New Boiler Cost in Nottinghamshire 2026: What Installers Really Charge
What a new boiler actually costs in Nottinghamshire in 2026 — combi, system and regular, plus the extras that inflate quotes and how to spot them.
Ask three installers what a new boiler costs and you will get three answers, all of them vague. Here is what the work actually costs, itemised, based on the jobs we quote every week across Nottinghamshire.
The short version
| Job | Typical fitted price in Nottinghamshire | Time on site |
|---|---|---|
| Like-for-like combi swap | £1,800 – £2,500 | 4–6 hours |
| Back boiler removal to combi | £2,500 – £3,500 | 1–2 days |
| Open-vented to sealed combi conversion | £2,500 – £3,500 | 1–2 days |
| System boiler with unvented cylinder | £3,000 – £4,500 | 2 days |
Those are the ranges local independent installers typically charge, including the boiler. National installers and the energy companies generally sit above them for the same job, because you are paying for the call centre and the subcontractor margin. Our own quotes are given after a free survey rather than from a table — the reasons are below.
What changes the price
Boiler output and brand. A 24kW combi for a two-bedroom flat costs meaningfully less than a 35kW unit for a four-bedroom house with two bathrooms. Within the same output, a Worcester Bosch or Vaillant sits above an Ideal or Glow-worm — you are paying for build quality and warranty length.
Whether the system type changes. A straight swap — old combi off the wall, new combi on — is the cheapest job there is. The moment a cylinder and loft tanks come out, or the boiler moves to a different room, you are adding pipework, making good, and often a day of labour.
Where the boiler goes. Relocating from a bedroom cupboard to the kitchen means a new gas run, a new flue, and new heating and hot-water pipework. It is often the right call for the long term, but it is not a small addition.
The condition of the existing system. If the radiators are full of magnetite sludge, a new boiler fitted onto it will block its heat exchanger within a couple of years. A chemical flush might add £150; a full Magnacleanse power flush more. Skipping it is a false economy and most manufacturer warranties require it.
The extras that should already be included
This is where quotes diverge most, and where you should push back. A properly specified quote includes:
- Removal and disposal of the old boiler — and the cylinder and tanks on a conversion
- A magnetic system filter (Adey, Fernox or similar)
- A system flush appropriate to the condition of the pipework
- A room thermostat — Boiler Plus regulations require a control upgrade on every installation anyway
- Flue, condensate routing and any gas pipe upgrade needed to meet the boiler’s gas rate
- Commissioning, the Gas Safe certificate and the Benchmark logbook
- Building Regulations notification to your local authority
- Warranty registration with the manufacturer
If a quote is £300 cheaper and quietly excludes four of those, it is not cheaper.
Boiler Plus — the bit installers skip explaining
Since 2018, every gas boiler installation in England has had to meet the Boiler Plus standard. In practice that means the boiler must be at least 92% efficient and the installation must include time and temperature controls, plus one of: weather compensation, load compensation, flue gas heat recovery, or smart controls with automation and optimisation.
The practical upshot is that a “boiler only, no controls” quote is not a compliant installation. If someone offers you one, they are either not notifying the work or they are cutting a corner you will inherit.
What a new boiler costs town by town
The bands above hold across the county, but the housing in each town pushes most jobs towards one row of the table or another. This is which job you are most likely to be quoting for.
Worksop. Gateford and the newer estates are like-for-like combi swaps — the top row. Manton’s colliery housing still has back boilers, so a removal to a kitchen combi is the common job. The Victorian property near the Priory often needs a relocation to get a workable flue, which is the most involved of the three. Detail on the Worksop boiler installation page.
Retford. The town centre’s conservation area and solid walls push even a straightforward job up the table, because the flue and condensate have to be designed rather than assumed. Ordsall’s inter-war semis are open-vented conversions; the larger Hallcroft and Grove Street houses often want a system boiler and cylinder. See boiler installation in Retford.
Mansfield. Our home town, so no travel is priced in. Berry Hill and Forest Town are mostly straight swaps; the post-war estates at Ladybrook, Bull Farm and Ravensdale are open-vented conversions; the terraces off Chesterfield Road South and Bath Lane are back boiler removals. See boiler installation in Mansfield.
Everywhere else we cover — Sutton-in-Ashfield, Kirkby, Hucknall, Beeston, Clifton, Carlton, Tuxford and the villages — falls inside the same bands, and there is no travel charge on any of it. The boiler installations page lists every town.
What a quote from us includes
Every RPH quote is a complete fitted price, and it includes the boiler, the fitting, removal of the old unit, the magnetic filter, the flush, a free Hive smart thermostat, the Gas Safe certificate, Building Regulations notification, warranty registration and a free service at 12 months. It is a fixed written price after a free survey — what we quote is what you pay, and nothing is added on the day.
If you want a genuine number for your house rather than a range from an article, request a free survey or call us. We will tell you honestly if your existing boiler has years left in it, too.
Paying for it
Most people replacing a boiler are doing it because the old one failed, which is rarely a convenient moment financially. We accept bank transfer, credit card and cheque, and the price is fixed in writing before the job starts, so there is nothing to find on the day. If the budget is tight, say so at the survey — it sometimes changes which boiler makes sense, and a mid-range Baxi with a 10-year warranty is a better buy than stretching for a premium unit.
