NHS Rent Reimbursement and Lease-Backed Primary Care Premises Finance in 2026

Almost every question about medical centre finance eventually comes back to one thing: how the rent gets paid. In primary care, most of that rent is reimbursed by the NHS, and that single fact is why a GP surgery or a purpose-built medical centre borrows on finer terms than an ordinary shop, office or warehouse of the same size. Lenders are not really lending against the bricks. They are lending against a rent cheque that the NHS keeps paying. This guide from Medical Centre Property Finance explains how NHS rent reimbursement actually works, who assesses the rent, how often it is reviewed, and exactly how lenders turn that government-backed income into keener margins, higher leverage, lower cover requirements and a genuine appetite for interest-only.

How NHS rent reimbursement works

A GP practice does not usually pay its premises cost out of its own pocket and hope. Where the premises are used to deliver NHS primary care under a General Medical Services (GMS) or Personal Medical Services (PMS) contract, the local Integrated Care Board (ICB) reimburses the cost of occupying the building. The ICB is the payer that plans and funds most health services in an area, and it replaced the older clinical commissioning groups. For an owner-occupier practice that owns its surgery, the reimbursement comes as notional rent. For a practice that leases its building, the reimbursement covers the rent.

This is the mechanism that makes primary care property different. The occupying practice is a small business, but the money that services the premises comes, directly or indirectly, from the NHS. That is why a specialist reads a medical centre as an income-led asset with a government-backed tenant behind it, rather than as an ordinary commercial let that lives or dies on one company’s trading.

Notional rent, cost rent and leasehold reimbursement

There are three reimbursement bases, and it is worth being precise about them because lenders underwrite each one slightly differently.

Notional rent is the reimbursement a practice receives when the GP partners own the freehold of the surgery they occupy. The NHS pays them as if they were renting the building at its open market level, so the partners collect an income stream on their own property. This is the most common basis for an owner-occupier.

Cost rent is an older basis that linked reimbursement to the actual cost of building or substantially modifying a surgery, rather than to open market rent. Many practices that were once on cost rent have since moved across to a notional rent basis, but the term still appears on legacy premises.

Leasehold reimbursement applies where a practice rents its building from a third party, whether a private landlord, an investor-let structure, or a listed estate owner. Here the NHS reimburses the Current Market Rent or the actual rent set out in the lease, whichever is lower. That “whichever is lower” test matters, because it caps how far a landlord can push rent above the assessed market figure and still expect the NHS to cover it.

The District Valuer and Current Market Rent

The number that anchors all of this is Current Market Rent (CMR). It is the rent judged reasonable for the premises, and for many years it was assessed by the District Valuer Services (DVS), the specialist arm of the Valuation Office Agency. Since the 2024 rules, an approved chartered surveyor can also carry out the assessment, which has widened capacity and, in practice, sped some reviews up.

The assessment follows a defined basis rather than a negotiation. Current Market Rent is set by reference to a notional 15-year lease, with the tenant responsible for internal repair and the landlord responsible for external and structural repair and insurance. That is close to a full repairing and insuring (FRI) footing on the parts that matter to a valuer, and it gives lenders a consistent, independently assessed figure to work from. When a lender sizes a facility on a medical centre, the District Valuer’s assessment of CMR is the income they trust, because it is arrived at independently and it drives what the NHS will actually pay.

The three-yearly review and the Premises Costs Directions 2024

Reimbursed rent is not fixed forever. It is reviewed on a cycle, typically every three years, and reassessed against open market evidence at each review. The current rules governing all of this in England are the Premises Costs Directions 2024, which set out how premises costs are reimbursed and which introduced the option for approved chartered surveyors to assess notional rent alongside the District Valuer.

For a lender, the three-yearly review is a feature, not a risk. It means the income is periodically marked back toward the market, so a long facility is not stuck on a rent that has drifted out of line. It also sets up the reversion story covered further down, because rents have grown slowly and many older surgeries sit below where a fresh review would put them.

Why lenders treat reimbursed income as government-backed

Here is the heart of the angle. When the rent behind a building is reimbursed by the NHS, the covenant is effectively a government one. The occupying practice could be small, but the cash flow that services the debt traces back to public funding, and public funding does not default in the way a private tenant can. Lenders describe this as government-backed income, and they treat it as low-default and highly predictable.

The scale of that reliance is visible in the listed market, which is the clearest public window on primary care income. As market context, one large listed primary care estate reported that around 76% of its rent roll was funded directly or indirectly by the NHS or the HSE at the end of 2025 (Primary Health Properties, 2025). Estate owners such as Assura and Primary Health Properties are landlords, not lenders, but their reporting shows why a funder views a well-let surgery as one of the safest income streams in commercial property. That security is also why prime primary care yields held at around 4.5% in 2025, the keenest yielding healthcare sub-sector (Savills, 2025), while UK healthcare real estate investment set a record at over £12 billion, with primary care about 16% of activity (Savills, 2025).

