Double glazing is hugely popular choice for windows and replacements today for a wide range of reasons. The intelligent designs can offer increased security and sound proofing to increase the comfort of the inhabitants of a home. Furthermore, the double pane style manages to maintain more heat energy than traditional windows which can be significantly beneficial to conserving energy and reducing heating needs. One consideration to be made before choosing to install double glazing, however, is whether or not planning permission is required as there is a fairly comprehensive and broad set of regulations and laws regarding window replacements. Some local planning authorities may differ slightly on their own specific regulations and these kinds of rules are prone to be altered and amended in small details so it is always recommended that a local planning authority is contacted before installing double glazing. Many companies provide these services and check the specifics themselves, but it is worth ensuring that this side of matters is covered as it is ultimately the homeowners responsibility.
No Planning Permission Needed
When it comes to installing double glazing, more often than not planning permission is not required as the alteration made to the house is minimal and it is highly unlikely that the replacement of windows will overstep any rules or affect the neighbours in any way. Furthermore, double glazing will be unaffected by regulations that require replacement windows to follow minimum levels of insulation as double glazing is highly energy and heat insulating already. Generally, therefore, double glazing installation does not require planning permission.
When Planning Permission is Required
There are numerous notable exceptions to the rule, however, and checking these criteria is very important. Double glazing does not usually need planning permission when installed in buildings which are used as homes or ‘dwelling houses’, such as semi-detached or detached houses. On the other hand, hotels, commercial and community buildings and some other kinds of properties will tend to require planning permission. Flats do not fall under the dwelling house category and will require planning permission too.
Another major factor which may require a homeowner to attain permission before installing double glazing is if the house lies within a conservation area. There are several conservation areas around and homes in these places are protected to some extent so planning permission needs to be granted. These areas aim to maintain a certain style and thus any alteration which may change the look of a house so that it is no longer in keeping with the rest of the conservation area may not be given permission. Usually a proposal will be checked in a number of ways before permission is rejected or granted. The most important factor considered is of whether the character of the area will be maintained, but if the windows will not be visible to the public or if the windows will in fact be a visual improvement on the previous windows, the proposal may be accepted. There may also be public notices for local members and residents to comment on the proposed installation and different councils may emphasise different factors.
