Are new build houses more energy efficient?

12-10-2022 Blog

New build houses save homeowners on average £2600 in annual energy bills (HBF, 2022). This article demonstrates why our new build homes are more energy efficient than older builds, helping you to reduce your energy bills and running costs.

The prevention of heat loss can have a huge impact on lowering your energy bills and fostering a better living space during the colder seasons. New build homes are much better equipped for keeping heat inside the house through advanced methods such as double or triple-glazed windows, and internal wall insulation.

Double-glazed windows are crucial to insulation; heat is lost through single glazing around twice as fast as through standard double glazing (, 2016). Our properties at Clarendon Homes all include double or triple glazed windows, to ensure the best insulation for our customers. The internal wall insulation is also superior in new builds because these homes have well insulated cavity walls. This is done by insulating the cavity space between the outside and inside wall, adding an extra layer to keep the cold out and the heat in.

Furthermore, improved insulation has other added benefits, such as being more sustainable by emitting a third of the carbon of an older property (HBF, 2022) and being more effective at keeping external noise out, resulting in a home where you can relax in peace and quiet.

Smart central heating

Modern new build homes have much improved heating systems compared to old builds. This can be attributed to older properties having outdated boilers and heating systems, which are often less energy efficient than new models, in addition to being unsustainable for the environment.

At Clarendon Homes, all our current and upcoming developments are being fitted with Mitsubishi Electric Ecodan air source heat pumps, which have an A++ Energy Rating Level. These electric heat pumps offer a renewable, low carbon alternative to traditional high carbon heating systems. This reliable, renewable heating technology delivers highly efficient sustainable space heating and hot water all year round. Our air source heat pumps also offer the opportunity for smart underfloor heating, which is a cleaner, smarter way to heat your home.

LED lighting

The light-emitting diode (LED) is the most energy efficient lighting technology. High quality LED light bulbs last longer, are more durable, and offer comparable or better light quality than other more common types of lighting. Residential LEDs use at least 75% less energy and last up to 25 times longer than incandescent lighting (classic light bulbs which produce light through heat).

Our developments are all equipped with energy efficient LED lighting, to ensure that our customers have the best lighting available in their new homes.

Wear and Tear

After years of usage, it is natural for any house to suffer from wear and tear. This means that the older the house, the higher the chance that wear and tear has taken place. On the other hand, buying a new build home ensures that you are purchasing your home in perfect condition.

To give you extra peace of mind, Clarendon Homes properties are covered by a 10-year structural warranty from either BLP or Q-Assure, to give you long-term reassurance in addition to our own in house after care service.

Eco-friendly materials

At Clarendon Homes, we strive to use eco-friendly materials to support our sustainable efforts. An example of this is our use of Timber, which is a naturally renewable and sustainable material, especially when compared to alternatives such as brick, and steel. We also use solar panels and have electric car charging points at selected developments, such as Churchfields and Cobnut Park.
