This page is less than a minute
Most windows and doors companies display accreditation logos somewhere on their website.
Far fewer explain why those accreditations should matter to the homeowner.
That is a missed opportunity.
A potential customer may recognise a FENSA, TrustMark, GGF, Secured by Design or BFRC logo without having any idea what protection, reassurance or evidence sits behind it.
Instead of simply placing logos in your website footer, create a substantial Accreditations & Guarantees page that explains each relevant scheme in plain English.
Tell homeowners:
- what the accreditation, membership or certification actually is
- whether your company, installer or product is covered
- what standards have to be met
- whether work is independently checked
- what protection the homeowner receives
- whether it helps demonstrate Building Regulations compliance
- whether guarantees are insurance-backed
- whether the customer can verify your status independently
- and, most importantly, why any of that should make them feel more confident about contacting you
Then link to the relevant section of that page whenever the accreditation logo appears elsewhere on your website.
A logo should not merely say:
“We have this badge.”
It should lead to an explanation that says:
“Here is what this means to you if you trust us with several thousand pounds of work on your home.”
Accreditation logos are valuable only if homeowners understand them
Imagine someone looking for £8,000 or £15,000 worth of replacement windows.
They visit three websites.
All three companies have rows of logos along the bottom of the page.
One says FENSA.
Another says TrustMark.
There may be a BFRC energy-rating logo, perhaps Secured by Design branding, a Glass and Glazing Federation badge and several other icons.
To someone working in the glazing industry, these might all have clear meaning.
To the average homeowner, they may be little more than coloured badges.
They might think:
That looks official.
But that’s considerably weaker than understanding:
This company is regularly assessed for compliance with Building Regulations.
or:
This means my replacement installation is registered with the local authority and I receive evidence of compliance.
or:
This product’s energy performance has been independently assessed rather than simply claimed by the manufacturer.
or:
This security standard involves testing designed to replicate the methods an opportunistic burglar might use.
Those explanations can actively help a homeowner decide who to contact.
The logo on its own often cannot.
Don’t assume homeowners know what FENSA means
FENSA is probably one of the best-known names in the replacement windows and doors industry, but that doesn’t mean homeowners understand what it actually does.
FENSA is a government-authorised Competent Person Scheme for replacement windows and doors. A FENSA Approved Installer can self-certify eligible work against the relevant Building Regulations, and qualifying installations are registered with the local authority. FENSA says its approved installers are assessed regularly.
For the homeowner, the useful message isn’t simply:
FENSA Approved
It’s closer to:
What our FENSA approval means for you
When we complete eligible replacement windows or doors, the installation can be certified through FENSA as meeting the relevant Building Regulations. Your installation is registered with the local authority and you receive a FENSA certificate as evidence of compliance. Eligible FENSA-registered installations also include insurance-backed protection for the installer’s guarantee.
That is meaningful.
It converts an industry logo into consumer reassurance.
FENSA also notes that its scheme doesn’t cover every type of project. For example, new conservatories, new extensions and new-build work fall outside its normal replacement-window and door remit.
That makes accurate wording important.
Don’t imply that a particular accreditation covers work that it doesn’t.
Certass is another Competent Person Scheme – not something every installer also needs
One potential source of confusion on windows and doors websites is presenting every industry name as though companies are expected to hold all of them.
They aren’t.
The UK Government currently lists several authorised Competent Person Schemes capable of covering replacement windows, doors, roof windows and rooflights, including FENSA, Certass, ASSURE, NAPIT and others.
Certass, for example, operates a Competent Person Scheme covering replacement windows, doors, rooflights and roof windows in dwellings and non-dwellings.
For most homeowners, the crucial question isn’t:
Is FENSA better than Certass?
It is:
What does the scheme your installer belongs to mean for my installation and what evidence will I receive?
So if you are Certass certified, explain that.
If you are FENSA approved, explain FENSA.
Don’t clutter an article or website by suggesting good installers somehow need to belong to every alternative scheme.
