Three Easy Ways to Save Water

With most of the world thinking increasingly about carbon footprints and the impact of our actions on the world, it is clear that small changes make a big difference. From ditching the single use plastic to switching appliances off at the mains, every little effort adds up. Saving water isn’t just better for the environment, it can help to reduce your water bill, too. Here’s what you need to know.

With most of the world thinking increasingly about carbon footprints and the impact of our actions on the world, it is clear that small changes make a big difference. From ditching the single use plastic to switching appliances off at the mains, every little effort adds up. Saving water isn’t just better for the environment, it can help to reduce your water bill, too. Here’s what you need to know.

Water butts

Whether you are a green-fingered pro, or you are struggling to keep a few plants alive, if you have ANY plants that you water, it is worth considering investing in a water butt. When a garden hose is switched on it uses about 15 litres a minute. So if you spend 10 minutes watering the garden, you will blow about 150 litres of precious water! Rainwater is free, has the right PH for Mother Nature, and will allow your garden to thrive even if there is a water shortage. There are a range of rain harvesting solutions available, from basic water butts to roof-mounted systems. If you are worried about installation, check with your local handyman first.

Saving per day – 150 litres

The shower timer

Whether you have shower-loving teens or you secretly know that you are the culprit, showers use a huge amount of water. Showers use on average 10-12 litres of water per minute. So if you are in the shower for 10 minutes, that is a whopping 120 litres – multiply that by four, a shower-loving family could use 480 litres every day! By cutting your shower by just two minutes, a family could save 64 litres of water a day – which works out at a staggering 35,040 litres in a year.

Saving per day – 64 litres

Flush if you must...

We all know that toilets use a huge amount of water. There is no need to leave a toilet unflushed all day, but if your family has a habit of throwing a bit of toilet roll and tissue in the pan and flushing it away, that is a habit that you can nip in the bud straight away. Modern toilets use a massive 13.6 litres per flush, with modern ones using a more conservative 6 litres. If we take an average of 10 litres per flush, each family reducing their flushing by one flush per day could save 40 litres in total.

Saving per day – 40 litres

Fix that drip

You have heard the saying “an ocean begins with the first drop” well, your leaking toilet or sink could be wasting an entire ocean. It may seem like an insignificant drip, but a toilet leak could waste as much as 200 litres of water every day, while a leaking tap can waste 21 litres – that’s a lot of drips! If your local plumber charges by the hour, make a list of every drip, crack, leak or problem and get them in for an hour.

Saving per day – 221 litres

If you make one change today, make it one of the above – you won’t just save money, you’ll be doing your bit to save the world. Follow us on Facebook or Twitter for more.

  • Is it worth getting solar panels installed on a UK home?

    Whether solar panels are worth it really depends on your situation. For many UK homeowners they can be a solid long-term investment - payback periods of seven to twelve years are realistic, and you can sell surplus electricity back to the grid through the Smart Export Guarantee. South-facing roofs with little shading get the best results.

    That said, roof orientation, shading, your energy usage, and how long you plan to stay in the property all affect whether the numbers add up for you. It's worth getting a few quotes and running the figures before committing.

  • What is a heat pump and should I replace my boiler with one?

    A heat pump pulls warmth from the outside air (or ground) and uses it to heat your home and hot water - it's more energy-efficient than a gas boiler when properly specified and installed. The key is whether your home is well-insulated. Heat pumps work best in efficient, well-sealed properties. In a draughty house, the benefits are more limited. The Boiler Upgrade Scheme currently offers up to £7,500 in grant funding, so it's worth getting a professional assessment of whether your home is a good candidate.

  • Are there government grants available for home energy improvements?

    Yes. The main ones right now are the Boiler Upgrade Scheme (for heat pumps), the Great British Insulation Scheme, and ECO4 (for eligible households). The details change regularly (eligibility, grant amounts, and which schemes are active) so check directly on GOV.UK or with your energy supplier for the current picture. Just bear in mind that installations need to be done by accredited installers for the grant to apply.

  • How do I know if my home has adequate insulation?

    High heating bills for the size of the property, cold walls and floors, condensation on internal walls, and draughts around loft hatches and window frames are all signs that heat is escaping. A professional energy assessor can survey the property and identify exactly where the losses are happening. Your Energy Performance Certificate (EPC) - if it's up to date - also gives you a useful starting point.

  • What is the Boiler Upgrade Scheme and am I eligible?

    The Boiler Upgrade Scheme (BUS) helps homeowners swap gas or oil boilers for low-carbon alternatives - mainly air source heat pumps, ground source heat pumps, and biomass boilers. As of 2024, the grant is worth up to £7,500 for a heat pump. To qualify, you need a valid EPC with no outstanding recommendations for loft or cavity wall insulation, and the installation has to be done by an MCS-certified installer. Eligibility and amounts do change, so check current terms on GOV.UK before making any decisions.

  • How do solar panels actually work?

    Solar panels are made up of photovoltaic (PV) cells that generate electricity from daylight - not just direct sunlight, which is why they still produce power on overcast days (just less of it). The electricity they generate is direct current (DC), which an inverter converts into the alternating current (AC) your home appliances use. Whatever you generate and use yourself reduces what you draw from the grid. Any surplus can be exported and you can get paid for it via the Smart Export Guarantee, or stored in a battery if you have one.

  • How long do solar panels last and do they need servicing?

    Most come with a 25-year performance warranty guaranteeing at least 80% of rated output - and many systems outlast that. The panels themselves have no moving parts, so they're low maintenance by nature. The inverter is the component most likely to need replacing, usually after 10 to 15 years. Rain generally keeps panels clean in the UK, but a professional clean every couple of years is worthwhile - particularly on low-pitched roofs where debris builds up.

  • How many solar panels does a typical UK home need?

    The average UK household uses around 3,500 kWh of electricity per year. A 4kWp system - roughly 8 to 10 panels - will generate around 3,400 kWh annually in average UK conditions. Smaller households might be fine with 3kWp; bigger homes or those with EVs and heat pumps will want more. The limiting factor is often your roof space, orientation, and shading rather than budget. An MCS-certified installer will model your specific situation and recommend the right size - this assessment really does make a difference to what you get out of it.

  • Why might solar panels not be right for my home?

    There are a few things worth keeping in mind that can affect whether solar panels make sense for your home. A north-facing roof receives less direct sun and will generate considerably less power, and significant shading from trees, chimneys, or neighbouring buildings can also have an impact. Some listed buildings and conservation areas have planning restrictions, so it's worth checking before going too far down the line. Homes that need re-roofing soon, or that have existing structural issues, may also face additional costs that change the overall picture. And if your household electricity usage is quite low, the payback period can extend more than you might expect.
