One enquiry can put you in touch with up to four heating firms. There may be fewer than four replies, or none, if suitable engineers are unavailable in Grantham. The enquiry is free and you can decline every quote.
Understanding the work
A system filter collects debris carried by the heating water before it passes back through the boiler. Magnetic designs catch iron-oxide particles, and some collect other dirt too. Fitting one means checking the return-pipe layout, the product instructions and the space needed to isolate and service it later.
Why households request this work
Explain what has changed and what you would like the work to achieve.
- A replacement boiler needs a filter and water treatment to match its installation instructions.
- The system is being cleaned and you want to capture debris that continues to circulate.
- An engineer has identified magnetite contamination in the heating water.
- The existing filter leaks, is difficult to service or is unsuitable for the pipe arrangement.
- You want filter maintenance included in the heating service plan.
The work an engineer may include
The exact sequence depends on the existing system and the agreed scope.
- Inspect pipe sizes, the boiler return route and space for the filter body, valves and future servicing.
- Select a filter that fits the pipe arrangement and install it in an orientation permitted by its instructions.
- Agree whether system cleaning is needed separately and whether the filter is included in an existing boiler package.
- Protect the floor, isolate the relevant pipework and drain only as much of the circuit as the work requires.
- Cut and alter the heating return pipe, fit suitable joints and isolation valves, and mount the filter securely.
- Refill, vent and test for leaks; check water treatment and add the appropriate inhibitor where agreed.
- Show where the filter is and explain the cleaning interval, then remove offcuts and leave the pipework accessible.
Points to discuss at the visit
A magnetic filter only catches particles that pass through it. It does not remove sludge already settled in a radiator or repair a damaged pump. Cold radiators need diagnosis before deciding whether cleaning, balancing or another repair is required. A filter that cannot be opened because it is squeezed against a cupboard panel will be awkward to maintain, so service clearance matters as much as fitting space.
Guide prices for homes in Grantham
For initial budgeting, the site guide is £120–£300. Your property can fall outside that guide, so obtain a written price.
Installation cost depends on the chosen filter, pipe size and how easily the return can be altered. Cupboard restrictions and inaccessible drain points add work. A clean is an additional service if needed, so check whether the price is filter fitting alone or a larger cleaning package.
Ask for the total payable, including any applicable VAT. The site allows 1–2 hours as a guide; access and parts can extend this.
Useful details for your enquiry
Take a photograph of the visible pipework below or beside the boiler, without removing any covers. Give the boiler model, approximate radiator count and whether a filter or clean is already included in another quote. Mention restricted cupboard access or a history of leaks.
Safety and local property questions
Standalone water-side filter fitting does not automatically require Gas Safe registration. If access or associated work involves gas components or the boiler's combustion safety, the correct gas competence is required. Follow the boiler and filter manufacturers' installation and servicing instructions; fitting a filter does not guarantee a warranty or remove the need for maintenance.
Ask whether the price includes the filter, both isolation valves, inhibitor, leak testing and a demonstration. Do not pay twice if the same filter is already listed in your boiler replacement package.
For property-specific permissions or building control advice, contact Lincolnshire County Council. Explain the proposed work rather than assuming every heating job needs permission.

Useful answers before you choose
These answers cover common points raised before a heating visit.
How much does magnetic filter installation cost in Grantham?
The indicative site guide is £120–£300. Your quote depends on the equipment, system condition, access and agreed scope. Confirm the total payable and any exclusions with the engineer before booking.
Will a magnetic filter fix a cold radiator?
Not on its own if the fault is settled sludge, trapped air, a valve or poor balancing. A filter catches circulating debris; the engineer should diagnose the radiator problem and quote for any separate cleaning or repair.
Where should the filter go?
It is commonly fitted on the heating return before the boiler, subject to the manufacturer's instructions. The installer needs enough space for isolation valves and future cleaning.
How long does fitting a filter take?
The site guide is 1–2 hours for a straightforward installation. Restricted space, pipe alterations or additional cleaning can require more time.
Will I receive four quotes in Grantham?
Four quotes are not guaranteed. We can seek matches with up to four businesses, but responses depend on availability and the work required in Grantham. You may receive fewer replies or none, and you do not have to accept a quote.
