On-Site London Ltd provide Airside Cleared M&E and construction operatives and staff in full compliance with the Heathrow Airport Ltd (HAL) IR Policy.

Since 2012, On-Site London has been an authorised airside signatory, providing M&E and Construction tradespersons on contracts of employment with the terms and conditions that are expected of any contracting employer. We pride ourselves on ensuring quality operatives are engaged in the right manner, and with respect and fairness that any worker should expect.

Our clients are synonymous with high quality installations, on Heathrow Airport’s highest profile and largest projects to date.

We work hard to maintain a positive working relationship with the end client, HAL, to ensure we stay in line with their policies and that we provide the service levels they expect of any provider on their projects.

We recognise the need for productive industrial relations with the trades unions, and endeavour to maintain regular contact that allows us to ensure we employ our workforce properly, whilst minimalising any potential disruption due to IR issues.


On-Site are members of the JIB Industrial Information Service, allowing us to ensure that ECS cards are up to date, and grades are relevant and correct. We also have access to the CSCS database to verify trades cards and the qualifications of other tradespeople.

This allows us to ensure that workers supplied by us are appropriately qualified and competently trained to carry out the tasks they are assigned to do.

Everyone that wishes to work for us at Heathrow Airport undergoes a strict vetting process in order to get them cleared to work Airside. This includes obtaining written references to cover the past 5 years, right to work in the UK, Criminal Record check and GSAT training.

We employ every worker.

Every worker is engaged on a Contract of Employment, on terms and conditions equivalent to the relevant National Working Rule Agreement, as prescribed by the HAL IR Policy. Benefits provisions set out in those agreements are adhered to through participation in the industry benefits scheme.

We pride ourselves on operating in a compliant manner, offering a high standard of customer service and in a fair manner as an employer. You can be sure that you can rely on On-Site London (Ltd) to support your business.
