This guide is for UK merchants with an existing Shopify or Shopify Plus store that is already trading. Disclosure: Webdigita, who produced this guide, appears at position 3. We assessed ourselves against the same criteria applied to every agency on this list. Our Shopify maintenance services page has full detail on scope and pricing.
- UK ecommerce exceeded £120 billion in 2025 (IMRG)
- 27.8% of all UK retail happened online by early 2026 (ONS)
- Mid-tier Shopify maintenance retainers in the UK average £2,000/mo – boutique specialists start from £1,200/mo
Shopify maintenance in the UK costs £500 to £3,000+ per month depending on store complexity, hours, and whether you need Shopify Plus SLA cover. The agencies doing this well in 2026 are Charle, ChilliApple, Webdigita, Velstar, Eastside Co, Swanky, Space48, We Make Websites, Quickfire Digital and Blubolt – each suited to a different store size and support model.
Quick picks
- Best named Shopify maintenance product: Charle Agency (HelpDesk retainer)
- Best tiered support packages since 2008: ChilliApple (Bronze to Platinum tiers)
- Best governance-led maintenance at mid-market pricing: Webdigita (from £1,200/mo)
- Best for Shopify Plus at enterprise scale: Velstar (Platinum Partner, 100+ team)
- Best for complex integrations and custom app maintenance: Eastside Co
- Best for DTC subscription stores: Swanky Agency
Quick comparison: 10 Shopify maintenance agencies
Agencies ranked by maintenance specialism – structured retainer model, named support product, client retention evidence, and team depth for ongoing work. This deliberately places maintenance-first agencies above larger generalist development agencies where support is a secondary offering.

|---|---|---|---|---|---|---|
| 1 | Charle Agency | Named HelpDesk maintenance product | London | Plus Partner | 11-50 | £££ |
| 2 | ChilliApple | Tiered packages, transparent pricing, since 2008 | London / Kent | Plus Partner | 70+ | £££ |

How we selected and ranked these agencies
I evaluated ten agencies against five criteria: a verifiable Shopify maintenance or retainer offering, named deliverables per tier, client retention evidence, UK presence confirmed from public sources, and Shopify Partner status. Ranking prioritises maintenance specialism over team size. Webdigita appears at position 3 and we applied the same criteria to ourselves as to every other entry. We have not softened our own Think twice section.
Pricing key: ££ = budget (£500-£1,000/mo) · £££ = mid-market (£1,000-£2,500/mo) · ££££ = established (£2,500-£5,000/mo) · £££££ = enterprise (£5,000+/mo)
Agency profiles
1. Charle Agency
The London Shopify agency that built a named maintenance product instead of calling everything support
- Specialisms
- Shopify maintenance (HelpDesk retainer), Shopify Plus development, SEO, GEO, CRO (SiteLab retainer), email marketing
- Office Locations
- London (Vauxhall)
- Team Size
- 11-50
- Notable Clients
- Cambridge Satchel, Billionaire Boys Club, 111SKIN, Muc-Off, Gilbert Rugby, Tropic Skincare, Lando Norris Store
- Pricing
- £££ (mid-market to established)
Why choose Charle Agency
- HelpDesk is a named, structured maintenance product with defined scope – day-to-day support, bug fixes, theme updates, app management – meaningfully different from “ongoing support” in a proposal with no deliverables attached
- Charle Response is an SLA add-on for priority response on urgent issues – the kind of written response time commitment most agencies avoid putting in contracts until something goes wrong
- 150+ Shopify launches and £300M+ in cumulative merchant sales gives this boutique disproportionate pattern-matching ability across store architectures
Evidence sources: LinkedIn (11-50 employees), Shopify Partner Directory (Plus Partner, 150+ builds), agency website (HelpDesk and SiteLab pages, Charle Response SLA), Clutch (verified reviews 2024-2025)
Ideal for
Mid-market Shopify stores generating £500k to £5M who want a structured maintenance retainer with named scope and an optional SLA add-on for priority response.
Think twice if
You are a Shopify Plus merchant at enterprise scale with complex ERP integrations and formal SLA requirements against large penalty thresholds. Charle’s sweet spot is mid-market.
