House of Windows

The genuinely odd thing about House of Windows is that it sells you double glazing and then walks away before the hard part. The firm manufactures windows and doors to your measurements in Measham, Derbyshire, ships them anywhere in the UK with free delivery, and never sends a fitter. In a trade where the survey, the quote and the fitting team are usually bundled into one inseparable lump, that is a deliberate amputation. Strip out the installers and you strip out the postcode constraints, the appointment diary, and a good chunk of the price. Shipping sealed glazed units across the country also takes some nerve, since glass is heavy, fragile, and unforgiving once it leaves the van.

Supply only, no installation

Everything else about this listing follows from one decision: House of Windows makes the product, and the customer owns the fit. The buying process is built for it. There is a real configurator, not a contact form pretending to be one. A buyer specifies a window or door, chooses the spec, and House of Windows returns a price on screen with no sales call in the way. Anyone who has chased a glazing quote through the traditional appointment-and-survey dance knows exactly how much friction that removes. Around the configurator sit measuring guides, installation documentation, and a custom quotation route for the non-standard jobs the online flow cannot price. The firm plainly assumes its customers can read a measuring guide and act on it, and has built the support to match that assumption instead of hand-holding through every step.

That assumption is also the catch, stated plainly. The buyer measures, so the buyer carries the risk. Order a unit a few millimetres wrong and House of Windows has made precisely what was specified. If the installation goes badly, the firm was never on site to begin with. The 10-year guarantee covers the profile, not the fitting, for the simple reason that the company never fits anything.

Those measuring guides exist because the liability lands squarely on the customer, and anyone weighing the cost saving should pencil in a separate installer before deciding the discount is as generous as the headline price implies. None of this is hidden, but it does reshape who the offer is for: trade buyers with regular glazing work and confident DIYers, not a homeowner hoping to hand the entire job to one company and forget about it.

Windows and doors across multiple styles

The catalogue is wide enough to back the single-source pitch. Windows run to UPVC casement, flush casement, sliding sash, bay, cottage-style and tilt-and-turn, with an aluminium line for slimmer sightlines and triple glazing offered on top of the standard double. Every unit is argon-filled and A-rated, with multipoint locking standard and PAS24 security certification available where break-in resistance is the priority.

Doors cover GRP composite front doors, UPVC back doors, French doors and patio sliders, plus aluminium bifold, French, patio and internal doors, and a Heritage Crittall-style range for the steel-look frames that turn up in half the extensions built this decade. House of Windows also stocks aluminium roof lanterns and flat rooflights, which pushes it past windows-and-doors into something that could genuinely supply a whole extension across several opening types. The technical spec holds across the range, and the breadth is genuine, not a short list padded out with spec options.

From Trustpilot reviews to contact options

The Trustpilot record is the part that does the heavy lifting on credibility. House of Windows has collected 573 reviews at five stars. A handful of curated entries can flatter any rating, but holding five stars across several hundred orders says something about fulfilment and product consistency that a glossy product page never could. The company files as a registered limited company in England with a published VAT number, so it is a traceable trading entity rather than a faceless storefront. On contact, House of Windows is easy to reach: phone, WhatsApp, email, a full business address and stated weekday hours are all present.

WhatsApp up front is a smart call for supply-only work, because the awkward measurement query that surfaces mid-project gets answered in minutes over chat instead of dying in an email thread. When the order is the customer's responsibility, reaching a real person quickly is close to essential.

Who this offer suits best

For the right buyer, House of Windows is a strong, honest proposition. The range stretches from period sash to contemporary aluminium bifolds under one roof, the spec is solid throughout, and 573 five-star Trustpilot reviews indicate the logistics actually work at volume. Set against an installer-led alternative like Internorm or Residence Collection, which sell through approved fitters with installation baked into the quote, House of Windows swaps fitting accountability for lower cost and instant online pricing. That swap is not universally good.

A trade buyer or a competent DIYer measuring their own openings gets a faster, cheaper route here than any survey-and-appointment firm will offer. A homeowner who wants one company answerable for both supply and fit is buying into a risk this model deliberately hands back, and House of Windows is honest enough about it that the mismatch should be obvious before anyone reaches the checkout.
