Are you up to date on the latest standards? BS 5410 Part 1 2019

The standard came into effect on 30th June 2019 and it sets a new scope, now solely for domestic applications with an output not exceeding 70kW and oil storage that does not exceed 3500 litres. The standard is to be applied to existing as well as new and replacement installations and calls for customers to be formally notified of any deficiencies found.

Non-domestic installations and installations at domestic premises in excess of 70kW should refer to BS 5410 Part 2 2018.

The BS 5410 Part 1 2019 also covers installations combusting liquid fuels for domestic heating and hot water purposes including kerosene, bio-liquids and kerosene/ bio-liquid blends such as OFTEC’s B30K. Below are some of key points of importance in the newly published standard:


  • Clarifies the responsibilities of those installing appliances and systems as well as those undertaking service and commissioning works


  • Clarifies what and how engineers are to advise domestic householders when problems are found or arise


  • Recommends the fitting of CO detector alarms, including for existing installations


  • Recommends HHIC guidance on condensate disposal pipework


  • Recommends that installers should only fit integrally bunded oil storage tanks which are designed to permanently vent the bund to atmosphere


  • Those oil tanks should have a minimum of 300mm clearance for visual inspection and 600mm for physical access


  • All oil storage tanks should have secondary containment and where they do not, they should be identified as either a potential or immediate risk as appropriate. The customer should be formally notified, and a warning sticker affixed


  • Oil supply lines should not contain plastic ancillary equipment such as filter bowls or deaerators


  • Where oil supply lines are inaccessible or hidden, preventing visual inspection, they should be pressure tested at least once every 5 years


  • The standard calls for service and commissioning engineers to have undergone manufacturer’s product type training before working on new technologies e.g. blue flame, two stage and modulating burners etc.


  • It also calls for all engineers to be registered with an approved oil registration scheme, such as OFTEC.


Due to such significant and detailed changes to this new industry standard, we strongly recommend that those involved in the manufacturing, specification, design, installation, service and commissioning of oil-fired equipment should obtain a copy and review it against the products, goods and services they offer without delay.

This is the standard against which we in our industry are all measured and judged in the event of civil action or claim against us. The standard can be obtained from the BSI shop, follow the direct link here:

As a consequence of the publication of this new standard, EOGB have reviewed and included additional information and updates regarding BS 5410 to its OFTEC oil training courses. Additionally, and in response to engineers’ requests, EOGB have taken the unprecedented step of writing a dedicated new vaporising training package – increasing the training time available for the OFTEC 101 & 102 (W/D) vaporising course to enable more details to be covered.

This will also be available as a specific standalone training and assessment package for engineers who want to be up to date and do the best job they can for themselves and their customers.
