Save money and the planet with solar hot water

Here at Lewington’s, we’ve been installing solar hot water panels since we first launched our Lewington Renewable division back in 2000. Over 20 years on, we have a Worcester Bosch Environment award for our work with renewable systems.

As well as solar hot water system installation, we also carry out solar panel servicing and repairs. Using renewable systems reduces your energy bills while protecting the environment. Not only that, you can even get money back from the government for installing these sustainable technologies. In our opinion, it’s win-win!

“We’re really proud to be endorsed by Which as being a Trusted Trader. To become one of only a select few within our area is testament to our commitment to providing a friendly, efficient, and cost-effective service to the homes within the Leicestershire area.”


Solar hot water system installation enables you to capture heat from the sun to heat your water, lowering your carbon footprint while also saving you money on energy bills!


Solar water heating systems, also called solar thermal technology, use panels on your roof to collect the heat from the sun which is in turn used to heat your water. Solar thermal can be used alongside a regular immersion heater or boiler, which will kick in when your solar supply runs out. The more water you can heat by installation of a solar water heater, the less money you’ll spend on hot water bills.

Solar hot water installation involves adding panels to your roof. These panels capture the heat from the sun, decreasing the burden on both the environment and your pocket! In the summer, when it’s hottest, they can even become your sole hot water supply.

Whilst installation of a solar hot water system is an investment, it’s one that will prove beneficial very quickly. Most homes use up to 25% of their total energy output heating water. This means solar thermal technology can save you hundreds of pounds a year on energy bills.

Solar thermal technology works by passing fluid through small silicon or copper tubes that are attached to a flat, dark glass panel. This glass panel is attached to your roof, where it traps the sunlight like a greenhouse. As the fluid passes through the thin tubing, it absorbs the heat from the panel. This hot liquid is then pumped through your hot water tank, giving you a renewable source of hot water for your home.


Solar hot water system installation comes with many great benefits. These include:

  • Reduced carbon footprint
  • Lower energy bills
  • 0% VAT rate
  • Generates free hot water for a proportion of the year
  • No pollutants
  • Low maintenance

    Whilst there are no grants currently available for Solar hot water, those who invest in solar heating panels are eligible for the reduced VAT rate. The VAT rate applicable to the installation of energy saving materials and technologies will be reduced to 0%, from 1st April 2022 until 31st March 2027.

    The installation of solar panels and equipment on residential buildings and land may be ‘permitted development’ with no need to apply to the Local Planning Authority for planning permission. There are, however, important limits and conditions. You should discuss with the Local Planning Authority for your area whether all of the limits and conditions will be met.

    Most likely, the solar fluid is fed through a secondary coil within your hot water tank to heat the water around, similar to how your boiler would heat.

    Ideally you have a south / southeast facing roof to mount the panels with approximately 6 square meter of space. Flat roofs are an option with specially made mounting frames to create the perfect angle towards the sun.