An Accreditations & Guarantees page should explain each credential separately
For many windows and doors companies, the cleanest website structure would be a single substantial page such as:
/accreditations-guarantees/
or:
/why-choose-us/accreditations-guarantees/
Then create a section for every relevant accreditation, membership, standard or guarantee.
For example:
FENSA
Explanation.
TrustMark
Explanation.
Glass and Glazing Federation
Explanation.
BFRC energy ratings
Explanation.
Secured by Design / PAS 24
Explanation.
Our 10-year product and installation guarantee
Explanation.
Insurance-backed guarantee
Explanation.
You don’t usually need six separate thin content pages.
One detailed page is easier for homeowners to consume and gives you somewhere authoritative to link whenever one of those credentials appears elsewhere on your website.
Use anchor links so every logo can lead to the correct explanation
Suppose your Accreditations & Guarantees page contains:
/accreditations-guarantees/#fensa
and:
/accreditations-guarantees/#trustmark
and:
/accreditations-guarantees/#secured-by-design
Then, wherever the FENSA logo appears on the website, the logo can link directly to:
the FENSA section of your own page
rather than simply dumping the visitor onto FENSA’s website.
That keeps the potential customer on your website while immediately explaining the benefit.
At the bottom of your own explanation, you can then provide an optional external verification link:
Check our FENSA registration on the official FENSA website →
That is much stronger than sending somebody away before you’ve explained why the accreditation matters.
The same principle works with other schemes.
TrustMark: explain the reassurance behind the badge
TrustMark describes itself as the UK’s Government Endorsed Quality Scheme covering work consumers choose to have carried out in and around their homes. It says registered businesses are vetted against required standards and commit to good customer service.
If your windows and doors company is TrustMark registered, don’t settle for:
TrustMark Registered
Explain the significance:
What our TrustMark registration means for you
TrustMark is the Government Endorsed Quality Scheme for work carried out in and around the home. Registered businesses must meet required standards and commit to appropriate customer service and trading practices. Our registration therefore gives you an additional independent source of reassurance when deciding who to trust with your home.
Depending on the route through which the company obtained TrustMark status, there may be additional specific requirements and checks.
For example, FENSA’s published TrustMark requirements include items such as assessment, insurance requirements, complaint procedures and guarantees.
Again, don’t simply copy a scheme’s technical rules.
Translate them into:
What does this mean to the person considering spending money with us?
Glass and Glazing Federation membership: explain the consumer protections
Membership of the Glass and Glazing Federation (GGF) is different from a Competent Person Scheme.
It is an industry federation and membership body.
The GGF states that its membership framework includes its Consumer Code of Practice, Customer Charter and a conciliation scheme for resolving disputes.
A company displaying a GGF logo could therefore explain:
What our GGF membership means for you
As a member of the Glass and Glazing Federation, we operate within an industry framework that includes a Consumer Code of Practice and customer-protection measures. The GGF also provides a conciliation route for resolving disputes. That gives homeowners another layer of confidence that they are dealing with a business committed to recognised industry standards.
The benefit isn’t the logo.
The benefit is the standard, consumer framework and reassurance represented by the logo.
BFRC ratings: turn an energy logo into something homeowners understand
Energy efficiency is one of the major reasons people replace windows.
But claims such as:
Energy efficient
or:
A-rated windows
aren’t as persuasive as independently supported evidence.
The British Fenestration Rating Council (BFRC) provides energy ratings for windows and doors using the familiar A++ to E scale. Its assessment takes account of heat loss, solar gain and air leakage. BFRC says its labels provide independent evidence of product energy performance.
If you sell BFRC-rated products, explain something like:
What the BFRC rating means for you
You can’t tell how energy efficient a window is simply by looking at it. BFRC ratings independently assess the energy performance of a complete window or door system, taking into account heat loss, solar gain and air leakage. The familiar A++ to E scale therefore helps you compare products using independently assessed performance rather than relying solely on marketing claims.
That’s much more compelling than displaying an energy-rating graphic without explanation.
Secured by Design and PAS 24: explain the security benefit, not the acronym
PAS 24 is another phrase that makes perfect sense inside the windows and doors industry but means very little to many homeowners.
