The money you can avoid paying with a well-installed set of windows is not insignificant, and with the best energy-efficient windows, you can stand to save up to £150, according to the Energy Saving Trust. In Hertfordshire, single-pane window leaks are a significant burden on homeowners, leading to higher energy bills and reduced budgets. So, what can you do to maximise your window energy savings instead?
Below, we offer information on selecting energy-efficient windows and maximising the savings you can guarantee for your home. So, read on and get ready to take steps to a more frugal tomorrow.
Finding the Best Energy-Efficient Windows for Your Home
When a home heating or cooling system is past around 10-15 years, according to Bio Friendly Planet, you should consider replacing it with a more energy-efficient model.
You can quickly check the window’s energy efficiency based on its BFRC rating. This system assesses how good your windows and doors are and gives them a rating of between A++ and E. You can usually find these inside the frame unless you have removed them.
Check that they have a:
- Hologram
- Link to the BFRC database
- Valid reference on the BFRC website
You will want to look for A++ and A+-rated windows, which are most likely to have robust insulation. You can also ask the installer or salesperson to talk you through the rating of the window, ensuring that you are likely to receive a lower thermal transfer rate than your currently installed windows.
To get the closest to an A++, you will want a longer “solar gain” arrow and a lower “air leakage” number, as close to zero as possible.
Upgrading Your Windows
Once you have chosen the window, make sure that its frame matches your home’s heating requirements, including any local ordinances. Also, be aware that the rating of any new frame doesn’t only relate to the glass. For example, if you install better glass on a metal frame, you may still have a significant heat transfer.
So, work with a good installer who can be up-front about how things like the materials used can impact heat, and ensure that you receive a written price quote so that you can return to the deal later, if necessary. Such a written price is then valid for up to 60 days. Discuss with them the material options you have, including the use of Georgian or Astragal bars and if these might affect your heat transfer, to help you make a better decision.
Pick A Frame Style That Suits Garden City Homes
If you live within one of the Welwyn Hatfield conservation areas, you will need to be aware of the limitations when making changes to your property, including the windows. If you are within one of these regions, you must maintain the architecture and “historic qualities” of your windows.
While you can apply for permission to change the look of your building, such as adding dormer windows, this is not guaranteed. It is also important to note that not all energy efficiency or heat retention measures will work in such homes. Traditional building construction and the materials used in such old buildings may not always be compatible with up-to-date heating methods, so you should discuss your window insulation options with experts before planning.
Consider updating your windows with technology that allows you to improve them without changing their shape or size. For example, you can now include insulating glass in your fixtures to keep heat in without losing their style. Such recent advances can mean you will be much more comfortable indoors without losing something special about your home’s curb appeal.
Even if your home is not in one of these conservation areas, you may still want to match the historic nature of the local area. If that’s the case, consider investing in:
- Sliding sash windows
- Georgian bars
- Astragal bars
- Diamond-leaded patterns
- Square-leaded patterns
You could also use flush-sash uPVC windows to match the shape of many older wood-built cottages. These still offer modern insulation, and you can choose colours or wood-grain style finishes to give you the desired mood.
Choose Energy-Efficient Window Types
While the specific window might require you to look for a highly-rated option, as mentioned above, the larger decision you will want to consider is whether you use:
- Double-glazing
- Triple-glazing
- Safety glass inserts
- LINIAR uPVC profile
- Internal beading
Better Homes, Better Health confirms that installing double-glazed windows into your home can save you money on your yearly expenses. Apex Windows also confirms this, boasting high-quality double glazing that often scores an A+ on tests.
Similarly, their triple-glazing also offers A++ energy efficiency, perfect for warm summers and cool winters. If you live on a loud road, this can also ensure that the minimum noise leaks through, helping you get a good night’s sleep and enjoy your day in peace.
Safety Glass Inserts
Laminated safety glass adds an extra layer to your windows. While the primary intent of this is to prevent it from shattering when struck, it also creates an additional insulating layer, especially when used alongside double- or triple-glazing. The extra layer makes it harder for heat to transfer between different materials and increases the pane’s mass slightly, slowing heat conduction between the inside and outside.
The safety glass can also block more UV rays than standard glass, reducing the heat that transfers into the building in the warmer months while trapping it during colder periods and helping you keep a stable temperature indoors.
Laminated safety glass also helps protect the seals in windows from moisture and slight movements. Over time, this prevents minor condensation buildups and can ensure that the window loses less effectiveness over its longer lifespan.
