Let's Dive In...

Proudly supporting EHAAT this festive season

Instead of sending client gifts this Christmas, Data Energy donated the money we would have spent to Essex & Herts Air Ambulance (EHAAT), a charity that delivers hospital-level critical care wherever it’s needed, when every second counts.

We’re aiming to fund two life-saving missions (£2,800 each), and we’d love your support. Every donation helps keep this incredible service flying.

More festive fundraising fun

To help boost our EHAAT fundraising total, the team decided to add a bit of festive fun into the mix.

Our sweetie-jar challenge and mystery-elf game brought out everyone’s competitive side. There were plenty of confident guesses, some questionable sweet-weight maths, and a lot of laughter throughout.

By the end of the day, the games raised £179.40, nudging our overall EHAAT total to £2,836.00 so far.

A huge thank you to everyone who joined in, and if you’d like to support EHAAT too, you can donate using the QR code.

Fund 100 missions, save lives this Christmas.

EHAAT needs your help to fund 100 life-saving missions, one for every person who may need
us over the festive season.

15 New Year's Resolutions for Property Managers

On the Road with TPI

One of the highlights of our year has been meeting so many of you across the UK and hearing, first-hand, what’s happening on the ground.

From Manchester and Newcastle to Birmingham, Southampton and London, the TPI Regionals were a real high point for us.

The sessions The Heat Is On - delivered by Jess Warwick and Kat Baker. They were designed to be:

Practical
Fast-paced
Actionable straight away

And the questions and conversations at each stop have directly influenced what we’re building next.

Between Sessions at TPI London

For us at DMG, exhibiting at TPI London Regional this year gave us a valuable window into the real challenges property managers are dealing with day to day.

From emergency callouts and ageing plant to performance issues, many of the conversations at the DMG stand centred on keeping systems running reliably, not just ticking compliance boxes.

Some came over with specific plant-room questions, others to sanity-check an issue they were already firefighting. Those practical discussions around maintenance, risk and response times are shaping how we support clients - from clearer guidance and training to more proactive, preventative approaches.

Thanks to The Property Institute for having us, and to everyone who stopped by the stand. The conversations were honest, practical and exactly what these events should be about.

The PMA's 2025

We had a brilliant evening at the 2025 Property Management Awards, joining more than 1,100 people from across the sector to celebrate the work, innovation and people driving residential property management forward.

Representing Data Energy and DMG Delta, we hosted a table of clients for the night, with Sian, Jess and Kirsty welcoming guests and enjoying a night full of great conversations, familiar faces and a few new ones too.

The atmosphere was buzzing from start to finish - a real reminder of how much good work is happening across the industry. Huge congratulations to everyone who was shortlisted, highly commended or took home an award. The standard this year was seriously impressive.

It was a fantastic chance to step away from the day-to-day, catch up properly and celebrate what makes this sector so strong. We’re already looking forward to doing it all again next year.

The Playbook: making compliance clearer

If you haven’t seen it yet, our Heat Network Compliance Companion Playbook is live and already getting great feedback. It’s designed to help you move from “overwhelmed” to “on top of it”, fast.

It maps the full regulatory journey into four simple, practical steps:

Meter it. Bill it. Maintain it. Manage it.

Inside, you’ll find a clear, interactive guide to compliant metering, billing, maintenance, handovers and resident communications, without the jargon or the waffle.

It’s not a static document, we keep updating it as new information is published, including the latest Ofgem consultation published 3 November 2025).

We’ve created a summary of The 25 Authorisation Conditions which you can access here, as well as our:

^{Some of The Big Questions We've Been Asked This Year}

If you’ve asked any of the questions below - read on to find out how we'll support you to get the answers you need. From more practical tools, insights and updates to bespoke training and our new podcast - find out what we have in store for 2026.

Answers to your Questions

Here are the first three. Tune into our new podcast series, launching next year for more answers and insights.

Do I run a heat network?

If you have a network of pipes that runs through the building and delivers heat, hot water or cooling to more than 1 end user then you are running a heat network.

In practice, this looks like having generation equipment - like large gas boilers in a plant room, chiller units, or even Air Source Heat Pumps on the roof. Some other giveaways are large utility bills for gas or electricity, or historical apartment-level billing.

Who is the Heat Supplier?

The Heat Supplier is defined by Ofgem as the person or organisation responsible for supplying heating, cooling or hot water to heat network customers through a heat network.

They are typically the entity that holds a heat supply contract (or equivalent agreement in the lease) with consumers for the supply of thermal energy via the network. It’s likely that the building’s freeholder is the Heat Supplier.

Why aren’t the billing agents the Heat Supplier?

