Dinefwr Park is set to open its doors for free on September 13 and 14 where visitors will be invited to get stuck into some good green fun.

There will be activities for all ages including behind-the-scenes house tours, explorer trails and the chance to win a year's free supply of electricity.

The historic house and parkland at Dinefwr will be free to enter on Saturday and Sunday, September 13 and 14 for a special Green Living event in partnership with the 100 per cent renewable electricity company, Good Energy, and sustainable energy charity, the Centre for Sustainable Energy.

Visitors are invited to discover the estate's innovative energy scheme and wildlife conservation efforts as they enjoy an estate trail. The day is all about sharing the conservation charity’s sustainability stories and inspiring people to have a go in their own homes and gardens.

Plus visitors will have the opportunity to win a year’s free electricity with Good Energy and take home some energy saving advice.

This event is part of European Heritage Open Days, a European-wide celebration of our common heritage.

Sophie Thomas, Communications Officer for National Trust Carmarthenshire, said: “We all want to make sure this special place can be enjoyed by everyone forever, so we’re careful with our energy, water and waste across all parts of the estate.

“I’m really pleased we can show people at this event the changes we’re making to become greener, and hopefully visitors will see it’s actually easy to do most of these things at home too.”

Charmaine Coutinho, Business Development Manager at Good Energy added: “We’re really excited to be part of the National Trust’s Green Living Days. It’s a great idea to tell visitors about the steps they can take to become cleaner and greener in their own homes – including switching to a 100% renewable electricity company like Good Energy.

The event at Dinefwr is one of many Green Living days happening at National Trust places across England and Wales in September. By sharing sustainability stories and offering guidance, the conservation charity aims to help others discover ways to look after their own homes and save money on energy bills.

National Trust staff and volunteers are now working hard to support the charity’s ambitious energy targets, to reduce energy use by 20 per cent and generate half of its energy from renewable sources by 2020. If these targets are met it will help cut the Trust’s greenhouse gas emissions by 45 per cent and save an estimated £4m each year.

Money saved through the charity’s energy programme will be ploughed back into conservation work across the 250,000 hectares of countryside, 742 miles of coastline and hundreds of historic places that the Trust looks after in England, Wales and Northern Ireland.

Dinefwr is open from 10am to 6pm. Visitors can enjoy free admission all day during opening hours.
