Will I save money on my heating bills by installing double glazing?

About 20% of a home’s heat escapes through windows. The savings you can make by fitting new windows will depend on the type of glass and frames on your house. But replacing all single glazed windows with A-Rated double glazing could save the average householder several hundred pounds per year on heating bills.

To help you work out how much you could save, trade association GGF (Glass & Glazing Federation) has a useful online calculator.

Can you supply windows for use in UK conservation areas?

We can supply windows that are suitable for conservation areas. We at Glassier have a number of suitable options for you. It is essential that you check with your Local Authority regarding the status of your property in terms of conservation. Sadly we are unable to enquire on your behalf but we are only too happy to help you.

How should I protect my investment?

Although PVCu products require very little in the way of maintenance, there is a handy little guide which tells you everything you need to know about looking after your new installation.

Do I need to get planning permission before installing windows and doors?

You do not normally need planning permission to replace existing windows or doors, although you will if you have a listed property and you will need to check to see if you are located in a conservation area, as you may be restricted with what designs or materials you are allowed to replace the existing windows with.

If you are building an extension the windows would form part of the building’s planning application, assuming that the extension itself requires planning approval. You would not normally require planning approval separately for the window element of the work. 

Please confirm these details with your local council as these laws are subject to change and we cannot accept any liability for any errors made in this regard.

More information can be found from your Local Authority Planning Portal.

 What types of double glazing frames are there? 

The most common type of window frame for double-glazed windows is PVCu - or, to give it its full name, un-plasticised polyvinyl chloride. Not only is it around a third of the cost of traditional wooden frames, but it's also recyclable, durable and the most energy-efficient frame type. PVCu window and door frames are available in a variety of colours and finishes, and are virtually maintenance free. Other materials include timber or aluminium frames.
