Some Businesses We Work With...




Posted on Rachel HampsonTrustindex verifies that the original source of the review is Google. Succeeded with my (vaillant) boiler and central heating system where other engineers have failed. Now enjoying properly warm house and hot water for the first time in several years in these colder months. Highly recommended.Posted on Vanessa ChapmanTrustindex verifies that the original source of the review is Google. Great Service in central London. Attention to detail and going above and beyond for a reasonable price. Rich did everything he could to work quickly and avoid additional charges, efficiently and effectively solving multiple problems (leaky boiler and gas leak) in one trip. He was well prepared, with all the materials he needed despite multiple surprises in the job. Ideal. This seems to be a family run business with genuine passion for the trade, so a good job done while supporting a decent small business. Highly recommend. Thanks for the help!Posted on Andrea TaylorTrustindex verifies that the original source of the review is Google. Posting on behalf of Hampstead Hill School. We had excellent communication with Rich from the beginning. He was punctual, professional, knowledgeable and managed to repair all of our issues within a busy environment. So on behalf of everyone at HHS thank you very much!Posted on Chris GreenTrustindex verifies that the original source of the review is Google. Rich has been servicing our 15-year old boiler for years, keeping it running smoothly, along with other general plumbing tasks as needed. Boiler recently developed a leak from a tiny crack in the supply manifold, creating an unwelcome new water feature in the kitchen.. Rich had the part identified, ordered and fitted within 24 hours. Always friendly and reliable, highly recommended!Posted on Mark WillingtonTrustindex verifies that the original source of the review is Google. Great service at short notice . Already booked my annual service for next year. Highly recommend.Posted on K PhizzleTrustindex verifies that the original source of the review is Google. Came out as soon as they could (first thing following morning) the repair turned out to be the cheapest of the 3 potential issues and the boiler was fixed and serviced in great time. Polite, professional and skilled.Posted on JohannaTrustindex verifies that the original source of the review is Google. Just what you want just before Christmas- a water leak in the house 🙀 All fixed though, thanks to the amazing Lewis Boiler Service from Clevedon (highly recommended). My daughter woke me at half midnight to tell me it was literally raining in her room. Lots of buckets and stress later but thankfully all fixed - they were amazing and it’s the second time I’ve called them in any emergency and the second time they have been there for us just when we needed them.Posted on Paul FarringdonTrustindex verifies that the original source of the review is Google. Fantastic! We woke up in the morning to find we had no hot water. I phoned Lewis Boilers to ask for a visit. They arrived a couple of hours later to have a look at the problem, I was expecting to be given a date when they could come to fix it. But the man immediately started working on it. After a thorough inspection he started to fix it. This was fantastic service, I wouldn’t hesitate to recommend them to anyone.Posted on brad smithTrustindex verifies that the original source of the review is Google. Lovely fella, worried about my boiler turning on and off in the middle of the night, came out the same day sorted it. Will be using richs services from now on.Posted on Louise WhitemanTrustindex verifies that the original source of the review is Google. Great service. Thanks for sorting our boiler out at short notice.
