | Hack is discovered (average detection time for small business sites) |
| Day 11–13: | Site cleaned and hardened |
| Day 13: | Google reconsideration request submitted via Search Console |
| Day 15–17: | Google reviews and removes blacklist warning (24–72 hours typical) |
| Day 17–45: | Search rankings partially recover |
| Day 45–90: | Full rankings recovery (if no permanent ranking damage) |
The average small business site is infected for 11 days before the owner discovers it. During this time, Google is flagging every visitor. Even after the blacklist warning is removed, SEO recovery takes weeks.
Cost Category 4: GDPR and Data Protection Fines
If your hacked WordPress site stored personal data — customer names, email addresses, order history, payment details — you may have a legal obligation to report the breach to the relevant data protection authority.
| Jurisdiction | Reporting Obligation | Potential Fine (Serious Breaches) |
|---|---|---|
| UK (UK GDPR / DPA 2018) | ICO within 72 hours if high risk | Up to £17.5 million or 4% of global turnover |
| EU (GDPR) | National DPA within 72 hours if high risk | Up to €20 million or 4% of global turnover |
| USA (varies by state) | Varies — California CCPA, state breach laws | Variable — California up to $7,500 per intentional violation |
| All jurisdictions | Individual right to compensation for harm | Unlimited — civil claims from affected individuals |
In practice, the ICO and EU data protection authorities have shown proportionality in fining small businesses — a genuine accidental breach with prompt reporting and remediation rarely results in the maximum fine. However, the administrative burden of a breach notification process, potential legal advice costs, and reputational damage are significant regardless of whether a fine is issued.
Cost Category 5: Reputation and Customer Trust Damage
This is the hardest cost to quantify — and often the most significant. A customer who sees a ‘Dangerous Site’ warning from Google when trying to visit your website does not forget it. A client who receives spam emails ‘from’ your hacked mail server does not easily restore trust.
| Reputation Impact | Estimated Business Cost |
|---|---|
| Customer who saw Google warning — conversion rate | Likely zero for that visit; uncertain for future visits |
| Negative review citing site hack or spam | Indefinite — visible on Google, Trustpilot, etc. |
| Existing client churn due to security concern | Lost lifetime value — industry-dependent, often £1,000–£10,000+ |
| Professional reputation (solicitors, accountants, healthcare) | Regulatory risk + client confidence erosion |

| MINI CASE STUDY: UK E-Commerce Brand — Total Hack Cost Calculated | |
|---|---|
| Business Type: | UK-based e-commerce business selling premium homeware — approximately £45,000/month in WooCommerce revenue |
| What Happened: | A WooCommerce plugin (used for product filtering) had a known SQL injection vulnerability. The site was infected via this vulnerability. Attackers exfiltrated the customer email database (8,200 contacts) and injected a payment skimmer targeting the checkout page. |
| Detection: | The business owner was unaware for 14 days. Discovery came when a customer reported receiving phishing emails referencing their order from the site. |
| Calculated Total Cost: | |
| Emergency security specialist (forensic investigation + cleanup):£3,200 | |
| Site downtime: | 2.5 days while remediation was completed = approx. £3,750 in lost revenue |
| Google blacklisting: | Site was flagged for 6 days = estimated 80% traffic reduction during period |
| Lost revenue during blacklisting period (estimated): £7,200 | |
| Legal advice for GDPR breach assessment: £1,800 | |
| ICO breach notification prepared and submitted (no fine issued, prompt response mitigated risk) | |
| Customer communication email campaign (specialist copywriter + platform): £900 | |
| Estimated customer churn from breach (5% of database): £4,000–£6,000 in lost lifetime value | |
| Total quantifiable cost: | approximately £21,000–£23,000 |
| The WooCommerce plugin with the vulnerability had been flagged as needing an update 4 months earlier. The update was never applied. | |
| The business is now on a Technocrackers Premium Care Plan at £245/month — which includes WooCommerce-specific testing, daily backups, and hack recovery coverage. | |
| Annual care plan cost: | £2,940. Incident cost avoided: £21,000+. |

Frequently Asked Questions
Q: How long does WordPress hack recovery take?
A: Simple recoveries with a clean backup available take 4–12 hours. Complex infections without a backup, or those involving database compromise, take 24–72 hours. Our Premium plan includes priority recovery — we begin within 2 hours of a confirmed incident.
Q: Will my business insurance cover a WordPress hack?
A: Cyber liability insurance may cover hack-related costs — recovery fees, data breach notification, business interruption. Check your policy specifically for cyber coverage. Many standard business insurance policies do not include cyber events. A care plan reduces the risk that the insurance claim is ever necessary.
Q: What if I have no backup and my site is completely destroyed?
A: A full site rebuild from scratch is the only option — which means re-developing your entire website. Costs for a professional rebuild typically start at £2,000 and often exceed £10,000 for complex sites. This is the scenario a daily backup specifically prevents.
Q: How do I know if my site is currently infected?
A: Run a free scan at sitecheck.sucuri.net and check your site against the Google Safe Browsing report at transparencyreport.google.com. These will surface the most common indicators. A professional security audit covers a much broader range of indicators. Technocrackers offers a free audit for business owners.
