Rules in England
In England, replacement windows must meet 1.4 W/m²K, or a Window Energy Rating of band B or better. Replacement windows are a controlled fitting. A competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council within 30 days; otherwise a building control body approves it.
Planning: Replacing windows on a house is normally permitted development if the new ones look similar. New upper-floor windows in a side wall must be obscure glazed and fixed, or open only above 1.7 m. Flats and maisonettes have no householder permitted development rights, so a change that alters their appearance needs planning permission. An Article 4 direction in a conservation area may mean permission is needed, and listed buildings need listed building consent.
How it works
We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.
- Free survey and a written quote fixed for the specification
- Glass build-up and whole-window U-value on every quote
- Written handover pack at the end of the job
- Guarantees on frames, units and fitting in writing
Questions
How long do alu-clad windows take to make?
Typically 8 to 12 weeks from survey, sometimes longer for big projects.
Can I choose different colours inside and out?
Yes. The aluminium can be any RAL colour and the timber inside can be natural, stained or painted.
Do alu-clad windows suit Passivhaus builds?
Many alu-clad systems are designed for low-energy homes. If you need Passive House Institute certified components, ask and we will price systems that hold that certification.
Do you cover all of Essex?
We arrange surveys and fitting across Essex.
Do I need permission for alu-clad timber triple glazed windows in England?
In England, like-for-like replacements on a house are normally permitted development; flats need permission if the change alters their appearance, Article 4 areas may need permission, and listed buildings need listed building consent.
