Are upgraded doors right for my house?
New doors are a great option if you have old, draughty or poorly insulated doors, or single-glazed windows. Upgrading your door is a cost-efficient way to reduce heat loss in your home.
If you already have double or triple-glazed windows, there may be less benefits from upgrading your doors.
How do you get UK government grants for double glazed windows or doors?
There is limited grant support for replacing windows at the moment, however this can change. It is restricted by grant eligibility criteria and based on income and the availability of registered suppliers’. Click here to find out which grants are available now.

The type of door you choose.

How do upgraded doors increase energy efficiency?
Draughty doors can let about 15% of your home’s heat escape. When you replace them with better doors, heat stays inside and keeps your home warmer. The result? A more energy-efficient home and lower heating bills.

How energy-efficient doors work
Energy-efficient doors offer an extra layer of protection against the cold. These doors are designed to keep heat from escaping, so your home stays warmer in winter. Some doors also come with double or triple-glazed windows for an extra layer of protection.
This means you won’t need to use as much energy to keep your home comfortable, which helps lower your energy bills. New doors also help reduce noise from outside, making your home quieter and more peaceful.

What do upgraded doors look like and where do they fit in your house?
Energy-efficient doors look just like regular doors and go in the same place as your old door. The difference is they’re thicker and made with special materials that keep the heat inside your home.
They also have draught-proof seals around the edges to keep out cold air, so your home stays cosy.
