As the Chancellor prepares to deliver the Autumn Budget 2026, high-net-worth (HNW) individuals face evolving fiscal challenges. With persistent economic pressures and public sector borrowing constraints, HNW clients must look beyond broad headline tax changes.
Protecting wealth, structuring debt, and ensuring seamless legacy planning require proactive measures before potential reforms take effect.
At Liddle Perrett, we closely monitor these developments to help our clients navigate potential policy shifts in the Autumn Budget 2026. Below is an overview of the key risk areas to review ahead of the fiscal announcement across mortgages, equity release, protection, and estate planning.
Prime Mortgages & Refinancing Ahead of the Autumn Budget 2026
Table of Contents
While interest rates remain a central focus, high-value mortgage borrowers face distinct structural considerations:
- Affordability & Corporate Income: Proposed adjustments (not confirmed policy; details may change) to dividend taxation, profit extraction, or property surcharges could tighten lender affordability assessments, particularly for clients drawing income through Family Investment Companies (FICs) or complex trading structures.
- Liquidity & Asset Disposals: ‘There has been speculation about Capital Gains Tax (CGT) reforms, making selling physical property assets to reduce leverage less attractive. Of course, any future changes are subject to government consultation and may differ from what is currently being discussed. HNW clients may wish to review their options such as interest-only facilities, asset-backed lending or fixed-rate refinances to retain liquidity without triggering premature tax liabilities.
Most Buy-to-Let Mortgages are not regulated by the Financial Conduct Authority. Commercial mortgages are referred to a third party. Neither Liddle Perrett Ltd nor PRIMIS are responsible for the service received. These services are not regulated by the Financial Conduct Authority and may have limited consumer protection.
Your home or property may be repossessed if you do not keep up repayments on your mortgage or any other debt secured on it.

Strategic Equity Release & Lifetime Mortgages
Equity release is increasingly used by affluent homeowners as part of holistic tax and cash-flow management rather than purely out of capital need:
- IHT and Pre-Emptive Gifting: ‘Unlocking equity can support lifetime gifting strategies, which may help reduce the value of your estate for inheritance tax purposes. Gifting rules are complex – gifts must meet specific conditions, and there is a 7-year rule. We recommend you seek professional tax advice.
- Managing Accumulation Risks: With interest rates remaining above historical lows, compound interest can erode property equity faster than expected. Hybrid structures or interest-servicing options may help preserve the underlying property value for future generations.
Equity release / Lifetime mortgages will reduce the value of your estate and may affect your entitlement to state benefits.
Mortgage Protection & High-Value Life Cover
Structuring adequate protection becomes critical when fiscal tightening increases an estate’s overall liabilities:
- Covering Expanding Net Liabilities: As tax exemptions compress and asset values grow, the net liquidity required to discharge mortgage debt upon death increases. High-value mortgage protection ensures debt obligations do not force a distressed sale of family assets by surviving heirs.
- Preserving Benefits via Trusts: Ensuring life policies are correctly written in trust remains essential. When set up correctly, policies written in trust can help ensure payout proceeds pass directly to beneficiaries, reducing delays and IHT exposure.
Estate & Succession Planning
Estate planning remains a central pillar under regulatory focus, with key areas requiring attention ahead of the Autumn Budget 2026 legislative updates. Any actual changes following the Autumn Budget 2026 will be confirmed by HM Treasury:
- Relief Caps & Threshold Freezes: Freezes on the IHT Nil Rate Band (£325,000) and Residence Nil Rate Band continue to push wealth into taxable territory through fiscal drag. Furthermore, capped reliefs for Business Property Relief (BPR) and Agricultural Property Relief (APR) necessitate an immediate review of commercial and land holdings.
- Pensions & Offshore Considerations: With unused pension funds coming into the IHT regime, and ongoing shifts affecting global and non-domiciled individuals, traditional succession strategies require updating. Families may wish to re-evaluate drawdown timing, lifetime gifting schedules, and trust arrangements.
Estate planning services, including trusts, wills, tax planning, and legal advice, are not regulated by the Financial Conduct Authority. Where estate planning services are required, Liddle Perrett will refer you to a specialist, independent third-party provider.
Proactive Steps for HNW Clients in Autumn Budget 2026 Planning
- Review Current Mortgage Facilities: Audit existing interest rates, facility end dates, and cross-collateral structures.
- Audit Estate & Corporate Structures: Re-examine wills, corporate property holdings, and gifting histories to align with anticipated tax boundaries.
- Assess Policy Ownership: Confirm all life and mortgage protection policies are properly held in trust.
- Consult Your Advisory Team: Wealth preservation relies on co-ordinated advice across legal, tax, and mortgage specialists.
Frequently Asked Questions: Autumn Budget 2026
Below is a summary of measures that were widely rumoured ahead of previous fiscal announcements but have not been implemented. Any changes announced in the Autumn Budget 2026 will be confirmed by HM Treasury.
Did the widely rumoured 8% National Insurance (NIC) levy on rental profits materialise?
No, the 8% NIC levy was not introduced. Instead, a 2% Property Income Tax surcharge applies across basic, higher, and additional tax bands starting April 2027.
Is a 1% annual "Mansion Tax" being imposed on high-value properties?
No, the 1% levy was not enacted. A High Value Council Tax Surcharge is introduced from April 2028 as a fixed annual fee (£2,500 for homes over £2m and £7,500 for homes over £5m).
Have Capital Gains Tax (CGT) rates on residential property increased?
CGT rates for residential property remain unchanged at 18% (basic) and 24% (higher), and Private Residence Relief remains uncapped.
Is transferring property into a Limited Company (SPV) still an effective strategy?
Generally, incorporating into an SPV may remain tax-efficient for some individuals, depending on personal circumstances. Section 24 restrictions remain in place for personal owners, and the new property income surcharge widens the gap between personal rates and Corporation Tax. However, this is not necessarily suitable for everyone. Please seek professional tax advice to assess whether this is appropriate for your situation.

Your home may be repossessed if you do not keep up repayments on your mortgage.
A Lifetime Mortgage will reduce the value of your estate and may affect your entitlement
to means-tested benefits and tax status. The impact of not servicing monthly interest payments on a Lifetime Mortgage is that the outstanding debt can grow rapidly, thus reducing the value of your estate. For example, if the interest rate was 7% a year, a £50,000 loan would double to £100,000 after 10 years, assuming no repayments are made. This is an example for illustrative purposes only and personalised advice and recommendations should be sought from a qualified professional.
