  Edit: 25/8/2026 Purely because I can't seem to add a second Google Review, I'm editing my first one.  We had a heat pump installed in our house at the end of July, and the Gas Tech team was brilliant.  Tom came to do a survey to start with, to make sure that the system he installed would be the right fit for our house, and for the week a bit for the installation, he and the team worked tirelessly to get everything done.  The system works brilliantly for the hot water (haven't needed the heating yet!), and they've been very prompt with any questions that we've had. Previous review: Once again, the team at Gas Tech Heating team has come through!  Tom came this morning with a new sensor for the boiler, installed it, and make sure everything was all in good working order.  It is so nice to know that they are kind and reliable should anything go wrong with the heating and plumbing in my house.

  Having dealt with 3 different plumbers/heating engineers and 2 new combi boilers in 3 years and still had no water pressure, I was at the end of my tether.  Other companies just wanted money upfront for everything with no results. I asked round my neighbours for companies they’d personally dealt with and Gas Tech Heating was recommended by several people. Tom came round and quickly identified the problem (without any demands for payment in advance) and arranged to carry out the remedial work. This was done professionally by Toms father who arrived promptly and kept me informed what he was planning to do. I wish I’d found this company sooner. Fiona Macdonald.

  Tom did a great job, was thorough and diligent and cleaned up afterwards. They operate an old school style approach which is absolutely perfect in these times when you are searching for trustworthy tradesmen. We would be happy to recommend Tom and his team.

Checkatrade information for Gas Tech Heating Ltd

What is a gas safety certificate?

A gas safety certificate, or Gas Safety Record to give it its official name, is a document issued by a Gas Safe registered engineer following a safety inspection of gas appliances. It is a legal requirement for landlords and businesses to have regular gas safety checks.

A gas safety certificate usually lasts for a year. Regular gas safety checks help to prevent serious health and safety concerns like carbon monoxide poisoning. Even if you aren’t required to have Gas Safety Records by law, it is still a good idea to check the safety of your boiler. When you have a new boiler installed, this will come with the necessary documentation to prove it has been installed safely by a Gas Safe registered engineer.

Landlord gas safety certificate

As a landlord, you will need a gas safety certificate by law. To gain your landlord gas safety certificate, you will need to have your gas appliances inspected annually to ensure they’re safe. This protects your tenants and is a very important part of your legal obligations when renting out a property, either as a landlord or letting agent. We will be happy to arrange a convenient time for your inspection and will issue your certificate immediately upon satisfactory completion. We work throughout Hemel Hempstead and the surrounding areas and can liaise directly with your tenants if this is easier for you.

We will be happy to complete a domestic check and issue a homeowner gas safety certificate to help you through the process of selling your home.

Commercial gas safety certificate

All employers are legally obliged to ensure gas appliances are safe. This is for the safety of employees, customers and anyone else in the vicinity, and it is an important part of preventing serious issues such as gas explosions and carbon monoxide poisoning.
