How to Hire WordPress Developers in London (Without Getting a Mess)

There are thousands of WordPress developers in London.

Half of them will build you a slow, bloated site.

The other half will disappear after launch.

Finding the real experts is harder than it looks.

Here’s how to hire WordPress developers who actually deliver.

1. Know What Kind of Developer You Need

Not all WordPress developers are the same.

The 4 types:

Theme Customizers

• Modify existing themes
• Use page builders (Elementor, Divi)
• Don’t write much custom code

Good for: Small budgets, simple sites
Not good for: Custom functionality, performance, complex sites

Front-End Developers

• Build custom themes
• Write HTML, CSS, JavaScript
• Focus on design and user experience

Good for: Custom design, branded sites
Not good for: Complex back-end functionality, integrations

Back-End Developers

• Build custom plugins
• Handle integrations (CRM, payment systems)
• Write PHP and work with databases

Good for: Complex functionality, custom features
Not good for: Design work (need a front-end dev too)

Full-Stack WordPress Developers

• Do everything: design, front-end, back-end
• Build complete custom solutions

Good for: Full projects, ongoing development
Cost: Most expensive (but often worth it)

What you need:

• Simple site: Theme customizer
• Custom design: Front-end developer
• Complex features: Full-stack or team (front-end + back-end)

Our team:
We’re full-stack. We handle design, development, and SEO under one roof.

2. Check Their Portfolio (And Actually Look at the Code)

Anyone can show you pretty screenshots.

Real developers show you working sites—and explain what they built.

What to ask for:

• 5–10 recent projects (within last 2 years)
• Live sites (not just mockups)
• Explanation of what they built (custom vs. template)
• Role in each project (did they build it solo or part of team?)

What to check:

Test the sites:

• Load speed (use PageSpeed Insights)
• Mobile experience (open on your phone)
• Functionality (do forms work? Does navigation make sense?)

Look at the code:

• Right-click → View Page Source
• Is it clean or bloated?
• Are there 50 plugins loading on every page?
• Is it using a page builder? (search for “elementor” or “divi” in source)

Red flags:

• Only show sites from 3+ years ago (haven’t worked recently?)
• Can’t explain what they built (didn’t actually build it?)
• Sites are slow or broken (poor quality work)
• All sites look the same (using same template over and over)

Good signs:

• Diverse portfolio (different industries, different designs)
• Fast-loading sites (under 3 seconds)
• Custom work (not just template modifications)
• Can explain technical decisions

3. Ask the Right Technical Questions

You don’t need to be a developer. But you need to ask smart questions.

Questions to ask:

“Do you build custom themes or use templates?”

Good answer:
“Depends on budget and needs. For complex sites, I build custom. For simpler projects, I customize quality themes.”
Bad answer:
“I always use [specific theme].” (One-size-fits-all approach)

“Do you use page builders?”

Good answer:
“I avoid page builders for performance reasons. I hand-code themes or use Gutenberg with custom blocks.”
Bad answer:
“I use Elementor/Divi for everything.” (Performance will suffer)

“How do you optimize for speed?”

Good answer:
“I write clean code, optimize images, use caching, minimize plugins, and test with PageSpeed Insights.”
Bad answer:
“I install a caching plugin.” (That’s not enough)

“How do you handle security?”

Good answer:
“Regular updates, strong passwords, SSL, security plugins, limited login attempts, and regular backups.”
Bad answer:
“WordPress is secure by default.” (Wrong)

“How do you approach SEO?”

Good answer:
“I build SEO into the structure: clean code, fast load times, mobile-first, schema markup, proper heading hierarchy.”
Bad answer:
“I install Yoast.” (Plugin alone isn’t enough)

“What happens after launch?”

Good answer:
“I provide training, documentation, and offer maintenance plans. I’m available for updates and fixes.”
Bad answer:
“Project ends at launch.” (You’re on your own)

4. Review Their Code (Or Have Someone Review It)

If you know basic code, check their work.
If you don’t, hire someone to audit it before you commit.

