New name,
new service,
new approach.

At Koncept, we supply and install UPVC, aluminium and composite windows, doors and rooflights for both homeowners and trade customers.

So do many other “double-glazing companies”, including the big TV brands.

BUT here’s the Koncept difference.

We don’t come to your home and talk you into submission for four hours with an outdated, high-pressure sales pitch.

Instead, we let you do the talking.

Call us, send us an email, or upload some drawings of what you want, along with some rough dimensions. We’ll come back to you with a fully itemised quotation that’ll be what you want, at the price you want.

We don’t run a fleet of company cars, employ an army of sales reps, or pay them hefty commissions. So, we save on those costs, and then pass on those savings on to you, the customer.

A new type
of showroom

Our new Wokingham showroom is the place to come and get your hands on our range of high quality windows and doors.

  • Feel how easy it is to open our bi-folding doors.
  • Experience the smooth action of our sliding doors.
  • Admire the good looks of our composite doors.

We’ll just stand back and let our products speak for themselves – no pressure, no hassle, no ‘sign now and save’ gimmicks. And, of course, you can ask us any questions you have.

Supply only?
Oh yes.

If you already have a builder or fitter and just need top quality doors, windows, bi-fold doors, roof lanterns or energy efficient timber windows, no problem. We are more than happy to supply and let you and your team do the rest. That’s why we already have good relationships with house builders, designers, home renovators and more.


Want us to supply and fit as well? Our fully qualified MCT accredited survey and installation teams will fit any of our products to perfection. All products fitted by us as replacements for existing windows and doors are eligible for CERTASS certification.

We are proud members of The Customer Protection Association and, as such, all of our installations are covered by a 10-year, insurance-backed guarantee, giving you complete piece of mind that your home is in safe hands.
