Before We Arrive

We’ll confirm your appointment in advance and usually arrive between 8:00 and 9:00 AM.

There’s no need to prep the whole house — just make sure we can easily access:

Your current boiler location
The stop tap and gas meter
Radiators, if any are being upgraded or bled
We bring floor coverings, dust sheets, and our own vacuum. Whether we’re working in a newer Crowborough build or a Victorian terrace near the town centre, we always respect your home and clean as we go.

Removing the Old Boiler

Once we’ve laid out floor protection and isolated your gas, water, and power supplies, we’ll carefully remove your old boiler.

In Crowborough, we regularly work in a wide range of property types — from modern estates in Jarvis Brook to older cottages up near Steel Cross — so we’re used to dealing with tricky access or unusual setups.

We drain the system safely, disconnect the unit cleanly, and prepare the area for the new boiler with as little disruption as possible.

Pipework Adjustments

Every installation is different. Depending on your existing setup, we may need to make a few pipework changes to ensure your new boiler runs safely and efficiently.

This could include:

Upgrading your gas pipe to 22mm (common in older Crowborough properties)
Adjusting the flow and return layout for better circulation
Rerouting or extending the flue or condensate pipe
We always explain any necessary upgrades clearly in your quote, so there are no surprises on the day. We’ll make sure everything is neat, compliant, and built to last.

Installing the New Boiler

With the prep work complete, we’ll fit your new boiler. Most of our customers in Crowborough choose a Worcester Bosch model, but we’re happy to install whichever brand you prefer.

We securely mount the boiler, connect all pipework, and make sure it’s set up to manufacturer standards. Where needed, we also install:

Magnetic filters to protect the system
Smart or wireless thermostats
New TRVs and lockshields on radiators
Scale reducers if your home has hard water
Cristina often helps on installation days — especially with carrying tools or materials upstairs — which helps keep the job running smoothly from start to finish.

Commissioning and Testing

This is one of the most important parts of the job — and we never rush it.

Before we leave, we:

Complete the full Gas Safe commissioning checklist
Carry out a tightness test on the gas pipework
Perform a combustion analysis to check everything’s burning correctly
Bleed and balance your radiators
Test both heating and hot water systems thoroughly
We’ll also show you how to use your new controls and make sure everything’s running just how you want it.

Once complete, we register your installation with Gas Safe and activate your boiler’s warranty with the manufacturer — so you’re fully protected.

Clean-Up and Aftercare

We take just as much care cleaning up as we do installing. We vacuum the work area, remove any packaging or debris, and wipe down surfaces — so you’re left with a warm home and no mess.

Before we go, you’ll receive:

Your digital or printed installation certificate
Any warranty or product paperwork
A direct line to us in case you need anything adjusted
A reminder when your first boiler service in Crowborough is due
