Window Style Matcher
The right window style for your home depends on its era. Pick your house's age below to see what was originally fitted, what modern replacements suit the architecture, and what conservation or heritage rules affect your choices.
These recommendations are based on period architecture conventions, building regulations (Part L 2022), and typical conservation-area policies across England, Scotland, Wales, and Northern Ireland. Always check with your local planning authority before proceeding with replacements in a conservation area or on a listed building. See our conservation area guide for full detail.
Why era matters
UK housing stock spans six centuries, and window design evolved dramatically alongside construction techniques, fashion, and regulation. A sash window that looks perfect on a Victorian terrace would look out of place — and may be refused by a conservation officer — on a 1930s semi. The Style Matcher helps you avoid that mistake before you get to the planning-application stage.
Each recommendation considers three factors:
- Aesthetic appropriateness — profiles, sightlines, proportions, and finish that match the original architecture.
- Regulatory feasibility — Part L U-value requirements, conservation area restrictions, and Article 4 Direction coverage.
- Practical budget — three tiers: best (aesthetic fidelity), compromise (good balance), and budget (most affordable compliant option).

What about listed buildings?
If your home is Grade I, Grade II*, or Grade II listed, you need Listed Building Consent before making any window changes — even matching replacements. Our vacuum glazing for listed buildings guide covers your options, including slim-profile double glazing and secondary glazing that some conservation officers accept.
