Window fitter website design: beating the nationals

Since 2002, every replacement window fitted in England and Wales has counted as notifiable building work, which means it has to be certified either by the local council or by an installer registered with a competent person scheme. Almost no homeowner thinks about that when they are getting quotes. All of them think about it years later, on the day their buyer's solicitor asks for the paperwork and nobody can find it. That gap, between what the customer is worrying about now and what will actually cost them money later, is the most useful thing a local window fitter's website can occupy. The national double glazing firms will not go near it, because their entire sale is built on the appointment. A UK installer with a clear site can answer it in one paragraph and look like the only grown-up in the search results.

The national sales pitch is your biggest advantage

The national firms have spent decades teaching British homeowners to dread the double glazing sales process, which means a local installer does not have to win on price, only on the absence of that experience.

Ask anybody who has replaced windows what the worst part was. It is almost never the fitting. It is the evening appointment that ran to three hours, the manager who was phoned for a special discount, the price that halved when they stood up to leave. That reputation is not yours, but you inherit the suspicion it created, and you can also inherit the relief when a customer realises you work differently.

The point is not to slag off the competition on your own website, which reads badly and always has. The point is to describe your own process in enough specific detail that the contrast makes itself. "I measure in about twenty minutes and email a written quote within three working days, and it does not expire" does more damage to a national's pitch than a paragraph of complaining ever would.

Put your scheme number where it can be checked

Registration with a competent person scheme is the one credential in this trade that a customer can verify themselves in under a minute, which makes hiding it in a footer logo a genuine waste.

Replacement windows and doors are covered by the Building Regulations, and the government's own guidance sets out that using a registered competent person removes the need for a separate building control application (GOV.UK, building regulations approval). FENSA, the largest of these schemes in England and Wales, issues the certificate the homeowner later needs, and lets anyone look up a certificate or an installer (FENSA). A logo proves nothing. A number proves you.

There is a second reason to lead with this. A homeowner who has understood the certificate now has a question to ask every other quoting installer, and a fair number of them will fumble it. You have handed them the test and you are the only one who has already passed. The wider principle, that verifiable facts beat adjectives on every trade site, is worked through in whether you actually own your trade website.

Publish a band, because the nationals never will

The single most requested thing missing from window installer websites is any indication of price, and the firms who refuse to give one are the same firms customers already distrust.

You cannot price a house off a webpage. Frame material, glazing specification, how many openers, whether there is scaffolding, whether the reveals are sound: all of it moves the number. None of that stops you publishing a range per style with a short note on what pushes a job to the top of it. A customer who can place themselves before ringing arrives at the measure already roughly agreeing with you, which is a completely different conversation from one where the number is a surprise.

There is a fear underneath the silence, and it is worth naming: that publishing a range means being undercut by somebody cheaper. In practice the opposite happens. A band filters, and what it filters out is the enquiry that was always going to go elsewhere on price, which is the enquiry that costs you an evening and a tank of diesel before it says no. The installers who quote all week and book one in six are usually the ones whose website told a caller nothing at all.

Show the house, not the window

A gallery of individual white frames proves nothing, because every window looks like every other window, while one whole elevation shown before and after proves the thing a customer is actually buying.

Windows are the rare trade where the product is nearly identical across every installer on the street. What differs is the fit, the finish round the reveals, the making good, and whether the house looks better afterwards. None of that is visible in a close-up of a frame. All of it is visible in a photograph of the front of the house taken from the pavement, before and after, from the same spot.

Shoot the elevation, not the unit. Include the property so somebody with a similar house can recognise their own. A 1930s semi, a stone cottage, a new-build with grey aluminium: those are the searches people are really running in their heads, and a gallery organised by property type will out-convert one organised by product range every time. The practical habits for getting those shots on a phone are in how to photograph your own work.

Quote faster than they can book an appointment

Speed is the one thing a two-person local firm can beat a national at without spending a penny, and on windows it is worth more than it is on almost any other trade.

The national process has a built-in delay: book the appointment, sit the appointment, wait for the paperwork. If your site says you measure within the week and email a written quote within three working days of that, you have won on the only axis where being small is an outright advantage. Put the timescale on the page as a commitment, not a hope, and then keep it.

The same discipline applies to the enquiry itself. A form that asks for the property type, roughly how many windows and a photo of the front of the house lets you give a meaningful indication before anybody drives anywhere. Doors are worth a separate page for the same reason: a composite front door is a different purchase from eleven windows, bought by a different customer on a different timescale, and burying it inside a windows page loses the search entirely. The equivalent split for high-value fitting work is covered in bathroom fitter and tiler website design.

What actually converts a window enquiry

Window work is compared over weeks and decided on the second or third visit to your site, usually by two people at a kitchen table, so the page has to still answer questions a fortnight after the first look.

The first visit is a filter: do they cover us, do they look real, is there a price. The later visits are the decision, and by then the questions have got specific. What is the guarantee. Who fits them, you or subcontractors. What happens about the plastering round the reveals. How long will the house be open. Those answers belong on the site, not saved for the doorstep, because the people asking them are comparing you against two other quotes in a spreadsheet.

That is exactly the kind of site I build, starting with a free mockup of your actual business using your own jobs, before you pay anything. A one-off £600 to build (£300 to start, £300 when you approve it), then £20 a month for hosting, security, renewals and unlimited small edits, cancellable any time. Sites are usually live in about a week. On a trade where a single won job covers the whole thing several times over, the arithmetic is not difficult.
