We’re getting ready for Flourish 26 - the three-day gathering organised by our client, the Yorkshire North & East Methodist District. Taking place 13–15 February 2026 at the University of York, the event is all about helping people “flourish” in their faith and community life.

From TODAY, Ofgem’s heat networks regulations officially take effect. This marks a major step: heat networks are now recognised as a regulated utility, with clear responsibilities for operators to deliver outcomes for consumers, meet technical standards, and provide transparent, fair pricing.

Great news for the heat networks sector...

The Heat Network Efficiency Scheme (HNES) has been extended by a further two years, giving owners and operators more time to secure funding for upgrades that improve performance, reduce carbon, and protect consumers.

We’re really pleased to be working with the amazing team at Zero Carbon Harrogate on an exciting new community energy project for Harrogate and Knaresborough.

On this wet Tuesday, the D3A Energy team are carrying out site surveys for a series of Energy Audits across the Darlington Methodist District.

D3A has been appointed by Cumberland Council to deliver a Renewable Energy Technical Feasibility Study for the Port of Workington - supporting its transition to net zero and attracting new investment.

The D3A Energy Team recently visited Wetherby Methodist Church to see the commissioning of their new air source heat pumps and solar PV + battery storage system.

Heat Networks become a regulated utility in 2026

From January 2026, heat will be treated as a regulated utility.
If you manage a communal or district heating network, you’ll need to prepare for a number of changes that could impact how you run your network.

With UK Government ambitions that 20% of all space heating and hot water is fed from Heat Networks by 2050, it’s clear that reliable, efficient systems will be vital to reaching Net Zero.

We’ve always believed that a strong quality management system is key to doing great work but earlier this year, we decided to take that commitment one step further by pursuing ISO9001 accreditation.

We’re excited to introduce Nick Walls, who’s joined D3A as our newest Energy Consultant.

Today Paul Haverson and Joe Thompson headed to Northallerton Methodist Church to join in the celebrations to mark the completion of a £1.1 million decarbonisation project spanning 20 churches across the Yorkshire North & East Methodist District.

Big changes are coming to heat networks and they’re good news for residents. If your heating comes from a communal or district heat network, things are about to improve.

New heat network regulations are coming and here's the big question - is your site ready?

As we sift through the latest draft of the Heat Network Technical Assurance Scheme (HNTAS) standards published by DESNZ, one thought keeps coming to mind - how will the 100s, if not 1000s, of smaller and independent sites navigate this?

What better way to demonstrate the positive effect our team can have on the wider community than a series of Before & After shots?

As the clock ticks toward 2050, one of the biggest climate wins may be hidden right beneath our streets.

This week, we’ve had the pleasure of welcoming Maria Grimes for her Industrial Placement. Maria, a Year 12 student from Queen Elizabeth High School in Hexham, is exploring career paths in Architecture and Chemical Engineering.

Friday marked a big date in the D3A calendar – the 2025 Summer Social. After a brilliant time at Golf Fang in 2023, there was unfinished business and a podium to defend – so we returned, ready to settle the score.

It’s funny how life turns out…

As a child, Ian Williamson, our newest D3A recruit, dreamed of being a fireman. Later, after studying structural drafting, he worked for a manufacturing company where he designed a fireplace that achieved the lowest emissions in the company’s entire product range.

Just over a year ago, the D3A Energy team made their way to the picturesque district of Uttlesford in Essex, where we carried out surveys on a number of council-owned buildings ahead of developing bespoke Heat Decarbonisation Plans.
