A boiler that locks out on a cold morning, radiators that stay lukewarm upstairs, or a landlord safety check that is due next week all create the same pressure. You need someone local, competent and properly certified, with a diagnosis and price you can feel confident about before work begins. Finding the best heating engineers in Cambridge takes more than a quick directory search, because boiler care, central heating design and plumbing faults often overlap in one visit.
Our top pick is Plumbox for all-round domestic boiler care and home heating upgrades in Cambridge, with services covering boiler servicing, repairs, installation, underfloor heating and general plumbing. That combination lets homeowners and landlords discuss routine boiler care and larger upgrade work with one local provider, rather than arranging separate enquiries for closely related jobs. KA Plumbing & Heating is another option for households seeking advertised 24-hour emergency cover. Cambridge Heating Solutions is worth considering for heating and plumbing work that also involves hot water storage systems.
What follows is a ranked shortlist of six firms to help you match your job to the right provider. Service breadth, gas competence, coverage around Cambridge and Cambridgeshire, availability for planned versus urgent work, and clear customer contact details all matter when making that choice. Use the comparison to narrow down firms whose services suit your property, then discuss the work and request a written quotation before committing to a booking.
Our selection criteria
The shortlist compares advertised boiler and heating services, fuel types, Cambridge-area coverage and emergency availability. The order reflects suitability for different jobs, rather than a promise about workmanship, customer reviews or response times. Each firm serves Cambridge or the surrounding county, but your address and the work required will determine whether it can take your booking.
For gas work, check the attending engineer’s current Gas Safe registration and the appliance categories they are qualified to work on. For larger replacements, national guidance on building work, replacements and repairs to your home explains when building regulations and competent person schemes apply. A clear service description helps narrow the field; an itemised quotation and the right credentials should settle your choice.

#1. Plumbox – Best for comprehensive domestic boiler care and heating upgrades
A local domestic heating and plumbing option focused on boiler servicing, repair, installation and underfloor heating alongside general plumbing.
Plumbox is an established local heating and plumbing company serving Cambridge and the surrounding areas, focused on domestic boiler care, installation and ongoing maintenance. That suits homeowners and landlords who want one point of contact throughout a boiler’s life, from annual servicing through to fault finding and eventual replacement, with related heating improvements handled in the same property.
For boiler care and home upgrades, its services cover boiler servicing in Cambridge, boiler repairs, new boiler installations and underfloor heating, with general plumbing work alongside heating. In practical terms, you can discuss a routine service visit or a repair that reveals wider system issues with the same firm you approach about replacing radiators in part of the house with underfloor heating. Landlords with several similar properties may find that continuity helpful for record keeping, while owner-occupiers planning phased improvements can arrange servicing and controls work around changes to heat emitters without briefing a new contractor each time.
The practical appeal is being able to discuss the boiler and the wider heating system together. If you are adding underfloor heating, ask how the design will account for room heat demand and floor construction, as well as how the controls will work with the existing radiators. These details determine whether the proposed changes suit your home. As with any gas work, confirm registration and the written scope before booking, and ask how servicing, repair findings and installation options will be documented for your records. For larger domestic upgrades, a clear written survey addressing heat loss and controls, together with aftercare arrangements, is more useful than a headline quotation alone.
Pros
- Domestic coverage across servicing, repairs and installations, plus underfloor heating
- Plumbing alongside heating, useful where leaks, valves or pipework affect boiler performance
- Cambridge and surrounding area focus, relevant to local housing types from terraces to new builds
- Suitable for consolidating routine maintenance and upgrade planning with one provider
Before booking
- For underfloor heating, request a survey covering floor construction, heating zones and integration with existing radiators
- For a boiler replacement, ask who handles commissioning, notification and warranty registration
Who it is best for: Cambridge homeowners and landlords who want one local specialist for boiler servicing, installation, repairs and underfloor heating.
