Merton

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.

FAQs

Should I use a Fensa registered installer?

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.
