Service Overview

What a boiler repair visit involves

A repair visit is a diagnosis followed by a decision. We check the appliance and the system it sits on, gas supply and working pressure, electrical supply and controls, system pressure and flow, flue and condensate, and the components the symptoms point at, and identify what has actually failed rather than replacing the most likely part and hoping.

The cost is fixed and known before we set off: £80 + VAT, which includes the first hour on site. A large share of faults are found and fixed inside that hour. Where more time or parts are needed, you are given the price and the options and you decide whether we carry on. There is no meter running quietly in the background.

That matters because boiler repair is where homeowners most often get stung. Vague hourly rates, parts fitted speculatively, and repeat visits for the same symptom are the norm in the trade. CSGHP Ltd is Chris Smith's business, 23 years in the trade since 2003, an apprenticeship at British Gas, then E.ON and Vaillant, and the training shows in how quickly a fault gets named.

We repair boilers for homeowners, landlords and letting agents across Nottinghamshire and Derbyshire, on domestic properties only, with a same or next-day response wherever possible during opening hours: Monday to Friday 8:00am–6:30pm and Saturday 8:30am–12:00pm.

Who this is for

No heating or no hot water

A boiler that will not fire, fires but does not heat, or gives heating and no hot water: a classic diverter valve symptom.

Boilers that keep locking out

If you are resetting the boiler every few days, something is failing intermittently and it will not fix itself.

Pressure that keeps dropping

Repeated repressurising means a leak or a failed expansion vessel, and every top-up brings fresh oxygen into the system.

Noises, leaks and error codes

Kettling, banging, water under the boiler or a code on the display, all of them have a specific, findable cause.

Leave It and It Gets Worse

Why a small boiler fault rarely stays small

Boilers protect themselves by shutting down, which is why a fault often looks intermittent for weeks before it becomes permanent. During that period the underlying cause carries on doing damage. A failing fan makes the burner cycle badly. A blocked condensate trap fills with acidic water. A leaking system drops pressure, gets topped up, and pulls oxygenated water into steel radiators, producing the sludge that later blocks heat exchangers and kills pumps.

The escalation is expensive in a predictable way: a cheap sensor becomes a mid-priced valve, then a heat exchanger, then a boiler that is not economic to repair at all. Meanwhile the household pays for repeat call-outs from whoever is available, each replacing a plausible component.

There is a safety dimension too. Faults involving combustion, flue integrity or gas soundness are not cosmetic. Where a gas appliance is genuinely unsafe it has to be shut off, and finding that out in a cold snap, when every engineer in the county is already booked, is the worst possible timing.

If you can ever smell gas, do not wait for a repair appointment: turn the gas off at the meter, open windows, avoid switches and 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.

Common mistakes we are called out to

Resetting the boiler repeatedly instead of having the intermittent fault diagnosed.
Topping up pressure weekly and never finding the leak that is causing it.
Letting someone without Gas Safe registration work on the gas side, illegal, and it voids warranties and insurance.
Buying parts online and asking an engineer to fit them, with no warranty on either the part or the diagnosis.
Paying for three speculative repairs when the money would have been better put towards a new boiler with a 10-year warranty.

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: Phone triage
We ask what the boiler is doing, what it shows on the display and what changed. That often narrows the fault and tells us which parts to bring.
2
Step 2: Inspection on site
Gas supply, working pressure, electrical supply, controls, system pressure, flue and condensate all checked as a whole rather than chasing a single fault code.
3
Step 3: Diagnosis
Component testing and live readings confirm the cause. You are told what has failed, why it failed, and whether anything else is likely to follow it.
4
Step 4: Priced decision
The £80 + VAT visit covers the first hour. If more time or parts are needed you get the price, plus a free written quote for replacement if that is the better option.
5
Step 5: Repair and testing
Parts fitted, gas rate and pressures reset, combustion checked where applicable, system rebalanced, and heating and hot water proven in front of you.
6
Step 6: Completion and guarantee
Paperwork handed over and a 12-month workmanship guarantee on most work, with terms varying for certain repairs, always explained for your specific job.

The Benefits

What you actually get for the money

A response you can plan around

Same or next-day wherever possible in opening hours, from a single base in Underwood close to the M1.

