Tritax Big Box Enters Development Management Agreement for Second Data Centre Scheme in Chelmsford

The company says it has now secured its first data centre development opportunities amounting to over 250MW, with a wider pipeline of c.1-gigawatt of further opportunities. Chelmsford is the second scheme in that push, so this is more than a one-off experiment.

For shareholders, the attraction is obvious. If Tritax can turn land, power access and development expertise into fully let data centres, it could open up a new source of growth beyond traditional sheds.

That said, data centre development is not passive property investing. It is more complex, more technical and more capital intensive, at least in practical terms, than buying an already-let warehouse. So while the upside may be better, the risk profile is not the same.

Tritax Big Box development fees explained – what the manager gets paid and when

The payment structure here is worth reading carefully because it tells you how value is split between shareholders and the manager.

• c.£3.3 million is payable for project assembly services already provided on the Chelmsford scheme.
• Up to 5% of the development cost is payable as a development management fee, but only if planning consent is received.
• 17.5% of total development profits is payable as a profit share, but only if the data centre is fully delivered, practically completed and let.

There is also some detail behind that 5% fee. According to the notes, 3.5% is paid in quarterly instalments after satisfactory planning permission is granted, and 1.5% is payable following the later of planning consent or exchange of an acceptable pre-letting agreement.

The profit share is calculated using the fair value of the asset base at completion, as confirmed by an independent valuer, less all associated costs. That matters because it ties the bigger payout to actual value creation, rather than simply spending money on a project.

My view on this is fairly balanced. On the positive side, the manager only earns the really meaningful upside if the scheme gets built and let. On the less positive side, a 17.5% profit share is material, so investors should expect strong returns if they are handing over that slice of the upside.

Targeted 10-11% yield on cost at Chelmsford – attractive on paper, but still only a target

Tritax says the targeted yield on cost for the scheme is 10-11%, and that this figure already includes the payments to Tritax Management. Yield on cost is basically the return the company expects to generate relative to what it costs to develop the asset.

That headline looks encouraging. If achieved, it suggests Chelmsford could be a profitable project even after management fees and profit share.

But it is still a target, not a delivered outcome. The RNS does not disclose the total development cost, the valuation on completion, the expected rent, the identity of any tenant, or the timetable for planning and construction. Those are big missing pieces, so investors should not treat 10-11% as money in the bank.

Related party transaction at Tritax Big Box – should investors worry?

Because Tritax Management is a related party, this deal falls under the UK Listing Rules. A related party transaction simply means the company is doing business with a connected party rather than a completely independent third party.

That always deserves a bit of scrutiny, because conflicts of interest can arise when a manager is effectively negotiating with the company it manages. The reassuring part here is that the board says the development management fee and profit share arrangement are fair and reasonable for shareholders, and Jefferies International Limited advised the directors in its role as sponsor.

That does not remove all concern, but it does strengthen governance around the arrangement. For me, this is not a red flag announcement, but it is a reminder that investors in externally managed property vehicles should pay attention to fee structures.

What Tritax Big Box did not disclose in this Chelmsford RNS

There is enough here to understand the structure, but not enough to build a full financial model. Several important details were not disclosed:

• Total development cost – not disclosed
• Expected construction timetable – not disclosed
• Planning status beyond the intention to pursue planning – not disclosed
• Tenant or pre-let agreement – not disclosed
• Funding structure – not disclosed
• Projected rental income or completed asset valuation – not disclosed

That means this RNS is more about process and strategic direction than near-term earnings. It tells you the project is progressing, but not yet what the final economics will look like in full.

My take on Tritax Big Box’s second data centre scheme in Chelmsford

Overall, I’d call this a positive strategic update with a few caveats. Positive, because Tritax is building momentum in data centres and appears to be applying the same framework used at Manor Farm, Heathrow to a second 125MW project.

The targeted 10-11% yield on cost is attractive, and the fact that half of the manager’s profit share must go into company shares, with a 12-month lock-up, gives at least some alignment with shareholders. That is better than a pure cash extraction model.

The caveat is simple: execution now matters more than ambition. Chelmsford still needs planning, construction, power delivery and leasing to fall into place before shareholders see the benefit.

So the big takeaway is this: Tritax Big Box is steadily evolving from being just a logistics landlord into something broader, with data centres now a serious part of the story. If that strategy works, it could be very valuable. If it stumbles, investors will quickly start asking whether the extra complexity was worth it.
