Replacement windowsare a good idea if you have windows that allow a draft, have any condensation, show frame deterioration or are difficult to open and close.
Unless you live in Mottram Conservation Area, you do not need planning consent to install replacement windows. However, if you live in a listed building, you would require listed building consent.
In England / Wales all replacement window installations are subject to building regulation approval or in most cases are covered by the FENSA self certification scheme.
In particular they are subject to the PART A1 - Structure part of building regulations.
The style of a replacement window should be compatible with the house. Most companies carry a variety of colors for interior and exterior framing and trim. Some other decorative options are beveled glass, muntin squares (trim embedded between panes) bay or bow windows and mini-greenhouse style windows.
Vinyl and wood are durable and perform comparably. Aluminium exterior trim is commonly used.
When selling property, surveyors will ask for evidence that replacement windows installed after April 2002 complies with the new Building Regulations. There are two ways to prove compliance:-
a certificate showing that the work has been done by an installer who is registered under a FENSA Scheme
or
a certificate from the local authority saying that the installation has approval under the Building Regulations.
