Hammock review — what is it and who is it for?

Hammock is a UK-built landlord accounting platform founded in 2019 and backed by $5.5m in funding. It was the first landlord-specific software to be recognised by HMRC as Making Tax Digital-compatible — a meaningful distinction that reflects Hammock’s tight focus on property tax compliance rather than broader property management.

Where Hammock differs from Landlord Studio is in its deliberate narrowness. Hammock does not try to be an all-in-one platform. It focuses almost entirely on the financial layer of landlord management — bank feeds, automated transaction reconciliation, SA105 tax categories, MTD quarterly submissions, investment analytics, and tax bill forecasting. Tenant management, rent collection, maintenance tracking, and tenant communications are explicitly outside its scope.

This makes Hammock the right choice for a specific type of UK landlord: someone who either uses a letting agent for day-to-day management or is happy to handle tenant communication separately, and whose priority is having the cleanest possible financial records and the most automated MTD compliance process available. It is also the tool that many UK accountants recommend to their landlord clients — partly because its workflow is designed around accountant collaboration.

Hammock review — key features for UK landlords

Automated bank reconciliation — the standout feature

Hammock’s strongest feature is its real-time automated bank reconciliation via Open Banking. You connect your bank accounts once — Hammock is FCA-registered (no. 911254) as an Authorised Payment Institution, providing a higher level of regulatory trust than unregistered bank connection services — and all incoming and outgoing transactions are automatically identified, matched to the relevant property and tenancy, and categorised against the appropriate SA105 tax category. For landlords with multiple properties and bank accounts, this eliminates the hours of monthly manual reconciliation that makes landlord bookkeeping genuinely painful.

Running tax bill estimate

One of Hammock’s most practically useful features is its live tax bill estimate, updated throughout the year as transactions are reconciled. Rather than discovering your tax bill in January when Self Assessment is due, Hammock gives you a continuously updated estimate of what you’ll owe based on your current income and expenses. The platform also has a tax savings feature that lets you set aside funds throughout the year specifically for tax — so the money is available when the bill arrives rather than being spent on other things.

MTD quarterly submissions — direct to HMRC

Hammock was the first landlord-specific software to receive HMRC recognition for Making Tax Digital for Income Tax. Quarterly updates are submitted directly to HMRC from within the platform, with your SA105 property income categories automatically mapped from your reconciled transactions. The property tax statement is updated in real time, so your quarterly submission is largely a review-and-confirm process rather than a data entry exercise.

Investment analytics

Hammock provides a level of buy-to-let investment analytics not available in most landlord accounting tools — real-time loan-to-value ratios, rental yields by property, occupancy rates, and per-tenant arrears balances. For landlords who think of their portfolio as an investment to be actively managed rather than just a tax compliance obligation, these metrics are genuinely useful for decision-making — whether to remortgage, which properties are underperforming, where arrears are building up.

Accountant collaboration

Hammock is designed to work with accountants as well as self-filing landlords. Your accountant can be given access to your Hammock account to view real-time data, prepare tax statements, and submit MTD returns on your behalf. For landlords who use an accountant for their tax affairs, this collaborative access means your accountant always has up-to-date, reconciled data rather than needing to wait for a spreadsheet at year-end. Several UK accounting firms — including some that specialise in landlord clients — actively recommend Hammock and include it with their landlord service packages.

Compliance reminders

Hammock sends notifications and alerts about expiring documents and certificates — gas safety, EICRs, insurance, and other compliance deadlines. While this is not as comprehensive as the compliance tracking in a full property management platform, it provides a useful safety net for landlords who might otherwise miss a renewal deadline.

Hammock review — frequently asked questions

Is Hammock HMRC-recognised for MTD?

Yes — Hammock was the first landlord-specific software to receive HMRC recognition for Making Tax Digital for Income Tax. It supports direct quarterly updates and annual Final Declarations to HMRC. See GOV.UK for the full list of HMRC-recognised software.

How much does Hammock cost?

Hammock charges £8+VAT per month (Basic, 1-3 properties), £15+VAT per month (Standard, 4-10 properties), £25+VAT per month (Plus, 11-20 properties), and £31.50+VAT per month and above (Beyond, 21+ properties — scaling per additional property). All prices are plus VAT. The subscription is a tax-deductible allowable expense for your rental business. Contact Hammock for pricing on portfolios of 20+ properties. A free trial is available — check Hammock’s website for current terms.

Does Hammock do rent collection?

No — rent collection is explicitly outside Hammock’s scope. Hammock monitors and reconciles rent payments automatically once they appear in your connected bank accounts, but it does not initiate or process rent payments directly. Landlords who need rent collection automation should use a letting agent or a platform like Landlord Studio which includes automated rent collection on its Pro plan.

Is Hammock FCA regulated?

Yes — Hammock is registered with the Financial Conduct Authority (FCA) as an Authorised Payment Institution (registration no. 911254). This provides an additional layer of regulatory trust for the Open Banking connections that power Hammock’s automated bank reconciliation. This FCA registration is a meaningful differentiator compared to bank connection services that operate without FCA oversight.

Can my accountant access Hammock?

Yes — Hammock supports accountant collaboration. You can give your accountant access to your Hammock account to view real-time reconciled data, prepare tax statements, and work on your MTD submissions. Note that Hammock currently does not support agent filing — the accountant can prepare submissions but the final submission must be authorised by the landlord directly.

Hammock or Landlord Studio — which is better?

They solve different problems. Hammock is better for accounting, MTD compliance, investment analytics, and working with an accountant. Landlord Studio is better for self-managing landlords who want one platform for the complete portfolio workflow — tenants, maintenance, rent collection, and accounts. If you use a letting agent and primarily want the best financial compliance tool, Hammock. If you self-manage and want everything in one place, Landlord Studio.

Hammock review — the bottom line

Hammock is the most focused and polished landlord accounting and MTD compliance tool available to UK buy-to-let landlords in 2026. The real-time bank reconciliation, running tax estimate, and investment analytics are genuinely best-in-class for the accounting layer of landlord management. The FCA registration and first-mover HMRC recognition give it a strong compliance credibility that newer entrants lack.

The deliberate narrowness is both Hammock’s strength and its limitation. It does accounting exceptionally well — and nothing else. Landlords who need a complete management platform will find it insufficient. Landlords who use a letting agent and primarily need clean financial records, automated MTD compliance, and investment performance insight will find it ideal.

At £8+VAT/month for up to 3 properties, it’s excellent value for what it does. If your primary concern is getting MTD right and having real-time visibility of your tax position, Hammock earns its place in your landlord toolkit.