#2. Cambridge Heating Solutions – Best for cost-conscious heating, plumbing and gas work
A Hardwick-based heating, plumbing and gas service that presents itself as a full-service local provider with an emphasis on cost-effective delivery.
For boiler care and home upgrades, this firm offers a complete heating, plumbing and gas service, covering central heating faults, boiler-related work and associated plumbing tasks that often accompany a heating job. The company says it has served the area for over 17 years and describes a large and established client base, giving customers some background on its local operating history. Its emphasis is on cost-effectiveness without compromising customer care, alongside peace of mind that work is carried out to the required standard.
That approach will appeal to homeowners planning routine domestic work, whether a boiler service, a repair or a like-for-like replacement where clear communication and careful pricing matter. A full-service scope can reduce handoffs when a boiler fault involves pumps, valves, controls or minor pipework changes. As with all firms in this guide, agree the exact scope in writing before the visit, including what a service covers, how faults are diagnosed and what documentation follows an installation.
The offer suits planned domestic heating and plumbing work where a single firm can assess the system as a whole. Households comparing options should ask about appointment arrangements and parts sourcing, along with the guarantees that apply to the proposed work, and should check gas credentials for any gas appliance work.
Pros
- Over 17 years serving the local area, giving context on its operating history
- Full heating, plumbing and gas scope in one firm, helpful for linked faults
- Explicit emphasis on cost-effective delivery alongside customer care
- Cambridgeshire base serving the wider Cambridge area
Before booking
- If your fault involves a hot water cylinder, provide its make and model as well as the boiler details
- Ask how the advertised 12-month parts and labour guarantee applies to your quotation
Who it is best for: Homeowners who want a full-service local firm for planned heating, plumbing and gas work with attention to cost control.
#3. Moore’s Plumbing & Heating – Best for boiler, heating and bathroom work for homes
A Cambridge-based plumbing and heating provider with Gas Safe registered engineers serving local homes.
For boiler care and home upgrades, the services include new boiler installation, urgent boiler repair, bathroom fitting and full heating system work. That breadth is practical because heating upgrades often touch bathrooms, cloakrooms or kitchen pipework, and a firm accustomed to both plumbing and heating can plan the order of work around those connections. The company covers Cambridge and the surrounding Cambridgeshire area, with phone and email enquiry routes for domestic customers. Gas Safe registration is an important credential for landlords who must demonstrate compliance and for homeowners arranging gas work, although the attending engineer’s qualifications still need to cover the particular appliance.
The service mix suits residential customers who need fault response plus the option to commission larger heating system changes with the same team. Enquirers should provide the boiler make and model and describe the fault symptoms, system type and property size, then ask whether the proposed visit is for diagnosis, repair or a quotation survey.
The appeal is a broad range of services at a domestic scale, supported by Gas Safe credentials. Those comparing providers should ask how the firm handles servicing reminders, repair warranties and installation aftercare, and should keep written records of completed work for landlord compliance.
Pros
- Gas Safe registered engineers, relevant for gas boiler work and landlord duties
- Serves homes across Cambridge and Cambridgeshire
- Covers boilers, full heating systems and bathrooms, useful for linked projects
- Cambridge base with Cambridgeshire coverage
Before booking
- Distinguish between a boiler service, a landlord gas safety check and a fault-finding visit when requesting a price
- Its service list includes LPG installations and air source heat pump servicing; describe the appliance and the exact work you need
Who it is best for: Homeowners seeking boiler, heating and bathroom work, with Gas Safe registered engineers for gas tasks.
#4. AM Heating Services Ltd – Best for boiler repair across gas, LPG and oil
A heating, plumbing and boiler repair specialist offering work across gas, LPG and oil systems.
For boiler care and home upgrades, multi-fuel coverage is the main reason to consider this firm. Its engineers repair or maintain gas, LPG and oil systems, which matters in parts of Cambridgeshire beyond the mains gas network where cottages, farmhouses and village properties may rely on oil or LPG. Based in Papworth Everard, the company advertises coverage across Cambridgeshire and its borders, including CB and PE postcode areas. The core offer centres on heating, plumbing and boiler repair, with fault diagnosis and system maintenance forming a central part of the service.