2. ChilliApple
The UK agency that has been doing Shopify maintenance retainers longer than most agencies on this list have existed
- Specialisms
- Shopify Plus development, Shopify maintenance and support packages, bespoke app development, Magento support, migrations
- Office Locations
- London (UK management team), Kent
- Team Size
- 70+ (UK management with India-based development team)
- Notable Clients
- Versapak, Oxford Products Ltd, Merlin Workwear, As One Telecom
- Pricing
- ££ (budget to mid-market, transparent pricing)
Why choose ChilliApple
- Named support package tiers – Bronze, Silver, Gold, Platinum – with defined scope per tier. Transparent tiered pricing is rare in a market where most agencies refuse to publish what a retainer actually includes
- 95%+ client renewal rate on maintenance contracts – a contractually verifiable stat given their packages run on 6 or 12 month formal terms
- Monthly performance snapshots including Lucky Orange heat mapping and SEO health checks built into the support contract, not priced separately
Evidence sources: LinkedIn (70+ employees), Companies House (registered 2008), Shopify Partner Directory (Plus Partner), agency website (support tiers, renewal rate), Clutch reviews
Ideal for
Mid-market Shopify stores needing a cost-effective, clearly scoped support package with named monthly deliverables and a long-term partner who does not disappear when the build project closes.
Think twice if
Your store is heavily Shopify Plus with complex headless architecture or high-volume SLA requirements. ChilliApple’s core strength sits at standard Shopify and mid-tier Plus.
3. WEBDIGITA
Governance-led Shopify maintenance for UK teams that need controlled releases, clear reporting, and pricing that does not require an enterprise budget
- Specialisms
- Shopify maintenance and support, eCommerce maintenance governance, WooCommerce support, Magento maintenance, CRO, technical architecture
- Office Locations
- London, Reading, Birmingham
- Team Size
- 11-50
- Notable Clients
- Long-term eCommerce partnerships averaging 8-10 years across B2B and D2C sectors (full client list available on request)
- Pricing
- From £1,200/mo – approximately 40% below the UK market average of £2,000/mo for comparable mid-tier Shopify maintenance support
Why choose Webdigita
- Staging-first governance model with QA gates, change logs and rollback plans as standard – every change touching checkout or payment logic goes through a controlled release process, not a direct production push
- Pricing from £1,200/mo is approximately 40% below the UK mid-tier market average of £2,000/mo – the lower cost reflects the boutique team structure, not a shortcut on process quality
- Multi-platform support across Shopify, WooCommerce and Magento means cross-platform integrations are managed by one team, eliminating the knowledge gap between separate agency relationships
Evidence sources: agency website (shopify-maintenance-services, ecommerce-maintenance-services, client testimonials), LinkedIn (11-50 employees, founded 2011)
Ideal for
UK Shopify merchants generating £300k to £3M who need governance-led maintenance with controlled releases, monthly reporting, and mid-market pricing without junior developer tiers that trade process for cost.
Think twice if
You need a named Shopify Platinum Partner for an enterprise tender, or a team of 100+ dedicated developers with financial penalty clauses.

Webdigita produced this guide and appears at position 3. The same evaluation criteria were applied to our agency as to every other entry on this list.
4. Velstar
The full-service Shopify Platinum Partner built for brands that have outgrown basic retainers
- Specialisms
- Shopify Plus development, D2C and B2B commerce, CRO, paid media, SEO, email and SMS marketing, ERP and Klaviyo integrations
- Office Locations
- Liverpool, Leeds, Edinburgh, Miami (US)
- Team Size
- 100-120 specialists
- Notable Clients
- Nando’s UK, Twinings, Tangle Teezer, Castore, LKQ Euro Car Parts, Pizza Express, AVON, French Connection
- Pricing
- ££££ (established to enterprise)
Why choose Velstar
- Shopify Platinum Partner status – one of the UK’s highest certification tiers, reserved for agencies with consistent performance across Plus builds and enterprise retainers
- A team of 100+ means development, CRO, paid acquisition and email can run under one account relationship – no hand-off gaps between separate agencies working on the same store
- Their 2025 acquisition of WeTeachCRO added structured conversion testing to the retainer model, so performance improvements are built in rather than sold separately
Evidence sources: LinkedIn (100-120 team confirmed), Shopify Partner Directory (Platinum Partner), agency website (client case studies), Trustpilot
Ideal for
Shopify Plus merchants generating £2M+ who want a single partner managing development, CRO and paid acquisition on a structured retainer with team depth for peak trading.
