## One utility for MUFB mortgage

Some MUFB mortgage lenders require each flat within a Multi-Unit Freehold Block (MUFB) to have separate utilities, such as individual gas, electricity, and water meters. This requirement is often linked to the lender’s risk assessment and how the property is valued. Blocks of flats that share a single utility supply can still be financed, but they usually require specialist mortgage advice from expert brokers like Mortgage Lane. We work with lenders who have flexible criteria and can provide MUFB investment mortgages for properties with shared utilities, ensuring that investors can still access competitive products and funding solutions.

When a block of flats has shared utilities, the mortgage is typically assessed using a block valuation. Unlike an aggregate valuation, which values each unit separately, a block valuation treats the property as a single investment asset. This approach can impact the property’s overall valuation and, in turn, borrowing capacity. Since the resale market for such a property is narrower-appealing mainly to other investors rather than individual buyers-the valuation may be lower compared to a building where each flat has separate utilities. This can also influence the best MUFB mortgage rates available, as lenders price according to perceived risk and re-saleability.

The difference between shared utilities and separate utilities has a notable impact on both financing and resale strategy. Properties with separate utilities are generally considered more flexible and desirable. They can be sold as individual units, which opens the property to the retail buyer market, often achieving higher aggregate sale prices. Conversely, blocks with one utility are typically restricted to block sales, which are valued based on rental yields rather than individual market values. This difference can lead to a lower sale price, as any future buyer will likely factor in the cost and complexity of installing separate meters or splitting titles.

From a practical standpoint, a single shared utility requires the landlord to manage cost recovery through service charges or all-inclusive rents, which adds administrative work and financial risk if tenants fail to pay their share. Retrofitting separate meters later can be expensive and disruptive, often involving rewiring, plumbing changes, and updates to leases. This also affects refinancing potential, as the property will likely continue to be subject to block valuation terms rather than being eligible for products based on individual unit valuations.

Despite these challenges, there are situations where shared utilities are acceptable or even advantageous, such as student housing or serviced apartment blocks where “all bills included” is a standard model. In these cases, Mortgage Lane works closely with specialist MUFB mortgage lenders that are comfortable with this setup. We ensure that the property’s income structure, tenancy terms, and management systems are presented effectively to secure the most suitable finance, even if the rates are slightly higher than standard MUFB mortgage rates.
