What we do

What people say
Based on 240 reviews
Boiler packed in on a Friday night with two young kids in the house. Someone was out first thing Saturday and it was sorted by lunchtime. Cannot fault them.
Sarah · Llanishen
Gave me two options, explained both, and did not push me toward the expensive one. Turned up when they said they would and left the place spotless.
Dai · Whitchurch
Been servicing our boiler for six years now. Same lads every time, always polite, always on time. Would not use anyone else.

Common questions
For no heating or no hot water we aim for same day, and we hold slots back each morning for emergencies. If we genuinely cannot get to you we will say so on the phone rather than leave you waiting in.
No. There is no callout fee. You pay for the work, and we agree that price with you before anything starts.
Sometimes yes, sometimes no. As a rough guide, once a boiler is past twelve years old and the repair is heading toward a few hundred pounds, you are usually better putting that money toward a new one. We will tell you honestly which side of the line you are on.
Yes, every one, and they all carry their card. You are entitled to ask to see it, and you should, with anybody who works on your gas.
We do, and we can arrange access directly with your tenants if that is easier. The certificate is emailed over the same day the check is done.
About us
Ellis & Son started in 1998 with one van and one engineer. Nearly thirty years later we are still small enough that you will speak to the person doing the work, and most of our jobs still come from somebody recommending us to a neighbour.
Registered, fully insured, and everything we fit is guaranteed.
Give us a ring and we will tell you straight away whether we can get to you.