How reimbursement improves pricing, leverage and interest-only

Government-backed income does not just make lenders comfortable in the abstract. It shows up in four concrete places on a term sheet, and each one is finer than an ordinary commercial property of similar size would get. All of these figures are indicative market commentary.

Finer margins. Senior term debt on a well-let, NHS-reimbursed centre sits at around 1.75% to 3.25% over the base or reference rate, broadly 5.5% to 7.0% all-in against a Bank of England base rate held at 3.75% since December 2025. Modern, purpose-built centres on long leases sit at the lower end of that band.

Higher leverage. Loan to value (LTV) on acquisition and term facilities runs at around 65% to 80%, and the upper end is reserved for exactly this profile: modern, purpose-built, long-let NHS-reimbursed premises. Older surgeries or shorter unexpired leases are typically capped nearer 60% to 70%. Owner-occupier GP partnerships can often borrow toward the top of the range where notional rent supports the debt service.

Lower cover requirements. Debt service cover (DSC), which is net rental income divided by annual debt service, is typically set at around 1.25x to 1.5x on secure reimbursed rent. That is lower than a lender would demand on a trading business, precisely because the income is predictable. Lenders will also look at interest cover ratio (ICR) and debt yield to sense-check affordability, but the reimbursed flow does the heavy lifting.

Interest-only appetite. Because the income is long, secure and reimbursed, interest-only is common on primary care where it would be unusual on ordinary commercial property. Part-amortising structures come back in on shorter leases or weaker income.

The single biggest driver behind all four is the share of income that is reimbursed and the length of that income, measured on let centres as the weighted average unexpired lease term (WAULT). Long WAULT on a modern centre earns the best terms. The market prices the difference plainly: short-dated surgeries on older buildings have yielded around 75 basis points higher than new-build investments on 20-year-plus leases (Edison Group, 2026). Specialist healthcare and primary care lenders, challenger banks and high-street banks all compete hardest for the long-let, reimbursed end and turn cautious as leases shorten.

Rent review lag and reversion: risk and opportunity

The slow pace of primary care rent growth cuts both ways. Rents have grown on average below 2% a year over the past decade (Savills, 2025), which is slower than most commercial sectors. The consequence is reversion: many older surgeries are let below open market rent, so the passing rent sits under what a fresh assessment would produce.

For an owner or investor, that reversionary rent is an opportunity, because the next three-yearly review can capture some of the gap and lift income. For a lender, it is a reason for measured optimism rather than a number to bank in advance. A funder will usually underwrite the current reimbursed rent and treat any uplift on review as upside, not as committed cash flow. The review cycle keeps the income honest, but the timing lag means the gap closes gradually rather than in one step.

What reimbursement does not cover, and how lenders treat it

Not every pound of income on a medical centre is reimbursed, and lenders draw a sharp line here. NHS-reimbursed rent is the secure core. Non-reimbursed commercial income, such as an on-site pharmacy, private clinic space or other lettings, is treated far more cautiously and may be discounted or haircut when a lender sizes debt. That income depends on private trading, not on public funding, so it carries ordinary commercial risk.

The practical effect is that two centres with the same headline rent can borrow very differently. A surgery where nearly all the rent is reimbursed will attract keener pricing and higher leverage than one where a meaningful slice comes from a pharmacy tenant, even if the total looks identical on paper. This is also where building quality feeds in: Care Quality Commission (CQC) compliant, accessible, purpose-built premises support the secure income best, while dated or converted stock narrows appetite.

It is worth setting this against the wider estate picture. A large share of GP premises is old and undersized, government policy through the NHS 10-Year Plan, the Estates and Technology Transformation Fund and the wider Primary Care Infrastructure Fund is pushing new Neighbourhood Health Centres and modernisation, and private capital continues to enter through third-party developer models, sale and leaseback deals and the legacy LIFT (Local Improvement Finance Trust) framework. Development finance for new centres is sized on loan to cost and gross development value (GDV), while mezzanine finance and bridging finance fill specific gaps, but the anchor under all of it remains the same reimbursed rent.

Frequently asked questions

Why does NHS reimbursement make a GP surgery cheaper to finance? Because the rent that services the debt is reimbursed by the NHS through the local Integrated Care Board, lenders treat the income as government-backed and low-default. That predictability supports finer margins of around 5.5% to 7.0% all-in on senior term debt, higher LTV of up to around 80% on long-let centres, lower debt service cover of around 1.25x to 1.5x, and a real appetite for interest-only, all keener than ordinary commercial property of the same size would attract.

Who decides the rent, and how often does it change? The rent is assessed as Current Market Rent by the District Valuer Services or, since the Premises Costs Directions 2024, by an approved chartered surveyor. It is reviewed on a cycle, typically every three years, against open market evidence, and is assessed on a notional 15-year lease with the tenant responsible for internal repair and the landlord for external and structural repair.

Is income from a pharmacy or private clinic treated the same way? No. Only the NHS-reimbursed rent is treated as secure, government-backed income. Non-reimbursed commercial income such as pharmacy or private clinic rent carries ordinary trading risk, so lenders treat it more cautiously and may discount it when sizing a facility.
