Verified by CheckatradeNew boiler and radiator plus solved airlock issue

Marc did a fantastic job for us - he installed a new boiler and radiator as well as sorting out an airlock we had in our system. We've used Marc a number of times in the past and each time he has been responsive, easy to deal with and reliable. His work is to a high standard and he leaves the area tidy. Will definately be using him again in the future.

Marc managed to fit me in on the same day I called. Great that he can be so flexible. As always he was professional, on time, upfront on the cost. He treats you and your property with respect and goes through the detail with you. No hesitation in recommending him.

Verified by CheckatradeMultiple Radiator replacement and relocation

Will certainly be using again! At extremely short notice Marc was able to move and re-plumb multiple radiators after an urgent request was made in order to get the rooms ready in our new house before we had new flooring laid. Polite, honest, reliable and very reasonable are words I would use to describe the service we received. Marc’s genuine knowledge and passion for his profession shone through and also his kindness and care to go above and beyond (taking the time to explain how to use our new heating system in detail to help out is one example). I would highly recommend. Thank you so much!

Verified by CheckatradeGas boiler and thermostat not working

I booked in for an engineer to visit he arrive as agreed. Marc identified the problem and immediately sourced the part, went to the shop and came back and fitted it. The boiler was working. As agreed he came back the following week and installed the new thermostat. I would have no hesitation using them again.

Totally reliable, very honest about costs and transparent about material costs. Highly recommended and have done to all my family, friends & neighbors. Nothing is too much trouble and refreshingly honest recommendations about repair or replacement.

Marc was so helpful when we found ourselves with no heating or hot water. He ordered the part and fitted it as quickly as possible. He was very clear on the costs and charged as quoted. Would absolutely recommend. Thank you

What to check before you hire

Worth checking yourself
Always confirm credentials and quotes with the business directly before hiring.
Verify at the sourceCheck them yourself

Electrical work in homes in England & Wales should be done by a registered competent person who can self-certify it meets the Part P safety rules. Check they're on the official register.

Check the electrical register
In England and Wales, notifiable electrical work (new circuits, a consumer unit, anything in a bathroom or kitchen) must by law be signed off under Part P of the Building Regulations. Confirm they will handle that.
Prefer an electrician registered with a government-approved competent-person scheme (NICEIC, NAPIT or ELECSA) so they can self-certify the work meets the wiring regulations.
Insist on the Electrical Installation Certificate (or Minor Works Certificate) when the job is done. It is your proof the work is safe and compliant, and you will need it if you ever sell.
