Annan doesn’t often make national headlines. But right now, it’s sitting at the centre of one of the most significant infrastructure proposals in Scotland – and possibly the UK. In October 2026, the key distinction is between a proposed campus and an operating one. Base your autumn move on the home and commute available today, and check the planning register before relying on future jobs or infrastructure.
In September 2026, CXTech Limited submitted Planning Permission in Principle for a £16.5bn data centre campus on the former Chapelcross nuclear site, just outside the town. The plans include up to 750 construction jobs and around 540 permanent operational roles.
For anyone buying, selling or owning property in DG12, this is worth paying close attention to.
What’s actually been proposed at Chapelcross?
The former Chapelcross nuclear power station – a familiar landmark on Annan’s skyline for decades – has been earmarked as the location for a hyperscale data centre campus by CXTech Limited.
The application, submitted in September 2026, seeks Planning Permission in Principle. That means it’s the first formal step in a longer process, not a done deal.
No planning decision has been made. Scotland’s planning policy and environmental assessment requirements for large data centres are relevant to how the proposal will be assessed; the application should not be treated as permission to build.
What we can say is that the scale of the proposal – £16.5bn of investment, hundreds of jobs – is significant by any measure.
Why this matters for the Annan property market
Large-scale employment investment doesn’t just create jobs. It creates demand – for housing, for schools, for services, and for the kind of community infrastructure that makes a town more attractive to live in.
History gives us useful context here. When comparable towns have attracted major employer anchors – whether manufacturing plants, logistics hubs or tech campuses – local house prices have typically responded, often ahead of the facility even opening.
Dumfries and Galloway average house prices stood at £169,511 in July 2026, according to the UK House Price Index. That’s up 4.6% year-on-year – a meaningful rise for a region that has historically seen more modest growth than Scotland’s central belt.
If the Chapelcross proposals progress, demand in Annan could change. The scale, timing and location of any housing impact would depend on delivery, recruitment and workers’ housing choices.
Which Annan neighbourhoods could feel demand pressure first?
Not every street in Annan will be equally affected. Based on proximity to the Chapelcross site, access to amenities and existing buyer interest, a few areas stand out.
Silverwalk and Keswick Place
These established residential streets offer the kind of family homes that incoming workers with permanent roles tend to prioritise. Good access to local schools and the town centre makes them a natural first port of call for buyers relocating from outside the area.
Windermere Road
Windermere Road sits in a part of Annan that has quietly attracted steady buyer interest. Its mix of property types gives it broad appeal – from first-time buyers to those trading up. An influx of skilled workers looking to put down roots could sharpen competition here quickly.
The Carlisle Road corridor
The Carlisle Road corridor offers good connectivity – important for workers who may be commuting or who have partners working elsewhere in the region. Properties here tend to offer solid value relative to the wider DG12 market, which makes them attractive to buyers watching their budget carefully.
What sellers in Annan should know right now
If you’re thinking about selling in Annan, the timing of this news matters.
Buyer interest tends to follow major employment announcements, sometimes well before the first brick is laid. Searches for property in areas linked to large infrastructure projects often spike at the planning stage – not the completion stage.
Scotland’s ‘offers over’ pricing system means that well-presented homes in the right areas can attract competitive closing dates when demand rises. A Home Report is required for most residential properties marketed for sale in Scotland, with specified exemptions, so having yours in order ahead of listing is essential.
Getting an accurate, up-to-date valuation now means you’ll know exactly where you stand – and you can make a confident decision about whether to act.
What buyers in DG12 should consider
If you’re looking to buy in Annan, it’s worth thinking about what a project of this scale could mean for your long-term investment.
A few things to keep in mind:
- The planning process is at an early stage. Nothing is confirmed yet, and timelines for decisions can shift.
- Scottish planning policy and environmental assessment requirements for large data centres are relevant to the application and may affect its assessment.
- That said, even the proposal itself has already raised Annan’s profile. Interest from buyers outside the area is a natural consequence of that kind of attention.
- If you’re buying to live in Annan, the fundamentals – affordability relative to the central belt, community feel, proximity to the Solway Coast – remain strong regardless of the planning outcome.
A note on what we don’t yet know
It’s worth being honest about the limits of what can be said at this stage.
Planning permission in principle is the start of a process, not the end of one. Environmental assessment, policy requirements and the council’s decision remain important. Timelines for construction and operational phases, if the project proceeds, have not been confirmed.
What’s clear is that Annan is being talked about in a way it hasn’t been for a long time – and that, in itself, has a way of shifting buyer and seller behaviour.
