In the UK, owning a second home used to give you a bolt-hole to escape to during the school holidays with the family, and it could provide a little nest egg in the future.  These days, although there are still many holiday retreats in picturesque coastal locations, the main reasons behind multiple property ownership are changing.

Increasingly, second (and third, fourth, etc) homes serve as part of a property portfolio strategy to benefit from different markets.  Excluding the Student HMOs, which we’ve discussed here, there are generally three markets that we’ve found our landlords are tapping into: holiday hotspots, large engineering projects, and the city pied-a-terre.  

However, regardless of where and why you’re looking to expand your portfolio to, understanding the legislative landscape, financial implications, taxes, and critical considerations around second home ownership is essential for making informed and profitable decisions.

1. Holiday home hotspots

The perennial leaders for second-home popularity remain the ever-popular classics:

• Historically, Cornwall and Devon, with their endless coastlines and breathtaking scenery, continue to host huge numbers of second homes, especially in places like St Ives, Salcombe, and Saundersfoot. Cornwall alone has over 9,400 second properties, offering both leisure and investment appeal.

• More recently, Southwold, Teignmouth, Bournemouth, Ramsgate in the south and southeast are challenging for the most desirable addresses for seaside escapes, with warmer weather and strong letting demand during the summer months.

• Surprisingly, Kensington & Chelsea, Westminster (London), also see significant second home ownership, catering more to luxury urban living than holiday lets. These areas attract international buyers and business professionals seeking a base in the capital.

2. Large engineering projects

Major civil engineering projects create a unique demand for second homes due to the length of the project, and the relatively consistent demand for temporary or longer-term accommodation for workers and professionals:

• London: The capital dominates not just for leisure and investment, but also as the headquarters for many consulting and engineering services. High-value flats and serviced apartments cater to short and mid-term stays.
• Belfast, Leeds, Liverpool, Birmingham: Regional cities are increasingly attractive to business travellers and contractors, sometimes offering better living value and amenities for weekly lets than London. These cities also benefit from proximity to client sites and lower average rents.

• Oxford & Cambridge: With strong research and tech sectors, frequent corporate project work leads to high demand for short and medium-term accommodation, blending academic, engineering, and business needs.

Legislation and regulatory considerations

Second homeownership in the UK involves navigating a complex array of local and national regulations. Local authorities have their own rules and policies regarding second homes, reflecting the impact on housing availability and community dynamics.

• Council Tax premiums: Many councils impose a higher council tax rate on second homes – often 100% extra or more – as a disincentive to owning property that is not a primary residence.
• Planning restrictions: Some areas, especially rural and coastal zones heavily affected by second homes, have introduced restrictions aiming to limit new second homes or change-of-use permissions. Councils may require owners to demonstrate how they intend the property to be used or restrict holiday lets to protect local housing stock.
• Stamp Duty Land Tax (SDLT): Buyers of second properties in England and Northern Ireland must pay a 3% surcharge on top of the standard SDLT rates. This can add tens of thousands of pounds to purchase costs, depending on the property’s value. Scotland and Wales have their own additional transaction taxes with similar surcharges.
• Licensing and letting regulations: If the second home is let commercially – whether as a holiday let, corporate weekly let, or longer-term tenancy – owners must comply with fire safety, health regulations, and possibly licensing schemes such as selective or mandatory licensing for Houses in Multiple Occupation (HMOs).
• Capital Gains Tax (CGT): When selling a second home, CGT is due on any gain above the primary residence exemption. This tax liability can be significant for properties held over many years and appreciating in value.

Financial positives and what to seriously consider 

• Capital appreciation: Property near major infrastructure sites and in sought-after urban centres often sees value uplift driven by demand from project workers and business travellers. However, owners should assess market trends carefully, as projects can fluctuate and local demand may shift after project completion.

• Increased holding costs: Besides council tax surcharges and higher insurance premiums for second homes (due to risks from vacancy and different usage), maintenance and management fees also add up. Professional property management is often necessary if renting out to multiple tenants or short-stay clients.

• Tax implications: Aside from upfront SDLT and ongoing council tax rates, rental income attracts income tax and must be declared. Owners should keep thorough records to maximise allowable deductions like mortgage interest (within current legislative limits), maintenance, and letting agent fees.

• Mortgage and financing: Financing second homes typically requires larger deposits (commonly 25% or more) and higher interest rates than primary residences. Lenders also assess rental income potential strongly when approving loans, especially for business lets or properties near civil project sites.

Second homes in civil engineering and business hubs 

Owning a second home near major civil engineering projects, power stations such as Sizewell B, or energy hubs creates opportunities distinct from traditional holiday homes:

• Stable rental demand: Projects lasting several years ensure a continuous influx of engineers, contractors, and specialists needing accommodation, reducing vacancy risk.
• Flexibility for business travellers: City apartments in hubs like London, Leeds, Birmingham, and Cambridge cater to professionals requiring weekly or short-term stays. These can command premium rents due to convenience and amenities versus hotels.

Long-term investment in infrastructure zones: Locations adjacent to net zero initiatives, major transport projects, or energy installations often benefit from government support, job creation, and infrastructure improvements, supporting property appreciation.

Serious considerations before buying

As with all decisions, there are pros and cons.  Although investing in your property portfolio can sound like a no-brainer, you need to consider the legislative situation before taking the plunge  

These are the legislation, taxes, and stamp duties related to multiple home ownership in the UK, reflecting the latest updates for 2025 at time of writing:

Legislation and regulatory framework

• The UK government has given local councils in England the right to impose up to a 100% council tax premium on second homes starting April 2025 under the Levelling Up and Regeneration Act 2023. This means second homeowners could pay double the standard council tax rate unless exemptions apply. Many councils have adopted or plan to adopt these increased premiums.
• Planning restrictions in some regions limit the number of second homes or their use, especially in rural and coastal areas, to address housing availability and community impact.
• If the second home is let commercially (holiday lets, HMOs, business lets), additional licensing, health, and safety regulations apply.
• The Renters’ Rights Bill and Leasehold and Freehold Reform Act 2024 are introducing reforms that may affect tenancies and leaseholds related to second and multiple homes, including abolishing some eviction routes and easing lease extension processes.

Taxes

• Stamp Duty Land Tax (SDLT): From April 6, 2025, buyers of second homes pay a 3% surcharge on top of the standard SDLT rates. This surcharge applies to holiday homes, buy-to-let, and additional properties, making purchasing second or multiple homes considerably more expensive.
• Income Tax: Rental income from second homes must be declared and is subject to income tax. Allowable deductions include mortgage interest (up to legislated limits), maintenance, and letting agent fees, which require careful record keeping.
• Capital Gains Tax (CGT): When selling a second home, CGT applies to gains above the primary residence exemption, which can be a significant liability depending on the property’s appreciation.

Financial and practical considerations

As can be seen above, multiple home ownership involves higher holding costs, plus often increased insurance premiums and maintenance or management fees.  Mortgages for second homes often require larger deposits and higher interest rates, with lenders assessing rental income potential when approving finance.

Legislative and tax changes can impact the profitability and compliance burden of owning multiple properties, especially if used for lettings in varying formats (holiday, corporate, long-term tenancy).

In summary, owning multiple homes in the UK means navigating increased council tax premiums, paying a 3% SDLT surcharge, complying with local regulations, and managing the tax implications on rental income and capital gains. Owners need to factor these into financial planning and seek advice to stay compliant and maximise investment value.
