The cost varies considerably depending on style, size, roofing specification and the complexity of your plot and groundwork.

A lean-to or Edwardian conservatory in uPVC starts from several thousand pounds, while a larger Victorian, gable-end or orangery with a warm roof will be significantly more.

The most accurate way to get a price is to book a free design visit; we’ll come out, measure your space, discuss what you’re looking for, and provide a clear written quote with no obligation. 0% finance is available to spread the cost.

A straightforward lean-to or Edwardian conservatory typically takes 3–5 days to install once the base has been prepared.

Larger or more complex designs may take up to 5–10 days.

Warm roof conversions on existing conservatories are usually completed in a day or two.

Lead time from order to installation is typically 4–8 weeks depending on specification; we’ll confirm an accurate timeline when you place your order.

For year-round usability, we’d recommend a warm tiled roof for most homeowners.

Lincolnshire’s climate, with cold winters and exposure to coastal winds, makes a poorly insulated conservatory uncomfortable for a large portion of the year.

A warm roof delivers a fully insulated ceiling that makes the room genuinely comfortable in January as well as July.

If maximum natural light is the priority, a solar-control glass roof is an excellent option. Polycarbonate is the most affordable route but the least thermally efficient.

Yes.

It’s one of the most popular services we offer.

If your existing conservatory frame is structurally sound, we can replace the polycarbonate or old glass roof panels with a fully insulated warm roof system, usually within a single day.

The transformation is dramatic.

In most cases, no planning permission is required as you’re replacing like-for-like on an existing permitted development structure.

We’ll confirm this for your property during a free assessment visit.

Yes.
All our conservatory installations are guaranteed on both materials and workmanship.

Specific terms are confirmed with your written quote.

We’re a local independent business and our reputation depends entirely on the quality of what we install.

If anything isn’t right after completion, we’ll come back and put it right.

In most cases, no.

The majority of conservatory installations in England fall under permitted development rights, meaning no planning permission is required.

Key conditions include: the conservatory must not exceed 50% of the original garden area, must not be taller than the existing roofline, and must not extend beyond the rear wall by more than 4 metres for a detached property or 3 metres for a semi-detached or terraced house.

Exceptions apply to listed buildings, conservation areas, and properties with specific planning conditions.

Parts of Boston town centre have conservation area designations that may restrict what’s permitted; we’ll advise on your specific situation during your free design visit.

Generally, conservatories are exempt from Building Regulations provided they meet specific criteria: they must:

• be built at ground level
• their floor area must not exceed 30 square metres
• they must be separated from the main house by external-quality walls, doors or windows
• they must have an independent heating system with separate temperature and on/off controls.

If your conservatory doesn’t meet these conditions, for example, if it’s very large, if you plan to remove the wall between it and the existing house, or if it’s connected to the main heating system, Building Regulations approval will be required.

We’ll flag this during your design visit if it applies to your project.

Orangeries and modern glass extensions sometimes fall outside the exemption, particularly on larger projects, and we’ll advise accordingly.

Possibly, but with restrictions.

Properties within conservation areas in Boston are subject to additional controls under permitted development rules.

In a conservation area, you are not permitted to clad the exterior of the house with stone, artificial stone, pebble dash, render, timber, plastic or tiles, and certain types of extensions may require a planning application even when they would otherwise be permitted development.

The practical impact for conservatories varies; some designs are straightforward to approve even in conservation areas, particularly those using sympathetic materials and traditional styles.

We’d recommend contacting Boston Borough Council’s planning department for a pre-application discussion if your property is in a conservation area, and we’re happy to advise on which styles and materials are most likely to be looked upon favourably.

If planning permission was required and not obtained, the local authority has the power to issue an enforcement notice requiring you to remove or alter the structure.

While enforcement action isn’t guaranteed,  particularly for structures that have stood for four years or more, it can become an issue when you come to sell your property, as solicitors will ask for evidence of planning consent or permitted development status.

Building without required consent can also affect your home insurance.

We always advise getting the permissions right from the outset, and we’ll help you establish what’s required during the design process.

In most cases, yes.

A well-built conservatory that is in keeping with the property and genuinely usable year-round is consistently cited by estate agents as one of the higher-return home improvements you can make.

The key word is “usable”, a cold, dated polycarbonate-roofed conservatory that’s clearly unusable in winter may not add the same value as a warm, well-finished space that functions as a proper room.

In the Lincolnshire property market, additional usable living space is particularly valued in family homes, and a conservatory that reads as a genuine extra reception room or dining space will typically command a better return than one that’s clearly a garden room that’s too cold to sit in from October to April.

Our recommendation is always to invest in the roof specification; a warm tiled roof may cost more upfront but pays back both in daily usability and in the impression it makes on future buyers.

Generally, yes.

A conservatory is considerably less expensive than a full single-storey extension of equivalent floor area.

A full extension involves more complex structural work, higher material costs, and more extensive Building Regulations requirements.

A conservatory achieves similar additional floor space at a lower cost, though the thermal performance and long-term maintenance costs differ.

The most cost-effective option for maximum liveable space at the lowest outlay is usually a uPVC lean-to or Edwardian conservatory with a warm tiled roof.

An orangery or modern glass extension sits between a conventional conservatory and a full extension in terms of both cost and finish; it’s worth considering if budget allows, as the end result is significantly closer to a proper room.

As a general guide:

Victorian and Edwardian styles suit period properties:  Victorian terraces, Edwardian semis, and inter-war housing are common across Boston and the surrounding villages.

