Boiler & heating maintenance
An annual gas boiler service is essential to keep your heating system running safely, efficiently, and reliably. Over time, boilers can develop faults, become less efficient, or even produce dangerous carbon monoxide. Regular servicing helps to:
Ensure your boiler is working safely
Prevent breakdowns and costly repairs
Maintain energy efficiency and reduce bills
Keep your manufacturer warranty valid
Extend the life of your boiler
Power flushing
What Is a Power Flush and Why Should You Consider One?
A power flush is a deep clean of your central heating system that removes sludge, rust, and debris from your radiators, pipes, and boiler. Over time, these unwanted materials build up and can cause:
Cold spots on radiators
Noisy or inefficient boilers
Reduced heating performance
Higher energy bills
Potential breakdowns
Using specialised equipment, we flush your system with powerful cleaning chemicals to restore optimal flow and efficiency. The result? Hotter radiators, better boiler performance, and a longer-lasting heating system.
It’s especially recommended before installing a new boiler or if your system hasn’t been cleaned in many years.
Low mains pressure water boosting
How to Boost Low Mains Water Pressure
Low mains water pressure can be a frustrating issue, leading to weak water flow from taps, showers, and appliances. There are several reasons why water pressure might be low, including old plumbing, a drop in the mains supply, or issues with the water company’s system. However, there are ways to improve it.
Solutions to Boost Low Mains Water Pressure:
Install a Water Pressure Booster Pump
A booster pump is a great solution if the pressure entering your home is low. These pumps can be installed on the incoming water supply line and increase the water pressure throughout your home, improving flow in showers, taps, and appliances.
Fit a New Pressure Regulator
If your home has a pressure-regulating valve that’s set too low, adjusting or replacing it can restore proper pressure levels. This is often the case in properties where pressure has been manually controlled to reduce strain on plumbing.
Upgrade Old or Blocked Pipes
If your property has older, narrower pipes, they may be contributing to low pressure. Replacing or upgrading these pipes can improve flow and ensure your system is running efficiently.
Check for Leaks
Better flow for showers, taps, and appliances
Improved washing machine and dishwasher performance
More consistent water delivery throughout the home
Better pressure for garden hoses or outdoor taps
If you’re experiencing low water pressure, we can assess your system and recommend the best course of action, whether that’s installing a booster pump or making repairs to your plumbing.
