The London Borough of Merton is a borough in south-west London, England. The borough was formed under the London Government Act 1963 in 1965 by the merger of the Municipal Borough of Mitcham, the Municipal Borough of Wimbledon plus the Merton and Morden Urban District, all formerly within Surrey. The borough derives its name from the historic parish of Merton, which was centred on the location now referred to as South Wimbledon. The local authority is Merton London Borough Council.
Based on population estimates made during 2014, the borough has a permanent population of about 203515 inhabitants. The borough is also served by a number of London Tramlink stops from Wimbledon, which goes to Croydon, New Addington, Elmers End and Beckenham. It is the only London Borough which has tube, rail and tram services.
The primary industrial centres in Merton are Mitcham, Morden and Wimbledon, of which Wimbledon is the biggest. Other smaller sized centres consist of Raynes Park, Colliers Wood, South Wimbledon, Wimbledon Park and Pollards Hill. Each year, Wimbledon, one of the four tennis Grand Slam tournaments, is held at the All England Lawn Tennis and Croquet Club in Church Road Wimbledon. The event happens over a fortnight at the end of June and start of July and it's the largest annual sporting event to take place in the UK, attracting more than 200000 guests in the course of the Wimbledon fortnight.

Double glazing frames don’t just have to come in uPVC and are available in other materials including aluminium and wood too. Wooden or timber windows are more suited to properties with a traditional look and are often the frame of choice for listed buildings and homes in conservation areas. When properly maintained wooden windows can last well for years but can be up to three times more expensive than uPVC.Aluminium is the strongest and most durable option. As a metal it is highly resistant to the UK’s changing weather conditions and won’t rust, warp, crack or peel. Aluminium offers a modern appeal and is available in a range of colours.
On the grand scale of things there isn’t a huge difference between B-rated windows and A-rated windows. Consumer watchdog Which? have calculated an extra 6.5% would be saved on energy bills with A rather than B rated panes. Be aware that A rated windows are slightly more expensive, however.
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.
Most installers will not need you to be at home while they are fitting your windows. It is a good idea to be present though, just in case they have any questions for you and perhaps for your own peace of mind. If you cannot be there, you will need to arrange access to the property and/or agree securing the property at the end of the day.
