How Restrictive Covenants Impact Market Valuation
A restrictive covenant is a legally binding obligation placed in the title deeds of a freehold property that restricts how the landowner can use or develop their land.
First established under English common law in the landmark case of Tulk v Moxhay (1848), restrictive covenants 'run with the land' in equity. This means they bind all future purchasers indefinitely, regardless of how many times the property is bought and sold.
The impact on property value depends entirely on the nature of the restriction and the buyer's intentions:
1. Harmless / Value-Preserving Covenants: Covenants restricting anti-social behavior, preventing commercial scrap yards or pubs in residential developments, or requiring front gardens to remain open-plan generally protect the visual amenity of an estate and maintain property values.
2. Value-Depressing Covenants: Covenants that prohibit building extensions, restrict the property to a 'single private dwellinghouse', or prevent loft conversions and outbuildings can severely impair capital growth. For example, a house with space for a £150,000 building plot is devalued by that exact development potential if a strict 'no additional building' covenant cannot be modified.
| Covenant Type | Common Example | Estimated Value Impact | Conveyancing Solution |
|---|---|---|---|
| Single Dwelling Only | Prohibits splitting plot or building second home | 10% to 30% reduction in development value | Section 84 Upper Tribunal application or indemnity |
| Building Consent Restriction | Requires historic developer sign-off for extensions | 0% to 5% (delays conveyancing exchange) | Title indemnity insurance (£150–£300) |
| No Trade / Business | Bars running commercial enterprises or workshops | 0% for residential buyers (15%+ for investors) | Indemnity policy or deed of release |
| Standard Estate Amenity | No caravans in driveway, no livestock or poultry | 0% (Neutral or preserves amenity) | None required (Standard UK estate rule) |
Mortgage Lender Attitudes to Restrictive Covenants
UK mortgage lenders (governed by the UK Finance Mortgage Lenders' Handbook) do not object to the mere existence of restrictive covenants.
However, lenders will immediately refuse loan drawdown if there is an unindemnified breach. For example, if a previous owner built a two-storey rear extension in direct violation of a 1950s covenant stating 'no alterations without vendor approval', the lender requires either:
• An official, signed Deed of Release from the covenant beneficiary; or
• A comprehensive Restrictive Covenant Indemnity Insurance policy taken out for the full market purchase price.
If you discover a breached restrictive covenant during conveyancing, NEVER contact the person or developer holding the covenant to ask for permission. The moment you alert the beneficiary, all insurance underwriters are legally prohibited from issuing an indemnity policy.
