Request free boiler and heating quotations
Use the form to explain what has gone wrong or what you want changed. Include your postcode and the equipment you have, even if you are unsure which component is faulty. Boiler Quotes can seek matches with up to four independent heating businesses; they assess and quote directly, and responses depend on local availability and the service required.
Submitting the enquiry costs nothing and does not commit you to a contractor. Fault-finding, leak investigations and some surveys may carry a charge from the engineer. Ask what the visit will cost, whether it is deducted from later work and what happens if no repair is possible.
Describe the job, then compare the scope
- Choose the relevant service and give your postcode, contact details and property information.
- Describe the symptoms, timing and any planned changes, including the current boiler or cylinder.
- Responding businesses can ask questions or arrange an assessment before pricing.
- Check the itemised quotations and appoint a business only when you understand the work and terms.
Work covered by the service
- Gas Boiler Replacement — Taking out a worn, uneconomical or condemned gas boiler and fitting a new condensing model, sized to the home's heat loss and hot water demand, with a new flue, condensate route, filter and commissioning paperwork.
- Hot Water Cylinder Replacement — Replacing a leaking, scaled-up or slow-to-heat hot water cylinder with a new vented or unvented (mains pressure) cylinder, including immersion heaters, valves, discharge pipework and the cylinder thermostat.
- Heating Controls Upgrade — Bringing old timers, dial thermostats and faulty zone valves up to date — programmable or smart room thermostats, a new programmer, thermostatic radiator valves, a cylinder stat and separate heating zones where the pipework allows.
- Magnetic Filter Installation — Fitting an inline magnetic system filter on the return pipe to the boiler so circulating iron oxide (magnetite) is caught before it reaches the heat exchanger and pump, with inhibitor topped up and the filter shown to the homeowner.
- Boiler Breakdown Diagnosis — A call-out to find out why a boiler has stopped — reading fault codes, testing ignition, fans, sensors, pressure and controls — so you know whether it is a quick fix, a part to order or a boiler not worth repairing.
- Central Heating Leak Detection — Tracing a hidden leak that keeps dropping boiler pressure or staining ceilings — pressure-drop tests, thermal imaging, acoustic listening and tracer gas — then opening up only the section of floor or wall needed to repair it.
Related work may include immersion heaters, motorised zone valves, radiator valves, balancing, inhibitor treatment, chemical cleaning, power flushing, condensate alterations and targeted pipe repair. Mention these when relevant, but let the engineer establish what is needed rather than ordering parts from a fault code alone.
Indicative UK costs
These are broad budgeting ranges, not offers or guaranteed prices. The first six rows use this site's service guide figures. The scope column explains why a diagnosis-only visit and an installation package should not be compared as the same job. Ask for a final total including any applicable VAT.
| Service or related task | Guide range | What to check |
|---|---|---|
| Gas Boiler Replacement | £2,000–£4,500 | Installed replacement; major relocation or conversion can exceed this range. |
| Hot Water Cylinder Replacement | £800–£3,000 | Vented or unvented replacement; supply and discharge alterations affect the total. |
| Heating Controls Upgrade | £150–£1,200 | Single-device work through to broader valve, wiring or zone upgrades. |
| Magnetic Filter Installation | £120–£300 | Filter fitting; substantial system cleaning is a separate scope. |
| Boiler Breakdown Diagnosis | £80–£450 | Broad allowance spanning diagnosis and some simple repairs; major parts can be extra. |
| Central Heating Leak Detection | £150–£750 | Investigation scope varies; opening finishes, repair and reinstatement must be specified. |
| Smart room thermostat, supplied and fitted | £200–£450 | Single compatible thermostat package; extra zones and subscriptions excluded. |
| Standard thermostatic radiator valve replacement | £40–£100 per valve | Quantity and any separate drain-down or visit charge affect the unit price. |
| Power flush for a typical domestic radiator system | £350–£800 | Radiator count, condition and access matter; this is not required for every job. |
Property size and hot water use shape the equipment choice. Boiler brand, cylinder size, flue length, gas pipe capacity, control compatibility, system condition and the quantity of radiator valves change the specification. Loft access, solid floors, parking, location and out-of-hours attendance can add cost. Confirm removal, clean-up and making good, and agree how unexpected work will be priced.
Published boiler installation examples from Worcester Bosch and British Gas repair packages provide context, but cover their own specified packages and exclusions. They are not quotations from this network. Specialist tracing, major repairs and complex conversions can exceed the guide figures.
Details that make the first conversation useful
- Boiler make, model, fuel and approximate age, plus the exact displayed fault code.
- Whether you have a cylinder, loft tanks or a combi, and how many bathrooms are used at once.
- Cold pressure readings and how quickly pressure falls; any visible drips or stains.
- Existing controls, the number of zones and the devices you want replaced.
- Cupboard or loft access, floor construction and parking restrictions.
- Any service cover, manufacturer warranty, insurer involvement or earlier diagnosis.
- Whether you own, rent or manage the property, and who can approve the work.
Check the person and the paperwork
Companies joining are asked for insurance details and references. Before appointing anyone, verify credentials for the actual work: HSE guidance on checking a Gas Safe engineer covers gas registration checks. Unvented cylinder work needs appropriate competence, and electrical controls need competent wiring work. Ask which notification and commissioning records apply in your UK nation and who will arrange them.
A boiler quotation should name the model, controls, filter, cleaning method and warranty conditions. A cylinder quotation should identify capacity, valves, immersion work and discharge arrangements. A diagnostic or leak quote should state included time, parts, return attendance, access and the limits of any making good. Confirm payment stages and the total payable in writing.
Urgent safety concerns
If you smell gas, suspect carbon monoxide or an alarm sounds, get to a safe place and follow HSE gas and carbon monoxide advice. Contact the appropriate emergency service for your location and fuel supply before requesting repair quotations. This form cannot arrange emergency response.
Frequently asked questions
Will I definitely get four quotations?
No. We can seek matches with up to four independent businesses, but the number of responses depends on availability, postcode and the work required. You may receive fewer or no replies.
Can I enquire without knowing what has failed?
Yes. Describe the symptoms and current equipment. A responding engineer can explain whether an assessment is needed and what that visit would cost.
Do I have to accept a quotation?
No. You can ask for clarification, compare the details or decline every quotation. Any agreement for work is made directly with the business you choose.
Is a breakdown visit free?
The quotation enquiry is free, but fault-finding attendance may be chargeable. Confirm the visit fee, included time, parts and return attendance charges before booking.
