Knows his stuff, wouldn't hesitate to recommend!
Would definately recommend. Came out and fixed my boiler the same day.
Courteous, efficient, nothing is too much trouble. Good workmanship, always leaves the site clean and tidy.
First class service from Marshall Heating, thoroughly recommended! Helped me save a bundle on the replacement part needed for my heating system and charged half what British Gas quoted to install my new Hive thermostat. Worked late into the evening to get the job done by the deadline I'd asked for. Great service.
I originally met Lee prior to him setting up his own business and am pleased to say that the service he provides is still excellent. He is helpful and goes out of his way to ensure the work is done and it's reassuring to find a tradesman I trust and know will do the job well.
Excellent, high quality workmanship, advice and professionalism. Very pleased.
The work of replacing a CH pump, also locating and curing a gas leak was carried out when promised in an efficient manner.
Always willing to carry out extras.
Put my mind at rest as he has gas safe ect. Good sound advice. Recommend him.
I have know Lee from when he worked with Stephen Hatfield Gas Services so had no hesitation in using him now he has his own company. Lee is very knowledgable, thorough and always takes time to answer any questions you may have, as well as always being puntual and tidy. He did have a good teacher after all. I would not hesitate in using him again and would definately recommend him. Thanks for a great job
As in previous years, they provided a competent and friendly service.
Very efficient, polite and young man. Will recommend him.
The work carried out by Lee Marshall was of excellent quality. i am very happy to have him as a heating engineer.

Smart checks
Before you hire a plumber
Agree the call-out fee, the hourly or fixed rate, and whether parts are charged on top — in writing — before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints.
Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced — get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work.
Gas and boiler work is a separate, regulated trade — not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start.
Look for consistent reviews across several named sources, not one polished profile.
Check any verified credentials, and that the business details independently check out.
