What's Included in a Boiler Installation?

What's Included With a New Boiler Installation?

Everything you need for a safe, professional installation

Every BoxHeat boiler installation includes everything required to install and commission your new boiler safely. Your fixed online quote is tailored to your home using the information you provide during our online questionnaire, so you can see exactly what's included before you book.

Unlike traditional quotations that often require a home survey first, our intelligent quote system prices your installation using the details you provide about your property, existing heating system and installation requirements.

After you've booked, we'll ask you to upload photos of your existing boiler and pipework to confirm everything matches your online answers before installation day.

Every BoxHeat Installation Includes

Every installation includes:

✔ Gas Safe installation

Your new boiler is installed by a qualified Gas Safe registered engineer in accordance with current Building Regulations and the manufacturer's installation instructions.

✔ Wireless room thermostat

Every installation includes a wireless thermostat as standard, with smart heating controls available as an upgrade during your quote.

✔ Removal of your existing boiler

We'll disconnect, remove and responsibly dispose of your old boiler as part of your installation.

✔ New magnetic system filter

Every installation includes a magnetic system filter to help protect your new boiler by capturing debris circulating around your heating system.

✔ Chemical heating system flush

Before your new boiler is commissioned, your heating system is chemically cleaned to help remove sludge and debris.

✔ Chemical inhibitor treatment

Following cleaning, your heating system is treated with chemical inhibitor to help reduce corrosion and extend the life of your new boiler.

✔ New flue system

Your installation includes the appropriate flue kit and any flue components identified during your online quotation.

✔ Condensate pipe installation

Any condensate pipework required for your installation is included, together with insulation where required by current regulations.

✔ Gas pipework

Any gas pipe upgrades identified during your online quote are included within your fixed installation price.

✔ Pipework alterations

Any pipework alterations identified during the quotation process are included within your installation.

✔ Electrical connection

Your new boiler is safely connected, tested and commissioned.

✔ Heating system balancing

Where required, your engineer will balance the heating system to help achieve efficient operation.

✔ Carbon monoxide alarm

A carbon monoxide alarm is installed where required by current regulations.

✔ Gas safety testing

Comprehensive gas safety checks and tightness testing are carried out before your installation is completed.

✔ Boiler commissioning

Your engineer fully commissions your new boiler and completes all manufacturer commissioning requirements.

✔ Manufacturer warranty registration

We'll register your boiler with the manufacturer so your warranty is activated, subject to the manufacturer's terms and conditions.

✔ Building Regulations notification

Your installation is notified through the appropriate competent person scheme and you'll receive the relevant certification.

✔ System handover

Before leaving, your engineer will explain how your new boiler and thermostat work, show you how to top up the system pressure if required, and answer any questions.

✔ Clean and tidy installation

Protective coverings are used where appropriate and the work area is cleaned before the engineer leaves.

Your Fixed Price Includes the Work Identified During Your Online Quote

Every property is different.

Some installations require additional work such as relocating the boiler, extending the flue, upgrading gas pipework or altering heating pipework.

Because BoxHeat asks detailed questions during the online quotation, these requirements are normally identified before you book. If they're needed based on the information you provide, they're already included within your fixed installation price.

There are no hidden extras for work that has already been identified during your quote.

Photo Verification Before Installation

Before installation, we'll ask you to upload photographs of your existing boiler, pipework and installation location.

This allows our technical team to confirm that everything matches the information provided during your online quote.

If the photographs show something that couldn't reasonably have been identified from the questionnaire, we'll contact you before installation to discuss any changes. No additional work is carried out without your agreement.

What's Not Included?

Standard boiler installations don't include:

  • Asbestos removal.
  • Scaffolding or specialist access equipment.
  • Structural building work.
  • Electrical work unrelated to the boiler installation.
  • Plumbing work unrelated to the boiler installation.
  • Additional work required because the installation differs from the information supplied during the online quote.
