Open Handbook - Social cost-rent: a model for Community Buildings - DRAFT

A draft briefing note for organisations that own, or want to own, a building for community use: work in progress.

29 October 2026

In brief

Social cost-rent is a simple way to run a community-owned building. The building carries no debt and pays no dividends. It is let to organisations that serve their local community, and they pay what it costs to run and look after the building, and nothing more. Charges are set by published formulas, the books are open, and any surplus is returned to tenants or reinvested in the building.

This note sets out the model so that others can use it. It is free to adopt and adapt.

A note on the name: “social rent” has a specific meaning in housing. “Social cost-rent” is used here for workspace and community buildings, to make clear that rent is set by cost, not by the market.

Who it is for

The principles

  1. No debt and no dividends. The building is paid for up front, so tenants never pay for a loan or an investor’s return.

  2. Charges are set by published formulas. They change only when costs change.

  3. Shared costs are charged at cost. Tenants pay their own utilities and cleaning directly. Shared costs, such as insurance, maintenance and administration, go through a service charge that is estimated in advance, reconciled every year, and any underspend returned.

  4. The reserve is capped. Typically six months of running costs, raised up front and kept topped up. Anything above the cap comes back through lower rent.

  5. The repair fund is ring-fenced. Contributions follow a costed lifecycle plan for the building and stop growing once the plan is funded.

  6. Open books. Budget, actual spend, reserve and repair fund balances are published every year.

  7. Surplus goes back. Any surplus is returned to tenants through lower rent the following year, or reinvested in the building. Ideally, tenants decide which as members.*

  8. Space for the wider community. Ideally one space or floor is given rent-free to a local community organisation.

  9. No reliance on voluntary labour. The work of running the building is paid for, either through the service charge or through tenants’ own overheads.

  10. An asset lock. The building can never be sold for private gain.

* Ideally, the owning organisation’s governance allows open membership, so that tenants can become members and vote on how any surplus is used. Whether this is possible depends on the legal structure and governing documents.

How costs are charged

To keep things simple, tenants take on as much as possible directly, and only shared costs go through the owner. Tenants pay three things:

Service charge per m² per month = estimated shared costs ÷ (lettable m² × 12)

Rent per m² per month = (repair fund + reserve top-up) ÷ (lettable m² × 12)

An illustrative example

A building with 500 m² of lettable space:

Item

Per year

Per m² per month

Buildings insurance

£8,000

Communal areas (lighting, heating, cleaning)

Shared maintenance and safety checks

£15,000

Administration (accountancy, financial admin, legal)

£15,000

Service charge

£45,000

£7.50

Rent

£15,000

£2.50

Service charge and rent

Six-month reserve, raised up front

£22,500

Tenants also pay their own utilities and cleaning directly, so what each pays depends on how it uses its space.

Keeping costs fair

Running costs, and administration in particular, can vary a lot from one owner to another, especially where an owner manages several buildings. These safeguards stop tenants being overcharged:

Setting it up: step by step

  1. Agree the purpose and who the building is for. Write down the eligibility criteria for tenants, such as charities, co-operatives, social enterprises and community groups delivering local services.

  2. Choose a legal structure with an asset lock. For example, a community interest company, a charity (or a SCIO in Scotland) or a community benefit society. Take advice on which fits.

  3. Cost the building properly. Collect actual or estimated running costs, get a planned maintenance quote that includes reactive repairs, and commission a costed lifecycle plan for major replacements.

  4. Calculate the service charge and rent using the formulas above, and check them against the safeguards in Keeping costs fair.

  5. Take VAT and rates advice early. If rent carries VAT, tenants who cannot reclaim it pay about 20% more. Many tenants may qualify for charitable or small business rates relief.

  6. Raise the money. The ask has three parts: buying the building or clearing any debt on it, the opening reserve and, ideally, an endowment to start the repair fund.

  7. Write it into the governing documents and leases. The rent formula, tenants’ membership and voting rights where the structure allows it*, the reserve cap, service charge reconciliation and the repair fund all need a legal basis.

  8. Let the space openly. Use published criteria and a light-touch community benefit agreement with each tenant, setting out what they will offer the local community.

  9. Agree who does the work. Set out in writing who handles lettings, contractors, the service charge reconciliation and publishing the accounts, and what happens if whoever does it moves on.

  10. Publish everything. The formula, the budget, the accounts and the balances, every year.

The annual cycle

When

What happens

Before the year starts

Budget shared with tenants; service charge and rent set by the formulas and published

During the year

Building managed; monthly accounts kept; repairs paid from the service charge or repair fund

After the year ends

Service charge reconciled and any underspend returned; accounts published

At the annual review

Any surplus returned or reinvested, decided by member vote where tenants are members*; lifecycle plan and reserve reviewed

Every five years

Condition survey and full update of the lifecycle plan

Where it has been done

Cost rent is also standard practice in housing co-operatives, where members set rents to cover costs.
