Energy Efficient Homes - Your FAQs

3rd November 2021
Redrow - Inspiration - Energy Efficient Homes - Your FAQs

With energy costs rising rapidly, we might all be reaching for the heating off-switch - unless, of course, we’re in a brand new home. Newer properties are generally far more energy efficient, better insulated and help us to make huge savings and do our bit for the environment; and, while we can take measures to bring older properties up to today’s standards, it’s not without its difficulties or expense…

Why is a new home more energy efficient?

New homes, like those built by Redrow, are designed to deliver improved energy efficiency through design and orientation, water conservation measures, low energy lighting, and more.

Tackling climate change is one of the huge issues facing everyone today along with reducing spiralling energy costs, so both are key considerations.

The right layout and using materials and products which retain heat are crucial, along with greater insulation, high-specification doors and windows, efficient boilers, increased air tightness and energy-efficient lighting. 

Many new homes, like our own, offer solar panels as standard or as an upgrade, which help cut back on bills too and harness natural energy to help the environment, providing the answer to that question: ‘How can I reduce my carbon footprint?’ by reducing emissions.

How much could I save in a new build?

According to Home Builders Federation (HBF) recent analysis of EPC ratings, 85% of new builds have an A or B rating with just 4% of older properties achieving the same energy-efficient grade. They've also calculated average savings of  £3,100 annually on energy bills (equivalent of £258 a month), when the Energy Price Guarantee (EPG) increases on 1st April 2023.

Why does an older property cost so much to run?

There are lots of reasons why older homes cost more to run - and they can often make some of the more endearing qualities of old-world charm rather less appealing.

An older home is usually filled with long-since outdated plumbing systems, old wiring, windows which let heat out and draughts in, and roofs with missing or loose tiles and poor insulation. They can also experience damp.

Like anything over time, the older a home is, the more problems can start appearing. Generally, the older the home, the more time you’ll need to spend on maintenance and, because of its age, parts and materials might be obsolete or difficult to acquire, so it could cost you more.

And if it’s its character you crave, you can find a new home that still offers traditional craftsmanship and period style features, like those of our Heritage Collection, inspired by Arts and Crafts architecture.

How can I bring my old home up to today’s standards?

Many people would rather stay put and do up their home - but it’s not without its hassles.

Renovating an older property can be costly - there’s usually a kitchen and bathroom to modernise and upgrade, an en-suite to add, a new roof, doors and windows, installing a new boiler and central heating system, re-wiring and decorating.

According to the HBF #WattASave report, renovating a three-bedroom semi-detached house to modern standards could cost more than £70,000. And that’s just the physical cost - not factoring in the search for a designer and architect if you want internal reconstruction work carrying out, getting plans and building regulations approved, finding a reliable builder - and living with all that mess while the work is carried out.

Even with a strict budget, don’t be surprised if it ends up being more. Old houses come with surprises, and hidden issues can often make costs soar further.

What can I do to reduce my bills and help tackle carbon emissions? 

Whether you’re in an older home or a brand-new property, you can always find ways to reduce running costs and cut back on bills.

  • Turning your thermostat down by just 10-15% for eight hours a day can lower your annual heating bills by up to 10%
  • Reduce your boiler flow temperature to 75°C (or even 65°C in summer) to save energy instead of the standard 80°C
  • Make sure laundry loads are full and wash clothes in cold water whenever possible
  • Dry your clothes outside in the fresh air, instead of using a tumble dryer (remember, if the ground is dry, your clothes will dry)
  • Make sure your light fittings are energy efficient and switch the lights off in rooms you’re not using. 
  • Cook smart - put lids on pans, only boil as much water in the kettle as you need and heat food in the microwave as it uses less energy than the oven.

How does energy efficiency help the environment?

Energy efficiency means using less power to perform an action such as switching on and using a light, or to provide a service such as heating water.

Homes that use energy supplied from fossil fuels are responsible for significant emissions of carbon dioxide, and the race is on to reduce them and tackle climate change.
