Rent & bills estimator
Enter a postcode (or just the first part, e.g. E1) and we'll find the area and estimate rent plus monthly bills.
Up to 2 occupants per bedroom.
Overrides the Band average – check your council's bill
Our estimate, not ONS data: tired −10%, well maintained as published, high spec +15%. Each extra bathroom counts +4%, and floor area moves the rent by up to 15% (never more than a quarter in total).
How this is estimated: the published rent for that number of bedrooms and property type in your area, or your region's average where the ONS does not publish the area. Bathrooms, floor area and condition can then move it by up to a quarter either way – they cannot turn a typical home into a different one. Rent figures: ONS Price Index of Private Rents, September 2026. The range is ±8%. Bills use 2026/27 estimates – you can type your own figure for any bill.
Under the Renters' Rights Act a landlord advertises one fixed asking rent, and a tribunal compares any increase with the open market rent for similar homes nearby – so check recent adverts as well as this average.

Add a mortgage below to see the difference it makes.
Interest-only. Shown separately because it isn't part of the standard net yield.
Gross yield = (annual rent ÷ property value) × 100
Net yield = ((rent collected − running costs) ÷ property value) × 100
Tax and mortgage capital repayments are not included.
We can confirm achievable rent and the costs that actually apply to your area.
Figures are indicative estimates only and do not constitute a valuation or financial advice.