Safe hands on the gas side

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

Repairs that hold

The cause is corrected, not just the symptom: including the system conditions, like sludge or a failed expansion vessel, that caused the failure.

No bill surprises

£80 + VAT including the first hour, and any further work priced and agreed before it starts. No open-ended hourly billing.

An honest repair-or-replace answer

If a repair is not worth the money we say so and give you a free written quote for a new boiler, so you can compare the two properly.

Care in occupied homes

Dust sheets, tidy work and genuine patience with elderly and vulnerable customers: the thing our reviews mention most often.

In Detail

Common boiler faults and how they are put right

Most breakdowns fall into a handful of categories. Recognising the symptom helps you describe it accurately when you call.

Ignition, flame loss and lockouts

A boiler that tries to fire and then locks out is usually a gas supply issue, a failed ignition electrode, a dirty or failing flame sensor, a fan or air pressure switch fault, or a blocked condensate route. Each has a distinct signature in the readings, which is why diagnosis beats parts-swapping.

Condensate blockages spike in cold weather when an uninsulated external pipe freezes. That is a same-day fix, and we insulate or reroute the pipe so it does not repeat every winter.

Heating but no hot water, and the reverse

On a combi, heating without hot water almost always points at the diverter valve or its actuator; hot water without heating often points at controls, a pump or a system blockage. On a system or regular boiler the same symptoms usually implicate the motorised valve, cylinder thermostat or wiring centre.

Weak or fluctuating hot water flow on a combi is frequently scale on the plate heat exchanger, or a partially blocked inlet filter, rather than the boiler failing.

Pressure loss, leaks and expansion vessels

Pressure that drops steadily means water is leaving the system: a radiator valve, a towel rail, a compression joint, a pinhole under a floor, or the boiler's own internals. Pressure that swings wildly between hot and cold usually means the expansion vessel has lost its charge, which is a chargeable but straightforward fix.

We trace the loss rather than simply refilling. Every unnecessary top-up shortens the life of radiators and pumps by introducing fresh oxygen into the system water.

Noise, cold radiators and when it is not the boiler

Kettling, banging and rumbling are usually system contamination or scale, not a broken appliance. Radiators cold at the bottom mean sludge; cold at the top means air; a whole floor cold usually means a balancing or pump issue.

In those cases a repair alone is a temporary answer. Power flushing, correct inhibitor dosing, a magnetic filter and proper balancing are what stop the same call-out happening next winter, and they protect any new boiler you fit afterwards.

Questions

Boiler Repair, your questions answered

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

How much does boiler repair cost in Nottingham?

£80 + VAT for the diagnostic call-out, which includes the first hour on site. If more time or parts are needed we price it and get your agreement before continuing, there is no open-ended hourly billing.

How soon can you come out?

Same or next-day wherever possible during our opening hours: Monday to Friday 8:00am–6:30pm and Saturday 8:30am–12:00pm.

Do you carry out emergency call-outs?

Yes: boiler breakdowns and gas faults, with a same or next-day response wherever possible during our opening hours. If you can smell gas, call the National Gas Emergency Service on 0800 111 999 first.

Is the repair guaranteed?

A 12-month workmanship guarantee applies to most work, with terms varying for certain repairs. We will tell you exactly what applies to your job before you commit.

Do you carry parts with you?

We carry common parts and ask diagnostic questions on the phone so we arrive with what your symptoms suggest. Where a part has to be ordered we tell you the timescale and the cost before ordering it.

Should I repair or replace an old boiler?

We diagnose first, then give you the repair cost and, where relevant, a free written quote for replacement. New boilers carry manufacturer warranties of 5, 7 or 10 years, which sometimes makes replacement the better financial decision, but you get the numbers and you choose.

Why does my boiler keep losing pressure?

Either water is escaping, a valve, joint, radiator or hidden pipe, or the expansion vessel has lost its charge. Both are findable. Repeated topping up is not a fix and it accelerates corrosion inside the system.

Can you repair a boiler in a rented property?

Yes. We work with landlords and letting agents, and can issue a CP12 gas safety certificate from £85 + VAT with a service at the same time.

Which areas do you cover for repairs?

Nottingham, Derby, Mansfield, Hucknall, Ilkeston, Beeston, Long Eaton, Matlock and Chesterfield, on domestic properties only.
