Buy to let in St Albans and nearby.

1. The local numbers

The Office for National Statistics publishes average rents and house prices for the whole St Albans district, which includes Marshalswick, Harpenden and Wheathampstead. It doesn’t publish them for each area on its own.

Source: Office for National Statistics, Housing prices in St Albans, read on 14 November 2026. Rents are for September 2026. Prices are for August 2026 and are provisional. The gross yield is our own sum: a year of the average rent, divided by the average price.

Treat the yields as a rough guide, for three reasons:

• They are averages for the whole district, not for one street or one home.
• The rent averages include tenancies that started years ago at lower rents. A home coming to market today will usually let for more than the average for its size, provided it’s well presented and sensibly priced.
• The price averages come from homes that were sold, which aren’t the same homes as the ones being rented.

On these figures, flats and maisonettes show the highest gross yield and detached houses the lowest. That’s what the averages show; it isn’t a recommendation to buy one kind of home over another. Gross yield leaves out running costs, tax and any change in what the home is worth. Our St Albans rent report has the rent figures in full.

2. How to work out the yield

Gross yield is a year’s rent divided by what the home costs. A flat bought for £331,000 and let at £1,487 a month brings in £17,844 a year, which is a gross yield of 5.4%.

Net yield takes off fees and other costs first, so it’s always lower. Our rental yield calculator works out both. It doesn’t allow for income tax or empty periods, so treat the answer as a guide.

The rent is the number people most often guess. Section 9 explains how to get a real one before you buy.

3. Area by area

There’s no official rent figure for each area, but we can tell you what each place is like to let in.

St Albans

Postcodes AL1, AL3 and AL4. St Albans City station is on the east side of the centre and has the fast Thameslink trains, reaching St Pancras in around 20 minutes. St Albans Abbey, on the other side, only has the Abbey Line to Watford Junction. Two addresses at similar rents can mean quite different commutes for a tenant. Our service for St Albans landlords.

Marshalswick

Postcodes AL1 and AL4, north-east of the city centre and about 1.5 miles from it. Marshalswick grew from the 1920s, with a larger estate following from the 1950s. The Quadrant is the local shopping parade and our office is on it. Sandringham School is on The Ridgeway, and St Albans City station is under two miles from The Quadrant by road. Our service for Marshalswick landlords.

Harpenden

Postcode AL5, about five miles from our office. Harpenden has about 31,000 residents, four secondary schools and a Thameslink station, with the fastest trains reaching St Pancras in around 25 minutes. The M1 is close by at junctions 9 and 10. Tenants here often ask about the walk to the station, school admissions and parking. Our service for Harpenden landlords.

Wheathampstead

Postcode AL4, about four miles from our office. A village of about 6,600 people (civil parish, 2021 census), with a historic centre, listed buildings nearby and a conservation area at Amwell. The village station closed in 1965, so the nearest is Harpenden, and a Luton to Hatfield bus runs through the village. Older homes can be harder when it comes to energy ratings and electrical reports, and work on a listed home may need consent first, so find that out before you buy. Our service for Wheathampstead landlords.

4. Before you buy

• Stamp Duty. In England, if buying means you’ll own more than one home, you’ll usually pay 5% on top of the standard Stamp Duty rates. On a £331,000 home that comes to £23,100, against £6,550 at the standard rates. Check your own figure with the GOV.UK Stamp Duty rates and calculator.
• The mortgage. A home bought to let needs a buy-to-let mortgage, not a residential one. We aren’t mortgage advisers, so speak to a broker.
• The energy rating. A let home needs an EPC rating of E or better. The government has consulted on raising that to C by 2030. It isn’t law yet, but look at the rating before you buy.
• A flat? Read the lease. The lease may need the freeholder’s consent before you can let. Check the service charge and ground rent too, because they come out of your rent.
• Insurance. You’ll need landlord insurance rather than ordinary home insurance.

5. The rules since 1 May 2026

Tenancies in England are now month to month, with no fixed terms. The tenant can leave by giving at least two months’ written notice. A landlord can only end a tenancy on a Section 8 ground, such as selling, moving in or serious rent arrears, and each ground has its own notice period. There is no Section 21 notice any more.

You advertise one rent and can’t accept offers above it. You can take at most one month’s rent in advance and a deposit of up to five weeks’ rent. Rent can go up once a year, and not in the first year, using Form 4A with at least two months’ notice. You can’t turn applicants away because they have children or receive benefits, and a pet request must be answered in writing within 28 days.

For anyone buying to let, the point is that you can’t count on a fixed term, or on getting the home back on a set date. Our Renters’ Rights Act guide for landlords has every change and date.

6. Certificates and the landlord database

Before a tenant moves in you need a gas safety certificate (renewed every year), an electrical report (the EICR, every five years), an EPC rated E or better, smoke alarms on each floor, carbon monoxide alarms and a legionella risk assessment. Our free landlord checklist has the full list on one page.

The national landlord database opens on 15 December 2026. Landlords with homes in St Albans register between 15 January and 14 April 2027, at £65 per home per year. You register yourself, using GOV.UK One Login; on our Fully Managed service we add the tenancy and safety information for you. See Register your rental property on GOV.UK.

7. What it costs to run

• Letting agent fees. Our Fully Managed service is 10% + VAT of the rent each month (12% inc. VAT). Let Only is 6% + VAT of the first 12 months’ rent (7.2% inc. VAT), taken upfront from the first month’s rent. Set-up and marketing is £250 + VAT (£300 inc. VAT) for the first let. On a flat let at £1,487 a month, Fully Managed is £148.70 + VAT a month (£178.44 inc. VAT), and Let Only is £1,070.64 + VAT (£1,284.77 inc. VAT). See every fee.
• Empty weeks. Every week a home sits empty costs about 2% of a year’s rent.
• Repairs and upkeep. Boilers, roofs and redecorating between tenants all fall to the landlord, so keep money aside.
• Certificates and registration. The gas check every year, the electrical report every five years, and £65 a year for the landlord database.
• Insurance, and for a flat, the service charge and ground rent.
• Mortgage interest, if you borrow.

If you’re weighing up whether to manage the home yourself, property management in St Albans sets out what a managing agent does each month.

8. Tax, briefly

• Rental profit is taxed through Self Assessment, after allowable expenses.
• From 6 April 2027, property income has its own Income Tax rates: 22% basic, 42% higher and 47% additional. That’s two points above the main rates. GOV.UK sets out the change.
• Mortgage interest isn’t taken off your rent before tax. It gives a tax reduction at the basic rate instead: 20% now, and 22% from April 2027. GOV.UK explains how it’s worked out.
• Making Tax Digital is being phased in for landlords from April 2026, depending on income.
• When you sell, Capital Gains Tax is usually due on any gain.
• Whether to buy in your own name or through a limited company is a question for an accountant.

This is general information, not tax advice. Speak to an accountant about your own position before you buy.

9. Ask us before you buy

If you’re looking at a particular home, ask us what it would let for before you make an offer. We’ll give you a figure based on what similar homes nearby have actually let for. It’s free and there’s no obligation. Call 01727 761816 or send us the details.
