Exciting News

As of Tuesday 26th April we have rebranded our sister company as AES Compliance & Testing (previously DALTEC). This was launched to our growing teams of engineers at a meeting at The Charlecote Pheasant Hotel, Charlecote, Nr Leamington Spa.

This is an opportunity to streamline the brand and is reflective of our continued growth to create a stronger group identity.

This was the first time we were able to bring the nationwide team of engineers together in over 2 years, and it was a perfect opportunity to discuss changes to Part L and the new Testing standard TM23.

We were also able to share the opportunities that are available to the staff in an expanding company in an exciting dynamic industry.

Time to Talk – building resilience


Colleagues at AES took time out of their busy work schedules last week to participate in Time to Talk Day. It was great to see such engagement from the staff and support from the management team, to talk about mental health issues and share advice, stories and resources.

The idea initiated by Sam Holton, a Graduate Sustainability Consultant, was to identify some of the signs and key triggers of poor mental health and stress and to share and discuss some of the ways of preventing or dealing with these issues.

Sam said “It took me a very long time to approach anyone and it often feels like the last thing you want to do, especially when you’re feeling overwhelmed with work. For me, just getting talking was the hardest part. Help and resources are available if we can get over that initial barrier of opening up. As a team, we have analysed some of the key causes of poor mental health and discussed ways of addressing them. We’ve pooled together some mental health resources and made sure everyone can do something when times get tough.”

Future sessions are being planned for the team to ensure there is always Time to Talk. We have also allocated time for ’virtual’ coffee breaks and plans are underway for more team sessions where we can discuss ideas and build our resilience.

Do you know how to be energy efficient?





Energy Saving Week is a national campaign with the aim to help encourage energy saving measures and cut down on fuel costs. During the current energy crisis with several suppliers failing, it is essential we are all aware of the best ways to reduce energy bills and share information for all to keep warm this winter. The Energy Saving Week event is created in partnership with Citizens Advice, the Energy Saving Trust and the Department of Business, Energy and Industrial Strategy.

The following tips will help save money by saving energy in the home:

Kitchen and bathroom 

  • Take simple steps to save money in the kitchen. You could save around £28 a year by cutting back the washing machine and dishwasher use by one cycle a week, and only filling the kettle with the water you need.
  • Other simple steps you can take in the kitchen include using the right hob size for your pan, keeping lids on pots and pans, cooking food in batches in the oven and eating for lunch/dinner the next day, and leaving the oven door open after cooking to let the residual warmth heat the air around.
  • Ensuring food cools down before putting it in the fridge also helps, as the fridge won’t have to work so hard to cool the food down.
  • Cutting your shower time by just one minute can make a big difference. If everyone in a four-person household with a water meter did this, you could save £50 a year!
  • Switching to a water efficient shower head could save a four-person household with a water meter around £80 on gas and water bills – quite a saving!

Appliances and lighting 

  • Looking for a quick and easy way to save money? Turn your appliances off instead of leaving them on standby – you could save £40 a year, and you’ll be saving energy too.
  • Are you guilty of leaving lights on? Turning lights off when you’re not using them, even just for a few seconds, could save you £14 a year on your bills. It all adds up.
  • If it’s time to replace a lightbulb, go for an LED. Replacing all your bulbs with LEDs would cost the average household around £145, but you’ll save £35 a year on your bills.

Heating and draught-proofing 

  • Feeling a chill? Unless your home is very new, you’ll lose some heat through draughts. Draught-proofing could save you £30 a year on your bills, and your home will feel warmer.
  • Don’t let heat escape through your chimney – installing a chimney draught excluder could save you around £20 a year on your bills and make your home feel more comfortable.
  • More than half of the money spent on fuel bills goes on heating and hot water. Try turning your room thermostat down by just one degree – you could save around £65 a year.
  • It pays to be in control of your heating. Installing and using a room thermostat, programmer, and thermostatic radiator valves could save you around £85 a year.
  • Close the curtains to keep in the heat, and tuck curtains in, especially if your radiators are underneath the windows so that your heating is funnelled into the room.

AES Sustainability Consultants have a team dedicated to improving the energy performance of properties undergoing refurbishment or conversion works who can help ensure that energy and carbon savings are cost-effectively maximised. All the EPCs we produce contain additional suggestions on how to improve the property’s energy performance and therefore reduce bills e.g. through the installation of PV panels, and include ‘typical installation costs’ and ‘typical yearly savings’ to help guide cost-effective decision making.

Please contact AES for advice on your projects.

