Vaillant Boiler Servicing

A yearly service helps keep your boiler working safely, efficiently and reliably throughout the year. During a Vaillant service, we:

• Inspect ignition and burner performance

• Clean internal components where needed

• Check seals, flues, pressure and system circulation

• Test safety controls and heat response

• Identify early signs of wear before faults become costly

This supports consistent heating, stable hot water, and lower running costs.

Vaillant Boiler Repairs

If your Vaillant boiler is losing pressure, making noise, or failing to heat the home properly, we provide clear, structured fault diagnosis to find the root cause. We focus on resolving the issue in a controlled, reliable way — not just patching symptoms.

Common Vaillant issues we resolve include:

• Intermittent hot water or fluctuating temperature

• System pressure loss or leaks

• Fault codes / lockouts

• Slow or uneven radiator heating

• Unusual internal noises

We ensure any replaced components are compatible with your model and specification.

Replacement Vaillant Parts

Where parts need replacing, we use model-appropriate, manufacturer-approved components.

Typical Vaillant components we replace include:

• Pumps and diverter valves

• Expansion vessels

• Heat exchangers

• Pressure relief valves

• Sensors, thermostats and PCB control boards

Replacing the correct part at the right time helps extend boiler lifespan and restore efficiency.

Vaillant Boiler Installations

If your boiler is older, struggling, or no longer cost-effective to repair, we provide clear advice on suitable replacement Vaillant boilers for your property size and water system.

When installing:

• The old boiler is removed carefully

• Pipework and connections are checked and adjusted where necessary

• The new system is balanced and tested

• Controls and settings are explained clearly

The goal is a steady, reliable installation with no disruption to your home.
