Installing boilers and heating systems

Installing boilers and heating systems

If you want to install a new boiler in your home, you do not need to seek planning permission to do so. In the vast majority of cases, boiler installation is classed as permitted development. However, if you live in a listed building, it is recommended that you contact your Local Planning Authority for guidance. Please note that building regulations apply to boiler installation.

Planning permission

Boiler installation is considered to be permitted development and therefore, you do not need to apply for planning permission. However, there are limitations:

  1. External flues must not exceed the highest point of a roof by one metre or more.
  2. Listed buildings and property located in conservation areas may be subject to listed building consent and planning permission.
  3. Any external flue installed on to a property located in a conservation area must not be on the front of a property or any part of the property that fronts a highway.
  4. Any outside building that will form part of your boiler and heating system will have to follow the planning permission limitations of outbuildings and extensions.


Building regulations

If you have an existing boiler and heating system that simply needs to be replaced or modernised, it may not be necessary to apply for Building Regulation approval, and where it is necessary, you may not have to apply prior to carrying out any work. For brand new installations and heating system overhauls, however, Building Regulations approval will be needed.

For emergency works, there is no restriction on carrying out works without Building Regulations approval. Although, if work is not carried out by a professional, it is recommended that Building Control is notified immediately to assess the repairs are satisfactory. Companies such as Ideal Cleaning, often provide services for boiler outages, maintenance and PPM Works. Hiring one of these companies for your building would be wise in order to regulate boiler checks and maintenance, especially for buildings used as offices and social housing.

New boiler and heating system installs should be carried out as though work is being carried out on a new property. This means that energy efficiency requirements must be met.

Boiler replacement

In the case of a boiler replacement, Building Regulations require that certain standards are met to ensure health and safety and energy efficiency ratings are met. These standards are met by:

  1. Hiring an installer for gas boilers who is registered as Gas Safe from 1st April 2009.
  2. Hiring an installer for oil-fired boilers who is registered under the Competent Persons Scheme.
  3. Hiring an installer for solid fuel fired boilers who is registered under the Competent Persons Scheme.

Whatever the type of boiler installation, the installer must follow the guidelines set out in Approved Document J. This document outlines air supplies, hearths, flue linings and chimney labelling.

Efficiency ratings

Gas boilers must have an energy efficiency rating of 86% and oil-fired boilers must have an energy efficiency rating of 85%.

Responsibility of work

Responsibility for the safety and smooth operation of a boiler and heating system falls to the person who last worked on the system. In all circumstances, a certificate should be produced which clearly shows that all necessary checks have been carried out.
