Website Maintenance for UK Stores and B2B Sites, With Every Update Tested First
Your site takes orders or trade enquiries every day. It runs on WooCommerce, Magento, Shopify or custom code, and it feeds Xero or Sage, Linnworks or Mintsoft, Stripe or GoCardless, and Royal Mail or DPD labels. The agency that built it has gone quiet. FactoryJet takes it over, tests every update on a hidden copy before release, and checks that orders still reach the systems behind it.

Website maintenance is the monthly work that keeps a live site safe and earning: software updates proven on a hidden copy before release, backups you can restore, security patches applied within 14 days of a critical fix, and repairs when something breaks. For a UK store or B2B site it should also check that orders, stock and invoices still flow to Xero, Sage, your stock tool and your couriers.

A staging site is a hidden duplicate of your website, invisible to customers, where updates are tried first. A plugin (or app, or extension) is an add-on that gives a site a feature, such as a payment method or a Xero connector. An integration is the link that moves data between your site and another system, such as orders into Sage or stock from Linnworks. An API is the doorway one system offers so another can read or send data, and platforms release new versions of it over time. CVSS is the common 0 to 10 score for how serious a security flaw is.
Most care plans stop at the website. A costly failure often sits one step further out: a plugin update that leaves the checkout working but stops orders reaching the accounts, so the gap only shows at month end. That is why every month includes one test order traced all the way through.

What our website maintenance services cover
Nine jobs, done every month and written down. The first four keep the site safe. The last five keep it earning, and they are where a site with real orders differs from a brochure site.
Tested updates
WordPress core, themes, plugins, Magento patches, Shopify app changes and code libraries, applied to staging first, tested against your forms and checkout, then moved to the live site.
Backups we restore
A copy of files and database taken on a set timetable, kept off your server, and restored to a test copy every month, so the first restore is not the day you need it.
Security patching
Critical and high-risk fixes inside the Cyber Essentials deadline, plugin vulnerability checks, admin user reviews, two-factor logins and removal of software that no longer gets fixes.
Hosting and PHP upgrades
Server software kept on supported versions. Each PHP move, such as 8.2 to 8.3 or 8.4, is tried on staging well before the old version loses security fixes.
Integration checks
A real test order followed into Xero, Sage (50, 200 or Intacct), QuickBooks, NetSuite, Business Central, Odoo or Brightpearl, and stock checked against Linnworks or Mintsoft. See our Shopify Xero integration page for one of these links in depth.
Marketplaces, payments, couriers
Feeds to Amazon.co.uk, eBay UK, OnBuy, ManoMano, the B&Q marketplace and Zalando for EU sales. Payments through Stripe, GoCardless, Klarna and Clearpay. Labels from Royal Mail, DPD and Evri.
Speed and search health
Monthly checks on the pages that bring in orders, so a heavy plugin or a large image does not quietly slow them down, and an update does not break redirects or block search crawlers.
Changes and small builds
New landing pages, product templates, edits to forms and modest new features, handled by people who already know your code. Anything larger is quoted as a fixed price first.
Website support when it goes wrong
If the site is hacked or goes down, we restore, find the cause and close it. If personal data may be involved, you get the facts quickly, because the ICO reporting clock starts when you become aware.
Why a UK site that looks fine can still be losing orders
Connectors break silently. A store can take payment perfectly while the order never reaches Sage, the stock count in Linnworks drifts, or the Royal Mail label is never created. The customer sees nothing wrong until the parcel does not arrive. A care plan that only checks the homepage loads will miss all three.
The platforms move on a timetable. Shopify ships a fresh API version each quarter and keeps each one running for a minimum of 12 months. Apps and custom links written against an old version stop working when it retires. WordPress.org recommends PHP 8.3 or newer, and says PHP 7.4-era versions have reached end of life and may expose a site to security vulnerabilities.
Workarounds can put VAT records outside the rules. When the store to Xero link fails, the usual fix is a member of staff copying daily totals across. HMRC’s VAT Notice 700/22 says copy and paste is not a digital link for Making Tax Digital, while API transfer and CSV import are. Repairing the connector quickly keeps the chain digital. Your accountant confirms the VAT detail.

