I am a British citizen living in France with my Russian wife who has a Carte de Séjour. We intend to visit the UK (together) soon. Have a look at the following link.
I would recommend writing to or calling UK Visas and Immigration to be sure.

As stated in Timatic, the database used by airlines:
Visa required, except for passengers with a "Family Member" Residence Card marked "Permanent Residence Card of a Family Member of a Union Citizen or Residence Card of a Family Member of a Union Citizen issued by another EEA Member State (but not Switzerland) to family members of an EEA national or national of Switzerland if traveling with or traveling to join the EEA national or national of Switzerland.
and
Visa required, except for passengers with a "Family Member" Residence Card marked "4EUFAM" issued by Ireland (Rep.) to family members of an EEA national or national of Switzerland if traveling with or traveling to join the EEA national or national of Switzerland.
So, if you hold one of those documents and are travelling with or to join your spouse, you do not need a visa. Otherwise, you do need a visa if you're a visa national
