The Council will keep S106 contribution costs under review to ensure they reflect current market conditions. In all cases, the most up‑to‑date calculations will be applied, depending on the type of infrastructure to be provided, either on‑site or through full or partial commuted sums (financial contributions).
The infrastructure types below use the latest available figures. These are generally updated on or around 1 April each year. The S106 Estimator also uses these figures.
Note: As of June 2026, a new version of the S106 estimator has been designed, updating and improving on the original version. This version is now available to download on the S106 Estimator page.
Detailed below are the updated costs for each type S106 contributions.
As set out in the Affordable Housing Policy and Developer Contributions Supplementary Planning Guidance, and the Affordable Housing Contributions arising from Student Accommodation Supplementary Planning Document, there may be circumstances where Nottingham City Council will accept commuted sums (financial contributions) in place of on‑site affordable housing. For student accommodation, this is generally the preferred approach.

The guidance sets out the methodology for calculating commuted sums, based on data published by the Land Registry. The figure is updated annually in April (or when new data becomes available).
For the 12‑month period to April 2026, the average price of a semi‑detached dwelling in Nottingham City was £228,844.29 (standard transactions only). A contribution equivalent to 25% of this figure (£57,211.07 per affordable dwelling) will be used as a starting point for negotiation.
Further explanation about the formulas used is set out in the SPDs (see links above). The S106 Estimator can be used to calculate indicative contributions for residential and commercial development.

As set out in the Provision of Open Space in New Residential and Commercial Development SPD (2026), there are instances where Nottingham City Council will accept commuted sums in lieu of onsite open space.
The current multiplier for off‑site contributions is £1,345.00 (updated May 2026). This is used to estimate the cost of providing new open space per person. Contributions are based on the expected number of occupants, as follows:
|
Type of Development |
Contributions based on |
|
Residential development (including Student) |
Where 10 or more dwellings (non-student) / bedspaces (student) then the contribution are based on dwelling/development size and the corresponding number of likely occupants. |
|
Commercial (uses typically but not exclusively found under Use Class E(g)) |
Likely number of employees, with discounts applied. |
Further detail on the calculation methodology is set out in the SPD. The S106 Estimator can be used to calculate indicative contributions for residential and commercial development.

As set out in the revised Education Contributions from Residential Development SPD (2026), contributions for school places are based on the relevant average regional costs published in the latest Department for Education school places scorecard, with a 10% uplift applied.
Current costs are:
-
£23,169 per primary pupil,
-
£31,867 per secondary and post‑16 pupil,
-
Plus, a 7.5% uplift for special educational needs and disabilities (SEND).
Further detail on the calculation methodology is provided in the SPD (see link above). The S106 Estimator can be used to calculate indicative contributions for residential development.
Education Contributions updated June 2026.
Contributions support a range of initiatives to help secure employment opportunities for Nottingham residents. These may include:
-
developing a skilled labour pool aligned to vacancies, including apprenticeships and work experience;
-
supporting residents facing barriers to employment through training, qualifications, and equipment;
-
working with developers and contractors to maximise local employment and skills benefits, including through corporate social responsibility commitments.
Activity may take place on development sites or elsewhere in the city (for example, job fairs, community events, workshops, and sector‑based programmes).
A proportion of contributions is used to support the Nottingham Jobs service in coordinating Employment and Skills activity.
The S106 Estimator can be used to calculate indicative contributions for developments with build costs over £1 million.
These estimates relate only to financial contributions. Additional obligations may be secured through an Employment and Training Plan. Early engagement with the Nottingham Jobs team is recommended.
Employment and Training last updated June 2026.
Monitoring and Administration Fees
All S106 agreements are monitored regularly to identify when payment triggers are reached (for example, commencement, completion, or occupation). Contributions become payable at these trigger points.
While developers are expected to notify the Council when triggers are met, this is not always the case. To cover monitoring and administration costs, a fee of 3% of S106 contributions is applied, capped at £7,541.01 (2026). The cap is updated annually in line with the Retail Price Index.
Legal Fees
The Council’s reasonable legal costs for negotiating, preparing, and completing S106 agreements are recoverable from the developer. These are separate from the planning obligation and do not form part of the contribution calculation.’
