Find a boiler servicing engineer near you
If you want to get your boiler serviced you need to be sure that the central heating engineer who does the boiler servicing is properly accredited.Without accreditation, not only is the plumber not qualified to do the work - it's also illegal and your boiler may not be safe either.
One way to find a boiler servicing engineer and be sure about the fitness of your fitter is to look at the Gas Safe Register database of suitably qualified engineers and plumbers.
You can search for a plumber by area and see whether they are qualified to do boiler servicing or not.
Please bear in mind that the database also contains many firms who don't offer boiler servicing to the general public - companies like Housing Associations for example, who have their own in house plumbers to look after their tenants, still have to be registered on the Gas Safe Register.