Secured by Design explains that current PAS 24 standards set enhanced security-performance requirements for doorsets and windows. The testing is intended to replicate techniques an opportunistic burglar may use with easily concealed tools.
That’s the useful part.
Rather than:
PAS 24 compliant
say:
Enhanced security tested
Our qualifying windows and doors meet PAS 24 enhanced-security requirements. The testing is designed to replicate the type of attack an opportunistic burglar may attempt using tools that can be easily concealed. This provides independent evidence that the product has been designed and tested with security in mind.
That turns technical terminology into a buying benefit.
Also be careful with wording.
PAS 24 is a product/security standard, not an installer accreditation.
Similarly, Secured by Design has specific product and membership criteria.
Don’t casually group everything under “our accreditations” if doing so gives the wrong impression.
A better overall heading can sometimes be:
Accreditations, memberships, product standards and guarantees
That is accurate and still understandable.
Guarantees deserve much more than one sentence
Guarantees are another area where windows and doors companies often waste an enormous conversion opportunity.
A website might simply say:
10-year guarantee
But a homeowner spending thousands of pounds may reasonably wonder:
- What does it cover?
- Glass?
- Frames?
- Hardware?
- Installation workmanship?
- Moving parts?
- Seals?
- How long does each part remain covered?
- Who provides the guarantee?
- What exclusions apply?
- Is it transferable?
- What happens if the installer stops trading?
- Is there insurance-backed protection?
Those questions deserve answers.
The GGF advises consumers to check both the product guarantee and whether it is insurance-backed, and to understand exactly what the guarantee covers.
So instead of:
10-year guarantee
consider:
Our 10-year guarantee
Your new windows and doors are a long-term investment, so we don’t expect you simply to take our word that they’ll perform properly. Our guarantee covers [insert genuine coverage], giving you defined protection should an eligible fault develop. We also explain exactly what is covered before you buy, so there are no surprises afterwards.
Then provide the actual details.
Explain the difference between your own guarantee and an insurance-backed guarantee
These aren’t the same thing.
Your own company may provide a ten-year guarantee.
That guarantee is normally dependent upon your company continuing to trade and being able to honour it.
An insurance-backed guarantee (IBG) is designed to provide specified protection under the relevant policy where the original installer’s guarantee cannot be honoured because the installer has ceased trading, subject to the terms and conditions of the policy.
FENSA states that eligible replacement window and door installations registered through its scheme come with insurance-backed protection for the installer’s guarantee.
That’s extremely relevant to the customer.
Don’t merely write:
Insurance-backed guarantee included.
Explain why:
Additional protection if we’re no longer here
Your installation includes an insurance-backed guarantee, providing additional protection for the qualifying installer guarantee should the installation company cease trading during the applicable insured period, subject to the policy terms.
That communicates an actual benefit.
Don’t overstate guarantee protection
This is particularly important.
Don’t write:
You’re protected whatever happens.
unless that is genuinely what the policy says.
Insurance-backed guarantees have terms, limitations and qualifying conditions.
Likewise, manufacturer warranties, workmanship guarantees and product guarantees can cover different things.
The best marketing is not exaggerated reassurance.
It’s specific reassurance that can be substantiated.
Put the homeowner benefit before the technical detail
A useful rule for every accreditation section is:
Start with the homeowner benefit
Then explain the technical detail.
For example:
FENSA
Benefit first:
Gives you straightforward evidence that qualifying replacement-window and door work complies with the relevant Building Regulations and has been registered appropriately.
Then explain how the scheme operates.
BFRC
Benefit first:
Helps you compare the real energy performance of windows and doors using independently assessed ratings.
Then explain heat loss, solar gain and air leakage.
PAS 24
Benefit first:
Provides evidence that qualifying products have undergone enhanced security testing.
Then explain the standard.
TrustMark
Benefit first:
Provides additional reassurance that you’re using a business operating within a Government Endorsed Quality Scheme.
Then explain registration and vetting.
That order makes far more sense to the homeowner.
