Service Overview

What a heating engineer actually does for your home

A heating engineer looks after the whole system that heats your home and your hot water: the boiler, the gas supply to it, the pump and valves, the pipework, the radiators, the cylinder if you have one, and the controls that tie them together. A plumber can change a tap. Only a Gas Safe registered engineer is legally permitted to work on the gas side of your boiler, and only an engineer who understands the whole system will spot that your "broken boiler" is actually a seized diverter valve, a clogged heat exchanger, or a system full of sludge that has been quietly killing pumps for years.

CSGHP Ltd is Chris Smith's business, set up in 2019 after an apprenticeship at British Gas and years with E.ON and Vaillant, 23 years in the trade since 2003. That background matters on the day: manufacturer training means faults get identified from the symptoms rather than by swapping parts one at a time at your expense.

We work on domestic properties only. That is a deliberate choice. Homes, landlords and letting agents across Nottinghamshire and Derbyshire get an engineer whose day is not being interrupted by commercial plant work, which is why a same or next-day response is realistic for most breakdowns inside our opening hours.

Every visit starts with a fixed, known cost. A diagnostic call-out is £80 + VAT and includes the first hour on site. If the repair needs more than that hour, you are given a price and you decide before we carry on. There is no open-ended hourly meter running while you wait in the kitchen.

Who this is for

Homeowners with a fault nobody has explained

Cold radiators, no hot water, pressure that keeps dropping, a boiler that locks out every few days. You want the cause named, not another temporary reset.

Landlords and letting agents

You need a CP12 gas safety certificate, any remedial work quoted in writing first, and an engineer who deals with tenants politely and turns up when promised.

Households planning ahead

Your boiler is old but still running and you would rather replace it in September on a fixed quote than in January in an emergency.

People caring for elderly relatives

Our reviews repeatedly mention patience and care with elderly and vulnerable customers, including a customer living with dementia. Heating work in someone's home is not just technical.

Leave It and It Gets Worse

What happens when heating faults are left to run on

Heating problems almost never stay the same size. A small leak on a radiator valve drops system pressure, so the boiler tops itself up or gets topped up manually, and every top-up brings fresh oxygenated water into the system, which accelerates internal corrosion. The black sludge that produces then blocks the bottom of radiators, strains the pump, and eventually restricts a heat exchanger that costs several hundred pounds to replace.

A boiler that keeps locking out is telling you something. Ignoring it usually means one of three outcomes: a component fails completely on the coldest week of the year, the fault damages a second, more expensive component, or a gas or flue issue that should have been found is left in place. Where a gas appliance is genuinely unsafe, it has to be turned off, and that decision is far more disruptive in January than it would have been in the autumn.

Then there is the money. Repeated call-outs from whoever is available, each replacing a plausible part, routinely add up to more than the correct repair or even a contribution towards a new boiler with a manufacturer warranty of 5, 7 or 10 years. Diagnosis first is the cheapest route, not the slowest one.

Common mistakes we are called out to

Repressurising the boiler again and again instead of finding the leak that is causing the drop.
Letting an unregistered handyman touch the gas side of a boiler, it is illegal and it invalidates warranties and insurance.
Skipping the annual service, which is the condition most manufacturer warranties depend on.
Fitting a brand-new boiler onto a system full of sludge, then wondering why it is noisy and inefficient within two winters.
Choosing a boiler by price alone rather than having the heat requirement and hot water demand of the house worked out.

Our Process

How the work runs, step by step

The same sequence every time, so you always know what happens next and what it costs before it happens.

1
Step 1: Inspection
We listen to what the system has actually been doing, then check the boiler, controls, pressure, gas supply, flue and radiators as one system rather than jumping straight to the fault code.
2
Step 2: Diagnosis
Readings, live gas and pressure checks and component testing identify the cause. You are told what has failed and why, in plain language, before anything is dismantled.
3
Step 3: Priced decision
The £80 + VAT call-out covers the first hour on site. If more time or parts are needed, you get the price and the options, repair, or a free written quote for replacement, and you choose.
4
Step 4: The work
Dust sheets down, parts fitted, pipework and controls corrected. Reviews from our customers repeatedly mention clean, careful work in occupied homes, including a Grade II listed property.
5
Step 5: Testing and verification
Gas rate and working pressure checked, combustion analysed where applicable, system rebalanced, controls proven, and hot water and heating run up in front of you.
6
Step 6: Completion and guarantee
Paperwork handed over, a 12-month workmanship guarantee on most work with terms explained for your specific job, and a direct number rather than a call centre if anything needs a second look.

The Benefits

What you actually get for the money

Speed when it is cold

Working from one base in Underwood, close to the M1, means short travel times and a genuine same or next-day response for most breakdowns within opening hours.

Safety proven, not assumed

Gas Safe registered No. 593241, ACS assessed and City & Guilds NVQ Level 3 qualified, with £2m public liability cover behind every visit.

Longevity built in

Sludge removed, systems balanced, correct inhibitor dosed and filters fitted where sensible, so the repair holds and the next boiler lasts.

