Free Marketing for a UK Window and Door Installer

Last Updated on September 8, 2026

This trade has something most home improvement trades do not: a certificate the customer will need again years later, at the worst possible moment, when they sell the house. Almost nobody markets on it.

The resale paragraph

Here is the sequence. Your customer sells their house eight years from now. The buyer’s conveyancer asks for evidence that the windows meet Building Regulations. The seller cannot find the certificate. The sale stalls while somebody works out whether an indemnity policy or a retrospective application is needed.

Two hundred words on your website explaining that, and explaining that FENSA charges £30 including VAT for a replacement copy and that the compliance certificate can be found by address and postcode, is the most useful thing on most glazing sites. It costs an hour.

It also does something subtler. It reframes the quote comparison. A customer weighing your price against an unregistered installer’s cheaper one is not comparing windows. They are comparing a job that will survive a conveyancing search against one that will not.

The three records that must agree

Companies House, your website, your Google Business Profile. Same trading name, same address, same phone number.

In Whito’s July 2026 study, 30 per cent of 64 tradespeople found by ordinary search could not be verified as an active company at Companies House, including two trading under a dissolved one. In a trade where the customer is handing over a deposit on several thousand pounds of made-to-measure product, that is the cheapest reassurance available and it costs nothing.

The zero-pound weekend, glazing version

1. Make the three records agree.
2. Put your competent person scheme name and registration number on the site, as text, with a link to the scheme.
3. Write the resale paragraph. What the certificate is, when it matters, how to get a copy.
4. Add one sentence saying your scheme issues a Building Regulations Compliance Certificate and that this is the same document people mean by FENSA certificate.
5. Correct the certificate cost on your own page: the notification fee is £2.05 excluding VAT per installation, not £25 per window.
6. Publish one worked house: window count, product, scaffolding, waste, making good, days on site, total.
7. Ask your last ten customers for a review that names the property type and the town.

Item five deserves comment. Checkatrade’s window fitting guide states that a FENSA certificate adds £25 per window. FENSA’s own published fee schedule puts the notification fee at £2.05 excluding VAT per installation. Correcting a national guide’s error on your own page, with the source and the date, is a small generous act that makes everything else you say more credible.

What to photograph

Every glazing website shows a finished window. That photograph is worthless because every finished window looks the same.

• The old frame out and the aperture clean and square.
• Trickle vents and the drainage path, which most customers have never seen.
• Making good, inside and out, on a difficult reveal.
• The site protected: dust sheets, floor protection, an occupied house still usable.
• The certificate itself, or the notification confirmation.

The last one is unusual and worth doing. It makes the compliance argument concrete rather than abstract.

The lead economics you can actually know

One useful asymmetry in this trade: MyBuilder publishes its lead prices and gives glazing examples. Its shortlist fees range from £2 to £35 depending on job size, with no joining or membership fee, and it publishes worked examples including repair window handles at £4.90 and new porch and bay window block work at £21.00.

Checkatrade publishes plan prices, a free tier, Approved at £30 a month and Growth from £59 a month on twelve-month terms, but does not publish the lead economics. Bark publishes neither in pounds; the only figure on its help page is 2.35 US dollars per credit, and we are not converting that.

So for a window installer, MyBuilder’s cost per opportunity is knowable in advance and the other two are not. That is a reason to run a measured trial there before anywhere else, not because it is better, but because you will be able to tell.

Common questions

What is the single highest-value free thing to add to a glazing website?

The resale paragraph, explaining what the compliance certificate is and when the customer will need it again. It is the only argument in this trade that a cheaper unregistered quote cannot answer.

Should I put my scheme logo on the site?

Put the scheme name and your registration number as text, then the logo if you like. A machine cannot read a JPEG, and the registration number is the part a careful customer can check.

Is it worth joining a lead platform?

Run one trial, on the platform that publishes its lead prices, and log which leads became jobs for ninety days before renewing anything. In a trade with made-to-measure product and long lead times, the platform that lets you compute cost per won job is worth more than the one with the bigger promise.