Think twice if
Your store is on standard Shopify below £500k revenue. Velstar’s Platinum Partner scale and pricing takes them out of reach for merchants who do not need 100+ person capability.
5. Eastside Co
One of the first Shopify Plus Partners in the UK – and the kind of agency that stays after launch
- Specialisms
- Shopify Plus builds and migrations, UX design, SEO, email and retention marketing, Shopify app development, strategic retainers
- Office Locations
- London (Soho), Birmingham, New York, Hamburg
- Team Size
- 80+ in-house (no freelancers, no outsourcing)
- Notable Clients
- Volkswagen, Unilever, Chelsea FC, Carex, Tatti Lashes, Sneak Energy, Route One
- Pricing
- £££££ (enterprise)
Why choose Eastside Co
- One of the first three Shopify Plus Partners in the UK (since 2012) with 500+ stores built – they have seen failure modes that newer agencies have not yet encountered in production
- Fully in-house team, no outsourced developers – which matters when something breaks at 11pm before a campaign launch
- They build their own Shopify apps and maintain Route One on an ongoing retainer since the initial build – same team, same codebase, no knowledge transfer gaps
Evidence sources: LinkedIn (80-strong team), Shopify Partner Directory (Platinum Partner, 500+ builds), agency website (Route One retainer case study)
Ideal for
Established enterprise brands that need a delivery-focused Shopify Plus partner for complex ongoing work – integrations, performance engineering and custom app maintenance.
Think twice if
You need brand-led creative output from your maintenance agency. Eastside’s strength is engineering depth and execution, not brand-led visual strategy.
6. Swanky Agency
The go-to agency for DTC subscription brands on Shopify Plus – a specialism they actually mean
- Specialisms
- Shopify Plus design and development, DTC subscription commerce, CRO, full-funnel marketing, Klaviyo, internationalisation
- Office Locations
- Exeter (UK HQ), Australia, France
- Team Size
- 51-100 (approximately 58 per public sources)
- Notable Clients
- HelloFresh, Huel, Wilkinson Sword, Hotel Chocolat, Natural Instinct, daysoft, Dune London, Purina
- Pricing
- ££££ (established to enterprise)
Why choose Swanky
- One of the first three agencies in Europe to receive Shopify Plus Expert status in 2016 and Platinum Partner in 2025 – a fourteen-year investment in one platform
- HelloFresh and Huel are not names you retain without genuinely understanding subscription commerce – recurring billing logic, churn risk and retention all feed into the support model
- UK, Australia and France offices create genuine timezone coverage for brands trading internationally
Evidence sources: LinkedIn (~58 employees per LeadIQ), Shopify Partner Directory (Platinum Partner), agency website (Growth Accelerator retainer, client roster), UK Ecommerce Awards 2023
Ideal for
DTC and subscription-model Shopify Plus stores in food, drink, health or beauty needing a senior strategic retainer partner who treats maintenance as part of a growth model.
Think twice if
You are running a B2B, marketplace or mass-market store. Swanky’s specialism is narrow by design – a strength for subscription DTC brands and a constraint for everyone else.
7. Space48
The Manchester Shopify Plus agency whose retained client roster confirms their post-launch support holds up
- Specialisms
- Shopify Plus development, UX design, CRO, performance marketing, ongoing website management
- Office Locations
- Manchester (primary), London
- Team Size
- 51-100
- Notable Clients
- Charlotte Tilbury, Cox and Cox, Richer Sounds, Tech21, Function18, Kinetica
- Pricing
- ££££ (established to enterprise)
Why choose Space48
- In operation since 2008 with Ongoing Website Management listed as a core service in their Shopify Partner Directory profile – not buried beneath development services
- Charlotte Tilbury and Cox and Cox are not brands you retain if post-launch support is weak – both have sophisticated in-house teams who hold agencies to a high standard
- Manchester base with genuine UK-wide delivery is useful for merchants whose teams operate outside London
Evidence sources: LinkedIn (51-200 band), Shopify Partner Directory (Plus Partner, ongoing website management listed), agency website (Charlotte Tilbury and Cox and Cox case studies)
Ideal for
UK merchants outside London needing a Shopify Plus partner with strong CX design credentials and genuine ongoing support across lifestyle, homewares, beauty or consumer electronics.
