Anisa Arif · Google, 9 months ago · excerptmy boiler went of today! No hot water no heating! I have 3 kids and needed this sorting asap as it is absolutely freezing! I rang saeed told him the problem, I called him at 8.30pm and he told me he would be here by 10.30pm…
Lee Reeves · Google, 7 months agoVery grateful to Saeed, who did a great job. We had no hot water and thought the boiler was faulty, and he came out within hours. He was quick, helpful, and clearly knowledgeable, explaining what was going on and giving advice on what to do if anything goes wrong in the future. Highly recommended.
Kiran Mahay · Google, 4 months agoExcellent service. Highly recommended. Came to repair a gas leak at short notice and explained the whole process. Excellent communication by text and on the phone. I would book again if needed.
Haseena · Google, 5 months agoHeating and Hot Water not working. Saeed came out on the same day diagnosed the issue and provided advice to the tenants. While he was there he also replaced a leaking pipe. Excellent customer service I would definitely recommend and use again.
Sam Crabtree · Google, 8 months agoSaeed did a fantastic job for us fitting a smart thermostat. I would say he went above and beyond in explaining the feature and how to use the thermostat despite me purchasing through a third party. Saeed was also super friendly and he would be my first choice for any other boiler work.
I Kanbour · Google, 11 months agoSaeed from Synergy gas and plumbing was excellent – he sorted the plumbing and did the gas servicing before my washing machine install. Professional, tidy, and very reliable. Highly recommend!
