Damp and mould sensors for landlords, and where Awaab’s Law stands
Six damp and humidity sensors and monitoring services, with the price each maker publishes, read on its own site on 24 October 2026; then where Awaab’s Law stands for private renting and what GOV.UK says about sensors. Listed A to Z, not ranked. LetCompliance, the software that runs the let and the repair a reading points to, is set out first and reads no sensor.

LetCompliance, the publisher’s own software
Runs the let beside every firm here
Landlord software for the whole let: adverts and applications, the tenancy and its signatures, rent and Direct Debit, arrears and the Section 8 notice, repairs, deposits, certificates and Making Tax Digital for UK property income.
From £7.99 a month for one property.
Awaab’s Law does not apply to private landlords yet: it has applied to social housing since 27 October 2025, and the government’s consultation on extending it to private rented tenancies, published on 9 October 2026, runs to 18 December 2026 and gives 2027 as the earliest feasible date. The sensors here cost from £16.99 (SwitchBot Meter) to £109.99 (Netatmo) to buy, or from £15 a month per property plus VAT monitored (ResiSure), read on 24 October 2026. LetCompliance runs the let around the repair a reading points to: the tenant’s report with photos, a response clock, the contractor and the dated record of each visit. From £7.99 a month for one property.

What LetCompliance does beside a sensor
A sensor shows a reading. LetCompliance runs the let around the repair it points to: the tenant’s report with photos, a response clock, the contractor, and the dated record of each visit.
The tenant reports it, with photos
Damp, mould or a leak reported in the tenant portal with photos, or logged by you from a phone call, in one inbox with the tenant’s messages.
On every plan
A response clock on every repair
Each repair gets a priority and a clock: emergency 24 hours, urgent 7 days, routine 14 days. These are LetCompliance’s own defaults, with the social housing timings of Awaab’s Law as a guide only.
On every plan
A first read of the report
AI repair triage suggests the priority, the trade, who is probably responsible and a brief for the contractor. You decide.
On every plan
Inspections with dated photos
Mid-tenancy visits with a checklist, dated photos and a report PDF, and a day planner that sends each household written notice of the visit. This is the record of each home’s condition, and when it was last checked, that GOV.UK advises.
On every plan
The contractor and the job
Your contractors, the properties each covers, and the job sent with the quote to approve and the work history with its cost.
On paid plans and the trial
What was done, and what it cost
The maintenance log keeps each job with its cost, warranty and photos, against the property.
On every plan
What it does not do. LetCompliance does not read sensor data or sell sensors, and gives no legal advice. Its repair clocks are its own defaults, not a timetable the law sets for private landlords.
LetCompliance publishes this guide and is landlord software. It is not one of the firms compared below and is not ranked against them.
Plans are one price for each size of portfolio, never a charge per property, a month: £7.99 for 1 property, £14.99 for up to 3, £19 for up to 10, £29 for up to 20 and £49 for any number. Every new landlord account starts with a 3-day trial and no card.

The fixed part
Where Awaab’s Law stands, and what GOV.UK says about sensors
- Awaab’s Law has applied to social housing since 27 October 2025, for damp and mould and all emergency hazards. Draft regulations for a second phase, adding more hazards in social housing, were laid on 13 July 2026, to come into force on 30 November 2026 if Parliament approves them.
- It does not apply to private landlords yet. The Renters’ Rights Act 2025 (section 60, and section 61 for licences) provides for extending it, through regulations still to be made. The government’s consultation on doing so was published on 9 October 2026, closes at 11:59pm on 18 December 2026, and gives 2027 as the earliest feasible date (GOV.UK).
- Until then, existing law sets a private landlord no specific timescale: repairs are to be carried out within a reasonable period of time once the landlord is told of the problem, as the consultation puts it.
- GOV.UK’s damp and mould guidance says smart sensors may help to monitor temperature, humidity and indoor air quality, that they should not be misused as tools to blame tenants, and that they should be installed only with the tenants’ consent and understanding. For individual landlords it advises keeping a record of each home’s condition and the date it was last routinely checked (GOV.UK, updated 1 April 2026).
Before you choose
What to check
The tenant’s consent
Agree before anything goes in: what is measured, who sees the readings and how long they are kept. GOV.UK says sensors should be installed only with the tenants’ consent and understanding.
Readings from a home someone lives in
Readings from an occupied home can say a lot about the people living there. Check the Information Commission’s guidance at ico.org.uk before you collect them.
A reading is not a repair
High humidity points to a cause to find: ventilation, heating, insulation or a leak. GOV.UK is clear that damp and mould are not to be blamed on tenants’ everyday living.
Bought or monitored
A display or a logger costs once and is read on a visit; a monitored service sends reports and costs every month. Price both over the years you will keep it.
Before you rely on this page
This page is not legal advice. Awaab’s Law does not apply to private landlords today, and no law requires a landlord to install a damp or mould sensor.
It sets out what each maker publishes, read on one day, and repeats no maker’s claim about accuracy or results. No link on this page earns LetCompliance a fee.
Method
How this page was put together
- Fees: each firm’s own pages, read on 24 October 2026, without making an account or asking for a quote. Pages that draw their prices in the browser were read in one. Every fee is given as the page gave it, with VAT as the page states it, and a fee a page does not publish is marked as not published.
- Registers: the Solicitors Regulation Authority, the Council for Licensed Conveyancers and the Financial Conduct Authority registers where a firm is regulated, Companies House for the company behind each firm, and Companies House’s published list of authorised agents (dated 21 October 2026), all read the same day. Where a firm’s pages give no company number, the company found on the register under the name it gives or trades as is shown, and the cell says so.
- Not ranked: the firms are listed A to Z. Nothing was bought or tried; this is a desk comparison of published pages and public registers. Any link that pays LetCompliance a fee is marked Sponsored; the links here go to the pages that were read.
- LetCompliance publishes this guide and makes landlord software. It is set out first because it is the publisher’s own product, and it is not compared with the firms.

FAQs
Questions landlords ask
Does Awaab’s Law apply to private landlords?
Not yet. It has applied to social housing since 27 October 2025. The Renters’ Rights Act 2025 provides for extending it to private rented tenancies through regulations, and the government’s consultation, open until 18 December 2026, gives 2027 as the earliest feasible date. Until then a private landlord must carry out repairs within a reasonable period of time once told of the problem.
Do landlords have to install damp and mould sensors?
No law requires one. GOV.UK’s damp and mould guidance says sensors can help, should be installed only with the tenants’ consent and understanding, and should never be used to blame tenants. What it advises for individual landlords is a record of each home’s condition and the date it was last checked.
How much does a damp and mould sensor cost?
On the prices published on 24 October 2026: from £16.99 (SwitchBot Meter) and £18 (FireAngel FA7312) for a hygrometer, £60.50 excluding tax for a Lascar data logger, £109.99 for a Netatmo air quality monitor, and from £15 a month per property plus VAT for ResiSure’s monitored service.
Can I put a sensor in a tenant’s home?
Only with the tenant’s consent and understanding, as GOV.UK’s guidance says. Agree what is measured, who sees the readings and how long they are kept, and check the Information Commission’s guidance at ico.org.uk before you collect them.
Does LetCompliance read sensor data?
No. LetCompliance runs the let around the repair: the tenant reports it with photos in the portal, the repair gets a priority and a response clock, the job goes to your contractor, and each inspection is kept with its dated photos.