Think twice if
You need a Shopify-only specialist. Space48 now operates across multiple platforms, meaning your dedicated Shopify team may be smaller than their total headcount implies.
8. We Make Websites
The London Shopify Plus agency trusted with the enterprise builds that most agencies would not want to inherit
- Specialisms
- Shopify Plus enterprise builds, headless commerce (Hydrogen), checkout extensibility, internationalisation, ongoing optimisation retainers
- Office Locations
- London (Pentonville Road), New York
- Team Size
- 51-100
- Notable Clients
- Good American, HyperX, Toteme, Hasbro, Huel
- Pricing
- £££££ (premium enterprise)
Why choose We Make Websites
- Headless commerce capability on a support retainer is the real differentiator – they can maintain Hydrogen builds and complex frontend architectures that most agencies will not take responsibility for
- Consistently described as the “safe pair of hands” across independent UK agency roundups – reflecting delivery reliability at enterprise scale
- Long-running optimisation retainers with HyperX and Hasbro demonstrate they hold post-build relationships rather than moving to the next project
Evidence sources: LinkedIn (51-100 band), agency website (London and New York offices, client case studies), Shopify Partner Directory, multiple independent UK roundups (2025-2026)
Ideal for
Large Shopify Plus stores with complex headless architectures, checkout extensibility or multi-market international setups needing a partner with genuine technical depth.
Think twice if
You need SEO-first growth strategy or brand-led creative from your maintenance agency. We Make Websites is a technical delivery agency – content strategy sits outside their natural scope.
9. Quickfire Digital
The Shopify Plus agency whose accelerator packages are built for post-launch growth, not just reactive tickets
- Specialisms
- Shopify Plus design and development, accelerator growth packages, technical support, platform optimisation
- Office Locations
- UK (multiple locations)
- Team Size
- 11-50
- Notable Clients
- Lifestyle, fashion and retail Shopify Plus brands (case studies on website)
- Pricing
- £££ (mid-market)
Why choose Quickfire Digital
- Accelerator packages are built specifically for post-launch growth and support – not a generic retainer rebranded with an energetic name
- Shopify Plus Partner status means they can access Shopify enterprise-tier support channels on behalf of clients when issues escalate beyond standard platform support
- Consistent appearance across independent 2025-2026 UK agency roundups – visibility that reflects client retention, not marketing spend
Evidence sources: LinkedIn (11-50 band), Shopify Partner Directory (Plus Partner), agency website (accelerator package structure), multiple UK agency roundups (2025-2026)
Ideal for
Growing Shopify Plus merchants who want a single agency managing technical support and iterative improvements post-launch without separating maintenance and growth into different retainer agreements.
Think twice if
You need a proven track record with large named enterprise brands. Quickfire’s portfolio skews mid-market and support depth at enterprise scale is less documented than the larger agencies above.
10. Blubolt
The boutique Shopify Plus agency that specialises in simplifying the stores others made complicated
- Specialisms
- Shopify Plus migrations, tech stack simplification, ongoing support, store performance optimisation, fashion and lifestyle eCommerce
- Office Locations
- UK
- Team Size
- 11-50
- Notable Clients
- Never Fully Dressed, WYSE London, Bella Freud, Snowdonia Cheese, JING Tea
- Pricing
- £££ (mid-market to established)
Why choose Blubolt
- 400+ ecommerce projects delivered is significant volume for a boutique agency – they have encountered the platform edge cases that trip up teams with narrower delivery histories
- Same team handles both the migration and the ongoing retainer, eliminating the knowledge transfer gap responsible for most post-migration incidents in the first 90 days
- Reputation for tech stack simplification during migration – fewer moving parts means fewer failure modes in the support retainer that follows
Evidence sources: LinkedIn (11-50 band), agency website (400+ builds, client case studies), Shopify Partner Directory (Plus Partner), multiple UK agency roundups (2025-2026)
Ideal for
Retailers migrating from Magento, WooCommerce or bespoke platforms to Shopify Plus who want the same agency handling the migration and the subsequent maintenance retainer.
