The fastest way to add AI chat to a Fasthosts SiteBuilder site. SmartWidget deploys via a single JavaScript snippet pasted into Site Editor > Settings > Custom HTML. Reads your existing site, configures itself, and goes live in under five minutes. £19/month, no contract, cancel any time.
An AI chat widget for Fasthosts SiteBuilder replaces three pieces of legacy site tooling at once: the contact form that nobody replies to, the live chat that only works in business hours, and the FAQ page visitors never read. SmartWidget on Fasthosts SiteBuilder handles all three jobs from a single line of JavaScript pasted into Site Editor > Settings > Custom HTML. It reads your site, builds the knowledge base, and goes live in five minutes. From £19/month, no contract.
The full install end-to-end. Five steps, about five minutes from signup to the first answered visitor.
The exact panel and field to paste the snippet on every supported platform. Fasthosts SiteBuilder is highlighted first.
The SmartWidget setup dashboard is where you review and refine the AI receptionist for your Fasthosts SiteBuilder site. The AI reads your site during signup, builds a draft set of question-and-answer pairs, and presents them in the dashboard for review. You edit anything that needs refining, add answers to gaps, set the tone of voice, and configure escalation rules. The dashboard is where the AI is shaped to match your specific Fasthosts SiteBuilder business — services, prices, opening hours, the way you handle out-of-hours enquiries.
Owners of Fasthosts SiteBuilder sites typically spend significant effort getting visitors to the site — SEO, ads, content, social. Then those visitors arrive and have no way to engage in real time. The widget is the missing piece. It engages every visitor instantly, qualifies the enquiry, captures the contact details, and alerts you on SMS the moment a high-intent lead lands. Five-minute install on Fasthosts SiteBuilder. From £19/mo.
Every visitor your Fasthosts SiteBuilder site receives has a conversation that lands in this inbox. Some are auto-handled by the AI in under eight seconds and you never need to look at them — they appear in the Completed tab. Others are escalated to you in real time, with an SMS ping to your mobile. Others again you choose to take over for relationship reasons. The inbox is the operating console for the widget on your Fasthosts SiteBuilder site, and it scales from one site to many.
No. SmartWidget loads asynchronously and isolates its CSS inside a Shadow DOM, so it cannot affect your Fasthosts SiteBuilder theme's styling, animations, or layout. It also does not block page rendering. Lighthouse and PageSpeed scores are unaffected.
Yes for any Fasthosts SiteBuilder plan that lets you paste a script tag or custom JavaScript into Site Editor > Settings > Custom HTML. On a small number of Fasthosts SiteBuilder entry-level tiers the custom code feature is restricted; in that case upgrading to the next plan unlocks it. Most Fasthosts SiteBuilder Business or Pro tiers and above support SmartWidget directly.
No. There is no plugin for Fasthosts SiteBuilder. SmartWidget installs via a single line of JavaScript pasted directly into Site Editor > Settings > Custom HTML. Avoiding the plugin route means fewer dependencies, zero conflicts with your other Fasthosts SiteBuilder extensions, and no plugin marketplace approval process.
A single script tag with your unique widget key. Around 200 characters total. You copy it from the SmartWidget dashboard after signup, paste it into Site Editor > Settings > Custom HTML, and save. The script tag loads our widget client asynchronously when a visitor lands on your page.
No. The widget loads asynchronously after the page has rendered, so it does not block any of your Fasthosts SiteBuilder site's critical rendering path. PageSpeed and Lighthouse scores are unaffected. The widget bundle is under 30 KB and lazy-loads its UI when the visitor first interacts with the chat bubble.
SmartWidget is UK GDPR compliant by design. Conversation transcripts are encrypted at rest in UK-based data centres. The widget includes a configurable consent notice that integrates with most Fasthosts SiteBuilder cookie banner solutions, and the dashboard exposes the controls needed for data-subject access and deletion requests.
Yes. The widget appearance is fully customisable from the SmartWidget dashboard — primary colour, accent colour, chat bubble position (bottom-left, bottom-right), avatar, welcome message, and trigger behaviour. The customisation is centralised, so changing it once updates the widget on your Fasthosts SiteBuilder site immediately.
Remove the single line of JavaScript from Site Editor > Settings > Custom HTML and save. The widget disappears immediately. There is nothing else to uninstall from Fasthosts SiteBuilder — no database tables, no orphaned files, no leftover configuration.
Yes. Multi-site is built in from the Growth tier. One SmartWidget subscription can run widgets across multiple Fasthosts SiteBuilder sites, each with its own AI personality, knowledge base and unified inbox. Particularly useful for agencies running client Fasthosts SiteBuilder sites or operators with multiple brand sites.
Yes. The widget is responsive by default and works on every Fasthosts SiteBuilder mobile breakpoint. The chat bubble sits in the bottom corner on every screen size and the chat interface adapts to mobile-optimised layout when a visitor opens it on a phone.
Yes. The widget integrates with Google Calendar, Outlook (Microsoft Graph), and the built-in SmartWidget scheduler. Visitors browsing your Fasthosts SiteBuilder site can be offered specific appointment slots and book directly inside the chat. The event writes back to your calendar with the conversation transcript attached.
A small number of Fasthosts SiteBuilder entry-level tiers restrict custom code. In that case, upgrading to a tier that allows custom JavaScript is the only path. If Fasthosts SiteBuilder does not allow custom code on any tier, SmartWidget cannot be installed — but this is rare. Almost every modern Fasthosts SiteBuilder Business or Pro plan supports it.
No. SmartWidget operates on monthly billing with no contract and no minimum commitment. Cancel any time directly from the dashboard with no notice period and no exit fee. The lowest tier is £19 per month, billed monthly, so the maximum risk on the decision is a single month's spend.
Live chat support inside the SmartWidget dashboard answers within minutes. The dashboard also contains a step-by-step Fasthosts SiteBuilder-specific install guide with screenshots and the exact menu paths. If the install does not work, support will remote into a screenshare and complete it with you.
4.9 out of 5 from 199 reviews. A selection of install-experience reviews from real UK businesses.
My BigCommerce store has six payment processors and four tracking scripts. I expected another script tag to cause problems. It did not. The widget loads asynchronously and does not block anything on the page.
My GoDaddy site was the third platform we tried — none of the chat tools we previously bought worked on it. SmartWidget installed via the HTML section block in twelve minutes and has been running clean since.
My Strikingly site does not support most chat widgets I tried. SmartWidget installed via the advanced footer HTML field cleanly and the widget appears on every page including the single-page sections.
My BigCommerce store and my WordPress information site needed one chat widget across both. SmartWidget Multi-Site handles both with separate knowledge bases. One subscription, two installs, identical experience.
My Pixieset client gallery site does not support most chat tools. SmartWidget installed via the custom code tracking field with zero modification needed. The widget appears only on the public site, not the client galleries.
My site is on Wix and the developer who built it is no longer around. SmartWidget gave me copy-paste instructions for the Wix custom code section. Live in seven minutes.