If your home uses oil or LPG rather than mains gas, start with firms that explicitly offer work on that fuel type. Starting with a provider that lists all three fuels helps avoid spending time on an enquiry to a firm whose services do not match your appliance or the work you need. Ask the engineer to explain the fault and available repair options, including expected parts costs, before deciding whether replacement is worth considering. Those on mains gas can still use the service for standard boiler servicing and repair, but its multi-fuel coverage is particularly relevant to mixed-fuel households and rural properties.
When enquiring, give the fuel type and boiler brand, along with its age and service history, and describe whether the issue is intermittent lockout, pressure loss, noise, poor heat distribution or hot water failure. Ask what is included in a maintenance visit and how parts availability differs by fuel type, so you understand what the initial appointment covers.
Pros
- Gas, LPG and oil repair and maintenance, valuable outside mains gas areas
- Boiler repair focus alongside general plumbing and heating
- Advertises Cambridgeshire and border-area coverage from its Papworth Everard base
- Useful for rural properties with mixed or older systems
Before booking
- Provide the fuel type and appliance model; qualifications must cover the work being requested
- The service list includes emergency breakdowns, so ask about attendance and any return visit when reporting an urgent fault
Who it is best for: Properties running on LPG or oil as well as gas, including rural Cambridgeshire homes needing engineers across fuel types.
#5. Entire Group Ltd – Best for combined domestic and commercial heating and plumbing projects
A Cambridgeshire-based provider of domestic and commercial plumbing and heating with a focus on projects and maintenance.
For boiler care and home upgrades, the firm offers domestic and commercial plumbing and heating across Cambridge, with Gas Safe engineers, central heating work, air source heat pumps and planned preventative maintenance. Founded in 2007 and based just outside Cambridge, its services extend beyond single boiler jobs. That makes it relevant where a landlord holds a mix of residential lets and small commercial units, or where a homeowner is considering a heat pump alongside or instead of a gas boiler.
The combination of central heating, heat pumps and planned maintenance gives homeowners more than one heating option to discuss. A property assessment comes first. Homeowners exploring underfloor heating in Cambridge as part of a low-temperature system, improved controls or fabric upgrades may find that project approach helpful, provided the survey addresses insulation and radiator sizing as well as hot water demand, rather than treating a heat pump as a like-for-like appliance replacement.
Enquirers should ask how the survey will be carried out and request the system design assumptions in writing, together with maintenance plan terms and handover documentation. For commercial elements, clarify compliance paperwork, access arrangements and responsibility for ongoing servicing before agreeing the work.
Pros
- Covers domestic and commercial plumbing and heating, useful for mixed portfolios
- Offers central heating, air source heat pumps and planned preventative maintenance
- Founded in 2007, with an established local operating history
- Cambridgeshire base serving Cambridge and the wider area
Before booking
- For a heat pump proposal, ask for room-by-room heat demand, radiator requirements and hot water provision
- For a maintenance agreement, compare included visits, exclusions and breakdown attendance terms
Who it is best for: Clients needing a firm that can handle both domestic and commercial plumbing and heating, including planned maintenance and heat pump considerations.
#6. KA Plumbing & Heating – Best for advertised 24-hour emergency plumbing and boiler response
A plumbing and boiler service that advertises round-the-clock emergency cover within a defined radius of Cambridge.
For boiler care and home upgrades, emergency availability is a main reason to consider this firm. It advertises a 24-hour emergency service for plumbing and boiler issues and defines coverage as within a 30-mile radius of Cambridge, with phone contact for urgent callouts. That clarity helps households and landlords decide in advance who to call for a major leak, loss of heating in winter or a boiler fault that cannot wait until morning. Its combined plumbing and boiler coverage means water and heating faults that interact, such as burst pipework affecting system pressure, can be discussed in the same call.
