Initial Home Assessment And Survey
Your journey begins with an on-site survey carried out by one of our Gas Safe-registered engineers. This allows us to evaluate:
- Your current boiler setup
- Hot water demand and property size
- Location of your existing system
- Pipework condition and necessary upgrades
We tailor our recommendations based on your heating habits and home structure, setting the foundation for a smooth boiler fitting process in Croydon.
Getting A Clear Quote And Booking Your Installation Day
Once we’ve assessed your home, we prepare a clear and detailed quote. This includes the cost of the boiler unit, pipework, controls, labour, and the removal of your old boiler—no hidden extras.
After approval, we agree on an installation day that suits your schedule. Punctuality and professionalism are guaranteed—we arrive fully equipped to begin work without delay.
Preparing Your Home For Boiler Installation
Before the new system is fitted, we take the necessary precautions to protect your home. This includes:
- Laying down dust sheets
- Isolating water and gas supplies

This preparation stage ensures your home remains tidy and safe while we carry out the professional installation in Croydon.

We ensure all work is completed to current safety regulations. Depending on the complexity, the installation usually takes 1–2 days.

Frequently Asked Questions
How Long Does A Boiler Installation Take?
Most straightforward boiler installations take 1–2 days. If extra work like moving the boiler or adding pipework is required, it might extend to 3 days.
