The London Borough of Waltham Forest is a London borough in north east London, England. The local authority is Waltham Forest London Borough Council. It covers an overall area of around 14.99 square miles. The borough is situated between Epping Forest and Essex in the north, Redbridge in the east, Newham and Hackney towards the south, and Haringey and Enfield towards the west, where the River Lea and Lea Valley and the surrounding parkland forms a green corridor separating north and east London. Key districts are Leyton and Leytonstone in the south, Walthamstow in the centre, and Chingford in the north.
Based on population estimates from the middle of 2014, Waltham Forest is a borough with a permanent population of about 268020 individuals. The north and south of the borough, split by the North Circular Road, contrast markedly in terms of ethnicity and socio-economic indicators, with built-up urban districts in the south having inner-city characteristics, and more affluent residential development to the north with open spaces, parks, and playing fields.
Historically referred to as the seat of the Arts and Crafts Movement under the stewardship of William Morris, Waltham Forest has continued to help numerous contemporary artists and art groups. The annual E17 Art Trail, which consists of open studios, exhibitions and events, is the most significant art event within the borough, and there's now a related occasion in Leytonstone. Waltham Forest was among the list of six London boroughs that hosted the 2012 Summer Olympics.

Double glazed windows are one of the most popular window options for home and property owners in the United Kingdom and reasonably so. They are able to offer a wide range of benefits to home owners which includes being energy efficient, reducing the build up of condensation on windows and black mould growth, significantly reducing background noise for a better relaxation or night rest, increasing the value of your property as well as adding to the aesthetic appeal of your home. So if you’ve decided to lay your hands on a double glazed window, you’d probably also like to know how much it’s going to cost. Well, providing a simple and accurate answer to the question of double glazing window cost is almost impossible as there are so many factors that influences the price including the materials and style.
Several suppliers usually provide the list of their double glazing windows on their websites, however these prices are only for basic off the shelf window and most often without the installation cost. Furthermore, if you require some special features to your double glazed window, then this will also tell on the total cost of the window.
So how much will a double glazing window cost? The cost of a double glazing window usually ranges between £100 to £3,200 per window, depending on the available options.
To have a more accurate estimate of the cost of a double glazing window, you’ll need a obtain a survey from a double glazing installer who can take into account any possible complications that may arise when installing your windows while also giving an advise on the most suitable window style for your property.
As well as keeping your home warmer and reducing noise, you’ll notice a saving on your energy bills from installing double glazing. If you install A++ rated windows in your home after having single glazing, you could save up to £120 year on your energy bills. The Energy Saving Trust has more information.
The energy efficiency of windows is measured using ratings, varying from A, the most efficient, to G, the least efficient. This scheme is run by the British Fenestration Council (BFRC). To comply with Building Regulations you’ll need windows of energy efficiency at least level C.
Using a Fensa registered installer isn’t compulsory but it helps to protect you from cowboys and rogue traders. It will also make life a whole lot easier in regards to Building Regulations. Replacement windows must meet a certain energy efficiency rating and once fitted you need a certificate to show your installation complies. By using a Fensa registered company they’ll issue this certificate, otherwise you’ll need the council to look at the new windows.
