Housing stock in Windsor
The historic town centre around the castle and High Street has a dense concentration of listed and locally listed Georgian and Victorian buildings, generally solid-walled with variable heating standards depending on modernisation history; achievable ratings here are often constrained by what can physically be changed. Clewer and Dedworth have more conventional interwar and post-war cavity-walled semis and terraces, generally a good candidate for insulation upgrades where not already fitted. Newer development towards the town's edges and around Windsor's business areas is assessed under current Part L standards and typically achieves B-C ratings. Flats above shops in the town centre vary considerably depending on when they were last refurbished.
Landlord rules and licensing in Windsor
Rental properties in Windsor must meet the MEES band E minimum, with the proposed band C requirement for new tenancies expected around 2028; landlords of listed or conservation area properties should plan improvement routes carefully given the added heritage constraints. The Royal Borough of Windsor and Maidenhead applies mandatory licensing to qualifying larger HMOs, with no blanket additional scheme across the town at present, so current designations should be confirmed before an application. Windsor's town centre conservation area and the large number of listed buildings mean external wall insulation and window replacement typically need listed building consent or planning permission, which we flag clearly in reports where it limits achievable ratings.
What we commonly find here
- Solid walls in listed and locally listed town-centre buildings limiting achievable ratings
- Sash and timber casement windows retained for character rather than upgraded in the historic core
- Unfilled cavity walls in Clewer and Dedworth interwar and post-war semis
- Older gas boilers in unmodernised town-centre properties
- Flats above shops with variable glazing standards depending on refurbishment history
- Newer edge-of-town development achieving consistently strong B-C ratings
Working in Windsor
Windsor is about 22 miles from Wembley, typically a 35-45 minute drive via the M4 and A308, in our outer travel band with no central London access charge relevant to this westward route. Parking in the town centre is tightly managed given the volume of visitors to the castle, so we generally use one of the multi-storey car parks and allow extra time; Clewer and Dedworth have more straightforward on-street parking. A domestic visit usually takes 25-40 minutes. Certificates are lodged on the Register the same or next working day, with same-day appointments available where scheduling allows.
EPCs for listed buildings in Windsor
A significant share of Windsor's town centre is listed or within a conservation area. We still carry out a standard RdSAP survey for these properties, but our reports explain where heritage constraints limit certain improvements such as external insulation or window replacement.
Parking and access near the Castle
Visits to properties close to the Castle and High Street need to work around pedestrianised areas and tourist footfall; we plan appointment times and parking in advance to keep visits efficient.

When you need an EPC in Windsor
A valid Energy Performance Certificate is required before a home in Windsor is marketed for sale or let, and it lasts ten years. Under the Minimum Energy Efficiency Standard a rented home must reach at least band E, and the government has proposed raising that to band C for rented homes by 2030, so a current certificate is also the starting point for planning upgrades. New builds and material conversions need SAP calculations at design stage and an on-completion EPC, and commercial premises need a non-domestic certificate produced on the same basis.