Building Regulations update – Part L, O and S


In December 2021 the Government published the long-awaited update to Part L, confirming the energy, carbon and fabric standards which will be required once the Regulations are in force. Our summary document provides the key highlights and some commentary on the additional requirements set by the new Part O addressing overheating risk, and Part S setting requirements for electric vehicle charging.

Please contact AES to discuss the implications of these new standards for your development.

An Odd Sock Team Meeting

Celebrating World Down Syndrome Day (WDSD) this year was inspired by one of our staff members, who’s 3 year old son Jesse received a post-natal diagnosis of Down Syndrome at four weeks old.

WDSD occurs annually and presents a unique opportunity for families, advocates, professionals and organisations such as ourselves to both celebrate and raise awareness of Down Syndrome. Down Syndrome also known as Trisomy 21 is a condition where a child is born with an extra chromosome by chance. People with Down Syndrome will likely have a varied level of additional needs, but can and do lead full and rewarding lives.

This year WDSD has sought to highlight a number of issues, including giving people with Down Syndrome the chance to shine through employment. Jesse, like any other child has his challenges, but he is a very happy little chap who brings joy to all and has huge potential. One day when he enters the work place, we can only hope there are employers out there who are willing to give him a chance, like Simone in this fab new video and sung by none other than Sting! ‘The Hiring Chain’ – Take a look! THE HIRING CHAIN performed by STING | World Down Syndrome Day 2021 – YouTube

Here’s how our Odd Sock meeting turned out! Happy World Down Syndrome Day 2021.

MHCLG published their long awaited consultation on overheating in January 2021

The proposal adopts a risk-based assessment which distinguishes between Greater London (Significant Risk) and the rest of England (Moderate Risk). Depending on the fabric elements (glazing exposed to the outside) and the provision of cross ventilation, the ability to limit solar gains and the removal of excess heat must be proven using the simplified methodology. A simplified assessment means that some design restrictions would be applied, or alternatively compliance can be demonstrated through dynamic simulation.

AES Sustainability Consultants have looked at practical examples of what the implications of the simplified method could look like. Outside of London, we do not anticipate any major problems meeting the maximum glazed area. The challenge for the designer will rather lie in the provision of sufficient free area for natural ventilation.

We welcome the proposed new method as it will provide an incentive to address maximum glazing and minimum free area early in the design process but also allow the flexibility to go to dynamic simulation assessment. Please click here for further information on the consultation response.

Our Coronavirus Update

AES Sustainability Consultants has continued to closely monitor the development of COVID-19 in the UK. We aim to keep our customers and our staff as informed as possible.

We want to reassure you, our customers, that we are taking the appropriate action where necessary to ensure continuity of business and maintain our high level of service.

Some of the specific steps we have taken are:

  • We have the technology infrastructure in place for our entire business to work remotely.  This has been tested and worked well during the initial lock down restrictions, meaning we can quickly revert to this way of working should we be required to shut our office again.
  • We have the ability to stay connected using Telephone, E-mails, Skype, Zoom and Teams.
  • All points of contact remain the same.
  • We have reviewed our business to identify critical services and taken steps to secure these (e.g. EPC production for CML).
  • Our staff receive weekly updates.
  • All our site engineers have been given detailed guidance about what measures to take to ensure they minimise the risk of contracting or spreading the virus when visiting sites. They will all comply with any site-specific measures put in place.
  • All our consultants have been requested to work from home until further notice with just the administrative staff working from the office. Our employees know what action to take if they or anyone they have come into contact with have any symptoms.
  • Please note, our office remains open until further notice.

We appreciate that things are likely to get challenging again over the coming weeks but we are prepared and we are here to help. If you have any concerns please do get in touch.

Kind regards,

2019 M3 User Group

Presentation SlideBuilding Sustainable Homes

On Tuesday we took part in the 2019 M3 User Group event at The Crystal, one of the world’s most sustainable buildings, achieving Outstanding BREEAM accreditation and Platinum LEED accreditation. This event was a gathering of social housing providers from around the UK, including development reporting and maintenance professionals.

There were a series of interesting speakers discussing the challenges facing this sector, including our very own Principal Sustainability Consultant, Silvio Junges.

Silvio presented on Building Sustainable Homes and went onto highlight the changes in the Part L consultation document; which will effect all developers but particularly those working in the social and affordable housing markets.

Mike Fisher, Head of Technical at A2Dominion, a fellow panellist, explained how early engagement with AES Sustainability Consultants ensures that cost effective sustainable solutions can be implemented at an early stage and managed throughout the build to ensure compliance and a reduction to the design As-Built performance gap.

If you would like to discuss the proposed changes to Part L, please Contact Us.
