If you are shortlisting TSM survey providers, Acuity Research & Practice is very likely on your list — and deservedly so. This page is written by SignalLine, so read it knowing where it comes from. We have tried to make it the comparison we would want to read ourselves: specific about what Acuity does well, specific about where AI-phone fieldwork genuinely changes the economics, and clear that the two approaches solve the same regulatory requirement in structurally different ways.
1. Who the two providers are
Acuity Research & Practice
Acuity is one of the established names in UK social housing research. Its own website describes research and consultancy for the social housing sector, telephone surveys conducted by its own trained interviewers, face-to-face, online and postal surveys alongside them, and benchmarking clubs for housing providers. Check its current accreditations and capacity with Acuity directly.
SignalLine AI
SignalLine runs TSM perception surveys with conversational AI voice agents over the phone. The pitch is structural rather than incremental: fieldwork that runs concurrently rather than interviewer-by-interviewer, with no interviewer time in the price, verbatim TP01–TP12 wording enforced by the system, 15+ languages auto-detected mid-call, and an audit-ready summary-of-approach pack when the wave closes.
2. The comparison, honestly
| Dimension | Acuity | SignalLine |
|---|---|---|
| Fieldwork model | Human telephone interviewers, plus face-to-face, online and postal | AI voice agents by phone |
| Pricing | Not published; quoted per project | Published per completed response on our pricing page |
| Fieldwork pace | Bounded by interviewer capacity and calling hours | Concurrent calling, not bounded by interviewer numbers |
| Benchmarking | Member clubs comparing housing providers | Against RSH published sector statistics only |
| Track record | Established in social housing research | New entrant, AI-native |
| Interviewer effect on scores | Present, as with any human-administered mode | No human interviewer; its effect on scores is not yet measured |
| Qualitative depth / follow-up research | Full-service research consultancy | Structured survey fieldwork and reporting |
| MRS Code of Conduct | Applies — Acuity states it complies | Applies — fieldwork designed to the Code |
3. When Acuity is the better fit
- You buy on benchmarking.If year-on-year peer comparison against a large member base is central to how your board reads satisfaction data, Acuity’s benchmarking bank is a real, hard-to-replicate asset.
- You want a full-service research partner. Deep-dive qualitative work, resident focus groups, bespoke studies alongside the TSM tracker — an established consultancy does this; we do not.
- Your governance is conservative about AI. If your board or scrutiny panel is not ready to defend AI fieldwork in the published summary of approach, an established human-interviewer track record is the easier sign-off — and that is a legitimate reason to choose it.
4. When SignalLine is the better fit
- Fieldwork cost is the constraint. Interviewer time is the biggest cost in human telephone fieldwork, and AI-phone fieldwork takes it out. Compare written quotes for the same achieved sample.
- The deadline is close. Calls run concurrently rather than one interviewer at a time, so the pace of fieldwork is not bounded by how many interviewers are on shift — relevant if you are reading this in spring with a 30 June NROSH+ deadline approaching. Ask every provider for a dated fieldwork timeline for your sample.
- Consistency matters to you. Every call uses identical verbatim wording, tone and ordering — there is no interviewer-to-interviewer variance to quality-control.
- Multilingual reach. Language switching happens mid-call automatically rather than by scheduling a specialist interviewer callback.
5. The honest caveats on our side
Three things we tell prospects directly. First, the Regulator has not published AI-phone-specific guidance as of July 2026 — AI fits the telephone mode and the MRS Code, but your summary of approach must document the methodology, and we help draft that. Second, there is no published TSM-specific response-rate benchmark for AI-phone fieldwork yet, so judge us on a sample: we send a first sample call on your own questions in about 48 hours. Third, some tenants simply prefer talking to a person, and a well-designed programme can accommodate that — which is why mixed-mode, potentially including a human-interviewer partner, is sometimes the right answer. Our methodology guide covers those trade-offs mode by mode, with the sector mode-effect data in full.
Frequently asked questions
Is SignalLine or Acuity cheaper?
Acuity does not publish pricing, so compare written quotes for the same achieved sample. Our own price per completed response is on our pricing page.
Are AI-phone surveys acceptable for TSMs?
Yes — within the Regulator’s telephone mode and the MRS Code, with verbatim wording and a documented methodology. No AI-specific RSH guidance exists as of July 2026, so the documentation discipline matters.
Can we use both?
Yes. Mixed-mode is the sector’s methodological gold standard; AI-phone main wave plus targeted human follow-up is a defensible design.