Use a repeatable structure for every accreditation
You could make every section on your page follow the same format.
For example:
FENSA Approved Installer
What is FENSA?
One paragraph.
What does this mean for you?
Three to five bullets.
What protection or evidence will you receive?
Clear explanation.
Can you verify our status?
Check our registration →
That same structure could be repeated for GGF, TrustMark, BFRC or anything else.
Consistency makes a complex subject far easier to understand.
Don’t hide accreditations in the footer
The footer is a reasonable place to display accreditation logos.
It shouldn’t be the only place.
Accreditations can help overcome hesitation at exactly the point where somebody is considering contacting you.
Consider showing relevant assurance on:
- your homepage
- windows pages
- doors pages
- conservatory pages
- pricing pages
- Why Choose Us page
- contact page
- quotation/request-a-survey page
- individual case studies
- brochures
- quotation documents
But don’t just repeat unexplained logos.
Where possible, link them to the relevant explanation.
Use visual reassurance bars on product pages
Imagine someone browsing your sash-windows page.
After a section covering pricing or installation you might include:
Choose your installer with confidence
See what our accreditations, independent certifications and guarantees mean for you before making your decision.
See our accreditations & guarantees →
Or:
What protection comes with your new windows?
Understand our guarantees, Building Regulations certification and independent industry credentials.
See how you’re protected →
That is more persuasive than a row of anonymous logos.
Accreditations belong on your Why Choose Us page too
Your Why Choose Us page and your Accreditations & Guarantees page should be closely connected.
The Why Choose Us page can summarise:
Recognised industry credentials
We don’t simply ask you to trust our claims. Our work, products and business practices are supported by relevant independent schemes and standards.
Then:
See what our accreditations mean for you →
That takes people into the full page.
From the Accreditations page, link back:
Accreditations are one of several reasons homeowners choose us. See the other reasons here →
That produces a natural internal-linking relationship.
Your accreditation page can help answer objections before someone enquires
A homeowner may hesitate because they are wondering:
What happens if something goes wrong?
Will my installation comply with Building Regulations?
Will I get paperwork when I sell my home?
Are these windows really as energy efficient as claimed?
How secure is this door?
What if the installer disappears?
Those aren’t SEO questions.
They’re buying questions.
A well-built accreditation page can answer several of them.
And the more uncertainty you remove, the easier it becomes for someone to make contact.
Accreditation information can strengthen individual product pages
Not every accreditation applies equally to every product.
That’s another reason to explain them properly.
On a security-focused front-door page, PAS 24 or relevant Secured by Design evidence may deserve prominent treatment.
On an energy-efficient windows page, BFRC performance could be much more relevant.
On a replacement-window installation page, Competent Person Scheme certification may be particularly important.
Choose the assurance relevant to the product.
Don’t mechanically paste the same row of seven logos onto every page.
Include independent verification wherever possible
One of the strongest things about genuine third-party credentials is that customers don’t have to take your word for them.
Where appropriate, provide a link to:
- your official FENSA listing
- your Certass/consumer listing
- your TrustMark profile
- your GGF membership listing
- relevant certified-product information
The wording could be:
Don’t just take our word for it – verify our membership here.
That turns a claim into evidence.
Distinguish company credentials from product credentials
This deserves its own section because windows and doors websites frequently confuse the two.
For example:
Company/installer-related
- FENSA
- Certass
- TrustMark
- GGF membership
Product/performance-related
- BFRC energy ratings
- PAS 24
- Secured by Design-approved products where applicable
- particular British Standards
Those categories answer different questions.
Company credential:
Can I have confidence in the business or installation process?
Product credential:
Has this particular product/system been independently assessed against a defined standard?
Explain both, but don’t present one as the other.
Don’t collect badges just for marketing purposes
The objective isn’t to accumulate as many logos as possible.
Memberships and schemes cost money and involve administration.
The better question is:
Which schemes genuinely add value to our customers and our business?
Then maximise the value of those you actually hold.
A company with four relevant credentials that it explains superbly may create much more confidence than one displaying fifteen unexplained logos.
