How much does a new oil boiler cost to install in Hinckley, Nuneaton & Warwickshire?
If you’re off the gas grid, oil boilers are your main option. A new oil boiler costs £3,300 – £5,500 total (supply and installation), averaging £4,700 across the UK.
Oil boiler costs by type
| Boiler Type | Unit Cost Only | Total Installed |
| Oil Combi | £1,300 – £4,000 | £4,000 |
| Oil System | £1,800 – £3,000 | £3,500 |
| Oil Conventional | £1,000 – £3,500 | £3,300 |
| Heat Only | £1,700 – £4,500 | £3,300 |
Small properties (24–27kW): £1,700 – £5,500 total
Medium properties (28–34kW): £2,300 – £4,700 total
Large properties (35–42kW): £2,000 – £6,500 total
Oil boiler installation takes 1–3 days depending on complexity — longer than gas due to tank connections and OFTEC requirements.
Annual running costs for oil: around £1,883 (17,000 kWh typical). Heating oil currently costs £0.97 per litre, or 11.08p per kWh at 90% efficiency.
How much do commercial boilers cost to install in Coventry, Leicester & the West Midlands?
Commercial boilers are a different ballgame — size, output, and building use all shift the price.
| Commercial Boiler Type | Cost Range (installed) |
| Small commercial (up to 100kW) | £4,000 – £7,000 |
| Medium commercial (100–300kW) | £7,000 – £12,000 |
| Large commercial (300kW+) | £12,000 – £20,000+ |
Commercial installations cost more as they also require:
- Business-grade flue systems
- Enhanced water storage
- Compliance with tighter building regulations
- Often 2–5 days installation time
- Extra skills from engineers like us here at Hinckley Plumbing & Heating Services
We handle commercial boiler installation in Hinckley and across Leicestershire, Warwickshire, West Midlands, Staffordshire & Derbyshire.

Are there boiler installation grants available in Leicester and the Midlands?
Yes — but they’re specific.
Boiler Upgrade Scheme (England & Wales)
- £7,500 towards air source heat pump installation
- £7,500 towards ground source heat pump
- £5,000 towards biomass boiler
Eligibility:
- You own the property
- Replacing fossil fuel heating (gas, oil, electric)
- System capacity under 45 kWh
- Installing from 1 April 2022 onwards
Note: Hybrid systems (gas boiler + heat pump) don’t qualify.
There’s no general grant for standard gas/oil boiler replacements — those are privately funded.
Why Your Boiler Location Matters
This bit doesn’t need fact-checking — it’s just experience.
Boilers installed in awkward spots (loft, outbuilding, tight cupboard) cost more. Not because engineers are charging extra, but because:
- Flue routing gets longer
- Pipework needs more bends
- Access is slower
- Safety clearances matter
A boiler in an easy kitchen spot versus a loft with narrow stairs? That’s a £300–£800 difference sometimes. We’ll always tell you if moving it makes financial sense — often it doesn’t.
Frequently Asked Questions
How much is a new boiler in Leicester 2026?
A new gas combi boiler in Leicester costs £2,500 – £4,000 installed. Oil boilers are higher at £3,300 – £5,500. These are East Midlands averages, and Hinckley, Nuneaton, and Coventry fall in the same range.
Is it worth replacing a 10-year-old boiler in Hinckley?
If it’s working well and serviced annually, you might have 3–5 years left. Boilers last 10–15 years on average. But if you’re paying for repairs more than once a year or bills are climbing, replacement saves money long-term.
What’s the cheapest boiler type for Midlands homeowners?
Gas combi boilers are cheapest to install (£2,500–£3,500) and run (~£120/month). Electric boilers have lower installation but higher running costs (~£206/month) due to electricity prices.
Do I need a Gas Safe engineer for boiler installation in Leicestershire?
Yes. Gas boilers must be installed by a Gas Safe Registered engineer. Oil boilers require an OFTEC-registered technician. We’re both Gas Safe registered and APHC accredited — you can verify this before booking.
