UK homeowners lose an estimated \u00a315 million every year to rogue traders in the home improvement sector. This guide shows you exactly how to vet a fitter, what questions to ask, what to watch out for, and what to put in writing before you sign anything.<\/p>\n\n\n\n<div class=\"wp-block-group has-background\" style=\"border-left-color:#10B981;border-left-width:4px;border-radius:12px;background-color:#F8FAFC;margin-top:24px;margin-bottom:24px;padding:24px\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n\n<h3 class=\"wp-block-heading\" style=\"margin-top:0;margin-bottom:12px\">\ud83d\udd0e TL;DR \u2014 vetting a double glazing fitter in 8 steps<\/h3>\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Get 3\u20134 quotes minimum<\/strong> \u2014 spread between highest and lowest is typically \u00a32,000\u2013\u00a34,000<\/li>\n<li><strong>Only consider FENSA, Certass, or Trustmark registered<\/strong> fitters \u2014 verify on their official databases<\/li>\n<li><strong>Check Companies House<\/strong> \u2014 avoid fitters trading under shell companies<\/li>\n<li><strong>Read recent Google + Trustpilot reviews<\/strong> \u2014 look for detail, not just stars<\/li>\n<li><strong>Never sign on the first visit<\/strong> \u2014 any legitimate quote is valid for 14\u201330 days<\/li>\n<li><strong>Avoid cash-only demands<\/strong> \u2014 pay by card or bank transfer for chargeback protection<\/li>\n<li><strong>Local installers<\/strong> are typically 20\u201340% cheaper than national chains for the same spec<\/li>\n<li><strong>Get everything in writing<\/strong> \u2014 verbal promises don&#8217;t count<\/li>\n<\/ul>\n\n<\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Why the fitter matters more than the windows<\/h2>\n\n\n\n<p>Two identical uPVC windows installed by different fitters can have completely different outcomes 10 years later. A poorly-installed window leaks, causes damp, loses its seal, and needs replacing within a decade. A properly-installed one lasts 30 years with no issues. The material is commodity \u2014 the craft is in the installation.<\/p>\n\n\n\n<p>This is why FENSA and Certass certification exist. They&#8217;re the UK&#8217;s self-regulatory schemes for installers \u2014 and a fitter without at least one of these is not someone you should hire. Period.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The 10 red flags of a rogue fitter<\/h2>\n\n\n\n<p>Any ONE of these should make you pause. Two or more \u2014 walk away.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Mobile phone only \u2014 no fixed business address<\/h3>\n\n\n<p>Every legitimate UK installer has a registered office address you can verify on Companies House. A contact on a 07-prefix mobile with no address is usually a one-person operation with no insurance, no warranty protection, and no accountability if the job goes wrong.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. No FENSA, Certass, or Trustmark registration<\/h3>\n\n\n<p>These aren&#8217;t optional. UK building regulations require replacement window installations to be notified to the local council \u2014 FENSA-registered fitters do this automatically and issue a certificate. Without it, you have no proof of compliance, which can invalidate your home insurance and cause issues when you sell.<\/p>\n\n\n<p>Verify credentials directly:<\/p>\n\n\n<ul class=\"wp-block-list\">\n<li>FENSA: <a href=\"https:\/\/www.fensa.org.uk\/find-an-installer\" target=\"_blank\" rel=\"noopener\">fensa.org.uk<\/a><\/li>\n<li>Certass: <a href=\"https:\/\/www.certass.co.uk\/find-a-certass-installer\" target=\"_blank\" rel=\"noopener\">certass.co.uk<\/a><\/li>\n<li>Trustmark: <a href=\"https:\/\/www.trustmark.org.uk\/find-a-tradesman\" target=\"_blank\" rel=\"noopener\">trustmark.org.uk<\/a><\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. Cash-only payment demands<\/h3>\n\n\n<p>Pay by debit\/credit card or bank transfer. Cash has zero chargeback protection \u2014 if the fitter vanishes, your money is gone. Credit cards give you Section 75 protection for amounts over \u00a3100, meaning the card issuer is jointly liable if the service isn&#8217;t delivered.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Pressure to &#8220;sign today&#8221; for a special price<\/h3>\n\n\n<p>This is the #1 trick of high-pressure sales visits. &#8220;Manager call-in discount&#8221;, &#8220;showroom offer&#8221;, &#8220;board price&#8221; \u2014 all designed to stop you getting competing quotes. A real price is valid for 14\u201330 days. If it expires at 8pm tonight, it was never a real price.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Quotes with no itemised breakdown<\/h3>\n\n\n<p>A legitimate quote must itemise: product cost, frame material, glass spec, scaffolding, removal + disposal, VAT, warranty period, and installation labour. &#8220;Total: \u00a36,400&#8221; on a single line with no breakdown is a red flag for hidden costs or deliberate vagueness.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Reviews that feel too polished<\/h3>\n\n\n<p>Check for: specific customer names (first name + surname initial), location details, date ranges, and mentions of specific products. Fake reviews are usually short, too effusive (&#8220;5 stars, amazing!