 Trustindex verifies that the original source of the review is Google. We're so pleased with how the windows turned out, the refurbished frames look so good. Anecdotally, they seemed to have improved the soundproofing,  although we live practically on top of a main road,  so does not completely shut out the noise, the casement windows more than the bay windows. Cannot comment on the thermal quality as they were done in the middle of the heatwave, but we are fairly confident there will be a big improvement come winter. Cannot fault the workmen, they were reliable and extremely hard working, even when it was 30C +

Would definitely use them again if we ever needed windows to be refurbished in future.

 Trustindex verifies that the original source of the review is Google. Very happy with the new windows they look fantastic.
Keeping the original windows was so important to us and you have made that possible.
We only had the upstairs completed and can't believe the difference in the sound and temperature from downstairs.
Will be booking the downstairs in ASAP.
The team are also fantastic and worked incredibly hard they treated our home with respect and keep evething as clean as they can.
I would definitely recommend.
Hopefully we will get the same team next   time!
The neighbours are also asking who done the work and have commented on how hard you worked !
Very happy customers.

A genuinely reassuring experience from start to finish. If you've got a heritage property and you're agonising over who to trust, look no further. Highly recommended.

 Trustindex verifies that the original source of the review is Google. Scott James did our restoration work years ago, so when it came time to sort the insulation, there was no question who we'd call. Glad to say they're still the same lot. Still doing things properly.
The new VIG glazing has made the house genuinely warmer, and a fair bit quieter too. Lovely to see familiar faces, lovely to see they still take pride in the work. Wouldn't go anywhere else

 Trustindex verifies that the original source of the review is Trustindex. Exceptional sash window restoration experience
We had a great experience having our sash windows double glazed and draught proofed. We were very impressed by the quality of the work and the team’s craftsmanship from the start. From the initial consultation with Alex right through to the restoration of the windows, the experience was seamless. They were clearly experts in their field.

 Trustindex verifies that the original source of the review is Google. The end result genuinely surprised us. The original frames have been brought back to life sanded, restored, repainted and the new glazing has made a noticeable difference to both the temperature and the noise from the road. For roughly what secondary glazing would've cost, we've got something that actually looks like part of the house rather than bolted onto it.

Reglazing windows in listed properties

Inefficient glazing contributes to almost 10-20% of heat loss in a period property. Reglazing and draught-proofing existing sashes is the perfect solution. It improves energy efficiency and leaves the original windows intact.

Single glazed windows vs double glazing.

Reduce outside noise and increase windows security

Double-glazed, vacuum-insulated units that we fit into existing sashes are much harder to break than single-pane windows and reduce outside noise more efficiently.

Timber frame restoration

Restoration can be a cost-effective way to bring timber windows back to their original condition and has a number of benefits over the full listed building window replacement.

It helps to preserve the historical value of the property and does not require planning permission from the conservation officer.

Stop draughts

Draught-proofing & Reglazing service is an ideal solution for homeowners listed buildings who want to improve their home’s energy efficiency but can not replace the windows completely due to regulations.

Windows in Listed and conservation area properties

Scott James Sash window restoration specialists have extensive experience in all aspects of sash window restoration in Listed buildings, including reglazing existing windows with double glazing.

Approximately half of our wooden window restorations are for Grade II Listed or regulated conservation area properties.

With our wealth of experience in sensitively preserving your property’s heritage, we stand by our view that for over 90% of cases, repair and maintenance produce higher-quality, more cost-effective results than replacement.

To avoid unnecessarily removing and destroying perfectly reparable original windows, it is important to seek proper advice and avoid hastily replacing these beautiful traditional details.

The Scott James restoration team have spent decades refining their methods to accommodate planning policies and work with original materials whilst delivering exceptional results.

Which work requires planning permission and which does not?

What type of work is done to the window?	Permission is required	Permission is not required

Re-painting with different colour	✅
Draught-proofing		✅
Reglazing existing sashes with double-glazed units	✅
Sashes only replacement	✅

In most cases, minor repairs and improvements such as draught sealing, painting and overhaul servicing can be completed without planning permission.

Whenever the building and its character are not altered during the restoration process, prior approval may not be needed from the local regulatory body (e.g. replacing the glass of a similar thickness is often permitted).

The likelihood of receiving a permission

Nonetheless, you can do many things with your listed building’s windows; replace, repair, and reglaze; the likelihood of receiving permission varies between the options.

What type of work is done to the window?	Likelihood of receiving a permission
Re-painting with different colour	Medium – High ✅
Reglazing existing sashes with double-glazed units	Medium – High ✅
Sashes only replacement	Low – Medium ❌
Full box and sashes replacement	Low ❌
Full replacement to UPVC	Impossible – Low ❌

How do we help our customers with the planning application?

Our customer, who plans to reglaze sashes with double-glazed units, receives a pack of documents with approved past planning applications from different local councils to support their application.

Cost of repairing windows in Grade 2 Listed Buildings

Alex

The original wooden windows in listed properties can be beautifully restored and include glazing upgrades to suit a modern lifestyle.

By preserving original wood – typically of a higher quality – listed building window restorations are much less resource-intensive, which is excellent for the planet.

Replacement rather than professional restoration will require planning permission and can incur extra costs, time and resources.

FAQs

Can I reglaze sashes in Grade 2 listed building?

Approval from the local conservation officer is required for reglazing your existing sashes; however, we see a high approval rate in the past years for this type of work as it is more sympathetic to the original windows.

Can I replace windows in a listed building?

The short answer is that it depends on the level of protection that has been placed on the property. If the building is grade I, II*, or a grade 2 listed building, then any alterations to the windows, including window replacement, would need to be approved by the local planning authority.

Can you have UPVC windows in a listed building?

While UPVC is a popular material for both new build and replacement windows, it is not typically allowed in listed properties. UPVC windows are not maintaining the historic appearance of the period property. In some cases, however, it may be possible to get permission to install UPVC windows if they are designed to blend in with the existing architecture.