The Heat Supplier is the organisation that holds the heat supply agreement with end users.

In most cases, this is not the billing agent. The agreement usually forms part of the lease between the Freeholder and Leaseholder, with the Freeholder also responsible for the incoming utility supply and for generating the heat itself.

Making Support Simpler

Talk to Us

Better insight, better efficiency (and better readiness for regulation)

Our partnership with Guru Systems

This year, we officially partnered with Guru Systems, the industry leader in heat network performance monitoring and analytics.

Why it matters now: As regulation tightens, it’s getting harder to rely on gut feel or reactive maintenance. You need clear, trusted data that helps you understand how your network is performing and where the risks are, so you can take action early and show progress with confidence.

By combining Guru’s award-winning hardware and analytics with our own expertise in compliance, data collection, and billing, we’re delivering a complete, integrated solution - giving our clients the visibility, confidence, and control they need.

Meeting new heat network regulations just got easier

Data Energy X Guru Pinpoint

Performance monitoring you can actually use:

Clearer visibility of how the network is behaving day to day, not just when something goes wrong.

Earlier issue detection:

Spotting losses, anomalies, and underperformance sooner - before they become resident complaints, emergency callouts or big bills.

Stronger evidence for decision-making:

Better data to support prioritisation, investment planning, contractor conversations, and internal reporting.

A smoother route to compliance:

Monitoring and performance insight that helps you demonstrate control, transparency, and continuous improvement as expectations evolve.

2026: Bespoke Training

Understanding Heat Networks

Alongside our roadshows, we also run bespoke training sessions designed around the real questions and challenges you’re facing. One example is our:

Heat Network Foundations course - a practical walkthrough of everything a Property Manager needs to know, including:

How heat networks work (energy centres, primary & secondary networks)
What the new regulations mean in practice
Roles and responsibilities: Operator vs Supplier
Metering essentials, and what to do when coverage is incomplete
Billing, tariffs, debt management, and resident engagement
Complaints, vulnerability protections, and continuity of service
Maintenance, O&M documentation, lifecycle planning and emergencies

Get in Touch

We break complex requirements into clear steps you can apply across your portfolio, with real-world examples and time for Q&A.

If your team would benefit from a tailored session - whether it’s a foundations course, a deep dive into billing, or a workshop on compliance readiness - we can shape the content around your needs.

^{WHAT'S COMING}

^{The Big d-Analysed Wrap Up}

As we wrap up the year, I wanted to share a quick reflection on what’s been happening across heat networks.

This space has become my way of stepping back from the day-to-day engineering work and looking at the bigger picture: what we’re seeing on site, the questions coming in from clients, and the wider shifts happening across the sector. I’ve really appreciated the engagement this year – especially from those of you asking the harder questions about legacy networks and how we can genuinely improve them, not just keep them running.

Daniel Davies, Technical Project Consultant - Data Energy

We’re expecting ongoing Ofgem updates, plus the much-anticipated draft of HNTAS for legacy networks. Once that lands, many long-standing systems will be assessed against a consistent, technical and data-led standard for the first time. For anyone managing older networks, that’s a big moment – and a positive one. It gives us a clearer framework for what “good” looks like and a chance to lift performance where it really counts.

From my side, I think 2026 is going to be the busiest – and most worthwhile – year yet. Not just because of regulation, but because we’re finally seeing a real shift towards transparency, performance and accountability across the whole sector. Legacy sites, which have often been overlooked, are now right at the centre of improving efficiency, fairness and long-term outcomes for residents.

Thanks to everyone who’s been part of d-Analysed this year – whether you’ve read along, sent questions, or (politely) told me I’d missed a point. Keep it coming. I really do appreciate it – and it keeps me on my toes. Here’s to another year of progress, a bit of healthy debate, and continuing to make heat networks work better for the people who rely on them.

AND FINALLY

A Few Words From Sian and Rupert

This year has been shaped by real conversations with property managers - at events, in meetings and day to day. The Playbook, the roadshows and the tools we’ve built all come directly from those discussions, backed by teams internally who genuinely care about doing the right thing. As we head into next year, our focus stays the same: listening first, supporting properly, and making things clearer and easier where it really matters.”

Sian Hoddle, Director of Energy Services - Data Energy

As the year comes to a close, I want to thank the property managers who continue to trust us across everything they’re juggling - from emergency callouts and day-to-day maintenance to the growing demands of compliance and regulation. Our role is to be there, consistently and reliably, whatever the situation. That commitment from our teams, and the loyalty of our clients, is what really defined this year and will continue to steer us into the next.

Rupert Mackay, Managing Director - DMG Delta
