Planning and development
Our vision for Glasgow Airport is to be Scotland’s preferred business and leisure airport by developing a strong and lasting route network and delivering an unrivalled customer experience. Our master plan, which was updated in 2011, sets out a clear strategy for future airport development aligned to this vision.
Glasgow Airport is an asset of strategic national importance, providing employment for more than 7,300 people across Scotland and generating nearly £200 million annually for the economy, more than any other airport in Scotland. As the airport grows, so too will the substantial contribution it makes to Scotland’s economic success.Not only does the master plan outline how the airport can grow to accommodate increased passenger demand up to 2040, it considers the benefits of a successful and growing airport that underpins both the local and wider Scottish economy.

Glasgow Airport Strategic Transport Appraisal Part 2 Executive Summary

Aerodrome Safeguarding is the process used to ensure that the operation and development of Glasgow Airport is not inhibited by new developments in its vicinity. In particular, the process contributes to the safe operation of aircraft during the approach and landing procedure, while taking-off, while flying in the airport’s vicinity, or while manoeuvring on the ground.
The process by which developments in the vicinity of the aerodrome are referred for consultation is set out in the Town and Country Planning (Scotland) Act 1997 (as amended) and Circular 2/2003: Town and Country Planning (Safeguarding Aerodromes, Technical Sites and Military Explosives Storage Areas) (Scotland) Direction 2003.
Developments which can impact on the operation and development of the airport include:
- Tall structures
- Developments that may provide habitat or feeding ground for birds
- Lighting schemes
- Wind turbines
Where issues are identified we will always seek to work with developers to mitigate and enable development to proceed. In the case of predicted impact of wind turbines on primary surveillance radar, we have an established radar mitigation process for developers to follow. Our Strategic Turbine Mitigation Scheme offers a scalable solution that meets the objectives of developers, planning authorities and aviation stakeholders through a pioneering deployment of leading edge smart technology backed by a number of processes, operational procedures and legal obligations on both the Airport and any benefitting developer to ensure that the safe and efficient operation of the airport is not impacted at any point in the wind farm’s lifetime.
The Airport Operators Association (AOA) has produced several advice notes providing useful information and guidance on safeguarding issues. These issues can be viewed here.
We would advise developers to consider safeguarding issues prior to submitting planning applications and are happy to provide pre-planning advice.
If you have any safeguarding enquiries, please contact our Safeguarding Manager on 07808115881.

AGS tax arrangements
AGS pays a range of taxes in the UK, including Corporation Tax, Employment Taxes, VAT, Insurance Premium Tax and Business Rates.
Our tax policy is to operate both within the letter and spirit of the UK’s tax laws at all times.
Approach to tax governance and risk management
AGS conducts its business through its three UK airport sites, with no overseas operations.
AGS operates a system of tax risk assessment and controls as a component of its overall risk management and internal control framework.
We manage risks to ensure compliance with legal requirements in a manner that ensures payment of the right amount of tax at the right time.
The ultimate responsibility for AGS´s tax strategy and compliance rests with the Board of Directors. The Chief Financial Officer maintains executive responsibility for tax matters and for fulfilling compliance requirements.
Attitude to tax planning and level of risk
AGS seeks to reduce the level of tax risk arising from its operations as far as is reasonably practicable by ensuring that reasonable care is applied in relation to all processes which could materially affect its compliance with its tax obligations.
As part of our business and commercial operations we seek to utilise available tax reliefs, incentives, and exemptions in line with both the intent and letter of tax legislation.
AGS does not undertake tax planning inconsistent with its commercial objectives.
The level of risk that AGS is willing to accept in relation to UK tax is consistent with its overall objective of achieving certainty in its tax affairs.
We will seek external tax advice where necessary to ensure the right amount of tax is determined in any complex circumstances.
Relationship with HMRC
AGS seeks to have a transparent, honest, and constructive relationship with HMRC.
Any inadvertent errors in submissions made to HMRC are fully disclosed as soon as reasonably practicable after they are identified.
