  OH are very efficient and caring. They have been looking after my boiler since I moved to my present address. I cannot recommend them highly enough.

  Obviously a high end service. Initial response time was immediate. Advice and options explained extensively. All costing very transparent from the off. All invoices matched quotes, no surprises. 3 jobs all completed quickly even though Zak has a busy diary. Very happy tenants. Highly recommended, you get what you pay for, will be using again. 5 star.

  We have used Zak on several occasions and always found him reliable, polite, tidy and extremely knowledgeable. He has helped us out promptly with an emergency and is very fair with his pricing. We are really happy with the service he provides.

  Zak did an amazing job of both our bathroom and fixing and servicing our very old boiler. Wouldn’t hesitate to recommend him. He’s brilliant! Excellent quality of work and a really nice guy too.

  Optimum HVAC provided a very efficient service when my shower broke down. Zak Hurst provided this service. He was quick, efficient and polite and cleaned up after the job. I would recommend him to anyone.

  I've dealt with Zak for over 12 years and have always found him to be conscientious, meticulous with a very high standard of workmanship. He has recently completed the removal of an old bath and the installation of a new shower enclosure for me. I would definitely recommend him for any plumbing and heating projects you may have.
