New build homes are already 65% more carbon-efficient than older homes, but you can maximise savings by programming your thermostat, using LED lighting, running full appliance loads, taking 5-minute showers, closing curtains at night, being mindful of phantom power draw, and incorporating small daily habit changes into your lifestyle. 

Moving into a brand new home is genuinely exciting…

…There’s that fresh smell of paint, pristine carpets, new fittings, and everything works, well, like new! But here’s something even better – new build homes come with a golden opportunity that older homes simply don’t have: built-in energy efficiency. 

New build homes, particularly those from Wain Homes, are constructed with the most current building standards to give you the best start to saving energy. Nevertheless, there’s always room for improvement, with energy-saving hacks that anyone can implement. Let’s explore some smart, simple, and practical strategies to save energy at home, reduce your carbon footprint, and keep those energy bills in check.

The energy-saving advantages of a new build

But first, and most important, let’s celebrate. Built with energy efficiency in mind, your new build home means better insulation, modern boilers, updated electrics, and air-tight constructions. Aside from keeping your home warm and cosy, all these aspects come together to ensure your home consumes energy only when needed and prevents it from being wasted when not. So much so that new build homes emit 65% less carbon a year compared to their older counterparts. That equates to an incredible annual saving of up to £979.

The thing is, knowing you have an efficient home that keeps you snug and saves the pennies is one thing – actually getting the most out of it? That’s a different story. Think of your new build as a high-performance machine – it’s already brilliant, giving you the very best of contemporary living, but with a bit of know-how, you can unlock even more potential and save even more energy…

That’s where our energy-saving tips come in…

1. Understand your heating system

Typically, the most costly utility in any home is heating. Fortunately, most new builds will come with a modern condensing boiler or an air source heat pump, both of which are excellent, eco-friendly options that can help reduce costs. However, many homeowners struggle to fully grasp how these systems actually work. We’re not talking about delving into the technical intricacies and becoming a boiler whizz; instead, it’s essential to spend some time learning how to manage and make the most of their usage effectively. So, dust off that manual and give it a read. Familiarise yourself with the different settings and discover when to use them.

Fortunately, most current systems are equipped with user-friendly programmable thermostats that make it so easy to change your home’s temperature and allow you to set different temperatures for various times of the day. You can save energy at home incredibly effectively by simply programming your heating to kick in just before you wake up and drop back down before you leave for work.

2. Switch on energy-saving lighting

Here’s a ‘how to save energy at home’ tip that’s as easy as turning on a light bulb, literally! If you recently moved into a new build, chances are it came equipped with LED lighting. Make sure every room in your house has these energy-efficient bulbs. LED bulbs consume approximately 75% less energy than traditional incandescent bulbs, and they last significantly longer, eliminating the need for frequent replacements.

To enhance this plan, consider incorporating smart lighting. Previously regarded as complicated and expensive, they are now readily accessible and straightforward to install. With this option, you can easily control the amount of light you need and when it’s needed, all from your smartphone. You can schedule settings for when you’re away from home and dim the lights while you’re relaxing on the sofa at night.

Oh, and lastly, don’t forget to switch the lights off when you leave the room. We know it sounds obvious, but it’s a routine worth getting into.

3. Optimise kitchen appliances

Your new kitchen features the very best of modern appliances, which is excellent news. Strictly speaking, today’s kitchen appliances consume less than older models due to technological advancements and more stringent energy efficiency standards. But how you use them makes a massive difference to your energy consumption. For this section, we’ll examine some key culprits.

  • Dishwasher: Most modern dishwashers actually use less water than hand washing, so you’re already ahead of the game. However, to maximise the amount of electricity it requires to run, make sure you try your best to fill it to capacity before running a cycle.  Also, skip the pre-rinse and any air-dry settings; modern dishwashers are designed to handle lightly soiled dishes without pre-rinsing. Simply opening the door immediately after a cycle is more than enough to let the dishes air-dry.
  • Cooker: When cooking, try to match your pan size to the diameter of your hob ring. Using a small pan on a large ring is a waste of energy. Also, use lids on pans – it’ll heat your food faster and use less energy. Simple physics, really.
  • Fridge & Freezer: Your fridge and freezer will run constantly, so ensure they operate efficiently. Don’t block the vents at the back; keep them away from heat sources, like radiators or direct sunlight.

4. Adopt the ‘power down’ protocol

Most electronic devices, whether it’s a TV or a charger, use energy even when in standby mode, dubbed ‘phantom load’. Unless it’s an important device that needs to be on attention all day, like a clock or a router, many of these non-essentials, such as: 

  • TVs
  • Laptops
  • Kettles
  • Toasters
  • Phone chargers

…do not benefit from being on standby – so turn them off. 

A practical shortcut to doing so is to plug these devices into a power strip, allowing them to be powered down simultaneously. While it may not actually save tonnes of energy, it all contributes to your overall home energy saving goals.

5. Shorten shower times

Hot water is one of the biggest energy consumers in any home, so the bathroom is where you can make real savings; and this one’s an easy one. Here’s the thing about new builds – you’ve likely got decent water pressure, which means shorter showers actually feel fine. Aim for five-minute showers instead of lengthy, indulging soaks. Also, whenever possible, opt for a shower over a bath, as a bath roughly uses about twice as much hot water as a brief shower.

6. Close your curtains and blinds

New builds typically come with double or triple-glazed windows and well-fitted doors – and that’s brilliant. But here’s the catch: all that fancy glazing only works if you actually close your curtains and blinds, especially at night. Seriously, it’s one of the easiest ways to save on home energy that often goes unnoticed.

Close your curtains or blinds as soon as the sun goes down. This creates an extra insulating layer, preventing heat from escaping through your windows. In summer, reverse the process – close them during the day to keep the heat out and reduce the load on your air conditioning (if you have it). While you’re at it, keep any room-dividing doors closed too. There’s no point in heating every room in your house if you’re only using the living room; concentrate your heating where you actually are.

7. Be laundry wise

Your new build is likely to feature a modern washing machine, probably an energy-efficient model. Since many detergents work effectively in cold water, make the most of it by washing clothes in cold water whenever possible, saving significant energy by not heating the water. Additionally, like the aforementioned dishwasher, only run your washing machine when you have a full load. The same applies to the tumble dryer; or instead, try line-drying clothes when the weather permits. It’s free, and your clothes will last longer anyway.

8. Consider your habits

Lastly, the most significant savings often come from simply being more mindful about your energy use. New builds are efficient, but they still respond to how you live in them. Little lifestyle changes – such as not leaving appliances running, closing doors, turning off lights, and using hot water thoughtfully – genuinely add up over time.
