Gas Safe Engineer Pricing Guide: What to Charge in 2026

Gas Safe registered engineers in the UK charge rates that reflect their qualifications, liability, and the safety-critical nature of the work. As of 2026, the following rates represent typical national benchmarks — London and South East prices sit at the upper end or above these ranges:

• Boiler service: £80–£150
• CP12 landlord gas safety record: £60–£120 (single appliance); £100–£180 (multiple appliances)
• Gas safety inspection only (homeowner): £70–£130
• Boiler fault diagnosis / repair call-out: £80–£130 call-out plus £50–£90/hour
• Gas leak investigation and repair: £100–£400 depending on location and complexity
• Like-for-like combi boiler replacement: £1,800–£3,000 installed (mid-range boiler)
• System boiler + unvented cylinder: £3,000–£5,500 installed
• New central heating installation: £4,000–£8,000
• Emergency call-out (out of hours): £80–£180 call-out fee plus hourly rate

These figures are not a ceiling — experienced engineers with strong reviews and established reputations routinely charge above these rates and win work because customers choose trust and track record over price.

Location is one of the biggest drivers of what a gas engineer can charge. Labour costs, living costs, and competition density vary significantly across the UK:

• London (inner): 30–50% above the national average. A boiler service commonly runs £130–£180; a combi installation £2,200–£3,500+
• London (outer) and South East: 15–30% above national average
• South West and East of England: Near national average
• Midlands and North West: At or slightly below national average
• Yorkshire, North East, Scotland, Wales: Typically 5–15% below national average

Don't simply benchmark against national figures — survey what local competitors charge, what engineers on Checkatrade and MyBuilder are pricing in your postcode area, and what your actual costs demand. Rural engineers often face additional travel costs that push prices up despite being in lower-wage areas.

For job types where you charge by time rather than a fixed price (fault finding, commercial maintenance, investigative work), setting the right hourly rate requires calculating your actual costs first.

Start with your annual costs:

• Gas Safe registration: ~£150–£200/year (ACS category-dependent)
• Public liability and employer's liability insurance: £400–£1,200/year
• Van costs (finance, insurance, maintenance, fuel): £5,000–£10,000/year
• Tools and equipment (annualised): £500–£2,000/year
• Phone, software, accounting: £500–£1,500/year
• Your target salary

Divide total annual costs (including salary) by billable days (typically 200–220 for a sole trader) to get your minimum day rate. Add a profit margin of 15–25% to allow for investment in the business. Most gas engineers arrive at an effective day rate of £200–£320 for domestic work and £250–£400+ for commercial.

Translating to an hourly rate: divide your day rate by the number of productive hours you typically bill per day (usually 6–7 after travel and admin). At £250/day and 6 billable hours, your effective rate is roughly £42/hour — align your quoted hourly rate accordingly.

Gas certificates and compliance checks are a recurring revenue stream that many engineers undervalue. A well-priced certificate portfolio can generate £1,500–£3,000/month in stable income that doesn't depend on large installations.

Key certificate pricing:

• CP12 (Landlord Gas Safety Record): £60–£120 for a single appliance property; add £15–£30 per additional appliance. Do not price below £60 — this is a legal document with liability attached
• Gas commissioning certificate (new installations): included in the installation price; if billed separately on behalf of another contractor, £40–£80
• Building regulations notification (Part J/L): admin cost; typically included in installation quote
• CORGI-style homeowner inspection report: £70–£130 for a property-wide gas appliance check

Bundle CP12s with annual services wherever you can. The combined visit is convenient for landlords and efficient for you — one trip for two billable items.

Many gas engineers are charging rates they set years ago and haven't reviewed since. With gas prices, van costs, and material prices all rising since 2022–2023, a pricing review is overdue for most businesses.

Raising prices without losing customers requires positioning the increase correctly:

• Give notice — inform existing service contract customers 60 days before a price increase takes effect. This shows respect and reduces the shock
• Justify the increase — briefly explain that operating costs have increased. Customers understand this; they don't need detail, just acknowledgement
• Raise by increments — a 5–8% increase per year is largely invisible; a 20% jump after years of no change causes pushback
• Raise on new customers first — new customers have no prior reference point, so starting your new rate with them is the lowest-friction place to begin

In practice, most engineers who raise prices lose very few customers. The customers you lose on price were typically the most difficult anyway. The customers who value reliability, safety, and your track record stay regardless of a modest increase.