For emergency work, ask about triage and temporary making safe, as well as follow-up repair and charges for out-of-hours attendance. Callers should describe the severity and any isolation steps already taken, give boiler display codes and details of water damage, and ask what will happen on the first visit versus a return visit. For non-urgent goals such as boiler servicing or a full heating redesign, the same firm can still be contacted, but customers should compare the planned survey process and quotation with other providers offering the work they need.
The defined radius helps set expectations before an emergency arises. Households near the edge of the area should save contact details and ask about attendance terms in advance, rather than leaving that conversation until there is an urgent fault.
Pros
- Advertises 24-hour emergency plumbing and boiler service for urgent faults
- Clear 30-mile radius around Cambridge, easy to check eligibility
- Phone access suited to time-critical triage
- Combined plumbing and boiler cover for leaks that affect heating
Before booking
- Ask what the fixed job price includes, particularly diagnosis, parts and a possible follow-up visit
- For planned work, request a separate installation or servicing quotation rather than relying on emergency-callout terms
Who it is best for: Homeowners and landlords who want round-the-clock emergency plumbing and boiler cover within the Cambridge area.
Frequently asked questions
How much should I budget for boiler work?
Costs vary by job type, boiler model, parts and access, so a diagnostic visit, a like-for-like replacement and a system conversion are priced differently. Ask for an itemised written quotation that separates labour and parts from controls, flushing, certification and aftercare, so you can see what the total actually covers. Compare the scope, not just the total: one installer may include new controls or pipework that another has excluded. If your work is being arranged through a support scheme, its installation standards matter too. The 2026 Warm Home Discount provisions for boiler and central heating work set out TrustMark or equivalent quality-assurance conditions for covered installations, and TrustMark conditions for covered repairs. This is a scheme-specific framework, not a requirement that every privately funded boiler job uses TrustMark.
What is the difference between a plumber and a heating engineer?
A plumber typically handles water, pipework, bathrooms and general plumbing faults, while a heating engineer focuses on boilers, central heating, controls and system performance. Many local firms cover both, which helps when a heating fault involves valves, pumps or pipework and the cause needs to be traced across the system. For any gas boiler task, check that the individual attending is qualified for the gas work you are requesting.
Do engineers need to be Gas Safe registered for gas boiler work?
For professional gas boiler work, use a Gas Safe registered engineer qualified for the appliance and work involved. Ask to see their ID card and check the relevant categories on the back. Keep the service report and any applicable installation paperwork together so they are available when needed. Landlords should book the required gas safety check separately from, or explicitly alongside, boiler servicing: a service and a landlord gas safety record are not interchangeable.
How often should I have my boiler serviced?
Annual servicing is usual for domestic boilers, but follow your manufacturer’s instructions and warranty terms for your particular appliance. A landlord’s gas safety check is a separate obligation, even when arranged at the same visit. Annual servicing also creates a documented history that helps with fault diagnosis and resale. If the boiler is heavily used, ageing or showing intermittent faults, do not wait for the anniversary to seek advice.
Can underfloor heating work alongside existing radiators?
It can, but the design needs to account for the different heat outputs, water temperatures and controls each part of the system requires. Ask for an assessment of room heat demand, insulation and floor construction before choosing a system. For a retrofit, discuss changes to floor height and finishes as well as installation disruption. A quotation should explain how the underfloor heating will connect to the existing heat source, how the rooms will be controlled and what work is needed to the radiators or pipework.
What should I look for when choosing a heating engineer?
Look for clear Gas Safe credentials and a service scope that matches your job, backed by transparent written terms and coverage that includes your address. When comparing heating engineers in Cambridge, ask how they survey the property and what the quotation includes, then discuss guarantees and how aftercare is handled. Keep records of servicing, repairs and certificates in one place for future reference, whether you are maintaining your own home or managing a rental property.
