Heating, ventilation, and air conditioning work is one of the most technically demanding — and most regulated — trades in the UK. Whether you are a Gas Safe registered heating engineer, an F-gas certified refrigeration technician, or a multi-skilled HVAC installer, getting your pricing right is essential. Charge too little and your qualifications and expertise are undervalued. Charge too much without justifying the cost, and customers go elsewhere.
This guide breaks down how to price every major type of HVAC work in the UK, from straightforward boiler swaps to complex heat pump installations and ongoing service contracts.
1. The True Cost of Running an HVAC Business
HVAC work carries higher overheads than many trades due to mandatory certifications, specialist equipment, and ongoing training requirements. Before setting your prices, account for all of these:
Certification and Compliance Costs
- Gas Safe registration: £350–£500 per year (depending on appliance categories)
- F-gas certification: £800–£1,500 for the initial course, plus £200–£400 for five-yearly renewal
- OFTEC registration (oil heating): £400–£600 per year
- MCS certification (for heat pump installations eligible for government grants): £1,500–£3,000 initial, plus annual fees
- Manufacturer training courses: £200–£800 per course (often required to offer manufacturer warranties)
Equipment and Tools
- Flue gas analyser (mandatory for gas work): £400–£1,200, plus annual calibration at £80–£150
- Refrigerant recovery equipment: £500–£1,500
- Vacuum pumps, manifold gauges, leak detectors: £300–£800
- Pipe bending, pressing, and soldering equipment: £200–£600
- Van stock — common parts, fittings, and consumables: £500–£2,000 maintained stock
Tip: Add up all your annual certification, insurance, and equipment costs. Divide by your billable days per year (typically 220–230 for HVAC engineers). This is your daily overhead — the amount you must earn before you make any profit.
2. Boiler Installation Pricing
Boiler replacements are the bread and butter of many heating businesses. Getting your pricing consistent and accurate here is critical, as this is one of the most price-compared services in the trade.
Typical Boiler Installation Prices (UK, 2026)
- Combi-to-combi swap (same location): £1,500–£2,200 including boiler
- Combi-to-combi with relocation: £2,000–£3,000
- System boiler with cylinder: £2,500–£3,500
- Back boiler removal and replacement: £2,500–£4,000 (significant additional work)
- Full system conversion (gravity to sealed, or conventional to combi): £3,000–£4,500
What to Include in Your Boiler Quote
- The boiler unit — specify make, model, and output. Use your trade account pricing and apply your markup (typically 15–25% on the boiler)
- Ancillary parts: Magnetic filter, system flush, new gas cock, flue kit, condensate pipe, TRVs, room thermostat or smart thermostat
- Labour: Typically 1–2 days for a straightforward swap. Allow extra time for system conversions or difficult access
- Gas Safe notification: Mandatory legal requirement — build the cost into your price
- Warranty registration: Most manufacturers require installer registration to activate extended warranties
- Waste removal: Old boiler, packaging, and any removed pipework
Using QuoteGuru's template system, you can save standard boiler installation packages as reusable templates. This means you can quote a boiler swap in under two minutes on site, adjusting only the specific details for each job.
3. Heat Pump Installation Pricing
The heat pump market is growing rapidly in the UK, driven by the Boiler Upgrade Scheme grants and the push towards net zero. If you are MCS-certified, this is a significant revenue opportunity.
Typical Heat Pump Prices (2026)
- Air source heat pump (ASHP): £8,000–£15,000 (before BUS grant of £7,500)
- Ground source heat pump (GSHP): £15,000–£35,000 (before BUS grant of £7,500)
- Hot water cylinder upgrade (often required): £800–£1,500 additional
- Radiator upgrades (larger rads for lower flow temps): £200–£400 per radiator
System Design Fees
Heat pump installations require detailed system design, including heat loss calculations, emitter sizing, and flow temperature planning. Many engineers charge a separate design fee:
- Basic heat loss survey and system design: £200–£500
- Full MCS-compliant design package: £400–£800
As with garden design in landscaping, offering to deduct the design fee from the installation cost if the customer proceeds is a strong incentive for conversion.
4. Air Conditioning Installation
The UK AC market has grown substantially as summers become warmer. If you hold an F-gas certification, this is profitable work with good margins.