Audit every logo currently on your website
Here’s a useful exercise.
Write down every accreditation, membership, quality mark, product certification and guarantee shown anywhere on the website.
Then answer five questions for each one:
- Do we genuinely hold or supply this credential today?
- Exactly what does it cover?
- Why should our customers care?
- Where is it currently explained?
- Can customers independently verify it?
If you can’t answer question three, that’s probably why the logo currently contributes little to website conversion.
Then create your Accreditations & Guarantees page
A good finished page might look something like:
Our accreditations, standards and guarantees
Short introduction about why the company wants customers to understand the protection behind the badges.
FENSA
What it is.
What it means to the homeowner.
What paperwork they receive.
Official verification link.
TrustMark
What it means.
What standards/reassurance sit behind it.
Verification.
Glass and Glazing Federation
Membership explanation.
Consumer Code.
Dispute/conciliation reassurance.
Verification.
BFRC energy ratings
How ratings work.
Why independent energy-performance evidence matters.
PAS 24 / Secured by Design
What security testing means.
Which relevant products meet it.
Our guarantee
Exactly what it covers.
Insurance-backed protection
What that means and its limits.
Then a clear final CTA:
Have questions about the protection that comes with your windows or doors?
Ask us before requesting a quotation. We’re happy to explain exactly what applies to your installation.
Where accreditations fit into the bigger picture
Accreditations are only one part of generating more enquiries. A windows and doors company also needs enough relevant website traffic, extensive examples of completed work, useful pricing information, strong reviews, good contact options and convincing reasons to choose it over competing installers.
See our complete guide to lead generation for windows and doors companies for the wider strategy:
Accreditation doesn’t replace proof of good work
It’s also worth remembering that accreditations alone won’t win every enquiry.
A potential customer may be reassured that you’re properly certified but still want to see:
- installations like the one they’re considering
- genuine customer feedback
- realistic pricing
- photographs of finished jobs
- the people who will work in their home
- strong guarantees
- evidence of aftercare
- reasons to choose you rather than another accredited installer
That’s why accreditation needs to sit within a wider conversion strategy.
Many of your competitors may carry some of the same credentials.
Your advantage comes partly from explaining them more effectively and connecting them with all the other evidence that makes your company credible.
Use accreditation explanations in your brochures too
The same information shouldn’t be confined to your website.
If you’re producing printed brochures, quotations or follow-up packs, create a section such as:
Your protection and peace of mind
Then explain:
- relevant competent-person certification
- guarantees
- insurance-backed protection
- industry memberships
- security standards
- energy ratings
Again, don’t just display logos.
A homeowner sitting at their kitchen table comparing three quotations needs to know why those badges make your proposal safer or more credible.
What should you do next?
If your windows and doors website currently has accreditation logos but very little explanation, the starting point is straightforward.
Step 1: List every current credential
Include memberships, certifications, standards and guarantees.
Step 2: Verify exactly what each one covers
Use the official scheme information, not assumptions or old website wording.
Step 3: Write the homeowner benefit first
For every credential, complete the sentence:
This matters to you because…
If you cannot do that clearly, keep researching.
Step 4: Build one comprehensive page
Use clear sections and anchor links.
Step 5: Link every logo to the relevant section
Don’t make people hunt for the explanation.
Step 6: Add contextual CTAs
Product pages, Why Choose Us, pricing pages and contact areas can all point towards the page.
Step 7: Keep it current
Schemes, standards, your memberships and guarantee arrangements can change.
Review the page periodically.
The key principle
The purpose of accreditation isn’t to decorate your website.
It is to reduce the perceived risk of choosing your company.
A logo saying FENSA, TrustMark or GGF may help.
But an explanation telling the homeowner:
- what was independently assessed
- which standards matter
- what protection they receive
- what paperwork they’ll get
- how guarantees work
- and how they can independently verify your claims
is considerably more powerful.
When you’re asking somebody to spend thousands of pounds improving their home, those details can be part of the difference between:
I’ll keep looking.
and:
These people look trustworthy. I’ll ask them for a quote.
