Central Heating- 23 Dec 2020
Fred was extremely polite, prompt and reliable. He replaced a broken hot water controller and bedroom heater with a very short notice for my tenants. Although I was abroad at the time trying to communicate over messages and whatsapp he made the whole process very smooth by updating me every step of the way. Having had a very bad experience with another electrician previously which made my job more complicated and was very rude I can highly recommend Fred in particular for his professionalism.

Gas Work- 30 Oct 2025
After extensive discussions and receiving a formal quotation, which I accepted, the contractor assured me he would provide a materials list — this was never sent. When the agreed start date arrived, he failed to attend and ignored all messages and follow-up attempts. This type of behaviour is completely unacceptable and shows a total lack of professionalism, reliability, and respect for clients. I even explained that my family-run business was closed and that the work needed to be completed urgently, yet he still failed to show up or communicate. Just imagine if he had started the work and then decided the next day not to turn up — the consequences would have been disastrous. Avoid this individual entirely — he cannot be trusted to honour his commitments or conduct himself in a professional manner.

Central Heating- 13 Apr 2026
Disappointing customer experience Requested new boiler installation with 10-year warranty. The total cost of work was £2,638. A Pulsacoil unit was recommended and ordered by the Plumber. Delivery took three weeks; installation took two days. Prior to installation, I requested confirmation of a 10-year warranty on multiple occasions (via the MyBuilder job description, email, and in person). After installation and registration of the boiler, I was informed that the unit supplied only had a 5-year manufacturers warranty. At no point prior to order/installation was I informed the boiler they had ordered only had a five year warranty. To obtain a 10-year warranty, an extended warranty (quoted at £635 via Pulsacoil) is required. The plumber verbally agreed to cover this cost and advised documentation would follow. Six weeks later, still no written confirmation of the extended warranty. Recommend customers independently verify warranty with the manufacturer before proceeding with this company

Tiling- 1 Sep 2020
**HIGHLY NOT RECOMMENDED** I have not seen such an unprofessional service provider in my entire life. His guys lack the basic skills of tiling and created a mess of my new home. Issues: 1. They spill water in my bedroom with carpet and in lobby with wooden flooring which got damage 2. Whole house was filled with tile dust, 3. the tiles were not cleaned 4. tiles waste a separate issue 5. my balcony looked like a garbage room 6. cement marks on walls, ceiling and walls needs a paint work 7. to my utter disgust they left tiles pieces in my toilet. 8. Also the tiles are so poorly installed that I think I was better off without them. I wish there was an option to upload the pictures so people could understand my pain. Upon giving him calls to see the mess created by his guys he was reluctant at 1st to come and said he is tired & cant come. On sharing pics, he decided to show up & promised to clean the mess & complete the task. But after 2 weeks of struggle his guys shows up 3 times for 2-3 hour each. But today he finally decided to quit without doing his job. Now I need to find a new Contractor to complete the work. Also, He promised that he does quality work, to start when he visited and quoted me a price and said that he would send the quotation on mybuilder and thats how it works. He sent quotation 3 days later with 65% increase in price and later negotiated to 30% higher than original

Jamie was quick getting back to me initially and came round to quote for the job shortly afterwards. He was very accomodating when working out a suitable time to do the job that fitted around my schedule. He explained everything, presented different options and gave advice about how to complete the job. His work was excellent, I would have no issues hiring him again for more work in the future.
