What should you check before buying a flat above a shop?
Several things that do not arise with an ordinary flat — and they matter because the commercial use below affects mortgageability, insurance, resale and daily life, frequently more than the price discount compensates for.
Mortgageability, which is the first practical issue. Many lenders restrict or refuse lending on flats above commercial premises, and restrictions are tighter for certain uses — hot food takeaways, restaurants, pubs, bars, launderettes, dry cleaners, betting shops and anything with late hours. Some lenders decline outright, and a smaller lender pool affects both your purchase and every future buyer's, which is where the resale problem comes from.
Check what a lender's criteria actually say before offering, and note that criteria change.
Insurance. Buildings insurance is usually arranged by the freeholder, and premiums are higher where there is commercial use — particularly cooking. Contents insurance may also be affected.
The lease, which requires careful reading:
Service charge apportionment between residential and commercial parts, and whether it is fair.
Whether the commercial unit contributes to shared structure, roof and maintenance costs, and on what basis.
Access and shared entrances, including whether commercial deliveries or refuse pass residential areas.
Restrictions on what the commercial unit may become, since a bookshop today can be a takeaway tomorrow if the lease and planning permit it. This is the risk people miss entirely.
Practical living considerations: extraction odour and noise from food premises; delivery hours and refuse collection; pest risk, which is materially higher above food uses; late-night noise; and shared fire escape arrangements.
Fire safety, which is more complex with mixed use and has attracted increased scrutiny — including compartmentation between commercial and residential parts.
Who owns the freehold, which is frequently the commercial operator — creating an obvious tension where their interests differ from yours.
What to do: get the management pack early; ask the current owner what the commercial use is actually like; visit in the evening and at opening time; and factor a narrower resale market into the price you offer.
