The National Trust Green Energy Fund - bringing renewable technology to National Trust sites

The National Trust Green Energy Fund was set up in 2007 as part of National Trust Green Energy, in partnership with npower. To date, twenty seven of the National Trust’s historic properties have benefited from the fund, and a wide range of green measures are being installed at properties across England and Wales.

These renewable technologies include the installation of solar water heating systems and the replacement of oil powered heaters with biomass boilers, which use material from trees on local Trust estates wherever possible. It is estimated that these measures will save 699,869kg CO2 over the lifetime of the technologies.

Commenting on the scheme, the National Trust’s Director General Fiona Reynolds said:

This is an exciting project for the National Trust. Thanks to npower the National Trust Green Energy Fund is helping us show that historic properties and contemporary renewable energy generation go hand in hand.


Read our case study from Morden Hall

Case study: Morden Hall

Morden Hall Park, in South West London, was the first property to benefit from the National Trust Green Fund. In April 2008 ground and air source heat pumps were installed at this tranquil historic park just outside central London.

A 50 tonne crane was needed to lift boring equipment over the moat and drilling equipment was on site for five days whilst the technology was installed. The facilities at Morden Hall Park now run on renewable energy, significantly reducing the carbon component of the site’s environmental footprint. The functioning of the new system will be on display for visitors and the schoolchildren who use the nearby Snuff Mill Education Centre.

This new technology is generating hot water and heating for the onsite shop whilst being sensitive to the local environment. Within weeks of installation, the property saved hundreds of pounds worth of gas, a saving that is likely to double over the winter months.

Zoë Colbeck, Property Manager of Morden Hall Park, explained the significance of the work:

We are delighted to be the first National Trust site to benefit from the partnership. This will complement the other energy saving devices we have onsite and will enable us to show visitors that we are determined to make a difference and reduce our carbon footprint, whilst at the same time hopefully inspire people to see what energy saving measures they could do at home.

What is the Green Energy Certification Scheme?

In February 2010 a new green certification scheme was launched, in line with Ofgem’s Green Supply Guidelines, to label green energy tariffs (certified by an independent panel of experts) as having genuine environmental benefits and going the extra mile to reduce carbon emissions.

How does it work

npower matches every unit of normal electricity that you use and feeds the same amount, generated from renewable sources, into the electricity network.

When you choose National Trust Green Energy for your electricity supply, npower donates £15 to the National Trust Green Energy Fund, which invests in low carbon initiatives at Trust sites. The National Trust Green Energy Fund will also receive £15 every year thereafter as long as you remain a customer of National Trust Green Energy.

Plus, if you are a National Trust Green Energy customer and also sign up for npower gas supply, we will donate an additional £15 to the National Trust Green Energy Fund and £5 every year thereafter as long as you remain a customer of National Trust Green Energy. The Fund is used to invest in low carbon initiatives at National Trust properties in England and Wales. These projects have included replacing oil fired boilers with biomass ones and installing air and ground source heat pumps.

This tariff is available on a variety of payment methods including Direct Debit, cash, cheque or pay as you go if you have a prepayment meter.

Where our electricity comes from 

At npower we produce and source electricity for all our customer needs. As part of our supply commitment, OFGEM, our regulatory body requires us to provide details of where the fuel comes from that is used to make our electricity, achieving compliance to Electricity Supply Licence Condition 21.

The table below applies to npower customers, supplied under the following Electricity Supply Licenses: Npower Ltd, Npower Yorkshire Supply Ltd, Npower Northern Supply Ltd and Npower Direct Ltd.

Between 1st April 2010 and 31st March 2011 the electricity npower supplied was from the following fuel sources.

Green Energy Certified Fuel Mix

The weighted average of Carbon Dioxide emitted in the production of electricity from each fuel source was: 509 grams per kWh.

The radioactive waste, being fuel burnt in the reactor to be subsequently discharged as spent fuel, is 0.0001 grams per kWh.

This figure has been calculated on the basis of information provided from the DECC (details of these can be found at the DECC website).

Terms and Conditions

Where customers pay by monthly Direct Debit: With National Trust Green Energy your monthly Direct Debit payments will be calculated to include the annual Direct Debit discount, on the assumption you will meet the conditions of those discounts set out on this page.

If for any reason you do not meet the conditions you will not receive the Direct Debit discount and your monthly payments may not be sufficient to meet your estimated consumption. As a result you may have a debit balance to pay.

Electricity 100% matched from renewable sources: The electricity you receive remains the same. Usage is estimated until year end when annual consumption data is checked and we confirm the correct amount of renewable energy has been purchased and fed back into the network. Based on npower's standard tariff. Non-standard tariff customers will be required to move to standard tariff which may be higher than your current tariff.

Your annual Dual Fuel discount: If you pay by Direct Debit continuously for 12 months (either by making monthly payments or by settling your quarterly bill in full by variable Direct Debit) we’ll give you a discount off your bill (£100 if you buy both electricity and gas, £50 if you buy just gas or £40 if you buy just electricity). Alternatively, if you pay for both fuels for 12 months by cash or cheque, either when you receive your quarterly bill or by regular monthly or fortnightly payments, we’ll give you a £10 Dual Fuel discount. Your discount will be credited to your account on or before the last day of the 12th month after becoming eligible and then on or before the same last day of each year you continue to pay this way. Dual fuel customers must pay for both fuels in one combined payment and accept a combined dual fuel bill or statement to receive a Dual Fuel discount. Certain tariffs are excluded. Subject to change.

£15 donation to the National Trust Green Energy Fund: Initial payment of £15 per fuel invested in low carbon initiatives for customers entering into a residential contract with npower for National Trust Green Energy electricity, once supply by npower has commenced. £15 per National Trust Green Energy customer and £5 per npower gas customer invested in low carbon initiatives at National Trust properties will be payable every year a customer stays with National Trust Green Energy for the duration of the National Trust and npower alliance.
