Is buy-to-let regulated by the FCA?

The general rule

Standard buy-to-let mortgages are generally not regulated by the Financial Conduct Authority (FCA). The reasoning is that a deliberate investment purchase, made to let out for profit, is treated as commercial/business lending rather than a consumer credit product — so the strict FCA mortgage conduct rules that apply to residential mortgages don't automatically apply here.

That doesn't mean "anything goes" — lenders still follow their own underwriting standards and many voluntarily follow good-practice codes — but the statutory consumer protections are different from a residential mortgage.

What counts as "consumer buy-to-let"

There's an important exception carved out in UK mortgage regulation: consumer buy-to-let (CBTL). Broadly, this applies where the borrower did not enter into the transaction "wholly or predominantly" for business purposes — common examples include:

• someone who inherits a property with sitting tenants and decides to keep letting it rather than sell;
• someone who lets a property to a close family member (as defined in the regulations) rather than the open market;
• an "accidental landlord" — for example, someone who couldn't sell a former home and let it out instead, without originally intending to become a landlord.

Consumer buy-to-let lending and advice is regulated by the FCA, much closer to a residential mortgage. If your situation might fall into this category, say so early — it changes which firms can legally deal with you and what protections apply.

Why this matters to you

Two practical consequences:

1. Who can help you. A firm or individual doesn't need FCA mortgage authorisation to arrange most standard BTL lending, but they do need it to advise on or arrange consumer buy-to-let. If your case is CBTL and the person you're dealing with isn't authorised for it, that's a red flag.
2. What protection you have. Regulated activity brings FCA conduct rules and access to the Financial Ombudsman Service if something goes wrong. Unregulated standard BTL lending generally doesn't carry the same statutory route, though individual lenders may still have their own complaints processes.

How to check a broker or adviser

Search the firm and the individual adviser's name on the FCA Financial Services Register. Check that their listed permissions actually cover what they're doing for you (e.g. "regulated mortgage contracts" and, if relevant, consumer buy-to-let), and be wary of anyone who's reluctant to confirm their FCA status or Firm Reference Number (FRN).

FAQ

If BTL isn't regulated, does that mean it's riskier?

Not necessarily riskier, but the statutory safety net is different. Established lenders still underwrite carefully and compete on service — but you personally carry more responsibility for doing your own due diligence, which is exactly why resources like the FCA Register and impartial guidance from MoneyHelper are worth using.

Can an unregulated BTL lender still be legitimate?

Yes — most mainstream buy-to-let lending in the UK, including from well-known banks and specialist lenders, is unregulated precisely because it's treated as business lending, not because the lender is doing anything unusual.
