Before We Arrive

We’ll confirm your booking in advance, and typically arrive between 8:00–9:00 AM. You don’t need to prepare much — just make sure we can easily access:

The existing boiler and flue
Your gas meter and stop tap
Radiators (if any are being updated)
We bring dust sheets, protective flooring, and clean-up tools so we leave your home exactly how we found it — or better.

 
Removal of the Old Boiler

We start by safely isolating your gas, water, and electrical supply before removing the old unit. Many Tunbridge Wells properties still have older systems — from ageing combis to back boilers — so we take care to plan each job around your setup.

 
Pipework Adjustments

If you're upgrading to a modern boiler, we may need to:

Upgrade your gas pipework to 22mm
Reposition flues or reroute condensate pipes
Make layout changes to improve system efficiency
You’ll already know in advance what we’re doing — we explain everything clearly during the quote stage, so there are no surprises on the day.

 
Installing the New Boiler

We mount and connect your new boiler — usually a Worcester Bosch, unless you’ve chosen another brand. We also install:

Smart thermostats or wireless controls
Magnetic system filters
TRVs and lockshields
Optional scale protection depending on water quality
Cristina often works alongside me on installations in Tunbridge Wells — she assists with lifting, prep, and layout so the job runs smoothly and efficiently.

 
Commissioning and Testing

We don’t just switch it on and leave. Before we go:

Full Gas Safe commissioning is completed
We do tightness testing and combustion checks
The heating and hot water systems are balanced and tested
You’re shown exactly how to use your new controls
We also notify Gas Safe Register and register your boiler’s warranty directly with the manufacturer.

 
Clean-Up and Aftercare

We vacuum, pack away materials, and take away rubbish. You’ll receive:

A digital or printed certificate of installation
Our direct number in case anything needs adjusting
A reminder to book your first annual boiler service in Tunbridge Wells