How we take over and maintain a UK website, in seven steps
The same steps whether we built the site or someone else did. Nothing on your live site changes until step five, and you see a written check of your own site before you sign anything.
- 01
A free check of your site
From the outside, with no logins: platform and versions, PHP, the SSL certificate behind the padlock, visible plugins, speed on key pages and obvious security gaps. You get it in plain English, urgent items first.
- 02
Access and ownership
We confirm the domain, hosting, store and licences sit in your company’s name, collect logins you can remove later, and plan moves for anything still held by the old agency.
- 03
A full inventory
Every plugin, app, theme customisation and scheduled task, plus every system the site talks to: accounts, stock, marketplaces, payments and couriers, with who owns each record.
- 04
Backup and a restore test
A complete backup taken and restored on a staging copy. Until a restore has worked once, no update is applied to anything.
- 05
Urgent fixes, quoted first
A PHP release past its support date, plugins their authors no longer update, former staff still holding admin logins, a contact form that fails quietly. Each fix is listed with a fixed price in writing, and you approve it before we start.
- 06
The monthly cycle
Updates on staging, tests on forms, checkout and a traced test order, then the live release with a fresh backup ready. Security fixes rated critical go out inside the Cyber Essentials deadline.
- 07
A written report and a review
Every change made, every problem spotted, and the questions only you can answer. Every few months we review the scope with you, because a site that changes needs different care.
Next step
Find out what is out of date on your site before it breaks
Send the address. We check versions, backups, security and speed from the outside, then send a short note listing the urgent items, the ones that can wait, and which of your integrations we would test first.
Doing it yourself vs your host’s plan vs a freelancer vs a maintenance team
Each option suits someone. For a site that takes orders and feeds back-office systems, the rows that matter most are testing, integrations and cover when someone is away.
Swipe sideways to see every column.
| What you get | Maintenance team (FactoryJet) | Do it yourself | Host’s managed plan | Freelancer |
|---|---|---|---|---|
| Best fit | Sites that take orders or trade enquiries | Simple sites, confident owner | Server upkeep only | Smaller sites, steady scope |
| Updates tested on staging | Every update | Rarely | Core only, sometimes | Depends on the person |
| Integrations checked (Xero, Sage, Linnworks) | Test order traced monthly | When something breaks | Out of scope | If they built them |
| Backups restore-tested | Monthly | Rarely | Server backups, untested | Varies |
| Cover during holidays and illness | Team cover | You | For the server | One person |
| Changes and new features | Same team, quoted first | Within your skills | Not offered | Usually |
| Accounts in your name | Always | Yes | Hosting held by the host | Ask |
These mix well. Plenty of UK businesses keep a good host for the server, an in-house marketer for content, and bring us in for the developer side. What matters is a written split of who owns which job.
Some managed WordPress hosts now test plugin updates for you. Kinsta’s Automatic Updates add-on updates all plugins and themes, compares screenshots before and after, and restores a backup if a change is detected. WP Engine’s Smart Plugin Manager takes a full backup first, compares chosen pages on desktop and mobile, and rolls back when a visual test fails; you can add checkout and cart pages to that test. Both check how pages look. Neither page describes following an order into Xero, Sage or a courier, which is the gap a maintenance team fills.

What website maintenance costs in the UK
Published UK prices run from about £15 to over £2,000 a month, because they price different jobs. Rattlesnake, a London studio, reviewed 15 UK providers’ published plans on 19 August 2026 and grouped them into four bands. Red Evolution, an agency with offices in Aberdeen, Edinburgh and London, puts full management that adds SEO, content and development at £500 to £2,000 or more a month.
Watch VAT. In Rattlesnake’s sample some providers quote plus VAT, one includes it and several do not say. At 20%, a £79 fee before VAT is £94.80. Red Evolution’s article does not state VAT either way. Ask every provider for a figure that says which.
These are market figures, not FactoryJet prices. We quote the takeover work and any ongoing support you choose as fixed prices in writing, after the free check.

