Both jobs have been done to a high standard, they have been efficient, friendly and tidy. Would recommend!Posted on Simon RichardsTrustindex verifies that the original source of the review is Google. New combi boiler fitted by Danny from J Bagnall gas services . In the beginning by getting InTouch with the company via Lucy Bagnall then through Jim B giving me advice on which boiler would suit my needs to Danny fitting the boiler on a day of my choice , the whole process was done to a professional level and I would gladly recommend them to anyone seeking either a new boiler or servicing. Well worth a 5 star rating.Posted on Oliver SnellingsTrustindex verifies that the original source of the review is Google. Proper gent knows what hes doing.

Very pleased with standard of plumbing work and cost, will definitely use againPosted on David EdwardsTrustindex verifies that the original source of the review is Google. Dan is a hero. He didn't complain about the horrible working conditions (cramped, hot) in our loft. He replaced a leaky ball-valve quickly as part of an insurance call-out. We are happy.Posted on Robert BraunTrustindex verifies that the original source of the review is Google. Great experience from start to finish: Combi-boiler gave up on Sunday, Monday morning Jim came to have a quick look and advised of options, booked us in for a new boiler on Saturday but due to cancellation got it all sorted on Wednesday already. Job was done to high standard and the house was left all clean. Jim and his team are nice to deal with and have around. Many thanks!Posted on Paul MTrustindex verifies that the original source of the review is Google. Excellent service from Dan at this company. Sorted the issue quickly without any fuss.
