2027 remortgage crunch: London landlords face higher rates, tougher lending and EPC upgrade bills

The immediate risk for many London landlords is not tenant demand but refinancing: a large tranche of buy-to-let mortgages is due to mature in 2027, and late movers could be pushed onto reversion rates while facing higher pricing, tighter affordability tests and awkward EPC-related costs.

Paragon Bank commercial director Simon Cockerill made the broad point in comments reported by Property Reporter. No verified London-specific maturity figure was published, so the sensible response is not to repeat a headline number but to work from your own portfolio data. If you fixed in 2022 for five years, or in 2025 for two, the refinancing window is closer than it looks once broker, valuation and legal lead times are factored in.

Why this matters more in London

In London, remortgaging is rarely just a rate question. Older housing stock, leasehold complications, service charges and EPC constraints can all reduce lender choice.

One property may refinance cleanly at a conservative loan-to-value while another in the same portfolio attracts fewer options because of a short lease, a weaker EPC, a non-standard tenancy or building-specific issues. That is why landlords need an asset-by-asset review, not a portfolio average.

Build a mortgage maturity schedule now

Create a schedule for every property and borrowing line. For each loan, record:

• lender
• current rate
• fixed-rate end date
• early repayment charge period
• outstanding balance
• current rent
• estimated current value
• ownership structure
• EPC rating
• any feature likely to affect lender appetite, such as a short lease or unusual tenancy arrangement

If you own some properties personally and others through a company, separate them. Criteria, pricing and legal requirements often differ.

EPC rules: separate law from politics

The current minimum standard for most privately rented homes in England remains EPC E, subject to valid exemptions. A move to EPC C has been proposed, but it is not yet law.

That distinction matters. Landlords should not budget on the assumption that a proposed deadline is fixed. But they should not ignore the issue either. Even without a legal change, lower-rated properties may be costlier to improve, less attractive to some lenders and harder to refinance smoothly if standards tighten later.

Why EPC upgrade costs can bite harder in London

London properties are often more expensive and more awkward to improve. Period conversions, solid-wall homes and ex-local authority flats can all create problems around insulation, glazing, communal heating or leaseholder consent.

If an EPC is several years old, get an updated assessment and real quotes rather than relying on an old certificate or national averages. The key question is not just the current band, but the realistic cost and disruption involved in moving a property from D to C if needed.

Choose the mortgage around the business plan

Some landlords will prefer a shorter fix or tracker because they expect to sell, refurbish or refinance again within the next two years. Others will want the certainty of a longer fixed rate.

The mistake is choosing solely on headline pricing. Model the numbers at least 1 to 2 percentage points above the rate currently offered, then test the result against the true net rental position after management fees, service charges, insurance, maintenance and likely voids.

Plan the exit before taking refurbishment or bridging finance

Landlords buying tired stock or funding works should treat the bridge, refurbishment budget and long-term remortgage as one decision. If the exit depends on an optimistic valuation, an unevidenced rent or works finishing perfectly on time, the funding plan is weak.

Before proceeding, check:

• realistic build costs
• expected void period
• likely value after works
• whether term lenders will accept the finished property
• whether the final rent supports the refinance case

Smaller landlords often assume a bridge can always be refinanced later. That assumption becomes expensive when costs overrun or the lender pool shrinks.

Limited company restructuring needs advice first

Buying through a special purpose vehicle may suit some landlords, particularly for new acquisitions, but transferring existing property into a company is a tax and legal decision before it is a mortgage decision.

A transfer can trigger SDLT, CGT, refinancing costs, lender consent issues and personal guarantee requirements. For some portfolio landlords the structure works well. For others, especially where exit planning or profit extraction matters, the costs can outweigh the benefit. Get written tax and legal advice before restructuring.

Three steps to take now

1. Build a portfolio schedule covering every mortgage end date through 2027, including ERC periods, EPC ratings and known refinance risks.
2. Stress-test each property for higher borrowing costs and identify any asset likely to need lease, EPC or capital works before remortgage.
3. Speak to your broker and current lenders early about refinance routes, further advances and whether any planned works should be funded as part of one joined-up strategy.