Terms for website maintenance with FactoryJet
FactoryJet has served 500+ businesses since 2014. We design, build and support stores and B2B sites, and maintenance is part of that same contract. We work remotely with UK businesses and hold calls in UK business hours.
- A check on your own site before you sign. You see a written review of your actual website.
- Fixed prices in writing. The takeover, each fix and any ongoing support you choose are quoted as fixed prices after a short scoping call.
- You own it from day one. Domain, hosting, store, code, licences and every login stay in your company’s name.
- Hosting and licences at cost. They can run in your own accounts, billed to you directly, with no markup from us.
- Defects covered. Faults in work we deliver are fixed inside the price, for a cover period agreed before work starts.
- No monthly minimum for changes. Each change outside the agreed scope is quoted and approved first.
A written brief gets a written answer to every question. These five things make it quick:
The UK security rules a maintenance plan should work to
Patch inside 14 days. The NCSC’s Cyber Essentials requirements, version 3.3 from April 2026, say updates that fix critical or high-risk flaws must be applied within 14 days of release. A flaw counts if the vendor rates it critical or high, or if it scores 7 or more on CVSS v3. Software that no longer gets fixes must be removed. Off-the-shelf web applications, such as WordPress, WooCommerce and Magento, are normally in scope. Bespoke custom code is out of scope.
Breaches have a 72-hour clock. The ICO says a notifiable personal data breach must be reported without undue delay and no later than 72 hours after you become aware of it. If a processor working for you has the breach, it must tell you without undue delay. A hacked checkout or a leaked customer export can start that clock, so the first hours need facts.
Attacks are routine. The government’s Cyber security breaches survey 2025/2026 found 43% of UK businesses reported a breach or attack in the previous 12 months: 65% of medium businesses and 69% of large ones. Bigger firms are found more often, and a website is one of the doors.

We are not lawyers. We keep the site patched and give you the facts; reporting decisions and legal advice stay with you and your adviser.

Before the first update, we draw every system your site talks to on one page. The monthly test order follows that map, so a broken link shows up in our monthly report before your month-end close.
Platforms we maintain, and UK sites we work on
WordPress and WooCommerce get the most attention, because plugins carry the most risk, so WordPress support is the largest share of the work. See our UK WooCommerce page. Magento and Adobe Commerce need patches applied with care; Magento support is covered on our UK Magento page. Shopify and Shopify Plus stores need app, theme and integration care as API versions retire; see Shopify maintenance services in the UK. Custom Next.js and headless builds (a custom front end on a separate store engine) are covered too.
If maintenance has become patching a site that no longer fits the business, a rebuild may cost less over two years. Our UK ecommerce redesign page sets out when that is true. In the US, see our website maintenance services page.
GPSUK
A UK promotional products supplier. We built its trade storefront on Commerceflo, where business buyers log in, see their own account pricing and move from quote to order. It is live, and our SEO and AI search work on it continues. Read the case study.
Sow Easy
A UK wholesale client. We are building a WordPress WooCommerce trade store that reads stock, pricing and SKUs (product codes) from Odoo. The store and the Odoo link are being tested on staging, and launch is still ahead. Read the case study.
Why they matter here
Both are sites where the store and the back office must agree. Monthly maintenance needs the same habit: every update is tested against the systems behind the site as well as the pages.
What UK buyers ask before they choose a maintenance provider
Two questions come first: what the work covers, and what it costs. That is why this page lists the nine monthly jobs and shows the market bands with their sources, rather than a vague “it depends”.
Many buyers also ask for website management services, or plain website support when something has already broken. The work overlaps, so we answer both. Maintenance keeps the site safe, and changes and small builds come from the same team when you need them.
Website maintenance questions UK businesses ask us
What maintenance covers
What do website maintenance services include?
The baseline is keeping the platform, theme and add-ons current, plus backups, security checks and fixes when something breaks. For a UK business site that takes orders or leads, we add tests of forms and checkout after every update, checks that the links to Xero, Sage, Linnworks or your courier still post correctly, speed checks on real pages, and a written log of every change that month.
Does a business website need monthly maintenance?
