What Is the Rental Yield in Slough?

Gross rental yield is calculated as annual rent divided by asking price, expressed as a percentage. A yield above 5% is generally considered strong for buy-to-let in the UK. Here is how Slough performs across each bedroom count.

BedroomsAvg Asking PriceAvg Monthly RentGross Yield
1-bed£222,400£1,2576.8%
2-bed£362,735£1,7725.9%
3-bed£476,500£2,0415.1%

What is a good rental yield? A gross yield above 5% is generally considered strong for a buy-to-let property in the UK. The national average is approximately 4.5%. Remember that net yield — after accounting for void periods, maintenance, insurance, management fees, and Section 24 tax restrictions — will be lower than the gross figure.

Gross yield = (monthly rent × 12) ÷ asking price × 100. Based on current listing data from PropertyData.co.uk.

How Much Is Stamp Duty on a Buy-to-Let in Slough?

Buy-to-let purchases are classified as additional properties and attract a 5% Stamp Duty Land Tax (SDLT) surcharge on top of the standard rates. This surcharge was increased from 3% to 5% in October 2024. Here is what you can expect to pay at average asking prices in Slough.

Is Slough Good for Student or HMO Lettings?

Slough does not have a major university campus, so student-specific HMO demand is limited. However, shared housing demand from young professionals and key workers can still support HMO lettings in the right areas.

HMO Licensing in Slough

Slough Borough Council operates one of the most aggressive Additional Licensing regimes in the South East, covering the entire borough. Any HMO with 3+ occupants from 2+ households requires a licence anywhere in Slough. Enforcement is active and unlicensed letting carries heavy fines.

HMO licensing level: AdditionalThis council operates Additional Licensing beyond the standard mandatory scheme. More properties need licences, and compliance costs are higher. Check coverage areas before investing.
05

Should You Invest in Slough as a Landlord?

Slough offers solid gross yields, with the best-performing 1-bed properties achieving 6.8%. While not a major student town, professional and family rental demand supports consistent occupancy.

Key strengths: Above-average yields at accessible price points. Growing local economy supports long-term rental demand. Familiar SDLT regime for English investors.

Considerations: The stricter HMO licensing regime means higher compliance costs — factor licence fees and property standards into your budget. The 5% SDLT surcharge (since October 2024) adds to upfront costs. Always account for void periods, maintenance reserves, and Section 24 tax restrictions when calculating net returns.
