Your design consultants are expensive. Send them to real buyers.
A glazed extension or single-storey build is one of the biggest things a homeowner will spend on their house. The journey runs for months. We find the serious ones, book design visits with people who have the budget, and keep every project warm through planning and decision time.
A buyer who daydreams for a year, then decides in a week.
The homeowner thinking about an orangery has usually been thinking about it for a long time. They save pictures, visit a show home, talk to friends who built one. Then a trigger arrives: a bonus, a baby on the way, a decision not to move. Suddenly they want three designers round within a fortnight.
If you are not already in front of them when that switch flips, you are one of six names on a comparison site. And when you do get the visit, you are sending a senior designer for two hours, sometimes with a home presentation and a 3D drawing to follow. That is costly time for an enquiry that might be someone pricing a dream.
The cycle also has hurdles a window fitter never sees. Is it permitted development or does it need a full planning application? Does a solid roof or a lantern change the building regulations picture? Will the neighbours object to a larger rear extension? Every one of those questions adds weeks, and every pause is a chance for the customer to go cold or go elsewhere.
What costs extension firms the most
- Design visits to people with no budget. The dream is a large orangery with bi-folds. The budget is a lean-to.
- Long gaps with no contact. Planning, finance decisions and family debate stretch out for months while your quote sits in a drawer.
- One partner at the visit. The other one sees the price that evening and says no.
- Unworked old quotes. Hundreds of past design visits that never converted, with nobody asking whether now is the time.
Priced to the project, not a generic rate card.
A lean-to conservatory and a large kitchen extension are not the same lead. For this trade we agree pricing per campaign, based on the criteria you set. As a guide, our trade pricing starts from £20 per certified lead and £130 per booked appointment, ex VAT, and tighter criteria on budget and project size cost more.

- Both decision makers asked to be present
- Booked into the design slots you release
- Confirmation plus reminders before the visit
- Replaced if outside agreed criteria, reported within 72 hours
Patience at scale.
Your best salespeople cannot personally keep 200 open projects warm for nine months. AI can, and it hands each one back to a human the moment they are ready to talk.
Instant response
VoiceAI calls every new enquiry within moments, answers in under three rings when they call you, and books the design visit while interest is high.
Pre-visit prep
Automated messages ask for photos of the back of the house and garden, so your designer arrives prepared.
Long-cycle nurture
Scheduled check-ins through planning and decision time, with replies and objections logged in your CRM.
Quote reactivation
AI calls or messages past design visits that never signed and asks if the project is back on. A warm restart often costs less than a new lead.
A chatbot for the early researchers
Conservatory or orangery? Will I need planning? How long does a build take? A website and WhatsApp agent answers from your approved information, makes clear when planning advice depends on the property, and captures the enquiry with budget and timescale.
Joined-up systems
Enquiries, design notes, drawings, planning dates and finance status in one place. We integrate with CRMs such as HubSpot, Salesforce and Zoho, project tools like Monday.com, and your email and calendars. More on integration →
Managed AI agents from £497 per month. Custom automation projects from £2,500. Typical delivery one to three weeks.
One extra signed project changes the maths.
With project values that often run into tens of thousands of pounds, a small change in conversion matters far more than the cost of a lead. The figures below are invented for illustration and are not a client result.
| Without nurture | With qualification and nurture | |
|---|---|---|
| Design visits booked in a quarter | 30 at £200 = £6,000 | 30 at £200 = £6,000 |
| Visits with budget confirmed beforehand | Unknown | All 30 |
| Projects signed | 3 | 5 |
| Appointment cost per signed project | £2,000 | £1,200 |
Set that against your contribution on a typical project and the question changes from "how cheap is the lead?" to "how many projects do we lose for lack of follow-up?" That is the question we start with.
No promises your designer has to unpick.
Many single-storey rear additions in England can fall under permitted development within set size limits, and larger rear extensions may be possible through a prior approval process. But conservation areas, Article 4 directions, listed buildings and previous extensions all change the answer. Our ads and AI never tell a homeowner they will not need planning. That is your call, after a proper look.
Consent recorded on every lead. Calls and messages only where UK GDPR and PECR permit, TPS screening where required, and AI disclosure at the start of every VoiceAI call.
Questions from conservatory and extension firms.
Why is pricing agreed per campaign rather than a fixed rate?
Because a small lean-to and a large orangery are very different leads. Pricing depends on project type, minimum budget and region. Our trade pricing starts from £20 per certified lead and £130 per booked appointment, and we agree the exact figure with you before anything goes live.
Can you set a minimum budget for design visits?
Yes. VoiceAI asks about budget on every appointment and only books homeowners within the band you set. If a booked visit falls outside it, report it within 72 hours and we replace it.
Will you tell homeowners they do not need planning permission?
No. Whether a project needs planning depends on the property, location and any previous extensions. Our messaging stays general and leaves that judgement to your designers.
Can you get both decision makers at the design visit?
We ask for it on every booking and record who will attend. We cannot force it, but asking up front noticeably reduces the "I need to talk to my partner" stall.
Do you only generate glazed extension leads?
No. We can run campaigns for conservatories, orangeries, conservatory roof replacements and single-storey extensions. Tell us what you build and we shape the criteria around it.
Can AI follow up on quotes that are months old?
Yes. Reactivation of old quotes is often one of the best-value things we do for this trade. VoiceAI or SMS contacts past prospects, asks whether the project is still on, and books a fresh visit or updates your CRM.
Are the leads exclusive?
Yes. Every certified lead and booked appointment is yours alone.
