Why Rising Supplier Costs Matter When Planning an Oak Glazed Extension

When you are considering a bespoke oak conservatory, orangery or garden room, it is entirely reasonable to want the best possible price. It is also important to understand what goes into producing that price—and why reputable quotations cannot always remain unchanged indefinitely.

A recent article published by Double Glazing Blogger, “Supplier Price Increases Hit Merchants Hard”, highlights the pressure affecting builders’ merchants and the wider construction industry. Drawing on the latest MRA Building Market Reports survey, it identifies supplier price rises as the single biggest concern for many merchants.

According to the report, 84% of merchants had experienced supplier price rises as a problem during the second quarter of 2026. Squeezed margins were cited by 64%, while 66% had struggled with longer lead times and 58% had encountered difficulties with product availability.

Those figures help explain something we deal with every day at Richmond Oak Glazed Extensions: giving our clients the most competitive price possible while maintaining the quality, craftsmanship and dependable service expected from a genuinely bespoke glazed extension.

A Bespoke Extension Relies on Many Suppliers

An oak glazed extension is not an off-the-shelf product. Every project brings together carefully specified materials, specialist skills and logistical arrangements.

Seasoned oak, high-performance glass, aluminium components, roofing materials, bricks, insulation, fixings and transport all contribute to the final cost. Price increases in any one of these areas can affect a quotation. When several rise together, the effect can become significant.

Transport is increasingly important too. Large oak frames, glazed units and other specialist materials must be moved safely and delivered at the correct stage. Fuel, haulage and delivery surcharges can therefore affect costs even when the underlying material price has not changed.

Product availability matters just as much. A particular glazing specification, roof component or matching brick may suddenly have a longer lead time. In a bespoke project, replacing it with the cheapest available alternative is rarely appropriate. Materials must suit the design, deliver the required performance and complement the property.

Why Our Quotations Are Valid for 14 Days

Before a contract is agreed, a Richmond Oak quotation remains valid for 14 days. This is not intended to pressure anyone into a quick decision. It allows us to price the project accurately against current supplier costs and availability.

In a market where manufacturers and merchants can revise prices with little notice, leaving our quotations open indefinitely would mean either adding a large contingency to every price or risking substantial increases before a client proceeds.

Neither approach benefits the homeowner.

A clear 14-day quotation period allows us to offer a realistic and competitive price based on current information, rather than inflating the figure to protect against every possible future increase.

Price Protection After Signing

Once your contract with Richmond Oak has been signed, the agreed price is held for six months. Supplier price increases arising during that period are not passed on to you.

This gives our clients valuable certainty when planning a major home improvement. You know the agreed project price and can arrange your finances with greater confidence, even if the cost of oak, glazing, roofing products or other materials rises afterwards.

There are occasions when Richmond Oak absorbs supplier increases to protect the price agreed with our client. We also work behind the scenes to plan purchases, coordinate suppliers and manage deliveries as efficiently as possible.

Wider market pressures do not disappear, but we use our experience and supplier relationships to reduce their impact wherever we reasonably can.

The Cheapest Quotation Is Not Always the Best Value

Rising costs create pressure across the industry to compete primarily on price. As the source article notes, customers may be encouraged towards lower-cost products when prices increase.

For a simple, standardised purchase, choosing the cheapest option may be straightforward. A bespoke glazed extension is very different.

A considerably cheaper quotation may be based on lower-grade timber, a reduced glazing specification, less experienced labour, fewer services or important elements being excluded from the initial price. Additional costs may then appear after work begins.

That does not mean the highest quotation is automatically the best. It means quotations should be compared carefully and on a genuine like-for-like basis.

Consider the quality and seasoning of the oak, the glass specification, foundations and roofing, the design and planning support included, the standard of craftsmanship and who will coordinate the complete project. The company’s experience is also important, particularly if your home is listed, lies within a conservation area or presents unusual design challenges. Richmond Oak regularly works with listed properties and homes in conservation areas, National Parks and Areas of Outstanding Natural Beauty.

True value comes from achieving the right result, using suitable materials and knowing the company responsible will remain accountable from design through to completion.

Fair and Transparent Pricing

At Richmond Oak Glazed Extensions, we cannot control global material costs, supplier increases or transport charges. We can control how honestly and carefully we respond to them.

Our aim is to provide the best possible price without compromising the qualities that make a Richmond Oak extension special: thoughtful bespoke design, carefully selected materials, experienced craftsmanship and a finished space that feels entirely at home with the existing property.

The pressures described by Double Glazing Blogger are real and affect businesses throughout the supply chain. By being open about them, setting clear quotation periods and protecting agreed prices after contract, we believe we give clients both fairness and confidence.
