What your installation includes
A proper check before the quote
We look at hot-water demand, water flow, the existing heating, flue, fuel supply and controls. You get suitable options and a written price for the agreed job.
Your home protected and the old boiler removed
We protect the work area, take the old boiler away and clean up afterwards. We’ll discuss access and any making-good work before we start.
System cleaning and a magnetic filter
We assess the cleaning your heating needs and fit a magnetic filter. A full powerflush is quoted where needed, not added to every installation.
Testing, registration and a useful handover
We commission the boiler, register its manufacturer guarantee and show you how to use the controls. We explain the paperwork and aftercare arrangements before we leave.
Our gas work is carried out by Gas Safe registered engineers. Check the Gas Safe Register.
Know what you’re buying
A clear guarantee.
A team you can call.
We offer boilers with 5, 7, 10 and 12-year manufacturer guarantees. Your written quote states the term for the model and package you choose, so there’s no guesswork.
We’ll register your boiler after installation and explain the servicing it needs. Tell us if you want ongoing servicing so we can confirm the available arrangements for your fuel and postcode.
The manufacturer guarantee covers the boiler under its terms. It is not unlimited cover for every part of your heating system.
From first call to warm home
Three straightforward steps
Tell us what you need
Call or send your details. Let us know if you’re without heating or hot water so we can check the earliest suitable appointment.
Survey, options and a fixed quote
We check the property, explain suitable boilers and confirm the work, guarantee and price before you decide.
Installation and handover
A straightforward replacement usually takes one full day. We agree the programme, test the installation and show you how everything works.
A cylinder-to-combi conversion normally needs around two days; a back-boiler conversion around three. Moving the boiler or finding extra system work can extend the job. We’ll explain likely heating and hot-water interruptions beforehand.
The right boiler for your home
Start with your hot water,
not a bigger boiler.
Two showers running together tell us more than the number on your old boiler. We check hot-water demand, incoming water flow and the heat your home actually needs before choosing a replacement.
Combi boiler replacement
Heating and hot water without a separate cylinder. Often a good fit where demand and mains flow suit it, but not automatically the answer for several bathrooms in use together.
System boiler replacement
A boiler serving a hot-water cylinder, with the pump and expansion vessel built in. We check both the heating and cylinder arrangement before recommending it.
Regular boiler replacement
Sometimes retaining a sound existing boiler-and-cylinder arrangement is the sensible choice. We won’t turn a straightforward replacement into a conversion you don’t need.
Oil or LPG instead of mains gas?
Not on mains gas? Our oil boiler replacement service covers indoor and external installations, including the tank and supply checks. For LPG, use this page’s form or price tool and tell us your fuel.

Local engineers based in Lincoln
Your Sleaford home.
Our Lincoln-based team.
We install boilers in Sleaford, Leasingham, Ruskington and Heckington. A straightforward combi swap and a house with a cylinder need different checks, so we start with your current heating, hot-water use and any changes you want to make.
Tell us about parking, side access or a boiler tucked into a tight cupboard when you enquire. We check how the old appliance will come out, where the new flue can run and whether the controls or pipework need changing. That detail belongs in the quote, before installation day.
You may know us as Central Plumbing & Heating. Our Lincoln boiler installation team now trades as Vector Heat, with the office at Unit 16, Witham Point, Wavell Drive, Lincoln, LN3 4PL.

Before you decide
Boiler installation in Sleaford: your questions
How much is a new boiler fitted in Sleaford?
Our small-home gas combi replacement guide options are £1,918, £2,201 and £2,528 including VAT. Those examples assume a straightforward combi swap with a wall flue and no additional powerflush. Your boiler size, flue, supply, controls and any conversion work can change the price. We survey before providing a fixed written quote.
Do you cover villages around Sleaford?
Yes. We take installation enquiries in Sleaford, Leasingham, Ruskington and Heckington from our Lincoln base. For another nearby village, give us the postcode so we can confirm the survey arrangements.
Do you have an office in Sleaford?
No. Vector Heat is based at Unit 16, Witham Point, Wavell Drive, Lincoln, LN3 4PL. Our team travels to Sleaford for boiler installations. You can reach our office on 01522 535335.
How long will the installation take?
A straightforward boiler replacement normally takes one full working day. A cylinder-to-combi conversion usually needs around two days. Moving the boiler, changing the flue route or undertaking extra system work can take longer. We explain the programme and expected interruptions before you agree.
Should I keep my hot-water cylinder?
That depends on mains flow, the cylinder’s condition and how your household uses hot water. Several bathrooms used together can favour stored hot water. We check the heating demand separately and explain whether retaining the cylinder or converting to a combi makes more sense.
Which boiler brands do you fit?
We can discuss Worcester Bosch, Vaillant, Ideal and Baxi gas boilers, depending on the job and the options available. The guide-price cards show Worcester Bosch examples, not the only boilers we can consider. The survey and your priorities decide the recommendation.
Is the 12-year guarantee included with every boiler?
No. Manufacturer terms vary by boiler and package. We offer 5, 7, 10 and 12-year options, with the precise term and servicing conditions confirmed in the written quote. We register the boiler after installation; wider heating-system faults are not automatically covered.
Can you replace an oil or LPG boiler near Sleaford?
Yes, we take oil and LPG installation enquiries as well as mains gas. Tell us the fuel, current boiler position and whether you have a cylinder. We check the relevant supply and installation requirements. Ask us to confirm ongoing servicing availability for your postcode separately.