&#8221;), and cluster in short date windows. Real reviews include complaints about minor issues, which actually increases trust.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. No insurance-backed warranty<\/h3>\n\n\n<p>FENSA and Certass provide insurance-backed guarantees \u2014 so if the installer goes out of business, your warranty is still honoured by the scheme. Without this, a &#8220;10-year guarantee&#8221; is worthless the moment the company closes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">8. Vague about product specifications<\/h3>\n\n\n<p>You should know: the frame supplier brand (Rehau, Deceuninck, Veka, Eurocell are common reputable UK suppliers), the energy rating (A++ \/ A+ \/ A), the glass type (argon-filled, low-e coating, toughened where required), and the locking mechanism (PAS 24 certified is the security standard).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">9. No physical showroom or office<\/h3>\n\n\n<p>You can&#8217;t check physical showroom photos on Google Images or pop in to see actual samples. A serious installer has a showroom or at least a trade counter where you can inspect the actual frames before ordering.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">10. Shell companies with no trading history<\/h3>\n\n\n<p>Check <a href=\"https:\/\/find-and-update.company-information.service.gov.uk\" target=\"_blank\" rel=\"noopener\">Companies House<\/a> \u2014 free public database. Look at: incorporation date (avoid companies under 2 years old for a \u00a310k job), filed accounts (shows financial stability), and director names (cross-check against struck-off company databases for patterns).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to verify an installer is legitimate \u2014 5-minute checklist<\/h2>\n\n\n\n<p>Before any quote visit, spend 5 minutes doing this:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Check FENSA<\/strong>: enter the company name at fensa.org.uk \u2014 should show active registration, number, and coverage area.<\/li>\n<li><strong>Check Certass<\/strong> if not FENSA: certass.co.uk has the same lookup.<\/li>\n<li><strong>Companies House search<\/strong>: find the company, verify age, directors, filed accounts.<\/li>\n<li><strong>Google the company name + &#8220;reviews&#8221;<\/strong>: look at Google Business profile (unverified companies don&#8217;t have one), Trustpilot, Facebook reviews.<\/li>\n<li><strong>Google the directors&#8217; names<\/strong>: look for any ties to previously liquidated companies. Rogue traders often change company names to avoid bad reviews.<\/li>\n<li><strong>Ask for local references<\/strong>: any legitimate installer should give you 2\u20133 recent customers in your area you can call.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">National chains vs local installers: which is better?<\/h2>\n\n\n\n<p>This is the biggest money-saving decision you&#8217;ll make. Here&#8217;s the real trade-off:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table>\n<thead><tr><th>Factor<\/th><th>National chains<br>(Anglian, Everest, Safestyle)<\/th><th>Local FENSA fitters<\/th><\/tr><\/thead>\n<tbody>\n<tr><td><strong>Typical price<\/strong><\/td><td>\u00a36,000\u2013\u00a312,000 full house<\/td><td>\u00a34,000\u2013\u00a39,000 same spec (20\u201340% less)<\/td><\/tr>\n<tr><td><strong>Marketing overhead<\/strong><\/td><td>\u00a3500\u2013\u00a31,500 per sale (TV, direct mail)<\/td><td>Near zero \u2014 baked into price<\/td><\/tr>\n<tr><td><strong>Sales approach<\/strong><\/td><td>Commission-based reps, high pressure<\/td><td>Owner-led, direct, no pressure<\/td><\/tr>\n<tr><td><strong>Product quality<\/strong><\/td><td>Often branded frames from same UK suppliers<\/td><td>Often identical suppliers (Rehau, Deceuninck, etc.)<\/td><\/tr>\n<tr><td><strong>Installation quality<\/strong><\/td><td>Subcontracted \u2014 varies by who they send<\/td><td>Usually the owner + 1-2 long-term staff<\/td><\/tr>\n<tr><td><strong>Warranty<\/strong><\/td><td>10-year insurance-backed via FENSA<\/td><td>Same 10-year insurance-backed via FENSA<\/td><\/tr>\n<tr><td><strong>Aftercare<\/strong><\/td><td>Mixed \u2014 contact centres<\/td><td>Direct line to the fitter who did your job<\/td><\/tr>\n<tr><td><strong>Finance options<\/strong><\/td><td>Strong \u2014 0% finance widely available<\/td><td>Variable \u2014 ask upfront<\/td><\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n<p><strong>Verdict<\/strong>: for most UK homeowners, a well-vetted local FENSA installer is the better choice \u2014 you get the same quality product for less money, and better aftercare. <a href=\"\/glazing\/index.php\/quote\/\">Get 4 quotes mixing local + national<\/a> and let the price gap speak for itself.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">15 questions to ask during the sales visit<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">About the company<\/h3>\n\n\n<ul class=\"wp-block-list\">\n<li>Are you FENSA or Certass registered?

