Buying a listed home means taking on legal responsibilities as well as an old building. A listed building survey should look at two things: the physical condition of a building that was built to work very differently from a modern house, and whether past alterations and repairs were appropriate and properly consented. For most listed and period homes, a RICS Home Survey Level 3 is the right choice. This guide explains why, and what else to check before you buy.
What does “listed” mean?
A listed building is one recognised as being of special architectural or historic interest and given legal protection. In England, listed buildings are recorded on the National Heritage List for England, maintained by Historic England. There are three grades:
| Grade | Meaning | Share of listed buildings |
|---|---|---|
| Grade I | Exceptional interest | About 2.5% |
| Grade II* | Particularly important, more than special interest | About 5.8% |
| Grade II | Special interest | About 91.7% |
Most listed homes are Grade II. The grade doesn’t change the basic legal duty: consent rules apply to all three.
Importantly, listing covers the whole building, inside and out, not just the front elevation. It can also extend to structures fixed to it and to some older structures within its curtilage (the land around it), such as boundary walls and outbuildings.
How to check if a property is listed
Search the National Heritage List for England by address or name. The list entry gives the grade, the date it was listed and a description. Treat that description as a guide to why it was listed, not a complete inventory of what is protected: features not mentioned can still be protected.
Your conveyancer’s local authority search should also reveal listing and whether the property is in a conservation area. If you’re in Wales or Scotland, separate bodies keep the lists.
What is listed building consent?
Under the Planning (Listed Buildings and Conservation Areas) Act 1990, you need listed building consent (LBC) from the local planning authority for any demolition, or any alteration or extension that would affect the building’s character as a building of special architectural or historic interest. Carrying out such works without consent is a criminal offence.
In practice, LBC is commonly needed for:
- extensions and internal alterations, including removing walls, fireplaces, doors, panelling or historic plasterwork;
- replacing windows or doors, including fitting double glazing;
- changing roof coverings, rendering or painting the outside where character is affected;
- repairs that change the fabric or use different materials, such as cement repointing or replacing lime plaster with gypsum;
- some insulation and energy-efficiency measures.
Like-for-like routine maintenance may not need consent, but the line isn’t always obvious. Your local authority’s conservation officer is the person to ask, and it’s worth asking before work starts.
Why unauthorised works matter when you buy
This is the part many buyers don’t realise. Historic England’s guidance explains that the local planning authority can take enforcement action, without time limit, requiring those responsible, or a subsequent owner, to reinstate or make good lost or damaged fabric. If an enforcement notice isn’t complied with, the current owner can be liable.
So if a previous owner swapped sash windows for uPVC, removed a fireplace or knocked through a wall without consent, the problem can become yours. Before you exchange:
- ask the seller for all listed building consents and approved drawings for past work;
- compare what’s there against what was consented;
- ask your conveyancer to check the local authority’s records;
- where something looks unconsented, take advice before committing. Putting it right can be costly.
A good listed building survey will point out alterations that look modern or inappropriate, so your conveyancer knows what to ask about.
Why a Level 3 survey is usually the right choice
The Level 3 survey is designed for older, unusual or altered properties. For listed homes it’s normally the right level because:
- it gives a fuller description of the construction and how the building is meant to work;
- it looks at defects and their likely causes in more depth, with advice on repair options and the consequences of leaving them;
- it comments on past repairs and alterations, including materials that may be doing harm;
- it is more useful when you’re planning work and need to understand what you’re dealing with.
A Level 2 survey is designed for conventional homes in reasonable condition and is rarely the best fit for a listed building. Our guides to which survey level you need and the types of house survey go into the differences. Level 3 surveys start from £570, with a fixed fee quoted for the property.
Common problems in listed and period homes
Breathability
Most listed homes were built with solid walls of stone, brick or timber frame, with lime mortar, lime plaster and limewash. These materials let moisture in and out, and the building relies on that to stay dry. Historic England’s guidance on damp in historic buildings explains how traditional buildings manage moisture differently from modern ones.
Inappropriate past repairs
Some of the most common problems in period buildings stem from modern materials:
- cement pointing and render trapping moisture in soft stone and brick (see our guide to lime mortar vs cement repointing);
- gypsum plaster and plastic paints on solid walls;
- chemical damp-proof courses and tanking that don’t suit the construction;
- raised ground levels or hard paving against walls;
- spray foam or vapour-tight insulation in roofs (see spray foam insulation).
These often cause the damp they were meant to cure. In listed buildings, some of them may also be unauthorised works.
Roofs, chimneys and rainwater goods
Old roofs, valleys, parapet gutters and chimneys need regular maintenance. Defective rainwater goods are one of the most common causes of damp in old buildings, and one of the cheapest to fix.
Timber decay and insect attack
Old timber frames, floors and roof structures can suffer from wet rot, dry rot and woodworm, often linked to a moisture source. Our guides to dry rot vs wet rot and woodworm cover what to look for.
Structural movement
Old buildings often have historic distortion from shallow foundations or decayed timbers. Much of it is old and stable, but it needs judging properly.
Listed homes in Yorkshire and the Pennines
Around Huddersfield and the Pennine towns, many listed homes are former weavers’ cottages, farmhouses, laithes and terraces in local sandstone and gritstone, often with stone slate roofs and mullioned windows. Exposure to driving rain, combined with decades of cement repointing and modern finishes, is a frequent cause of damp in these buildings.
Conservation areas
Being in a conservation area is different from being listed. Historic England explains that conservation areas bring some extra planning controls, mainly affecting work to the outside of buildings and to trees. Some areas also have Article 4 Directions that remove permitted development rights, so changes like replacement windows or doors may need planning permission. You must notify the council before work to most trees, and demolition needs planning permission.
A house can be both listed and in a conservation area.
Getting the right advice
Before you buy a listed home:
- Check the list entry and grade.
- Get the consent history from the seller and your conveyancer.
- Commission a Level 3 survey from a surveyor comfortable with traditional construction.
- Speak to the conservation officer before you plan any work.
- Budget for maintenance in traditional materials, which can cost more than modern equivalents.
We carry out Level 3 surveys on period and listed homes across a 90-minute radius of Huddersfield. Get in touch with the address and the list entry if you have it.
