Window & door marketing agency for UK installers

Window and door marketing that fills your fitters' diaries. Sell the work, not the discount.

On steroids is a window and door marketing agency for UK installers: we film your fitters on real jobs, turn them into Facebook and Instagram ads, qualify every enquiry with a quiz and feed every sale back to Facebook. Double glazing has been sold on "50% off, this week only" for thirty years. Homeowners choose you for the work, not the price.

£2,000 to start, then nothing until your first deal.

A few installers per area. Is yours open?

01The diagnosisWindows · six common symptoms

Sound familiar?

Most installers come to us on one of these. They share one side effect: you can't turn installs up when you need them.

  • 01"Half price, ends Sunday" ads that never end
  • 02Leads who want one back door, fitted tomorrow, for nothing
  • 03Quotes that go to three other companies the same week
  • 04A showroom nobody visits
  • 05Reviews that say "great job" and nothing else
  • 06Fitters with gaps in the diary

Every one of these is fixable, and none of them is your fault. Here's the fix.

02The protocolFive pills · one prescription

Five services. One result: signed installs.

We film your jobs, turn them into ads, qualify every lead, collect the reviews that win the quote, then feed every sale back to Facebook so it finds more buyers.

New to windows. Not new to selling installs.

The same team, videos and Facebook system has sold £27.2M from our Facebook ads for our installers, mostly in solar. These are the live figures across all of them, read from their own CRMs; window and door figures get their own line once there are enough to be meaningful.

Why now · early movers

Get in before your area fills.

We take a few window and door installers per area, and the first ones in get our full attention while the trade is new. In Ireland, Activ8 were first in with our approach and made 400% more sales than with their old agency, from our Facebook ads.

05Leads, explained

Need more window and door leads? Make sure they turn into fitted jobs.

We don't sell leads. Read what bought window & door leads really cost per install, and what we do instead.

Patient questions.

The ones we get on every first call, answered straight.

Every question →
  • Q01

    Do you work with window and door installers already?

    Yes. We started with window and door installers in 2026: same filming days, same team, same system that sells solar.

  • Q02

    Is my area exclusive?

    No, we don't do area exclusivity, and we won't pretend otherwise. What you do get: every lead is yours alone, never shared, and we cap numbers so our ads never fight each other for the same homeowners. Solar is capped at 60 installers UK-wide; every other trade at a few per area.

  • Q03

    What's a good cost per lead for windows and doors?

    The one that turns into fitted jobs. A cheap lead who wants one back door for nothing costs more than a dearer one who signs. Judge it by cost per sale: we track every lead to the sale in your CRM, so you see what each fitted job cost.

  • Q04

    Do you run discount ads?

    Rarely. Offers bring price-shoppers. We sell your fitting, your products and your reviews.

  • Q05

    Can I leave?

    Monthly rolling, 30 days' notice. You keep everything we film.

  • Q06

    What is the minimum ad spend?

    £2,000 / month. You pay it to Meta directly, on your own ad account, never through us. Our fees are separate.

  • Q07

    What does it cost?

    It's £2,000 + VAT to start. Your ad spend is separate: you pay it to Facebook directly, from your own ad account, so you see every penny. Ben runs through the rest for your trade and your area on the call.

  • Q08

    I've tried Facebook ads. They didn't work.

    Most installers we talk to have. Usually it was stock footage, a lead form anyone could tap, and nobody telling Facebook who bought. We change all three: your real jobs on video, a quiz first, and every sale fed back. And there's no retainer until your first deal, so you're not paying to find out.

  • Q09

    Do you sell window leads?

    No. A bought lead is sold to three or four installers the same afternoon; yours are yours alone, from your own ads. The maths is on our window and door leads page.

We're taking a few window and door installers per area. Be first in yours.

Five quick questions, then pick a time with Ben. Thirty minutes on where you're losing sales, and what we'd run instead.

£2,000 to start, then nothing until your first deal.