Costs you can see coming

£80 + VAT diagnostics including the first hour, servicing from £75 + VAT, and fixed quotes on installations rather than estimates that creep.

One engineer, whole system

Boiler, gas, controls, radiators, pipework and unvented cylinders, G3 qualified and WaterSafe registered, so nothing gets passed to a second trade.

Peace of mind afterwards

A 12-month workmanship guarantee on most work, manufacturer warranties of 5, 7 or 10 years on new boilers, and customers who have stayed with us for 25 years.

In Detail

The heating work we cover, and how it is done

Heating engineering is a wide trade. Here is the detail behind the work we take on across Nottingham, Derby and the surrounding towns.

Boilers: combi, system and regular

Combi boilers heat water on demand and suit homes where one bathroom is in use at a time. System and regular boilers work with a stored cylinder and are usually the right answer for larger houses, two or more bathrooms, or where a shower needs strong simultaneous flow. Getting this choice right is a sizing exercise, not a preference, heat loss, hot water demand, gas supply and pipe sizes all decide it.

As a Baxi approved installer and Vaillant registered installer, those are our usual recommendations, and they carry manufacturer warranties of 5, 7 or 10 years depending on the model. If you have a brand preference we will work with it; if you would rather not choose, we will specify what suits the property.

Faults we diagnose most often

Ignition and flame-loss lockouts, faulty fans and pressure switches, blocked condensate pipes freezing in cold snaps, failed diverter valves that give heating but no hot water, seized three-port valves, dead pumps, faulty thermistors and PCBs, expansion vessels that have lost their charge causing pressure to swing, and slow leaks on valves, unions and towel rails.

Cold radiators are usually a system problem rather than a boiler problem: air at the top, sludge at the bottom, or a system that has never been balanced so the nearest radiators take all the flow.

Controls, cylinders and pipework

Modern controls do real work: correctly set thermostatic radiator valves, a well-sited room thermostat and a proper heating programme cut gas use without any loss of comfort. We fit and correct controls as part of repairs and installations rather than leaving a new boiler running on old, badly configured wiring.

Unvented hot water cylinders require a G3 qualification to work on legally. We hold it, and we are WaterSafe registered, so cylinder servicing, expansion vessel checks and safety valve work are covered in house.

Domestic only, and why that helps you

We do not take on commercial premises. Domestic-only means the parts van, the training and the diary are all aimed at houses, flats and rented properties, which is the difference between an engineer promising to come after a factory job finishes and one who can realistically reach you today or tomorrow.

Landlord work sits naturally inside this: CP12 gas safety certificates from £85 + VAT alongside a service, with any remedial work estimated in writing before it goes ahead.

Questions

Heating Engineer, your questions answered

Anything not covered here, call 07792 651029 and ask Chris directly.

How much does a heating engineer cost in Nottingham?

Our diagnostic call-out is £80 + VAT and includes the first hour on site. If the job needs longer or needs parts, we price it and get your agreement before continuing. Annual boiler servicing starts at £75 + VAT, landlord gas safety certificates from £85 + VAT with a service, and quotes for new boilers and heating installations are free.

How quickly can you get to a breakdown?

Same or next-day wherever possible during our opening hours: Monday to Friday 8:00am–6:30pm and Saturday 8:30am–12:00pm. Being based in Underwood, close to the M1, keeps travel times across Nottinghamshire and Derbyshire short.

Are you Gas Safe registered?

Yes, CSGHP Ltd is on the Gas Safe Register under number 593241, and you are welcome to check it before we arrive. We are also ACS assessed, City & Guilds NVQ Level 3 qualified, G3 qualified for unvented cylinders, BPEC certificated, an APHC licensed member and WaterSafe registered.

What guarantee do I get on the work?

A 12-month workmanship guarantee applies to most work, with terms varying for certain repairs, we will spell out exactly what applies to your job. New boilers also carry a manufacturer warranty of 5, 7 or 10 years depending on the boiler chosen.

Should I repair or replace my boiler?

It depends on the fault, the age of the appliance and what parts cost. We diagnose first, tell you what the repair involves, and if replacement makes better financial sense we provide a free written quote so you can compare the two properly rather than guessing.

I think I can smell gas. What should I do?

Turn the gas off at the meter, open windows, avoid switches and naked flames, and call the National Gas Emergency Service on 0800 111 999 first. Once the escape has been made safe, call us and we will pick up the repair.

Do you work on commercial buildings?

No. We are domestic only: houses, flats, landlords and letting agents. It keeps our gas and heating work focused where our training and experience are strongest.

Which areas do you cover?

Nottingham, Derby, Mansfield, Hucknall, Ilkeston, Beeston, Long Eaton, Matlock and Chesterfield. If your town is not listed, call and we will tell you straight away whether we can help.

How are payments handled?

Boiler installations are paid on completion, with a deposit requested in some situations. Larger projects that run across several visits are set up as staged payments.