Think twice if
You need enterprise-scale support with formal SLA guarantees and a large dedicated team. Blubolt operates at boutique scale – quality is high but the capacity ceiling is lower than agencies above them on this list.
How to choose the right Shopify maintenance agency
Agency fit by store revenue
| Annual store revenue | Store type | Recommended retainer tier | Typical monthly range | Agencies on this list |
|---|---|---|---|---|
| Under £500k | Standard Shopify | Boutique or specialist | £500-£1,000/mo | ChilliApple, Quickfire Digital |
| £500k-£2M | Shopify / entry Plus | Mid-market specialist retainer | £1,000-£2,500/mo | Webdigita, Charle,ChilliApple, Blubolt |
| £2M-£10M | Shopify Plus | Full-service Plus partner | £2,500-£5,000/mo | Swanky, Webdigita, Space48, Velstar, Charle (SiteLab) |
| £10M+ | Shopify Plus / headless | Enterprise partner with formal SLA | £5,000+/mo | Velstar, Eastside Co, We Make Websites |
Budget planning guide
| Tier | Monthly range | What is typically included |
|---|---|---|
| Basic | £500-£1,000/mo | Theme updates, app compatibility, monthly monitoring, reactive bug support |
| Mid-tier managed | £1,000-£2,500/mo | Account manager, monthly reporting, development hours, Core Web Vitals monitoring, SEO health |
| Plus retainer | £2,500-£5,000/mo | CRO testing, priority response, dedicated senior developer, quarterly strategy, checkout coverage |
| Enterprise SLA | £5,000+/mo | Formal SLA, dedicated team, headless architecture support, ERP monitoring, executive reporting |
Most common mistakes UK merchants make
- Confusing development hours with maintenance. A block of dev hours is not a maintenance contract. Maintenance requires staging environments, QA gates, change logs and rollback plans. Hours without process are expensive access to a developer.
- Signing with the build agency by default. The skills to build a Shopify store and maintain it safely at scale are not the same. Build agencies optimise for delivery speed. Maintenance requires a different engineering mindset.
- Choosing on headline price without checking team structure. A £600/month retainer routed through junior offshore developers is not the same product as £600/month from a senior-led UK team.
- Not defining response time in writing before signing. “We respond quickly” is not an SLA. Require specific response time commitments in hours, written into the contract for different severity levels.
- Paying for hours that expire at month-end. Hours that reset regardless of usage is a subscription model for the agency’s benefit. Unused hours should carry forward.
- Assuming the agency knows your stack from day one. Every incoming maintenance partner should run a discovery on your codebase before committing to scope. If they skip it, they are pricing on assumptions.
The retainers that hold up for years define what is in scope, specify response time in hours, include staging-first as a non-negotiable for checkout changes, and produce a monthly summary showing what was done and what is queued. Our eCommerce maintenance services page covers the governed release workflow we use in practice.
Final recommendation
The Shopify maintenance market in 2026 has split into two tiers. Large Shopify Platinum Partners – Velstar, Eastside Co, Swanky, We Make Websites – carry the team depth for enterprise SLA work and complex Plus environments. Focused specialists – Charle, ChilliApple, Webdigita, Quickfire Digital, Blubolt – deliver structured maintenance to mid-market merchants without the enterprise overhead in the price.
The most common error is mismatching agency tier to store size. An agency built for £10M+ stores will price a £500k store out of the conversation. An agency built for mid-market will hit a ceiling on Black Friday.
For stores generating £500k to £5M, Charle’s HelpDesk is the most clearly structured maintenance offer in this market. For mid-market merchants who want governance-led maintenance with transparent pricing from £1,200/mo, Webdigita and ChilliApple are both worth a conversation. For Shopify Plus at enterprise scale with formal SLA requirements, start with Velstar or Eastside Co.
Whichever agency you speak to: ask to see a sample monthly report before signing. The quality of that document tells you more about their maintenance process than any sales call.
