The right SEO and web design company plans your site and your search visibility together, shows real work, and gives you a clear quote before you commit. For small and growing London businesses, Ennomark suits owner-led firms that want one team and a site built to generate enquiries. Fat Cow Media suits sector-specific projects, Reactive Graphics suits finance and property brands, and DCP Web Designers suits WordPress and WooCommerce sites. Tenet suits larger builds with integrations, and The Website Design Agency suits buyers who want one all-round package.
Most people start this search because their current site looks fine but brings in few enquiries. Hiring a designer and a separate SEO provider often makes that worse. The designer ignores page structure, and the SEO specialist inherits a site that struggles to rank. A web design and SEO company under one roof removes that hand-off.
Below you will find six London options, each described the same way: what it offers, who it suits and how to start. We publish this on Ennomark’s blog, so we list ourselves first and say so. The other five are described from what each publishes on its own website. A final section gives a side-by-side table and the questions to ask before you hire.
1. Ennomark
Services and approach
Ennomark is a London web design studio where design, development and SEO sit in one team. You deal directly with the person building your site, with no account managers in between, and every layout is planned around your brand instead of a generic template.
The work covers web design, ecommerce and search:
- Custom design and code on WordPress, Wix, Webflow or a fully custom platform
- Ecommerce stores on Shopify or WooCommerce
- On-page, off-page and technical SEO
- Local SEO and Google Business Profile optimisation
- AEO and GEO, which help you appear in AI tools such as ChatGPT, Google AI Overviews and Perplexity
Each build ships with an SEO foundation of headings, meta tags, clean URLs and fast, mobile-responsive pages. Redesigns keep your URL structure and redirect old pages, so you keep the rankings you already earned.
A web design and SEO company should build search visibility into the site from day one, not bolt it on afterwards.
Who it suits and how to start
Owners of small and medium-sized businesses, startups and service firms get the most from Ennomark, along with online retailers that need a store and a brand identity. It states 7+ years and 400+ websites completed, and its portfolio includes Hemet Movers, Qutiee and Ewago.
Timelines are short. A standard site takes 1 to 2 weeks and a larger or ecommerce site 3 to 6 weeks. Packages are flexible and priced on goals, size and requirements, with a free quote and no hidden fees. You can begin with a free consultation or a free website audit, and a strategist replies within 24 hours.
2. Fat Cow Media
Services and approach
Fat Cow Media is a London bespoke web design agency that has worked since 2010. It sells web design together with SEO, branding and online reputation management as one service.
Its SEO offer includes technical SEO audits, penalty recovery and backlink generation, and it runs a dedicated London SEO page. The agency says its approach combines user experience, build standards and conversion thinking, so the site works as a marketing asset.
Who it suits and how to start
This agency suits businesses in a sector it already knows. It lists education, law, hospitality, finance, music, construction, startups, dental and healthcare. A law firm or school gets pages shaped around what its own visitors look for.
To start, you request a call back through its quote page. It does not publish prices, so ask for a written scope that separates the design build from any monthly SEO work.
Sector experience saves time, because a firm that has built a school or law-firm site before already knows what visitors there need.
3. Reactive Graphics
Services and approach
Reactive Graphics works from Soho and reports 20+ years in business and 100+ websites launched. Its services cover web design, web development, brand identity, digital marketing, hosting and support, and pitch deck design.
Search work sits inside its digital marketing offer, so ask exactly what SEO is included before you sign. Its process runs through discovery, planning, development and launch, and it hosts and maintains client sites after launch.
A black-and-white wireframe before any visual design means you agree the structure first, which is also where SEO planning belongs.
Who it suits and how to start
Reactive Graphics focuses on finance, property, B2B and arts and tech clients. It describes its experience as helping boutique companies attract large organisations and high-net-worth individuals, which suits professional services that sell on credibility.
It begins by learning about your business, competitors and goals, then produces a project quote. You see a wireframe first, then a full design, and the site is built in an online development area where you can give feedback.
4. DCP Web Designers
Services and approach
DCP Web Designers is an Ilford agency founded in 2004 that builds WordPress and WooCommerce sites with SEO alongside. It reports more than 500 websites built for start-ups, agencies and larger companies across the UK.
