NHS Property Services Billing Disputes: How GP Practices Can Challenge Inaccurate Service Charges

NHS Property Services (NHSPS) manages approximately 3,000 properties across England, housing a large proportion of NHS GP practices. For most practices in NHSPS buildings, the monthly service charge invoice is one of the largest fixed costs the practice carries. According to the BMA (2025), 54% of NHS Property Services tenants report that billing disputes directly threaten the financial sustainability of their practice.

The problem is structural. NHSPS service charge bills are built from apportionment models, internal overhead allocations, and cost recovery schedules that practices receive as a total figure. Most practices lack the specialist knowledge to verify whether the figure is accurate, what it is composed of, or where the errors are likely to sit. This information asymmetry is not accidental — it is a feature of how service charge billing works, and it systematically disadvantages tenants who do not challenge it.

54% of NHSPS tenants say billing disputes threaten practice sustainability (BMA, 2025). Common overcharges include: services not delivered, incorrect floor area apportionments, VAT applied incorrectly, and management fee percentages exceeding the lease terms. Practices have successfully recovered five-figure sums through formal dispute processes.

What Are the Most Common Types of NHSPS Billing Error?

Service charge errors in NHS Property Services accounts tend to cluster around five categories. Understanding these categories is the starting point for an effective challenge.

• Incorrect floor area apportionment — service charges are typically apportioned across tenants by floor area. If the floor area attributed to your practice in the apportionment schedule is wrong, you are being overcharged in proportion to that error. This requires comparing the apportionment schedule against a measured survey of the actual occupied area.
• Charges for services not delivered — practices are routinely billed for services that were not provided or were provided at a materially lower standard than contracted. Grounds maintenance, window cleaning, communal area cleaning, and lift maintenance are common categories where charges continue after services are suspended or reduced.
• VAT treatment errors — NHS GP practices are partially exempt from VAT. Service charges on healthcare premises are subject to specific VAT rules, and misapplication of VAT adds cost that the practice is not legally required to pay.
• Management fee overcharges — NHSPS management fees are capped as a percentage of qualifying expenditure under standard NHS lease terms. Where the fee percentage applied exceeds the contractual cap, the overcharge is directly recoverable.
• Capital vs revenue misclassification — capital expenditure recharged through the service account as a revenue item is recoverable if it exceeds what the lease permits.

What Documentation Do You Need to Challenge a Bill?

An effective challenge requires documentation that NHSPS is obliged to provide but does not routinely send with its invoices. Practices are entitled to request this information formally.

1. Certified service charge accounts — the full reconciled accounts for each service charge year, certified by the managing agent. These break down every cost line and show how the apportionment was calculated.
2. Apportionment schedule — the floor area schedule used to calculate your share of shared costs. Compare this against your actual occupied area from a measured survey.
3. Service delivery records — the documented record of services actually delivered against each charged line. Grounds maintenance visit logs, cleaning records, and contractor sign-off sheets.
4. Management fee calculation — the calculation showing how the management fee was derived, including the fee percentage and the qualifying expenditure base.
5. Copies of all contractor invoices — NHSPS must produce these on request. Spot-checking invoice totals against charged amounts is an efficient way to identify discrepancies.

What Is the Formal Dispute Process?

The first step is a written dispute notice to NHSPS identifying the specific charges you are challenging and the basis for the challenge. The letter should reference the relevant clause of your lease and request a response within 28 days. NHSPS has an internal dispute resolution process. If internal resolution fails, the matter can be referred to the First-tier Tribunal (Property Chamber) under Section 27A of the Landlord and Tenant Act 1985, which has jurisdiction to determine the reasonableness and payability of service charges.

Before escalating to tribunal, most practices achieve resolution through a formal letter before action supported by a specialist service charge surveyor's report. The existence of a professional report quantifying the overcharge changes the commercial calculation for NHSPS significantly. The practices that recover money are those that get specialist support early, document everything in writing, and do not accept verbal reassurances from account managers in place of formal written responses.

What Can You Realistically Recover?

The recoverable amount depends on the size of the practice, the duration of the overcharging, and the nature of the errors. Practices with three or more years of unreviewed service charge accounts — which describes most NHSPS tenants — frequently find five-figure overcharges on initial review. The largest recoveries come from floor area apportionment errors that have been compounding for multiple years, and from capital expenditure items incorrectly recharged through the service account.

Service charge review is not a one-time exercise. The errors that produced the first overcharge recur in subsequent years unless the underlying data is corrected. Practices that establish a routine annual review of their NHSPS accounts — comparing service charge reconciliations against their lease terms and requesting delivery records for charged services — systematically reduce the risk of accumulating future overcharges.
