Boiler/system Servicing and Repair

Regular maintenance and servicing of your boiler and central heating system will ensure the boiler is working safely, save you money on your fuel bills, and reduce the risk of potentially costly breakdowns. All manufacturers recommend your boiler is serviced every 12 months.

During a service we will:

  • Carry out a visual inspection of the boiler to ensure in complies with current regulations.
  • Remove the boiler case and check components for gas/water leaks or heat damage.
  • Clean the combustion chamber, burner and injectors where necessary.
  • Reassemble and run the boiler. Check safe operation of the fluing and ventilation, check the burner pressure/gas rate and carry out a combustion performance check with an Electronic Flue Gas Analyser.
  • Check the system electrical supply fuse and correct operation of the system controls.
  • Carry out an inspection of your visible pipework, radiators and hot water tank.
  • Supply a Service/Maintenance checklist either in paper form or electronically via email.

We service and repair all makes and models of domestic gas boilers, including back boilers and specialise in fault finding on system electrics and controls.
We are happy to give advice and often solve problems over the phone, making a callout unnecessary.

Part of our job is to ensure your boiler or system is working at its maximum efficiency, which in turn will reduce your energy consumption and ultimately, your bills.
With this in mind, if our engineer feels your system would benefit from an improvement or upgrade, he will make you aware of it, explain fully why he feels you would benefit and provide a no obligation quote for the recommended work.

Peace of Mind

Programs like Rogue Traders and Cowboy builders have highlighted some unscrupulous companies and individuals in our industry.
Because of this DIAMOND have introduced a second opinion service called "Peace of Mind". If you have had a diagnosis from another company or individual and you are not entirely happy that it is correct, or the price seems on the high side, we will send one of our qualified engineers to assess the work and give you a FREE second opinion. All we ask is you provide us with a written diagnosis or estimate from the other engineer outlining the work required.
It is early days for the service but we are finding that on average 2 out of 10 of the initial diagnosis were incorrect, and with minor repairs, many systems or appliances went on to work normally.

If you would like more information on the services we provide, or advice about your Plumbing or Heating system, please don't hesitate to give us a call or you can complete our online callback form and one of our friendly, knowledgable staff will call you back at a time to suit you.

We look forward to your call.
