Booking a national brand gets you a subcontractor. Booking us gets you an employed engineer in a Vantage van who was probably in the next street last week. We are in and out of Codicote, Knebworth, Woolmer Green most weeks as well, so Welwyn Garden City is not a place we visit twice a year.
It matters most when something needs a second visit, because a firm that lives in the area turns up and a firm that does not sends a different person and starts again.
Affinity Water’s own published figure for the Welwyn Garden City supply zone, zone code AF020, is a mean total hardness of 320 mg/l as calcium carbonate. That is hard water, and it is the reason we fit scale protection as standard on every installation here, regardless of which side of the railway line the property sits.
A service is not a look and a tick. The casing comes off, the burner and heat exchanger are inspected and cleaned, the seals and the flue are checked, and the gas rate and combustion are measured against what the manufacturer specifies. If the numbers are out, we say so and show you the reading.
Two things make servicing matter more here than the national averages suggest. And most boilers fail in the first properly cold week of the year, which is exactly when every engineer in the county is already booked.
Book in September or October and you get an appointment at sensible notice. Leave it until the heating will not fire in December and you are joining a queue. Landlords: we carry out the gas safety check and the service in the same visit, which is what we would normally suggest since the casing is already off.
An emergency is anything you cannot turn off, cannot live without, or cannot leave until Monday. A burst pipe, a cylinder overflowing into a ceiling, no heating in February with a baby in the house, a gas smell. Those get answered at any hour, and a person picks up rather than an answering service that calls you back in the morning.
The first thing we do on the phone is work out whether you should be turning something off before we arrive, and where your stopcock is likely to be. That two minute conversation has saved more Welwyn Garden City ceilings than anything we do afterwards. Then we tell you a realistic arrival time rather than a comforting one.
Vans carry the parts that fix the common failures on the first visit, so an isolation valve, a ballofix, a pump, a fan or a PCB does not become a second appointment. There is no call out fee in hours, and you are told what the work will cost before anyone starts. Out-of-hours attendance carries a £50 + VAT call-out, quoted on the phone before anyone sets off.
There is no call out fee in hours. An engineer comes, looks at the actual job, and gives you a price before anything starts. If you accept it, that is what you pay, and if the job turns out to be different from what was described on the phone we tell you before we carry on rather than afterwards.
A straightforward combi swap starts from £2,850 fitted, commissioned and registered. Everything else is quoted on the day, because a price list for repairs would be a work of fiction. What we will not do is give you a number over the phone and then find reasons to change it once the floor is up.
Every job carries a 2 year guarantee on our labour, separate from whatever the manufacturer gives you on the parts.
A person answers. You describe the problem, and we ask the two or three questions that decide whether this is an emergency, a same day job or something that can sensibly wait until a slot that suits you.
You get a realistic arrival window rather than a flattering one. The engineer who turns up is one of ours in one of our vans, not a subcontractor we found this morning, and he has the common parts with him.
You are told what is wrong, what the options are, and what each one costs, before anything is dismantled.
We run emergency cover 24 hours a day, 365 days a year, and for a genuine emergency in Welwyn Garden City you get a realistic arrival time on the call rather than a vague promise. Planned work is usually booked within a few days, sooner if we have a cancellation.
Once a year, and the manufacturer will normally require it to keep the warranty valid. Book it in autumn rather than waiting for the first cold week, when every engineer in the county is already committed.
It depends on the age, the part and whether the same fault keeps returning. We give you the cost of the repair against the cost of replacement and let you decide, and we will tell you when a repair is not worth doing rather than fitting an expensive part into an appliance that is finished.
Because clearing it treats the symptom. A blockage that returns usually means root ingress at an old joint, a section that has dropped and holds water, or fat build up. A camera survey tells you which, and only one of those is solved by rodding it again.
Not in hours. An engineer comes out, looks at the job and gives you a price before any work starts, and if you do not go ahead it has cost you nothing. Out of hours, meaning after 5pm, before 8am or at weekends, there is a £50 + VAT call-out, and we tell you that on the phone before anyone sets off.
Yes, registration 956889. You are entitled to ask any engineer for their card before they touch a gas appliance, and you should.

Call and speak to a person, any hour, any day of the year.

For anything that needs surveying, a bathroom or a suspected leak, we arrange a visit and confirm the price before work is booked. You are told the number before an engineer sets off.
Yes, and we tell you what it is on the phone before anyone leaves. Nothing gets added once we are at the door.
Same firm, same guarantee. Electrical work is certificated by a registered electrician who works with us.
