Future Standards Regs

Building standards are changing. We've had the 2021 Building Regulations update, and are working towards the Future Homes Standard in 2025.

Save money

With homeowners keen to reduce their bills to combat the cost of living crisis, insulating homes and finding cheaper sources of energy is crucial.

A brighter future

Protecting the planet for future generations is hugely important. We need to act now to help.

Help to Heat Scheme

Recently, the Government launched a new initiative targeted at boosting the energy efficiency of hundreds of thousands of houses, which was welcomed by industry organisations such as the RIBA and UKGBC.
A public education campaign will accompany the energy efficiency initiative. The new ECO+ initiative will help households who do not currently get any other government assistance in upgrading their houses. This fresh £1 billion investment, which will be added to the existing £6.6 billion 'Help to Heat' energy initiatives, will guarantee that hundreds of thousands more households benefit from new home insulation and, as a result, lower costs.

Ultimately, whether you are building a new home, building a development or simply trying to save money on your energy bills, there is almost always a sustainable option available which can improve your energy efficiency, your Carbon footprint, and the money in your pocket.

Heat Pumps

This kind of energy is freely accessible and is generated by solar energy, which heats the earth and air before being transformed for use in a heating system. In reality, up to 75% of the energy required by the heating system is taken from the environment, leaving just electricity to power the heat pump compressor.


Solar water heating systems rely on collectors, which are mounted on your roof. These absorb solar energy and use it to heat water that is stored in a hot water cylinder. As a backup, a boiler or immersion heater can be used to heat the water to the desired temperature.


Energy-related regulation is always changing, and Howarth Timber & Building Supplies is committed to keeping customers up to speed by offering the most recent variety of energy-saving insulation materials for both newly built and existing homes.


Timber is one of the most environmentally friendly beneficial materials available today, operating as a natural carbon sink and being completely renewable. At Howarth, we ensure that all of our timber products are supplied in a sustainable manner, and you can see proof of this on our certifications page, here.
