Find a combi boiler installer in Hayle
An old boiler that keeps breaking down is the usual reason people start comparing combis. Tell installers what is on the wall now and how many bathrooms the house has.
One short description of the problem in Hayle can reach up to four independent heating engineers, depending on who works in your postcode. The matching is free. You can turn down every quote.
What the engineer will check
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.
What you might be seeing
- Several call-outs for the same boiler fault
- An engineer saying parts are no longer made
- Hot water that takes a long time to come through
- Pressure that keeps falling
- Wanting the airing cupboard back for storage
What the engineer does
Ask each installer to survey before giving a final price. On the day, the work usually covers:
- Draining 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.
- Mounting the new combi, flue, magnetic filter and controls.
- Connecting the gas, water and condensate pipes, upgrading the gas pipe if it is too small.
- Commissioning 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.
What to agree before work starts
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.
Prices for combi boiler replacement in Hayle
Budget around £2,000–£4,000 as a starting point. Your quotes may land above or below it. 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.
A useful quote shows labour, parts and any call-out fee as separate lines, with VAT stated. Allow 1–2 days for the work itself; awkward access or waiting for a part can take longer.
Information that speeds up a quote
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.
Read each quote line by line. 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.
Safety and regulations
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.
Building control questions for this area can go to Cornwall Council. Listed buildings and some conservation areas may have extra rules for flues and external pipework.

The free enquiry form takes a couple of minutes. We ask engineers who join for their insurance details and references, but ask to see an in-date insurance certificate and, for gas work, the Gas Safe card. We pass on your enquiry. The business you choose gives the advice, sets the price and carries out the work.
If you smell gas, leave the property and call the National Gas Emergency Service on 0800 111 999 (Great Britain). This service does not arrange emergency call-outs. In Northern Ireland, the gas emergency number is 0800 002 001; for LPG, contact your supplier.
Questions about combi boiler replacement
How can I compare quotes for combi boiler replacement in Hayle?
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 Hayle. 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 Hayle?
We use £2,000–£4,000 as a UK guide. Engineers in Hayle 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.
