Is SignalLine or Acuity cheaper for a TSM survey?

Acuity does not publish pricing, so a like-for-like figure requires a quote. As sector reference points, human telephone interviewing typically costs £15–£30 per completed response once quotas are met, while AI-phone fieldwork runs £3–£6. SignalLine publishes campaign pricing from £499. For a 1,000-response programme the fieldwork cost difference is usually five figures — but price is only the right deciding factor if both methods otherwise meet your representativeness and governance needs.

Can we use both providers together?

Yes, and mixed-mode designs are described by the Regulator and sector benchmarkers as the methodological gold standard. A workable split is AI-phone for the high-volume main wave with human follow-up — from either provider type — for cohorts that need it. Mode effects within the combined dataset must be acknowledged and, where material, weighted.

Does SignalLine offer benchmarking like Acuity?

No — not at Acuity's depth, and we say so plainly. Acuity's published materials cite around 150 benchmarking members and a historic data bank of over 750,000 residents; that longitudinal comparison base is a genuine strength. SignalLine's reports benchmark your results against the Regulator's published sector-level statistics, which are free and public, but we do not operate a proprietary peer-group benchmarking club.

SignalLine vs Acuity Research & Practice: TSM survey providers compared

Q: Are AI-phone surveys acceptable for TSMs?

AI-phone fieldwork fits within the Regulator of Social Housing's 'telephone' mode and the MRS Code of Conduct, provided the verbatim TSM question wording is used and the methodology is documented in your published summary of approach. The Regulator has not published AI-specific guidance as of July 2026, so document the rationale — the same discipline any mode change requires.

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 published materials describe more than 27 years of consultancy in the sector, a virtual call centre of over 80 interviewers, more than 320 telephone projects a year, over a million calls and 160,000+ interviews annually in a range of languages, and postal and digital fieldwork alongside telephone. It is Market Research Society certified and holds ISO 9001, ISO 27001 and Cyber Essentials Plus. Its benchmarking base — around 150 member organisations and a historic data bank of over 750,000 residents — is one of the largest in the sector.

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, at £3–£6 per completed response rather than the £15–£30 typical of human telephone interviewing, with verbatim TP01–TP12 wording enforced by the system, 15+ languages auto-detected mid-call, and an audit-ready summary-of-approach pack when the campaign closes. Published campaign pricing starts at £499.

2. The comparison, honestly

Dimension	Acuity	SignalLine
Fieldwork model	Human interviewers (80+), plus postal and digital	AI voice agents by phone
Typical cost per completed phone response	Not published; sector human-phone range is £15–£30	£3–£6
Fieldwork pace	Bounded by interviewer capacity and calling hours	Concurrent calling; thousands of completes in weeks
Benchmarking	~150-member club, 750k-resident historic bank	Against RSH published sector statistics only
Track record	27+ years in social housing research	New entrant, AI-native
Interviewer effect on scores	Present, as with any human-administered mode	Reduced — no social-desirability pressure from a person
Qualitative depth / follow-up research	Full-service research consultancy	Structured survey fieldwork and reporting
MRS Code of Conduct	Applies — MRS certified	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, a 27-year 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. At sector-typical rates, 1,000 completed human phone interviews cost £15,000–£30,000 in fieldwork alone; AI-phone runs £3,000–£6,000. For stretched insight budgets that difference funds the rest of the programme.
The deadline is close. Concurrent calling compresses a 6–10 week telephone fieldwork phase dramatically — relevant if you are reading this in spring with a 30 June NROSH+ deadline approaching.
Consistency matters to you. Every call uses identical verbatim wording, tone and ordering — there is no interviewer variance to quality-control, and the interviewer effect on satisfaction scores is reduced.
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; we share our own campaign data under NDA instead. 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. Sector reference points: human telephone £15–£30 per completed response, AI-phone £3–£6. SignalLine campaign pricing is published and starts at £499.

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.
