What Our Landlords Say

Trusted by thousands of property owners across the UK

RentalBux finally gave me peace of mind.


Even after trying several tools, I was struggling with my portfolio of three rentals. MTD just added to that struggle. But then, I was introduced and all my worries disappeared. MTD submissions in minutes, track each property separately, allocate profit sharing. Wow!

Switching to RentalBux was one of the best decisions I made. Especially the joint-ownership module. Our family property had three owners with different shares, and RentalBux handled it quite efficiently.

Real challenges landlords face, and how RentalBux solves them

Real challenges Landlords face How RentalBux Solves It
Generic accounting tools aren't tailored to rental or property businesses. RentalBux is built specifically for landlords, supporting both UK and foreign property portfolios.
Hard to juggle multiple income streams, properties, and shared-ownership structures. Manage multiple properties, units, and income streams in one dashboard with separate workspaces per business line.
Worried about MTD ITSA compliance and keeping digital records up to date. RentalBux is HMRC-recognised MTD software with digital records, quarterly updates, and submission workflows baked in.
Using spreadsheets and disconnected tools for property management, accounting, and tax. All-in-one platform for lease documents, rent tracking, bank feeds, and expense capture—no more fragmented workflows.
Scaling becomes messy when portfolios grow (HMOs, multiple owners, more units). Flexible pricing tiers and scalable workspaces support portfolios from a single unit to large, multi-owner holdings.
Manual bookkeeping is time-consuming and error-prone (missed rent, maintenance, double entry). Automated bank sync, rent scheduling, and real-time notifications cut admin time and reduce mistakes.
Accounting software costs are high for small landlords with just one property. RentalBux offers a free plan for one property until March 2028, removing the cost barrier for getting started.
