Socket Overload Interactive Tool

Are you worried about sockets overloading?

Do you use extension leads in your home and wonder if too many appliances are plugged in? Why not use this interactive tool to see if your socket can cope with what you are plugging in.

Overloading of any socket is a real danger to you and your home and is one of the main causes of electrical fires in the home.  

Here are some of the common danger signs;
• a smell of hot plastic or burning near an appliance or socket
• sparks or smoke coming from a plug or appliance
• blackness or scorch marks around a socket or plug, or on an appliance
• damaged or frayed leads
• coloured wire inside leads showing at the plug or anywhere else
• melted plastic on appliance casings or leads
• fuses that blow or circuit-breakers that operate for no obvious reason

If you have concerns about your electrical sockets or overloading send us an email at or call on 01722 417873

Celebrating 20 years of AHS

The year is 1999 and major events are taking place.

  • “Y2K” is looming and the associated prediction of IT systems failing and catastrophe (which as we now know was rather inaccurate).
  • The “euro” gets introduced to the worlds financial markets,
  • The Matrix film (the first of the trilogy) is released to huge financial success & critical acclaim.
  • …. and Alexandra Heating Services is launched.

OK, so maybe AHS is not quite headline news compared to the others but to us at AHS it was the start of something big.

20 years on and we have not only grown in both employees and premises.  But also we have broadened our horizons to new areas such as renewables. Along with creating an electrical division.  One thing hasn’t changed, ultimately the customer always comes first! The same attention to detail and professionalism is as important today as it always has been.

And as part of our celebrating 20 years we are delighted to offer new customers an introductory 20% off all servicing. Between 1st July and September 30th 2019. Please quote CELEB2019 when calling 01722 417873 or emailing us.

We look forward to serving the local area for a further 20 years, so if you have heating or electrical needs or want to talk to us about renewable energy we would love to hear from you.

New boiler installation

The office staff and engineers at AHS Ltd are to be highly commended for their friendly, prompt and efficient service. Our old boiler had been condemned during a particularly chilly spell.. The whole team worked together to instal our new boiler quickly and professionally with minimum disruption. I would definitely recommend this company!

New Boiler

What a service! Alan surveyed the job and quoted for the work on a Thursday and installed the new boiler the following Monday. He was extremely knowledgeable and was happy to answer all our questions.

He and his mate had the new system up and running that evening. Their work ethic was a joy to behold. Well done AHS.
