Boiler Installation & Replacement – London

Professional boiler installation and replacement across North London and Greater London.

First Action Building Services provides professional boiler installation and replacement services for homeowners, landlords, letting agents and commercial clients throughout London.

As a Gas Safe registered contractor with 30 years of experience, we can assess your heating and hot-water requirements and recommend a suitable boiler and heating solution for your property.

New Boiler Installation & Replacement

Whether you are replacing an existing boiler or installing a new heating system, choosing the correct boiler is important for reliable heating, hot water and efficient operation.

We can assess your property, existing heating system and hot-water requirements before recommending suitable options.

If your existing boiler is becoming unreliable, inefficient or increasingly expensive to repair, replacing it may be worth considering.

We can inspect your existing boiler and heating system and discuss the available options before recommending a replacement.

A boiler does not automatically need replacing simply because it is old. We will consider its condition, reliability, performance, repair costs and the heating and hot-water requirements of your property before advising you.

Our boiler installation service can include:

  • Removal of the existing boiler where required
  • Installation of the new boiler
  • Appropriate heating controls
  • System preparation and flushing where required
  • Chemical inhibitor
  • Testing and commissioning
  • Gas safety checks
  • Appropriate certification and documentation
  • Advice on operating your new boiler

Choosing the Right Boiler

Every property has different heating and hot-water requirements.

We can assess your existing system and recommend a suitable boiler based on factors including:

  • Size and type of property
  • Number of bathrooms
  • Hot-water demand
  • Existing heating system
  • Available space
  • Heating requirements
  • Budget

We can discuss suitable boiler manufacturers and models with you and explain the available options before providing a quotation.

The correct boiler output and system design are important, so we recommend the boiler based on the requirements of the property rather than promoting one particular manufacturer.

Combination boilers, commonly known as combi boilers, provide heating and hot water without requiring a separate hot-water cylinder.

A combi boiler can be a suitable solution for many houses and flats, although the suitability and correct boiler output will depend on the property, incoming water supply and hot-water demand.

We can assess your requirements and advise whether a combi boiler is appropriate for your property.

Not every property is best suited to a combi boiler.

For properties with greater hot-water requirements or existing stored hot-water systems, a system boiler or regular boiler may be more appropriate.

First Action Building Services can assess the existing installation and discuss the most appropriate boiler and heating-system options.

Heating Controls, Testing & Commissioning

Modern heating controls can provide greater control over when and how your property is heated.

Depending on the heating system, we can install and configure appropriate heating controls as part of a new boiler installation or heating-system upgrade.

Our experience also includes S-Plan and Y-Plan heating systems and associated boiler wiring and controls.

Correct testing and commissioning are important parts of a professional boiler installation.

The heating system will be appropriately prepared, tested and commissioned in accordance with the applicable requirements and the boiler manufacturer's instructions.

Where required, the heating system will be cleaned and treated with suitable inhibitor.

The boiler, heating system and controls will then be checked to ensure they are operating correctly.

Building Regulations & Boiler Certification

New and replacement boiler installations are subject to applicable Building Regulations requirements.

Following the installation and commissioning, First Action Building Services will provide the appropriate documentation and relevant Building Regulations compliance documentation where applicable.

Full Central Heating Installation

In addition to boiler replacement, First Action Building Services provides full central heating installations.

Depending on the property and requirements, this can include:

  • Boiler
  • Radiators
  • Heating pipework
  • Heating controls
  • System configuration
  • Testing and commissioning
