The best ecommerce website development company for you depends on your platform, your budget and how fast you need to launch. Ennomark suits small and mid-sized London businesses that want a Shopify or WooCommerce store built quickly by one team. chilliapple suits stores with multiple storefronts, Magento or heavy integrations. Finn Partners suits larger retail and consumer brands. Globe Tech Soft suits businesses that need Magento or Adobe Commerce upgrades, B2B features and back-office integrations.
Choosing is hard because every agency claims to be bespoke, conversion-focused and SEO-ready. Few publish prices or timelines, and a quote can range from a few weeks of work to a year-long programme. You need to compare platforms, scope, support after launch and the real cost of owning the store.
This list covers four London options, with what each builds, who it suits and what it says about timelines and pricing. Ennomark is first because it is our own studio, so judge it on the same facts as the others. Details for the other three come from their own websites, so confirm scope and price in writing before you commit. A comparison table and a short checklist follow the list.
1. Ennomark: best for small and mid-sized London stores
Ennomark is a London web design studio that builds ecommerce stores on Shopify or WooCommerce, with design, development, SEO and branding handled by one team. It has 7+ years of experience and has completed more than 400 websites, including ecommerce stores such as Qutiee and Ewago.
The main difference is access: you work directly with the person building your store, with no account manager in between.
What it builds
Every store is built on Shopify or WooCommerce, whichever suits your budget and how you want to manage the shop day to day. The build covers conversion-focused design with clear navigation, a streamlined checkout and product pages meant to sell. It also includes properly configured payment gateways, mobile-first layouts and an inventory and product setup that stays manageable after launch.
Integrations connect the store to tools you already use, from email marketing to accounting software. SEO basics such as headings, meta tags and clean URLs come as standard, and a redesign keeps your URL structure and redirects old pages so rankings are not lost.
Who it suits
Founders and owners of small and mid-sized businesses, and startups with no in-house web team, get the most from it. It also fits existing retailers whose current store is slow or looks fine but does not sell. If your requirements go beyond standard platforms, Ennomark also offers custom web development with fixed-scope quotes after a discovery conversation.
If you need Magento or an enterprise commerce stack, a larger specialist is the better fit.
Timelines and pricing
Ennomark states that larger or ecommerce sites usually take 3 to 6 weeks, depending on content and complexity. Pricing is by flexible package based on goals, size and requirements, with a free quote and no hidden fees. You keep full ownership of your domain, hosting and content. Support after launch covers maintenance, speed checks, security checks and content updates. A strategist replies within 24 hours of an enquiry, and you can start with a free website review.
2. chilliapple: best for Magento and multi-store builds
chilliapple is a bespoke ecommerce agency that has built sites for UK clients since 2008. It works across Magento, Shopify (as an official Shopify Partner) and WooCommerce, and says its developers also have PrestaShop experience.
Choose chilliapple when your store is complex, such as several storefronts or a Magento migration, rather than a straightforward shop.
What it builds
Its work centres on custom builds, secure payment gateway integrations and API links to third-party systems. It also handles migrations, such as moving a Magento 1 store to Magento 2. Its published work includes multisite Magento stores with independent storefronts and a multi-market platform serving retail and wholesale.
Hosting is offered through a partner, and SEO foundations are built in during development. The agency recommends ongoing SEO work if you want to rank for competitive terms.
Who it suits
It suits established retailers and wholesalers with large catalogues, several brands or a store that has outgrown its first platform. It is also a sensible choice if you want to hand an existing store to a new team. Its clients include businesses that moved their maintenance over from a previous developer.
Timelines and pricing
chilliapple says custom ecommerce design and development starts from £15,000, depending on features and functionality. It does not publish a fixed timeline. It describes five stages: pre-development, design, development, testing and launch, with timings that depend on complexity and how quickly each stage is signed off. You get 30 days of free support after launch for bugs, then a choice of maintenance packages. Budget for those packages from the start.
3. Finn Partners: best for larger retail brands
Finn Partners UK is a London agency that has built ecommerce sites for over a decade and sits inside a wider marketing group. Its ecommerce team covers Shopify, WooCommerce, Adobe Commerce (formerly Magento) and BigCommerce, and for enterprise clients it also works on platforms such as Oracle ATG.
Its edge is breadth: build, SEO, paid media and social teams work under one roof, which suits brands that want growth support, not just a launch.