What to look for:

Clean code:

• Proper indentation
• Comments explaining complex sections
• Follows WordPress coding standards

Performance:

• Minimal inline CSS/JavaScript
• Optimized images
• Efficient database queries

Security:

• Sanitized inputs (prevents hacking)
• Escaped outputs (prevents XSS attacks)
• Uses WordPress functions (not raw PHP/MySQL)

How to check:
Ask to see their GitHub profile or code samples. Real developers will share.

Red flags:

• Refuses to show code (hiding poor quality?)
• Code is messy or uncommented
• Uses deprecated WordPress functions
• Doesn’t follow WordPress standards

5. Check References (And Actually Call Them)

Portfolios can be faked. References can’t (as easily).

What to ask for:
3–5 client references from recent projects (within last year)

Questions to ask references:

1. “Did the project finish on time and on budget?”
2. “How was communication during the project?”
3. “Were there issues after launch? How did they handle them?”
4. “Would you hire them again?”
5. “What could they have done better?”

Red flags:

• Won’t provide references (“everything’s under NDA”)
• References are all from 3+ years ago
• References are vague or scripted
• Can’t reach any references (fake?)

Good signs:

• Multiple recent references
• References speak specifically about their experience
• Minor criticisms (too-perfect references seem fake)
• “Would hire again” confirmation

6. Understand Pricing Models (And Watch for Hidden Costs)

WordPress developers charge in different ways.

Hourly rate:

• London average: £50–£150/hour
• Pros: Pay for exactly what you need
• Cons: Can spiral out of control

Fixed project fee:

• London range: £3,000–£20,000+ depending on complexity
• Pros: Know total cost upfront
• Cons: Scope creep can cause issues

Monthly retainer:

• London range: £1,000–£5,000/month
• Good for: Ongoing development and maintenance
• Not good for: One-time projects

What to ask:

• “What’s included in the price?”
• “What’s NOT included?”
• “What happens if scope changes?”
• “Are there setup fees or hidden costs?”
• “What’s the payment schedule?”

Red flags:

• 100% payment upfront (they could disappear)
• Vague pricing (“depends on what you need”)
• Won’t break down costs
• Charges extra for “revisions” (should include 2–3 rounds)

Our pricing:
Fixed project fees. You know the cost upfront. Includes 2 rounds of revisions. No hidden fees.

7. Test Communication Before You Hire

Bad communication kills projects.

What to test:

Response time:

• Do they respond within 24–48 hours?
• Or does it take days/weeks?

Clarity:

• Do they explain things clearly?
• Or do they hide behind jargon?

Questions:

• Do they ask about your business and goals?
• Or just jump straight to tech specs?

Listening:

• Do they understand your needs?
• Or push their own preferences?

Red flags:

• Takes 5+ days to respond to emails
• Dismisses your concerns
• Doesn’t ask questions about your business
• Uses jargon to confuse rather than clarify

Good signs:

• Responds within 1–2 days
• Asks thoughtful questions
• Explains technical concepts simply
• Proposes solutions based on your goals

Our approach:
We respond within 24 hours. We ask about your business first, tech second. We explain everything in plain English.

8. Start Small (Test Before You Commit)

Don’t hand over a £20,000 project to someone unproven.

Test them first:

• Hire for a small project (£500–£2,000)
• Site audit
• Single page build
• Plugin customization

What you’re testing:

• Quality of work
• Communication
• Timeliness
• Problem-solving

Then decide:
If they deliver, scale up to bigger projects.
If they don’t, you’ve only lost a small amount.

Our offer:
Start with a site audit or single page. If you’re happy, we scale up to full development.

9. Clarify Ownership and Access

You’d be shocked how many businesses don’t own their own websites.

What you must own:

• Domain name (registered in your name/company)
• Hosting account (under your control)
• Theme and plugins (licensed to you)
• Content and images (copyright to you)
• Source code (all custom code is yours)

What to ask:

• “Who owns the domain and hosting?”
• “Will I have admin access?”
• “Do I own the custom code you write?”
• “What happens if we stop working together?”

Red flags:

• Developer owns domain/hosting (you’re locked in)
• Won’t provide admin access
• Claims to own custom code
• Holds site hostage after project ends

Our policy:
You own everything. Domain, hosting, code, content. We provide full access from day one.

