Securing affordable workspace through a planning obligation

Affordable workspace london obligations look simple in a heads of terms and turn out to be the most argued-over clause in the agreement. A borough asks for a proportion of the commercial floorspace at a discount to market rent, for a defined period, managed by a workspace provider it accepts. Each of those four elements can be drafted to work or drafted to collapse, and the drafting usually happens late, under pressure, after the viability position is already fixed.

The policy basis sits in the London Plan's economy policies and in borough local plans, which set the circumstances where affordable workspace is sought and sometimes the discount itself.

Why boroughs ask for it

Rents in parts of London price out the small businesses, studios and charities that boroughs want to keep. Affordable workspace is the planning answer: a cross-subsidy inside a commercial scheme, secured by obligation, aimed at a tenant profile the open market would not serve.

That purpose shapes how the clause should read. If the drafting allows the space to be let to anyone who will pay the discounted rent, the borough has bought nothing it could not have got anyway. If it is drafted so tightly that no operator will take it, the space sits empty and the obligation delivers nothing. The useful middle ground defines the tenant profile by sector or business size, not by naming individual occupiers.

How the discount is expressed

Discounts are usually expressed as a percentage of open market rent for comparable space in the locality, and that definition is where the arguments start. Comparable to what, assessed by whom, and at what date.

The service charge point deserves its own sentence. A rent at a steep discount with an uncapped service charge on a new build can cost a small tenant more than market space in an older building. Boroughs increasingly ask for the discount to be expressed on a total occupancy cost basis, and that is the harder version to deliver, so price it before you agree it.

Fit-out standard and the traps in it

A discounted rent on a shell is not workspace. Someone has to install floors, services, partitions, lighting, a kitchen and accessible facilities, and the cost of that fit-out is the hidden half of the obligation.

Three positions exist. The developer delivers fitted space ready to occupy, which is the most expensive and the most likely to be used. The developer delivers to a defined intermediate standard and the operator fits out, which is the common compromise and needs the standard written out in a schedule. Or the developer delivers shell and core, which almost always means the space stands empty while the operator seeks grant funding.

Write the standard as a specification, not as an adjective. Floor finish, ceiling condition, mechanical ventilation rate, electrical capacity per workstation, data provision, number and type of sanitary facilities, and whether a kitchen and a lift lobby are included. A clause saying "to a standard reasonably fit for occupation" will be litigated by correspondence for two years.

Selecting and binding an operator

Most affordable workspace is managed by a specialist provider rather than by the developer. The obligation needs to say how that provider is chosen, what happens if none is found, and what the provider is committed to.

A workable structure runs through four steps:

1. The developer markets the opportunity to workspace providers on terms set out in the agreement.
2. The borough approves the selected provider against stated criteria, within a defined period.
3. The provider enters a lease at the discounted rent for the discount period, with a management plan approved alongside it.
4. A fallback applies if no provider is appointed, usually direct letting on the same discounted terms with monitoring by the borough.

Step four is the one people leave out, and the one that decides what happens in the real world. Without a fallback, an unlet affordable workspace unit becomes a standing dispute with no mechanism to resolve it.

Length of the discount period

Periods vary by borough and by scheme. What matters more than the headline figure is what happens at the end of it, and whether the clock starts on practical completion or on first letting.

Start the period on first occupation of the affordable workspace, not on practical completion of the building. Otherwise a slow letting campaign eats the discount period at the borough's expense. At the end, say explicitly whether the space reverts to market rent, whether a renewal is offered to the sitting tenant, and whether the obligation is discharged automatically or requires written confirmation. Agreements that go silent at this point produce a dispute in year eleven, when nobody involved in the negotiation is still at either organisation. Our note on industrial land and no net loss in a strategic location deals with a related protection applied to a different floorspace type.

Valuation and viability consequences

An affordable workspace obligation reduces the rental income from part of the commercial floorspace, which reduces the capital value of that element, which feeds directly into the residual land value in a viability appraisal.

That is a legitimate input, and the Planning Practice Guidance on viability, read with the relevant professional guidance, sets out how such obligations are reflected in an appraisal. Two disciplines matter. State the obligation's assumptions explicitly in the appraisal rather than burying them in a blended rent, because an assessor who cannot see them will substitute their own. And deal with the fit-out cost as a cost line, not as a rent adjustment, since the two have different timing and different risk.

Where an affordable workspace requirement is being used to argue down affordable housing, expect scrutiny. Boroughs read that argument as a choice between two policy objectives rather than as a technical finding, and they will test which floorspace assumptions are driving it. The same tension appears in schemes within opportunity areas, where multiple policy asks land on the same appraisal.

Drafting that works in practice

Short clause, tight definitions, named mechanisms. The agreement should answer all of the following without needing a surrounding document. Which floorspace, measured how and shown on which plan. What rent, defined how and reviewed when. What fit-out standard, and in which schedule it is specified. Which tenant profile. Who manages the space and how they are chosen. How long the discount runs. What happens at the end. And what the borough can do if the space is not delivered.

Then check one thing before signing. Does the obligation bind successors in title to the commercial element, including a purchaser of the freehold or a long leaseholder of the commercial unit. An obligation binding the developer alone is worth very little once the building is sold. The same question applies to protecting a public house through an obligation, where the asset can change hands several times.
