Compare quotes for combi boiler replacement in Marshfield
Parts for an older combi can become hard to find, and that often decides the question. Give the current boiler make and say whether there is a hot water cylinder.
One enquiry about the job in Marshfield can reach up to four independent heating engineers, depending on the job and which engineers are free. The matching is free. You can turn down every quote.
Work to include in your enquiry
A new combi heats the radiators and gives hot water on demand from the mains, so there is no cylinder to reheat. Most quotes are for a swap in the same position. Some include moving the boiler or converting a system with a cylinder, and those take longer and cost more.
Things to mention when you enquire
- Repeat breakdowns over the last two winters
- A model with discontinued spares
- Hot water that runs cold when a second tap opens
- A boiler that locks out with the same code
- A cylinder and loft tanks you would like gone
On the day
A proper survey should come before the final price. On the day, the work usually covers:
- Emptying the system and removing the old boiler, plus any cylinder or tanks no longer needed.
- Cleaning the pipework and radiators with a chemical or power flush.
- Fitting the new combi, flue, magnetic filter and controls.
- Making up the gas, water and condensate pipes, upgrading the gas pipe if it is too small.
- Testing the boiler, completing the Benchmark checklist and showing you the controls.
Sizing means checking heat loss and hot water demand
The installer should assess the home’s heat loss as well as its hot water demand. Mains flow and pressure limit what reaches the taps, so a higher hot water output alone will not solve a weak supply. Ask how the proposed boiler meets both needs.
Access and finishing up
Protect the route used to carry the old boiler out. Agree who patches redundant flue holes and cupboard openings, and check that the installer removes only tanks no longer needed by the property.
The cost of combi boiler replacement in Marshfield
Our indicative allowance is £2,000–£4,000. Engineers here price their own work. A basic swap in the same position can sit towards the lower end of the range, though many cost £2,500–£4,000. A new flue route, a larger gas pipe, smart controls or a full conversion from a cylinder system moves it towards the top, and premium boilers or long warranties can go beyond it.
Ask for the call-out fee, parts and labour to be shown separately, with VAT stated. Allow 1–2 days for the work itself; awkward access or waiting for a part can take longer.
Before you send the form
Read the make and model from the data badge, usually under a flap or on the side of the boiler. Say where the boiler is, how many radiators and bathrooms the house has, and whether there is a cylinder. A photo of the boiler and the pipes below it helps.
Then pin down what the price covers. Ask for the boiler model and output, the flush type, the filter, the controls, the flue and gas pipe work, disposal and the warranty length to be listed. Two prices for “a new combi” are only comparable when those lines match.
Rules that apply to the work
Only an engineer on the Gas Safe Register can fit a gas boiler legally. In England and Wales, a new gas boiler installation is notifiable and the installer normally arranges the Building Regulations compliance certificate. Ask which approval and completion documents apply in Scotland or Northern Ireland. In England, Approved Document L sets the controls and efficiency expected with a new boiler.
If you are not sure whether building control needs to know, ask Newport City Council. Listed buildings and some conservation areas may have extra rules for flues and external pipework.

Before booking this work
How can I compare quotes for combi boiler replacement in Marshfield?
Fill in one enquiry form with your postcode and details of the current boiler, flue route and any cylinder to remove. It can go to as many as four independent heating engineers who work in Marshfield. How many reply varies with the job and how busy engineers are, and booking any of them is up to you.
Roughly how much is combi boiler replacement in Marshfield?
We use £2,000–£4,000 as a UK guide. Engineers in Marshfield price their own work, and the system, access and parts affect the total. A written quote should list labour, parts, VAT and any call-out fee.
Will a new combi give enough hot water for two showers?
It depends on the boiler output, incoming mains supply and shower flow rates. Two showers share the available hot water. Ask the installer to assess simultaneous demand and compare a cylinder system if that would suit the household better.
Will the heating be off all day when the combi goes in?
A like-for-like swap normally takes one day, with heating and hot water off for most of it. A conversion from a cylinder system often takes two days. Ask the installer to confirm the plan before the date is booked.
Do I need a magnetic filter with a new combi?
Most manufacturers expect a filter and a clean system as part of the warranty terms. A filter catches sludge before it reaches the new heat exchanger. Check it is listed in the quote.
How long should I allow for combi boiler replacement?
Allow 1–2 days as a guide. Once the engineer has seen the system, they should tell you how long the heating or hot water will be off. Waiting for a part or awkward access can add time.