If it earns money, yes. Software around your site changes every month whether you touch it or not. PHP 8.2 loses security support on 31 December 2026, and Shopify ships a new API version every three months. A site left alone for a year usually has a backlog of updates that are riskier to apply all at once.
What is the difference between website maintenance and website management services?
The words overlap, and UK agencies use them loosely. Maintenance usually means keeping the site safe and working: updates, backups, security and fixes. Management often adds the work of changing the site: new pages, content, campaign landing pages and reporting. Ask any provider for a written list of tasks. The list tells you more than the name of the plan.
Who maintains a website, and is that a webmaster’s job?
On most UK business sites, three parties share it. The host runs the server. The owner or an in-house marketer edits content. A developer or agency handles updates, code and integrations. “Webmaster” is an older name for one person doing all three. Whoever does it, put the split in writing, so a failed update or a broken Xero sync has a named owner.
How often should a website be maintained?
At least once a month, with urgent security fixes going out sooner. Cyber Essentials sets 14 days for fixes to critical or high-risk flaws. Plugin and theme updates, a backup restore test and a traced test order fit a monthly cycle. Bigger jobs, such as a PHP upgrade, are planned a few times a year around your trading calendar.
What is a website care plan, and is it worth paying for?
A care plan is a monthly maintenance service sold as a named package, often with tiers. Cheaper tiers are mostly automated updates and backups. Higher tiers add developer time, testing and change requests. The useful questions are whether updates are tested on a copy of the site before going live, and whether anyone ever restores a backup to prove it works. If both happen every month, it is worth paying for.
Can you maintain a site that a different agency built?
Yes. We start with a takeover check: who owns the domain, hosting and licences, what is installed, which systems the site talks to, and what is out of date. You get that list in writing, with urgent items marked, before any monthly work is agreed.
What if our old developer will not hand over the logins?
Start with what is in your company’s name. The domain registrar, the hosting account and any paid plugin licences can usually be recovered by the account holder through the provider’s own support, with proof of ownership. We help you work through each one. Where an account sits in the old agency’s name, we plan a move to a new account in yours.
Cost, VAT and pricing
How much does website maintenance cost in the UK?
Rattlesnake, a London studio, sampled 15 UK providers in August 2026 and found entry care plans at £15 to £59 a month, managed business care at £60 to £149, and ecommerce or advanced CMS care at about £100 to £250 a month or a custom quote. Those are market figures, not our prices. VAT treatment varied between providers in the sample.
How much do website maintenance packages cost for an online store?
In Rattlesnake’s August 2026 sample of 15 UK providers, care for stores, memberships and integrated platforms sat at about £100 to £250 a month or a custom quote, and development retainers for revenue-critical sites at £149 to £379 or more. Stores cost more because checkout, payments and stock sync need testing after every update. Each system the store talks to adds work.
Are UK maintenance prices quoted with or without VAT?
Both, which is why like-for-like comparison is hard. In Rattlesnake’s sample of 15 published plans, some providers quoted plus VAT, one included it and several did not say. At the standard 20% rate, a £79 fee before VAT becomes £94.80. Ask every provider for a figure that states VAT either way before you compare.
Why do some agencies charge £500 a month or more?
Because the plan includes more than maintenance. Red Evolution, a UK agency with offices in Aberdeen, Edinburgh and London, puts basic website management at £50 to £300 a month and full management at £500 to £2,000 or more, where the higher figure adds SEO, content, analytics and ongoing development. Check which of those you need before paying for all of them.
How does FactoryJet price website maintenance?
There is no FactoryJet rate card on this page, because two sites on the same platform can need different care. After a free check of your site, FactoryJet quotes the takeover work and any ongoing support you choose as fixed prices in writing. Changes outside that scope are quoted and approved one at a time, with no monthly minimum for work you do not use.
Platforms and integrations
Do you offer WordPress support and WooCommerce maintenance?
Yes. WordPress maintenance and WooCommerce care take the most work, because plugins are the usual way in for attackers and the usual cause of a broken checkout. WordPress.org recommends PHP 8.3 or newer, and says PHP 7.4-era versions have reached end of life and may expose a site to security vulnerabilities. PHP.net ends security support for PHP 8.2 on 31 December 2026. We plan each PHP upgrade on a staging copy, test the plugins against it, then move the live site.