What it builds
Its feature list includes advanced search, product filters, abandoned cart recovery, stock management, multiple payment options and loyalty programmes. It offers migrations with checks to protect SEO rankings and data, plus integrations with CRMs, ERPs and inventory systems. Security work includes SSL, PCI compliance measures and GDPR support for enterprise clients.
Who it suits
Consumer and retail brands with a marketing budget, and companies that want design, development and traffic generation from one group, are the natural clients. A very small shop may find the scale and cost more than it needs. Its own pages say it recommends platforms based on your goals rather than pushing one.
Timelines and pricing
Finn Partners states that a straightforward Shopify or WooCommerce build can take 12 to 15 weeks, while custom or enterprise builds on platforms like Adobe Commerce may take up to 12 months. It says entry-level Shopify projects may start from the tens of thousands of pounds, with large bespoke builds significantly higher. Quotes are proposal-based. Ongoing support, maintenance and digital marketing are available after launch.
4. Globe Tech Soft: best for Magento upgrades
Globe Tech Soft is a development company serving London and the surrounding area, with a broad platform list. It names WooCommerce, Magento, Shopify, BigCommerce, Adobe Commerce and PrestaShop, plus some older options such as Ubercart and VirtueMart.
It is the most developer-led option here, so it fits technical projects such as upgrades, B2B features and system integrations.
What it builds
Its Magento services include design, integration, upgrades, B2B features and SEO. For Adobe Commerce it lists B2B and B2C builds and integration with order management, CRM and ERP systems. You get access to the back end of your store, and its developers customise designs to your brand before refining functionality.
Its site claims about 250 completed projects and a team of 25. It also lists only four years of experience, so ask to see live stores you can inspect.
Who it suits
It suits businesses already on Magento or Adobe Commerce that need an upgrade, a B2B portal or links to internal systems. It can also help if you want a developer to extend a store rather than redesign it. Its FAQ is blunt about platform trade-offs, calling Magento heavy and costly for many small businesses. Whatever you choose, ask any developer to justify the platform recommendation in writing.
Timelines and pricing
Globe Tech Soft does not publish prices or build times on its ecommerce page, so you need a scoped quote. Ask for a fixed price for each phase, who hosts the store, and what support costs after launch. Compare that quote with the published figures from the other three agencies in the table below.
How to choose an ecommerce developer in London
Pick the developer whose platform experience matches your catalogue, whose price and timeline fit your plan, and who will still be supporting the store a year after launch. Shortlist two or three, then ask each the same questions.
Compare agencies on like-for-like scope, because the cheapest quote often leaves out integrations, migration or support.
Compare the published facts side by side
| Company | Platforms named | Published timeline | Published price signal | Best for |
|---|---|---|---|---|
| Ennomark | Shopify, WooCommerce | 3 to 6 weeks | Flexible packages, free quote | Small and mid-sized stores, startups |
| chilliapple | Magento, Shopify, WooCommerce, PrestaShop | Not published | Custom builds from £15,000 | Multi-store and Magento projects |
| Finn Partners | Shopify, WooCommerce, Adobe Commerce, BigCommerce, enterprise platforms | 12 to 15 weeks, up to 12 months | Entry level in the tens of thousands | Larger retail brands |
| Globe Tech Soft | WooCommerce, Magento, Shopify, BigCommerce, Adobe Commerce, PrestaShop | Not published | Not published | Magento upgrades and integrations |
Timelines are not like for like, because scope differs. Use them to work backwards from your launch date. If you want to open in week 16, a 15-week build must start almost immediately, while a 6-week build leaves you about nine weeks to prepare products, photography and copy.
Ask these questions before you sign
- Which platform do you recommend for my catalogue, and why not the alternatives?
- What is included in the quote: integrations, payment setup, migration, SEO and content?
- Do I own my domain, hosting and content?
- How are redirects handled if I am moving from an existing store?
- What does support cost after launch, and what does it cover?
- Who will I actually deal with day to day?
Ask for answers in writing, and ask to see live stores built on the platform you are considering.
Picking your shortlist
For a small or mid-sized London store, a Shopify or WooCommerce build from a team you can talk to directly is usually the fastest and most affordable route. Move to a larger agency when you need enterprise platforms, Magento, multi-market selling or heavy system integrations. Whoever you shortlist, compare scope, platform reasoning, ownership and support in writing.
If you want a quote to compare against the others, ask Ennomark for a free consultation and quote. Tell the team what you sell and when you want to launch, and you will get a clear view of platform, timeline and cost.