Standardise before you compare:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Define one spec you want<\/strong> first \u2014 e.g., &#8220;uPVC, A-rated, Rehau frames, argon-filled, PAS 24&#8221;<\/li>\n<li><strong>Ask every installer to quote against that spec exactly<\/strong> \u2014 no upselling, no downgrading<\/li>\n<li><strong>Compare the totals<\/strong> on the same spec, not on different specs<\/li>\n<li><strong>Then compare their recommended upgrades<\/strong> \u2014 A++ vs A-rated, laminated glass, etc. \u2014 separately<\/li>\n<\/ol>\n\n\n\n<p>This method typically reveals a \u00a32,000\u2013\u00a34,000 spread between the cheapest and most expensive quote for identical work \u2014 and helps you negotiate.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How many quotes should you get?<\/h2>\n\n\n\n<p>Minimum 3, ideally 4. Here&#8217;s why:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1 quote: you have no reference point at all \u2014 you&#8217;ll almost certainly overpay<\/li>\n<li>2 quotes: you can tell if the first was inflated, but can&#8217;t tell which is fair<\/li>\n<li>3 quotes: clear triangle \u2014 you can spot outliers on both sides<\/li>\n<li>4 quotes: diminishing returns but still useful, especially if spec varies<\/li>\n<li>5+ quotes: you&#8217;re wasting installers&#8217; time and your own; convert one to an order<\/li>\n<\/ul>\n<!-- \/wp:list\n\n\n<p>A good mix: 2 local FENSA-registered independents + 1 national chain (for the comparison) + 1 from your postcode via a comparison service.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What to check before signing the contract<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cooling-off period<\/strong>: by UK law (Consumer Contracts Regulations 2013), for doorstep sales you have 14 days to cancel without reason. Get this in writing on the contract.<\/li>\n<li><strong>Deposit protection<\/strong>: FENSA offers deposit protection insurance \u2014 ask if the installer participates.<\/li>\n<li><strong>Penalty clauses for late completion<\/strong>: installation should start within agreed dates. A fair contract includes compensation if they're more than 2 weeks late without cause.<\/li>\n<li><strong>Making-good clause<\/strong>: who's responsible for plaster\/render damage during install, and is repair included?<\/li>\n<li><strong>Payment milestones<\/strong>: avoid paying in full upfront.

Enter the company name \u2014 if they're legitimate, you'll see active registration, their membership number, and the postcodes they cover. If a self-claimed \"FENSA installer\" doesn't appear in the database, walk away.<\/p><\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>What should I do if the installer goes bust mid-job?<\/strong><\/summary><p>If you used a FENSA or Certass registered installer, your insurance-backed guarantee covers completion \u2014 contact the scheme directly. If you paid by credit card, you also have Section 75 protection for amounts over \u00a3100. If neither applies, you may have a claim via the Consumer Rights Act 2015 or through the installer's liquidator.<\/p><\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>Can I get my deposit back if I change my mind?<\/strong><\/summary><p>Yes, within 14 days of signing for doorstep sales (Consumer Contracts Regulations 2013). The installer must refund your deposit in full within 14 days of cancellation. For online or showroom sales, the 14-day cooling-off period applies unless work has commenced with your agreement.<\/p><\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>How do I spot a fake review?<\/strong><\/summary><p>Fake reviews usually share these signs: overly generic language (\"great service, highly recommend\"), clustered dates (e.g., 15 five-star reviews in one week), no specific product or service mentioned, no location details, reviewer profiles with few other reviews. Real reviews include minor criticisms, specific product names, and installation dates.<\/p><\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>Is paying cash ever OK?<\/strong><\/summary><p>For small jobs under \u00a3500 \u2014 possibly. For full-house double glazing costing \u00a35,000+ \u2014 never. Cash has no chargeback rights, no tax trail, and gives you zero recourse if something goes wrong. Credit card (for \u00a3100+ protection via Section 75), bank transfer, or finance are all safer.<\/p><\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>Should I use a fitter recommended by a friend?<\/strong><\/summary><p>A friend's recommendation is a great starting point \u2014 but still get 2 other quotes for comparison. Your friend's job may have been 5 years ago when prices were different, or the installer may have changed quality\/pricing since. Always verify current FENSA status too.<\/p><\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>What's the best way to find a local double glazing fitter?<\/strong><\/summary><p>Three sources work well: (1) comparison services like Findfitter that vet installers and match 4 FENSA-registered fitters to your postcode; (2) your local FENSA database search; (3) personal recommendations from neighbours who've had recent work done. Avoid: Google Ads (inflated prices) and doorstep callers (always high-pressure).<\/p><\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>Can I see the actual product before I order?<\/strong><\/summary><p>You should. Ask to visit the installer's showroom or trade counter. Inspect: frame finish, colour consistency, weight of glass, smoothness of opening mechanism, locking feel, and trim quality.