Typical AC Installation Prices
- Single split unit (one room): £1,200–£2,500 installed
- Multi-split system (2–4 rooms): £3,000–£7,000 installed
- Commercial VRF/VRV system: £10,000–£30,000+ depending on building size
F-gas certification is a legal requirement for working with refrigerants. If you do not hold one, the course costs £800–£1,500 and opens up a highly profitable market segment. The certification is valid for five years. Working without it carries fines of up to £15,000 and potential prosecution.
5. Service Contracts and Maintenance Plans
Service contracts are the most reliable form of recurring revenue in the HVAC trade. They fill your diary during quieter periods, build customer loyalty, and generate a steady stream of referrals and upgrade opportunities.
Structuring Your Service Plans
- Basic annual service: £80–£120 per year. Covers an annual boiler service and safety check. No parts or repair cover
- Standard plan: £120–£200 per year. Annual service plus priority call-outs and a small parts allowance
- Premium plan: £200–£300 per year. Full cover including annual service, parts, labour for breakdowns, and 24-hour emergency response
For a business with 200 service plan customers at an average of £150 per year, that is £30,000 in guaranteed annual revenue before you have quoted a single installation job. This kind of financial stability is invaluable, especially during the quieter summer months when boiler installations slow down.

6. Emergency Heating Repairs
Emergency work is stressful but highly profitable if priced correctly. Customers expect to pay a premium for urgent service, and you should charge accordingly.
Emergency Pricing Structure
- Standard hours call-out fee (8am–6pm, Mon–Fri): £80–£150
- Evening and weekend call-out: £120–£200
- Bank holiday / out-of-hours: £150–£250
- Hourly rate on top: £60–£100 per hour (standard), £90–£150 per hour (out-of-hours)
- Parts: Charged at list price plus 20–30% markup, or from your van stock at a standard markup
Always communicate your emergency pricing clearly before attending. Send the customer a text or email confirming the call-out fee and hourly rate so there are no disputes when the bill arrives. Digital quoting tools make this quick and professional.
7. Gas Safe and Compliance: Pricing the Paperwork
HVAC engineers have more compliance obligations than most trades. This paperwork takes time, and your pricing should reflect it:
- Gas Safe notification (Building Regulations compliance): Takes 10–15 minutes per job. Build this into your installation price rather than listing it separately
- Landlord Gas Safety Certificates (CP12): £50–£90 per property for a standard gas safety check
- Benchmark commissioning checklist: Required by all boiler manufacturers for warranty validation. Factor in 15–20 minutes per installation
- MCS documentation (heat pumps): Substantial paperwork including EPC, heat loss calculations, system design, and commissioning certificates. Allow 2–4 hours of admin time per heat pump installation
8. Quoting Tips Specific to HVAC Work
- Always survey before quoting: A boiler in a loft space versus a kitchen takes very different amounts of time. Never quote blind from a phone call alone for installations
- Photograph everything: Take photos of existing pipework, flue routes, electrical supplies, and access points. These save you from surprises on installation day and serve as evidence if disputes arise
- Specify make and model: Customers compare quotes. If your quote says "new combi boiler" and your competitor specifies the exact model with a 10-year warranty, they look more professional. Use QuoteGuru's item library to store detailed product specifications
- Include exclusions: Clearly state what is not included — asbestos removal, electrical work by a Part P electrician, building control fees, or additional radiators
- Offer good-better-best options: Give the customer three tiers. For example: budget boiler with 5-year warranty, mid-range with 7-year warranty, and premium with 10-year warranty. Most customers choose the middle option, which should be your most profitable tier
9. Common HVAC Pricing Mistakes
- Not charging for surveys: A full heat pump survey can take 2–3 hours. If you do not charge and the customer goes elsewhere, you have lost half a day for nothing
- Absorbing compliance costs: Gas Safe notifications, Benchmark paperwork, and MCS admin are real costs. Build them in
- Ignoring seasonal patterns: Boiler work peaks October–February. AC peaks June–August. Price accordingly and push service work during off-peak months
- Undervaluing your certifications: Gas Safe, F-gas, OFTEC, and MCS certifications cost thousands to obtain and maintain. Your pricing must reflect this investment
- Not collecting deposits: Always take a deposit before ordering a boiler or heat pump. A 30–50% deposit is standard practice and protects your cash flow
