The usual excellent high quality friendly service for the annual boiler service - excellent advice and discussion for future services and actions on the boiler and the heating and hot water system.

Elementis came out to do a stripdown full boiler service on my central heating having done a routine annual service for the last couple of years. It was easy to book an appointment online and I was contacted to verify the make of the boiler to ensure they had the right gaskets. They arrived on time and did the job with minimal disturbance and no mess; everything was thoroughly checked over before they left. Always polite and friendly and take genuine pride in their work, will continue to use and recommend.

Grant took time to explain what he would need to do in the installation. Kept us informed when he would be arriving which was a great touch. He spotted an issue in our loft that could have been disastrous if not had been fixed, he even helped us rectify the problem. I would recommend Grant to others to install a new boiler and complete heating solutions. We will be using again for future services and any advice we require.

Grant arrived when he said he would having notified me shortly before of his expected time of arrival. He carried out the annual boiler service efficiently and explained to me clearly what he was doing. He then inspected my hot water tank as I had asked him to do when I booked him. Again, he explained how it worked since I had not seen the type of system before. In addition, he checked that the system was pressurised correctly and also checked that the central heating system was working properly. I was impressed with his approach and quality of work and I will certainly have him back next year to carry out the annual boiler service and check on the hot water tank.

Boiler service & replacement
Customer Service

Great experience from start to finish, requested for an annual boiler service, aware my boiler was old, advised it was emitting gas and capped, as unsafe. Unfortunately the valve needed for replacement was obsolete. Confirmed with the boiler manufacturer this was case and quoted approx £3250. Checked against other companies including British Gas who did a free assessement. BG wanted £9000 for the boiler removal and replacement to combi boiler for the same quote. Elementis did everything they said they would from start to finish. System was flushed, new flue etc. Fast turn around within a week of the boiler service too! Would absolutely use again, restored trust in the world of tradespeople! And nice to support a family business!

Just had a new boiler and rads installed by Elementis. Grant was an absolute pleasure to deal with from the outset. Their quote was competitive and communication was faultless, even responding on a Sunday! Punctual, clean and tidy. Relax you're in safe hands, Grant knows his stuff.