Its sites are designed to be mobile-friendly and easy to use, with the aim of improving search rankings. It also shares short video tutorials so clients can manage their own site after launch.
Who it suits and how to start
DCP suits small businesses that want to edit their own site and online shops that run on WooCommerce. The skills you pay for are set up and guidance, and you then handle small changes yourself.
Reviews are a strength it points to: a published figure of over 380 five-star ratings on Google. Check the Google profile yourself, then contact the agency through its website to discuss scope and price.
A site you can edit yourself saves you paying for every small content change.
5. Tenet
Services and approach
Tenet is a global agency with a London office on Floor 24 of The Shard. It was founded in 2019 and says it has delivered 450+ projects across 15+ countries. Its London web work covers UI/UX research, custom development, redesigns and third-party integrations with CRM and payment tools.
It builds with search in mind, listing SEO-focused builds, speed optimisation and maintenance, and it also offers separate SEO services. Make sure any proposal states which of these are in your price.
Complex integrations such as CRM and payments are where a larger team earns its fee.
Who it suits and how to start
Tenet suits larger or more complex projects, such as companies connecting a site to customer systems or serving several markets. A small local firm with a simple brochure site may prefer a smaller studio that works one to one.
To start, you submit your business details through its contact form and request a custom proposal. Pricing is not published, so compare its quote line by line with the others on your shortlist.
6. The Website Design Agency
Services and approach
The Website Design Agency, known as TWDA, is a London agency that lists website design, SEO, branding and digital marketing together. That is the closest match on this list to a single package for web design and SEO.
Its public information is brief, so treat it as a candidate to verify, not a proven fit. Look at the portfolio and the SEO deliverables it names, and ask which of the four services your quote includes.
Who it suits and how to start
TWDA suits buyers who want one partner for the whole range, from the site to the logo to ongoing marketing. That works best when you value a single point of contact over deep specialism in one field.
Start by asking for examples of sites that gained search traffic after launch, plus a written list of what each month of SEO includes. A firm that answers these clearly is easier to trust with your budget.
When an agency publishes little, your questions do the vetting for you.
How to choose between the six
Side-by-side comparison
The table sets the six side by side, using what each publishes about its own services. Use it to cut the list to two or three firms, then ask those for quotes.
| Company | Base | Web design and SEO offer | Best for |
|---|---|---|---|
| Ennomark | London | Custom design and code, on-page, technical and local SEO, AEO/GEO | Small businesses, startups, service firms, ecommerce |
| Fat Cow Media | London | Web design plus SEO, branding, reputation management | Sector-specific sites such as law, education, hospitality |
| Reactive Graphics | Soho | Web design, development, branding, digital marketing | Finance, property and B2B brands |
| DCP Web Designers | Ilford | WordPress, WooCommerce and SEO | Editable small business sites and shops |
| Tenet | The Shard | SEO-focused builds, integrations, maintenance | Larger, more complex projects |
| The Website Design Agency | London | Website design, SEO, branding, digital marketing | One partner for everything |
Questions to ask before you hire
Put the same five questions to every firm on your shortlist, because identical questions make quotes comparable:
- Who does the SEO work, and what exactly is delivered each month?
- Will a redesign keep my URLs and redirect old pages?
- Which platform will you use, and do I own my domain, hosting and content?
- What reporting will I see, and how often?
- How long will the build take, and what do you need from me?
Set your expectations on timing as well. As a working guide, early on-page SEO improvements show in 4 to 8 weeks and fuller results take 3 to 6 months. Google’s own SEO starter guide lists the basics, so you can check any proposal against it.
Ask every firm the same questions, and the best SEO and web design company usually reveals itself in the answers.
Making your shortlist
The best SEO and web design company is the one that treats your site and your search visibility as a single project. Match the firm to your situation: a sector specialist if your industry is narrow, a larger team if you need integrations, and a close, owner-led studio if you want direct contact and a site built to bring in enquiries.
Pick two or three firms from the table, ask them the same five questions, and compare written scopes before you compare prices. If you want Ennomark’s custom web design on that shortlist, you can request a free website audit or book a free consultation and see how your current site stacks up.
