Yes. All installers in our network are FENSA registered, which means they are certified to install replacement windows and doors in compliance with UK Building Regulations. FENSA registration also means your installation comes with a 10-year insurance-backed guarantee.
Most window installations take between 1–3 days, depending on the number of windows and complexity. A single window can be replaced in as little as 2–3 hours. Your installer will give you a more precise timeframe during their survey.
Completely free for homeowners. We're funded by the installers in our network, who pay us a small referral fee when they receive a lead. You receive unbiased quotes with no obligation to proceed. There's no catch.
In most cases, replacing windows like-for-like does not require planning permission in England and Wales, as it's considered "permitted development". However, if you live in a conservation area, listed building, or are changing the style of your windows significantly, you may need permission. FENSA-registered installers handle Building Regulations compliance automatically.
