Guernsey has capped runway rehabilitation at £24m, but other “pipeline projects” tied to Alderney airport may require fresh approvals—and could push total costs higher.
The States has capped spending for Alderney airport runway rehabilitation at up to £24m, but the wider capital plan includes other works that may not fit within that limit.
The decision was made by granting delegated authority to Policy & Resources to fund the runway rehabilitation, described as necessary work to restore the runway.. At the same time, Alderney airport sits inside a broader list of “major capital portfolio” projects, including so-called “pipeline projects” such as a new airport control tower, terminal building, and fire station.
That distinction matters because it changes how the public is likely to understand the headline figure.. While the runway cap is fixed for now, Guernsey Ports says any major work on the terminal, fire station, control tower, and related buildings would need to return to the States of Guernsey for approval, including confirmation of funding.. In other words, the £24m figure is not a total bill for Alderney airport in coming years—it is a cap for one specific rehabilitation scope.
The earlier redevelopment plan offers context for why the spending envelope is being drawn so tightly.. A terminal and fire station had been part of a broader scheme when costs were previously estimated at about £37m.. That wider plan was rejected, and the States then moved toward a narrower approach—approving a £24m cap focused solely on runway rehabilitation.
A human consequence of this split is that residents planning around public finances may find “what’s approved” and “what’s still needed” harder to keep in sync.. One part of the airport receives a defined funding route, while other essential assets sit in a portfolio pipeline that can demand additional approvals later.. Former States Trading Supervisory Board president Peter Roffey argued in a column that it remains uncertain whether taxpayers will see spending stay below higher expectations, framing the risk as a potential gap between the capped project and the full set of airport requirements.
Guernsey Ports also says practical constraints are already shaping the timeline. With the control tower, temporary measures are in place to keep it operating. Temporary repairs are expected to keep it running for a couple more years, but a full replacement is ultimately necessary.
A portfolio report described the control tower as having reached the end of its operational life.. Continued use was assessed as sustainable for 18–24 months from October 2024, provided reinforcement work continues to keep the structure safe and secure.. The approach aims to extend the tower’s use by another two to three years while options are explored for a safe and compliant long-term solution.
That longer-term solution is not yet costed. Ports says a range of options is being explored, and it is likely the work will need to go before the States of Deliberation for approval. At present, the work remains at an early stage, with no costed proposals available.
Beyond the tower, the States’ description of the major projects portfolio report signals why decisions may unfold in a more staged way.. The new approach is meant to plan, prioritise, and manage major projects with more emphasis on early-stage planning—avoiding commitments before costs and constraints are clearer.. It also links major project decisions to the medium-term financial plan, which—according to the States—can better account for wider financial pressures.
Looking ahead, the immediate implication for Alderney airport is that budgeting may be handled in layers: runway rehabilitation funded under the delegated authority now, and other major works progressing through the portfolio process and returning to lawmakers for approval when funding and proposals are ready.. For taxpayers and planners, the key question may be less about whether the £24m runway cap is real, and more about how quickly and expansively the later, separate “pipeline” items move from planning to funded delivery.
