The London Borough of Lewisham is a London borough in south-east London, England and forms a part of Inner London. The borough wasestablished in 1965, by the London Government Act 1963, as an amalgamation of the former location of the Metropolitan Borough of Lewisham as well as the Metropolitan Borough of Deptford, which had been established in 1900 as divisions of the County of London. However, minor boundary modifications have occurred since its creation. One of the most significant amendments were made in 1996, when the previous part of the Royal Docks in Deptford was transferred from the London Borough of Greenwich.
The local authority is Lewisham London Borough Council and it's based in Catford. The borough covers an overall area of about 13.57 square miles. It is surrounded by the Royal Borough of Greenwich to the east, the London Borough of Bromley towards the south and also the London Borough of Southwark towards the west. The River Thames forms a short section of northern boundary with the Isle of Dogs within the London Borough of Tower Hamlets. Deptford Creek, Pool River, River Quaggy and River Ravensbourne pass by means of the borough.
As outlined by population estimates made during 2014, Lewisham is a borough with approximately 291933 permanent residents. Around 43 per cent of households are owner-occupiers. The Prime Meridian passes through Lewisham. Blackheath, Goldsmiths, University of London and Millwall F.C. are positioned within the borough.

If you’ve got a problem with condensation and don’t have double glazing, you should find that getting new windows will help. Condensation is caused by warm air meeting a cold surface which then turns into water droplets. With two panes of glass, less heat will escape from your home and keep the window warmer, meaning when steam from the bathroom or kitchen touches your windows there should be less condensation.
If a window is double glazed, it has two panes of glass that have a space between them containing argon gas. The gas works as an insulator, keeping heat inside the house as well as reducing noise. It also strengthens the window.
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 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.
We can help you get more secondary glazing work with our qualified job leads and boost your business.
