Real call-outs

Questions from jobs like this

These come from real call-outs. See the full FAQs for more boiler and heating answers.

Why has my boiler broken down and stopped working completely?

The most common causes we find are a faulty PCB (the boiler's control board), a failed gas valve, or worn spark electrodes that stop ignition from working. On a call-out we diagnose the fault first, then talk you through the repair and cost before doing any work — no surprise bills.

My boiler keeps losing pressure — why does this keep happening?

Repeated pressure loss is usually down to a failed expansion vessel or a worn pressure relief valve (PRV). We recharge or replace the vessel, fit a new PRV where needed, and repressurise the system so it holds steady rather than dropping again within days.

My radiators and hot water stopped working after a power cut — is that connected?

Yes, this is a common one. A power cut can trip the boiler's electronics or knock out a component like a fan or PCB that was already close to failing. We diagnose, source the part, and get heating and hot water back on the same visit wherever possible.

I've got no heating or no hot water (but not both) — could it be a valve?

Very often, yes. Most systems use a motorised valve — either a 2-port zone valve or a 3-port valve — to direct hot water from the boiler to either your radiators or your hot water cylinder, depending on what's calling for heat. If that valve's motor or internal mechanism fails, it can get stuck sending water to only one side, leaving you with heating but no hot water, or hot water but cold radiators. We test the valve's motor and internal switching, and in most cases a straightforward valve replacement resolves it completely.

My heating works but my hot water doesn't (or vice versa) — what's wrong?

This usually points to a specific component rather than the whole boiler — commonly a diverter valve, flow sensor, or in system boilers, the cylinder's own controls. We isolate exactly which part is at fault before quoting, so you're not paying to replace things that don't need it.

Will I get a fixed price before any work starts?

Yes. Once we've diagnosed the fault, we give you a fixed price for the repair before doing any further work — not an estimate that changes once the job's underway. If we find something unexpected once we're inside the system, we'll always explain it and get your agreement before proceeding.

 Trustindex verifies that the original source of the review is Google. Had tried to arrange a simple gas safety check & boiler service on our onward property purchase which is time sensitive, given we are due to exchange this Friday. He knew this was time sensitive and ignored our messages for about 5 days before confirming a date. Richard was due to arrive today at 1pm and he just didn’t show up. Tried to call him multiple times to no avail, he’s just gone off the radar. When I finally got through to him and asked where he was, he replied “Oh I forgot”… Messaged him and expressed my disappointment and he just replied “ok”. He clearly never had any intention to carry out this job and has now jeopardised our planned exchange of this Friday as the boiler checks was the last thing to be completed. Am having to scramble now to find another plumber who can do same day as we need to proceed with our sale. Absolutely ridiculous. Terrible service, awful communication, I don’t know how Richard has positive reviews on here. Thank god I hadn’t paid anything in advance. Complete joke

 Trustindex verifies that the original source of the review is Google. I had a really great experience with Richard at Talis when he repaired my hot water cylinder today in Egham. From the start, he was courteous, friendly, and very quick to respond to my enquiry. He arrived promptly, completed the job efficiently, and clearly knew what he was doing. Everything was handled smoothly and with minimal disruption. The pricing was very reasonable and fair, which was a pleasant surprise. Overall, I’m extremely happy with the service and wouldn’t hesitate to use him again or recommend him to others. 5 Stars

 Trustindex verifies that the original source of the review is Google. Resolved our initial issue but left us with a leaking condenser pipe and disconnected the control panel & heating and hot water stats because he didn't like the electrics, without discussing this with us first. To be clear, the wiring had always been a bit confusing but having had it that way for 18 years and knowing how it worked, it wasn't something we had envisaged doing, especially without any prior conversation about it.

No costs of materials were given up front despite me saying several times that we didn't know what he was doing or what the costs would be.

Richard then gave various excuses for not returning when he said he would,  including taking a day off, putting his back out, parts not arriving on time (several times) & finishing other jobs.
He also repeatedly ignored messages and at one point suggested we got someone else in to finish the job, so he clearly just didn't want this job.
16 days after he first started, he eventually returned but didn't finish job properly. The new control panel was fitted, electrics were sorted to what he wanted, and a WiFi controller was installed despite us never having discussed or agreed it. The hot water cylinder stat was replaced but the sensor was not attached properly to the cylinder.

Richard's response when I sent him a photo of the mess he left and a message noting the backing paper was still on the metal film, he said he used what was supplied in the box to attach the sensor to the hot water cylinder, as per the instructions. However Richard didnt actually clean the cylinder or remove the backing paper from the foil so the sensor fell off within a couple of hours and has continued to do so ever since.
The heating system now works, the hot water cylinder doesn't because he didn't secure the sensor properly.
He said he would return to fix it but only once the £1150 invoice had been paid in full.

He has since sent a thermostat and strap for US to attach to the hot water cylinder ourselves, or get someone else in to finish his job, at our expense again.

The job cost us £1150 which included him making and taking multiple phonecalls to other clients, colleagues and the company of the parts he bought to find out how to install them?!?!

At once point in conversation he mentioned someone in Paddington who was trying to dispute his work/charges - that should have set alarm bells off, but I trusted him based on his Checkatrade reviews.  Incidentally I have been unable to leave him a review on Checkatrade so be careful when you hire via there.

My take-aways: Lack of professional conduct, unreliable, expensive and not undertaking services with due care and attention.

Richard 'kindly' discounted his rates from £120/hr +VAT to £100 hour +VAT, (we did not ask for this but maybe there was a little bit of guilt felt?!) but he left us with so much frustration at his poor communication and lack of transparency from the outset that it was the least he could have done. The parts he provided cost in excess of £500 plus VAT, with no prior warning!

In the end he twisted so much of what happened to make it sound like he was accommodating and did everything perfectly. He did not.

I lost a client, cancelled a hospital appointment and waited home for him multiple times but he was so unreliable. I told him all of this and he couldn't care less.

It seems he does some excellent work most of the time, some certain people, but if he's not interested, be warned, you'll get a shock.

 Trustindex verifies that the original source of the review is Google. Richard Sammon from Talis Heating Solutions came within 60’ to fix in urgency my water pump which burnt out. Based on the picture I sent he found a replacement pump, even though it was already 07:30pm and fixed the issue in an hour. He saved the day!! Highly recommend.

 Trustindex verifies that the original source of the review is Google. Great, quick service when our boiler wasn't switching to heating mode , and a call out fee that was reasonable considering the distance (Middlesex to near Reading!)