The Victorian’s curved bay front particularly complements ornate brick properties.

The Edwardian’s square footprint maximises usable space and suits symmetrical, larger homes.

Lean-to conservatories are the most versatile in terms of planning: their low single-pitch roof works under almost any eave height.

They suit bungalows, 1960s and 1970s houses, and properties where height is a consideration.

Gable-end conservatories make a bold statement and tend to suit larger detached properties with the space to carry them.

Orangeries work beautifully on Georgian, Victorian and Edwardian properties as well as contemporary homes where a quality, room-like finish is the priority.

We’ll advise on the best fit for your specific property and plot during your free design visit.

Under permitted development, the conservatory must not cover more than 50% of the land around the original house.

In practice, for most Boston properties, this allows for a generous conservatory footprint!

The constraint tends to be the practical size of the available garden rather than the 50% rule itself.

For properties where the rear garden is limited in depth, a lean-to is often the most practical choice as it requires less projection from the rear wall.

We’ll assess your plot and advise on maximum practical dimensions during the design visit, taking into account permitted development rules, your garden space, and any boundary or neighbouring property considerations.

Yes, and it’s increasingly popular.

Bi-fold doors across the front or side elevation of a conservatory create a seamless connection between the conservatory and the garden when open; on warm days the entire front of the room can be folded back, effectively turning the conservatory into a covered outdoor space.

Sliding patio doors are an alternative where space doesn’t allow for the full swing arc of bi-fold panels.

We can incorporate both into conservatory designs and match the door specification to the overall frame system.

Absolutely.

It’s one of the most popular uses we hear from Boston homeowners considering a new conservatory.

The key to making it work as a year-round office is the roofing specification.

A warm tiled roof is strongly recommended: it provides a comfortable, stable temperature in winter without requiring constant heating, eliminates the distracting sound of rain on polycarbonate, and significantly reduces glare compared to a fully glazed roof .

… Important if you’re working on screens.

We’d also suggest solar control glazing on south- or west-facing walls to manage afternoon heat gain in summer.

A warm roof is a solid, insulated tiled roof system fitted to a conservatory frame in place of the conventional glass or polycarbonate panels.

The name refers to where the insulation sits: above the structural deck, keeping the entire roof construction warm and preventing cold bridging.

The result is a room that behaves thermally much more like a conventional insulated room than a glass structure, staying comfortable across a much wider range of outdoor temperatures.

We recommend warm roofs for most Lincolnshire homeowners because the county’s climate, cold winters, coastal wind exposure, and significant seasonal temperature variation make a poorly insulated conservatory roof a significant practical liability.

Homeowners who upgrade from polycarbonate to a warm roof consistently describe the change as transformative, and it’s the single most impactful decision you can make for year-round conservatory comfort.

Yes.

Inset roof windows are a popular addition to warm roof conservatories, and they resolve the most common concern people have about tiled roofs: the loss of natural light.

Velux roof windows, fixed roof lights, or a central glazed lantern section can all be incorporated into a warm roof design, allowing light in from above while maintaining the excellent thermal performance of the insulated panels around them.

We’ll discuss the options and position them appropriately for your aspect and orientation.

This depends almost entirely on the roofing material. A polycarbonate roof is notoriously noisy in heavy rain. A problem that many homeowners find genuinely disruptive to conversation, sleep, and work.

A glass roof is considerably better but still audible.

A warm tiled roof is effectively silent in rain, just like any other part of your house roof; the insulation layer and solid deck absorb all sound.

If noise is a concern, a warm roof is the clear answer.

A well-installed warm tiled roof will last as long as any conventional house roof, typically 30–50 years with minimal maintenance.

Quality glass roofs with good seals and proper drainage should last 20–30 years before any significant maintenance is needed.

Polycarbonate roofs tend to discolour and lose clarity over time, typically requiring replacement within 10–20 years depending on quality and exposure.

This is one of the reasons we recommend investing in a warm or glass roof where budget allows — the long-term maintenance cost difference is significant.

uPVC conservatories are designed to be low-maintenance, but a little regular attention keeps them looking their best for longer.

• Wipe down uPVC frames two or three times a year with a mild soapy solution and a soft cloth; avoid abrasive cleaners or solvents.
• Clean the glazing with a standard glass cleaner or, if fitted, allow self-cleaning glass to do its work after rain.
• Apply a light silicone spray to door and window seals annually to keep them supple and effective.
• Check drainage channels and any guttering periodically to ensure they’re free of leaves and debris; blocked drainage is the most common cause of water ingress in conservatories.

It depends on the structure and condition of the existing conservatory.

In some cases, an existing frame can be extended, particularly if the original installation was well-built and the frame is structurally sound.

In many cases, however, it’s more cost-effective and architecturally cleaner to remove the existing structure and start fresh, as extending an older conservatory can be complicated by changes in building standards, frame compatibility, and the difficulty of matching older profiles.

We’ll assess your existing conservatory honestly and advise which approach makes more sense for your situation.

In most cases, yes.

A properly built and permitted conservatory is treated as part of the structure of your home for insurance purposes.

You should inform your home insurer when your conservatory is complete and provide them with the approximate rebuild cost, as this will need to be reflected in your buildings insurance sum insured.

Failure to notify your insurer could affect a future claim.

If planning permission was required and not obtained, some insurers may be reluctant to cover the structure, another good reason to ensure all permissions are in order from the outset.
