Finding a good web agency can transform your business. Finding a bad one can waste months of time, thousands of pounds, and leave you worse off than when you started.
The web industry is largely unregulated. Anyone can call themselves a web designer or developer. This means there are brilliant professionals and complete chancers operating side by side - often with websites that look equally professional.
Here's how to tell the difference before you sign anything.
Pricing Red Flags
Money reveals a lot about an agency. Both what they charge and how they communicate about it.
Suspiciously Cheap Quotes
A professional website takes time. Design, development, testing, content, revisions - skilled people doing skilled work. If a quote seems remarkably low, ask yourself: where are they cutting corners?
Cheap websites often mean:
- Template designs with minimal customisation
- No proper testing across devices
- No security considerations
- No training or documentation
- Junior or offshore developers with limited experience
- Work that needs rebuilding in 2-3 years
A website that costs half as much but needs replacing twice as often isn't a saving.
Watch for: Quotes under £1,000 for custom business websites, or prices dramatically lower than other quotes without clear explanation.
No Pricing Information Until You "Book a Call"
While exact quotes require understanding your needs, agencies that hide all pricing are often optimising for sales rather than fit.
Legitimate reasons exist for custom quotes. But if there's no indication of budget ranges, minimum project sizes, or pricing structures, they may be adjusting prices based on what they think you'll pay.
Watch for: Complete refusal to discuss budget ranges, high-pressure sales calls, quotes that mysteriously match your stated budget exactly.
Hidden or Unclear Fees
Some agencies quote low for the build, then add essential items as "extras":
- SSL certificates (security - should be standard)
- Mobile responsiveness (essential, not optional)
- Basic SEO setup (standard practice)
- Training (you need to use the site)
- Content management system (how else would you update it?)
Watch for: Quotes that don't itemise what's included, vague "starting from" prices, essential features listed as add-ons.
Strange Payment Structures
Reasonable payment structures protect both parties. 100% upfront protects only the agency. 100% on completion protects only the client. Something in between is fair.
Concerning structures include:
- Full payment before any work begins
- Large "setup fees" that can't be explained
- Ongoing payments that seem disconnected from ongoing work
- Fees for accessing your own content or making basic changes
Watch for: Demands for 100% upfront, large non-refundable deposits before seeing any work, subscription models with lock-in that exceed the actual hosting costs.
Communication Red Flags
How an agency communicates during sales tells you how they'll communicate during the project - except with less motivation to impress you.
Slow or Inconsistent Responses
If it takes a week to respond to your initial enquiry, imagine how long it'll take when they have your money and a dozen other projects.
Some reasonable delays exist - small agencies have busy periods. But persistent slow communication during the sales phase is a warning. The sales phase is when they're most motivated to impress you.
Watch for: Days between responses, emails that don't answer your questions, having to chase repeatedly for information.
No Clear Process
"How does the project work?" should have a clear answer. Good agencies have developed their process through experience. They know what works.
Vague answers like "we'll figure it out as we go" or "every project is different" might sound flexible, but usually mean disorganised.
Watch for: Inability to explain project phases, no discussion of milestones or deliverables, no timeline structure.
All Jargon, No Plain English
Some technical terms are unavoidable. But agencies that hide behind jargon are often:
- Trying to seem more sophisticated than they are
- Unable to actually explain what they do
- Making simple things sound complex to justify costs
- Not used to working with non-technical clients
Watch for: Conversations where you leave more confused than when you started, reluctance to explain terms, condescension when you ask questions.
No Questions About Your Business
A good agency needs to understand your business to build the right website. If they're proposing solutions without asking about your goals, customers, or challenges, they're selling a product - not solving your problem.
Watch for: Generic pitches that could apply to any business, no interest in your industry or competition, solutions proposed before problems are understood.
Portfolio and Reference Red Flags
Past work is the best predictor of future work. If an agency can't or won't show theirs, that tells you something.
No Real Portfolio
Every established agency should have examples they can share. Excuses like "all our work is confidential" or "we're just building our portfolio" are concerning.
New agencies exist, and some do great work. But they're a higher risk, and pricing should reflect that.
Watch for: Empty portfolio pages, mockups instead of live sites, very old examples that may represent different team members.
Sites That Don't Work
Actually visit the portfolio sites. Are they:
- Still online and functioning?
- Mobile-friendly?
- Loading reasonably fast?
- Actually impressive, or just okay?
If their showcase work has problems, imagine what happens with work they're not showing off.
Watch for: Broken links in portfolios, sites that look dated, mobile experiences that don't work properly.
Won't Provide Client References
References are standard practice in professional services. An unwillingness to provide any should raise questions.
Some clients prefer privacy, and that's reasonable. But an agency with happy clients can usually find someone willing to share their experience.
Watch for: Outright refusal, only providing written testimonials (which can be fabricated), evasiveness about past client relationships.
Misrepresenting Their Work
Some agencies show work they didn't actually do - either from previous jobs or even competitors' sites. This is more common than you'd hope.
Watch for: Inconsistent quality across portfolio, inability to discuss specific project challenges, sites where the agency isn't credited.
Contract Red Flags
Contracts protect both parties. But unbalanced contracts protect one party at the expense of the other. Read carefully before signing.
You Don't Own Your Website
This is the biggest contract red flag. Some agencies retain ownership of the website, essentially leasing it to you. If you stop paying them, the website disappears.
You should own:
- The custom design created for you
- The content you provide or pay for
- Your domain name
- Access to hosting and files
Reasonable exceptions: They may retain rights to their development framework or reusable code libraries. That's different from owning your entire site.
Watch for: Clauses about ownership reverting to agency, licenses instead of ownership transfer, inability to take the site elsewhere.
