In short: yes, but there isn't just one, single rule to follow.
Legislative requirements for carbon monoxide alarms vary by which country of the UK your house is in and whether it is rented or owner-occupied. Most legislation requires at least one carbon monoxide alarm is fitted near new or replacement fuel-burning appliances (e.g. boiler, oven, fire place), specifically either 'tamper-proof' / 'sealed for life' alarms such as those using lithium batteries, or alternatively mains-powered models which are directly wired into mains supply as opposed to plug-in types. Some countries have exceptions for fuel-burning appliances used solely for cooking. Rented properties mostly require a CO alarm immediately even if no appliances are being installed or replaced.
