Your portal

Everything installers told us was broken, fixed in one place

They told us: not enough work booked in. Now their portal shows: appointment booked. Never knew when the next job was coming. Now there's a goal. Hit it, hire the next team. They told us: too many wasted journeys. Now they see the job the second it's booked. They told us: leads never pick up. So we contact them within 30 seconds. Now they pick up when you ring, and they're there when you arrive. They told us: our socials look dead. Now they send us their jobs, we turn them into posts. They told us: happy customers never review. Now we send a link, they film a video review.

Questions installers ask

What does it cost all-in?

Your monthly plan, plus your ad spend, which you pay straight to Meta from your own card. There's a one-off setup fee, set on the call to suit your area and size. You see your plan's monthly price before you book.

How long am I tied in?

Two months to start, so the ads have time to bed in. Booked or Back covers you from the first appointment. After that it's month to month.

What if the leads are rubbish?

You're not paying for leads. Your plan includes sat appointments, and that's what our promise covers. We call it Booked or Back: money back for every sat appointment we miss, £100 on Growth, £75 on Scale. It's not a refund on our fee. It's money back on the thing you're paying for: appointments in your diary. Greencastle sold 56 jobs from the 157 appointments that went ahead. That's better than 1 in 3.

Who does the selling?

You do, the same as now. We fill the diary with homeowners who've booked an appointment. You go out and sell.

How is this different from lead sites?

Lead sites often sell the same enquiry to several firms. Your ads run in your company's name, the enquiries are yours alone, and we book them in for you.

I take every one of these calls myself. We also run a separate programme for window and door manufacturers, so we know what a unit costs and how the trade works. We'll go through your numbers, your area and what your first month would look like. If it's not a fit, I'll tell you.
