Most window companies will not put a number on a page. We will, because you need one before you invite anyone into your house.

Prices are indicative. Access, the condition of the existing frames and the fitting itself all move the final figure. Your quotation is the accurate number, and it is free.

Spread the cost

Your payment can be spread monthly over a term of up to 10 years.** Finance is provided by Dopple and you apply through our finance portal. A small deposit is due on order, the balance on completion.

Why quotes are valid for 14 days

Glass manufacturing is heavily energy dependent, so our costs move with energy prices. Rather than pad every quotation against a rise that may not happen, we quote the real number on the day. If it lapses, come back whenever you are ready and we will requote free of charge.

VELFAC windows: your questions answered

What is VELFAC?

VELFAC is a Danish-designed window and door system that combines natural internal timber with a durable external aluminium shell. We’re an approved VELFAC distributor and installer.

What's the difference between VELFAC Classic, 200 and Ribo?

Classic offers traditional, balanced proportions with strong acoustic performance. VELFAC 200 has ultra-slim 54mm sightlines and Secured by Design accreditation, suited to contemporary extensions. Ribo has softer Scandinavian styling with more distinctive frame detailing, aimed at design-conscious renovation projects.

Is VELFAC suitable for a period property?

The Ribo and Classic collections are often chosen for renovation projects wanting a more traditional or characterful look, while VELFAC 200 suits contemporary extensions. We can advise which collection fits your property at survey.

Do I need planning permission?

Usually not, but you might if your house is listed or sits in a conservation area, and there are around 200 of those in Surrey. We will flag it at survey if we think you are affected.

Will I get a FENSA certificate?

Yes, automatically, on every installation that qualifies. You will need it when you sell the house.
