A double glazing lead is a homeowner enquiry for new windows, doors or a conservatory quote. In the UK, exclusive real time leads start from around £15 per lead, with prices rising for higher-value products like conservatory roofs and falling for shared or lower-quality enquiries. Installers should judge a provider on whether the lead is exclusive, how it was generated, what information it comes with, and how fast it is delivered. This guide covers all of that.
What a double glazing lead actually is
A double glazing lead is a homeowner who has asked for a quote on windows, doors, a conservatory, or conservatory insulation and roofing. It should come with the product they are interested in, their property type, and enough detail to prioritise a call. A genuine lead is not a name pulled from a database, and it is not someone cold-called and asked if they'd like a quote - it is someone who actively requested one.
Where double glazing leads come from
- Own comparison websites, Google Ads, paid social and directories or shared marketplaces are the four places a double glazing lead can come from.
- What the homeowner was asked before the enquiry was submitted is what decides its quality.
- That enquiry is the lead you buy.
- Own comparison websites, where a homeowner compares window or door quotes and submits their details.
- Google Ads, where a search like "double glazing quotes near me" leads to a form.
- Paid social on Facebook, Instagram and TikTok, prompting a homeowner to request a quote.
- Directories and shared marketplaces, including trade directory listings, where several installers can access the same enquiry.
The first two channels, run by a provider that owns its own websites and landing pages, tend to produce the highest-intent, most recent enquiries. Directory and marketplace leads vary widely in freshness and exclusivity.
Exclusive versus shared double glazing leads
An exclusive lead is sold to one installer only. A shared lead is sold to several installers at once, usually for a lower price, but the homeowner ends up fielding calls from multiple companies and often goes with whoever calls first or offers the lowest quote on the phone. If you install a higher-value product such as conservatory roofs, the cost of losing a job to a faster competitor on a shared lead usually outweighs the saving on the lead price itself.
Real time versus aged leads
Real time leads reach you within seconds or minutes of submission. Aged leads are days or weeks old, typically sold cheaply in bulk for outbound calling. Double glazing is a considered purchase where the homeowner is usually comparing two or three companies, so speed of delivery and speed of your own follow-up both matter. Contacting a new lead within five minutes gives you the best chance of winning the job before a competitor gets there first.
What a genuine double glazing lead should contain
Look for these fields as standard:
- Full name and a checked UK phone number
- Property postcode
- Product interest (windows, doors, conservatory, conservatory roof or insulation)
- Property type (house, bungalow, flat) and whether the homeowner owns the property
- Rough budget or number of windows/doors, if captured
- Source and timestamp of the enquiry, with confirmation of consent
What double glazing leads cost and why prices vary
UK double glazing leads start from around £15 per lead for windows and doors, rising for higher-value products such as conservatory roofs (from around £30) and conservatory insulation (from around £22). Price is driven by exclusivity, volume, area and the specific product. Some providers also offer pay-per-appointment, where the enquiry is qualified and a home visit booked directly into your diary for a higher fee per appointment than per lead, and revenue share arrangements for installers who prefer to pay as a percentage of sales.
Double glazing lead sources compared
| Source | Exclusivity | Speed | Typical price signal | Watch for |
|---|---|---|---|---|
| Own comparison websites | Usually exclusive | Real time | Mid to higher | Confirm the provider owns the site and landing page |
| Google Ads and paid social, run direct | Exclusive | Real time | Mid to higher | Ask what qualifying questions are asked before the form |
| Trade directories | Often shared | Real time to same-day | Lower | Multiple installers may already be calling |
| Shared marketplaces and aged data | Shared, sometimes resold | Delayed | Lowest | Lowest contact rate and highest risk of stale consent |
How to judge double glazing lead quality in the first two weeks
- Contact rate: what share of double glazing leads you actually reached.
- Appointment rate: Booked, and attended?
- Rejection rate: how many were replaced under the rejection policy.
Track contact rate, appointment booking rate and rejection rate from the first batch. A provider should offer a rejection policy so a wrong number, duplicate or clearly non-genuine enquiry is replaced rather than charged. If your appointment attendance rate is low, check how the appointment was booked and by whom - a lead qualified and booked by the provider's own team should attend at a materially higher rate than a raw web lead you have to chase yourself.
Contact rate and follow-up practice
Route every double glazing lead to a salesperson's phone immediately and call within five minutes. If the call is missed, follow up with a text and email within the hour. Installers using CRM tools to automate this first step consistently convert more enquiries into home surveys than those relying on manual follow-up.
Pay per lead, pay per appointment or revenue share
Most UK double glazing lead providers offer more than one commercial model, and which one suits you depends on the size of your sales team. Pay per lead puts the qualifying and follow-up work on you, at the lowest price per enquiry. Pay per appointment costs more per unit but hands you a home visit already booked into the diary by the provider's own team, which suits businesses without spare capacity to chase raw leads. Some providers also offer revenue share, where you pay a percentage of the value of jobs won rather than a fixed fee per lead, which shifts risk onto the provider but usually means a longer-term relationship rather than a simple pay-as-you-go arrangement. None of these should come with a long-term contract; if a provider insists on one to access their better-converting model, that is worth questioning.
How to switch double glazing lead providers without a coverage gap
If you are moving from one provider to another, run both for a short overlap period rather than switching off the old one before the new one is proven. Agree a trial volume with the new provider, ideally over two to four weeks, before committing to your full weekly volume. Ask what happens to leads already in your CRM from the old provider, and make sure your sales team knows which leads came from which source so follow-up speed and quality can be compared fairly rather than blamed on the wrong campaign.
Red flags when choosing a double glazing lead provider
Be wary of providers who will not confirm exclusivity in writing, who cannot say where the lead was generated, who have no rejection policy, or who lean on "free lead" offers as the main pitch rather than lead quality. Confirm the provider runs campaigns in line with ASA and ICO rules, since window and door advertising claims are a regulated area, and check they will name the areas and postcodes they can cover before you commit any spend.