Excessive Lock-In Periods
Long mandatory contracts (2+ years) protect the agency from having to earn your continued business. They're especially problematic when combined with large upfront payments.
Month-to-month after an initial period shows confidence. "You're locked in for 36 months" shows the opposite.
Watch for: Multi-year minimums, early termination penalties, automatic renewals with long notice periods.
Domain Name Control
Your domain name should be registered in your name, with your contact details. Some agencies register domains under their own accounts, making it complicated (or expensive) to leave.
If they control your domain, they control your online presence.
Watch for: Reluctance to provide registrar access, domains registered under agency accounts, fees to "release" domains.
No Exit Clause
Contracts should specify how to end the relationship, for both parties. If termination is impossible or prohibitively expensive, that's concerning.
Watch for: No termination clause, unreasonable notice periods, substantial penalties for leaving.
Technical Red Flags
You don't need to be technical to spot these warning signs.
No Mention of Security
Security isn't optional. Any professional agency should mention:
- SSL certificates (the padlock in browser)
- Secure hosting
- Regular updates and maintenance
- Backup procedures
If security never comes up, they're either not thinking about it or don't want you to ask.
Watch for: Security treated as an add-on rather than included, no discussion of ongoing updates, no backup strategy.
Outdated Technology
Web technology moves fast. Agencies using platforms or approaches from a decade ago aren't keeping current.
Signs of outdated approaches:
- Flash (dead technology)
- Non-responsive design (mobile is mandatory)
- Custom systems when proven platforms exist
- Resistance to modern platforms without good reason
Watch for: Recommendations of technology they admit is "older but reliable," websites that don't work on mobile, proprietary systems you've never heard of.
No Performance Consideration
Slow websites lose visitors and rank lower in search. If speed is never mentioned, expect a slow site.
Watch for: No discussion of hosting quality, no mention of image optimisation or performance, dismissiveness about speed concerns.
Proprietary Lock-In Systems
Some agencies build on systems that only they can modify. This means you can never leave without rebuilding everything.
Standard platforms (WordPress, Shopify, modern frameworks) mean other developers can help if needed. Proprietary systems trap you.
Watch for: "Our custom platform," inability to work with other developers, no export options.
Promise Red Flags
Some promises sound impressive but are actually warning signs.
Guaranteed Rankings
No one can guarantee Google rankings. Anyone claiming otherwise is either:
- Lying
- Planning to use risky tactics
- Targeting terms no one searches for
Google's algorithm is complex and constantly changing. Competitors are also working on their rankings. Guarantees are impossible.
Watch for: "Guaranteed page 1," "We'll get you to #1," any specific ranking promises.
Unrealistic Timelines
A professional custom website typically takes 8-16 weeks. Faster is sometimes possible; slower isn't unusual for complex projects.
"We'll have you live in 2 weeks" either means corners are being cut, or they're lying.
Watch for: Timelines dramatically shorter than other quotes, promises without caveats about content delivery or feedback turnaround.
"We'll Handle Everything"
While full-service is valuable, you should be involved. Good agencies want your input on strategy, design, and content. Complete removal from the process often means generic results.
Watch for: No discussion of your involvement, decisions made without consultation, treating you as an obstacle rather than partner.
Results Without Context
"We increased traffic by 500%!" sounds impressive until you realise they went from 10 visitors to 50. Metrics without context are meaningless.
Watch for: Big percentages without absolute numbers, timeframes that don't make sense, claims that can't be verified.
What Good Agencies Do Differently
Recognising red flags is half the picture. Here's what good agencies actually look like:
Transparent pricing: Clear about costs, what's included, and what isn't. Willing to explain why things cost what they do.
Clear process: Defined phases, milestones, and deliverables. You know what happens when.
Responsive communication: Prompt replies, clear explanations, answering the questions you actually asked.
Real portfolio: Verifiable work, live sites, willingness to discuss challenges and solutions.
Client references: Happy clients willing to talk. Ongoing relationships, not just one-time projects.
Fair contracts: You own your work. Reasonable terms. Clear exit provisions.
Technical competence: Current technology, security awareness, performance consideration.
Honest expectations: Realistic timelines, no guaranteed rankings, acknowledgment of what they can and can't control.
Interest in your business: Questions about your goals, customers, and challenges. Solutions tailored to your situation.
What You Can Do This Week
You don't need to be an expert to protect yourself. Here are practical steps:
Get multiple quotes. Three is a reasonable minimum. This helps you understand fair pricing and spot outliers - both high and low.
Check portfolios properly. Actually visit the sites. On your phone. Note how they perform and feel.
Request references. Contact at least one past client. Ask about communication, deadlines, and what happened after launch.
Read contracts completely. Before signing. Look specifically for ownership, termination, and ongoing obligations.
Ask about process. If they can't clearly explain how the project works, that's your answer.
Trust your instincts. If something feels wrong during sales - pressure, evasiveness, condescension - it won't improve once they have your money.
Document everything. Keep emails, save proposals, note what was promised in calls. If things go wrong, you'll want records.
The Bottom Line
Most web agencies are legitimate businesses trying to do good work. But enough problematic ones exist that caution is warranted.
Red flags don't always mean disaster - sometimes there are reasonable explanations. But multiple red flags, or serious ones, should make you pause.
The best protection is taking time. Research agencies before engaging. Ask questions and evaluate answers. Compare options before committing.
A website is a significant investment. Spending extra time choosing the right partner is vastly cheaper than recovering from the wrong one.
If an agency doesn't welcome your questions, doesn't clearly explain their work, or pressures you to decide quickly - that tells you everything you need to know.
Good agencies appreciate informed clients. They have nothing to hide and everything to gain from you understanding what they do. That's the kind of partner worth working with.
