My boiler broke in spite of a recent service and safety inspection. Bad enough, but not what you want in the winter. Charlie came the same day, didn’t charge emergency call out fees, and confirmed that last safety inspection was inadequate. The next day he came early and fitted a new boiler. I can recommend Charlie - he’ll clearly communicate the options, do a thorough job, focus on safety and charge a fair price.

Andre and team did a great job with the shed /summerhouse construction, and were very accommodating with the request to build it at short notice ( (within 5 days) and alter the layout of the building to meet our requirements. Also were very friendly and professional. Reasonably priced too. Would recommend.

Petre and his team were exceptional. He was able to complete the entire job including plumbing, complex fitting of worktops and three sided breakfast bar, splashbacks and hardwire electric installation in just three days and to a brilliant standard. The company is super responsive to emails and nothing is too much trouble. They are great at problem solving and the finish is first rate. Polite, tidy, skilled, talented and efficient, he double checked every detail with me so we got what we wanted. Delighted.

We are delighted with Tim’s excellent and professional service in fitting a replacement radiator and clearing a problem drain for my elderly mum. He responded straight away with his quote and I found him very reassuring when he explained on the phone how he would carry out the job and how he was able to complete the job within a week, which was perfect timing for us. He was friendly, efficient and completed the job to a high standard. We are very happy and would thoroughly recommend without hesitation.

A guy called Michael showed up, gave it all the large talk about what he would do. Gave him an address for another project also out of goodwill so he didn’t have to buy another lead. Promised to get back to me despite promising me he would return that week to do the work. Instead just ignored every phone call and message. He kept mentioning about wanting to do it in the evening…. This was impossible as it was a shopfront. Absolutely no balls, AVOID LIKE THE PLAGUE!
