Renewable Energy Solutions for a Greener, More Efficient Home

Switching to renewable energy is one of the most effective ways to reduce your carbon footprint, lower your energy bills and future-proof your home. At CP Jefferies, our renewables team designs, installs and maintains a wide range of renewable systems tailored to your property.The best way you can reduce your home's environmental impact is to make the switch to renewable energy.

Renewable energy is harnessed from natural sources and transformed into usable forms of energy such as the electricity that powers your home and EV, or heat that keeps your home warm all year round.

Renewable Energy Solutions for a Greener, More Efficient Home

Solar Panels allow you to generate electricity from the sun which is then used to power your home all year round. You can also store excess power and use it when you need it most by installing a battery storage system.

Heating your home with green energy is another great step towards sustainability. Air Source Heat Pumps (ASHPs) and Ground Source Heat Pumps (GSHPs) are a hassle-free way of consistently heating your home, by extracting heat from outside and moving it into your home's radiators and hot water systems.

Our Renewables Team design, install and maintain a variety of renewable heating and power systems from leading manufacturers including Vaillant, GivEnergy, Mitsubishi and SolarEdge helping you towards your green living goals and a more sustainable future.

Our Renewable Services

Air Source Heat Pumps (ASHP)
A highly efficient way to heat your home and hot water by extracting heat from the outdoor air — even in temperatures as low as -15°C. ASHPs can integrate with your existing heating system and significantly reduce your reliance on fossil fuels.

Ground Source Heat Pumps (GSHP)
A stable, efficient heating solution that extracts heat from the ground using buried pipework. Ideal for long-term efficiency and sustainability.

Solar Panels
Generate electricity to power your home, charge your EV or support your heating system. We install industry-leading systems including SolarEdge and GivEnergy.

Battery Storage Systems
Store excess solar energy to use during the evening, on cloudy days or during power cuts, giving you greater energy independence.

Solar Thermal Systems
Use solar energy to heat your water supply — an efficient, environmentally friendly solution for year-round hot water.

Is my home suitable for a heat pump?

Many homes are suitable, including older properties, but performance depends on heat loss, insulation, radiator sizing, and hot water needs. We start with a survey/assessment to design the right system.

Will I need bigger radiators or underfloor heating?

Sometimes. Heat pumps are most efficient at lower flow temperatures, so some rooms may need larger radiators. We assess each room and recommend the most cost-effective upgrades.

Do heat pumps work in cold weather?

Yes. Modern air source heat pumps are designed to operate in cold conditions. Correct system design and commissioning are key to comfort and running costs.

Do I need planning permission for a heat pump?

Often no, but rules can differ for listed buildings, conservation areas, and certain property layouts. We’ll advise based on your property and recommend checks with the local authority where needed.

Can you help with heat pump grants (Boiler Upgrade Scheme)?

If your project is eligible, we can explain how the grant works and what information is needed. Eligibility depends on your property and current heating, so we confirm details during the survey.

I’m in a listed building or conservation area - can I install a heat pump or solar?

Possibly, but it may need additional permissions. Listed buildings often require listed building consent for external changes, and conservation areas may have extra rules. We recommend an early conversation so we can advise on practical options.

Do you have experience retrofitting older properties sensitively?

Yes. Older homes can benefit from careful upgrades that respect the building fabric. We focus on good design, neat pipe runs, and solutions that balance comfort, efficiency, and aesthetics.

Do solar panels work on cloudy days and in winter?

Yes. Solar generates in daylight even when cloudy, but output is lower than in summer. A well-designed system still contributes meaningfully over the year.

Is a battery worth it?

A battery can increase the amount of solar you use at home by storing excess generation for evenings. Whether it’s worth it depends on usage patterns, export rates, and budget. We can model likely savings and options.

Do I need planning permission for solar panels in the Cotswolds?

Many roof-mounted systems are permitted development, but listed buildings, conservation areas, and some roof types may need consent. We’ll discuss your property and recommend the right next step.

Can I charge an EV from solar?

Yes. Many households offset EV charging with solar, and some chargers can prioritise solar surplus. We can advise on options if you’re planning an EV charger.