Do you provide Magento support and look after Shopify stores?
Yes. Magento and Adobe Commerce need security patches and extension updates applied with care, and we have a separate UK Magento page for that work. Shopify patches its own platform, but custom apps, theme code and integrations still need planned updates as Shopify retires API versions, each supported for at least 12 months. Custom Next.js and headless builds are covered too.
Our store talks to Xero, Sage or Linnworks. Is that part of maintenance?
It should be, and it is the part most care plans leave out. A plugin update can quietly stop orders reaching Xero, Sage, QuickBooks, NetSuite, Business Central, Odoo, Brightpearl, Linnworks or Mintsoft, and nobody notices until month end. We check those links after each update by following a real test order through to the other system and comparing the totals.
What happens to Making Tax Digital if our store to Xero link breaks?
If staff fill the gap by copying totals across by hand, that step is no longer a digital link. HMRC’s VAT Notice 700/22 says copy and paste does not count as one, while API transfer and CSV import do. Fixing a broken connector quickly, rather than working around it for weeks, keeps your VAT records inside the rules. Confirm any VAT question with your accountant.
Do you check marketplace, payment and courier connections?
Yes, where they run through your site. That covers stock and order feeds to Amazon.co.uk, eBay UK, OnBuy, ManoMano and the B&Q marketplace, payments through Stripe, GoCardless, Klarna and Clearpay, and labels and tracking from Royal Mail, DPD and Evri. Each one is a place an update can break something, so each one is on the monthly test list.
Security and UK rules
How quickly should security updates be applied?
The NCSC’s Cyber Essentials requirements, version 3.3 from April 2026, say updates fixing flaws the vendor rates critical or high risk must be applied within 14 days of release. Off-the-shelf web applications are in scope by default; bespoke custom code is out of scope. Even if you are not certified, 14 days is a sensible ceiling for a site that handles customer data or payments.
What happens if our website is hacked?
First we stop the damage, switching the site to a holding page if that is safer, put back the last copy we know is clean, trace how the attacker got in and shut that route, rotate every password and key, and ask Google to review any warnings. If personal data may have been exposed, the ICO says a notifiable breach must be reported without undue delay and no later than 72 hours after you become aware. That decision is yours, and we give you the facts fast.
Does maintenance cover UK GDPR and cookie consent?
We maintain the technical parts: the cookie banner works and blocks tags until consent, forms send data only where they should, old admin users are removed and backups are stored securely. We do not give legal advice. Your privacy notice and the decisions about what data you collect stay with you and your adviser, and we make the site match what you decide.
Working with us
Will maintenance updates take our site offline?
Not usually. Every update runs on the hidden staging copy before anything else, and the live site changes only after it passes there. Larger jobs, such as a PHP upgrade or a Magento patch that needs a database change, are scheduled outside your busy hours, agreed with you in advance, and done with a fresh backup ready to restore.
Who owns the website if we stop using you?
You do, from day one. The domain, hosting, store, licences, code and analytics stay in your company’s name, and we work through logins you can remove. If you leave, you get a full backup and our notes on how the site and its integrations are set up. Nothing is held back.
Can you work alongside our in-house team or IT provider?
Yes. Many UK businesses have a marketing team that edits content and an IT provider that runs email and laptops. We take the developer side: updates, code, integrations and fixes. We agree in writing who owns what, so a broken form or a failed Xero sync never falls between three parties. Calls run in UK business hours.
Can we send a brief or an RFP for website maintenance?
Please do. A written brief gets a more useful reply than a form. Include the site address, platform and host, the systems it connects to, who built it, what went wrong in the last year, and any supplier questionnaire or data processing agreement your procurement needs. The founder replies within 24 hours, and we answer every question in writing.
Find out what your website needs before something breaks
Send your name, work email and site address. The founder replies within 24 hours with what we found from the outside and what we would fix first. You keep every account, whatever you decide.