10. Discuss Maintenance and Support

Sites need ongoing maintenance.

What to clarify:

• “Who handles updates?” (WordPress core, plugins, themes)
• “What if something breaks?”
• “Do you offer maintenance plans?”
• “What’s your response time for urgent issues?”

Maintenance typically includes:

• Monthly updates (core, plugins, themes)
• Security monitoring
• Backups
• Performance optimization
• Bug fixes

Cost:
£100–£300/month depending on site complexity.

Alternative:
Some businesses handle updates themselves and call developers for fixes only.

Our recommendation:
If you’re not technical, get a maintenance plan. If you are, you can handle basic updates yourself.

What we offer:
Maintenance plans starting at £150/month. Or pay-as-you-go support (£75/hour).

11. Red Flags to Watch For

Walk away if you see these:

❌ “I can build your site in 1 week” Reality: Quality custom WordPress takes 8–12 weeks minimum.

❌ “I don’t need to see your brand guidelines” They’re not interested in your business—just churning out templates.

❌ “SEO doesn’t matter—I’ll add it later” SEO must be built in from the start.

❌ “I use [insert page builder] exclusively” One-size-fits-all approach = poor performance.

❌ “You don’t need backups—hosting handles it” Wrong. Always have independent backups.

❌ Won’t show portfolio or code samples They have something to hide.

❌ Requires 100% payment upfront High risk of disappearing.

❌ Can’t explain technical decisions They don’t understand what they’re doing.

12. Freelancer vs. Agency: What’s Right for You?

Both have pros and cons.

Freelancer:

Pros:

• Lower cost (£30–£80/hour vs. £75–£150/hour for agencies)
• Direct communication (no account managers)
• Flexible (can work on your schedule)

Cons:

• Limited capacity (one person = one skillset)
• No backup (if they get sick or leave, you’re stuck)
• Potential delays (juggling multiple clients)

Good for: Small projects, tight budgets, ongoing small tasks.

Agency:

Pros:

• Full team (designers, developers, SEO experts)
• Redundancy (if one person leaves, project continues)
• Processes (proven systems, faster delivery)

Cons:

• Higher cost (overhead = higher rates)
• Less direct access (go through account managers)

Good for: Complex projects, ongoing development, businesses that need reliability.

Our model: We’re a small agency. You get agency-level quality and reliability, but with direct access to the team. Best of both worlds.

13. Contract Essentials (Don’t Start Without These)

Always get a contract. Always.

What it should include:

• Scope of work (what’s included, what’s not)
• Timeline (milestones and deadlines)
• Payment terms (schedule, method, refund policy)
• Ownership (who owns what)
• Revisions (how many rounds included)
• Support period (30–90 days post-launch)
• Termination clause (how either party can exit)

Red flags:

• No contract (“we can just start”)
• Vague scope (“we’ll figure it out as we go”)
• No timeline
• No termination clause (locked in forever)

Our contracts: Clear scope. Fixed timeline. Fair payment terms. You own everything. Simple termination clause.

14. Questions to Ask Yourself Before You Hire

Make sure you’re ready:

✓ Do I have a clear brief? (goals, features, design preferences)
✓ Do I have a realistic budget? (£3k minimum for custom work)
✓ Do I have a timeline? (8–12 weeks minimum)
✓ Do I have content ready? (text, images, videos)
✓ Do I have someone to manage the project? (on your side)
✓ Am I ready for ongoing maintenance? (sites need updates)

If you answered “no” to multiple questions, pause. Get organized first.

We help with this: We provide project questionnaires, content templates, and timeline planning to make sure you’re ready.

15. How to Evaluate Multiple Developers

Interview 3–5 developers before deciding.

Create a scorecard:

Criteria	Developer A	Developer B	Developer C
Portfolio quality	✓✓	✓✓✓	✓
Technical expertise	✓✓	✓✓	✓✓✓
Communication	✓✓✓	✓	✓✓
Price	£8k	£12k	£6k
Timeline	10 weeks	8 weeks	12 weeks
References	✓✓	✓✓✓	✓

Don’t just pick the cheapest. Pick the best value.

Best value = highest quality at reasonable price.
