The cost of Double Glazing a 3 bed house is a regular question we get and the answer as alwayys varies depending on the size of the property, the number of bedrooms, and the size of the windows. Even the type of window will have an impact on the price

Double glazing is a popular way to improve the energy efficiency of your home by preventing heat loss during the colder months, make your home more secure, and reduce external noise from being heard inside.

How Much Is Double Glazing For A 3 Bedroom House?

The average cost of double glazing a 3 bedroom house in the UK is between £5,000 and £7,000. This is a significant amount, but it will have a huge impact on your property.

National double glazing companies generally work at the £300 per frame mark, but this can vary depending on your location and the type of windows you want in your home. Local installers could offer different prices, but your quote will include material costs and the labour involved.

A bay window, for example, typically has 5 frames, meaning the installation would cost £1,500. With this in mind, the cost to double glaze a 3 bedroom house can easily exceed £5,000 – which is why the type of windows makes a difference to the price.

What Influences The Cost To Double Glazing A 3 Bedroom House?

Some of the factors that influence the cost to double glaze a 3 bedroom house are the window sizes and styles, the materials used, add-ons, and finishes. You should also keep in mind that installers will have different prices and the energy ratings you want to achieve.

As you might expect, bigger windows are more expensive. A small bathroom window might cost you £150 whereas a regular 180cm x 120cm on the other hand might cost upwards of £350, depending on the style chosen.

Certain styles are easier to assemble and install, while others require more work. This can add to the price. That means you need to know about the different types of windows available, their prices, and whether it fits with the style of your home.

Can Anything Else Affect The Average Cost Of Double Glazing A 3 Bedroom House?

While the style of window can have the biggest impact on the average cost of double glazing a 3 bedroom house, there are other factors to consider, too.

For example, if you are replacing your windows instead of installing them in a new house, you have to consider the cost involved in dismantling the existing frames and disposing of them.

You may also have to pay for a survey and assessment, and there may be additional operating expenses. These could include scaffolding for windows that are not on the ground floor.

There are other factors to think about when it comes to the cost to double glaze a 3 bedroom house, though.

Your Choice Of Windows Frames

There are 3 main choices of materials for your window frames:

  • uPVC
  • Wood
  • Aluminium

Each one will impact the cost to double glaze a 3 bedroom house, with uPVC often being the cheapest option – as well as being the easiest to maintain.

uPVC is one of the most common types of window frames found on UK homes. They are lightweight, durable, energy-efficient, and cost-effective, which makes them an obvious choice. They don’t have the natural look of wood, but this is less of a concern for most people.

Aluminium frames look modern and are durable. They are lightweight, so handling costs are lower. They also have the largest number of colour options available, although they have a higher cost.

Wood window frames are the most natural in appearance, but also the most expensive. They are energy efficient, however you will need to put a lot more time and effort into maintaining them to keep them performing at their best.

Finishes For Your Windows

The average cost of double glazing a 3 bedroom house also changes depending on the finishes and effects you want for your windows.

Instead of standard white handles, you can choose chrome or gold fittings. These add style and character but come with a bigger price tag. For some materials, you can also choose the colour you want. This is perfect if you want to make sure your house matches your style or fits in with a certain theme. Extra security measures are also available, if desired.

Toughened glass will be needed if your window is 80cm from the floor. This glass is treated in a way so that if it breaks, it will shatter into harmless crystals rather than dangerous shards.

You can also consider coloured glass panels, bars, and other design flourishes which can add to the overall price of your windows.

Installer Costs

The average cost of double glazing a semi detached house can be drastically affected by the installation costs. For example, a one-person local company might replace a single window unit for much less than a large, national supplier.

A local contractor will self-regulate their quality to make sure they maintain their reputation. They’ll also have lower overheads which will translate into a cheaper cost. They might not have a minimum job size, either.

Since they operate locally, you could ask to see other jobs that the installers have done, and get reviews and feedback from previous clients.

On the other hand, they might not be as technically trained as installers from larger companies. While these companies have higher overheads – leading to higher costs – they have greater expertise, standardised services, and certifications too.

However, most salespeople in these companies start with a higher figure. You may need to negotiate to get the best price.

Thermally Efficiency

Thermally efficient windows offer much better insulation for your home, reducing your energy usage because less heat escapes and you don’t have to turn the heating on as much. These savings can help offset the cost of double glazing over time.

Double glazed windows have two layers of glass with a pocket of air between them. This sealed pocket of air insulates the heater air inside the house from the colder air outside. As a result, the heating system in your house does not need to work as hard.

Even an energy efficiency rating of C can lower your energy bills by up to £75 a year. However, you could reduce the cost of double glazing your 3 bed house further by getting windows with A or A+ energy ratings!