LINIAR uPVC Profile
LINIAR uPVC is a type of window specifically designed to prevent significant transfer of heat through the frame of a window, usually an area with substantial thermal loss. Instead, it has multiple chambers built within its structure. Heat often has difficulty passing between materials, and the chambers do not allow for significant air movement, so the same heat does not move between individual chambers quickly.
Developers also built these frames without the need for steel reinforcement. As metals have very high heat conductivity, removing them has led to these high-quality frames having a heat retention value that matches many triple-glazed systems, as well as:
- A+ energy ratings on average
- Eco-friendly and lead-free construction
- High levels of security meeting PAS 24:2022 standards
- Superior waterproofing
- No need for extra inserts
Internal Beading
A tightly-fitted internal bead can protect and compress the seals on your window, reducing air leaks to almost nothing and preventing heat loss through the glazed areas. Having this protection means that the window will remain in peak condition much longer, while the beading behind the pane shields it from UV and weather, preserving it further.
It also means that you can inspect and replace any seals requiring maintenance more easily, in the warmth and comfort of your home.
Choosing Based on Local Hertfordshire Weather
Ensure that you take into account the nature of local Hertfordshire and the fact that it has much milder winters than many counties further to the north. As such, make decisions understanding that you will likely get more winter sun and potentially colder nights.
The lower rainfall north of London means that, while waterproofing is always essential, you may need to consider the higher levels of sunshine than those further south. We recommend a mid-range glass style, and either double- or triple-glazing to keep the warm sun at bay when you need an escape.
It is, however, important to note where exactly you are in the Welwyn Hatfield and the surrounding region. Hertfordshire is a very hilly area, so if you are higher up and enjoy windier winters, consider edging further toward the triple-glazing side of the fence.
Plan for Rising Energy Prices Across the UK
Nobody wants to pay extra for energy. So, now may be as important a time as ever to note that Ofgem raised the cap for energy cost hikes in the UK as of spring 2025. Expect higher bills as energy companies try to make the most of this.
To avoid the worst of it, consider upgrading sooner rather than later, as even a slight boost in your energy bill will add up quickly. In contrast, the long-term benefits of A++ triple-glazed windows will save you significant money in the long run. Avoid leaking cash as a draught creeps into your home by ensuring your glazing is of the best quality possible.
Apex has more information about this on our website, where we explain how you can maximise window energy savings of up to £480 per year by upgrading. We also offer an online calculator for you to get a more detailed understanding of the ins and outs of what you can get out of working with us.
Saving Money on Double-Glazing
If you are having trouble choosing the best windows due to worrying about their cost, various government schemes in the UK may also help you afford better insulation in your home, including via the windows.
You can book an inspection of your home, allowing a surveyor to look at areas including the windows and doors. They will then inform you of whether you can receive a grant to upgrade your home and reduce the energy consumption of the building.
These interest-free green-home loans mean you can spread out the cost of warmer winters without it impacting your savings. These “green mortgages” give you a much better interest rate, so long as you use the money to upgrade your home to reduce its energy use.
When choosing the windows you want to install, get a quote from the installer that you can then take to the mortgage provider, to give you proof of intent and open the door to the opportunity. You may find that limits on the loan you can get will impact the choice of window you can acquire.
Handling the Details Surrounding the Window Choice
Not only will the specific window you pick out matter, but you will also want to guarantee that you get the best deal that includes all the “bells and whistles” too.
First, confirm the warranty length on the frames, glass, and hardware you pick up. While a ten-year cover is usual, there may be differences depending on your desired window. Talk to the installer about what they offer and if you need to change the window choice based on which you select.
You will also want to investigate your home insurance and whether the windows will remain insured if you upgrade them. So, make choices to ensure it stays valid even if you swap the features out, or discuss the details of your premium with your insurance company before you sign up for an upgrade.
Finally, ensure that the quote you receive lists every detail of the cost. You want to ensure the price includes elements such as the:
- Scaffold
- Waste
- Trims
- Labour
Depending on the window you choose, the installation may have other minor elements you will want to pay attention to when you buy. A high-quality window installer will not hide these from you, but you may need to bear them in mind when choosing your future window frames.
Finally, you will need to select an installer. Check online reviews and testimonials of the options you have around your area, and make sure that you choose a trusted window installer with a good reputation in your local area and several five-star reviews that describe the lengths they go to keep customers like you happy.
