An oil installation in Lincolnshire
More room inside
Ashby de la Launde Village Hall.
The hall was planning a new kitchen and had an old heating arrangement with tanks and a hot-water cylinder. After it won a boiler through a Worcester Bosch competition, our team installed an external Worcester Bosch oil combi.
We removed the outdated tanks and cylinder equipment and fitted the boiler outside. It was a practical way to free up indoor space for this building, with the hot-water arrangement chosen for the hall’s needs.
For your home, the same questions matter: where the boiler should go, how much hot water you use, and whether keeping a cylinder is the better choice.

What your oil boiler replacement includes
A survey before the fixed quote
We check the boiler, heating and hot-water demand, cylinder, controls, flue and condensate route. Tank condition, position, base and the oil supply are part of that assessment.
Safe access and careful removal
We agree how to get the old boiler out and the new one into position. We protect the work area, remove the old appliance and clean up afterwards. Oil boilers are heavy; we normally use two engineers for the handling.
The cleaning your system needs
We assess the water and circulation, fit a magnetic filter and specify suitable cleaning. A full powerflush is quoted where needed, not automatically added to every replacement.
Commissioning, paperwork and handover
We test and commission the installation, register the manufacturer guarantee and explain the controls and servicing requirements. Your quote sets out any separate tank, cylinder or supply work.
Tank requirements depend on the site and its surroundings. OFTEC’s oil-tank guidance explains why the position, base and environmental conditions need checking.
Choose around your home
Inside, outside,
with or without a cylinder.
The right oil boiler depends on the heat your home needs, how you use hot water and the space available. A bigger model or a combi conversion is not automatically an improvement.
Indoor oil boiler
A like-for-like indoor replacement may keep the work straightforward. We check clearances, the flue, oil supply, condensate and access for servicing. The boiler must suit its intended position.
External oil boiler
An outdoor model can release indoor space. Moving outside requires a suitable base, flue position, pipework, oil supply and condensate arrangement, all included in the survey and quote.
Regular or oil combi?
Keeping a sound cylinder can suit higher simultaneous hot-water demand. An oil combi can remove the need for a separate cylinder when mains flow and usage suit it. We check before recommending either.
Keep a sound tank when it makes sense
A new boiler does not automatically need a new tank. We assess what can safely stay and what needs work. If tank or oil-line changes are required, you see the scope and price before agreeing.
Considering a different heating system altogether? We can help you compare boiler and heat-pump options before committing to another oil boiler.
Clear cover and aftercare
The oil-boiler guarantee
belongs in your quote.
Manufacturer cover depends on the oil boiler, model and installation package. We confirm the exact term and conditions in writing, register the boiler after installation and explain the servicing needed to keep the cover valid.
A boiler guarantee does not automatically cover the oil tank, every control or all the older pipework in your home. We explain what is included and flag separate work.
Keeping your existing boiler for now? Our oil boiler servicing page explains the service and booking route. Confirm coverage for your postcode when arranging ongoing care.
From enquiry to handover
Three steps to a new oil boiler
Tell us about the existing setup
Let us know the postcode, whether the boiler is inside or outside, and whether you have a cylinder. Photos of the boiler, tank and access route can help when we follow up.
Survey and fixed quotation
We assess the system, check the tank and supply, and explain suitable options. You receive the agreed scope, manufacturer cover and fixed written price.
Installation and commissioning
A straightforward replacement normally takes one full working day. We agree the programme, protect the work area, test the system and show you how to use the controls.
Moving the boiler, converting from a cylinder or working on the tank and supply can take longer. We explain the expected heating and hot-water interruptions before work starts.

Practical advice for
off-gas homes.
Our team works from Unit 16, Witham Point, Wavell Drive, Lincoln, LN3 4PL. Liam has 23 years’ plumbing and heating experience and has surveyed more than 5,000 properties for boiler and heat-pump work.
An old oil boiler is not automatically finished. We consider its condition, repair history, parts availability and the cost of the present fault. If a sensible repair is the better option, we will say so.
If your property uses mains gas or LPG instead, our boiler installation team can help with those options too.

Before you decide
Your oil boiler replacement questions
How much does oil boiler replacement cost in Lincolnshire?
Our small-home guide examples are £3,913 for an internal regular boiler, £4,345 for an external regular boiler and £5,201 for an external combi, including VAT. These are straightforward like-for-like replacements with a standard flue arrangement and no additional powerflush, tank replacement or cylinder conversion. Boiler size, access, supply and extra work affect the final price, which we confirm after a survey.
Does replacing my oil boiler mean replacing the tank?
Not automatically. We assess the tank’s condition, base, position and oil supply. A sound, suitable tank may be retained. If tank or supply work is needed, we explain it and include the cost in the quotation before you decide.
Can you move an indoor oil boiler outside?
Often, but it needs a suitable external boiler and an assessment of the base, flue, oil supply, condensate route, pipework and access. An existing internal appliance cannot simply be put outside. Moving it is a different scope from the like-for-like external price examples.
Can I swap a regular oil boiler for an oil combi?
Sometimes. We first check mains flow, simultaneous hot-water use, boiler position and the work needed to remove the cylinder and tanks. For a household using several hot-water outlets together, keeping stored hot water may make more sense.
How long does it take to replace an oil boiler?
A straightforward oil boiler replacement normally takes one full working day. We normally use two engineers for the heavy appliance handling. Tank work, moving the boiler, cylinder conversion or extra pipework can extend the job, so we confirm the programme and expected interruptions beforehand.
Should I repair an old oil boiler instead?
Age alone is not a reason to replace it. We consider overall condition, repair history, parts availability, the current repair cost and the heating system around it. If a sensible repair is the better option, we will say so.
What guarantee comes with a new oil boiler?
The guarantee depends on the manufacturer, model and installation package. Your written quote states the exact term and servicing conditions. We register the boiler after installation and explain the cover. Do not assume a guarantee advertised for a gas boiler also applies to oil.
Will a new oil boiler definitely cut my bills?
No fixed saving is guaranteed. The change depends on the old boiler’s condition, the heating system, controls, how you heat the property and oil prices. We focus on a suitable appliance and proper commissioning rather than promising a percentage saving.
