Gas Boiler Installation

We install all types of boilers but we advise customers to fit energy efficient boilers. We provide a guaranteed quote that’s specific to your heating and hot water needs. As every project is different and every customer has different heating and hot water needs, reviewing your needs on your project is the best way to give you an accurate estimate.

How the installation of a new gas boiler system (dependant on property and project type) is assessed:

  • We recommend a type and size specific to the property
  • We assess whether the gas supply needs upgrading? (Does it currently meet legal and safety requirements?)
  • Does the heating need to be re-located or is it a new installation
  • Is there any significant building work required?
  • What and how many appliances are required?
  • Would you like to enhance your system to improve energy efficiency?


We are familiar with all major brands including: Baxi, Broag (Avanta), Glow Worm (Ultracom, Flexicom, Betacom), Ideal (Classic, ICOS, ISAR, ESPRIT, ELISE, Mexico), Keston (Qudos), Main, Potterton (Suprima, Promax, Performa, Gold), Vaillant (Ecotec), Worcester (Greenstar, Highflow) and Honeywell Controls.


Underfloor Heating

We are experts in advising and installing underfloor heating systems.  These systems are designed as a more cost efficient and environmentally friendly way of heating properties.  Warm water from the heat source is circulated through a series of pipes installed and integrated within the floor. Heat is emitted from the floor providing a more comfortable and even temperature throughout the room.  There is a centrally located manifold which controls the temperature in individual rooms via their own thermostat.

District Heating & Energy Centres

District heating is a more efficient and effective means of delivering heat to large scale projects through insulated pipes.  From laying underground pipes to serve district heating services to installing centralised HIUs (Heat Interface Unit) and finally setting up energy centres On Tap Plumbers do it all.


Plant Room Engineering

We offer a range of services for plant room installations, upgrades, fabrication and commissioning.  Our team of skilled engineers will coordinate all the logistics including third party deliveries to ensure a smooth and efficient job.


Power Flushing

If you would like to make sure that your boiler, pipes and radiators are working with maximum efficiency, you need a Power Flush. This may also be the answer to noisy pipes, radiators that are half cold and ensure heating systems last longer.

Gas Boiler Service

It’s sensible to have boilers checked every year. This will help prevent carbon monoxide poisoning and ensure that hot water and central heating are working efficiently.

When we check boilers, we’ll inspect and test all its components, clean anything that needs it and make sure there are no gas leaks.
