Lock-up garage block insurance covers investors and landlords who own rows of garages let to local residents and businesses. The policy usually includes buildings cover for the garages, property owners' liability for the forecourt and access road, and loss of rent if garages can't be let after damage. Garage blocks can be awkward to insure because they are often unmanned, built with asbestos cement roofs, prone to fly-tipping and arson, and let to people who may store vehicles, fuel or business stock. Many standard landlord policies won't cover them, or treat them as unoccupied. Insurers want to know the number of garages, construction, what the licence or tenancy says about use, how the site is secured and how often it is visited. Blocks bought from councils often come with repairs and roof issues that need to be explained up front.

Own a block of lock-up garages? We'll find insurers who will cover the garages, the forecourt and the rent.

Key facts at a glance

  1. Standard landlord policies often exclude garages. Many only cover garages that belong to a house.
  2. Asbestos roofs are common. Insurers ask about condition and any survey.
  3. Arson and fly-tipping drive claims. Security and regular visits make a difference.
  4. What is stored matters. Vehicles, fuel and business stock raise the fire risk.
  5. Liability is easily overlooked. Forecourts and access roads can cause injury claims.

Who needs garage block insurance?

We insure owners of garage sites from a single row of six to portfolios spread across several towns.

  • Private investors. Buyers of garage blocks at auction or from councils.
  • Portfolio owners. Investors with several garage sites.
  • Developers. Garage sites held for future housing development.
  • Freeholders. Blocks of flats with separate garage courts.
  • Housing associations. Garage courts on housing estates.

What does garage block insurance cover?

CoverWhat it protectsWatch out for
BuildingsThe garages, doors, roofs and wallsAsbestos removal costs after a claim
Property owners' liabilityInjury on the forecourt, access road and landUnlit or potholed access roads
Loss of rentRent lost after insured damageNot always offered on low-value blocks
Malicious damageVandalism to doors and roofsHigher excesses on unmanned sites
Debris removalClearing the site after a fireLimits too low if asbestos is involved

If the garages sit on land you plan to develop, or the block is already empty, read our guides to derelict building insurance and auction property insurance.

Why are garage blocks harder to insure than they look?

A row of garages looks like a simple risk. Insurers see an unmanned site, often with an old roof, full of things nobody has checked.

Most garage blocks were built in the 1960s and 1970s with asbestos cement roof sheets. They are generally safe if left alone, but a fire or storm turns them into a hazardous clean-up, and that pushes up the cost of even a small claim. Many insurers ask for an asbestos survey, and some limit cover until damaged sheets are replaced.

Use matters too. A garage holding a family car and a lawnmower is one thing. A garage used as a workshop, a store for a market trader's stock or a place to keep jerry cans is another. Your licence agreement should spell out what is allowed, and you should check from time to time that it is being followed.

Don't insure garages on a house policy

Garages bought separately from a house, or let to people who don't live with you, are a commercial risk. A home or standard landlord policy is unlikely to cover them.

What do insurers ask?

  • Number of garages and how many are let
  • Wall and roof construction, and any asbestos survey
  • Who the garages are let to and what for
  • Whether any are used for business or vehicle repair
  • Site security, lighting and gates
  • How often the site is visited
  • Fly-tipping and vandalism history
  • Claims in the last five years

How do you get the best terms?

  1. Get an asbestos survey. And keep it with your insurance papers.
  2. Use a proper licence agreement. Set out what can and can't be stored.
  3. Visit regularly. Keep a short log of each visit.
  4. Clear rubbish quickly. Fly-tipped waste invites arson.
  5. Fix doors and roofs promptly. Damaged garages attract more damage.
  6. Insure the portfolio together. Several sites on one policy often costs less.

Where the information comes from

Our articles are compiled from a range of sources: regulators and public bodies such as the FCA, the Civil Aviation Authority, the Health and Safety Executive and Companies House; government publications and legislation; industry and trade bodies; insurer and market documentation; and published research and news reporting. Not everything stated originates from Miller & Partner. Where information comes from a third party we believe it to be accurate at the date of publication, but we haven't independently verified every external source and we don't warrant its accuracy or completeness. Where a point matters to a decision you're making, go to the original source and check it.

Figures, examples and case studies

Premium ranges, cost figures, limits and worked examples are illustrative only. They are not quotations, not offers of cover, and no cover is provided or implied on the basis of them. What you're actually charged depends on underwriting, and what you're actually covered for depends on the policy wording issued to you. Where an article includes a claim example, scenario or case study, it is illustrative unless we say otherwise — such examples are typically composites written to show how a policy section responds, and they don't describe an identifiable client, claim or settlement.

Interactive tools

Any calculators, cover checkers, risk assessors or similar tools on our site produce general guidance from the small number of answers you give them. They can't see your business, and their output is not a personal recommendation, an assessment of your actual risk, or a quotation.

Rules and market conditions change

Law, regulation, tax treatment, insurer appetite and policy wordings all change, sometimes at short notice. Content is accurate to the best of our knowledge on the date shown on the article and we don't undertake to update it as things move. An article you're reading some time after publication may be out of date.
