“When are TSMs actually due?” has a two-part answer, because the regime separates submitting data to the Regulator of Social Housing (RSH) from publishing it to your tenants — and the deadlines, the audiences, and the required contents differ. This guide sets out the 2026/27 calendar as it stands in July 2026, what goes in the NROSH+ return, the publication checklist for your own website, and where the new electrical safety TSM lands in the timeline.
1. The calendar at a glance
The TSM reporting year is 1 April to 31 March. Perception-survey fieldwork can run at any point within it — annually, in waves, or as a rolling tracker — provided the data you report was collected within the reporting year. Submission happens after the year closes.
| Milestone | Date | Status |
|---|---|---|
| 2025/26 TSM Return window (NROSH+) | 1 April – 30 June 2026 | Closed |
| 2026/27 reporting year | 1 April 2026 – 31 March 2027 | In progress — fieldwork runs now |
| Electrical safety TSM in effect | 11 June 2026 | Live — first reported for 2026/27 |
| 2026/27 TSM Return window (expected) | 1 April – 30 June 2027 | Confirmed each year in the CEO letter |
| Sector-level statistical release | Late autumn (2024/25 came out 4 Nov 2025) | Annual pattern |
The submission window has followed the same shape every year of the regime so far: the return opens on 1 April and closes on 30 June following the reporting-year end. RSH confirms the exact dates annually in its CEO data-requirements letter (signed by Will Perry, Director of Strategy, for 2026/27). Treat the 30 June deadline as fixed for planning purposes; treat anything more precise than that as unconfirmed until the letter for the year in question lands.
If you own other regulatory returns too, note the adjacent deadlines from the same letter: the Statistical Data Return closed 31 May and the Financial Forecast Return shares the 30 June date with the TSM Return. June is congested — plan sign-off accordingly.
2. Who submits, who publishes
Two obligations, two thresholds:
- 1,000+ units: submit all TSMs to RSH annually through the NROSH+ portal and publish them, with supporting information, on your own website.
- Under 1,000 units: no submission to the Regulator is currently required — but you must still generate and publish TSMs, with proportionate requirements: the perception survey can run once every two years rather than annually, a high-level representativeness check substitutes for formal weighting, and a census approach is acceptable for very small stocks.
The threshold counts combined Low Cost Rental Accommodation and Low Cost Home Ownership stock. If an acquisition or transfer takes you over 1,000 units mid-year, the submission obligation is worth clarifying with RSH early rather than discovering it in June.
3. What must be published on your own website
Publication is not a courtesy copy of the return — it has its own required contents, and RSH expects it to be “timely, clear, and easily accessed by tenants.” The checklist:
- All 22 measures (23 from 2026/27 with electrical safety for large landlords): building safety BS01–BS05, management measures CH01, CH02, NM01, RP01, RP02, and the twelve perception measures TP01–TP12.
- Your target timescales for the repairs measure (RP02) and the complaints measure (CH02), so the percentages published against them are interpretable.
- A summary of approach covering the collection method(s) used and “an assessment of the representativeness of the survey responses” used to generate the perception measures — plus sampling method, weighting, exclusions, incentives, and named external contractors.
- The full questionnaire actually used, including “any additional questions and introductory or explanatory wording communicated to tenants.” If your survey provider added a warm-up question or reworded the intro script, that is now a publication item, not an internal detail.
For what the summary of approach must contain in full, and the five compliance pitfalls that have led RSH to exclude named landlords’ data from the published statistics, see our complete TSM guide.
4. New for 2026/27: the electrical safety TSM
The first new measure added to the framework since launch took effect on 11 June 2026. Large landlords (1,000+ homes) publish it for the first time for the 2026/27 reporting year; small landlords for reporting years ending 31 March 2027 onwards. It is a management-information measure — no survey required — reporting the proportion of homes where all required electrical safety checks have been completed and recorded, measured as at the last day of the reporting year. The first published results will therefore reflect the position at 31 March 2027.
“The new TSM does not change landlords’ duties in meeting legal requirements relating to electrical safety… The building safety TSMs aim to provide a baseline level of assurance.” — Will Perry, Director of Strategy, RSH
The 2026/27 CEO letter also flags “some minor changes to the TSM Return” itself, while confirming that the requirements for collecting and calculating the TSMs have not changed. In other words: your survey methodology carries over; your year-end data pack gains a line.
5. Working back from 30 June
The submission deadline is the visible end of a chain that starts months earlier. A defensible working-back plan for the 2026/27 year:
- By 31 March 2027 — fieldwork complete; all perception responses collected within the reporting year; electrical safety and other building-safety compliance positions recorded as at year-end.
- April 2027 — analysis, weighting, and the representativeness assessment; draft summary of approach.
- May 2027 — board (or delegated committee) sign-off of the published TSMs; website publication prepared.
- By mid-June 2027 — NROSH+ return submitted, two weeks clear of the deadline. The portal gets queue-loaded close to the cut-off, and June is congested with other returns.
If the fieldwork itself is the bottleneck — panel fatigue, interviewer capacity, a compressed tail — the fix belongs in the programme design, not the June scramble. Our 12-week TSM programme guide covers the operational timeline in week-by-week detail, and the methodology guide covers how mode choice trades off speed, cost and representativeness.
Frequently asked questions
When is the 2026/27 TSM deadline?
Expect the NROSH+ return to open 1 April 2027 and close 30 June 2027, following the pattern confirmed in each annual CEO letter. The 2025/26 return closed 30 June 2026.
Do small providers submit to NROSH+?
No — providers under 1,000 units publish TSMs but do not currently submit them to the Regulator. Proportionate requirements apply, including biennial perception surveys.
Does the electrical safety TSM need a survey?
No. It is a management-information measure reporting completed electrical safety checks as at year-end — first published results reflect 31 March 2027.
Who do we contact with a submission problem?
The RSH referrals and regulatory enquiries team: NROSHenquiries@rsh.gov.uk or 0300 124 5225 — before the deadline, not after it.
