R S Boiler Services is described by several customers as a family-run firm that is polite, helpful and knowledgeable, with reviewers reporting boiler installations, servicing, radiator and heating repairs, a system flush, a water softener and tap fitting, and an air source heat pump system. One reviewer said the team changed their water system and solved flow and temperature problems throughout the home, and another said a new boiler and flush left old pipes and radiators working better and the house warm again. Reviewers also report that the firm responds promptly, turns up when it says it will, and has squeezed in emergency calls quickly. One customer described a poor boiler service: a leak and noise started the day after, later visits did not fix the noise, the pressure dumped over a freezing weekend, and emails were ignored for a week before a reply that the reviewer felt showed no empathy or accountability. That reviewer said Adam refused a refund and disputed the faults, while two Vaillant engineers reported unserviced parts and missed safety checklists.

I cannot recommend this company highly enough. I was in need of help with my heating and hot water after being given the wrong advice previously by others including British Gas. Adam and his team came highly recommended to me by a neighbour and I was fortunate that he was able to find time to help me. They changed my water system which alleviated all my issues with flow and temperature throughout my home. They were friendly, polite and professional and nothing was too much trouble. Adam ensured that everything was done to perfection, even if it involved staying on to complete the tasks in a professional manner. Thanks to Adam, Justin and Gabriel. All fantastic!

We've been using RS Boilers for a number of years now and honestly couldn't recommend them highly enough. Our house is very old with a rather unusual heating and plumbing system which means we're forever dealing with plumbing and boiler issues but the team have always been incredibly patient, reliable and helpful. Whenever we've had an emergency, they've done everything they can to squeeze us in as quickly as possible which has been an absolute lifesaver. They're professional from start to finish, always honest and knowledgeable and nothing ever seems too much trouble. Fantastic service, genuinely lovely people and a family-owned company we completely trust - highly recommended.

Impressed by the professionalism of the boss, I asked this small, family run firm to supply and fit an external oil fired boiler. The firm did not disappoint. Far from it. In fact, the installers - Bobby, Darryl and Gabriel - proved an absolute delight, working fast, efficiently and cheerfully in spite of a ferocious heatwave. They finished the job on time, and at a reasonable price. I heartily recommend this company.

Another excellent service from Adam and his team. They arrive when they they say they are going to, the guys are polite and hard working and they get the job done in challenging circumstances. Thanks again RS!

Adam and the team at RS boilers Marlow, have been fantastic from start to finish. Our new boiler was installed with real care and skill and the full system flush has made such a difference; our old pipes and radiators are now working far more efficiently and the house feels warm and cosy again. They also fitted a new water softener and kitchen tap both done to a really high standard. We are absolutely delighted with the workmanship, professionalism and attention to detail, and can’t thank them enough. We would thoroughly recommend them.
