When a boiler and controls upgrade is the right choice

This service is ideal if your boiler is unreliable, inefficient, or no longer economical to repair. It also suits properties where the heating is hard to control, rooms overheat, or you want clearer scheduling and temperature management. Landlords and small commercial premises often choose it to improve reliability and reduce call-outs.

How the installation is delivered

You will usually start with an on-site assessment to confirm suitability, positioning, flue route and control options. Installation typically involves removing the old unit, fitting and connecting the new boiler, then upgrading and configuring the controls so they work correctly with your system. Before handover, the boiler is commissioned, tested, and set up so you can run heating and hot water confidently.

After installation: set-up, guidance and ongoing value

At handover you will be shown how to use the new controls, set schedules and make simple adjustments. You will also receive the relevant compliance documentation and commissioning records. If you choose smart controls, basic guidance on apps and user settings can be provided so you can get the best from the upgrade.

Frequently Asked Questions

Do I need to upgrade my heating controls when replacing the boiler?
Often, yes. Modern controls can improve comfort and efficiency, and a controls upgrade can help meet current UK requirements for boiler replacements. The best option depends on your system and how you use the property.
How long does a boiler installation with controls upgrade take?
Many standard replacements can be completed within 1 to 2 days, depending on access, flue route, and any pipework or wiring changes. You will be advised of the expected timescale once the system has been assessed.
Will the work be Gas Safe compliant and include the right paperwork?
Yes, the installation should be completed to Gas Safe and Building Regulations requirements. You should receive commissioning records and the relevant compliance notification or certificates at handover.
Can you fit smart thermostats or app-based controls?
In many cases, yes. Compatibility depends on the boiler model, existing wiring, and whether you need features like zoning. Options can be discussed during the assessment so the controls match your priorities.
Will my system need a powerflush or magnetic filter?
It depends on system condition and water quality. If there is sludge, corrosion, or persistent cold spots, cleaning may be recommended to protect the new boiler. A magnetic filter is often advised to help reduce future debris and breakdown risk.
