    Great service from a professional member of staff.

    Posted 17 February

    Sean did a radiator hot flush and updated all the radiator thermostats. I’ve recently been introduced to Carshalton Boilers and would highly recommend. Sean was polite, efficient and very professional. The work was carried out really well and he kept me updated as he progressed through the day. The end result was great and I am more than happy. I will continue to use them. Sean is a credit to the company.

    Done right first time.

    Posted 14 February

    From initial survey to installation, everything was exactly when promised. The installer(s) left the house clean and tidy at the end of each day and the instructions left with me were clear and easy to follow.

    Cleaning out the Central heating system.

    Posted 26 January

    Sean spent 5 days, upgrading our central heating system, which has been in place for 40 years. It was a big job as the system was full of sludge. Sean was well-organised and competent. He explained what he was doing and shared his progress. He was pleasant to have in the house and sensitive to our needs.

    excellent boiler company

    Posted 16 January

    Sean arrived yesterday to sort us out with radiators.. He was on time, courteous, helpful, efficient, knowledgeable and quickly solved all our problems. Carshalton Boilers are a great company, we have used them for many many years and, although this time we did have a problem, we had great service to put it right and visits from excellent employees. Plus the very helpful staff in the office!

    Excellent, friendly service

    Posted 11 December 2025

    We have had a servicing contract with Carshalton Boilers for many years and have always found them very helpful and reliable. Over the past four days, they have successfully completed the installation of a new boiler. Every aspect of the job was excellent. Jackie in the office scheduled the work as quickly as possible - even managing to bring the job forward by a week from the original date. Paul, the surveyor, gave us clear advice on our various options. And Sean, our installer, was a joy to have around - extremely efficient and at great pains to explain every stage in the process.
