How do I choose aluminium windows?

To better understand the key features and advantages you can get by going with any one of the top 5 manufacturers, we’ve outlined some of their key specifications for you to compare. These include:

Finance options

Rather than paying a large lump sum, manufacturers will often offer the chance to spread the costs of new windows installations by making fixed monthly payments over an agreed period. 

These agreements can take the form of interest-free credit, flexible payments, or buy-now-pay-later contracts. If you already have aluminium windows but want to improve their glazing, you can also apply for a government program. While not explicitly window grants, schemes like ECO4 can be very beneficial for improving glazing on existing windows. Be sure to check if any apply to your region.

Efficiency range 

Windows Energy Ratings (WER) are rated up to A+++. The most efficient windows ensure little to no heat loss for optimal heating comfort. This also saves you in monthly energy bills. 

Replacement windows in the UK must follow certain regulations issued by the Energy Performance of Buildings Directive. 

Across the UK, new windows require either a U-value of 1.6 W/m²K or a minimum Band C Window Energy Rating (WER), even for single window installations.

Warranty period 

A lengthy warranty period gives you peace of mind that any manufacturer defects will be covered. Most warranties will also cover mechanical window parts, material defects, and installation errors.  

Generally, more expensive windows will come with the longest warranty periods. 

Note about aluminium window prices

Manufacturers base their aluminium window prices on the size and amount of windows your home requires, meaning prices vary according to your home’s specifications. Per aluminium window, you can expect to pay between £210 – £1,615, depending on the size and type you need. Overall, while not the most affordable material, there are options for cheap aluminium windows.
